Claims

[Scope of utility model registration request]

The journal is rotatably supported on a half-split bearing,
In the lubrication structure of the half-split bearing, a bearing oil groove is formed on the sliding surface of the half-split bearing with the journal, and lubricating oil is supplied to the bearing oil groove through a bearing oil hole drilled in the bearing. A half-split type bearing characterized in that a bearing oil groove is partially formed in the circumferential direction from the mating surfaces of both ends of the bearing, which is a non-load area, to the clutch relief by removing the bearing oil groove from the upper and lower parts of the bearing, which are the load area of the bearing. lubrication structure.
