A crash can with a cross-shaped cross section is provided between a side frame and a bumper beam. The crash can connects to an end portion of the side frame in a state where its four projecting portions are directed respectively in upper, lower, right and left directions. The bumper beam comprises a protruding portion which extends in the vehicle width direction. The right and left projecting portions are joined to a top face of the protruding portion and that the upper and lower projecting portions are joined to upper and lower faces of the protruding portion respectively. Plural beads are formed at the crash can at positions which avoid spot-joint positions. Accordingly, the impact energy can absorbed effectively by the crash can.
