摘要: A thrust roller bearing includes a plurality of rollers, a retainer, an annular first track ring having a track surface, an outer periphery flange part, and a first claw part, and an annular second track ring having a track surface, an inner periphery flange part, and a second claw part. Bearing internal gaps to allow the eccentric rotation of the first track ring and the second track ring are provided between the outer periphery flange part and an outer edge part of the retainer, and between the inner periphery flange part and an inner edge part of the retainer. In addition, at least one of the first and second claw parts is a projection part formed by a bending process. Furthermore, an edge part of the retainer opposed to the projection part has a first slope part formed at a corner part on the side opposed to the track surface, and a second slope part having a radial length relatively shorter than that of the first slope part, and formed at a corner part on the opposite side in a thickness direction.

摘要: A needle roller and cage assembly include a cage having a width larger than a diameter thereof. Pillar sections of the cage each include roller retaining portions on radially inner and outer sides with respect to a roller pitch circle diameter and an oblique portion through which the roller retaining portions are continuous with each other. The oblique portion includes a first relief portion formed therein, for avoiding interference with a needle roller. The adjacent pillar sections form a pocket having a rectangular shape therebetween. The pocket includes a second relief portion in each of four corners thereof. The second relief portion extends in the axial direction of the cage from a position at which a short side of the pocket is elongated in a circumferential direction of the cage to an outer end of the roller retaining portion on the radially outer side.
