ABSTRACT:
In a motor-powered drive device for controlling, for example, a throttle valve of an internal combustion engine, a reduction gear mechanism is separated from an electromagnetic clutch mechanism by a base plate and magnetic flux leakage to portions other than the clutch mechanism is prevented by non-magnetic members. A one-way clutch is provided for preventing buckling of return springs.
