Zusammenfassung:	The invention provides a power device in which a rotation restricting mechanism can make a force for maintaining wheels small in a stop state and the rotation restricting mechanism can be reduced in size. The power device includes an electric motor that drives a left wheel and a right wheel of a vehicle; a transmission that is disposed on power transmission paths between the electric motor and theleft wheel and between the electric motor and the right wheel; and a differential gear system that distributes output power shifted by the transmission to the left wheel and the right wheel. The transmission includes a first gear that is mechanically connected to the electric motor; a second gear that is mechanically connected to a differential gear casing of the differential gear system; and a plurality of pinion gears that mesh with the first gear and the second gear. The plurality of pinion gears are supported to be capable of rotating and not to be capable of revolving. One pinion gear out of the plurality of pin
