PURPOSE:To improve the controllability of the posture of a vehicle body by detecting the displacement from the neutral position of a wheel with respect a vehicle body as the torsional quantity of a torsion means and controlling the fluid quantity of an actuator operating fluid to keep a neutral position. CONSTITUTION:As torsion is generated in a torsion bar 2R due to the displacement of a wheel 8R with respect to a vehicle body, a difference in rotation phase occurs in between the shaft control valve 32R and the body valve 35R of a rotary valve 30R in accordance with this torsion quantity. The rotary valve 30R has ports of 30Ra-30Rd, which are connected to an oil pressure source 40, the upper and lower chambers of the cylinder 54R of a power cylinder 50R, and a reservoir 70 respectively. Hence, the operation of the rotary valve 30R feeds oil pressure to the power cylinder 50R in accordance with its operating quantity to keep the wheel in a neutral position with respect to the vehicle body. Thereby, the posture can be favorably maintained. |
