Abstract

An electric-rotating-machine rotor has a rotor core in which ring-shaped plate materials that are each magnetic materials are stacked in an axial direction and a shaft-press-fitted into an inner circumferential surface of the rotor core; the inner circumferential surface has a first press-fitting portion that is an axial-direction section into which the shaft is inserted and a second press-fitting portion that is an axial-direction section adjacent to the first press-fitting portion and into which the shaft is inserted with an interference larger than that of the first press-fitting portion, and the shaft is press-fitted into the inner circumferential surface of the rotor core from the first press-fitting portion side. As a result, the electric-rotating-machine rotor in which no gap is caused between the stacked plate materials can be realized at low cost. Moreover, it is made possible to produce the electric-rotating-machine rotor through simple processes and at low cost.
