Full Text	[Detailed Description of the Invention] [0001] [Technical Field to which the Invention Pertains] This invention relates to a rear part structure for a vehicle which is improved in seatability of a rider and loadability of a baggage, facilitates gripping of a rear grip by a hand and is improved in appearance of a rear part of a vehicle body. Further, where a clear lens is used for a lens of a winker, the observability of the winker is assured while the appearance of a rear part of a vehicle body is improved. [0002] [Prior Art] As another rear part structure for a vehicle, a rear part structure disclosed, for example, in the official gazette of Japanese Patent Laid-Open No. Hei 6-247361 "Motorcycle" is known. In FIGS. 2 and 3 of the official gazette mentioned, a rear part structure is shown wherein a rear grip 34 serving also as a carrier 32 is attached to a vehicle body cover 27 rearwardly of a driver seat 30 (those reference numerals which are used in the official gazette mentioned above are used here. This similarly applies to the following description). [0003] As another rear part structure for a vehicle, a rear part structure disclosed, for example, in the official gazette of Japanese Patent Publication No. Hei 7-90812 "Lamp Apparatus for a Motorcycle" is known. In FIGS. 1 and 3 of the official gazette mentioned above, a motorcycle is shown wherein flasher lamps 10, 10 are provided leftwardly and rightwardly on a rear part of a vehicle body and openings 22, 22 are provided in a side cover 19 sidewardly of bulbs 13, 13 provided in the flasher lamps 10, 10 and flasher lamp lenses 15, 15 which cover the bulbs 13, 13 such that they overlap partly with the bulbs 13, 13 as viewed in side elevation (those reference numerals which are used in the official gazette mentioned above are used here. This similarly applies to the following description). [0004] [Problems to Be Solved by the Invention] The driver seat 3 0 described above preferably has a seat face of a greater area for the sake of the seatability of a rider or the loadability of a baggage. However, if the width of the driver seat 3 0 is increased in order to increase the area of the seat face of the driver seat 30, then the width of the vehicle is increased, but if the overall length of the driver seat 30 is increased, then the balance of the driver seat 30 with the other surrounding parts and so forth is lost and the appearance of the rear part of the vehicle body is deteriorated. Further, since the rear grip 34 described above is positioned just rearwardly of the fellow passenger, the fellow passenger cannot grip the rear grip 34 readily. [0005] Therefore, it is a first object of the present invention to improve a rear part structure for a vehicle to improve the seatability of a rider and the loadability of a baggage, facilitate gripping of a rear grip by a hand and improve the appearance of the rear part of the vehicle body. [0006] On the other hand, for example, where the flasher lamps 15 are formed as clear lenses, the bulbs 13 cannot be observed fully from the outside. However, since the area of the openings 22 becomes small and the light amount decreases, it is desired to improve the observability of the flasher lamps 10 as viewed from sidewardly of the motorcycle. Further, the side faces of the rear part of the vehicle body in which the rectangular openings 22 are formed are poor in accent and lack in the charm in terms of the appearance. [0007] Therefore, it is a second object of the present invention to improve a rear part structure for a vehicle to assure, where a clear lens is used for a lens of a winker, the observability of the winker while improving the appearance of the rear part of the vehicle body. [0008] [Means for Solving the Problems] In order to attain the first object described above, according to claim 1, a rear part structure for a vehicle is characterized in that a rear portion of a tandem seat is extended rearwardly in a triangular shape as viewed in plan view, and a grip for a fellow passenger disposed rearwardly of the tandem seat is formed in a triangular shape substantially same as the shape of the rear portion of the tandem seat. [0009] Since the rear portion of the tandem seat is projected rearwardly in a triangular shape as viewed in plan view, the area of the rear portion of the tandem seat can be increased, and it can seat readily and a baggage can be loaded readily on the rear portion of the tandem seat. Further, since the grip for a fellow passenger is formed in a triangular shape substantially similar to the shape of the rear portion of the tandem seat, the two sides of the grip of the triangular shape are positioned sidewardly of the fellow passenger, and therefore, the fellow passenger can grip the sides of the grip readily with the hands. Further, the feeling of unity in design of the rear portion of the tandem seat and the grip increases, and the appearance of the rear part of the vehicle body can be improved. [0010] According to claim 2, the rear part structure for a vehicle is characterized in that a tail lamp unit is attached to a vehicle body below the grip, and also a rear end edge of the tail lamp unit is formed in a triangular shape substantially same as the shape of the rear portion of the tandem seat. Unity in design of the rear portion of the tandem seat and the grip as well as the rear end edge of the tail lamp unit is further improved, and the charm of the commodity can be augmented. [0011] According to claim 3, the rear part structure for a vehicle is characterized in that a stop lamp is provided at the center of