Abstract
Power rollers are comprised by an inner roller making frictional contact between the input and output disks and an outer roller supporting a contact load input from the input and output disks to the inner roller through a ball bearing . An inner radial hole is provided on the inner roller to support a pivot shaft . The inner radial hole opens near the outer roller and is covered by a bottom part on a side opposite to the outer roller. In this manner, compression deformation of the inner roller is suppressed when a load is applied to the inner roller. Thus smooth rotational motion of the power roller is maintained and component durability can be increased.
