Vehicle-body structure of vehicle

A vehicle-body structure of a vehicle, comprising:

• a pair of front side frames extending in a vehicle longitudinal direction and provided at both sides of the vehicle;
• a pair of crash cans provided at front end portions of the front side frames;
• and
• a bumper reinforcement provided to extend in a vehicle width direction between front end portions of the pair of crash cans such that a bending load is applied to the bumper reinforcement supported by the pair of crash cans at both side ends thereof in a vehicle collision,
• wherein said bumper reinforcement comprises:
• a first panel member having a U-shaped cross section, the first panel member including an upper face portion and a lower face portion, a vertical wall portion, and flange portions, the upper and lower face portions being respectively configured to continuously extend flatly in the vehicle width direction over an entire width, in the vehicle width direction, of the bumper reinforcement;
• and
• a second panel member formed substantially in a flat-plate shape, the second panel member being arranged on a vehicle forward side which is opposite side to a vehicle compartment relative to the first panel member and joined to the flange portions of the first panel member so as to form a closed cross section extending in the vehicle width direction together with the first panel member,
• wherein said first panel member includes step portions respectively formed at the upper face portion and the lower face portion, the step portion formed at the upper face portion being configured to slant rearward and downward in a side view and continuously extend flatly in the vehicle width direction, the step portion formed at the lower face portion being configured to slant rearward and upward in the side view and continuously extend flatly in the vehicle width direction, and a distance, in the vehicle longitudinal direction, of the step potions of the first panel member from said second panel member is configured such that the distance at a central portion, in the vehicle width direction, of the bumper reinforcement is the maximum and the distance decreases gradually continuously toward an outward direction of the vehicle.