the tail lamp unit, and a rear end edge of an upper face of a lens of the stop lamp is formed in such a shape that the width thereof decreases rearwardly. The shape of the upper face rear end edge of the lens of the stop lamp and the shape of the grip can be made similar to each other, and the design of the rear part of the vehicle body can be emphasized. [0012] According to claim 4, the rear part structure for a vehicle is characterized in that the opposite side edges of a rear face of the lens of the stop lamp is formed in such a manner as to have a width increasing downwardly. In addition to the emphasis of the design of the rear part of the vehicle body by the similarity of the shape of the upper face rear end edge of the lens of the stop lamp and the shape of the grip, the area of the face of the lens of the stop lamp as viewed in rear elevation can be secured. [0013] According to claim 5, the rear part structure for a vehicle according is characterized in that a seat face of the rear portion of the tandem seat and an upper face of a rear portion of the grip are positioned at a substantially same height. Since the seat face of the rear portion of the tandem seat and the rear portion upper face of the grip are positioned at a substantially equal height, it is advantageous when a baggage such as an elongated baggage is carried such that it extends between the rear portion of the tandem seat and the grip. [0014] In order to attain the second object described above, according to claim 6, a rear part structure for a vehicle wherein a stop lamp and a pair of winkers disposed on the opposite sides of the stop lamp are provided rearwardly of a body cover is characterized in that an extension of the body cover is formed in such a manner as to overlap with bulbs of the winkers, each of which includes a clear lens, as viewed in side elevation, and a rear edge of the extension is projected rearwardly upwards in a substantially V-shape as viewed in side elevation. [0015] The bulbs of the winkers which include the clear lenses can be prevented from being observed fully by the extension of the body cover, and besides the appearance of the rear part of the vehicle body can be augmented by the V-shaped rear edge of the extension. Further, the bulbs of the winkers are not covered completely by the extension, and the opposite sides of the V-shape assure lens faces of the winkers. Therefore, the observability of the winkers can be assured. [0016] According to claim 7, the rear part structure for a vehicle is characterized in that rear end edges of the lenses of the winkers are projected rearwardly upwards in a substantially in a V-shape as viewed in side elevation. Since the rear end edges of the lenses of the winkers are projected rearwardly upwards in a substantially V-shape as viewed in side elevation, together with the fact that the extension of the body cover is formed in a V-shape, the design of the V-shape of the lenses can appeal strongly, and the charm of the commodity can be augmented. [0017] According to claim 8, the rear part structure for a vehicle is characterized in that a rear end edge of a lens of the stop lamp is projected rearwardly upwards in a substantially V-shape as viewed in side elevation. [0018] Since the lens of the stop lamp is projected rearwardly upwards in a substantially V-shape as viewed in side elevation, the design of the V-shaped lens of the stop lamp can be made strongly appealing and unified together with the V-shaped extension of the body cover and the V-shaped lenses of the winkers, and the charm of the commodity can be augmented. [0019] [Mode for Carrying out the Invention] An embodiment of the present invention is described with reference to the accompanying drawings.

[0039] FIG. 8 is a perspective view showing essential part of the rear part of the vehicle body of the motorcycle according to the present invention and shows a state wherein a pair of rear winkers 92, 92 (the rear winker 92 on the interior side) of a large size are disposed rearwardly of the body cover 23. [0040] Referring back to FIG. 6, the rear winker 92 is positioned between the extension 23c of the body cover 23 and the stop lamp 91 as viewed in side elevation, and besides, the rear end edge 92b of the rear winker 92 has a substantially horizontally laid V-shape similarly to the substantially horizontally laid V-shaped extension 23c of the body cover 23 and the substantially horizontally laid V-shaped rear end edge 91b of the stop lamp 91. Therefore, the rear winker 92 can occupy a very large area between the extension 23c of the body cover 23 and the stop lamp 91. [0041] FIG. 9 is a side elevational view showing essential part of the rear part of the vehicle body of the motorcycle according to the present invention and shows that the extension 23c of the body cover 23 is formed such that it overlaps with a winker bulb 101 of the rear winker 92 as viewed in side elevational. [0042] Since the rear winker 92 adopts a transparent or translucent lens 92a which is not colored, the entire winker bulb 101 cannot be observed as viewed in side elevation thereby to improve the appearance while the entire winker bulb 101 is not hidden and the lens area is increased so that a decrease of the light amount is prevented to improve the observability from a remote place. [0043] FIG. 10 is a rear elevational view showing the rear part of the vehicle body of the motorcycle according to the present invention, and rear face side edges 91c, 91c at a lower portion of the lens 91a of the stop lamp 91 are formed such that the width thereof increases downwardly