Claims

[Scope of utility model registration request]

A flange with an annular groove formed on the outer peripheral surface is protrudingly provided around the bulb mounting hole of the lamp housing, which has a lens fitted on the front and a bulb mounting hole opened on the rear. The bulb is fluid-tightly mounted to the lamp housing by press-fitting the cylindrical mounting portion of the elastic cover on which the bulb is mounted in a fluid-tight manner, and fitting the protrusion on the inner periphery of the mounting portion into the annular groove. In the automotive lamp, a taper guide is provided on the outer circumferential surface of the tip side of the flange to expand the mounting portion of the cover in the radial direction, and a plurality of housing guide portions are provided in the annular groove at equal intervals in the circumferential direction, The cover is composed of a mounting part made of a soft material and a main part fitted into the mounting part, and a fitting protrusion fitted between the housing guide parts in the annular groove is provided on the inner periphery of the mounting part. The automotive lamp also has a sealing lip protruding from the inner surface of the main part that is pressed into contact with the end face of the flange.
