PROBLEM TO BE SOLVED: To provide a tapered roller bearing improved in assemblability.SOLUTION: This tapered roller bearing includes: an inner ring 10; an outer ring 20; a plurality of tapered rollers 30; and a retainer 40. The inner ring 10 is formed with a large flange 12 which guides a large end surface 32 of the plurality of tapered rollers 30, in a large-diameter side end part of an inner ring raceway surface 11, and is formed with a small flange 15 which guides a small end surface 33 of the plurality of tapered rollers 30, in a small-diameter side end part of the inner ring raceway surface 11. A small-diameter side end part of a pocket 43 of the retainer 40 is formed with a contact part 47, which can be brought into contact with a part positioning on the inner diameter side of the retainer 40 than the position of the center of gravity of the tapered roller 30 in a small end surface 33 of the tapered roller 30. |
