In an axle assembly, a differential gear device includes a ring gear and a differential cage. The ring gear has a gear portion formed on a first side surface thereof, which first side surface faces the input shaft and is positioned along the axis of the driving axles, for being operatively connected with the input shaft, and forms an axle hole through which an inner end of one of the right and left driving axles relatively rotatably passes. The differential cage is relatively non-rotatably connected with the ring gear via a second side surface of the ring gear, which second side surface faces away from the input shaft and is positioned along the axis of the driving axles. The differential case also forms therein an axle hole through which an inner end of the residual one of the right and left driving axles relatively rotatably passes, so that the inner ends of the right and left driving axles face to each other.
