A seal element which is disposed on the outer peripheral surface of the piston to obtain sealing between the piston and cylinder comprises a ring portion affixed to the piston and the flange portion extending radially outwardly from the end portion of the ring portion. A cut out space is formed on the inner surface of the flange portion which connects with the ring portion.
