Further, since the lid only needs to be able to seal only the opening at the upper part of the container body, the lid can be made lightweight and can be easily opened and closed. By opening the lid and pulling the equipment body upward from the opening, maintenance and inspection can be easily performed.

Further, if a rail extending in a substantially vertical direction is provided in the container main body and the equipment main body can be pulled out from the opening along the rail, the equipment main body can be stably pulled out. The operation of pulling out the equipment body can be easily performed.

[0010] Further, if the equipment body is provided with a grip portion for pulling out upward, the equipment body can be easily pulled out by grasping the grip portion.

Further, if a dehumidifier for dehumidifying the inside of the container main body is provided, dew condensation and the like in the container main body can be prevented, and the life of the apparatus main body can be extended.

[0012] Further, if the dehumidifying port of the dehumidifier is provided at the lower part of the container main body outside the container main body, even if the hole in which the equipment is buried is submerged, the moisture discharging port is connected to the container main body. Inundation can be prevented. Furthermore, even when the lower part of the container main body is open, it is possible to prevent the moisture release port from forming an air hole and to be flooded from the opening at the lower part of the container main body.

Further, if a desiccant is provided in the container body, electric power for operating the dehumidifier is not required, and a temperature rise in the container body due to the heat of operation of the dehumidifier can be prevented.
The inside of the container body can be dehumidified, thereby preventing dew condensation and the like in the container body and extending the life of the apparatus body.

Further, if the container main body has a bottom portion for sealing the lower part, the hole in which the equipment is buried is submerged, and the container main body is exposed to a strong water flow or a large water pressure is applied. Also, it is possible to prevent water from entering the container body.

If the operation panel of the equipment main body is arranged on the ground part outside the container main body, operations such as changing settings of the equipment main body can be easily performed from the ground part.
