Abstract
In an exemplary embodiment, a sliding member includes sliding faces S configured to slide in relation to one another, at least one sliding faceof the sliding faces being provided with a plurality of dimpleshaving multi-sided shapes whose edges are formed without interruption. A pair of the edges A-B, A-Cof each of the multi-sided dimples, extending radially on opposite sides of a radial axis R of the sliding member, are sloped to become farther apart as they extend toward a high-pressure fluid side, and an edge B-C, which connects end points B, Con the high-pressure fluid side of the pair of the edges, is formed such that its length is not greater than the lengths of the pair of the edges A-B, A-C. The sliding member can reduce friction between the sliding faces and improve sealing performance regardless of the direction of rotation.
