To provide a vehicle impact absorption member which enables improvement of impact energy absorption efficiency and can achieve weight saving of a bumper frame and low costs.SOLUTION: A vehicle impact absorption member 1 has cylindrical parts 10, vehicle side attachment parts 20, and reinforcement side attachment parts 30. Each cylindrical part 10 forms a cylindrical shape and compressively deforms in an axial direction Y to absorb an impact. Each vehicle side attachment part 20 is formed in a flange shape at a rear side part 11 in the cylindrical part 10 as seen in the axial direction Y to be attached to a vehicle framework part 50. The reinforcement side attachment part 30 covers a front end part 12 in the cylindrical part 10 as seen in the axial direction Y and is attached to a reinforcement 60. The reinforcement side attachment parts 30 sandwich a part of the reinforcement 60 when attached to the reinforcement 60 and at least parts thereof are located at a position which is flush with a front surface 61 of the reinforcement 60 or at a position Y2 in front of the reinforcement 60.SELECTED DRAWING: Figure 1

    【課題】衝突エネルギーの吸収効率を向上できるとともに、バンパ骨格の軽量化や低コスト化を図ることができる車両用衝撃吸収部材を提供すること。【解決手段】車両用衝撃吸収部材1は、筒部10、車両側取付部20、レインフォース側取付部30を有する。筒部10は、筒状を成すとともに軸方向Yに圧縮変形して衝撃を吸収する。車両側取付部20は、筒部10における軸方向Yの後方側部11にフランジ状に形成されて、車両骨格部50に取り付けられる。レインフォース側取付部30は、筒部10における軸方向Yの前方端部12を覆うとともに、レインフォース60に取り付けられる。レインフォース側取付部30は、レインフォース60に取り付けられた状態において、レインフォース60の一部を挟み込むとともに、少なくとも一部がレインフォース60の前面61と面一の位置又はレインフォース60よりも前方Y2の位置に位置する。【選択図】図1
