The fire shutter 10 includes a shutter curtain 12 which is configured by juxtaposing a plurality of slats 12a, and a sprinkler head 50 which is disposed on the periphery of an area above the shutter curtain 12 so as to sprinkle water on the shutter curtain 12. A downflow water screen can be formed by sprinkling water on a first compartment-side lateral surface of the shutter curtain 12, of both lateral surfaces of the shutter curtain 12, from the sprinkler head 50. |
