A cylinder device (C1) includes a recess (2a) provided on either one of the piston (2) and the cylinder (1), the recess (2a) facing the other one of the piston (2) and the cylinder (1); an extension-side discharge passage (6) configured to permit only a flow of liquid from the extension-side chamber (R1) toward the recess (2a); a compression-side discharge passage (7) configured to permit only a flow of liquid from the compression-side chamber (R2) toward the recess (2a); a tank-side discharge passage (8) configured to allow the extension-side discharge passage (6) and the compression-side discharge passage (7) to communicate with the tank (T) through the recess (2a); an extension-side damping force generation passage (9) configured to apply a resistance to a flow of liquid passing therethrough so as to exert a damping force during extension; and a compression-side damping force generation passage (10) configured to apply a resistance to a flow of liquid passing therethrough so as to exert a damping force during contraction.
