Abstract
The present invention relates to a joint structure of a rotor (12) and an output shaft (10) in a synchronous motor, the rotor having an alternate circumferential arrangement of rotor cores (16) and magnets (14). A molding resin (24) is filled and hardened in the gap between the inner circumference of the rotor (12) and the surface of the output shaft (10) so that the components (10, 12) are fixedly jointed together with a high reliability and thus the rigidity of the output shaft (10) is enhanced.
