PURPOSE:To provide the reduction in gear noise by decreasing the deflection of a transmission shaft due to some load as well as the reduction in the size of a transmission case. CONSTITUTION:The first and second transmission shafts 3, 4 are disposed in a transmission case 2, both the end parts in an axial direction of the first and second transmission shafts 3, 4 are rotatingly-supported by the transmission case 2 through bearings 5, 5', and transmission gears 6a-10a at plural stages are fitted onto the first and second transmission shafts 3, 4 to form a transmission 1. With this constitution, transmission gears 10a, 10b at the highest speed stage are disposed in the roughly middle part between the bearing 5, 5' of the transmission shafts 3, 4. |
