Tapered roller bearing

A tapered roller bearing comprising:

• an outer ring including an outer ring raceway surface whose diameter increases from one side in an axial direction toward another side in the axial direction;
• an inner ring including an inner ring raceway surface whose diameter increases from the one side in the axial direction toward the other side in the axial direction;
• a plurality of tapered rollers each including a large end face on the other side in the axial direction;
• and
• an annular cage that holds the plurality of tapered rollers, wherein
• the cage includes
• a small-diameter annular portion located on the one side in the axial direction of the tapered rollers,
• a large-diameter annular portion located on the other side in the axial direction of the tapered rollers, and
• a plurality of bars connecting the small-diameter annular portion and the large-diameter annular portion,
• the inner ring includes a large rib that slidingly contacts the large end face,
• a recess that is open toward the large end face is provided in the large-diameter annular portion,
• 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 an outer periphery of the large-diameter annular portion, a tilted surface whose diameter increases toward the other side in the axial direction,
• the tilted surface includes an opposing surface portion that is located on the one side in the axial direction with respect to an imaginary plane extending along a side surface on the other side in the axial direction of the outer ring, and that faces an inner peripheral surface of the outer ring,
• the bar includes, on a radially outer side of the bar,
• a first outer surface that increases a distance to the inner peripheral surface of the outer ring toward the other side in the axial direction,
• a second outer surface that is continuous with the first outer surface and continuous with an outer peripheral surface of the small-diameter annular portion, and
• a wall surface extending from an end on the other side in the axial direction of the first outer surface toward the outer ring,
• the bar includes, on the radially outer side of the bar,
• an extended surface that is continuous with the wall surface via a bent portion and continuous with the tilted surface of the large-diameter annular portion without via a bent portion, and
• a distance from the extended surface of the bar and the tilted surface of the large-diameter annular portion to the inner peripheral surface of the outer ring is smaller than a distance from the second outer surface to the inner peripheral surface of the outer ring.
