PROBLEM TO BE SOLVED: To obtain a vehicle bumper structure having a pedestrian collision detection sensor which can favorably maintain sensing performance, in a vehicle having a curved bumper cover which wraps around to a rear side of the vehicle as progressing toward a corner part of an end part in a vehicle width direction.SOLUTION: A front bumper 12 has: a bumper RF14; an absorber 16 arranged outside the bumper RF14 in a vehicle fore-and-aft direction; a bumper cover 18 arranged outside the absorber 16 in the vehicle fore-and-aft direction; a pedestrian collision detection sensor 20 which is extensively arranged in a vehicle width direction between the bumper RF14 and the absorber 16, and outputs a signal according to a volume change of the inside of a pressure tube 22 whose tip side passes through a side part 14A of the bumper RF14; and an oscillation member 26 which is arranged so as to be oscillatory at an end part of the bumper RF14 in the vehicle width direction in the vehicle fore-and-aft direction, and crushes the pressure tube 22 between the side part 14A and itself by being crushed by the bumper cover 18, and oscillating to the inside in the vehicle fore-and-aft direction.SELECTED DRAWING: Figure 1
【課題】車両幅方向端部のコーナー部になるにつれて車両後方へ回り込む湾曲形状のバンパカバーを備えた車両において、センシング性能を良好に維持することができる歩行者衝突検知センサを備えた車両用バンパ構造を得る。【解決手段】フロントバンパ12は、バンパRF14と、バンパRF14の車両前後方向外側に配置されたアブソーバ16と、アブソーバ16の車両前後方向外側に配置されたバンパカバー18と、バンパRF14とアブソーバ16との間で車両幅方向に延在され且つ先端側がバンパRF14の側部14Aを通る圧力チューブ22の内部の体積変化に応じて信号を出力する歩行者衝突検知センサ20と、バンパRF14の車両幅方向端部に車両前後方向に揺動自在に設けられ、バンパカバー18に押圧されて車両前後方向内側に揺動することで、側部14Aとの間で圧力チューブ22を押し潰す揺動部材26と、を有する。【選択図】図1
