Title: Mud guard for vehicle
Inventor: HARAIKAWA TOSHIKATSU
IPC: B62D25/18
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent a splash by decreasing kinetic energy of water, mud or the like colliding against an inner end face of a mud guard as well as to enhance working efficiency of production and reduce a cost.
