<p>A torque detector (17) includes a sensor unit (22) including a single magnetic sensor (35) capable of detecting a change of flux, a torque detecting unit (23) that detects torque based on an output of the sensor unit (22), and a magnetic field generator (24) capable of generating a magnetic field in an area including the sensor unit (22). The torque detecting unit (23) has a failure detecting mode that detects an abnormality of the sensor unit (22) based on an offset amount of the output of the sensor unit (22). The offset amount is obtained when the magnetic field is generated by the magnetic field generator (24).</p> |
