The above-mentioned flexible piece 4 having flexibility is integrally formed with the above. By the way, assuming that the dimensions of the plate frame main body 1 are the same as those of the first embodiment, it is obvious that the width dimension of the both end pieces 5 is reduced by the extent that the dimension of the opening 2 is larger than that of the first embodiment. is there. Therefore, when the gap 6 reaches the inside of the end piece 5 having a reduced width, the strength of the end piece 5 may be reduced. On the other hand, when the span of the gap 6 becomes shorter, the amount of bending of the bending piece 4 becomes smaller, so that the insertion force when inserting and locking the locking piece 13 of the wiring device 11 may increase, and the insertability may decrease.

Therefore, in the present embodiment, by bending both ends of the gap 6 and the bending piece 4 toward the opening 2, the gap 6 is formed from the outer peripheral side surface of the plate frame body 1 corresponding to the end piece 5. The distance d to the tip (see FIG. 5A) is made as long as possible, and the span of the gap 6 and the flexure piece 4 can be made longer. as a result,
The insertion force at the time of inserting and locking the locking piece 13 of the wiring device 11 is reduced to improve the insertability, and the mounting of the wiring device 11 at both ends of the opening 2 of the plate frame main body 1 can be facilitated. . Further, in the present embodiment, since both ends of the bending piece 4 are substantially perpendicular to the both end pieces 5 of the plate frame body 1, there is an advantage that stress concentration on both ends of the bending piece 4 can be minimized. is there.

I'm drawn in. In other words, by making the bent portion 4a one step lower than the contact surface with the wall surface, even if there is a protrusion around the embedding hole in the wall surface, the bending piece 4 can hit such a protrusion. In addition, the force applied to the wiring device 11 is absorbed by the flexure pieces 4 so that damage to the plate frame main body 1 can be reduced.

As shown in FIGS. 8 and 9, a decorative plate 23 is detachably mounted on the front surface of the plate frame main body 1. As shown in FIG. That is, a plurality of engaging pieces 24 are integrally formed on the rear surface of the decorative plate 23 to project therefrom, and an engaging hole (decorative plate mounting portion) 25 for engaging with the engaging pieces 24 is formed in the front surface of the plate frame body 1. I have. An opening window 26 for exposing the front surface of the wiring device 11 is provided at the center of the decorative plate 23. In the present embodiment, a decorative plate 23 for one wiring device corresponding to the opening 2 is used. Therefore, according to the number of wiring devices 11 used, it is only necessary to use the decorative plate 23 provided with the opening windows 26 corresponding to the used number.

The wiring device 11 to the plate frame body 1
The attachment / detachment operation is the same as that of the first embodiment, and therefore the description is omitted.
