摘要： Pinion gears are rotatably carried within pinion gear receiving openings formed in a differential case. The inner pinion gear holding surfaces of the receiving openings are enlarged inwardly to form extensions to hold not only portions of the pinion gears that are located outwardly and that are to be held, but also part of inner meshing portions of the pinion gears that are disposed in meshing engagement with side gears in an overlapping manner. This construction prevents a tilting of the pinion gears and improves the durability.

摘要： A plurality of pinion gears 4A, 4B which are rotatably held within a differential case 2, a pair of left and right side gears 6L, 6R disposed in meshing engagement with the pinion gears and connected to left and right axles, respectively, and thrust washers 16L, 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 opening 2b in 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 holders 12A, 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.

摘要： Five receiving holes 2e extending along the axis of a circular cylindrical portion 2b of a housing are formed in the circular cylindrical portion 2b. Those five receiving holes 2e are arranged at equal intervals in the peripheral direction of the circular cylindrical portion 2b. Each receiving hole 2e rotatably receives therein a planetary gear 5. The respective planetary gears 5 are in engagement with an inner gear 3 and a sun gear 4. The teeth of the inner gear 3, the sun gear 4 and the planetary gears 5 are helical teeth. The numbers of teeth of the inner gear 3, the sun gear 4 and the planetary gears 5 are set to 36, 24 and 6, respectively. As a result, the numbers of teeth of the inner gear 3 and the sun gear 4 located between adjacent two planetary gears 5 in the peripheral direction become 7.2 and 4.8, respectively, which are values each having a fraction below the decimal point.

摘要： A planetary gear 5 is contacted at its at least one tooth of all its teeth 51n with an end edge 23d facing an inner releasing part 23c of an inner peripheral surface of a receiving hole 23a irrespective of a rotational position of the planetary gear 5. By doing so, the planetary gear 5 is prevented from moving in the radial direction. As a result, the planetary gear 5 can be prevented from vibrating in the radial direction. Thus, vibrations of a planetary gear apparatus can be reduced, and the planetary gear and a carrier can be reduced in damage.
