PROBLEM TO BE SOLVED: To provide a sprinkler head with a spring for separating a valve body from a nozzle end, wherein the spring can be prevented from being stuck to a deflector etc. and being an obstacle of water sprinkling.SOLUTION: A sprinkler head comprises: a body 1 in which one end of a hollow nozzle 11 can be connected to piping P continuing to a water supply; a heat-sensitive disassemblable unit 5 which is engaged with the front end of a frame unit extending from the vicinity of an exit of the nozzle 11 to a water splashing direction, and is to be disassembled due to heat and works in case of fire; a valve body 13 which is supported by the heat-sensitive disassemblable unit 5, and closes the nozzle 11; a spring D which is arranged near to the exit of the nozzle 11, and separates the valve body 13 from the nozzle 11; and a deflector 6 which is arranged on the extension of the nozzle 11 and allows water discharged from the nozzle 11 to collide and be splashed in all directions. In the sprinkler heat, the spring D and the valve body 13 are bonded to each other with an adhesive sheet 16, and the valve body 13 is equipped with a deflection unit formed to protrude closer to the side of the heat-sensitive disassemblable unit 5 than to a surface supported by the heat-sensitive disassemblable unit 5. |
