ABSTRACT:
In an assembly for a vehicle of an engine and a four wheel drive power transmission system including a speed change device, a first power distribution device for rotationally dividing rotational power for the pair of either the front wheels or the rear wheels, wherein the engine, the speed change device and the first power distribution device are assembled in this order along a common central axis with one of two output shafts of the first power distribution device being shifted sideward of the central axis and directed toward the engine while the second power distribution device is mounted to a side of the engine with an input shaft thereof being directed toward and substantially aligned with the output shaft of the first power distribution device. A propeller shaft to connect the output shaft of the first power distribution device with the input shaft of the second power distribution device is firmly mounted at one end thereof to the output shaft of the first power distribution device to be supported and driven thereby and rotationally coupled at another end thereof with the input shaft of the second power distribution device by a splined sleeve engagement. Intermediate portion of the propeller shaft is rotatably supported by a radial bearing mounted to the speed change device.
