As shown in FIG. 1, the front fender body 16 is attached to the lower rear part so as to cover the front wheel 11 and a part of the front wheel 11 overlaps the front fender. As shown in FIG. 3, the inside of the mud flap 18 is located at the inner end of the front wheel 11 when the rod handle 14 is fully cut and the front wheel 11 is at the maximum steering angle position indicated by the chain double-dashed line. Extension line l
Is formed to extend to the position. As a result, even when the rod handle 14 is fully closed, it is possible to prevent splashing of mud on the engine 15.

As shown in FIGS. 1 and 3 to 6, the front fender main body 16 and the mud flap 18 are, as described above, partly overlapped with each other in the vehicle front-rear direction and the wind guide portion.
Twenty is formed. As shown in FIG. 5, the air guide portion 20 is
For example, the upper part and the lower part of the mud flap 18 that configures the air guide portion 20 are provided by being bent toward the front fender body 16 and contacting the front fender body 16 to form a recess having a box-shaped cross section. Further, the inlet 21 of the air guide portion 20 is opened inside the front fender device 22 including the front fender main body 16 and the mud flap 18. Further, the outlet 23 of the air guide portion 20 is opened on the rear side of the front fender device 22 toward the center of the vehicle as shown in FIGS. 4 and 6.
