Claims

[Claims for Utility Model Registration] An output shaft that receives the rotation of the motor that is decelerated and transmitted by a gear mechanism through a final stage gear, and a resistance value that is connected coaxially with this output shaft and that increases as the output shaft rotates. A servo motor device having a variable resistor that changes the output shaft, wherein a bearing for the output shaft is provided around the shaft of the variable resistor, and a coupling shaft interposed between the shaft of the variable resistor and the output shaft. furthermore, the engagement hole of the coupling shaft with the shaft of the variable resistor and the engagement part of the coupling shaft with the output shaft are formed in a flat shape orthogonal to each other, and the engagement hole and a servo motor device, wherein the engaging portion is set to be movable by a minute distance in a direction perpendicular to the axial direction of the variable resistor.
