Abstract

The present invention provides a seal ring capable of stably leaking a seal fluid from an inner peripheral surface side. It is characterized in that, in the sealing ring, the fitting part of the first convex part (10R1) fitted into the second concave part (10L2) and the fitting part of the second convex part (10R2) fitted into the first concave part (10L2) are A leakage passage (S3) between the sides connecting the first gap (S1) and the second gap (S2) is provided, at the end on the inner peripheral side of the cut end (10R) on one side and inside the cut end on the other side. In a state where the ends on the peripheral side are in contact, a passage is formed that communicates from the inner peripheral surface side to the leakage passage between the side surfaces.

Description

technical field [0001] The invention relates to a sealing ring. Background technique [0002] Sealing rings for sealing the annular gap between the shaft and the shaft hole are known and are mounted in an annular groove on the shaft inserted into the shaft hole of the bushing, with the non-sealed fluid side of the annular groove The side wall surface of the shaft is in slidable contact with the inner peripheral surface of the shaft hole. [0003] This seal ring is suitable for various devices, but for seal rings used in high-pressure, high-rotational environments, the problem is how to prevent deterioration due to wear. Especially in recent years, seal rings used in ATs and CVTs for motor vehicles have to adapt to higher rotational speeds as the performance of ATs and CVTs has improved. [0004] As a technique for suppressing wear of seal rings, it is known that oil as a seal fluid is intentionally leaked to the sliding surface side to form an oil film on the sliding surfa...
