A work is generally performed by attaching a wiring device to the box cover 50 and further attaching a decorative cover. When the box cover 50 is attached to the box, screw holes 51 provided on the box cover 50 are aligned with attachment holes provided on the periphery of the opening of the box, and the box cover 50 is attached with screws.

[0003] In such a construction, the box is often installed in an inclined state due to an impact at the time of concrete casting. For this reason, the screw hole 51 is formed by a long hole so that the box cover 50 can be attached in a straight state corresponding to the inclination of the box.

However, in the case of a box cover having such a long screw hole, as shown in FIG. Therefore, there is a problem that the toro (mortar) enters the box 60. Also, depending on the situation at the site, a box cover having a long screw hole may be buried in a concrete wall with the box cover previously attached to the box. There was a problem that toro (concrete) invaded.

[0005] For this reason, in the conventional box cover, the screw hole which is a long hole cannot be so large, and the range which can cope with the inclination of the box is limited.

[0006]

[0011]

In the mounting method according to the first aspect of the present invention, unlike the case where a conventional box cover in which screw holes are formed in advance is used, a screw hole formed of a transparent body and mounted on the box is provided. The box cover having the piercable plate portion allows a screw hole corresponding to the mounting hole of the box to be formed later. This screw hole is formed at a mounting position where the box cover is in a predetermined state through a box cover formed of a transparent body, and the size thereof can be formed with a size enough to insert a screw, so that it can be formed when embedding or At the time of finishing the wall surface, it is possible to completely prevent the toro from entering the box through the screw hole.

In the box cover according to the second aspect of the present invention, since the box cover is made of a transparent material, the position of the mounting hole of the box can be easily confirmed from the front of the box cover when the box cover is applied to the box. By providing a screw hole corresponding to the mounting hole of the box on the plate portion, the box cover positioned in a predetermined state with respect to the box can be mounted. The screw hole provided when mounting to the box can be formed with a size enough to insert the screw, so that the toro enters the box from the screw hole at the time of embedding or finishing the wall surface. It can be completely prevented.

Also, unlike a box cover having a long slotted screw hole, which can only cope with an inclined box to a limited extent in order to reduce the intrusion of the toro into the box from the screw hole. In the case of the present box cover, even a relatively inclined box can be mounted by providing a screw hole corresponding to the mounting hole of the box in the plate portion.

Since the box cover is made of a transparent material, it is not only a box having a size corresponding to the box cover but also a box having a smaller size or a special size (a size not conforming to the JIS standard). With respect to the box of (1), the position of the mounting hole of the box can be easily confirmed through the box cover made of the transparent body, and a screw hole can be provided to efficiently mount the box.

Further, in this box cover, since the plate portion is provided with a display indicating the position corresponding to the mounting hole of the box of a predetermined size, the position of the box cover relative to the mounting hole can be easily determined. The drilling operation can be quickly performed by aligning the tip of the drill with the display.
The box cover provided with such an indication is particularly effective for a box to which the box cover is attached is specified by JIS standards.
