A vehicle rear suspension system having a vertically swingable arm connected at the front end swingably to the vehicle body and secured at the rear end to a wheel carrying member which carries a rear wheel for rotation. Three lateral links ar provided and have inward ends pivotably connected to the vehicle body and outward ends pivotably connected to the wheel carrying member. The points of connection of the three lateral links to the wheel carrying member are not aligned in a straight line so that the orientation of the wheel carrying member can appropriately be controlled under bump and rebouncing movements of the rear wheel and under side and longitudinal forces acting on the rear wheel.
