<p>Intended is to provide a door impact beam capable of increasing a buckling strength against an input load. The door impact beam (1) comprises a beam member (10) having two beads (11 and 12) formed in its longitudinal direction, an opening preventing reinforcement (20) for suppressing the deformation of the opening of the beads in the opening direction, and a closing preventing spacer (30) for suppressing the deformation of the bead (11) and the bead (12) in the closing direction.</p> |
