Description of the Related Art Generally, a panel box such as a distribution panel or a control panel of this type is provided with a back plate which is attached to a wall surface by bending one sheet metal and four surroundings of the back plate. A box-shaped main body with the four side plates, a door frame made by bending a sheet metal attached to the front opening edge of the main body, and a door that is openably and closably attached to the door frame. It is composed of.

ていた。In order to secure the strength of the main body or the door frame, the above-mentioned panel box has a large thickness of the sheet metal constituting the main body, but this causes the main body to become thicker. Alternatively, the door frame, or even the entire board box, becomes heavy, which makes transportation or installation work extremely difficult.

なかった。On the other hand, when the external electric wire is introduced into the board box, since the main body has the four side plates, it is necessary to form the electric wire insertion hole in the side plate. Therefore, in order to facilitate the introduction of the external electric wire, it is also possible to remove the upper and lower side plates in advance and leave the main body in a substantially U-shaped cross section consisting of the back plate and a pair of side plates continuous on both sides of this back plate. However, since the strength of the main body, especially the strength of the pair of side plates, becomes weaker, it is necessary to further increase the plate thickness of the sheet metal, and it has not yet been possible to reduce the weight.
