Abstract
Provided is a seal ring configured so that stable lubrication performance can be provided across a wide range of rotation speed. A seal ring for sealing a clearance between a rotary shaft and a housing includes inclined grooves formed at a sliding surface so as to be arranged in a circumferential direction, the inclined grooves being open on an outer diameter side of the seal ring to generate a drawing pressure. The seal ring further includes supply grooves being open on a sealed fluid side of the seal ring and extending in a radially outward direction toward inner diameter sides of the inclined grooves.
