Abstract
A tapered roller bearing includes an inner ring, an outer ring, a plurality of tapered rollers, and an annular cage that holds the tapered rollers. The cage has a small annular portion positioned toward the axially first side with respect to the tapered rollers, a large annular portion positioned toward the axially second side with respect to the tapered rollers, and a plurality of cage bars that couples the small annular portion and the large annular portion together, and the cage is enabled to come into contact with an inner peripheral surface of the outer ring so that the contact allows the cage to be positioned in a radial direction. The small annular portion is provided with introduction channels through which lubricant is enabled to be introduced from a bearing exterior on the axially first side into an annular space formed between the inner and outer rings.
