This rotary driving device can be used as a driving device in a bicycle for example. Without utilizing the conventional device wherein a chain, a sprocket and the like are used, a rocking movement of a pair of rocking arms connected to the input shaft makes it possible to advance the bicycle.Field of SearchScrew and nut devices | |
