Beschreibung
Zusammenfassung:	The invention provides a power distribution device for an electric vehicle, which can distribute power larger than power of front wheels to rear wheels and obtain stable vehicle behavior during braking. This power distribution device for an electric vehicle is mounted on an electric vehicle provided with front wheels, rear wheels, an electric motor for outputting power for travel, and a mechanical brake for applying braking force to at least the front wheels. Furthermore, the device is provided with: a power distribution mechanism that distributes power output from the electric motor to the front wheels and the rear wheels; and a controller that controls the power distribution mechanism, the power distribution mechanism including: a first clutch capable of fixing a power distribution ratio during straight movement to a first distribution ratio; and a second clutch capable of fixing the power distribution ratio during straight movement to a second distribution ratio, and the controller sets the second clutch t
