ABSTRACT:
A torque measuring device for a rotating body comprises: a rotary section including first and second flanges provided respectively at driving and driven sides, and a hollow cylinder provided between the first and second flanges; light emitting elements provided at an outer circumference of the rotary section, and adapted to emit light based on output from each of torque detectors provided at an inner surface of the hollow cylinder thereby sending an optical signal; a light conductive member to receive the optical signal at a light receiving surface thereof, and to guide the optical signal along its longitudinal directions; and a torque calculator to calculate torque of the rotary section based on the optical signal guided by the light conductive member, wherein the light conductive member has an optical path converting means formed at either the light receiving surface or a surface thereof opposite to the light receiving surface.
