。The inner periphery of a rubber ring is fitted into an annular groove with a substantially U-shaped cross section that opens toward the center of the cylinder and is provided on the cylinder chamber side end of the inner periphery wall of the head cover or rod cover at the end of the cylinder. In a cushion seal device for a fluid pressure cylinder that reduces the movement speed of a piston by slidingly contacting a cushion collar that is coaxial with and adjacent to the piston, a cylinder chamber is connected to the side wall of the cylinder chamber near the bottom of the annular groove. A through hole is provided for communication, the width is thinner than the width of the annular groove, and a fluid communication path extending in the width direction is provided on the outer periphery of the groove, and an annular notch is provided on at least one of the outer periphery ends. A rubber ring is fitted into the annular groove so as to be slidable in the direction along the cylinder center line so that the notch side faces the cylinder chamber side, thereby forming an annular passage connecting the fluid communication passage and the through hole. Cushion seal device.
