Vehicular lamp and method for producing same

Abstract

A vehicular lamp with improved appearance quality (i.e., having no burrs or the like) around the joint interface between a front lens and a lamp body, and sufficient joint strength even in regions where the joint interface shape changes three dimensionally. A sealing leg, formed on the front lens, has a tip face which abuts and is joined by laser welding to a receiving face formed on the lamp body. To carry out the welding operation, a laser beam is irradiated from the front side of the front lens to the receiving face through the sealing leg. Therefore, even if the laser beam enters diagonally, it can be reflected internally by both side faces of the sealing leg so that the beam reliably reaches the tip face. As a result, the energy of the laser beam is not reduced, making it possible to efficiently heat the lamp body.
