ABSTRACT:
A vehicle lighting device with a lamp compartment having a light source unit disposed therein. The light source unit includes a light emitting device as a light source and a projection lens as a light distribution control member for distributing light. A face bearing portion at a distal end of a lens mounting portion of the light emitting device corresponds to a rear surface of a collar portion disposed along an outer circumference of the projection lens. Complimentary extending projections and stepped portions on the collar portion and lens mounting portion are ultrasonically welded together, and burrs formed during the welding process are prevented from protruding toward the optical axis by an erect wall of the stepped portion.
