In a drive unit for four-wheel drive vehicle that allows a motor for driving front wheels to be easily installed, a torque of an engine is transmitted to a rear wheel axle via a transmission and a rear propeller shaft, and a torque of a front drive motor is transmitted to a front wheel axle via a front propeller shaft. A front drive unit is disposed between the transmission and the rear wheel axle. A case of the front drive unit houses: a main shaft that transmits to the rear propeller shaft an output torque of the transmission; the front drive motor; and a sub-shaft that is disposed in a position shifted in a vehicle width direction with respect to the main shaft and transmits to the front propeller shaft an output torque of the front drive motor.
