DESCRIPTION OF THE PREFERRED EMBODIMENTS In a lighting fixture A, a socket 8 for holding a lamp (not shown) is attached to a main body 1, a reflection plate surface 9 is formed on the main body 1, and the reflection plate 4 can be detached from the main body 1. To form a Fuji-type lighting fixture.
Hereinafter, a configuration for attaching the reflection plate 4 to the main body 1 will be described in detail.

A substantially V-shaped mounting spring piece 3 is resiliently inserted into a holding hole 2 formed in the main body 1 and is resiliently inserted into a mounting hole 5 formed in a reflection plate 4. Free end piece 3
a is pressed and deformed so that the mounting spring piece 3 escapes from the mounting hole 5 and the reflector 1 is detachably mounted on the main body 1. The mounting spring pieces 3 are formed at both ends of a mounting spring 10 having a bent spring plate. The mounting springs 10 utilize the spring properties of the main body 1 and the mounting spring pieces 3 at both ends are elastically inserted into the holding holes 2 and held. Installed in condition. An operation hole 11 for elastically deforming the free end piece 3a to cause the mounting spring piece 3 to escape from the mounting hole 5 and remove the reflection plate 4 is provided in the main body 1 at a position corresponding to the free end piece 3a on the back of the main body 1. Is formed.

As shown in FIG. 2A, when the reflector 4 is mounted, a substantially V-shaped mounting protruding inward from the back of the main body 1 with the mounting operation of the reflector 4 is performed. The spring piece 3 is elastically deformed, and the mounting spring piece 3 is elastically inserted into the mounting hole 3 of the reflection plate 4 for mounting. At the time of removal, as shown in FIG. 2B, an operating tool such as a flathead screwdriver inserted through the operation hole 11 is inserted to elastically deform the free end piece 3a and the mounting spring piece 3 of the mounting spring piece 3. Then, the mounting spring piece 3 is removed from the mounting hole 3 of the reflecting plate 4, and the reflecting plate 4 is removed. Thus, the free end piece 3a can be elastically deformed to attach and detach the reflection plate 4, thereby reducing the operation force. Then, the free end piece 3a is elastically deformed by the operation tool to perform the detachment, so that the detaching force can be further reduced. The mounting spring 10 is hidden behind the back of the main body 1, and the operation hole 11 for inserting the operation tool can be made small.

FIG. 3 shows another embodiment, in which locking pieces 12 are formed by folding back substantially U-shaped on both upper end portions of a substantially U-shaped reflecting plate 4. The locking piece 12 is locked to the end of the mounting spring piece 3 while the reflector 4 is being mounted, so that the reflector 4 is prevented from dropping unexpectedly. By locking to the spring piece 3, the reflection plate 4 can be temporarily fixed to the main body 1, and in order to prevent the reflection plate 4 from dropping, for example, the reflection plate 4 is connected to the main body 1 with a string or the like. This prevents the attachment of the reflection plate 4 from being hindered by such a string, and even if the free end piece 3a is strongly pressed to permanently deform the attachment spring piece 3, 4 can be temporarily held by the locking pieces 12 to prevent the reflection plate 4 from dropping, and if the substantially inverted U-shaped locking pieces 12 are attached. In the state that the locking at one 3, as shown in FIG. 3 (b), the gap d between the reflecting plate 4 and the body 1 Noto
The reflection plate 4 is elastically deformed by an amount corresponding to the gap d, and the locking piece 12 is locked to the mounting spring piece 3 so as to reliably prevent the dropping. In addition, the gap d is found on the appearance. This makes it possible to find the incomplete attachment of the reflector 4 and correct it so that the reflector 4 can be attached as specified.

[0011]

As described above, according to the present invention, the free end and the mounting spring of the substantially V-shaped mounting spring mounted on the main body are elastically deformed, and the mounting spring is inserted into the mounting hole of the reflector. When the reflector is attached to the main body, the free end piece is elastically deformed, the mounting spring piece is released from the mounting hole, and the operation hole for inserting the operation tool for removing the reflector is provided at the back end of the main body. Since the free end piece is elastically deformed, the free end piece can be elastically deformed to mount and remove the reflector, reducing the operating force. The removal force allows the removal force to be further reduced,
Further, since the mounting spring is hidden behind the back of the main body and the operation hole for inserting the operation tool can be made small, there is an advantage that these are not conspicuous and the appearance can be improved.
