Abstract
In an embodiment, in a slide component, dynamic pressure generation groovesare provided on a sealing face of at least one of a pair of slide partsso as to be isolated with no communication from the sealed fluid side and the leakage side by land portions R of both the sealing faces, and a plurality of independently-formed minute recessed sectionsis provided at positions on the sealing face IS between the dynamic pressure generation groovesand the leakage side, the positions being separated in the radial direction from the dynamic pressure generation grooves. The slide component can make the sealing faces fluid-lubricant and low frictional and prevent leakage of a sealed fluid and incoming of dust to the sealing faces at the time of normal operation.
