Abstract
To provide a sprinkler head in which the amount of water sprinkled in a direction in which a pin supporting a deflector is provided is increased. Included are: a body having a nozzle through which a fire-extinguishing liquid is discharged; a disk-like deflector that sprinkles the fire-extinguishing liquid discharged from the nozzle outward in a direction intersecting the axis of the nozzle; and a support that supports the deflector. A nozzle-side surface of the deflector has a recess extending from a portion around the support toward an outer edge of the deflector and recessed into the nozzle-side surface of the deflector. First slits are provided on both sides of the recess in the width direction such that open ends are adjacent to the outer edge of the recess.
