FAUCET DEVICE

PURPOSE:To provide a faucet device in simple structure capable of carrying out water discharging and stopping movement of a water side opening/closing valve and a hot water side opening/closing valve to flow water and hot water. CONSTITUTION:A faucet device 1 discharges and stops water from a primary side flow passage 32 to a secondary side flow passage 42 by opening/closing movement of a valve body 70 of a water side opening/closing valve 10 and discharges and stops hot water from a primary side flow passage 132 to a secondary side flow passage 142 by opening/closing movement of a hot water side opening/closing valve 100. The valve body 70 of the water side opening/closing valve 10 opens and closes by pressure of a water side back pressure chamber 66, and a valve body 170 of the hot water side opening/closing valve 100 opens and closes by pressure of a hot water side back pressure chamber 166. To the water side back pressure chamber 66, water is flown from the primary side flow passage 32 through a communication passage 76, and to the hot water side back pressure chamber 166, hot water is flown from the primary side flow passage 132 through a communication passage 176, but water and hot water of the water side back pressure chamber 66 and the hot water side back pressure chamber 166 are simultaneously discharged through a discharge flow passage 222 by opening movement of an opening/closing valve 200 for operation.
