description 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).
