Abstract
A torque detecting device includes a first rotary member connected to an input shaft and a second rotary member connected to an output shaft and arranged coaxially with the first rotary member. An elastic member is sandwiched between the first rotary member and the second rotary member and deforms according to the torque acting thereon. A sensor is arranged confronting the first and second rotary members to detect their rotational phases and a torque computer computes the torque by determining the rotational phase difference between the first and second rotary members from the rotational phases as detected by the sensor.
