ABSTRACT:
A torque transmission device has an outer ring and an input shaft rotatably mounted in the outer ring. The outer ring and the input shaft are formed with engaging surfaces so as to be opposite to each other. A cage is rotatably mounted between the engaging surfaces and provided with pockets. The engaging elements are mounted in the pockets and adapted to engage the engaging surfaces when the input shaft and the cage rotate either in a normal or reverse direction relative to each other. Elastic members are mounted in the pockets to hold the engaging elements in a position where they are not engaged. A control shaft is mounted coaxially and rotatably with respect to the input shaft. The cage and the input shaft are coupled together through the control shaft so that a turning torque can be transmitted therebtween. A gap is provided in the direction of rotation at a coupling portion between the input shaft and the control shaft. A differential unit is provided to create a difference in speed between the input shaft and the control shaft.
