PROBLEM TO BE SOLVED: To provide a steering device capable of reducing a load of a drive control part for controlling a motor assisting the rotation of an input shaft, detecting an abnormal state in a torque calculation part and outputting the abnormal state to the drive control part, and selecting a type of output signal from the torque calculation part between analog signal and a digital signal. SOLUTION: The torque calculation part 30 has a hardware structure separate from the drive control part 20 for controlling the motor M to assist the rotation of the input shaft 3a, and provided with input terminals 36, 36,... to each of which a ignition signal, vehicle speed signal and engine rotation signal and the like are inputted, a communication port P to communicate with the drive control part 20, a digital output terminal 34 and an analog output terminal 35 to output the calculated rotation angles and rotation torque as a digital signal or an analog signal. |
