The wiring box 11 is used on the back side of the partition wall through a mounting bracket fixed to the partition column, or is used by being embedded in concrete. The bolt hole 14 provided in the center of the bottom wall 12 is used for attaching a bolt to a formwork when concrete is placed, but is not necessary when the wiring box 11 is disposed on the partition wall. The bottom wall 12 and the peripheral wall 13 are provided with knockouts 15 that are punched to insert the cable 61 as necessary. Further, a pair of mounting flanges 17 for mounting the box cover 21 on the front surface of the opening 16 are provided on the peripheral edge 16 a of the opening 16 of the wiring box 11, and a screw hole 18 is provided in the center of each mounting flange 17. . The wiring box 11 is formed by pressing a metal plate such as a steel plate or integrally molding a synthetic resin.

  Further, the box cover 21 constituting the wiring fixture mounting body is formed in a square frame shape, and the central portion bulges in a trapezoidal shape on one side at a constant height, and almost the entire bulged trapezoidal portion is opened. The opening 22 is formed. A part of the opening 16 of the wiring box 11 is exposed from the opening 22. The opening 22 is formed in a substantially oval shape, and the periphery thereof is formed in a straight line in which the upper and lower portions are curved outward in an arc shape and the left and right side portions are parallel. Arc-shaped long holes 23 are formed in the circumferential direction at positions corresponding to the screw holes 18 of the wiring box 11 at the four corners of the flat portion around the outside of the opening 22 of the box cover 21, and one end of the long hole 23.

The box cover 21 is formed by pressing a metal plate such as a steel plate or integrally molding a synthetic resin.

  Next, as shown in FIG. 5, the anti-sliding body 31, which is a feature of the present invention, is formed of a synthetic resin in a substantially T-shape when viewed from the front, and the vertical portion is cylindrical and attached inside. A screw insertion space 34 through which the shaft portion 51a of the screw 51 is inserted is formed. The sliding contact prevention body 31 is arranged in the screwing direction of the mounting portion 32 to be attached to the box cover 21 and the mounting screw 51 to be screwed into the screwing portion of the box cover 21. And a sliding contact preventing portion 33 for preventing the cable 61 from entering the planned space 20. Here, with respect to the sliding contact prevention body 31, the front means a surface that can be seen from the inside of the opening 22 of the box cover 21. Further, the screwing direction of the mounting screw 51 is, as shown in FIG. 7, the arrow direction indicated by the one-dot chain line of the mounting screw 51, and the screwing direction described later is the opposite direction.

  First, the attachment portion 32 of the sliding contact prevention body 31 is a portion attached to an attachment flange 24 that is an instrument attachment portion of the box cover 21, and is formed in a T-shaped horizontal portion. It is formed by two upper and lower abutting portions of a front side abutting portion 35 and a back side abutting portion 36 extending in the direction. The front contact portion 35 is located on the outer surface side of the attachment flange 24 of the box cover 21 when the sliding contact prevention body 31 is attached to the box cover 21, and the back contact portion 36 is on the inner surface side of the attachment flange 24. The front-side contact portion 35 and the back-side contact portion 36 are provided as a pair on the left and right sides with a gap 37 at the center. A central gap 37 between the pair of left and right contact portions is a space through which the shaft portion 51a of the mounting screw 51 passes vertically. A groove portion 38 formed between the upper and lower surfaces of the front-side contact portion 35 and the back-side contact portion 36 is a space into which the attachment flange 24 of the instrument mounting portion of the box cover 21 is press-fitted, and the front-side contact portion The attachment flange 24 is sandwiched between 35 and the back side contact portion 36. In addition, in order to further increase the clamping force with respect to the attachment flange 24, both contact parts may be integrally provided with a small projection such as a hemisphere that is elastically pressed against the contact surface.

  Further, the front contact portion 35 of the attachment portion 32 is a surface of the attachment flange 51 of the box cover 21 on the screwing direction side, that is, the upper side of the attachment flange 24 in FIGS. 3 (a) and 3 (b).

  In addition, the sliding contact preventing body 31 may be entirely made of a synthetic resin and may be flexible or soft. Moreover, you may form with another material.

  In the above-described mounting of the wiring device to the wiring device mounting body, the sliding contact preventing body 31 is attached to the attachment flange 24 of the box cover 21 after the wall hole 72 is provided in the partition wall 71. Alternatively, the wall hole 72 may be provided after the sliding contact prevention body 31 is installed on the back of the wall with the box cover 21 attached. In this case, forgetting to attach the sliding contact preventing body 31 to the box cover 21 can be prevented. Since the sliding contact prevention body 31 is separate from the box cover 21, if the sliding contact prevention body 31 interferes with work when the cable 61 is pulled in or connected, the sliding contact prevention body 31 is temporarily removed. The cable 61 can be attached again after being pulled in and connected.

  Moreover, in the said embodiment, although the sliding contact prevention body 31 is attached to both of a pair of instrument attachment parts, such as the box cover 21, the cable 61 is due to be routed around one of the instrument attachment parts. In such a case, the anti-sliding body 31 may be attached to only one of the pair of instrument mounting portions, or in the case where there are a plurality of pairs of instrument mounting portions, or one of them, It is not always necessary to attach to all instrument mounting parts.

  Furthermore, in the said embodiment, the sliding contact prevention body 31 and the sliding contact prevention part 33 show what is attached or provided in the wiring box 11 and the box cover 21 which are arrange | positioned on the back side of the partition wall 71 or a concrete wall. However, the present invention can be similarly applied to a case where an outlet fitting, a switch fitting, or the like is attached to a duct in which a wiring member is drawn.
