A suspension device (S) is provided with a fluid pressure circuit (FC) between a damper (D), a pump (4), and a reservoir (R). The fluid pressure circuit (FC) is provided with: an extension-side damping valve (15) provided to an extension-side passage (7); a pressure-side damping valve (17) provided to a pressure-side passage (8); a pressure difference control valve (9) that controls the pressure difference between the extension-side passage (7) and the pressure-side passage (8); an intake passage (10) that connects the interval between the pressure difference control valve (9) and a supply-side check valve (12) in a supply path (5) with a discharge path (6); and an intake check valve (11) that is provided to the intake passage (10) and that allows only the flow of a fluid from the discharge path (6) toward the supply path (5). 悬架装置(S)包括设于阻尼器(D)、泵(4)以及储液器(R)之间的流体压回路(FC)，流体压回路(FC)具有设于伸长侧通路(7)的伸长侧阻尼阀(15)、设于压缩侧通路(8)的压缩侧阻尼阀(17)、用于控制伸长侧通路(7)与压缩侧通路(8)的压力差的压力差控制阀(9)、连接供给路径(5)的压力差控制阀(9)和供给侧单向阀(12)之间与排出路径(6)的吸入通路(10)、以
