PROBLEM TO BE SOLVED: To easily achieve desired hydraulic pressure characteristic in a manufacturing method of a hydraulic control valve for controlling supply and discharge of a working fluid pressure of a power cylinder of a hydraulic power steering device.SOLUTION: A manufacturing method of a hydraulic control valve 18 includes a positioning process and a fixing process. In the positioning process, a valve body 31 is positioned on a place to achieve a desired hydraulic pressure characteristic with respect to a housing 30 by operating the valve body 31 before fixed in the housing 30 of a pressure control valve 18 from the outside of the housing 30 through an operating member 48 by using, for example, a positioning tool T (Fig.3(b)), and in the fixing process, the valve body 31 after the positioning, is fixed to the housing 30 by using, for example, a fastening tool such as a spanner S (Fig.3(c)).

    【課題】油圧パワーステアリング装置のパワーシリンダの作動油圧を給排制御する油圧制御弁の製造方法において、所要の油圧特性を容易に得る。【解決手段】油圧制御弁18の製造方法が、位置決め工程と、固定工程とを含む。位置決め工程では、圧制御弁18のハウジング30内で固定される前のバルブボディ31を、ハウジング30外から、例えば位置決め工具Tを用いて操作部材48を介して操作することにより、ハウジング30に対してバルブボディ31を所要の油圧性能が得られる位置に位置決めする[図3(b)参照]。固定工程では、例えばスパナSである締付工具を用いて、位置決め後のバルブボディ31をハウジング30に固定する[図3(c)参照]。【選択図】図3
