The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “BACKGROUND ART “Industrial robots employ a joint structure in which a multiplicity of joints ha ve the freedom of motion. The motion is provided to a joint through an actuator motor, a servo motor, and the like. In a usual configuration of a robot joint, a reducer is installed on an output terminal of a servo motor to obtain a high-ou tput torque from the servo motor or the like. “The industrial robots employ a harmonic drive technique or a cycloidal drive te chnique in order to fully or partially decrease robot motion. Of these, the cycl oidal drive technique is used in various ways in various industrial fields. In a structure to which the cycloidal drive technique is applied, a cycloidal disc i s rotated with external teeth thereof being engaged with internal teeth of an ou tput shaft. Accordingly, rotational power of an input shaft is reduced, and thus the reduced rotational power is transferred to the output shaft. Through this s tructure, a great torque is made transferable, and a configuration where a reduc tion ratio is increased can be employed.
