ABSTRACT:
A plurality of pinion gears4A,4B which are rotatably held within a differential case2, a pair of left and right side gears6L,6R disposed in meshing engagement with the pinion gears and connected to left and right axles, respectively, and thrust washers16L,16R interposed between the rear surfaces of the side gears and the internal surface of the differential case are provided. The differential case is of a one-piece type, and is formed with an opening2bin its sidewall, which is used in assembling the pinion gears and the like. The internal surface of the differential case is formed with pinion gear holders12A,12B. The pinion gears are inserted, followed by the insertion of the side gears. The side gears are spaced from the pinion gears by an amount corresponding to the thickness of the thrust washers, and this allows the side gears to be inserted in following relationship with the pinion gears.
