<p>PROBLEM TO BE SOLVED: To provide a function to stop discharging of water when the connection of a hose is released, and to prevent a backward flow and to reduce water hammering sound. SOLUTION: A sliding member 20, a safety valve 22, and a valve body 24 are provided in this order from a downstream side. The sliding member 20 slides along the inside wall of a cylindrical member 4 to which one end of a hose is connected. The safety valve 22 has a valve part 21 possible to abut from the upstream side on a valve seat part 13 of which one end is connected to this sliding member and is formed inside of the cylindrical member 4. The valve body 24 can be abutted on the valve seat 23 on the upstream side from the downstream side. In addition, an elastic body 25 that is used to energize the safety valve 22 to downstream side, and to energize the valve body 24 to upstream side is provided.</p> |
