Claims

[Scope of utility model registration request]

A lens mounting portion having a sealing groove is integrally formed on the periphery of the front opening of the lamp body, and a sealing leg protruding from the backside periphery of the front lens is inserted into the sealing groove and fixed with an adhesive. In a vehicle lamp in which a lance protruding from one surface of the leg is engaged with an engaging portion provided on one side wall portion of the seal groove or the rim, the lance is formed near the lance forming portion of the seal leg. A vehicle lamp characterized in that the distance between the tip of the surface opposite to the surface and the opposing side wall of the seal groove is wider than the distance of the portion where the lance is not provided.
