To provide a vehicular impact absorber which can absorb impact with a simple structure.SOLUTION: A vehicular impact absorber having: a collision load inputting member 14 which is provided on at least one of a vehicle front part and a vehicle rear part, and to which a collision load is inputted; a cylindrical member 20 which is provided on a vehicle longitudinal direction inner side of the collision load inputting member 14, and of which an end on a vehicle longitudinal direction outer side is connected to the collision load inputting member 14 side; a support member 18 which so supports the cylindrical member 20 as to be slidable in the vehicle longitudinal direction between a storage position on the vehicle longitudinal direction inner side and an operation position on the vehicle longitudinal direction outer side; a gas generation part 24 which, when detecting or predicting collision of a vehicle, generates a gas in a space 19 surrounded by the cylindrical member 20 and the support member 18, and slides the cylindrical member 20 to the operation position; and a valve 28 which is provided on the support member 18, and discharges the gas to the exterior in the state that the cylindrical member 20 is moved to the operation position and when a gas pressure in the space 19 becomes higher than a prescribed pressure.SELECTED DRAWING: Figure 4

    【課題】簡易な構造で衝突を吸収することができる車両用衝撃吸収装置を提供する。【解決手段】車両前部及び車両後部の少なくとも一方に設けられ、衝突荷重が入力される衝突荷重入力部材14と、衝突荷重入力部材14の車両前後方向内側に設けられ、車両前後方向外側の端部が衝突荷重入力部材14側に接続された筒状部材20と、筒状部材20を車両前後方向内側の収納位置と車両前後方向外側の作動位置との間で車両前後方向に摺動可能に支持する支持部材18と、車両の衝突を検知又は予知した際に、筒状部材20と支持部材18とで囲まれた空間19内でガスを発生させて筒状部材20を作動位置へ摺動させるガス発生部24と、支持部材18に設けられ、筒状部材20が作動位置へ移動した状態で、かつ、空間19内のガス圧が所定の圧力よりも高くなった際に外部へガスを排気するバルブ28と、を有する。【選択図】図4
