description	An object of the present invention to provide a tapered roller bearing in which a flange portion is formed at a large-diameter end of an outer ring track surface of an outer ring, capable of providing high moment stiffness and long life without extremely decreasing its pure axial load capacity. The tapered roller bearing comprising: an outer ring 12 having an outer ring track surface 12a on its inner circumferential surface; an inner ring 13 having an inner ring track surface 13a on its outer circumferential surface; a plurality of tapered rollers 14 rotatably disposed between the outer ring track surface 12a and the inner ring track surface 13a; and a retainer 15 having a plurality of pockets for retaining the plurality of tapered rollers 14 at a predetermined interval; the outer ring track surface 12a of the outer ring 12 having a small-diameter end and a large-diameter end, the inner ring track surface 13a of the inner ring 13 having a small-diameter end and a large-diameter end, and, of these four ends, a flange portion 12b that protrudes radially inwardly is formed at the large-diameter end of the outer ring track surface 12a of the outer ring 12; wherein the tapered roller bearing has a contact angle greater than 35° and a roller angle not greater than 3.5°.
