ABSTRACT:
A low-noise speed reduction device that is simple in structure, small-sized, and little in energy loss is provided. Two-stage gears, i.e., a large-diameter gear65and a small-diameter gear66of a third external gear63are supported by a supporting shaft59, and one-stage second external gear58that meshes with the small-diameter gear66is only attached to an axial one end of a crankshaft40. Therefore, the axial length of the whole speed reduction device becomes short, and consequently, miniaturization becomes possible. Further, since gears mesh with each other only in two places until a driving force is transmitted to the crankshaft40from the first external gear54, noises can be reduced, and energy loss can also be lowered.
