Claims

[Scope of utility model registration request]

A suspension unit is provided for each wheel and has a fluid spring chamber, and when a roll occurs, fluid is supplied to the fluid spring chamber of the suspension unit on the sinking side, and fluid is supplied from the fluid spring chamber of the suspension unit on the floating side. In a suspension device that suppresses roll of the vehicle body by discharging the vehicle body, there is provided a roll occurrence state detection means for detecting a roll occurrence state, and a roll control amount corresponding to the roll occurrence state detected by the roll occurrence state detection means. a roll angle change switch for changing the roll angle; a roll control means for controlling the roll according to the roll control amount stored in the storage means; and a roll control means for controlling the roll according to the state of the roll angle change switch. An electronically controlled suspension device comprising means for changing a roll angle by increasing or decreasing a control amount.
