  However, in such a conventional disaster prevention equipment storage device, since the frame is formed inside the opening and closing door, the back plate is disposed thereon, and the recess is formed in a part of the back plate. There is a problem that the door becomes thick, the structure is complicated, the weight is increased, and the entire device is enlarged.

An object of the present invention is to provide a disaster prevention equipment storage device having a door structure that can be reduced in size and thickness without impairing strength.

The present invention relates to a disaster prevention device storage device including a housing and an opening / closing door that is openably / closably attached to the front surface of the housing.
The open / close door is characterized in that a bent portion is formed by turning the periphery 180 degrees inside.

Further, the open / close door forms a standing edge portion with one opposite edge rising inward and the bent portion where the other opposite edge is turned inward by 180 degrees.
Furthermore, the disaster prevention equipment is provided in the inner space of the open / close door partitioned by the standing edge.
As a fire hydrant device, the disaster prevention device accommodating device accommodates a nozzle holding portion that holds a water discharge nozzle in an inner space of an opening / closing door partitioned by a standing edge portion.
