A torque detecting apparatus including, for each of an input shaft 23 and an output shaft 18 that are connected with a torsion bar 5, detecting means 1, 2 for detecting regions of a plurality of targets 7, 9 arranged so that the regions to be detected change periodically and continuously with rotation of rotors 6, 8, for detecting a torque applied to the input shaft 23, based on a difference between the detected regions resulting from twist of the torsion bar 5. The torque detecting apparatus includes: means 11 for obtaining a correction amount for each of the targets 7, 9 so as to correct detected regions upon one rotation of the rotors 6, 8, based on the maximum values of signals indicating the regions of each of the targets 7, 9 detected by the detecting means 1, 2; storing means 12 for storing the correction amounts; and means 11 for correcting the regions detected by the detecting means 1, 2 based on the correction amounts stored in the storing means 12 for the targets 7, 9 discriminated by the discriminating means 11. Accordingly, it is possible to realize a torque detecting apparatus capable of restraining the influence of rotational deflection and detecting a more accurate steering torque.
