PROBLEM TO BE SOLVED: To enhance an energy absorption effect of metal gussets which obliquely connect a bumper beam and a bumper beam extension.SOLUTION: A pair of left and right metal gussets 14 that reinforce a connection part of a bumper beam 12 and a bumper beam extension 13 are constituted of: a first fixed part 14a to be fixed to an inner face in a longitudinal direction of the bumper beam 12; a second fixed part 14b to be fixed to an inner face in a vehicle width direction of the bumper beam extension 13; and an intermediate part 14c which obliquely connects the first fixed part 14a to the second fixed part 14b. This constitution allows the metal gussets 14 to easily secure a certain cross section across the whole length, so that energy absorption amounts of the metal gussets 14 when being bent and deformed can be increased at the initial time of a collision, and further the metal gussets 14 are buckled and at the same time fiber and resin of the bumper beam extension 13 are separated and broken at the later time of the collision, leading to a synergistic effect by which absorption amounts of collision energy are increased.SELECTED DRAWING: Figure 2

    【課題】 バンパービームおよびバンパービームエクステンションを斜めに接続する金属ガセットのエネルギー吸収効果を高める。【解決手段】 バンパービーム12およびバンパービームエクステンション13の接続部を補強する左右一対の金属ガセット14は、バンパービーム12の前後方向内面に固定される第1固定部14aと、バンパービームエクステンション13の車幅方向内面に固定される第2固定部14bと、第1固定部14aおよび第2固定部14bを斜めに接続する中間部14cとからなるので、金属ガセット14は全長に亙って一定断面の確保が容易になり、衝突初期に金属ガセット14が曲げ変形する際のエネルギー吸収量を増加させることができるだけでなく、衝突後期には金属ガセット14が座屈すると同時にバンパービームエクステンション13の繊維と樹脂とが分離して破壊し、その相乗効果で衝突エネルギーの吸収量が増加する。【選択図】 図2
