Abstract
An impeller includes a disk formed in a disk shape about an axis, and a plurality of blades provided at intervals in a circumferential direction on one side in the axial direction of the disk. The blades define a flow path extending from one side in the axial direction toward a radial outer side and include a low-rigidity region and a high-rigidity region. The low-rigidity region has an inlet, an outlet of the extending region of the flow path, a relatively small plate thickness, and has a relatively small inclination angle with respect to the disk. The high-rigidity region adjacent to the low-rigidity region has a relatively large plate thickness, and a relatively large inclination angle with respect to the disk.
