Claims

[Claims for Utility Model Registration] A torque detection cylinder member having a hollow cylinder shape, one end surface of which is concentrically connected to a torque transmission shaft, and a torque detection cylinder member which is arranged concentrically within the hollow of the torque detection cylinder member, and whose -thick end is concentrically connected to the torque transmission shaft. , a torque detection rod member connected to an end surface opposite to the end surface of the torque detection cylinder member and whose other end is concentrically connected to another torque transmission shaft; and a connection between the torque detection cylinder member and the torque transmission shaft. A first disc having a light-transmitting part and a light-shielding part disposed on the circumference, which is adhered concentrically to the torque detection tube member near the connection part; and the torque detection rod member and the other A light-transmitting portion and a light-shielding portion are disposed on the circumference near the connection portion with the torque transmission shaft, and are bonded concentrically to the torque detection rod member and facing the first disc through a gap. a second disc that illuminates the second disc; a light-emitting unit that irradiates the second disc and the first disc; and a light-emitting unit that directs light from the light-emitting unit to the first disc and the second disc. A torque detector comprising: a photodetector that detects the torque via the photodetector.
