Abstract
Needle bearings are interposed between roller supporting members and collars of thrust bearings for traction rollers, respectively. Each thrust bearing is supported on a pivotal portion of a shaft which is in turn supported at its pivot base portion on each roller support member. Each needle bearing includes a plurality of first needles arranged in a circular array concentric with the pivot base portion of each shaft and a plurality of second needles arranged in a part-circular array along the outer periphery of the first needles.
