Abstract: There is provided a suspension device capable of improving roll stiffness without deteriorating the durability of a seal and the riding comfort of a vehicle, the suspension device including: a pair of liquid pressure dampers; a first passage which communicates the extension side chamber with the compression side chamber; a second passage which communicates the compression side chamber with the extension side chamber; and two accumulators, in which each of the accumulators includes a casing, a first free piston which defines a gas chamber inside the casing, and a second free piston which defines a first gas chamber and a second gas chamber inside the gas chamber, and a pressure receiving area near the first gas chamber in the second free piston is set to be smaller than a pressure receiving area near the second gas chamber.

Abstract: A shock absorber includes: a bottomed cylindrical outer tube that is disposed so as to cover an inner case, and that is formed of a resin and is closed at one end by a closing part; a joint member that is embedded by insert molding in an opening end of the outer tube; and a coupling member that is coupled to the joint member.

Abstract: In a shock absorber, an outer case made of resin is disposed so as to cover an inner case made of metal, and the outer case forms a reservoir chamber for storing the hydraulic fluid between the outer case and the inner case. The outer case is supported by the inner case via protrusions, which are formed on either one of the outer peripheral surface of the inner case and the inner peripheral surface of the outer case so as to protrude toward and abut the other one of the outer peripheral surface of the inner case and the inner peripheral surface of the outer case.
