ABSTRACT:
A torque-index sensor having index sensor and torque sensor closely arranged and integrated therein with lightened interference between them is provided. The invented torque-index sensor is comprised of torque sensor that includes first magnetic sensor arranged beside first annular-shaped magnet and index sensor that includes second magnet arranged beside annular-shaped encoder and second magnetic sensor that are arranged being in-line on common axis; and means for varying magnetic flux, which changes direction of magnetic flux that is generated from second magnet toward first magnetic sensor, positioned between first magnetic sensor in torque sensor and second magnet in index sensor.
