摘要： A seal ring (20) fitted into a ring groove (4) provided in the outer peripheral surface of a shaft (2) has side surfaces (21a,b) and an inner circumferential surface which receive hydraulic pressure supplied to the ring groove (4). The side surfaces (21a,b) of the seal ring (2) are tapered surfaces so that the width of the seal ring (2) at its inner circumferential surface is smaller than the width of the seal ring (20) at an outer circumferential surface (22) thereof. The outer circumferential surface (22) of the seal ring (20) is arcuate in cross section. Hydraulic pressure which acts upon one side surface (21b) of the seal ring causes the other side surface (21a) of the seal ring (20) to come into sliding contact with the side wall surface (41) of the ring groove (4). As a result, loss torque due to sliding contact is reduced. The tapered surfaces (21a) of the seal ring (20) contact the edge of the side wall surface (41) of the ring groove (4) at all times so that there is no leakage of oil.
