A valve unit 14 is disposed in the middle of a water channel W connecting the water spray port 27 and the connection port 3. The connection port 3 is inserted into the water pipe 4 to constitute the projection side of the recess and projection connection. By providing the connection port 3 with the lower part of the valve unit 14 in proximity thereto, the lower part of the valve unit 14 is eventually inserted into the water pipe 4, and the length portion and the like inserted into the valve unit 14 can be made lower in the mounting state of the sprinkler nozzle.
