Abstract
A recess is provided in the large-diameter annular portion of a cage of a tapered roller bearing. A first clearance between the large-diameter annular portion and the outer ring is smaller than a second clearance between the small-diameter annular portion and the outer ring. The large-diameter annular portion includes, in its outer periphery, a tilted surface whose diameter increases toward the other side in an axial direction. The tilted surface faces an inner peripheral surface of the outer ring.
