## Abstract

A wiring box includes: a top plate having an opening; a lid body which opens and closes the opening of the top plate; and a rotating arm, one end of the rotating arm being rotatably supported inside the opening of the top plate and another end of the rotating arm rotatably supporting the lid body, wherein the lid body is elevated while being held in a substantially vertical state inside the opening of the top plate by rotation of the rotating arm, and the opening of the top plate is closed by rotation of the lid body at a surface of the opening of the top plate so that a surface of the top plate and a surface of the lid body form a uniform surface.

## Claims

### Claim 1

A wiring box comprising:
a top plate having an opening;
a lid body which opens and closes the opening of the top plate; and
a rotating arm, one end of the rotating arm being rotatably supported inside the opening of the top plate and another end of the rotating arm rotatably supporting the lid body, wherein
the lid body is elevated while being held in a substantially vertical state inside the opening of the top plate by rotation of the rotating arm, and
the opening of the top plate is closed by rotation of the lid body at a surface of the opening of the top plate so that a surface of the top plate and a surface of the lid body form a uniform surface.

### Claim 2 (depends on 1)

The wiring box according to claim 1, further comprising:
a slide pin which is provided in the lid body; and
a slide groove which is linked to the slide pin and provided in the wiring box, and
wherein the slide groove is configured to include a slide groove to hold the lid body in the substantially vertical state as the lid body is elevated, and a slide groove to guide the lid body to be rotated at the surface of the opening, which are continuously formed.

### Claim 3

A method of mounting a wiring box comprising: a top plate having an opening; a lid body which opens and closes the opening of the top plate; and a rotating arm, one end of the rotating arm being rotatably supported inside the opening of the top plate and another end of the rotating arm rotatably supporting the lid body, wherein the lid body is elevated while being held in a substantially vertical state inside the opening of the top plate by rotation of the rotating arm, and the opening of the top plate is closed by rotation of the lid body at a surface of the opening of the top plate so that a surface of the top plate and a surface of the lid body form a uniform surface, the method comprising the steps of:
providing, at a lower surface of the top plate, a plurality of mounting holes in a periphery of the opening of the top plate;
providing a plurality of mounting metal fittings in a periphery of the wiring box; and
making a height from the surface of the lid body to the mounting metal fittings to be substantially equal to a height from the surface of the top plate to the mounting holes so that the surface of the top plate and the surface of the lid body form a uniform surface when the wiring box is mounted from below the opening of the top plate.

### Claim 4 (depends on 3)

The method of mounting the wiring box according to claim 3, wherein
the wiring box further comprises:
a slide pin which is provided in the lid body; and
a slide groove which is linked to the slide pin and provided in the wiring box, and the slide groove is configured to include a slide groove to hold the lid body in the substantially vertical state as the lid body is elevated, and a slide groove to guide the lid body to be rotated at the surface of the opening, which are continuously formed.
