Abstract
Power rollers 18c are comprised by an inner roller 93 making frictional contact between the input and output disks 18a, 20a and an outer roller 94 supporting a contact load input from the input and output disks 18a, 20a to the inner roller 93 through a ball bearing 92. An inner radial hole 93a is provided on the inner roller 93 to support a pivot shaft 15. The inner radial hole 93a opens near the outer roller and is covered by a bottom part 93b 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.
