This constitutes a wide fender structure provided with a mud damming portion for preventing protrusion. More specifically, the reinforcing portion is a thick portion formed in the load region of the applied load, and the reinforcing portion is a rib integrally formed so as to protrude toward the tire in the load region of the applied load. There is a group, wherein the rib group is composed of a plurality of ribs arranged at appropriate intervals from the body side panel side, and the height of the ribs increases toward the outer side.

Further, the mud damming portion comprises a curled fender portion disposed over a side surface of the tire, and the curled fender portion forms an R surface on the tire side. At the lower end of the curled fender portion, a curved portion having a curvature smaller than the curvature of the R surface is formed, and the wide fender is formed of an FRP (fiber) formed by an SMC (sheet molding compound) compression molding method. (Reinforce plastic).

Since the wide fender according to the present invention is an integrally molded product made of FRP by the SMC compression molding method, the assembling operation is easy and the assembling quality is stable. In addition, it is lightweight, does not rust, and hardly undergoes thermal deformation due to FRP. Further, the wide fender according to the present invention has a reinforcing portion formed in the load region of the applied load, and has sufficient rigidity.
