ABSTRACT:
An orthogonal axis gear, a planetary gear reduction mechanism portion, and a differential gear mechanism portion are arranged along an axial center direction of left and right output shafts. The planetary gear reduction mechanism portion is constituted such that a sun gear thereof is provided as a continuation of a crown gear of the orthogonal axis gear, a ring gear thereof is fixed to a differential case, and a planetary carrier thereof serves as an output. Further, the differential gear mechanism portion employs a planetary gear mechanism and is constituted such that a ring gear of the planetary gear mechanism is provided as a continuation of the planetary carrier of the planetary gear reduction mechanism portion, a planetary carrier thereof is provided as a continuation of the left side output shaft, and a sun gear thereof is provided as a continuation of the right side output shaft.
