Abstract
A rotation transmitting device has an input shaft coupled to the transmission of the engine of a four-wheel drive vehicle and an output shaft coupled to the rear wheel differential. The input and output shafts are mounted rotatably and concentrically relative to each other. An outer ring is rotatably mounted around the input shaft and a cage is rotatably mounted between the opposed surfaces of the input shaft and the outer rink and formed with a plurality of pockets. Engaging elements are mounted in the pockets and adapted to engage the opposed surfaces when the cage and the input shaft rotate relative to each other. Resilient members are mounted in the pockets to keep the engaging elements out of engagement with the opposed surfaces. The cage and the output shaft are coupled to the input shaft with a gap left therebetween in the direction of rotation so as to be rotatable to,ether. The input and output shafts are kept in a neutral position of the above gap by a retaining member. The outer ring is provided with a connecting portion through which the outer ring is connected with a drive shaft coupled to the front wheel differential.
