Abstract
A gear transmission comprises an external gear and an internal gear that rotates eccentrically relative to the external gear while meshing with the external gear. At least one first recess is formed on an outer peripheral side of the internal gear so that at least a portion of a motor is disposed within the first recess, thereby shortening the length and width of the device that includes the motor and the gear transmission in the axial and radial direction, respectively.
