In a front bumper (10), a collision load from an impactor (I) is propagated to a propagation area (A1) between a first slope line (SL1) and a second slope line (SL2) inclined at an angle of 30° in a vehicle width direction about a reference normal (NL) passing a touching intersection (P1), in which an outer end (20A) of vehicle width direction of a bumper RF (20) is disposed in an area (A2) between the reference normal (NL) and the first slope line (SL1). Therefore, the collision load is conveyed to an absorber side part (30S) and the bumper RF (20) disposed inside the area (A2), thereby crushing a pressure tube (52) by the absorber side part (30S) and the bumper RF (20). Accordingly, even if the outer end (20A) of vehicle width direction of the bumper RF (20) is disposed in an inner side of vehicle width direction which is more inward than a front and rear reference line (CL), collision of the impactor (I) disposed on the front and rear reference line (CL) can be detected by a pedestrian collision detection sensor (50).

    프론트 범퍼(10)에서는, 임팩터(I)로부터의 충돌 하중이 맞닿음 교점(P1)을 통과하는 기준 법선(NL)에 대하여 차 폭 방향으로 30°경사진 제 1 경사선(SL1)과 제 2 경사선(SL2)과의 사이의 전파 에어리어(A1)를 전파한다. 여기에서, 범퍼 RF(20)의 차 폭 방향 외측단(20A)이, 기준 법선(NL)과 제 1 경사선(SL1)과의 사이의 에어리어(A2) 내에 배치되어 있다. 이 때문에, 충돌 하중이, 에어리어(A2) 내에 배치된 업소버 사이드부(30S) 및 범퍼 RF(20)로 전달되어, 압력 튜브(52)가, 업소버 사이드부(30S) 및 범퍼 RF(20)에 의해 눌려 찌그러진다. 이것에 의해, 범퍼 RF(20)의 차 폭 방향 외측단(20A)을 전후 기준선(CL)보다 차 폭 방향 내측에 배치한 경우여도, 전후 기준선(CL) 상에 배치된 임팩터(I)의 충돌을 보행자 충돌 검지 센서(50)에 의해 검지할 수 있다.
