PROBLEM TO BE SOLVED: To provide a device in which water release/water stop is switched reliably by input to an operation section regardless of a position of a water release head and further, a main valve element can be opened/closed reliably while improving portability or assemblability of the device per se.SOLUTION: A connection member 90 incorporates a pilot channel 98, a pilot valve seat 95 and a pilot valve element 94. The pilot channel 98 is communicated with a pressure release channel 43 in the state where the connection member 90 is connected to a main valve unit 40, and guides water flowing from the pressure release channel 43 to a channel inside of the connection member 90. The pilot valve seat 95 is provided in the pilot channel 98. The pilot valve element 94 is provided at the side of the other end 7b of a wire 7 and moved in accordance with forward/backward movement of the wire 7 to open or close the pilot valve seat 95. The wire 7 is disposed within a water release head, within a hose and within the connection member 90 from one end side of the wire 7 to the other end 7b side. |
