Abstract

A thrust race of a thrust roller bearing has a race portion and a cylindrical portion extending from the race portion in an axial direction. At a plurality of locations along a circumferential direction on the cylindrical portion, cutout portions are formed such that each of the cutout portions is recessed in the axial direction from a distal edge of the cylindrical portion toward the race portion. A protrusion is provided at a portion closer to the race portion from a bottom edge of each of the cutout portions such that the protrusion protrudes in a radial direction from the cylindrical portion toward a side away from the race portion. The protrusion serves as a race-retaining locking portion to prevent a race from moving out from a mating member on which the race is mounted.
