PURPOSE:To increase the deceleration of an output shaft by connecting the input shaft side to a differential gear box through a planetary gear reduction mechanism and decelerating the revolution on the input shaft side and transmitting said revolution onto the right and left output shafts. CONSTITUTION:A small bevel gear 2 fixed onto an input shaft 1 is fitted with a large bevel gear 3, and said large bevel gear 3 is fixed onto a cylindrical housing 4. And said housing 4 is connected with a differential gear box 6 through a planetary gear reduction mechanism 5, and a pair of differential small bevel gears 7 and 7 and a pair of differential large bevel gears 8 and 8 are installed into the differential gear box 6. The right and left output shafts 9 and 9 connected with a pair of differential large bevel gears 8 and 8 are connected with a driving wheel 11 through a final reduction gear mechanism 10. Therefore, the revolution on the input shaft 1 side is decelerated with a large reduction rate, and transmitted to the differential gear box 6, and the reduction rate of the right and left output shafts 9 and 9 is increased, and a large torque can be obtained by the low speed revolution of the driving wheel 11, even if the final reduction gear mechanism 10 is a common one-stage planetary gear type.
