Abstract

PURPOSE:To reinforce boss portions on a surface of a bumper side portion, by bringing reinforing ribs into abutment against a mount portion. CONSTITUTION:A bumper side portion 1a is formed with boss portions 3 projecting toward a fender 2 side. Reinforcing ribs 9 are integrally formed with the boss portions 3 and the side portion 1a in such a manner as to straddle the same. Burring sleeves projecting toward the boss portions 3 side are integrally formed with edge portions of screw holes 4a of a mount bracket 4. An impact force applied to the side portion 1a is dispersedly transmitted through the boss portions 3, reinforcing ribs 9, screws 5 and burring sleeves to the mount bracket 4. Therefore, there is no possibility that the impact force is centered at the boss portions 3.
