Abstract:
To provide a bumper reinforcement which can suppress a body of a vehicle from being locally pressed, by controlling a position in a vehicle width direction of a part thereof that is first folded and bent when a center-pole collison occurs.SOLUTION: A high-rigidity region 112 has rigidity higher than rigidities of a first reference rigidity region 111a and a second reference rigidity region 111b and is positioned at the center in a vehicle width direction of a main body part 110. The first reference rigidity region 111a is positioned at one side in the vehicle width direction with respect to the high rigidity region 112, and the second reference rigidity region 111b is positioned at the other side in the vehicle width direction with respect to the high rigidity region 112. A reinforcement member 120 overlaps with at least respective parts of the high rigidity region 112 and of the first reference rigidity region 111a across a first boundary position 113a so as to cross through the first boundary position 113a between the high rigidity region 112 and the first reference rigidity region 111a in the vehicle width direction.SELECTED DRAWING: Figure 4
