Abstract
A hypocycloid reducerfor reducing rotation of a flat motorto output the speed-reduced rotation to a drum is provided between the drum and the flat motor, a rotor shalt memberwhich is rotated with the same rotation number as the flat motoris axially aligned with the drum is provided on the same side as the flat motor. An output rotation bodyfor outputting the speed-reduced rotation is axially aligned with the drum and provided on the same side as the drum. Since the rotor shaft memberand the output rotation bodyare axially aligned with the drum, turning force can be transmitted bi-directionally between the rotor shaft memberand the output rotation body. Therefore, it is possible to eliminate an electromagnetic clutch to reduce the driving apparatus in size and weight, and since wires and control logic of the electromagnetic clutch are not needed for the driving apparatus, the driving apparatus can be reduced in production cost.
