The invention according to claim 1 is configured such that the cover member includes a rear fender disposed at the lower portion of the seat rail and a rear cowl disposed on both sides of the seat rail, and the left and right sides of the rear cowl are bulged outward from the vehicle body, The space itself enclosed by these rear cowls and rear fenders is used as a storage room, and the seat rail is composed of a single rail that passes through the center of the vehicle width. By this rail, the storage room is divided into left and right parts, and the seat is opened. Since the articles can be taken in and out of the storage room, the storage room is only divided into two by one seat rail passing through the center of the vehicle width, and a storage room with a large storage space can be provided on both sides of the seat rail. Moreover, the appearance of the storage room is good.
[0029]
According to the first aspect of the present invention, the rear fender that covers the upper portion of the rear wheel is configured by the cover member comprising the rear fender disposed at the lower portion of the seat rail and the rear cowls disposed on both sides of the seat rail. Since it also serves as the bottom of the member, the storage chamber can be made up of a small number of members and a simple structure.
[0030]
According to a second aspect of the present invention, a rear cover is formed by extending a side cover made of a separate member forward from the front portion of the rear cowl and bending the lower portion of the side cover to the center of the vehicle width so as to also serve as a part of the rear fender. Since the side cover that covers the vehicle body frame in front of the vehicle also serves as the front portion of the rear fender, the rear fender does not need to extend the front portion, and the rear fender can be reduced in size and weight.
