A body side support member such as the semi trailing arm of a semi trailing type rear-suspension system, the strut of a strut type rear-suspension system and the like is connected to a wheel hub for a rear tire by way of a ball joint and a pair of rubber bushings. The ball joint is positioned, as viewed from the left side of the vehicle body, in quadrant II, one of the rubber bushings is positioned in quadrant IV and the other rubber bushing is positioned in quadrant I or III on a coordinate plane having its origin on the center of the rear wheel, its abscissa on the horizontal line passing through the center of the rear wheel and its ordinate on the vertical line passing through the center of the rear wheel. The other rubber bushing in quadrant I or III is adapted to permit a rotational displacement of the wheel hub about the line connecting said ball joint and said one rubber bushing in quadrant IV, and the central axes of the bushings are directed so that the lower forward part of the rear wheel is adapted to be displaced inwardly with respect to the vehicle body.
