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

During the secondary collision in an unfastened state of the fastening mechanism, a second engagement portion (driving member) that moves in a column axial direction integrally with the upper jacket abuts on the second tooth member in an unmeshed state to fracture the guide shaft, and deforms an impact absorbing member via the second tooth member to absorb an impact.
