A correction circuit (88a) receives a steering torque (Trqs) and an electric signal (Sc) indicative of an operating state of a clutch (12). The correction circuit (88a) selectively uses a first correction value (Td) and a second correction value (Te) in accordance with the operating state of the clutch (12). The first correction value (Td) is set to correct deviation of the steering torque (Trqs) relative to its zero point when an exciting coil of the clutch (12) is not energized. The second correction value (Te) is set to correct deviation of the steering torque (Trqs) relative to its zero point, caused by magnetic flux generated by energization of the exciting coil of the clutch (12). Adding the first correction value (Td) or the second correction value (Te) to the steering torque (Trqs) in accordance with the operating state of the clutch (12) suitably corrects deviation of the steering torque (Trqs) relative to its zero point in accordance with the operating state of the clutch (12).
