とから構成する事を特徴とする水栓装置。 Opposing the upstream side of the water flow channel to a valve hole provided at an appropriate location in the water flow channel, a valve body is disposed to open and close the valve hole and define a pressure chamber, and a pressure chamber is formed approximately at the center of the valve body. A pore is bored to communicate with the downstream side of the valve hole of the water passage, and the pressure chamber is communicated with the upstream side of the valve hole of the water passage through a bypass passage, and the pore is driven by a motor. In the case of a needle valve that opens and closes with a needle valve, a valve shaft is used to drive the needle valve from the outside in the axial direction, and an elastic body is attached to the tip of the valve shaft so that it is always biased in the direction of closing the pores. A faucet device characterized by comprising a needle.
