摘要： There are provided sliding components that allow sliding surfaces to smoothly slide against each other regardless of whether a relative rotation direction is a forward rotation or a reverse rotation. The sliding components and include: a pair of sliding surfaces and disposed to face each other at a location where a relative rotation takes place when a rotating machine is driven. The sliding surface is provided with a first dynamic pressure generating groove communicating with a radially outer-side space and extending in one circumferential direction, a second dynamic pressure generating groove extending in the opposed circumferential direction, and a conduit groove communicating with the space. The conduit groove includes an annular groove and a communication groove communicating between the annular groove and the space. The second dynamic pressure generating groove is disposed closer to the space than the annular groove, and communicates with the annular groove.

摘要： Provided is a sliding component capable of maintaining high lubricity over a long period of time by efficiently using a liquid supplied between sliding surfaces. In a pair of sliding components disposed at a relatively rotating position to face each other when a rotating machine is driven, a sliding surface of the sliding component is formed on an outer peripheral edge portion and includes an opening portion extending in a circumferential direction and a fluid supply groove communicating with the opening portion and opening to a peripheral edge of the sliding surface on the side of the opening portion.
