Abstract
In an exemplary embodiment, a sliding component includes a pair of sliding partsandsliding relatively to each other and having sliding faces S formed radially for sealing a liquid or a misty fluid as a sealed fluid against leakage. One sliding part is a stationary-side seal ring, and the other sliding part is a rotating-side seal ring. At least one of the sliding faces S is provided with positive pressure generation mechanismshaving positive pressure generation groovesconfigured to communicate with a circumferential edge of the sliding face S on the sealed-fluid side and not to communicate with a circumferential edge on the leakage side, and discharge groovesdisposed at an angle such that upstream ends are located on the leakage side and downstream ends are located on the sealed-fluid side.
