Provided is a suspension device capable of improving roll stiffness without deteriorating the durability of a seal and the riding comfort of a vehicle. A suspension device (1) of the invention includes: a pair of liquid pressure dampers (DL) and (DR); a first passage (P1) which communicates the extension side chamber (EL) with the compression side chamber (CR); a second passage (P2) which communicates the compression side chamber (CL) with the extension side chamber (ER) ; and accumulators (AL) and (AR), in which each of the accumulators (AL) and (AR) includes a casing (10), a first free piston (11) which defines a gas chamber (G) inside the casing (10), and a second free piston (12) which defines a first gas chamber (G1) and a second gas chamber (G2) inside the gas chamber(G), and a pressure receiving area near the first gas chamber (G1) in the second free piston (12) is set to be smaller than a pressure receiving area near the second gas chamber (G2) .
