An actuator for adjusting a height of the vehicle body is provided for each of the wheels and the height of the body is adjusted for each of the wheels by supplying and discharging an operating fluid to and from the actuator. A vehicle-height detecting sensor is also provided on each wheel for detecting the height of the vehicle body and for control over a posture of the body, namely, control over a supply or discharge of the operating liquid to or from the actuator is implemented with respect to bouncing, pitching or rolling of the body on the basis of output from the vehicle-height detecting sensor. Furthermore, a plurality of vertical G sensors for detecting acceleration in a vertical direction are provided to sense bouncing, pitching and rolling components of acceleration in the vertical direction, and the posture control utilizing the vehicle-height sensor is corrected so as not to make the vertical acceleration for the three components larger. Three vertical G sensors are provided so as to define a virtual plane representing the body, and that, for instance, two of the three vertical G sensors are disposed on the front portion of the body at positions bilaterally symmetrical to each other and one thereof is disposed on the rear portion thereof at a middle position, thereby allowing the three vertical G sensors to enable a detection of the acceleration in the vertical direction with respect to the bouncing, pitching and rolling components.
