ABSTRACT OF THE DISCLOSURE In a combination faucet device (10) according to the invention, a movable valve member (160) slidingly moves relative to a main casing (30) to change a mixing ratio of high-temperature water supplied from a hot water port (116) to low-temperature water supplied from a cold water port (106). The movable valve member (160) is pressed by a temperature sensitive spring (130) in a first direction while being pressed by a bias spring (150) in a second direction opposite to the first direction. The temperature sensitive spring (130) is exposed to water mixture and varies its spring constant according to the temperature of the water mixture. The temperature sensitive spring (130) accordingly moves the movable valve member (160) in a direction for decreasing the ratio of the high-temperature water to a certain position where the spring force of the temperature sensitive spring (130) balances with the spring force of the bias spring (150), thus allowing water mixture adjusted to a target.
