Impact absorption performance is improved. In a frontal vehicle collision, an orthogonal cross-section of a crash box (50), taken orthogonally to the vehicle front-rear direction, deforms into a hexagonal shape. Due to this deformation of the orthogonal cross-section, new ridge lines (R11, R12, R13, R14) are formed at an upper face portion (52) and a lower face portion (54), running from the vicinity of both end portions in a vehicle width direction of vehicle rear end portions to the vicinity of both end portions in the vehicle width direction of respective join portions S. The strength of the crash box (50) in the vehicle front-rear direction increases due to the increased number of ridge lines in the vehicle front-rear direction (axial direction). Load generated during crushing of the crash box (50) in the vehicle front-rear direction therefore increases, as a result of which the energy absorption amount of the crash box (50) increases. Namely, the impact absorption performance of the crash box (50) is improved.
