[Title of the Invention] A SHROUD MOUNTING STRUCTURE OF A MOTORCYCLE
[Technical Field] [0001]
The present invention relates to the shroud mounting structure of a motorcycle for mounting a shroud which guides wind which a vehicle body receives during traveling to a rear portion of the vehicle on a vehicle body side.
[Background Art] [0002]
Conventionally, with respect to a motorcycle, there exists a case that shrouds are mounted on a front-side portion of a fuel tank in a left-and-right symmetry. The shrouds are provided for guiding wind during traveling to a rear portion of the vehicle and hence, it is necessary to impart the structure which can withstand the wind pressure during traveling to the shrouds. Accordingly, the conventional shroud mounting structure is, for example, configured such that a bracket is mounted on a vehicle body frame of a motorcycle and the shrouds are mounted on the bracket thus receiving an external force attributed to the wind pressure by the vehicle body frame (for example, see patent document 1).

[Problems that the Invention is to Solve]
[0003]
However, in the above-mentioned structure, it is necessary to remove a mounting portion of the bracket and the shrouds at the time of removing the fuel tank from the vehicle body side and hence, the mounting and dismounting of the fuel tank becomes cumbersome. Further, it is necessary to mount the bracket on the vehicle body frame using fastening members such as bolts or by welding and hence, there exists a drawback that the number of parts is increased or the assembling man-hours is increased. In view of the above, it may be considered that the shrouds are mounted only on the fuel tank. In this case, however, it is necessary to impart the structure which can suppress the generation of vibrations of the fuel tank and the shrouds attributed to the wind pressure during traveling.
[0004]
The present invention has been made under such circumferences and it is an object of the present invention to provide the shroud mounting structure of a motorcycle which can mount shrouds only on a fuel tank and can withstand the wind pressure during traveling. [Means for Solving the Problem]
[0005]
The present invention is characterized in that, in a

shroud mounting structure of a motorcycle comprising a fuel tank which includes a mounting portion for mounting the fuel tank on a vehicle body frame on a front portion thereof, and a shroud which is mounted on the front portion of the fuel tank and includes a vehicle-body-inner-side mounting portion and a plurality of vehicle-body-outer-side mounting portions, the plurality of vehicle-body-outer-side mounting portions are arranged behind the mounting portion for mounting the fuel tank on the vehicle body frame, and are arranged vertically with the mounting portion for mounting the fuel tank on the vehicle body frame sandwiched therebetween.
Due to such a constitution, it is possible to effectively disperse an external force which the vehicle receives due to pressure of a wind coming toward a front side of the vehicle to at least two outer mounting portions.
[0006]
Further, the outer-side mounting portions may be arranged vertically with the inner-side mounting portion sandwiched therebetween.
Due to such a constitution, it is possible to prevent the shrouds from being twisted at the inner-side mounting portion due to the pressure of wind coming toward the front side of the vehicle.
[0007]
In this case, the inner-side mounting portion may be

configured to be fastened to the fuel tank by a fastening member from a front side of the vehicle body.
Due to such a constitution, it is possible to maintain the external force which the vehicle receives due to the pressure of the wind coming toward the front side of the vehicle by a shearing force of the fastening member such as bolts.
[0008]
Further, the shrouds may be configured such that a shroud surface between the outer-side mounting portions is notched.
Due to such a constitution, the reduction of weight of the shrouds can be realized,
[0009]
Further, the shroud may form a grille opening in the shroud surface thereof, and at least one of the outer-side mounting portions may be arranged in the inside of the grille opening portion.
Due to such a constitution, for example, when fins for guiding the wind to the grille opening portion is mounted on the shrouds, it is possible to conceal the outer-side mounting portions with the fins.
[0010]
Further, the fuel tank may have a portion thereof which is overlapped to the shroud formed into a recessed portion.
Due to such a constitution, it is possible to impart the feeling of integrity of the shrouds and the fuel tank to the

shroud mounting structure and it is also possible to allow the presence of errors in a shape of the shrouds. [Advantage of the Invention] [0011]
According to the present invention, the outer-side mounting portions are arranged in a state that the outer-side mounting portions sandwich the mounting portion of the fuel tank from above and below. Accordingly, it is possible to effectively disperse the external force which the vehicle receives due to pressure of a wind coming toward a front side of the vehicle to at least two outer mounting portions . Further, the outer-side mounting portions are arranged behind the mounting portion of the fuel tank and hence, it is possible to increase a longitudinal span between the fuel tank mounting portion and the outer-side mounting portions. Accordingly, it is possible to effectively disperse the external force which the vehicle receives due to pressure of a wind to at least two outer mounting portions. As a result, the shrouds can be mounted on the fuel tank more firmly thus reducing an influence attributed to the traveling wind to the vehicle. [Best Mode for Carrying out the Invention]

