PURPOSE:To make improvements in steering stability and a feeling of driving comfortableness, by making a rubber bush, different in a circumferential elastic modulus, rotatable in the circumferential direction, letting it support a suspension arm, and constituting it so as to control a turning position of the bush according to driving conditions. CONSTITUTION:A notch part 11a is symmetrically formed in a rubber bush 11 in a way of changing its phase as far as 180 deg., forming a difference in an circumferential elastic modulus. And, according to driving conditions, a motor 18 is driven, rotating the rubber bush 11 together with an outer tube 14 via a pinion 19 and a rack 17. Then a position of the notch pat 11a of the rubber bush 11 in a bracket 4a (4b) in front and in the rear of a suspension arm 2 is properly controlled. With this constitution, the extent of steering stability and a feeling of driving comfortableness both are improvable. |
