Abstract
A driving force transmission device for a vehicle has a homokinetic joint having an outer ring and a clutch device having an outer ring coupled to the outer ring of the homokinetic joint. An input shaft is rotatably inserted in the outer rings. A cage is rotatably mounted between opposed surfaces of the outer rings and the input shaft. The cage has pockets. Engaging elements are mounted in the pockets. They are adapted to engage the opposed surfaces when the input shaft and the cage rotate relative to each other either clockwise or counterclockwise. Elastic members are mounted in the pockets to keep the engaging elements in a not-engaged position. The cage and the input shaft are coupled together with a gap extending in the direction of rotation formed therebetween so as to be rotatable together. A differential member are mounted on the cage or the input shaft to produce a difference in rotation therebetween.
