Abstract
A speed reduction device includes an input shaft, a fixed internal gear, an output internal gear and a planetary two-stage gear. The fixed internal gear is fixed on the input shaft. The output internal gear is rotatably disposed on the same axis as the fixed internal gear and has a different number of teeth from the fixed internal gear. The planetary two-stage gear is supported by the input shaft so as to be rotatable around an eccentric shaft. The planetary two-stage gear has a large diameter gear and a small diameter gear which are respectively meshed with the fixed internal gear and the output internal gear. A difference in number of teeth between the large diameter gear and the small diameter gear is equal to a difference in number of teeth between the fixed internal gear and the output internal gear.
