ABSTRACT:
A rotation transmission device which can quickly change the direction of rotation includes an inner ring having cam surfaces on its outer periphery, an outer ring having a cylindrical surface on its inner periphery, and pairs of circumferentially opposed rollers, the rollers of each pair being disposed between one of the cam surfaces and the cylindrical surface to be circumferentially opposed to each other. A roller separation spring is disposed between the rollers of each pair of rollers to bias the rollers away from each other so that the rollers are wedged between the cam surface and the cylindrical surface. The rollers are retained by a roller retainer which can change the distance between the rollers of each pair of rollers. By reducing the distance between the rollers of each pair of rollers with the roller retainer, the rollers can be disengaged from the cam surfaces and the cylindrical surface.
