PURPOSE:To contrive fuel cost reduction through shortening the full length of the speed change gear, improving the assembly ability, and reducing the dragging torque close by connecting three shafts to be coupled to a planetary geared speed change gear and to a differential gear mutually by means of a chain transmission gear. CONSTITUTION:A first planetary geared speed change gear 2 is arranged between an input shaft 21 and an output shaft 22. A planetary geared speed change gear 3 is arranged between an input shaft 31 and an output shaft 32. The output shaft 22 and the input shaft 31 are maintained their transmission relationship by means of a chain transmission gear 5. Besides, the output shaft 32 and a drive gear wheel 41 of a differential gear 4 are maintained their transmission relationship by means of a chain transmission gear 45. |
