ABSTRACT:
The present invention provides a method for manufacturing an automobile sunvisor, wherein a pair of overcoatings for the sunvisor, the rear surface of which is respectively covered with a layer of thermoplastic resin, is pressure-welded between an upper electrode member and a lower electrode member and cut at the same position without displacement, thus forming no protruding welded portion in the periphery of the sunvisor. Moreover, the pair of the overcoatings can be securely welded to each other without any particular portion for welding prepared in the overcoatings because the thermoplastic resin is melted inside the sealed portion of the pair of overcoatings during the pressure-welding.
