To prevent abrasion of an end surface on a large flange portion side of an inner race and abrasion of an end surface of a flange portion of a mating member, a tapered roller bearing includes a washer fixed to the end surface on the large flange portion side of the inner race. A dimensional tolerance between the inner race and the washer, which is required when the washer is fixed to the inner race, is increased to reduce processing cost and to facilitate fixation work of the washer to the inner race. The tapered roller bearing includes a washer (5) fixed to an end surface (1d) on a large flange portion (1c) side of an inner race (1), in which an engagement recess portion (1c2) is provided in an outer peripheral surface (1c1) of the large flange portion (1c) of the inner race (1) and a plurality of elastically deformable claw portions (5b) are formed on an outer peripheral edge of the washer (5) and each provided with an engagement protruding portion (5b1) to be engaged with the engagement recess portion (1c2). |
