PURPOSE:To open/close a plurality of valves simultaneously by coupling a diaphragm with a shaft body having a plurality of valve bodies, and forming a fluid path for communicating between a control chamber arranged through the diaphragm and a fluid lead-out section of any one valve through the shaft body. CONSTITUTION:A first valve casing 2 having fluid lead-in section 2a and lead- out section 2b and a second valve casing 3 having a lead-in section 3a and a lead-out section 3b are arranged continuously. A diaphragm 4 is stretched over the first valve casing 2 so as to form a control chamber 6. The diaphragm 4 is coupled with a shaft body 10a having a plurality of valve bodies 10b, 10c, while the control chamber 6 and the lead-out section 2b are communicated through a fluid path 16. When a faucet at the downstream side of the lead-out section 2b is opened/closed, pressure in the control chamber 6 communicated with the lead-out section 2b varies to move the shaft body 10a up and down so as to open/close valve seats 2c, 3c through interlocked valve bodies 10b, 10c.
