PROBLEM TO BE SOLVED: To obtain a bumper structure favorable in space efficiency.SOLUTION: In a front bumper 12, an attachment 70 is extended to the outside of a vehicle width direction from an absorber 40, arranged adjacent to a vehicle front side of a pressure tube side protruded part 56B of a pressure tube 52, and protruded to the outside of the vehicle width direction with respect to the pressure tube side protruded part 56B. Then, when a corner part of a vehicle 10 collides with a pedestrian, a bumper cover 30 is deformed to a vehicle rear side, and presses the attachment 70 to the vehicle rear side. Therefore, the attachment 70 is bent and deformed to the vehicle rear side with a bend starting point 76 as a starting point, presses the pressure tube side protruded part 56B to the vehicle rear side, and the pressure tube side protruded part 56B is bent and deformed with an angular part 29A of a bumper RF20 as a starting point. Accordingly, since it is not necessary to arrange a spacer for compression-deforming a chamber member such as that in a conventional technology at a rear surface of the bumper cover 30, a bumper structure favorable in space efficiency can be obtained.
【課題】スペース効率の良いバンパ構造を実現する。【解決手段】フロントバンパ12では、アタッチメント70が、アブソーバ40から車幅方向外側へ延設されると共に、圧力チューブ52の圧力チューブ側突出部56Bの車両前側に隣接して配置され、圧力チューブ側突出部56Bに対して車幅方向外側へ突出されている。そして、車両10のコーナー部が歩行者に衝突すると、バンパカバー30が車両後側へ変形してアタッチメント70を車両後側へ押圧する。このため、アタッチメント70が、曲げ起点部76を起点として車両後側へ曲げ変形し、圧力チューブ側突出部56Bを車両後側へ押圧して、圧力チューブ側突出部56BがバンパRF20の角部29Aを起点に曲げ変形する。したがって、従来技術のようなチャンバ部材を圧縮変形させるためのスペーサをバンパカバー30の裏面に配置する必要がなくなるため、スペース効率の良いバンパ構造を実現できる。【選択図】図1
