In order to absorb energy without increasing a reaction force to a pedestrian during a collision to a certain degree or more, a bumper absorber (20) is provided with: a first structure (21) having a mountain-shaped cross-sectional structure perpendicular to the Y direction; and a second structural body (22) having a shape capable of being simply compressed in the X direction, the first structural body (21) having a groove (21c) extending in the Y direction on the rear end surface (21b) thereof, the dimension (A) of the first structural body (21) in the X direction being larger than the dimension (A ') of the second structural body (22) in the X direction, and the density of the first structural body (21) and the second structural body (22), and the width (D) and depth (C) of the groove (22c) of the first structural body (21) being set within specific ranges.

    以吸收能量而不使在碰撞时向行人的反作用力大至一定程度以上为目的,保险杠吸能器(20)具备:第1结构体(21),其相对于Y方向垂直的截面结构为山形状;以及第2结构体(22),其为能够在X方向上被单纯压缩的形状,第1结构体(21)在其后端面(21b)具有沿Y方向延伸的槽(21c),第1结构体(21)的X方向上的尺寸(A)大于第2结构体(22)的X方向上的尺寸(A’),第1结构体(21)和第2结构体(22)的密度、以及第1结构体(21)的槽(22c)的宽度(D)和深度(C)被设定在特定范围内。
