A separate body chassis 1 can be made unnecessary. That is, since the integrally structured reflector plate 21 itself also serves as the main body chassis, costs can be reduced, and
The entire device can be made lighter and thinner, and can be made into the smallest shape. Therefore, it also looks better. Furthermore, assembly and installation on the mounting surface 61 are extremely simple. Furthermore, disassembly and removal are also easier.

Furthermore, even when assembling the lamp socket 46, the socket 46 can be directly attached to the reflector plate 21.
The main body chassis 1 and the lamp socket mounting bracket 2 as in the conventional case are not required, and the cost can be reduced. Moreover, as described above, the socket 46 can be easily attached without using screws or the like. Nevertheless, the socket 46 does not easily come off due to the action of the socket base 47 having the hook-shaped claw portion 52 and the protrusion 53 as the locked portion.

Further, since the mounting hole 27 for mounting the lamp socket 46 in the reflector plate 21 is completely closed by the socket pedestal 47 in addition to the socket 46, the appearance is not spoiled. Rather, by using a socket stand 47 with a large degree of freedom in shape for fixing the socket 46,
It becomes possible to differentiate in terms of design.

That is, in addition to the socket base 47 shown in the above-mentioned embodiments, there are various types of socket bases 47, such as a box-shaped socket integrally formed with a cover portion 71 that almost covers the periphery of the lamp socket 46, as shown in FIG. Any shape is possible.

Further, in the above embodiment, the entire mounting hole 27 and the locking piece 30 are located on the same plane, but the locking piece 30 is cut into a roughly L-shaped cross section as shown in FIG. It may also be formed by raising it.

〔Effect of the invention〕

According to the present invention, the reflector has a socket insertion portion into which the base of the lamp socket can be inserted, and a locking piece portion on both sides that is continuous with the socket insertion portion and engages with grooves on both sides of the base of the lamp socket. A mounting hole consisting of a socket fitting part is provided, and a socket base is fitted into the lamp socket fitted to the socket fitting part through the socket insertion part of the mounting hole, so that the socket base is provided with a socket base. The socket insertion part of the mounting hole is closed by the closing part, and the locked part provided on the socket base is engaged with the periphery of the socket insertion part of the mounting hole, making it possible to mount the socket on the main body chassis like in the past. Even without metal fittings, the lamp socket can be easily and reliably attached to the reflector plate without coming off, and costs can also be reduced. Furthermore, when the lamp socket is attached, the mounting hole is not visible, so the appearance is good, and the socket stand also allows for differentiation in terms of design.

In addition, the reflective plate is provided with a protrusion that bulges on the reflective surface side,
If the lighting unit for the lamp is integrally installed within this convex part, combined with the above-mentioned fixed structure of the lamp socket, it is possible to eliminate the need for a main body chassis that is separate from the conventional reflector, reducing costs. This allows the entire device to be made thinner, and the device itself can be easily assembled, disassembled, attached, and removed.
