Abstract
A gear transmission comprises a crankshaft that eccentrically rotates one of an internal gear and an external gear. A first gear is attached to one end of the crankshaft. A ring gear having internal teeth meshes with the first gear. An intermediate gear meshes with external teeth of the ring gear. A second gear is attached to one end of an output shaft of a motor and meshes with the intermediate gear. The motor and the crankshaft are positioned, relative to the intermediate gear, on the same side in the axial direction of the gear transmission.
