To prevent increase in the dynamic bending angle of leg parts of a human body while restricting the intrusion of the leg parts of the human body under a cover when a collision accident occurs, and improve the safety while restricting the occurrence of obstruction such as ligament strain.

A support member 15 projected from a car body and abutting on a lower part of a bumper cover 3 is provided in a back surface of the bumper cover 3 so that the deformation quantity of the bumper cover 3 when a collision accident occurs can be regulated by the support member 5. Even if leg pars of a human body are intruding under the cover 3, since the deformation quantity of the cover 3 is regulated by the support member 5, intrusion quantity of the leg parts is restricted.
