ABSTRACT:
A torque measuring apparatus includes a rotor having a hollow body portion formed between a drive-side flange portion and a load-side flange portion. Light emitting elements are disposed on a periphery of the rotor, for emitting optical signals based on an output from a torque detection unit attached to a hollow portion of the hollow body portion. A transparent plate attached to a chassis is disposed outside the rotor, for allowing the optical signals to pass therethrough, and a signal receiving unit is arranged on the chassis, for receiving the optical signals via the transparent plate, wherein the transparent plate is detachable from the chassis.
