Abstract
An impeller includes a plurality of pressurizing flow paths defined by a hub, a shroud, and vanes, the pressurizing flow paths being configured to cause fluid to flow in from a shaft direction of a turbine shaft, and cause the fluid to flow out toward an outer side in a radial direction of the turbine shaft, and the pressurizing flow paths being arranged in a row in a circumferential direction of the turbine shaft. Each of the pressurizing flow paths is a through hole having an inlet and an outlet and penetrating from the inlet to the outlet in a linear manner. The inlet is on an end surface of the impeller in the shaft direction of the turbine shaft. The outlet is on an outer circumferential surface of the impeller on an outer side in the radial direction of the turbine shaft.
