<P>PROBLEM TO BE SOLVED: To provide a seal material that can be used under high-pressure conditions without concurrent use of an auxiliary member such as a back-up ring, and that has little sliding resistance so as to achieve a longer service life of the seal material. <P>SOLUTION: The seal material is mounted in a seal groove formed on a mounting body, and contacts a seal surface of a mating member so as to seal between the mounting body and the mating member. The seal material is provided with: an elastic member that is formed from an elastic material; and a seal member that is formed from a material with lower frictional properties than the elastic member, and is joined to the upper surface of the elastic member. The seal material is configured such that a lip section is formed extending outward and downward on the elastic member, and when the seal material is mounted in the seal groove, the lip section of the elastic member contacts the bottom surface of the seal groove, and the upper surface of the seal member contacts the seal surface. <P>COPYRIGHT: (C)2012,JPO&INPIT |
