摘要：
In a torque sensor, a torque signal and a monitoring signal have values between a first lower limit and a first upper limit. A limiting section changes the torque signal to a second lower limit when the torque signal is equal to or less than the second lower limit that is greater than the first lower limit, and changes the torque signal to a second upper limit when the torque signal is equal to or greater than the second upper limit that is less than the first upper limit. When abnormality has occurred in the torque signal, an output section transmits a first fault notification signal that is a value between the first and second lower limits or a second fault notification signal that is a value between the first and second upper limits.
