PURPOSE:To obtain the speed changing device having a short shaft length by improving the arrangement of the shafts. CONSTITUTION:The shafts 3, 4 are arranged in parallel with an input shaft 2 respectively. The input shaft 2 supports a hollow shaft 11 coaxially and rotatably arount it. The input shaft 2 and the shaft 3 are connected through a pair of gears 12, 13 while the input shaft 2 and the shaft 4 are connected through a pair of gears 12, 14 to drive them. A speed changing gear train, meshing at all times, is provided between the shaft 3 and the hollow shaft 11 as well as the shaft 4 and the hollow shaft 11 while a rotating power inputting into the input shaft 2 is changed in the speed thereof and is outputted out of an output gear 51 supported rotatably on the shaft 4. |
