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.
