Abstract
A torque detector is provided, which functions in such a manner that as torque is applied between an input shaft and an output shaft, an angular displacement is produced between the input shaft and the output shaft, this angular displacement is converted into an axial displacement by means of a torque-axial displacement converting mechanism to bend a cantilever fixed between a housing and the torque-axial displacement converting mechanism, by means of a strain gage attached to the cantilever the deformation of the cantilever is converted into a change of electric resistance, and by causing a current to flow through the strain gage the torque applied between the input shaft and the output shaft is converted into a voltage.
