。 A U-packet that seals between a casing into which fluid pressure is introduced and a sliding member that slides back and forth relative to the casing is inserted into a packing groove formed in one of the pressure cylinder body or the sliding member. In a sealing mechanism in which the lip portion of the U packing is fitted so as to expand toward the pressure side,
A tapered inclined portion whose diameter is reduced toward the pressure side is formed on the outer circumferential wall of the pressure side of the packing groove, and the anti-rip portion side of the U packing is elastically moved toward the pressure side by a spring means. Seal mechanism made by repelling.
