Abstract:
To provide a thrust roller bearing reduced in torque.
The thrust roller bearing 21a is provided with an outer ring 22a, an inner ring 22b, a plurality of rollers 31 rolling on an outer ring raceway surface 24a and an inner ring raceway surface 24b, and an annular cage 11a holding the rollers 31. The cage 11a includes protruded curve surfaces 17a and 17b protruded to a rotation axis direction of the cage 11a. The protruded curve surfaces 17a and 17b are brought into contact with the outer ring 22a in the rotation axis direction. A contact area of the cage 11a and the outer ring 22a can be reduced, therefore, and the torque is reduced.
