To provide an impact absorbing member and impact absorbing device which can exhibit impact absorption performance sufficiently.SOLUTION: An impact absorbing device 1 includes a cylindrical side member 10extending in a vehicle longitudinal direction, and an impact absorbing member 20having a cylindrical main body part 21 extending in the vehicle longitudinal direction. A rear end part of the main body part 21 is inserted in a front end part of the side member 10. A pair of through holes are linearly formed on one side surface part and the other side surface part opposite to the one side surface part of a part in which the side member 10and the main body part 21 are overlapped. When a rod-like fastening member is inserted in the through hole, movement of the impact absorbing member 20to the side member 10is restricted. A support part which reduces an impact load applied on an inner circumferential surface of the through hole of the impact absorbing member 20upon receiving the impact load when the impact load is applied on the impact absorbing member 20is arranged in the side member 10or in the main body part 21.SELECTED DRAWING: Figure 2
【課題】衝撃吸収性能を充分に発揮させることができる衝撃吸収部材及び衝撃吸収装置を提供する。【解決手段】 衝撃吸収装置1は、車両前後方向に延びる筒状のサイドメンバー10Lと、車両前後方向に延びる筒状の本体部21を有する衝撃吸収部材20Lと、を備える。本体部21の後端部が、サイドメンバー10Lの前端部内へ挿入され、サイドメンバー10Lと本体部21とが重なった部分の一方の側面部及び前記一方の側面部に対向する他方の側面部に、同一直線上に一組の貫通孔が設けられていて、前記貫通孔に棒状の締結部材が挿入されることにより、サイドメンバー10Lに対する衝撃吸収部材20Lの車両前後方向への移動が規制される。衝撃吸収部材20Lに衝突荷重が印加されたとき、衝突荷重を受けて、衝撃吸収部材20Lの前記貫通孔の内周面に印加される衝突荷重を緩和する支持部が、サイドメンバー10L内又は本体部21内に設けられている。【選択図】図2
