ABSTRACT:
An overrunning clutch that can absorb the impact torque, and accurately and easily conveys the maximum torque. A clutch outer tubular portion and inner tubular portion are separately fixed on an internal gear and a center case of an epicycle gear reduction mechanism. A wedge-shaped groove is formed on one of an inner circumference of the outer tubular portion and an outer circumference of the inner tubular portion to accomodate a rolling element. A fitting concave portion to fit the rolling element is formed on the other one of the inner circumference of the outer tubular portion and the outer circumference of the inner tubular portion. With this, the torque value generated when the rolling element leaves the fitting concave portion can be accurately set just by setting the depth of the fitting concave portion. The radial force that acts on the opposite direction of the tubular portions holding the rolling element can be reduced. This allows the strength of the tubular portions to be reduced, and the weight to be lightened. As the torque is not conveyed with frictional force, the wear is also reduced.
