クッションシール装置。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 cylinder end cover or rod cover. In a cushion seal device for a fluid pressure cylinder that reduces the movement speed of a piston by slidingly contacting a cushion collar concentric with and adjacent to the piston, the side wall on the side of the inner chamber near the bottom of the annular groove A through hole communicating with the cylinder chamber is provided in the annular groove, and a rubber ring is fitted into the annular groove so as to be slidable in the direction along the cylinder center line. What is claimed is: 1. A cushion seal device characterized in that the cushion seal device is symmetrical in plane with respect to the cushion seal device, and a fluid communication path communicating with a through hole is provided on the outer periphery of the cushion seal device.
