Techniques are taught that minimize the overall length of a device that includes a gear transmission and a motor. The gear transmission comprises a crankshaft that eccentrically rotates one of an internal gear and an external gear, a first gear attached to one end of the crankshaft, a ring gear having internal teeth meshing with the first gear, an intermediate gear meshing with external teeth of the ring gear, and a second gear attached to one end of an output shaft of a motor and meshing 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. |
