Claims

[Scope of Claim for Utility Model Registration] A cage that rotatably holds a plurality of rollers is rotatable relative to a race, and a locking portion provided on the inner diameter or outer diameter of the race to prevent the cage from coming off. In a thrust roller bearing configured to be mounted in an axially non-separable state by A thrust roller bearing characterized in that a predetermined gap is formed in the axial direction between the locking portion and a side surface of the retainer on the side of the locking portion.
