ABSTRACT:
A torque detector, for detecting a torque applied to a torque transmission shaft which is connected to a load such as a wheel of an automobile, comprises a first rotating member which is integrally connected to a driving shaft of an engine, a second rotating member which is integrally connected to a load so as to be opposed to the first rotating member, a plurality of elastic members for connecting the opposed surfaces of the first and second rotating members, an angular phase difference detecting circuit for detecting the angular phase difference between the first and second rotating members, a no load condition detecting circuit for detecting a no load condition of the engine, and a data processor for calculating torque from the angular phase difference between the first and second rotating members under the load condition and under the no load condition. An accurate value of applied torque is detected by subtracting the angular phase difference under the no load condition from the load condition.
