PURPOSE:To reduce a size of an equipment and enable constant detection of a transmitted torque by disposing an elastic member in an annular space formed between a separate boss and a transmission ring, with both ends of the member connected to them, to detect a torsion of the elastic member. CONSTITUTION:A boss 2 firmly fit around a rotation shaft 1 and a transmission ring 3 on the periphery of which belt grooves 4 is formed are coaxially constructed with an annular space 5 between. An elastic memeber 10 is disposed between a support ring 6 which is fixed to the boss 2 and kept by the transmission ring 3 via a bearing 7 and a support ring 10 which is fixed to the transmission ring 3 and kept by the boss 2 via a bearing 9. Detective plates 11, 13 are attached to end faces of the support ring 6 and the transmission ring 3, respectively and provided with detective elements 12, 14 and detectors 15, 16. |
