PROBLEM TO BE SOLVED: To provide a control cylinder capable of rather easily and smoothly moving a piston assembly. SOLUTION: The piston 74 of the piston assembly 72 moving in a housing 70 is elastically supported by a piston support body 75. The piston support body 75 comprises a case 140 and a rubber member 132, and the rubber member 132 is interposed between the inner peripheral surface 140 of the piston 74 and the outer peripheral surface of a connection shaft 76. Accordingly, even if the relative position of the piston 74 to the inner peripheral surface 96 of the housing in the radial direction is displaced from the relative position thereof in the axial direction, the piston 74 can be displaced radially relative to the inner peripheral surface 96 thereof. Therefore, the displacement can be reduced. As a result, the control cylinder 10 with a rather small sliding resistance between the piston 74 and the housing 96 can be provided.
