[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box used for a distribution board, a control board, and the like.

[0002]

2. Description of the Related Art Conventionally, this type of box has a box-like body having a bottom piece and a four-side piece, each of which is open on one side, and a lid for opening and closing the opening of the box. To pivotally attach the lid to the opening edge of the box, one side of the hinge is fixed to a fixing member fixed to the bottom piece of the box, and the other side of the hinge is fixed to the lid. Do it.

[0003]

According to the above-mentioned box, in order for the lid to be rotatably attached to the opening edge of the box, one of the hinges is attached to a fixing member fixed to the bottom piece of the box. Since the side is fixed and the other side of the hinge is fixed to the lid, there is a possibility that the fixing member may interfere with wiring work such as a breaker in the box.

In order to solve this problem, it is conceivable that one side of the hinge is fixed to the side of the box and the other side of the hinge is fixed to the lid, but in this case, the hinge becomes an obstacle. Care must be taken so that the opening of the box cannot be closed with the lid, and the work of fixing the lid to the box becomes cumbersome.
