However, since the conventional equipment storage box has an opening only on the front surface of the main body, a work space for wiring to various devices mounted inside the equipment storage box is narrow, and wiring work is difficult. There was a drawback that it was difficult to remove. In addition, since the rear plate and the side plate of the main body are formed integrally, there is a disadvantage that the installation of a large device storage box is very heavy and the installation work is difficult. In addition, for example, in an equipment storage box in which a wire fixing member is arranged at the upper part of the main body in order to insert a wire from the upper surface of the main body, if it is desired to perform wiring from the lower surface of the main body, the entire equipment storage box must be turned upside down. There was a disadvantage that it had to be done.

[0004]
