Abstract
In an embodiment, in a sliding component, a sliding face of a stationary-side seal ringhas a fluid circulation groovecommunicating with a high-pressure fluid side via an entrance portionand an exit portion. A rotating-side seal ringhas a larger outer diameter and a smaller inner diameter than the seal ring. A grooveinto which a claw is loosely fitted is provided on an outer periphery of the seal ring. A width of the grooveis smaller than a distance between the portionand thein 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 grooveand an inner diameterof the sliding face; WSR is a face width of the sliding face).
