PROBLEM TO BE SOLVED: To provide an impact absorption member which can enhance impact absorption performance.SOLUTION: In a cylindrical impact absorption member 1, a cross section of the impact absorption member 1 is formed into a rectangular cylindrical shape, and a direction along the other end 12 from one end 11 of the impact absorption member 1 is set as an impact absorption direction L. A bead 15 in which a part of a sidewall part 13 being each rectangular side is recessed to the inside is formed at the impact absorption member 1 along the impact absorption direction L from one end 11 up to the other end 12, and a thickness of the sidewall part 13 is gradually thinned along the impact absorption direction L.SELECTED DRAWING: Figure 1
【課題】衝撃吸収性能を高めることができる衝撃吸収部材を提供する。【解決手段】筒型形状の衝撃吸収部材1であって、衝撃吸収部材1は、断面が矩形状の筒型形状であり、衝撃吸収部材1の一方端11から他方端12に沿った方向を、衝撃吸収方向Lとしており、衝撃吸収部材1には、一方端11から他方端12まで衝撃吸収方向Lに沿って、矩形状の各辺となる側壁部13の一部が内側に凹んだビード15が形成されており、側壁部13の肉厚は、衝撃吸収方向Lに沿って、徐々に薄くなっている。【選択図】図1
