Abstract: A driving unit for a vehicle includes a transmission, a motor generator and a centrifugal release mechanism. The transmission is employed for transmitting a driving torque outputted from an engine to an output shaft operatively connected to a plurality of driving wheels. The motor generator is connected to the output shaft via a force transmitting mechanism. The motor generator functions as a motor for driving the output shaft in cooperation with the engine when supplied with electric current and functions as a generator when driven by the output shaft. The centrifugal release mechanism is provided at the force transmitting mechanism. The centrifugal release mechanism interrupts a force transmission between the output shaft and the motor generator in a predetermined driving state of the vehicle in which a running resistance applied to the driving wheels exceeds a driving force of the motor generator applied to the driving wheels.
