    flow rate adjusting means for supplying or discharging the operating fluid to or from the cylinder unit;

    roll controlling means for generating a control value to the flow rate adjusting means so as to allow an actual angle of a roll of the vehicle body to agree with a target angle of the roll of the vehicle body;

    inner-pressure detecting means for detecting an inner pressure of the cylinder unit;

    cornering detecting means for detecting cornering of the automotive vehicle; and

    correcting means for correcting the control value so as to make a quantity of the operating fluid to be supplied or to be discharged become smaller as the inner pressure detected by the inner pressure detecting means becomes larger, when the cornering of the automotive vehicle is detected by the cornering detecting means.
