ABSTRACT:
Disclosed is a differential gear assembly having: a rotatable case; first and second side gears being coaxially supported in the case and connected to first and second output shafts, respectively; at least one pair of first and second pinion gears, the first pinion gear having first and second gear portions, the second pinion gear having third and fourth gear portions, the first and second pinion gears being arranged in parallel to the rotation axis of the case so that the first gear portion is engaged with the third gear portion, the second gear portion is engaged with the first side gear, and that the fourth gear portion is engaged with the second side gear; and a holding member being provided on the case for holding the first and second pinion gears. The first and second pinion gears move with the case around the rotation axis in response to rotation of the case and each of the first and second pinion gears is slidable and rotatable around an axis thereof with respect to the holding member. The first and third gear portions move around the rotation axis within a first cylindrical scope which is located at one of axially outer sides of a second cylindrical scope containing the first and second side gears.
