An electric vehicle can include a power unit including a speed reduction device coupled to a motor output shaft. Two systems can be provided which are a drive-power transmission path to transmit rotation of a motor to a wheel hub, and a regenerative-power transmission path to transmit rotation of the hub to the motor. A drive-side one-way clutch is provided between the hub and a second internal gear being the final-stage gear in the drive-power transmission path and is configured to transmit rotation of the drive-side final-stage gear to the hub. A regeneration-side one-way clutch is provided between the hub and a regeneration-side first-stage gear and is configured to transmit rotation of the hub to the regeneration-side first-stage gear.
