Abstract
A rotor of an electric motor is provided in which a permanent magnet holding member can be assuredly fixed to a rotor main body and the rotor main body can be easily worked and inexpensively manufactured. In the rotor, a plurality of permanent magnetsare held in a permanent magnet holding membermade of a synthetic resin and fixed to an outer peripheral part of a cylindrical rotor main body. An outer peripheral surface of the rotor main bodyis a cylindrical surface. Rotation prevention recessed partsare formed at a plurality of parts in the circumferential direction of the outer peripheral part in both end parts of the rotor main body. The permanent magnet holding memberincludes annular partswhich come into close contact with the outer peripheral parts of both end faces of the rotor main bodyand connecting partswhich connect both the annular partson the outer peripheral surface of the rotor main bodyand hold the permanent magnets. A plurality of rotation prevention protruding partsfitted to the rotation prevention recessed partsof the rotor main bodyare formed integrally with the permanent magnet holding member
