<p>A magnet holding structure of a rotor, wherein a rotor core (2) having a first base (3) and magnets (5) assembled integrally with each other is inserted into a rotor (1) and each part is fixed axially by the crimped portion (1a) of a rotor unit through a second base (4), the engaging projected parts (1b) of the rotor unit are engaged with the engaging recessed parts of a first support body to fit the first support body in rotating direction, the locking pieces (3b) of the first support body are engaged with partition walls (2b) for partitioning the magnet (5) receiving axial holes (2a) of a rotor core unit to fit the rotor core unit in rotating direction, and the working errors of the axial heights of the rotor core unit and the magnets are absorbed by the flexible projection of the first support body, whereby the magnet holding structure of the rotor can be realized without using an adhesive agent, and a production cost can be reduced since adhesive agent coating and drying processes are not required.</p> |
