[Problem] To provide a sprinkler head which is installed in a negative pressure sprinkler facility and which has a valve body configured so as to be capable of being separated from a nozzle end with a small force. [Solution] A sprinkler head has a nozzle (6) at one end of the body (1) thereof, and the nozzle (6) can be connected to piping connecting to a water supply source. The outlet of the nozzle (6) is closed by a valve body (3) which is supported by a heat sensitive breakable section (4) which is broken and operated by the heat of fire. A spring (S) provided in the vicinity of the outlet of the nozzle (6) presses a part of the outer periphery of the valve body (3) in the direction in which the valve body (3) is separated from the outlet of the nozzle (6). The spring (S) also presses the valve body (3) in the direction in which the coaxial state between the nozzle (6) and the valve body (3) is released. |
