Abstract
A tapered roller bearing includes an inner ring, an outer ring, a plurality of tapered rollers, and an annular cage. The annular cage includes a small-diameter annular portion, a large-diameter annular portion, and a plurality of cage bars that couple the small-diameter annular portion and the large-diameter annular portion together. The cage bar has a first facing surface that faces the outer peripheral surface of the tapered roller that is housed. The first facing surface includes a large-diameter-side facing surface, a small-diameter-side facing surface arranged farther away from the outer peripheral surface of the tapered roller than the large-diameter-side facing surface, and an intermediate facing surface inclined gradually away from the outer peripheral surface of the tapered roller with increasing distance from the large-diameter-side facing surface to the small-diameter-side facing surface.
