    摘要： Provided is a seal ring capable of stably reducing a rotational torque while preventing the leakage of sealed fluid. The seal ring includes: an abutment joint part (110) provided at one portion in a circumferential direction thereof; a plurality of dynamic pressure generation grooves (120) provided at intervals in the circumferential direction on a side of a sliding surface thereof sliding on a lateral wall surface of an annular groove; and foreign matter discharging grooves (130) that are provided between a region in which the plurality of dynamic pressure generation grooves (120) is arranged and the abutment joint part (110) in the circumferential direction on the side of the sliding surface sliding on the lateral wall surface, and that are capable of catching foreign matter intruding from the abutment joint part (110) and discharging the caught foreign matter to an outside of a sliding part between the seal ring and the lateral wall surface.

    摘要： Provided is a seal ring capable of stably reducing a rotational torque while preventing the leakage of sealed fluid. The seal ring includes, on a side of a sliding surface thereof, a groove part (120) having a first groove (121) extending in a circumferential direction thereof and a second groove (122) extending from a central position of the first groove (121) in the circumferential direction to an inner peripheral surface and guiding sealed fluid into the first groove (121), the first groove (121) having dynamic pressure generation grooves (121a) configured to have a groove bottom made shallower at an end thereof in the circumferential direction than at a center thereof in the circumferential direction, and a foreign matter catching groove (121b) that has a groove bottom deeper than the groove bottoms of the dynamic pressure generation grooves (121a) and is capable of catching foreign matter, and the first groove (121) being provided at a position that falls within a sliding region in which the seal ring slides on the lateral wall surface.
