ABSTRACT:
In a differential gear apparatus provided with a differential limitation mechanism, to prevent a washer interposed between the differential case and the coupling case from being seized by heat when viscous fluid is sheared into high temperature and pressure, the coupling case is formed integral with a first output shaft to increase rigidity of the coupling case. Further, it is preferable to form an inner hub integral with a second output shaft to increase rigidity of the inner hub.
