ABSTRACT:
A power transmitting apparatus can be configured to switch between 2-wheel drive mode and 4-wheel drive mode and to lock and unlock a differential device. The power transmitting apparatus can comprise an input shaft connected to a driving power source i.e. an engine of vehicle and rotated around one rotational axis, a pair of output shafts of left and right sides for driving front wheels or rear wheels of vehicle when driving force is transmitted from the input shaft, a differential device arranged between the input shaft and the output shafts for absorbing the difference of rotation between the output shafts by differential action thereof, an operational shaft for performing connection and disconnection between the input shaft and output shafts by connecting and disconnecting the input shaft and the output shafts and also performing locking and unlocking of the differential means, a driving means for arbitrarily driving the operational shaft, and a case mounted on a vehicle and containing the differential means and the operational shaft characterized in that the input shaft extends from a rear side of the case facing toward the engine substantially in parallel with the operational shaft; and that the driving means is arranged on the rear side of the case.
