Each of the blades of the impeller includes, when a distribution of blade angles of a tip is viewed in a direction in which the tip extends from a tip inlet to a tip outlet for the tip, a constant blade angle region in which the blade angles are constant. A start point on the inlet side of the constant blade angle region is set at a position spaced apart from the tip inlet.
