To provide a drive unit of an electric motor-type four-wheel-drive car, which can achieve efficient transmission of a driving force of an electric motor and an improvement in steering property.SOLUTION: A drive unit of an electric motor-type four-wheel-drive car comprises two electric motors, two differential mechanisms, first-eighth connection/disconnection mechanisms, and a sprocket mechanism. Driving forces from the electric motors are distributed and transmitted independently on the right and left sides to front and rear wheels via the connection/disconnection mechanisms, the connection/disconnection states of which are controlled, the sprocket mechanism, and the differential mechanisms. Thereby, torque vectoring is achieved on the right and left sides while differential functions for the front and rear wheels are fulfilled.SELECTED DRAWING: Figure 1
