PROBLEM TO BE SOLVED: To provide an energy absorption structure capable of inhibiting a broken energy absorption member made of fiber-reinforced resin from being clogged in a cover covering the energy absorption member and of suppressing an increase in a crush load and a decline in collision energy absorption amount.SOLUTION: An energy absorption structure includes: a cylindrical energy absorption member that is made of fiber-reinforced resin and is crushed in the axial direction to absorb collision energy when a load is input; a cylindrical cover covering the outer periphery of the energy absorption member; and a holding member for holding an end on the side opposite to the load input side of the energy absorption member. The holding member includes: an opening through which the crushed energy absorption member is made to pass; and a pointed portion for breaking the crushed energy absorption member and guiding at least part of the energy absorption member to the opening.SELECTED DRAWING: Figure 2
【課題】破壊された繊維強化樹脂製のエネルギ吸収部材が、エネルギ吸収部材を覆うカバー内で詰まることを抑制し、圧壊荷重の増大や衝突エネルギ吸収量の低下を抑制可能なエネルギ吸収構造体を提供する。【解決手段】エネルギ吸収構造体は、荷重入力時に軸方向に圧壊して衝突エネルギを吸収する繊維強化樹脂製の筒状のエネルギ吸収部材と、エネルギ吸収部材の外周を覆う筒状のカバーと、エネルギ吸収部材の荷重入力側とは反対側の端部が保持される保持部材と、を備え、保持部材は、圧壊したエネルギ吸収部材を通過させる開口部を有するとともに、圧壊したエネルギ吸収部材を破断して当該エネルギ吸収部材の少なくとも一部を開口部に導く尖頭部を有する。【選択図】図2
