The invention provides a bumper energy absorber. In order to absorb energy during a collision without increasing a reaction force to a pedestrian to a certain degree or more, a bumper absorber (20) is provided with: a trunk part (21) which extends in the X direction and is purely compressed in the X direction when subjected to an impact; and a trunk section (22) that branches from the trunk section (21) toward the rear of the vehicle body, in which a branch section (23) of the trunk section (22) that branches from the trunk section (21) is provided with a fracture-inducing section (24) that induces a fracture of the trunk section (21) and the trunk section (22) due to an impact.
本发明提供一种保险杠吸能器。本发明的目的在于,在碰撞时吸收能量而不使向行人的反作用力大至一定程度以上,该保险杠吸能器(20)具有:主干部(21),其沿X方向延伸,并受到冲击而在X方向上被单纯压缩;以及枝干部(22),其从主干部(21)向车身的后方分支,在枝干部(22)的与主干部(21)分支的分支部分(23)设有断裂引发部(24),该断裂引发部(24)引发因冲击而产生的主干部(21)与枝干部(22)的断裂。
