PURPOSE:To improve tack-in restraining effect by providing liquid enclosed cylinders responding to the displacement, in the direction of a swinging axis, of a suspension arm, and by connecting the liquid enclosed cylinders of left and right steering wheels to each other by means of a crossing piping. CONSTITUTION:During turning traveling, when transverse force Fs is applied to rear wheels 1L, 1R, swinging axes 5L, 5R directional force FSL, FSR, caused by the transverse force Fs, and applied to suspension arms 3L, 3R are liable to displace the suspension arms 3L, 3R toward the respective correspondent swing axes through the elastic deformation of elastic bushes 4L, 4R. At this time, on account of the directions of the force FSL, FSR, high pressure is produced in the chambers 21L, 21R of the liquid enclosed cylinders 15L, 15R. Neverthless, as both chambers 21L, 21R are communicated with each other by means of a crossing piping 25, the displacement of liquid is not generated. Consequently, displacement in the direction of swing axes is inhibited. Due to this construction, large tack-in restraining effect can be obtained. |
