PROBLEM TO BE SOLVED: To provide a sprinkler head and a fixture of the sprinkler head for setting the head in the right direction and reducing the time and labor in the connection in connecting the sprinkler head having rectangular, oval or sartorial sprinkling shape of fire extinguishing liquid where the fixture improves the accuracy of the attaching angle of the sprinkler head. SOLUTION: Plural grooves 1..., whose cross sections are of a same shape, are formed at regular intervals on the flange part 2 of the sprinkler head HA. Pins 11 of a same number and a same shape of the cress section as of the grooves 11 are crested at regular intervals along the entrance part of the bottomed cylindrical fixture 10A with a sprinkling level displayed on he outer surface for connecting the sprinkler head HA to a pipe line. In the engagement part of the sprinkler head HA and the fixture 10A consisting of the grooves 1 and the pins 11, the shape of a part (1a and 11a) of the engagement part is rectangular. Further, an azimuthal magnet 33 is mounted, so that the accuracy of adjusting the angle is improved by comparing the attaching angle and the azimuth.
