Abstract
In a state where the edge of the second duct wall on the suction port side is referred to as a point P, a point on the outer peripheral surface of the first rotatable member closest to the second duct wall is referred to as a point U, a point at which a straight line passing through the point P and a rotation center O of the first rotatable member intersects with the outer peripheral surface of the first rotatable member is referred to as a point Q, and in a state where the direction of Fθ is the same direction as the rotation direction of the first rotatable member, the sign of Fθ is positive, Fθ < 0 is satisfied in a range from the point Q to the point U with respect to the rotation direction of the first rotatable member.
