Abstract
In an embodiment, in a slide component, dynamic pressure generation grooves 10 are provided on a sealing face of at least one of a pair of slide parts 4, 7 so 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 sections 11 is provided at positions on the sealing face IS between the dynamic pressure generation grooves 10 and 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.
