SLIDING PARTS

摘要

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.
