PURPOSE:To improve transmission efficiency, by a method wherein a differential case of a differential gear is connected with an output shaft transmitting power to a pair of a right and left driving wheels and belt type automatic speed change gears are provided respectively on shafts extending from both sides of the differential gears. CONSTITUTION:An output shaft 21 of an engine E of a vehicle wherein a power unit P including the engine E is fixed at the front edge of a vehicular body frame F rockably centering around a hinge shaft 83 is formed into a hollow shaft into which inner edge parts of input shafts 52 of a right and left belt type automatic speed change gears M are inserted. Both the input shafts 52 are connected with an output shaft 21 through a differential gear Df obtained by forming a differential case 53 on an intermediate part of the output shaft 21 unitarily. The right and left automatic speed change gears M are connected in parallel with the output shaft 21 of the engine E through the differential gear Df. Then output shafts 61 of the automatic speed change gears M are connected with a right and left driving wheels Wf. |
