PROBLEM TO BE SOLVED: To provide a sprinkler head that has simple structure, can be assembled easily, has a constant operation sensitivity, and has the same water spray state as that of a large sprinkler head despite its compact size. SOLUTION: In the sprinkler head for supporting a valve for blocking a water-spraying port with a link mechanism having two arms, first and second gear-lock parts are provided at one arm and the other arm, respectively, and the second gear-lock part is gear-locked to the first gear-lock part. Also, in the sprinkler head where the valve for blocking the water-spraying port descends at the time of operation and is seated at a deflector, a second deflector with the smaller diameter than this deflector is integrated into the valve.