[0026]
Fig. 7 is a front view of the outer member 100b of the shroud 100 as viewed from the outside, and Fig. 8 is a plan view of the outer member 100b of the shroud 100 shown in Fig. 7 as viewed from above.
The outer member 100b, as shown in Fig. 7 and Fig. 8, has a complicated curved shape with a predetermined plate

thickness, and a front surface of the outer member 100b shown in Fig. 7 constitutes the outer surface (shroud surface) of the shroud 100. The outer member 100b is, as shown in Fig. 7, formed into a shape having a projecting portion 121a on a vehicle-body front side thereof (a left side of Fig. 7), and the outer member 100b includes an upper oblique side 121b which extends in the vehicle-body rearward and obliquely upward direction from the projecting portion 121a, an upper end portion 121c which is arranged on an upper portion of the upper oblique side 121b, a lower oblique side 121d which extends in the vehicle-body rearward and obliquely downward direction from the projecting portion 121a, and a lower end portion 121e which is arranged on a lower portion of the lower oblique side 12Id. Further, a vehicle-body-rear-side side of the outer member 100b includes a vehicle-body frontwardly-notched shape (constricted shape), and the notch is arranged between two mounting holes 127, 128 described later and extends in front of two mounting holes 127, 128. The notched shape is substantially equal to a shape of an outer periphery of the groove portion 11a of the fuel tank 11. [0027]
On a peripheral portion of the lower oblique side 121d of the outer member 100b, three boss portions 123 are formed along the lower oblique side 121d, and in the boss portions 123, threaded holes 122 are formed. Further, on a peripheral

portion of the upper oblique side 121b of the outer member 100b, one boss portion 123 is formed in the vicinity of the upper end portion 121c, and the threaded hole 122 is formed in the boss portion 123. These four threaded holes 122 are, when the projecting portions Ilia, 112a of the inner member 100a and the outer member 100b, the upper oblique sides 111b, 121b, and the lower oblique sides llld, 121d are respectively combined and are assembled, aligned with portions of four mounting holes 112 of the inner member 100a. The inner member 100a and the outer member 100b are fastened to each other using the fastening members 115 (see Fig. 3) such as threads which are passed through the mounting holes from the mounting holes 112 side (inner member 100a side) to the vehicle-body outside.
[0028]
Further, in the outer member 100b, as shown in Fig. 7, a grille opening portion 12 6 which is constricted in a substantially diamond shape is formed. In the bottom surface of the grille opening portion 126, a substantially diamond-shaped grille opening 124 is formed. On the grille opening 124, as shown in Fig. 2, fin 125 which includes three blade portions is mounted. The fin 125 is, as shown in Fig. 7, mounted on the grille opening 124 by passing fastening members not shown in the drawings through the threaded holes 131 of two boss portions 130 which is formed in the vicinity of left lower side of the grille opening 124 of the outer member

100b from a back side of the outer member 100b.
[0029]
Further, in the outer member 100b, as shown in Fig. 7, two mounting holes 127, 128 are formed in a vertically spaced apart manner. One mounting hole 127 is formed in the vicinity of the grille opening 124 arranged inside the grille opening portion 126, and another mounting hole 128 is formed in an upper portion of the outer member 100b.
These two mounting holes 127, 128 are arranged in a state that the mounting hole 127 is aligned with positions of the mounting seat 103 of the fuel tank 11 and the mounting hole 128 is aligned with a position of the mounting seat 102 when the outer member 100b is assembled to the fuel tank 11. Further, by passing the fastening members 117 (see Fig. 2) through the mounting holes 127, 128 from the mounting holes 127, 128 side of the outer member 100b toward the fuel tank 11 side and engaging the fastening members 117 with the threaded holes 102a, 103a, the outer member 100b is mounted on portions arranged on a vehicle-body outside of the fuel tank 11. The mounting portions are generally referred to as outer mounting portions 119. Particularly, as shown in Fig. 2, the mounting portion on a mounting hole 127 side is referred to as an outer lower mounting portion 119a, and the mounting portion on the mounting hole 128 side is referred to as an outer upper mounting portion 119b.

