Abstract:
The present invention comprises a permanent magnet ( 13 ) that is disposed around a rotor shaft ( 11 ), a retaining ring ( 14 ) that is press-fitted around the outside of the permanent magnet ( 13 ) from one end of the rotor shaft ( 11 ) so as to retain the permanent magnet ( 13 ) against the rotor shaft ( 11 ), and an end plate ( 12 ) that is provided adjacent to the permanent magnet ( 13 ) in the axial direction of the rotor shaft ( 11 ) and guides the press-fitted retaining ring ( 14 ), maintaining planar contact with the inner circumferential surface thereof, toward the permanent magnet ( 13 ) while causing the retaining ring ( 14 ) to expand as the retaining ring ( 14 ) progresses from one end of the rotor shaft ( 11 ) to the other end of the rotor shaft ( 11 ). Concentration of stress on the retaining ring ( 14 ) during press-fitting can thus be minimized.

Claim (Index 10):
A rotor for a permanent magnet rotary electric machine comprising:\n a permanent magnet disposed on an outer peripheral surface of a rotor shaft; a retaining ring press-fitted to an outside of the permanent magnet from one end portion side of the rotor shaft to retain the permanent magnet on the rotor shaft; and a ring guide portion provided adjacent to the permanent magnet in an axial direction of the rotor shaft, the ring guide portion configured to come into surface contact with an inner peripheral surface of the press-fitted retaining ring and guide the retaining ring toward the permanent magnet while gradually increasing a diameter of the retaining ring as the retaining ring is moved from the one end portion side of the rotor shaft toward another end portion side of the rotor shaft.
