Abstract
In an embodiment, a sliding component includes a pair of sliding parts (a stationary-side seal ringand a rotating-side seal ring) that relatively slide on each other and each have a sliding face S formed radially for sealing sealed fluid from leaking. The sliding face S of at least one sliding part is provided with dynamic pressure generation groovesspaced in a non-communicating manner from the sealed-fluid side and the leakage side by lands R of both sliding faces, and is provided with fluid introduction holesbetween leakage-side endsof the groovesand the leakage side, for communicating the groovesand the leakage side. Each fluid introduction holesis configured such that a dynamic-pressure-generation-groove-side openingopen to a corresponding one of the groovesis axially displaced from a leakage-side openingopen to the leakage side.
