Further, since the plurality of types of closed state maintaining means are configured to release the closed state of the first opening / closing door in stages, for example, each closed state maintaining means is opened / closed to open the first opening / closing door. Without applying a force corresponding to the total amount of force that can maintain the closed state of the door at a time, the opening and closing door of the fire hydrant device can be opened using a force smaller than the total amount, and manual It can be opened easily by operation.

  According to the disaster prevention equipment storage device according to attachment 2, since the plurality of types of closed state maintaining means include the first closed state maintaining means having the first magnetic body and the second magnetic body, for example, one magnetic body The magnetic force between the first magnetic door and the second magnetic body makes it possible to reliably maintain the closed state of the first door.

  According to the disaster prevention equipment storage device according to attachment 3, since the plurality of types of closed state maintaining means include the second closed state maintaining means having the first engagement body and the second engagement body, for example, the first engagement The closed state of the first door can be reliably maintained by the engagement between the combined body and the second engaging body (that is, hooking).

  According to the disaster prevention device storage apparatus according to attachment 4, when the first opening / closing door is opened, the first engagement body and the second engagement body are mutually separated after the first magnetic body and the second magnetic body are separated from each other. For example, even when an external force is applied and the first magnetic body and the second magnetic body are separated from each other, the engagement between the first engagement body and the second engagement body is performed. Thus, the closed state of the first door can be maintained, and after the applied external force is removed, the external force is applied by the magnetic force between the first magnetic body and the second magnetic body. It is possible to automatically restore the state before being applied (that is, the state in which the first magnetic body and the second magnetic body are in contact with each other).

  According to the disaster prevention equipment storage device of appendix 5, since the second door can be opened and closed only when the first door is open, for example, the first door and the second door When both of the doors are closed, the closed state of the second door can be maintained by maintaining the closed state of the first door, and the closed state of the second door together with the closed state of the first door Can also be maintained.

  According to the disaster prevention device storage device according to appendix 6, since the first opening and closing door and the second opening and closing door are provided so as to partially overlap each other, for example, by bringing the overlapping portions into contact with each other, When both the first door and the second door are closed, the opening of the second door can be restricted, and the closed state of the second door is maintained together with the closed state of the first door. It becomes possible.

  According to the disaster prevention equipment storage device of appendix 7, the handle for opening and closing the first opening / closing door is at a position corresponding to the position where one closed state maintaining means is provided in the plurality of types of closed state maintaining means. For example, when the user of the disaster prevention device storage device intentionally opens and closes the first opening / closing door using the handle, the first engagement body and the second engagement body are engaged with each other or removed from each other. Therefore, it is possible to reliably transmit the force for opening and closing the first opening / closing door smoothly.
