To provide a vehicle in which a trunnion suspension is installed straddling over a driving shaft and a driven shaft, whereby the grounding load of each driving wheel is enlarged certainly using a low-cost and lightweight construction.

When a vehicle is empty, a leaf spring 5 of a trunnion suspension 15 is in contact with the oversurface of a driving shaft axle housing 8, while the tail of the leaf spring 5 is detained with the bend 21 of a bracket 20 fixed to a side frame 1, wherein a minor gap 23 is reserved between the oversurface of driven shaft axle housing 10 and the leaf spring 5. When the car is loaded, the vehicle height is sunk by deflection of the leaf spring 5, which contacts with the oversurface of the driven shaft axle housing 10.
