Abstract

There is provided a seal ring capable of maintaining parallelism between sliding surfaces. A seal ring 3 includes a sliding surface 3a that rotates and slides relative to one of a shaft 1 and a housing 2 through which the shaft 1 is inserted; and an installation surface 3b that intersects the sliding surface 3a and that is installed on remaining one of the shaft 1 and the housing 2. The seal ring 3 partitions one space H, which is located on a side opposite to a side on which the sliding surface 3a intersects the installation surface 3b, off from another space L disposed on the side on which the sliding surface 3a intersects the installation surface 3b. The sliding surface 3a includes a dynamic pressure generation mechanism 36 communicating with the one space H and including a dynamic pressure generation portion 39b, and a fluid recovery mechanism 37 that is disposed closer to the one space H side than the dynamic pressure generation portion 39b to communicate with a relative rotation downstream side of the dynamic pressure generation mechanism 36, and that does not communicate with the one space H side.
