Abstract
Axial positions of two driven external gears making up each of a plurality of paired-gear groups with respect to an input shaft are made identical, and a different paired-gear group is arranged by being offset in the axial direction of the input shaft . Therefore, only two driven external gears making up the paired-gear group are present at an identical axial position of the input shaft . Consequently, even if the diameters of these driven external gears are made large up to the very limit, these driven external gears do not interfere with each other. Accordingly, it is possible to readily enlarge the reduction ratio based on the driving and driven external gears and
