PROBLEM TO BE SOLVED: To provide a vehicular bumper beam which is light-weight, has excellent productivity, and exhibits excellent energy absorption performance in the case of collisions from different directions.SOLUTION: A vehicular bumper beam 10 is a bumper beam 10 which is arranged near the front end part or the rear end part of a vehicle body, extends in a vehicle width direction, and has a hollow structure. It has a separator 13 which is arranged between an outer surface wall 14 constituting a collision surface of the bumper beam 10 and an inner surface wall 19 facing the outer surface wall 14 and extends in the vehicle width direction.The separator 13 has reinforcement parts 25 formed in it, of which positions change toward an upper or lower direction. Thus, the bumper beam is light-weight and has excellent productivity, while having little deformation in its cross-sectional shape in the case of collisions from different directions and being capable of absorbing collision energy efficiently.

    【課題】軽量で生産性に優れ、且つ異なる方向からの衝突に対して優れたエネルギー吸収性能を発揮する車両用バンパビームを提供する。【解決手段】本発明の車両用バンパビーム10は、車体の前方端部若しくは後方端部の近傍に配設されて車幅方向に延在する中空構造のバンパビーム10であって、バンパビーム10の衝突面を構成する外面壁14と外面壁14に対向する内面壁19との間に架設されて車幅方向に延在するセパレータ13を有し、セパレータ13には、車幅方向で上方または下方に変位する補強部25が形成される。これにより、バンパビームは、軽量で生産性に優れ、且つ異なる方向からの衝突に対して横断面形状の崩れが少なく、衝突エネルギーを効率的に吸収することができる。【選択図】図2
