This electric motor of the present invention is formed by an inner circumferential side rotor, an outer circumferential side rotor, and a planetary gear mechanism that are placed coaxially. The planetary gear mechanism is a single pinion type that includes a first planetary gear train and a second planetary gear train that are each single gear train. A first planetary carrier that supports the first planetary gear train is able to pivot around an axis of rotation, and a second planetary carrier that supports the second planetary gear train is fixed to a stator. The electric motor is further provided with an actuator that pivots the first planetary carrier by a predetermined pivot amount around the axis of rotation.
