PURPOSE:To aim at reducing the transmission of vibration from the rear wheel side to the vehicle body side, 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 running condition of the vehicle. 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 is composed of inner and outer cylinders 51, 52 and an elastic ring 53 disposed between both cylinders 51, 52, and gap parts 53a are formed in the elastic ring 53 in part so that the spring constant of the resilient member 5 may be changed in accordance with angles. This resilient member 5 is rotationally displaced by a motor 8 which is controlled by a controller 17 in accordance with the running condition of the vehicle, through a transmission 9, a transmission shaft 10 and the like. |
