PURPOSE:To contrive simplification of structure of the whole of a suspension device, by a method wherein a power unit is formed of an engine and a pair of a right and left speed change gears to be arranged on both sides of the rear of the engine and a casing, which is made into rigid structure, is connected with a car body frame oscillatably. CONSTITUTION:When the titled device is executed on a vehicle wherein a pair of right and left driving wheels Wf, Wf' to be driven by a power unit P and a driven wheel Wr are provided in front of a car body frame F and in the rear of the car body frame F respectively, the powr unit P is formed of an engine E and a pair of right and left belt type automatic speed change gears M, M' to be arranged on both sides of the rear of the engine E. The casing 70 of the power unit P is formed in a rigid body by connecting unitarily a crankcase 50 with transmission cases 71, 71' extended rearward from both the right and left ends of the crankcase 50. Then the casing 70 is connected oscillatably with the car body frame F through the hinge shaft 83 provided on the front end of the car body frame F. |
