Claims

[Claims for Utility Model Registration] A motor rotation detection device comprising a potentiometer that detects the rotation speed and direction of the motor, and a transmission means that transmits the rotation of the output shaft of the motor to the rotation shaft of the potentiometer. In the above, the transmission means is composed of a joint connected to the output shaft of the motor and the rotating shaft of the potentiometer, respectively, and the projecting end of the output shaft of the motor has a circular cross section formed in the joint. A motor rotation detection device characterized in that a rotation detecting device is provided that connects a joint and an output shaft of a motor by fitting into a shaped connection hole, and prevents relative rotation between the joint and the output shaft of the motor. .
