<p>PROBLEM TO BE SOLVED: To provide a sprinkler device capable of preventing a selector valve from malfunctioning owing to hydraulic pressure.SOLUTION: A sprinkler device 1 which has an intake 2 for water, a sprinkling port 5a for sprinkling the taken-in water, and a water flow passage 10 making a connection from the intake 2 to the sprinkling port 5a is provided with a selector valve which is constituted by connecting an upstream member 19 forming a part of the flow passage 10 and a downstream member 23 connected to the downstream side of the upstream member 19 to form a part of the flow passage 10 to each other through screw coupling, and opens and closes the flow passage 10 or changes two or more flow passages by putting the upstream member 19 closer to or away from the downstream member 23 along the screw coupling. In the sprinkler device 1, pressure is applied with the water, passing through the flow passage 10, reversely to the rotating direction in which the downstream member 23 is put away from the upstream member 19 along the screw coupling.</p> |
