ABSTRACT:
This invention provides a differential gear that permits a sure differential limitation effect to be obtained with a simple structure and that is both compact in size and low in price. That is, when a rotational difference occurs on a pair of output-side rotary bodies arranged in opposite form to each other on the shaft center of an input-side rotary body, a differential rotation of each output-side rotary body is achieved by interconnecting the rotary motion of each output-side rotary body by means of numerous grooves and numerous balls fitted to these grooves. At this time, when the force necessary to cause a rotational difference is given to each output-side rotary body only from one output-side rotary body, the balls or grooves of the driven side at differential rotation cause the grooves or balls of the driving side to follow their own motion on the other output-side rotary body. Consequently, the reaction force caused at this time acts as a resistance to limit the differential rotation of each output-side rotary body. Accordingly, this invention permits a very stable differential limitation effect of torque sensitizing type to be obtained without requiring any special mechanism for this purpose.
