Beschreibung
Zusammenfassung:	To provide a coolant control valve apparatus using a rotary valve that can suppress involvement of an extraneous material and can rotate a rotor even when such an extraneous material is involved. In an engine cooling system provided with a main channel 4 that connects an engine 1 and a radiator 3, a coolant control valve apparatus 10 that controls a flow rate of coolant water in the main channel 4 has a main valve 11 that is the rotary valve. The main valve 11 includes a rotor 12 and a casing 20 that has an inner peripheral surface facing an outer peripheral surface of this rotor 12, and a gap is provided between the outer peripheral surface of the rotor 12 and the inner peripheral surface of the casing 20. The inner peripheral surface of the casing 20 has a main opening part 30 that is connected to the main channel 4, and this main opening part 30 is provided with a sealing member that protrudes to the outer peripheral surface of the rotor 12 so as to be in touch with the outer peripheral surface of the rotor 12. This sealing member composes a channel that connects an opening part of the rotor 12 and an opening part of the casing 20.
