Patent attributes
There is provided a sliding component that supplies a sealed fluid to a leakage side in a gap between sliding surfaces to exhibit high lubricity and has a small leakage of the sealed fluid. A sliding component has an annular shape and is disposed in a place where relative rotation is performed in a rotary machine. The sliding component includes a plurality of dynamic pressure generating mechanisms provided in a sliding surface of the sliding component. Each of the dynamic pressure generating mechanisms includes a deep groove portion that communicates with a leakage side, and a shallow groove portion that communicates with the deep groove portion and extends from the deep groove portion in a circumferential direction. An end portion in an extending direction of the shallow groove portion is formed into a tapered shape in a plan view.
