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.COPYRIGHT: (C)2014,JPO&INPIT【課題】水圧による切換弁の誤作動を防止することができる散水装置を提供する。【解決手段】水の取り入れ口2と、取り入れた水を散水する散水口5aと、取り入れ口2から散水口5aまでを接続する水の流路10とを有する散水装置1において、流路10の一部を形成する上流側部材19と、この上流側部材19の下流側に接続され流路10の一部を形成する下流側部材23とをネジ結合で連結してなり、上流側部材19を下流側部材23に対し上記ネジ結合に沿って接近離間させることにより流路10の開閉または二つ以上の流路の切り換えを行う切換弁を設け、かつ、流路10を通過する水によって、上記ネジ結合に沿って下流側部材23を上流側部材19から離間する際の回転方向と逆回りの方向に加圧する。【選択図】図2
