VEHICLE IMPACT ABSORBING STRUCTURE

To suppress the deformation of a vehicle body upon a collision while preventing an increase in a rear overhang amount.SOLUTION: An impact absorbing structure of a vehicle 1 is equipped with a bumper beam 2 that extends in a vehicle width direction at a position separated to a vehicle rear side from a vehicle body 10, and a pair of supporting members 3 supporting the bumper beam 2 on both sides in the vehicle width direction. In the bumper beam 2, a cross-section orthogonal to the vehicle width direction is formed to be an opened cross-section equipped with an upper recessed portion 22 recessed from a rear surface 2rf facing the vehicle rear side toward a vehicle front side, a lower recessed portion 23 located below the upper side recessed portion 22 and recessed from the rear surface 2rf toward the vehicle front side, and an intermediate rear surface portion 25 located between the upper recessed portion 22 and the lower recessed portion 23 and having the rear surface 2rf. The supporting member 3 supports an upper part of the bumper beam 2 rather than the lower recessed portion 23.SELECTED DRAWING: Figure 1 【課題】リアオーバーハング量の増大を防ぎつつ、衝突時の車体の変形を抑制する。【解決手段】車両１の衝撃吸収構造は、車体１０から車両後方に離隔した位置において、車幅方向に沿って延びるバンパビーム２と、車幅方向両側でバンパビーム２を支持する一対の支持部材３と、を備え、バンパビーム２は、車幅方向に直交する断面が、車両後方を向く後面２ｒｆから車両前方に向かって凹む上側凹部２２と上側凹部２２よりも下方に位置して後面２ｒｆから車両前方に向かって凹む下側凹部２３と上側凹部２２及び下側凹部２３の間に位置して後面２ｒｆを有する中間後面部２５とを備える開断面となるように形成され、支持部材３は、下側凹部２３よりもバンパビーム２の上部を支持する。【選択図】図１
