Abstract
A differential gear device incorporating an internal meshing type planetary reduction gear has an externally toothed gear carried by a hollow input shaft through an eccentric member and an eccentric bearing, an internally toothed gear meshing with the externally toothed gear, a differential gear box disposed adjacent to the externally toothed gear, and a hollow drive splined at its one end to the externally toothed gear and splined at its other end to the differential gear box. The device also has a left axle and a right axle one of which extends through the hollow input shaft.
