Abstract
Output signals of a torque sensor include a first output signal used in an assist control and a second output signal used in controls other than the assist control. An adjusting device of an electric power steering device includes an input torque meter for measuring an input torque applied to the input shaft, an output torque meter for measuring an output torque output by the steering mechanism, and a sensor output corrector for correcting an output signal of the torque sensor. The sensor output corrector corrects the first output signal so that a relationship between the input torque measured by the input torque meter and the output torque measured by the output torque meter becomes an ideal characteristic set in advance, and corrects the second output signal so that an input torque detected by the torque sensor coincides with the input torque measured by the input torque meter.
