[Detailed description of the invention]

[0001]

The present invention is applied to a stop lamp or the like usually called a high mount stop lamp which is installed on a rear panel provided behind a rear seat of an automobile so as to face an inner surface of a rear window glass. And vice versa.

[0002]

2. Description of the Related Art In recent automobiles, a high-mount stop lamp is provided separately from an existing stop lamp.
Built into the rear spoiler and vehicle compartment provided on the rear upper surface of the
By illuminating this together with the stop lamp at the time of brake operation, the driver of the following vehicle is further alerted to ensure safety.

As such a high mounted stop lamp, one using a general incandescent bulb or light emitting diodes have been proposed (e.g. Japanese Patent Open Rights 1-146376
No., Japanese Utility Model Publication No. 2-4404, etc.). Further, as a conventional example in which such a high-mount stop lamp is disposed in a vehicle cabin, for example, those disclosed in Japanese Utility Model Laid-Open No. 60-96156 and Japanese Utility Model Laid-Open No. 63-192149 are known. In each case, the housing is fixed on the rear panel by a suitable means such as a set screw. The structure of mounting the bulb in such a stop lamp is roughly classified into two types: a structure in which the bulb is mounted in a bulb mounting hole provided in the rear surface of the housing, and a structure in which the stop lamp is disposed on the bottom surface of the housing. The former has the advantage that the bulb can be easily replaced because the bulb is inserted from the rear side of the housing, but has the disadvantage that the gap between the rear side and the bulb is narrow, the reflector is difficult to install, and the amount of irradiated light is reduced. On the other hand, although the reflector can be installed and the irradiation light amount can be increased, there is a disadvantage that the bulb replacement is troublesome.

Reference numeral 4 denotes a body, 5 denotes a valve disposed in a valve mounting hole 6 of the body 4 via a valve socket (not shown), 7 denotes a reflector, and 8 denotes a lens mounted on a front opening of the cover 1. The body 4 is installed and fixed on the rear panel in advance, and is covered by the housing 3 after the valve 5 and the reflector 7 are attached.

[0005]

However, in such a conventional high-mount stop lamp, since each functional part as a lamp is constituted by an independent part, the number of parts is large, and the manufacturing cost and cost are reduced. There is a disadvantage that the number of assembling steps increases and the cost increases. Further, in a structure in which the body 4 is fixed to the rear panel with a set screw or the like, the work of attaching the body 4 and the work of attaching and detaching the housing 3 when replacing the valve are troublesome.

Accordingly, the present invention has been made in view of the above-mentioned conventional problems. It is an object of the present invention to simplify the structure and reduce the number of assembling steps and manufacturing costs. The present invention provides a vehicular lamp capable of performing one-touch operation.
