PROBLEM TO BE SOLVED: To prevent failure such as seizure and the like from happening between a roller of a rolling bearing and a flange part.SOLUTION: An inner ring 10 has: a cylindrical bearing ring body part 11 having a raceway surface 12 on which a plurality of rollers 30 roll; and an annular flange part 13 provided protruding radially outward from an axial direction end part of the bearing ring body part 11, and receiving a load from the roller 30 by coming into contact with an axial direction end surface 31 of the roller 30. The flange part 13 has: an annular fixing part 41 which is integral with the bearing ring body part 11 and which protrudes radially outward from the bearing ring body part 11; and an annular rotation part 42 provided between the roller 30 and the fixing part 41. The rotation part 42 has a contact surface 43 coming into contact with the axial direction end surface 31 of the roller 30, and it becomes rotatable as slippage occurs between itself and the fixing part 41. |
