Abstract
An impeller and a rotary machine include an inner diameter portion, a disk portion, a blade portion, and a cover portion. The disk portion includes a main body portion adjacent to the blade portion, and a fixing portion disposed at a radially inward side of the main body portion and fitted at a radially outward side of an outer peripheral surface of the inner diameter portion. The fixing portion is formed so as to protrude from the main body portion toward another side in an axial direction.
