[Background Art] Fig. 7 shows a mounting frame 1 made of an insulating material for detachably attaching a conventional wiring device such as a switch, and Fig. 8 is a view showing a construction state. The mounting frame 1 is made of a synthetic resin, and has an opening 2 in the center where a wiring device 8 is arranged. Elongated holes 5 through which screws for screwing into the screw holes 4a of the mounting pieces 4 of the embedding box 3 are inserted are formed above and below the mounting frame 1. Also, screw holes 9 are provided above and below the long hole 5 into which screws 7 for attaching the decorative plate 6 are screwed.
An opening 6 a for exposing the wiring device 8 is opened at the center of the decorative plate 6. The illustrated mounting frame 1 has such a size that three wiring devices 8 each having a size of one module (unit size) can be arranged vertically. On one side piece 10 of the mounting frame 1, three pairs of locking holes 12 penetrating left and right are formed. The other side piece 11 of the mounting frame 1 is provided with a locking side piece 13 which is parallel to the side piece 11 and has flexibility below the side piece 11.
Are integrally formed. With both ends of this locking side piece 13,
At the middle two places, the side pieces of the mounting frame 1 are
11 and the locking side piece 13 are integrally connected.

A flexible locking claw 15 having a convex shape is integrally and projecting upward from the locking side piece 13 between the bridging pieces 14, and a release piece 15 a at a central portion is an outer surface of the side piece 11. The step 15b on both sides of the release piece 15a is located below the lower surface of the side piece 11, and the step 15b and the side piece 11 form a locking hole 16 facing the locking hole 12 doing.

By the way, as shown in FIG. 8, a wiring device 8 constituting a switch attached to the mounting frame 1 has an outer shell composed of a body 8a and a cover 8b. The body 8a and the cover 8b are assembled by two metal assemblies. The two are assembled by frame 17 and joined together.
A pair of locking pieces 18 are integrally formed on the outer side of the assembly frame 17 so as to protrude laterally.
The wiring device 8 is detachably attached to the attachment frame 1 by being inserted and locked to the 12, 16. Here, the attachment and detachment of the wiring device 8 can be facilitated by bending the locking claw 15 of the locking side piece 13 when attaching and detaching the wiring device 8.
