Abstract: A valve, which is rotated about a rotational axis, includes a valve outer peripheral portion. The valve outer peripheral portion has a valve inflow port for supplying fluid to a flow passage of the valve outer peripheral portion and valve outflow ports for discharging the fluid from the flow passage. The valve outflow ports include: a main outflow port which is configured to communicate with a whole of a seat opening of a valve seat; and a plurality of intermediate outflow ports, each of which is configured to communicate with a portion of the seat opening. An axial dimension of each intermediate outflow port, which is measured in an axial direction of the rotational axis, is smaller than an axial dimension of the seat opening, which is measured in the axial direction. The axial dimension of each intermediate outflow port is progressively changed in a circumferential direction.
