PROBLEM TO BE SOLVED: To obtain a driver capable of enhancing smoothness of rotation furthermore.SOLUTION: In a driver 1 including a motor 30, and an eccentric swing reduction gear 10 having a crankshaft (input shaft) 18 provided with eccentric bodies 20, 22, the motor has a rotor 40 provided on the crankshaft and rotating integrally with the crankshaft, and a stator 50 arranged while providing a gap δ30 between the rotor and the stator 50. In a state where the crankshaft is not deformed, the suction force generated between the rotor and stator when energizing the motor, is differentiated depending on the circumferential position. |
