Therefore, in the process of tightening the box screw 15, a force in the direction shown by the arrow in FIG. 1 is applied to the abutting portion 14a, so that the plate frame body 1 can be prevented from being deformed such as warped. That is,
When the screw insertion hole 14 through which the box screw 15 is inserted is provided in the vicinity of the bending piece 4 and the gap 6, as compared with the case where the screw insertion hole is provided in both end pieces 5 of the plate frame body 1, the side piece 3 is provided. Since the strength is reduced, the plate frame body 1 is easily deformed, and the wiring device 11 may sink. Therefore, in the present embodiment, by providing the abutting portion 14a, the direction of the force applied by the box screw 15 can be directed to the outside of the plate frame main body 1, and the screw insertion hole 14 causes the bending piece 4 and the gap 6 to be formed.

a and the outer portion 3b are integrally formed in parallel with each other except the both end portions with a gap 6 interposed therebetween. Both ends of the plate frame body 1 at both ends at the inner end of the gap 6 between the both portions 3a, 3b. The flexible piece 4 having flexibility is formed integrally with the flexible piece 4. By the way, if the size of the plate frame main body 1 is the same as that of the first embodiment, it is clear that the width dimension of the both end pieces 5 becomes narrower by the amount that the opening 2 becomes larger than that of the first embodiment. is there. Therefore, if 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 bending amount of the bending piece 4 becomes smaller, so that the insertion force for inserting and locking the locking piece 13 of the wiring device 11 may be increased and the insertability may be deteriorated.

Therefore, in this embodiment, both ends of the gap 6 and the bending piece 4 are bent toward the opening 2 so that 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 set to be as large as possible, and the span of the gap 6 and the bending piece 4 can be lengthened. as a result,
The insertion force at the time of inserting and locking the locking piece 13 of the wiring device 11 can be reduced to improve the insertability, and the wiring device 11 can be easily attached to both ends of the opening 2 of the plate frame body 1. . Further, in the present embodiment, since both ends of the bending piece 4 are made substantially orthogonal to the both ends 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.

Further, as shown in FIG. 7, the bent portion 4a of the bending piece 4 is located on the front side of the plate frame main body 1 from the contact surface with the wall surface on the back side of the plate frame main body 1 where the embedding hole is provided. I have been drawn in. That is, by making the curved portion 4a lower than the contact surface with the wall surface, even if there is a projection around the embedded hole in the wall, the bending piece 4 can hit such a projection. Since the bending piece 4 absorbs the force applied to the wiring device 11, the damage to the plate frame body 1 can be reduced.

As shown in FIGS. 8 and 9, a decorative plate 23 is detachably attached to the front surface of the plate frame body 1. That is, a plurality of engaging pieces 24 are integrally provided on the back surface of the decorative plate 23, and engaging holes (decorative plate mounting portions) 25 that engage with the engaging pieces 24 are formed in the front surface of the plate frame body 1. I am doing it. 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 this embodiment, the decorative plate 23 for one wiring device corresponding to the opening 2 is used. Therefore, it is sufficient to use the decorative plate 23 provided with the opening windows 26 corresponding to the number of the wiring devices 11 used.
