To provide a vehicle impact absorption member which can set with a higher degree of freedom, a structure of a vehicle impact absorption member which can highly efficiently absorb impact energy.SOLUTION: An impact absorption member 30 is formed of a resin material. The impact absorption member 30 has a cylindrical main body part 31 and an intermediate wall part 32. The intermediate wall part 32 is arranged in an intermediate position of the main body part 31 in an axial line direction in the main body part 31, and extends in a direction intersecting with the axial line direction. The main body part 31 has a fracture part 35 which fractures when being buckled and deformed by an axial load. The fracture part 35 extends along a boundary portion between the main body part 31 and the intermediate wall part 32.SELECTED DRAWING: Figure 1

    【課題】効率の良い衝撃エネルギーの吸収が可能になる車両用衝撃吸収部材の構造を高い自由度で設定することのできる車両用衝撃部材を提供する。【解決手段】衝撃吸収部材30は、樹脂材料によって形成されている。衝撃吸収部材30は、筒状をなす本体部31と、中間壁部32とを有する。中間壁部32は、本体部31の内部における同本体部31の軸線方向の中間位置に設けられるとともに、軸線方向と交差する方向に延在する。本体部31は、軸荷重によって座屈変形した場合に破断する破断部35を有する。破断部35は、本体部31と中間壁部32との境界部分に沿って延設されている。【選択図】図1
