A cylinder comprising a cylinder having cylinder holes and at least one guide hole installed in parallel to each other, a piston that reciprocates between the cylinder hole and the guide hole, a guide rod, and a plate having the piston rod. A fluid pressure cylinder that supplies and discharges pressurized fluid from a port provided in the piston to a pair of pressure chambers separated by a piston to drive the piston and plate together, and one of the guide hole and the guide rod is a cushion ring. The other of these includes an axial recess into which the cushion ring is loosely fitted, and a cushion gasket that is attached to the inner peripheral surface of the recess and slides into contact with the outer peripheral surface of the cushion ring near the end of the stroke of the piston. A fluid pressure cylinder having a cushion mechanism, wherein the port and the guide hole are in communication with each other through a main flow path and a bypass flow path having a flow rate regulating valve. 2. A fluid pressure cylinder having a cushion mechanism according to claim 1, wherein a seal ring is attached to the inner circumferential surface of the recess, and a check valve is provided in the main flow path to allow fluid to flow only into the recess.
