PROBLEM TO BE SOLVED: To provide a shock absorbing structure capable of exhibiting an energy absorption characteristic of an energy absorbing member to the maximum even for either of offset collision and full lap collision even while simplifying a design work.SOLUTION: A shock absorbing structure includes: an energy absorbing member 20 fixed to the car body side and; a junction part 30 which, while setting a longitudinal direction along the back and forth direction of a vehicle, connects a base edge part 31a to the energy absorbing member, connects a tip part 31b to a bumper beam and, when a collision load is inputted to the car body side from the bumper beam side, applies a load to the energy absorbing member while being crushed in the longitudinal direction. The tip part of the junction part has such an inclined shape that, as proceeding from the width direction center side of the vehicle to the width direction outer side, a distance from the energy absorbing member is gradually decreased, such a gradual increasing region 70 that, as proceeding from the width direction center side of the vehicle to the width direction outer side, the width in a height direction of the vehicle is gradually increased and such a gradual decreasing region 71 that the width in the height direction of the vehicle is gradually decreased.

    【課題】設計作業を簡素化しつつも、オフセット衝突およびフルラップ衝突のいずれに対しても、エネルギ吸収部材のエネルギ吸収特性を最大限に発揮し得る衝撃吸収構造を提供する。【解決手段】車体側に固定されるエネルギ吸収部材20と、車両の前後方向に長手方向を沿わせた状態で、基端部31aがエネルギ吸収部材に接続されるとともに、先端部31bがバンパビームに接続され、バンパビーム側から車体側に衝突荷重が入力されると、長手方向に圧潰しながらエネルギ吸収部材に荷重を作用させる接合部30と、を備える。接合部の先端部は、車両の幅方向中央側から幅方向外側に向かうにしたがって、エネルギ吸収部材からの距離が漸減する傾斜形状であって、かつ、車両の幅方向中央側から幅方向外側に向かうにしたがって、車両の高さ方向の幅が漸増する漸増領域70、および、車両の高さ方向の幅が漸減する漸減領域71を備えている。【選択図】図4
