Claims

[Scope of utility model registration request]

(1) In the backing that is inserted into the annular groove cut on the opposing circumferential surface of either the cylinder member or the piston member that are fitted to each other, a synthetic resin material, a hard rubber material, etc. that is in close contact with the other member It has a seal ring made of an elastic material or a soft metal, and a tightening ring made of a rubber-like elastic material that fits into the seal ring and applies close pressure, and the close side peripheral surface of the seal ring is axially It is formed into a combination of a conical surface and a cylindrical surface that gradually becomes thicker as possible from one end toward the center, or a combination of two conical surfaces that are intertwined and gradually become thicker as possible from both ends in the axial direction toward the center. , further comprising: forming an obtuse angle between both surfaces of the backing.

(2) In the pressing, the cross-sectional shape of the ring can be changed to circular, X-shaped, or U-shaped.
The paramole according to claim 1 of the utility model registration claim, characterized in that it is formed into a shape or a rectangular shape.
