摘要:
In an embodiment, a sliding component includes a pair of sliding parts (a stationary-side seal ring 7 and a rotating-side seal ring 4) 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 grooves 10 spaced 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 holes 11 between leakage-side ends 10a of the grooves 10 and the leakage side, for communicating the grooves 10 and the leakage side. Each fluid introduction holes 11 is configured such that a dynamic-pressure-generation-groove-side opening 11a open to a corresponding one of the grooves 10 is axially displaced from a leakage-side opening 11b open to the leakage side.
