PROBLEM TO BE SOLVED: To provide a hollow planetary reduction gear which can reduce energy consumption of a motor input end by assisting actuation of a speed reduction mechanism by a planetary gear.SOLUTION: One kind of hollow planetary reduction gear has a body 1, and at the body, at least one drive gear 22 is provided. Each drive gear drives by a power input source, and a transmission gear 23 is connected to each drive gear, and also, each transmission gear is connected to a first gear 21. From a gear ratio between the drive gear, the transmission gear and the first gear, an effect of speed reduction generates. Also, a hollow tube part 7 is penetrated in the body, and accommodates a wire.SELECTED DRAWING: Figure 6 |
