    摘要： A sun gear is supported by an eccentric portion of a rotor via a bearing and rotatable eccentrically to the rotor axis. A ring gear includes inner teeth via which the ring gear is meshed with outer teeth of the sun gear. An output shaft is located adjacent to the sun gear in the axial direction. A fitted portion of the output shaft is loosely fitted to a fitting portion of the sun gear to transfer rotation of the sun gear to the output shaft. The bearing has a center position located in a fitting overlap region between the fitting portion of the sun gear and the fitted portion of the output shaft in the axial direction and/or located in a gear overlap region between the outer teeth of the sun gear and the inner teeth of the ring gear which are meshed with the outer gear.

    摘要： A rotary actuator of the present invention is advantageously used as an actuator in a shift-by-wire system in an automatic transmission. An electric motor and a speed reduction device for reducing a rotational speed of the motor are contained in a housing composed of a front housing and a rear housing. The motor is positioned in the housing at its rear side, and the speed reduction device at its front side. The speed reduction device is composed of a sun gear rotatably supported on an eccentric portion formed on a rotor shaft, a ring gear having inner teeth engaging with outer teeth of the sun gear, and an output shaft loosely coupled to the sun gear for outputting the rotational torque at a reduced speed. The sun gear made of a magnetic material is positioned in contact with an axial end of a stator core of the motor to provide an additional magnetic flux path and thereby to increase an output torque of the motor.
