Provided is a seal ring that can both reduce friction loss and control oil leaks. A seal ring comprises an outer circumferential face, an inner circumferential face that is opposite to the outer circumferential face, a side face that joins the outer circumferential face and the inner circumferential face, and a plurality of pockets that are provided on the side face with spaces therebetween and that are closed on the outer circumferential face side and opened on the inner circumferential face side. Each pocket has a first and second edge and a first and second inclined face. The first edge and second edge are provided on the ends in the circumferential direction, respectively, and are convex beveled faces that extend from the side face and project to the side face with tips having a radius of curvature of no more than 60 mm. The first and second inclined faces extend from the first and second edges, respectively, toward the center in the circumferential direction. |
