The flow hole forming portion is fixed at the passage and includes: a plurality of flow holes, each of which is configured to conduct the fluid; and at least one partition which is placed between corresponding adjacent two of the flow holes. The rotor includes a passage opening and a closing portion. The at least one partition of the flow hole forming portion has: a parallel portion which extends in parallel with a radial direction of an imaginary circle centered on a rotational axis; and a progressively varying portion which is placed on an outer side of the parallel portion in the radial direction. A width of the progressively varying portion measured in a circumferential direction is progressively increased toward the outer side in the radial direction.
