Abstract

A torque detector for detecting a torque applied to a load from a driving shaft is disclosed. The torque detector comprises an elastic member which is interposed between a first shaft connected to the driving shaft and a second shaft connected to the load so as to be connected thereto, an angular phase difference detecting means for detecting an angular phase difference occurring between the first shaft and the second shaft when the torque is transmitted from the first shaft to the second shaft through the elastic member, and a data processing means for calculating the torque from the detected angular phase difference.
