Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin molded fender for a vehicle, which is integrally molded with a synthetic resin . 2. Description of the Related Art In a vehicle such as a motorcycle, for example, many synthetic resin molded parts such as fenders for covering front and rear wheels are used to reduce the weight of a vehicle body. By the way, especially in the case of off-road motorcycles traveling on uneven terrain, a large amount of mud adheres to the back of the fender when traveling and the weight of the fender increases, so the thickness of the fender mounting part is increased and the rigidity is increased. The thickness of the tip of the fender is reduced in order to prevent the fender from being damaged by the weight of the mud and to reduce the weight of the fender itself. However, if the thickness of the fender mounting portion is increased, the thickness of the entire fender mounting portion is increased. Could not be expected to be lighter. Therefore, it is conceivable to increase the rigidity by forming a rib inside the fender without increasing the thickness of the fender. However, when such a rib is provided, there is an adverse effect that when the wheel of the motorcycle comes closest to the fender, the wheel interferes with the rib, and mud attached to the wheel accumulates on the rib. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems.

A rear fender 17 is provided to cover the upper part of the seat and extend rearward, and both right and left sides of the seat 16 are covered by side covers. FIGS. 2 and 3 are a left side view and a plan view of the rear fender 17, respectively, and FIG. 4 (a) and FIG.
(b) is a cross-sectional view taken along the line IVa-IVa and IVb-IVb in FIG. 2, and shows one embodiment of the present invention. The rear fender 17 is provided with the front fender 6 and the side cover 18.
It is integrally molded with synthetic resin with parts such as. The rear fender 17 has a design in which the front half 17F is covered with the seat 16 and the side cover 18, and the rear half 17R is exposed to the outside and extends rearward. A gate 21 serving as an inlet for pouring a synthetic resin material into a mold at the time of molding the rear fender 17 is provided at the center of the outer surface of the front half 17F in the vehicle width direction. Further, the pedestals 22 and 23 provided before and after the front half portion 17F are screwed to the vehicle body frame 2, so that the entire rear fender 17 is fixed to the vehicle body frame 2. As shown in FIG. 1, the rear half portion 17R extends in the circumferential direction at the left and right shoulders and bends linearly at the corners 24A,
24B and 24C. For this reason, the cross-sectional shape of the rear half portion 17R has a substantially trapezoidal cross section as shown in FIG. 4 (b). A pair of left and right hollow portions 25 are formed near the front lower edge of the rear half portion 17R, and by increasing the thickness t of this portion, it is easy to handle, and the rear wheel of the motorcycle 1 is formed.
