Abstract
A sliding component provides both functions of leakage prevention and lubrication in accordance with environments such as the type, temperature, and pressure of a sealed fluid and the sliding speed of a sliding face. Dimplesare provided in one of the sliding faces of a pair of sliding parts that slide relative to each other. Each of the dimpleshas an upstream cavitation formation regiondisposed close to the low-pressure fluid side and a downstream positive pressure generation regiondisposed close to the high-pressure fluid side. The positive pressure generation regionhas a downstream distal end at which a positive pressure relief grooveconnecting the positive pressure generation regionand the high-pressure fluid side is provided, thereby being configured to control the ratio between the size of the cavitation formation regionand the size of the positive pressure generation region
