Abstract
A vehicle bumper beam, attached at its ends to side members of a vehicle through respective impact absorbing members. The bumper beam is press-formed into a predetermined shape. A width W2 of a connecting portion at an end portion thereof is larger than a width W1 of a connecting portion at a center portion thereof. A height H1 of a protruding portion at an end portion thereof is smaller than a height H2 of a protruding portion at a center portion thereof. A connecting portion between the protruding portions cooperates with the protruding portions to define an M-shaped configuration. The opposite end portions have a bending strength higher than a crush strength of the impact absorbing members.
