Claims

[Scope of utility model registration request]

Main springs disposed on the left and right sides of the vehicle body and interposed between the vehicle body and the axle to support the vehicle body load, and fluid springs provided in parallel with each of the main springs, respectively;
Each fluid spring is provided with a supply position for supplying fluid to each fluid spring, a discharge position for discharging fluid from each fluid spring, and a prohibition position for prohibiting supply and discharge of fluid in each fluid spring. a fluid supply/drainage device having a control valve means capable of controlling the vehicle body; and a roll detection means for detecting rolls generated on the vehicle body; under normal conditions, the control valve means is held at the discharge position, and the roll detection means detects the roll. When this occurrence is detected, the control valve means on the fluid spring side on the contraction side with respect to the roll direction of the vehicle body is held in the supply position for a set time, and then held in the prohibition position, and then the roll detection means is used to stop the roll. A suspension device for a vehicle, comprising: a controller that controls the control valve means to hold the control valve means at the ejection position when the end is detected.
