PROBLEM TO BE SOLVED: To provide a sprinkler nozzle capable of easily executing dismantle work of a shaft constituting a regulating mechanism of jetting volume. SOLUTION: A sprinkler part 2 provided with a valve seat 17 at its inside is opened at a rear side. A water stop shaft 23 having a valve part 25 at the tip is housed at a housing space 18 provided at the rear side of the valve seat 17, and a coil spring 35 is extrapolated to the water stop shaft 23. The housing space 18 is closed by an end cap 20, and a rear end part of the water stop shaft 23 is projected to outside by penetrating the end cap 20. O-rings 31 and 31 are provided between the bearing parts of the water stop shaft 23 and the end cap 20 to ensure watertightness of the housing space 18. The rear end part of the water stop shaft 23 projecting from the end cap 20 is connected to an operation lever 4 by bayonet connection. When the connection with the operation lever 4 is released and the end cap 20 and the operation lever 4 are dismantled, the water stop shaft 23 can be dismantled from the sprinkler part 2.
