A bumper beam structure includes a bumper beam that extends in the vehicle-width direction and that has a closed section formed by an outer vertical wall, an inner vertical wall, a top member, and a bottom member and a reinforcing member that is mounted inside the closed section of the bumper beam at the center in the vehicle-width direction of the bumper beam. The reinforcing member has a pair of angled members that diverge in the vehicle-width direction from the outer vertical wall toward the inner vertical wall and, in a minor collision, causes an impact load to act as a tensile force on the inner vertical wall of the bumper beam through the angled members. The angled members are spot-welded to the bottom member with mounting surfaces therebetween. In a major collision, spot welding points fracture after the bumper beam collapses, thereby absorbing impact energy.
