Abstract
A driving system includes an electric motor, a transmission apparatus, a differential apparatus and a brake. The differential apparatus includes an input portion coupled to an output portion of the transmission apparatus, a pair of output portions, and a differential device that allows differential rotation of the pair of output portions. A brake is provided in a drive path from an output portion of the electric motor to the input portion of the differential apparatus. The differential apparatus includes a clutch member movable between a first position in which a differential rotation of the differential device is allowed and a second position in which the differential rotation of the differential device is stopped, a clutch actuator that moves the clutch member to the first position, and a holding portion that holds the clutch member to the second position when the clutch actuator is in a non-operating state.
