Abstract
The present invention provides a power transmission mechanism characterized in that two-directional rotations of a driving shaft can be transmitted to a driven-side shaft, it shows a high degree of freedom in arrangement even when it is applied to a driving force transmission system, the driving force of a driving-side input shaft can be transmitted to a driven-side ring via a roller in each of opposite directions, and when the rotational speed of the driven-side ring is higher than that of the driving-side input shaft, no driving force is transmitted from the driving-side input shaft to the driven-side ring in either of the opposite directions.
