Abstract
In a 4WD vehicle that is basically an FF type, a propeller shaftincludes, on a front end and a rear end thereof, respective driving force transmission devicesand. The propeller shaftincludes an electric motor, and when the electric motoris rotated in a backward direction of the vehicle during a 2WD state, a hypoid ring gearof a transfer mechanismof the driving force transmission deviceis moved so as to engage a clutch mechanism. By such an engagement, engine torque is transmitted to the driving force transmission devicevia the propeller shaft. Thus, a hypoid ring gearof a transfer mechanismof the driving force transmission deviceis moved so as to engage a clutch mechanism. Accordingly, a drive state is switched to a 4WD state.
