遊星歯車増減速機。[Claims for Utility Model Registration] Three or more eccentric bodies provided on an input rotating shaft, an external gear fitted to the eccentric bodies through rollers having at least an inner ring, and the external gears. Consisting of an internal gear that internally meshes with the gear, a shaft that penetrates the external gear and supports it eccentrically, and a holder that fixes the shaft, and fixes either the internal gear or the holder. In a planetary gear speed reducer in which deceleration rotation or speed-up rotation is taken out from the other, the eccentric body is integrally formed on one eccentric body shaft, and the eccentric body at the endmost part of the eccentric body The outer periphery of the body is formed to be smaller than the outer periphery of the adjacent eccentric body to constitute a small circular eccentric body, and the small circular eccentric body has a ring smaller than the inner circumferential ring fitted to the other eccentric body. A planetary gear speed reducer characterized by a thick inner circumferential ring fitted together.
