PROBLEM TO BE SOLVED: To provide a shock absorbing structure which can suitably alleviate a shock applied to a mating vehicle, and can surely operate an occupant constriction device arranged at the mating vehicle immediately after the generation of the shock.SOLUTION: An energy absorbing body 7 is arranged between an UP bracket 6 and an FUP bar 5, connects them, supports the FUP bar 5 from a backside, and absorbs a shock by being crushed between the FUP bar 5 and the UP bracket 6 at a collision of a vehicle. A movement regulation part 8 regulates the rearward movement of the FUP bar 5 to the UP bracket 6. Furthermore, the movement regulation part 8 includes a regulation release part 23 which maintains the movement regulation of the FUP bar 5 without being fractured until an input load reaches a prescribed critical load, is fractured by the reach of the input load to the critical load, and releases the movement regulation of the FUP bar 5.

    【課題】相手車両に与える衝撃を好適に緩和するとともに、相手車両が装備する乗員拘束装置を衝突発生の直後に確実に作動させることが可能な車両の衝撃吸収構造の提供。【解決手段】エネルギ吸収体7は、UPブラケット6とFUPバー5との間に配置されて両者を連結し、FUPバー5を後方から支持するとともに、車両衝突時にFUPバー5とUPブラケット6との間で圧潰することによって衝撃を吸収する。移動規制機構8は、UPブラケット6に対するFUPバー5の後方への移動を規制する。また、移動規制機構8は、入力する荷重が所定の臨界荷重に達するまでの間は破断せずにFUPバー5の移動規制を維持し、入力する荷重が臨界荷重に達することにより破断してFUPバー5の移動規制を解除する規制解除部23を含む。【選択図】図5
