PROBLEM TO BE SOLVED: To provide an adjusting method for steering device and an adjusting device for steering device such that a clearance between a support yoke and a yoke plug can be set more suitably.SOLUTION: A yoke plug 22 temporarily fastened enough to cause a support yoke to elastically have compressive deformation is unfastened up to an angle position θ1 in a stable region where displacement E does not change in a direction crossing the axis of a rack shaft 12 against variation in angle position θ of the yoke plug 22. At this time, an inflection point Pi as a border point where a rate of variation in displacement E of the rack shaft 12 to variation in angle position θ of the yoke plug 22 abruptly decreases is found, and a target angle position θ3 corresponding to a target clearance is set based upon an angle position θ2 corresponding to the inflection point Pi. Then, after the yoke plug 22 is unfastened again up to the target angle position θ3 after the yoke plug 22 is unfastened up to an angle position θ4, the yoke plug 22 is unfastened up to the target angle position θ3.SELECTED DRAWING: Figure 5
【課題】サポートヨークとヨークプラグとの間のクリアランスをより適切に設定することができるステアリング装置の調整方法およびステアリング装置の調整装置を提供する。【解決手段】サポートヨークに弾性的な圧縮変形が生じる程度に仮締めされたヨークプラグ22を、ヨークプラグ22の角度位置θの変化に対してラック軸12の軸線に交わる方向における変位Eが変化しなくなる安定領域の角度位置θ1まで緩める。このとき、ヨークプラグ22の角度位置θの変化に対するラック軸12の変位Eの変化割合が急激に減少する境界点となる変曲点Piを求め、この変曲点Piに対応する角度位置θ2を基準として目標クリアランスに応じた目標角度位置θ3を設定する。次いでヨークプラグ22を目標角度位置θ3に満たない角度位置θ4まで締め付けた後、再びヨークプラグ22を目標角度位置θ3まで緩める。【選択図】図5
