Abstract
In a suspension device, a first piston is movable in an axial direction inside of a cylinder, and an inner pipe that extends in the axial direction is provided inside of the cylinder. A first rod is coupled to the first piston and inserted into the inner pipe. A second rod is coupled to the first piston and projects outwardly from the cylinder. A second piston is movable in the axial direction while sealing a space between an outer surface of the inner pipe and an inner surface of the cylinder. A first gas chamber is located between the second piston and a closure to be arranged outside of the inner pipe. A second gas chamber is located inside of the inner pipe. The first rod includes a first inner passage that communicates with the second gas chamber, and the second rod includes a second inner passage that communicates with the first inner passage.