Due to the shroud mounting structure of the motorcycle according to the embodiment of the present invention, in a state that the motorcycle 1 is viewed from the side thereof, the mounting portion 105 for mounting the front side of the fuel tank 11 on the main pipe 31 is arranged in a state that the mounting portion 105 is vertically sandwiched between the outer lower mounting portion 119a and the outer upper mounting portion 119b for mounting the outer member 100b on the fuel tank 11 and, at the same time, the outer lower mounting portion 119a and the outer upper mounting portion 119b are arranged behind the mounting portion 105 in the longitudinal direction of the vehicle body and hence, it is possible to effectively disperse the external force which is operated by the pressure of a wind which the shroud 100 receives from a front side thereof to the outer lower mounting portion 119a and the outer upper mounting portion 119b thus obtaining the shroud mounting structure which can withstand the wind pressure.
[0031]
Further, the inner mounting portion 118 for mounting the inner member 100a on the fuel tank 11 is also arranged in a state that the inner mounting portion 118 is vertically sandwiched between the outer lower mounting portion 119a and the outer upper mounting portion 119b in the same manner and hence, it is possible to prevent the shroud 100 from being

twisted at the inner mounting portion 118 due to the wind pressure from the front side of the vehicle.
[0032]
Further, the inner mounting portion 118 allows the fastening members 116 to pass therethrough from the front side to the rear side in the longitudinal direction of the vehicle body and allows the fastening members 116 to be fastened therein and hence, it is possible to maintain the external force which the vehicle receives due to the pressure of the wind coming toward the front side of the vehicle by a shearing force of the fastening members 116 such as bolts. Accordingly, it is possible to enhance the rigidity of the mounting portion.
Further, the outer member 100b is formed into a shape which is formed by notching the shroud surface until a portion between the outer lower mounting portion 119a and the outer upper mounting portion 119b and hence, it is possible to realize the reduction of weight of the shroud 100. Further, due to such a notched shape, it is possible to make it difficult to shift the shroud 100 from the groove portion lid.
[0033]
The outer member 100b of the shroud 100 arranges the outer lower mounting portion 119a in the inside of a grille opening portion 126 thereof and hence, by mounting a fin 125 on the grille opening portion 126, it is possible to conceal the outer lower mounting portion 119a with a blade portion of the fin

125. Due to such a constitution, the appearance of the motorcycle 1 can be enhanced.
[0034]
The fuel tank 11 forms the recessed portion lid in a portion thereof which is overlapped to the shroud 100 and a shroud surface of the shroud 100 and a surface of the fuel tank 11 are made substantially coplanar with each other thus imparting a feeling of integrity of the shroud and the fuel tank to shroud mounting structure of the motorcycle and allowing the occurrence of errors in a shape of the shroud.
Further, the inner member 100a and the outer member 100b which constitute the shroud 100 are mounted on the fuel tank 11 by fastening members 115, 116, 117 and hence, in mounting or dismounting the fuel tank 11, it is unnecessary to remove the shroud 100 thus facilitating the mounting and dismounting operations of the fuel tank 11 easily.
[0035]
Although the best mode for carrying out the present invention has been explained heretofore, the present invention is not limited to the above-described embodiment and various modifications and variations are conceivable based on the technical concept of the present invention.
In the mode for carrying out the present invention, the shroud 100 is constituted of two members consisting of the inner member 100a and the outer member 100b. However, the shroud

100 is not always necessary to be constituted of separate members but may be integrally formed of the inner member 100a and the outer member 100b. Further, the shroud 100 may be formed of three or more members. That is, the integral shroud
100 may include the inner mounting portion 104 which is mounted
on the fuel tank 11 from the inside of the vehicle body and
at least two outer mounting portions 102, 103 which are mounted
on the fuel tank 11 from the outside of the vehicle body, the
outer mounting portions 102, 103 sandwich the mounting portion
101 of the fuel tank 11 from above and below, and the outer
mounting portions 102, 103 may be arranged behind the mounting
portion 101 of the fuel tank 11.
