Patent attributes
A sliding component has a plurality of dimples provided independently in a circumferential direction on one sealing face of a pair of sliding components relatively sliding to each other. A cavitation formation region on an upstream side of each dimple is disposed closer to a low-pressure fluid side and a positive pressure generation region on a downstream side of each dimple is disposed closer to a high-pressure fluid side, and an edge on the low-pressure fluid side of the positive pressure generation region is formed into a tapered shape inclined with respect to the rotating direction of the other sealing face toward the high-pressure fluid side from the low-pressure fluid side and is smoothly connected to an edge on the low-pressure fluid side of the cavitation formation region.
