Abstract
In a tapered roller bearing, a large rib is provided at one end of an inner ring in the axial direction, and projects radially outward. A lubricating oil holding member is integrated with an outer ring, and disposed at a position overlapping the large rib in the radial direction. The lubricating oil holding member includes a tubular portion and an annular portion. An inclined surface is disposed on the outer peripheral surface of the large rib at one end in the axial direction. The distance from the rotational axis of the inner ring to the inclined surface becomes larger from one side in the axial direction toward the other side. An end of the inclined surface is positioned, in the axial direction, between the annular portion and one end of the outer ring in the axial direction.
