Abstract:
Between an inner race and an outer race, a plurality of thrust rollers supporting the inner race and the outer race capable of relative rotation are provided. A thrust cage for retaining each thrust roller capable of rolling is composed of a plurality of cage separate bodies separated and arranged in a roller accommodating space. The cage separate body has two projecting portions having a semicircular cross-sectional shape provided on an outer wall surface of an outside connecting portion spaced apart from each other in a peripheral direction of the outer race. With relative rotation between the inner race and the outer race, when each cage separate body is displaced toward an inner peripheral surface side of the outer race, a top portion of each projecting portion is brought into contact with the inner peripheral surface of the outer race.
