Abstract:
A fusion-welding leg in a vehicle lamp for attaching a vehicle lamp lens to a vehicle lamp body by vibration-fusion-welding a joint surface of the fusion-welding leg to a joint surface of the lamp body, the fusion welding leg comprising:a front end,an inside surface facing an inside of the vehicle lamp and extending from the front end of the fusion-welding leg, andan outside surface facing an outside of the vehicle lamp and extending from the front end of the fusion-welding leg, andwherein the inside surface is perpendicular to the joint surface of the lamp body, and the outside surface is tapered so as to increase a width of said fusion-welding leg in a direction away from the front end; andwherein said fusion welding leg is made of a resin material having a thermal melting temperature which is higher than a thermal melting temperature of the lamp body at the joint surface of the lamp body.
