Abstract
A tapered roller bearing includes an outer race, an inner race, a plurality of tapered rollers, and a cage. A small-diameter end portion of the inner race is formed with a small flange portion for limiting axial movement of the tapered rollers and a cylindrical portion which has a less diameter than the small flange portion and is connected to an axial outer end of the small flange portion. The cage is formed at a small-diameter end portion thereof with a bent portion which is bent inward in a radial direction. A small-diameter end portion of the cage has a bent portion which is faced to an outer surface of the cylindrical portion of the inner race with a predetermined clearance therefrom such that a labyrinth is created between the cage and the inner race.
