PROBLEM TO BE SOLVED: To exhibit stable impact absorbing performance regardless of the input direction of an impact load to be input, while reducing the weight of a bumper beam extension.SOLUTION: Because a bumper beam extension 18 arranged between a vehicle body frame 14 and a bumper beam 19 is FRP-made, weight reduction compared with a steel-plate-made bumper beam extension is achieved. And, as the bumper beam extension 18 comprises integrally a main impact absorbing part 18a on an inner side in the vehicular width direction and sub impact absorbing parts 18b, 18c on an outer side in the vehicular width direction, and the main impact absorbing part 18a is arranged along the front-and-rear direction and the sub impact absorbing parts 18b, 18c are arranged so that the outer side in the front-and-rear direction is inclined to the outer side in the vehicular width direction, then, an impact load of a head-on collision or a rear end collision is received in the axial line direction of the main impact absorbing part 18a, to exhibit sufficient impact absorbing performance, and an impact load of an oblique collision is received in the axial direction of the sub impact absorbing parts 18b, 18c, to exhibit sufficient impact absorbing performance. |
