[0007]

[Effect of the device]

 In the sprinkling nozzle according to the present invention, the entire inner part can be removed from the nozzle body 8 by removing the valve casing 19 from the upper recessed hole 1 as described above, so that the inner part can be easily replaced. In addition, there is a convenient effect that can be easily achieved. Further, in the present invention, since the inner peripheral surface of the upper recessed hole 1 is formed in a straight shape by providing the constricted portion 9 toward the valve casing 19, when the valve casing 19 is removed. In this case, for example, even if the constricted portion 9 unintentionally contains sand or dust, the valve body 19 can be removed by removing the sand and dust, and the nozzle body 8 can be removed. Since the outer shape of the is a hexagonal column, there is an advantage that it can be easily removed with a spanner when removing it from the water supply pipe 28.
