Abstract:
This lamp fixture for a vehicle comprises a lamp housing with an interior space and a cover that covers the interior space, the cover and the lamp housing being joined by welding, wherein: the cover is provided with a design surface section, an outer surface of which faces outward from the vehicle, and a welding leg section that protrudes from the design surface section; the lamp housing is provided with a joining section for welding that is joined to the welding leg section; and the welding leg section, melted by heating of a heating plate, and the joining section for welding, melted by irradiation with laser light, are joined. Due to the foregoing, melting is performed separately in a state in which the joining section for welding is not melted by the heating plate and the joining section for welding and the welding leg section do not abut one another, so a stable joining state of the lamp housing and the cover can be maintained without a steep rise in manufacturing costs.
