Abstract: By randomly arranging dimples provided on a sealing face, a sliding characteristic is improved in a wide range of a bearing characteristic number on the sealing face. A pair of sliding parts in which a plurality of dimples is arranged on at least one of sealing faces that relatively slide on each other is characterized in that each of the plurality of dimples is provided independently from the other dimples, and arranged in such a manner that the plurality of dimples having different opening diameters is randomly distributed.

Abstract: A fluid is actively taken into sealing faces and discharged from the sealing faces to prevent concentration of sediment causative substances on the sealing faces and prevent generation of sediment while preventing leakage of the fluid taken into the sealing faces to a low pressure fluid side. A fluid circulation groove includes an inlet side section where the fluid comes in from a high pressure fluid side and an outlet side section where the fluid goes out to the high pressure fluid side in one of sealing faces of a pair of sliding parts that slide on each other. The fluid circulation groove is isolated from the low pressure fluid side by a land section. Groove width of the outlet side section of the fluid circulation groove is gradually expended toward an outlet end.

Abstract: A pair of sliding parts include sliding faces that include a fluid circulation groove including an inlet section where a fluid comes in from a high pressure fluid side, an outlet section where the fluid goes out to the high pressure fluid side. A communication section provides communication between the inlet section and the outlet section in at least one of sealing faces of a pair of sliding parts that slide on each other. The fluid circulation groove is isolated from a low pressure fluid side by a land section R. A section of a bottom wall of the fluid circulation groove is formed in a round bottom shape.
