A vehicle bumper structure includes a pair of left and right crush cans, a bumper beam, an energy absorbing member and a bumper face. Each of the crush cans has an outside wall and an inside wall, the inside wall having higher longitudinal stiffness than the outside wall. When a full-wrap collision occurs at a speed below a specified speed limit, neither of the two crush cans crushes but the energy absorbing member and the bumper beam warp and absorb impact energy. When an offset collision occurs at a speed equal to or above the specified speed limit, on the other hand, one of the crush cans sufficiently crushes and absorbs impact energy in a reliable fashion. |