thereby to further increase the area of the lens 91a as viewed in rear elevation to improve the observability from a rear place. [0044] FIG. 11 is a perspective view showing the rear part of the vehicle body of the motorcycle according to the present invention and shows that the rear grip 24 is attached at three places to the vehicle body frame 31 (refer to FIG. 2) side by means of bolts 104, ... with the body cover 23 interposed therebetween. It is to be noted that a rear portion of the tandem seat 22 indicated by section lines is a triangular-shaped portion 22c which is hereinafter described. [0045] The rear grip 24 includes a V-shaped great width portion 24b and a pair of thin extensions 24c, 24c extending from the opposite ends of the great width portion 24b, and particularly the extensions 24c, 24c can be gripped readily by the hands since they are positioned sidewardly of the fellow passenger. [0046] FIG. 12 is a plan view of the rear part of the vehicle body of the motorcycle according to the present invention and shows that a rear portion of the tandem seat 22, that is, a rear portion of the fellow passenger seat 96, is projected rearwardly in a triangular shape as viewed in plan view and the rear grip 24 is formed in a shape substantially same as the shape of the rear portion of the tandem seat 22. [0047] In particular, a rear edge 22a of the tandem seat 22 is formed in a V-shape, and a central front edge 24d of the rear grip 24 is formed in a V-shape substantially same as that of the rear edge 22a of the tandem seat 22. [0048] Further, side edges 22b, 22b of the tandem seat 22 are formed with a width which decreases rearwardly and end portion front edges (that is, inner edges of the extensions 24c, 24c) 24e, 24e of the rear grip 24 are formed with a width which decreases rearwardly substantially similarly to that of the side edges 22b, 22b of the tandem seat 22. [0049] Since the triangular-shaped portion 22c indicated by section lines is formed at the rear portion of the tandem seat 22, the area of the fellow passenger seat 96 can be increased and the fellow passenger can be seated more readily. Further, it is convenient also to load a baggage. [0050] Also a rear edge 24f of the rear grip 24, a rear end edge 23d of the body cover 23, an upper face rear end edge 91d of the stop lamp 91 and a rear end edge 35a of the tail lamp unit 35 (the rear end edge 35a is a portion including the upper face rear end edge 91d of the stop lamp 91 and upper face rear end edges of the rear winkers 92, 92 as viewed in plan view) are formed so as to have a width decreasing rearwardly. [0051] By forming each of the rear edge 22a of the tandem seat 22, the central front edge 24d and rear edge 24f of the rear grip 24, the rear end edge 23d of the body cover 23, the upper face rear end edge 91d of the stop lamp 91 and the rear end edge 35a of the tail lamp unit 35 in a V-shape in this manner, a design having a unity can be achieved and provide a good impression as a design of a rear part of a vehicle body. [0052] FIG. 13 is a view of operation illustrating operation of the rear part of the vehicle body of the motorcycle according to the present invention and shows that an elongated baggage 106 is loaded on and secured by means of a rope 107 to the seat face 96a of the fellow passenger seat 96 of the tandem seat 22 and the rear portion upper face 24a of the rear grip 24. In this manner, where the seat face 96a of the fellow passenger seat 96 and the rear portion upper face 24a of the rear grip 24 are set to a substantially equal height, the baggage 106 can be loaded stably. [0053] FIG. 14(a) to FIG. 14(c) are illustrative views illustrating a baggage accommodation structure of the vehicle body of the motorcycle according to the present invention, and (a) is a perspective view illustrating a central portion of the vehicle body of the motorcycle 10, that is, the step floor 21 and shows that an upper lid 111 is provided on an upper face of the step floor 21 while a lower lid 112 is provided on the lower cover 38 below the step floor 21 to make it possible to make the most of an accommodation space (hereinafter described in detail) provided in the step floor 21. [0054] FIG. 14(b) is a horizontal sectional view of the step floor and shows that, since the step floor 21 is structured such that the vehicle body frame 31 and sub frames 114, 114 attached to a lower portion of the vehicle body frame 31 are disposed at the vertices of a triangle on a central portion of the step floor 21, a functioning part such as, for example, the radiator 51 is disposed in a central space 115 between the vehicle body frame 31 and the sub frames 114, 114 while an accommodation space 116 is formed sidewardly of the central space 115 and, for example, a theft preventing member 117 which may be soiled is accommodated in the accommodation space 116. The upper lid 111 is a member removably mounted on the step floor 21, and the lower lid 112 is a member mounted for opening and closing movement on the lower cover 38. [0055] The theft-preventing member 117 can be connected, for example, at one end thereof to a sub frame 114 and at the other end thereof to a member provided outside the vehicle such as a guardrail, a mast or a pole. Consequently, where the theft-preventing member 117 is used, it is necessary to connect only the other end of the theft preventing member 117, and the connecting operation can be performed readily. Further, since the one end of the theft preventing member 117 is connected to the vehicle body side, loss of the theft preventing member 117 can be prevented.
