PROBLEM TO BE SOLVED: To improve a blowing amount of fluid without increasing manufacturing costs and a number of components.SOLUTION: An impeller changes a direction of gas flowing in from an axial direction of a rotor shaft and causes the gas to flow out. The impeller comprises: a rotary base being fixed to the rotor shaft in the axial direction by a fixed shaft disposed at a central portion and rotating with the rotor shaft as a center; a plurality of partition plates individually having one sides fixed to the rotary base and the other sides facing one sides in the axial direction, being arranged radially from the central portion of the rotary base to an outside in a radial direction and arranged in a circumferential direction at a constant interval with the central portion as a center; and ring-shaped ring bases facing the rotary base and having inclined planes inclined from a central portion side of the rotary base to the outside in the radial direction while being disposed at the other sides of the partition plates. The impeller causes the gas flowing in from the central portion sides of the ring bases in the axial direction to flow out from the radial direction along the inclined planes.SELECTED DRAWING: Figure 1 |
