Abstract

PURPOSE:To increase the rigidity of the entire bumper by thermally fusing two half bodies and constructing a bumper beam associated with a flange section, then thermally welding said flange section and the inner wall face of a bumper face. CONSTITUTION:A bumper beam 2 composed of thermoplastic resin reinforced with long glass fibers is formed by thermally welding the edge section and the central section of two half bodies 5, 6. The flush flange section 2a of said bumper beam 2 is thermally welded to the inner wall face 1a of a bumper face 1 and jointed. Since the half bodies 5, 6 constituting the bumper beam 2 are jointed at the central section and both edge sections, sufficient rigidity can be exhibited. Furthermore, since the bumper beam 2 and the bumper face 1 are jointed at the flange section 2a and the inner wall face 1a, sufficient jointing area can be ensured resulting in improvement of the rigidity of the bumper as a whole.
