Abstract
An impeller includes a disk section having a tube section with a grip section which is fixed by thermal deformation to a rotary shaft that is configured to rotate around an axis line, and a main disk body, which is on another end in an axial direction from the grip section and which extends outward in a radial direction of the rotary shaft; and blade sections that protrude from the main disk body in the axial direction. The disk section has a hoop stress-limiting section with a tube section which extends further towards the other end in the axial direction than the main disk body.
