PURPOSE:To aim at reducing vibration through a vehicle body, by enabling the spring constant of a resilient member which is disposed in the vehicle attaching end part of a radius rod for bearing a longitudinal load acting upon each rear wheel, to be changed, with respect to the load input direction, in accordance with the vehicle speed or the engine rotational speed. CONSTITUTION:The base end part 41 of a radius rod 4 whose front end is attached to the front end part of a suspension arm 2 which supports a rear wheel 1, is swingably attached to a vehicle body side member in the front or rear of the rear wheel through a resilient member 5. With this arrangement it is possible to bear a longitudinal load acting upon the wheel 1. In this arrangement, the resilient member 5 has an elastic ring 53 disposed between both inner and outer cylinders 51, 52 and formed in a part thereof with gap parts 53a so that the spring constant of the resilient member 5 is rotationally displaced by a motor 8 which is controlled by a controller 17, through a transmission 9, a transmission shaft 10 and the like so that the spring constant of the resilient member may be changed in accordance with the vehicle speed or the rotational speed of the engine. |
