ABSTRACT:
A rotation transmitting device having an outer ring formed with a bore, a holder fixedly mounted in the bore and rolling elements mounted in the holder so as to be rollable as the outer ring rotates. A pair of input shafts are provided coaxially with an axis of rotation of the outer ring so as to sandwich the rolling elements from both sides thereof. Output shafts are rotatably mounted in the bore at both sides of the input shafts. Cages are rotatably mounted between the output shafts and the outer ring and formed with pockets. Engaging elements are mounted in the pockets and adapted to be engageable between opposite surfaces of the outer ring and the output shafts with relative rotation between the cages and the output shafts in either direction. Elastic members are mounted in the pockets to keep the engaging elements in a position where they are not engaged. The cages and the output shafts are coupled to the respective input shafts so that a driving force can be transmitted between the input shafts and the output shafts. The input shafts and the output shafts are coupled together with gaps formed therebetween in the direction of rotation.
