To properly detect a collision of a collision body with a vehicle even when a person's back surface collides with the vehicle.SOLUTION: A collision detecting device comprises: a bumper beam 20 which extends in a vehicle width direction; an absorber 30 which is arranged next to the vehicle front side of the bumper beam 20 and extending in the vehicle width direction; a collision detection sensor 40 which includes a pressure tube 42 extending in the vehicle width direction and held by the absorber 30, and which outputs a signal in line with the change in pressure of the pressure tube 42; a tube holding part 32 which constitutes a part of a back end of the absorber 30, which is opened to the rear side of the vehicle, and which has a groove part for holding the pressure tube 42; a deformed space part 31 which constitutes a part of the back end of the absorber 30, which is provided in an upper part of the tube holding part 32, which is opened to the rear side of the vehicle, and which is deformed by a pressing force against the absorber 30; and an absorber support member 50 which is provided in a clearance between the absorber 30 and a front panel 22.SELECTED DRAWING: Figure 2
【課題】人が背面から車両に衝突した場合を含め、良好に衝突体の車両への衝突を検知する。【解決手段】車幅方向に延在されたバンパビーム20と、バンパビーム20の車両前側に隣接して配置され、車幅方向に延在されたアブソーバ30と、車幅方向に延在され且つアブソーバ30に保持された圧力チューブ42を含んで構成され、圧力チューブ42の圧力変化に応じた信号を出力する衝突検知センサ40と、アブソーバ30の後端部の一部を構成し、車両後側へ開放され、且つ、圧力チューブ42を保持する溝部を有するチューブ保持部32と、アブソーバ30の後端部の一部を構成し、チューブ保持部32の上部に設けられ、車両後側へ開放され、且つ、アブソーバ30への押圧力により変形する変形空間部31と、アブソーバ30とフロントパネル22との間隙に設けられたアブソーバ支持部材50と、を備える。【選択図】図2
