ABSTRACT:
A torque detecting device includes an elastic member disposed between an input shaft and an output shaft of a torque transmitting apparatus, first and second resolvers detecting rotational angles of the elastic member at sides of the input shaft and the output shaft. The first resolver includes a first excitation winding coil and a first output winding coil, and the second resolver includes a second excitation winding coil and a second output winding coil. The first and second excitation winding coils are connected to a ground, and the first and second output winding coils are connected to the other ground.
