Claims

[Scope of utility model registration request]

In an automobile lamp having a lamp housing, a cylindrical part is integrally connected to the rear end of the lamp housing, at least three outer flange-like protrusions are formed on the cylindrical part, and the cylindrical part The outer circumferential surface of the waterproof cover is configured in a stepped manner so that the diameter becomes smaller on the rear side with the outer flange-like protrusion as a boundary, and the waterproof cover has a cylindrical portion that fits externally into the cylindrical portion of the lamp housing. Along with configuring
A plurality of inner flange-like protrusions are formed on the cylindrical portion of the waterproof cover, and the inner flange-like protrusions of the waterproof cover are fitted into the outer flange-like protrusions of the lamp housing, and the side surfaces of the outer flange-like protrusions and the inner flange-like protrusions are fitted into the outer flange-like protrusions of the lamp housing. A waterproof structure for an automobile lamp, characterized in that the side surfaces of the projections are brought into contact with each other, and the end surface of the cylindrical portion of the waterproof cover is elastically brought into close contact with the rear surface of the outer flange-like projection.
