  • Patent number: 10655736
    Abstract: In an embodiment, in a sliding component, a sliding face of a stationary-side seal ring 6 has a fluid circulation groove 10 communicating with a high-pressure fluid side via an entrance portion 10a and an exit portion 10b. A rotating-side seal ring 5 has a larger outer diameter and a smaller inner diameter than the seal ring 6. A groove 15 into which a claw is loosely fitted is provided on an outer periphery of the seal ring 5. A width of the groove 15 is smaller than a distance between the portion 10a and the 10b in the circumferential direction. WMR/WSR is set within a range of 0.75<WMR/WSR<1.4 (WMR is a face width between an inner diameter of the groove 15 and an inner diameter 6b of the sliding face; WSR is a face width of the sliding face).
