ABSTRACT:
A flat belt 6 is wound around between an annular friction surface 2 at a periphery of a first rotatable member 1 and an arc-like friction surface 4 of a rocking portion 3 of a second rotatable member 5 which is relatively rotatably supported on the first rotatable member 2, and an initial tension is applied to the flat belt 6. With relative rotation movement between the rotatable members 1 and 5 in a locking or free direction, the rocking portion 3 is rocked around a rocking axis Q by the flat belt 6. By virtue of such rocking movement of the rocking portion 3, the tension of the flat belt 6 is increased up to a higher value than the initial tension or decreased down to a lower value than the initial tension. This permits connection or disconnection of the transmission of torque between the rotatable members 1 and 5 in dependence on the relative rotational direction of the rotatable members 1 and 5. The present invention provides a novel one-way clutch simple in structure, not calling for high precision components, less likely to fail to operate properly due to an excessive input torque, requiring only replacement of components even when failing to operate properly, capable of variation in maximum transmission torque, and low in cost.
