ABSTRACT:
An automobile bumper having an outer shape that forms a design surface. A mount is vibratorily welded to a back surface opposite to the design surface such that a fixture is fixed between the bumper body and the mount. The mount is melted by frictional vibration with the bumper body and so as to be integrally joined with that bumper body. Because the depth of the bumper body material being melted during vibrational welding does not reach the design surface, no shrinkages, uneven luster, welds or the like are produced on the design surface of the bumper body.
