Claims

[Scope of utility model registration request]

A drive device is provided that applies a predetermined rotational torque to the pinion, and a signal from a rack and pinion engagement detector detected by the rotational torque of the pinion or the propulsion force of the rack and the tightening torque of the rack guide cap are detected. An automatic steering rack guide clearance adjustment device comprising a control device that controls the rotation of a tightening unit based on a signal from a torque detector and a signal from an angle detector that detects the rotation angle of a rack guide cap.
