Is mounted on a bearing base 7 having an oil tank 5 inside. The rotating shaft 1 has two oil rings 9,
11 is loosely fitted and hung. The lower ends of these oil rings 9 and 11 are immersed in the lubricating oil 13 of the oil tank 5. These oil rings 9 and 11 are
When the rotating shaft 1 rotates, the rotating shaft 1 follows the rotating shaft 1 due to frictional force and rotates.

It becomes possible. Also, by providing the inner ring with a plurality of small holes communicating the inside of the concave groove and the rotating shaft side, lubricating oil that has entered the gap between the inner ring and the outer ring can easily accumulate in the concave groove,
Since the lubricating oil in the concave groove is pushed out toward the rotating shaft side at the position closest to the rotating shaft (the position where the inner ring or the outer ring fits most in the concave groove), the so-called oil holding of the lubricating oil is improved and sufficient An appropriate amount of lubricating oil can be efficiently supplied to the rotating shaft.
