持片の耐久性が高くなる。According to the configuration of the first aspect, when the decorative plate is attached to the front surface of the plate frame main body, the decorative plate is guided by the outer side surface of the peripheral wall and driven into the step portion, and the decorative plate is accurately positioned with respect to the plate frame main body. It can be positioned at As a result, a beautiful appearance can be exhibited in the mounted state. In addition, a step portion for receiving the peripheral portion of the decorative plate in a form in which the outer peripheral edge of the plate frame main body and the outer peripheral edge of the decorative plate are flush with each other in front of a portion where the rear end surface is in contact with the mounting surface on the front surface of the peripheral wall. So that
The peripheral wall is not bent by the load acting on the decorative plate, and the plate frame body can be prevented from being damaged by the load from the decorative plate. Moreover, since the step portion is formed so as to be continuous with the inclined surface on the front side of the peripheral wall, not only the position of the decorative plate with respect to the plate frame body as described above, but also the position of the decorative plate by the inclined surface. Shift can be prevented. Furthermore, the wiring device is configured to be held between the first holding piece and the second holding piece, and the first holding piece and the second holding piece are formed along the side piece of the opening window, so that the plate is formed. The frame body will be reinforced. Attachment portions for attaching a fixture for bringing the plate frame body into close contact with the attachment surface are formed on both upper and lower pieces surrounding the opening window, and the first holding piece and the second holding piece are formed at a portion between the two attachment portions. Even if a load is applied to the plate frame body by the fixture attached to the mounting part,
Since the deformation such that the distance between the first holding piece and the second holding piece is increased does not occur, and the wiring device held between the first holding piece and the second holding piece is prevented from falling off. is there.
In addition, between adjacent locking recesses in the second holding piece,
A jig that opens to the front side of the plate frame main body and presses the wiring tool toward the first holding piece to release the engagement between the locking recess of the second holding piece and the locking projection of the wiring tool can be inserted. Opening holes allow easy removal of wiring equipment by simply removing jigs such as screwdrivers from the front side of the plate frame body and inserting them into the holes and applying force. It is. In addition, since one side of the wiring device is held by the non-flexible second holding piece, falling off of the wiring device is reliably prevented, and the pressing force from the jig is applied to the non-flexible second holding piece side. Since it works, it is easy to stabilize the fulcrum position of the jig, and the work of removing the wiring device is particularly easy.
Since only a force acts on the holding piece in a plane along the opening window, no force in an unnecessary direction acts on the first holding piece, and the durability of the first holding piece increases.

A space is formed between the inner peripheral surface of the wiring device 23 and the inner peripheral surface of the wiring device 3 such that the locking projection 4 of the wiring device 3 can be inserted. Here, the relationship with the peripheral wall 12 is set so that the first holding piece 21 does not protrude rearward from the rear end of the peripheral wall 12. On the other hand, the second holding pieces 22 are projected from the back surface of the plate frame main body 1, and locking recesses 24 are respectively formed in portions of the first holding pieces 21 facing the locking recesses 23. ing.
Here, too, a space is formed between the rear surface of the peripheral edge of the opening window 11 and the inner peripheral surface of the locking recess 24 so that the locking projection 4 of the wiring device 3 can be inserted. As shown in FIG. 6, the second holding piece 22 has an inclined surface opposite to the surface on which the locking recess 24 is formed at the base located forward of the rear end surface of the peripheral wall 12.
It is formed such that the thickness becomes 22a toward the base side. A part of the second holding piece 22 protrudes rearward from the rear end face of the peripheral wall 12, and the protruding portion has a locking recess.
On the surface opposite to the surface on which the plate 24 is formed, a plane 22b substantially perpendicular to the front surface of the plate frame main body 1 is formed. Further, on one surface of the second holding piece 22 on the side of the opening window 11, a guide surface 22 c which is inclined so as to increase in thickness from the tip to the base is formed up to the locking recess 23. A release hole 25 is formed in the plate frame main body 1 at a position between the pair of locking recesses 23 corresponding to one wiring device 3. Further, as shown in FIG. 3, a substantially U-shape is formed on the back surface of the plate frame main body 1 between the first holding piece 21 and the peripheral wall 12 and between the second holding piece 22 and the peripheral wall 12. The reinforcing rib 26 is protruded. First holding piece 21 and second holding piece 22
Is formed along the side edge of the opening window 11,
The plate frame body 1 has a function of reinforcing the plate frame body 1. In addition, the formation of the reinforcing ribs 26 allows the plate frame body 1 to be deflected by an external force acting when the plate frame body 1 is attached to an embedding box or the like. It is possible to prevent that. Further, since the first holding piece 21 and the second holding piece 22 are formed in a range between the upper and lower mounting portions 20, when the plate frame main body 1 is mounted on the mounting surface, the mounting portion 20 is not mounted. Even if a load is applied such that the rear surface is pushed rearward from the mounting surface, this deflection can be absorbed by the side portion of the mounting portion 20 in the plate frame main body 1.
And the second holding piece 22 can be prevented from being deformed.
