PURPOSE:To enhance the durability etc. and balance the car weight through placing of differential gearing devices parallelly in specified positions by connecting a plurality of differential gearing devices by a plurality of switching means selectively with possibility of torque transmission, and eliminating use of any clutching device. CONSTITUTION:A speed changer 1 is installed across in the front part of a car body, and in-the-cabin ends of a pair of front wheel accelerator shafts 2a, 2b, on the left and right, are coupled with a front differential 3. Torque of said speed changer 1 is converted to right angle by a direction changing member 5, and a transmission shaft 8 stretching for and aft of the car body is coupled with the output side. On this transmission shaft 8, a plurality of differential gearing devices 9, 10 each consisting of simple planet gear are installed concentrical to the transmission shaft 8 and in parallel with each other. No.2 differential gearing device 10 is coupled with said differential 3 through No.1 switching means 17 etc., while No.1 differential gearing device 9 with said differential 3 through No.2 switching means 19 etc.
