A shock absorbing member that absorbs shock by crushing in the axial direction, the shock absorbing member having a cylindrical shape extending in the axial direction, when a cross-section perpendicular to the axial direction of the impact absorbing member is defined as a first cross-section and a cross-section defined by extension lines of a plurality of sides in the first cross-section is defined as a second cross-section, the second cross-section is a polygon. The first cross-section includes a common apex that shares an apex with the second cross-section, and a groove positioned at a position corresponding to the apex of the second cross-section, and at least one interior angle of the apex of the first cross-section is 100 DEG or more.
一种冲击吸收构件,其通过轴向的压溃来吸收冲击,其中,上述冲击吸收构件具有沿着上述轴向延伸的筒形形状,在将上述冲击吸收构件的与上述轴向垂直的截面设为第1截面并将由上述第1截面中的多个边的延长线限定的截面设为第2截面的情况下,上述第2截面是多边形,上述第1截面包括与上述第2截面共有顶点的共有顶点和位于与上述第2截面的顶点对应的位置的凹槽,上述第1截面的顶点的至少一个内角为100°以上。
