Claims

[Claims for Utility Model Registration] A plurality of stepped gears that transmit the driving force of a motor to an output gear, and a return spring connected to the side end of the output gear so that the outer circumference of the output shaft is idling in the OFF state and the output gear is in the ON state. a clutch device that variably controls attraction torque using an excitation current of a clutch coil to couple the output gear to an output shaft and transmit motor torque to the output shaft when in a state; and a load driving wire fixed to one end of the output shaft. a rotary lever for driving the clutch, and the clutch device includes a yoke that houses the clutch coil and is fixed to the frame;
An electric drive device comprising a first clutch plate that is rotatably attached to the yoke and forms a magnetic path with the yoke, and a second clutch plate that is attached to the side surface of the output gear so as to be movable in the axial direction. , the yoke containing the clutch coil is integrally formed with a frame for assembling the electric drive device, and the frame has an expanded outer periphery to serve as a mounting plate. Electric drive device.