That is, the left and right width of the opening window 11 can be prevented from changing,
This prevents the wiring device 3 from falling off. According to the above configuration, the wiring device 3 is connected to the plate frame main body 1.
When the wiring device 3 is mounted on the wiring device 3, the locking projection 4 provided on one side surface of the wiring device 3 is engaged with the locking recess 23 of the first holding piece 21, and the projection is formed on the other side surface of the wiring device 3. What is necessary is just to introduce the locking projection 4 provided into the locking recess 24 formed in the second holding piece 22 while abutting the locking projection 4 on the guide surface 22c. At this time, the wiring device 3 is pressed by the guide surface 22c and the first holding piece 2
1 is bent, and is finally introduced into the locking recess 24. On the other hand, in order to remove the wiring device 3 from the plate frame main body 1, a jig such as a driver is inserted into the removal hole 25 and the wiring device 3 is removed.
When a force is applied so as to press the first holding piece 21 toward the first holding piece 21, the first holding piece 21 bends and the second holding side 22
The wiring device 3 is released from the engagement with the wiring device 3, and the wiring device 3 can be removed from the plate frame main body 1. As described above, since only the front end of the second holding piece 22 projects rearward from the rear end face of the peripheral wall 12 of the plate frame main body 1, the first holding piece 21 and the second holding piece 22 are formed. Compared to the case where both protrude, the left and right width of the embedding hole can be reduced, and the construction becomes easier. Also, by increasing the thickness of the base of the second holding piece 22 to prevent the second holding piece 22 from breaking, the second holding piece 22 protrudes rearward from the rear end face of the peripheral wall 12. By making one surface of the portion having the flat surface 22b, the lateral width required for the embedding hole can be reduced as compared with the case where the second holding piece 22 projects with the same thickness as the base. In addition, it is possible to increase the amount of protrusion of the peripheral wall 12 so that the second holding piece 22 does not protrude from the rear end surface of the peripheral wall 12, but in that case, the amount of protrusion from the mounting surface increases, and the appearance is improved. You will lose. It is also conceivable to reduce the amount of protrusion of the second holding piece 22 from the back surface of the plate frame main body 1. However, the locking projection 4 on one side of the wiring device 3 is changed to the locking recess of the first holding piece 21. With inserted in 23,
Since a minimum dimension is required so that the locking projection 4 on the other side of the wiring device 3 abuts on the guide surface 22c of the second holding piece 22, the projecting amount of the second holding piece 22 is small. You can't. In the configuration of the present embodiment, all of these problems have been solved, and the opening width of the embedding hole is reduced while the required minimum amount of protrusion of the second holding piece 22 is ensured to facilitate construction. You can do it.

いう利点もある。As described above, in the configuration of claim 1, when the decorative plate is attached to the front surface of the plate frame main body, the decorative plate is guided by the outer side surface of the peripheral wall and driven into the step portion, and the decorative plate is attached to the plate frame main body. It is possible to accurately determine the position. As a result, there is an advantage that a beautiful appearance can be exhibited in the mounted state. Also,
A step receiving the outer peripheral edge of the plate frame body and the peripheral portion of the decorative plate is formed in front of the portion where the rear end surface is in contact with the mounting surface on the front surface of the peripheral wall. Can be prevented from being bent, and damage to the plate frame body due to the load from the decorative plate can be prevented. Moreover, since the step portion is formed so as to be continuous with the inclined surface on the front side of the peripheral wall, not only the position of the decorative plate with respect to the plate frame body as described above, but also the position of the decorative plate by the inclined surface. This has the advantage that displacement can be prevented. Further, the wiring device is configured to be held between the first holding piece and the second holding piece,
Since the first holding piece and the second holding piece are formed along the side piece of the opening window, the plate frame body is reinforced. Attachment portions for attaching a fixture for bringing the plate frame body into close contact with the attachment surface are formed on both upper and lower pieces surrounding the opening window, and the first holding piece and the second holding piece are formed at a portion between the two attachment portions. Therefore, even if a load is applied to the plate frame main body by the fixture attached to the mounting portion, the deformation such that the distance between the first holding piece and the second holding piece is increased does not occur. There is an advantage that the drop of the wiring device held between the first holding piece and the second holding piece is prevented. In addition, between the locking recesses adjacent to each other in the second holding piece, an opening is opened on the front side of the plate frame main body, and the wiring device is pressed toward the first holding piece side, and the locking recess of the second holding piece and the wiring device are connected. The jig for releasing the engagement state with the locking projection is opened with an insertion hole where a jig such as a screwdriver can be inserted from the front side of the plate frame body. Thus, there is an advantage that the wiring device can be easily removed, and the work of attaching and detaching the wiring device is easy. Moreover,
Since one side of the wiring device is held by the non-flexible second holding piece, the wiring device is reliably prevented from falling off, and the pressing force from the jig acts on the non-flexible second holding piece side. Since the fulcrum position of the jig is easily stabilized, the work of removing the wiring device is particularly easy, and only the force acts on the first holding piece in the plane along the opening window. There is also an advantage that the force of the unnecessary direction does not act on the first holding piece and the durability of the first holding piece is increased.
