To provide an impact absorption member whose size and mass can be made smaller than before.SOLUTION: An impact absorption member 30, which absorbs impact at the time of collision of a vehicle, is equipped with a plurality of impact absorption cells 31 mounted on a frame 40 of the vehicle with intervals. The impact absorption cells 31 are configured so as to receive impact loads with polygonal tube bodies 310 for receiving the impact loads with side surfaces thereof, by getting crushed in a direction of the collision loads while broadening in a direction crossing the direction of the impact loads. A dimension S of the interval between the adjacent impact absorption cells is set to a dimension at which the impact absorption cells 31 do not interfere with each other when broadening in the direction crossing the direction of the impact loads.SELECTED DRAWING: Figure 2

    【課題】衝撃吸収部材のサイズ、及び質量を従来よりも小さくできるようにすることである。【解決手段】車両衝突時の衝撃を吸収する衝撃吸収部材30であって、車両のフレーム40に間隙をおいて取付けられた複数の衝撃吸収用セル31を備えており、衝撃吸収用セル31は、側面で衝突荷重を受ける多角筒体310で、衝突荷重の方向に対して交差する方向に広がりながら、衝突荷重の方向に潰れることで、衝突荷重を吸収する構成であり、隣り合う衝撃吸収用セル間の間隔寸法Sは、各々の衝撃吸収用セル31が衝突荷重の方向に対して交差する方向に広がる際、互いに干渉しない寸法に設定されている。【選択図】図2
