PROBLEM TO BE SOLVED: To provide a shock absorption structure capable of setting a plurality of loads necessary for destruction, and absorbing impact energy in a state that the loads necessary for destruction is constant or increased to a displacement amount.SOLUTION: A shock absorption structure 9 includes an energy absorbing member 6 composed of a composite material having the cylindrical shape and having a plurality of layers in a radial direction, and absorbing impact energy while advancing interlayer destruction in a direction of a center shaft by a first load, and a pressing member 7 including a main body 7a having rigidity higher than the energy absorbing member, and absorbing impact energy while gradually destroyed in accordance with increase of the load necessary for destruction, when receiving the load higher than the first load, connected to one end in the center shaft direction, of the energy absorbing member, and pressing the energy absorbing member by receiving the load from the external.
【課題】破壊に要する荷重を複数設定可能とするとともに、破壊に要する荷重が変位量に対して、一定、または、増加して衝撃エネルギを吸収する。【解決手段】衝撃吸収構造9は、円筒形状であるとともに径方向に複数の層を有する複合材料で形成され、第1荷重で中心軸方向に層間破壊が進み、衝撃エネルギを吸収するエネルギ吸収部材6と、エネルギ吸収部材よりも剛性が高く、第1荷重よりも大きい荷重を受けると、破壊に要する荷重が増加するにつれて徐々に破壊されつつ衝撃エネルギを吸収する本体7aを有し、エネルギ吸収部材の中心軸方向の一端に連結され、外部からの荷重を受けてエネルギ吸収部材を押圧する押圧部材7と、を備える。【選択図】図2
