PURPOSE:To provide a single-shaft type electric automobile reduction gear whose axial direction size can be shortened. CONSTITUTION:Since the pinion gear shaft 48 of a planetary gear type differential gear 18 is directly supported by the outer race 50L of a left side first uniform speed joint, a conventional carrier for supporting the pinion gear shaft 48 is no more necessary, thereby, the outer race 50L serves also as the carrier for supporting the pinion gear shaft 48. Accordingly, in the conventional automatic automobile reduction gear, the spline fitting between a boss on the carrier and a connecting shaft of the uniform speed joint is not needed, so that the axial direction size WL can be shortened to an extent where the carrier and the connecting shaft have occupied conventionally, and the loading capacity of vehicles can be improved.
