Abstract:
This tapered roller bearing 10 comprises an outer ring 11, an inner ring 12, a plurality of tapered rollers 13, and an annular retainer 14. The retainer 14 has a small diameter annular section 15, a large diameter annular section 16, and a plurality of columns 17 that link the small diameter annular section 15 and the large diameter annular section 16. The inner ring 12 has a large flange section 24 that is in sliding contact with a large end surface 38. A recessed section 20 that opens toward the large end surface 38 is provided to the large diameter annular section 16. A first gap between the large diameter annular section 16 and the outer ring 11 is smaller than a second gap between the small diameter annular section 15 and the outer ring 11. The large diameter annular section 16 has, on the outer circumference, a sloped surface 31 the diameter of which widens toward the other side in the axial direction thereof. The sloped surface 31 has a facing surface section that is located further toward one side in the axial direction than a virtual plane that follows a side surface 81 on the other side in the axial direction of the outer ring 11, and faces the inner circumferential surface of the outer ring 11.
