PROBLEM TO BE SOLVED: To provide a vehicle bumper structure capable of absorbing collision energy by the deflection of an energy absorbing member and a bumper beam without crushing a pair of crush cans when full-wrap collision occurs at a speed not higher than a predetermined value, and absorbing the collision energy by reliably and sufficiently crushing the crush cans when an offset collision occurs at the speed higher than the predetermined value. SOLUTION: A vehicle bumper structure 3 includes a pair of crush cans 10, a bumper beam 20, an energy absorbing member 30 and a bumper face 35. Each of the crush cans 10 has an outside wall 17 and an inside wall 18, the inside wall having higher longitudinal stiffness than the outside wall. A plurality of brittle bead parts 17a extending in the vertical direction are formed only on the outside wall 17. The inside wall 18 has an extension part 18b extending forwardly in an inclined manner and connected to a rear surface of a front wall 24 of the bumper beam 20. A reinforcing bead part 18c extending in the longitudinal direction is formed in the extension part 18b. COPYRIGHT: (C)2008,JPO&INPIT
