Then, when the fitting claw pieces of the decorative plate 2 are fitted into the fitting holes 15 and the decorative plate 2 is attached to the plate frame 1, the attachment of the wiring fixture 6 to the wall surface 10 is completed.
Incidentally, the mounting frame 5 is formed with a hole 52 into which the scissors are inserted when the scissors are used. As described above, in this embodiment, the plate frame 1 is fixed from the front side to the mounting frame 5 attached to the embedded box 7 with the plate screws 4. After installation, you can finish the walls of apartments, etc. (cloth pasting). Therefore, in this embodiment, it is only necessary to attach the plate after finishing the wall material, thereby reducing the amount of work required before completion of the wall material and shortening the construction period. In addition, since the mounting structure is such that the plate frame 1 is fixed from the front side to the mounting frame 5 attached to the embedded box 7 with the plate screws 4, the mounting frame 5 is temporarily fixed to the plate frame 1' as in the conventional case. Therefore, the problem of the mounting frame 5 floating when the mounting frame 5 is fixed to the embedded box 7 does not occur.

Embodiment 2 FIG. 2 shows another embodiment of the present invention. In this embodiment, the plate is fireproof. For this reason, a fireproof panel 3 shown in FIG. 2 is provided. In addition, in the following explanation, only the characteristic parts when used for fireproofing will be explained. The fireproof panel 3 has a flat plate shape, and has an opening 31 formed in the center through which the wiring device 6 is inserted. Temporary fixing pieces 34 are provided to protrude backward from the four corners of both side edges, respectively, and these temporary fixing pieces 3
4 is inserted into the insertion hole 16 of the plate frame 1, so that the fireproof panel 3 can be temporarily fixed from the front side of the plate frame 1. Insertion holes 32 for passing the plate screws 4 are formed at both ends of the fireproof panel 3 at positions corresponding to the screw holes 14 of the plate frame 1. Further, in a portion of the fireproof panel 3 corresponding to the fitting claw piece of the decorative plate 2, an insertion hole 35 through which the fitting claw piece is inserted is bored.

In a fireproof plate like this embodiment, when fixing the plate frame 1 to the mounting frame 5, first insert the temporary fixing piece 3 of the fireproof panel 3 into the insertion hole 16 of the plate frame 1.
