Claims

[Scope of Claim for Utility Model Registration] (1) A bearing ring and an annular ring that fits inside the bearing ring, and pocket holes for storing and holding a plurality of needles are provided on the circumferential surface of the bearing ring at equal intervals in the circumferential direction. In a thrust needle bearing with an integrated raceway and a retainer, staking claws are provided at the ends of the outer peripheral wall or the inner peripheral wall of the raceway that protrude toward the retainer fitting side, and are made of synthetic resin. A thrust needle bearing characterized in that a notch-like recess into which a staking claw fits and passes is provided on the outer peripheral edge or inner peripheral edge of the retainer. (2) The thrust needle bearing according to claim 1, wherein a chamfered portion is provided on the outer peripheral edge of the retainer on the surface facing the staking claws.
