Patent ID: 7806246

Claim:
A lubricating structure of a one-way clutch comprising: an inner race; an outer race; a plurality of rollers disposed between said inner race and said outer race, each roller of said plurality of rollers having a respective rotational axis; and a lubricating oil passage, formed in said inner race in a substantially straight line, including a first end opened in a rolling surface on which said rollers roll and a second end that opens in a side wall of the inner race; wherein said lubricating oil passage is tilted relative to a perpendicular line orthogonal to a rotational axis of said inner race and tilted relative to the respective rotational axes of said plurality of rollers as viewed from an outer circumferential side of said inner race, such that a centerline of the lubricating oil passage intersects a plane containing both the perpendicular line orthogonal to the rotational axis of the inner race and the rotational axis of the inner race at a single point; and wherein a groove-shaped oil receiver facing an inner-diameter side of said inner race is provided in a vicinity of the second end of said lubricating oil passage.
