摘要： A torque measuring device including a light irradiation element for irradiating a light, and a control unit operatively connected to the irradiation element so as to branch the light into a plurality of lights as beams and control a beam diameter of the respective lights so as to irradiate the lights on a surface of a member to be measured. The torque measuring device further includes a plurality of reflectors disposed on the surface of the member to be measured so as to change reflection state of the respective lights, a plurality of detectors for detecting the changes of intensities of the respective reflected lights and generating signals thereof, and a signal processor for processing the generated signals and operating a rotation period on the basis of the generated signals thereby to calculate a torque of the member to be measured.
