Abstract
A vehicle lighting device manufacturing method, for joining a transparent cover with a housing ray welding, includes: a preliminary heating step of preparing welding portions of the transparent cover and the housing, and of forming, on part of the welding portion of the transparent cover and/or the housing, a built-up portion, which overlays a welding portion in a design, and heating and softening the built-up portion; a pressure-bonding step of pressure-bonding the welding portion of the transparent cover to the welding portion of the housing; and a welding step of welding the transparent cover and the housing that are pressure-bonded together by the emission of a light beam that irradiates the welding portion of the transparent cover and the housing along the entire length of edges.
