PROBLEM TO BE SOLVED: To provide a suspension device that can enhance roll rigidity without deteriorating durability of a seal and ride comfort of a vehicle.SOLUTION: A suspension device 1 comprises a pair of hydraulic dampers DL and DR, a first flow path P1 communicating an extension side chamber EL with a compression side chamber CR and a second flow path P2 communicating a compression side chamber CL with an extension side chamber ER, and accumulators AL and AR. The accumulators AL and AR have cases 10, first free pistons 11 partitioning air chambers G in the cases 10, and second free pistons 12 partitioning the air chambers G into first air chambers G1 and second air chambers G2, respectively. Pressure reception areas at the first air chamber G1 sides are set smaller than pressure reception areas at the second air chamber G2 sides, in the second free pistons 12.SELECTED DRAWING: Figure 1

    【課題】シールの耐久性と車両の乗心地を悪化させずにロール剛性を高めるサスペンション装置の提供等である。【解決手段】本発明のサスペンション装置1は、一対の液圧ダンパDL,DRと、伸側室ELと圧側室CRとを連通する第一流路P1と圧側室CLと伸側室ERとを連通する第二流路P2と、アキュムレータAL,ARとを備え、各アキュムレータAL,ARがケース10と、ケース10内に気室Gを区画する第一フリーピストン11と、気室G内を第一気室G1と第二気室G2とに区画する第二フリーピストン12とを有し、第二フリーピストン12における第一気室G1側の受圧面積を第二気室G2側の受圧面積よりも小さくした。【選択図】図1
