To provide a vehicle impact absorption member which enables improvement of impact energy absorption efficiency.SOLUTION: A vehicle impact absorption member 1 is provided between side frames 50 serving as vehicle framework parts and a reinforcement 60 and is configured to absorb an impact input from the reinforcement 60. The 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 is configured to compressively deform in an axial direction Y and absorb the impact. Each vehicle side attachment part 20 covers a rear end part 11 of the cylindrical part 10 as seen in the axial direction Y and is configured so that at least a part thereof fits into the side frame 50 to be attached to the vehicle framework part 50. The reinforcement side attachment part 30 is formed in a flange shape at a front end part 12 in the cylindrical part 10 as seen in the axial direction Y and is configured to be attached to the reinforcement 60.SELECTED DRAWING: Figure 1

    【課題】衝撃エネルギーの吸収効率を向上す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、車両骨格部としてのサイドフレーム50とレインフォース60との間に設けられて、レインフォース60から入力された衝撃を吸収するように構成されている。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ように構成されている。車両側取付部20は、筒部10における軸方向Yの後方端部11を覆うとともに、少なくとも一部がサイドフレーム50に嵌入して車両骨格部50に取り付けられるように構成されている。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にフランジ状に形成されて、レインフォース60に取り付けられるように構成されている。【選択図】図1
