Abstract: A main valve unit is rotatably provided in a main valve accommodation space connected to a first opening portion. A fail-safe valve unit is provided in a fail-safe valve accommodation space connected to a second opening portion. The main valve unit controls flow rate of cooling water flowing from the first opening portion to a radiator via a main water passage formed in a housing depending on a rotational position thereof. The fail-safe valve unit is closed when temperature of the cooling water is lower than a predetermined value, to thereby block off flow of the cooling water to the radiator. The fail-safe valve unit is opened when the temperature of the cooling water is higher than the predetermined value, to thereby allow the flow of the cooling water to the radiator. Each of the first opening portion and the main valve accommodation space is fluidically separated from the second opening portion and the fail-safe valve accommodation space by a partitioning wall formed in the housing.
