To improve the absorption efficiency of impact energy while suppressing size enlargement.SOLUTION: An impact absorption structure 10 comprises tension load receiving members 18 which are fractured by receiving tension load by load from a compression load receiving member 15. The tension load receiving members 18 are supported by a suspension support portion 13 while the tension load receiving members 18 are arranged at intervals in a moving direction of the compression load receiving member 15. The tension load receiving members 18 are sequentially fractured by receiving the tension loads by the loads from the compression load receiving member 15, so that impact energy is sequentially absorbed. The absorption efficiency of the impact energy can be therefore enhanced as a whole without enlarging sizes of the tension load receiving members 18.SELECTED DRAWING: Figure 1
【課題】大型化を抑制しつつも、衝撃エネルギーの吸収効率を向上させること。【解決手段】衝撃吸収構造体10は、圧縮荷重受け部材15からの荷重により引張荷重を受けて破壊される引張荷重受け部材18を備えている。引張荷重受け部材18は、圧縮荷重受け部材15の移動方向に間隔をあけて複数配置された状態で懸架支持部13に支持されている。圧縮荷重受け部材15からの荷重により各引張荷重受け部材18が引張荷重を受けて次々に破壊されることにより、衝撃エネルギーが次々に吸収される。したがって、各引張荷重受け部材18それぞれの体格を大きくすること無く、全体的な衝撃エネルギーの吸収効率が高められる。【選択図】図1
