Abstract
The present invention provides a differential gear which is capable of constructing an axle supporting structure at a low cost and obtaining a differential limiting effect without adding a special mechanism. In the present invention, each axle is coupled to the main body of the differential gear by regulating movement of each axle in the insertion direction and the counter-insertion direction by both a regulating member engaging with each axle and a regulating member interposed between the end surfaces of the axles. In this case, differential motion is achieved by both grooves provided in a pair of rotating bodies which rotates integrally with drive shafts and a plurality of balls 5 which roll along the grooves, and the differential motion is limited by the reactive force generated between each groove and the rolling bodies. Thus, a differential limiting effect is obtainable without adding a special mechanism.
