Abstract
A sealing device includes a stationary member, an orbiting member, a tip end surface of which slides on an inner face of the stationary member, and a sealing member to be fitted into a sealing groove engraved on the tip end surface. A sliding contact surface of the sealing member is pressed onto an inner surface of the stationary member with a predetermined force to slide on the inner surface in order that fluid sealing is secured between the sliding contact surface of the sealing member and the inner surface of the stationary member. The sealing member is divided into two parts of an upper ring and a lower ring, with the upper ring contacting the sliding contact surface and the lower ring facing a bottom surface of the sealing groove.
