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). |
