Abstract

PURPOSE: To feed lubricating oil to a bearing effectively by a method wherein a spiral groove is cut in the outside peripheral surface of a bearing hold collar on which an oil ring is mounted.
CONSTITUTION: The outside peripheral surface of a bearing hold collar 3 is set equal to or larger than the outside diameter of the inner ring 2A of a rotating bearing 2, and formed with a spiral groove 3S for feeding lubricating oil to the side of the bearing 2. Thus, the lubricating oil raked up by an oil ring 4 is fed to the side of the bearing 2 effectively.
