Abstract
A bumper beam formed of fiber reinforced resin containing continuous fibers oriented at least in the vehicle width direction sufficiently absorbs the collision energy of a high-speed collision in the fiber reinforced resin. The bumper beam also has a center portion positioned in the center in the vehicle width direction and protruding outward in the front-back direction, and right and left outer portions inclined from the respective ends of the center portion seen in the vehicle width direction toward the inner side in the front-back direction. The outer portions each have a resin foam member protruding outward in front-back direction. Thus, at the time of a low speed collision, the resin foam member is crushed to absorb part of the collision energy so that the energy is absorbed and distributed over the center and outer portions, protecting the car body frame from deformation.
