Abstract

PROBLEM TO BE SOLVED: To easily attach/detach a seat cowl in a seat mounting structure of a motorcycle without adversely affecting the mounting part of a rear fender on a motorcycle body, and to sufficiently secure the mounting rigidity of the seat cowl by mounting the seat cowl on the rear fender without individually mounting the rear fender and the seat cowl to the motorcycle body (back stay), and without jointly tightening the seat cowl and the rear fender to the motorcycle frame. SOLUTION: In a motorcycle in which a rear fender 14 is installed so as to cover the lower surface side of seats 11, 12 from the lower side, and a seat cowl 13 is installed so as to cover most of the rear fender 14 sidewise from the periphery of the seats 11, 12, the seat cowl 13 is mounted on the rear fender 14 irrespective of a motorcycle frame 25 in the vicinity of a mounting part of the rear fender 14 on the motorcycle frame 25 in the rear fender 14 mounted on the motorcycle frame 25.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a seat cowl to a vehicle body to cover a periphery of a seat in a motorcycle.

[0002]

2. Description of the Related Art In a motorcycle, a rear fender is provided with a pair of left and right rear fenders so as to cover a seat mounted on a pair of left and right seat rails at a rear upper portion of a vehicle body from below. A seat cowl is installed between the back stays, and further covers the seat rails, the back stays, and the rear fender so as to cover most of the seat rails. The fender is usually attached to the back stay of the body frame in a state where the fenders are fastened together.

[0003]

In the conventional motorcycle seat cowl mounting structure described above, the seat cowl and the rear fender are jointly fastened to the back stay, so that both can be simultaneously mounted during the mounting operation. A troublesome work such as positioning and attaching to the back stay is required, and in addition, when removing only the seat cowl, there is an inconvenience that the attachment portion of the rear fender is also removed at the same time.

On the other hand, if the rear fender and the seat cowl are to be individually mounted on the backstay without being fastened together, it is necessary to form many mounting portions for the backstay. The work of attaching and detaching the rear fender and seat cowl to and from such many attachment parts becomes complicated and troublesome, while attaching the seat cowl to the rear fender attached to the back stay, The mounting rigidity of the seat cowl will necessarily decrease.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described problems. More specifically, the present invention relates to a seat cowl mounting structure for a motorcycle, and a vehicle body frame (backstay).
By attaching the seat cowl to the rear fender without separately attaching the rear fender and the seat cowl to each other, and without fastening the seat cowl and the rear fender to the body frame, The seat cowl can be easily attached and detached without affecting the mounting portion of the seat cowl, and the mounting rigidity of the seat cowl at that time can be sufficiently ensured.

[0006]

According to the present invention, in order to solve the above-mentioned problems, a rear fender is provided so as to cover the lower surface of the seat from below, as described in claim 1 above. In a motorcycle in which a seat cowl is installed so as to cover most of the rear fender from the side of the seat from the side, the rear fender is attached to the body frame with respect to the rear fender attached to the body frame. The seat cowl is attached to the rear fender irrespective of the body frame near the section.

Further, in the motorcycle seat cowl mounting structure according to the first aspect of the present invention, the rear fender is provided at an appropriate position of a portion which protrudes outward from both sides of the rear fender as described in the second aspect. The seat cowl mounting part is formed on the upper side of the seat cowl mounting part of the rear fender. The seat cowl is attached to the rear fender by fixing the both while the cowl fixing portion is placed.

Further, in the motorcycle seat cowl mounting structure according to the second aspect, the third aspect is provided.
As described in, the rib protruding upward along the edge of the portion protruding outward of the rear fender and in the portion of the seat cowl attachment portion so as to bypass the edge and the seat cowl attachment portion. And a rib protruding upward is formed on a fixing portion of the seat cowl placed on the seat cowl mounting portion of the rear fender along an extending direction of the fixing portion. Things.
