[Problem] To completely close the space between the hot-water valve 3 a and the hot-water valve seat a when ejecting the cold water, without increasing the size of the temperature-sensitive coil spring 5 constituted by the SMA spring. [Solution] In a hot water-water mixing faucet for holding a control valve body 3 in a balanced position between two springs, a bias spring 4 and a temperature-sensitive coil spring 5 , and moves an adjusting screw 6 a, which supports the bias spring 4 , in an axial direction to change setting of the supporting position of the bias spring 4 , a rear end side of the bias spring 4 is supported by a supporting member g which is formed separately from the adjusting screw 6 a, the supporting member g is slidably inserted in the axial direction into a through-hole 63 provided on the adjusting screw 6 a and is connected detachably to the adjusting screw 6 a by means of an abutting section t 1 provided in an area protruding from the through-hole 63 toward the bias spring 4 side, and a lifting spring 7 , which biases the supporting member g to pull the supporting member g back toward the side opposite to the bias spring 4 to the adjusting screw 6 a, is provided between an area protruding from the through-hole 63 toward the side opposite to the bias spring 4 and the adjusting screw 6 a.
