摘要： A seal ring for sealing an annular clearance between two members which are disposed for free rotations relative to each other. At a cut portion which is cut at a portion of the seal ring, there is formed a passage for allowing leakage when the cut end portions engage with each other. This passage is given a sectional shape of square or the like. This passage improves an abrasion resistance.
