To provide an impact absorption member which can control a buckling starting point and a deformation direction to keep a load substantially constant even when a member is long.SOLUTION: An impact absorption member has: a first structure part which starts buckling with an impact received from a tip and deforms along an impact direction; a second structure part which is connected to the first structure part, has buckling strength higher than that of the first structure part, and deforms along the impact direction; and a third structure part which is connected to the second structure part, has buckling strength higher than that of the second structure part, and forms a non-impact end.SELECTED DRAWING: Figure 1
【課題】部材が長尺の場合においても、座屈起点と変形方向を制御することで荷重を略一定に保つことができる衝撃吸収部材を提供する。【解決手段】衝撃吸収部材は、先端から受けた衝撃により座屈を開始し、衝撃方向に沿って変形する第1構造部と、第1構造部に連結し、第1構造部よりも座屈強度が高く衝撃方向に沿って変形する第2構造部と、第2構造部に連結し、第2構造部よりも座屈強度が高く反衝撃端を形成する第3構造部と、を有することを特徴とする衝撃吸収部材。【選択図】図1
