BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor wiring device.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, an embedding box 1 which is substantially box-shaped and has an opening 1a which is buried in the floor with an opening 1a facing the floor surface. A cover 2 attached to the opening 1a and provided with a rectangular opening 2b communicating with the opening 1a, and a projecting portion 3a protruding forward. The projecting portion 3a is provided with two outlets 3b. The bent wiring device main body 3 and the rectangular frame-shaped central piece 4 having the mounting hole 4a for mounting the wiring device main body 3 with the protruding base 3a exposed, and both ends of the central piece 4 are bent. A metal instrument holding plate 7 composed of side pieces 5 and 6 formed integrally with the central piece 4 by being formed, and provided at the edges of both side pieces 5 and 6, respectively, and the protruding base 3a is formed with an opening hole. 2b
And a mounting hole 8, 8 for mounting the device holding plate 7 to the cover 2 with the wiring device body 3 accommodated in the embedding box 1, and a window communicating with the opening 2b. There is provided a floor wiring device including a cover plate 9 that covers the hole so as to be openable and closable, and a plate block 10 that is attached to the cover 2 and fixed to a floor surface. In this floor wiring device, when the wiring device body 3 is used, the wiring device body 3 can be exposed by opening the cover plate 9,
When not in use, the cover plate 9 is closed and stored on the floor, so that the aesthetic appearance of the room can be improved.

[0003]

By the way, as a result of the miniaturization of the wiring tool block A composed of the wiring tool body 3 and the tool holding plate 7 described above, as shown in FIG. Can be attached to the cover 2 provided with a round hole 2a having a smaller opening area than the cover 2 shown in FIG. Here, the tool holding plate 7 bends the central piece 4 in the shape of a rectangular plate provided with a mounting hole (not shown) for mounting the wiring tool body 3 and both ends of the center piece 4 in one direction. Central piece 4
