To thin a housing box, narrow an installation space, and enlarge a freedom degree of an installation place in a fire extinguishing facility comprising a fire extinguishing agent container, a gas cylinder for pressurizing, and an emission hose connected to the fire extinguishing agent container at one end.

Fire extinguishing agent for one conventional large-diameter fire extinguishing agent container is parted and charged into plural fire extinguishing agent containers 2. An outer diameter of each fire extinguishing agent container 2 can thus be reduced while securing necessary fire extinguishing agent quantity. The shorter diameter fire extinguishing containers 2 are housed and disposed parallel in a lateral line in a housing box 1, so a depth size of the housing box 1 can be reduced and thinned. A gas cylinder 3 for pressurizing is set in a lateral attitude and housed and disposed above the fire extinguishing agent containers 2, thereby a width size of the housing box 1 can be small, with a height of the housing box 1 restricted to the lowest possible.
