<p>Provided is a seal ring that can suppress the blowing out of a fluid to be sealed while reducing sliding torque. The seal ring (100), which is firmly attached to a side wall surface on the low-pressure side (L) of an annular groove (410), and which slides relative to an inner peripheral surface of a shaft hole through which a shaft (400) is inserted in a housing (500), is characterized in comprising a concave part (120) provided to the widthwise center in the outer peripheral surface and extending in the circumferential direction, a first convex part (130) which is provided to the low-pressure side (L) via the concave part (120) and which slides relative to the inner peripheral surface of the shaft hole, and a second convex part (140) which is provided to the high-pressure side (H) via the concave part (120) and which protrudes by a lesser amount than the first convex part (130).</p> |
