PROBLEM TO BE SOLVED: To allow a crash can to effectively absorb impact energy by properly transmitting a load applied to a bumper to the crash can. SOLUTION: The crash can 3 with an approximately cross-shaped cross section is provided between a side frame 1 and a bumper beam 2. The crash can 3 is connected to the end part of the side frame 1 in a state where its four projecting parts 3a, 3a, 3b, 3b are directed in upper, lower, right and left directions of a vehicle. The upper and lower projecting parts 3a, 3a of the crash can 3 are projected. The bumper beam 2 includes a projecting strip part 33 extending in the vehicle width direction. The right and left projecting parts 3b, 3b of the crash can 3 are joined to a top face 32a of the projecting strip part 33 respectively, and the upper and lower projecting parts 3a, 3a of the crash can 3 are joined to the upper and lower surfaces 32b, 32b of the projecting strip part 33 respectively. A plurality of beads 56 are formed on the crash can 3, avoiding a spot welded joint part S. COPYRIGHT: (C)2010,JPO&INPIT
