PROBLEM TO BE SOLVED: To provide a fitting method of a magnetic yoke assembly that enables attainment of improving detection accuracy of a torque detector, and the magnetic yoke assembly.SOLUTION: A magnetic yoke assembly 26 that constitutes a torque detector for detecting torsional torque inputted to a part between two coupled shafts is fitted to one shaft of the two shafts. The magnetic yoke assembly 26 comprises: a pair of yoke rings 34 and 35 in which multiple magnetic pole claws 37 and 38 are disposed at equal intervals in an inner circumference thereof; and a holding cylinder 36, a cylindrical resin molding, which retains the pair of yoke rings 34 and 35 in a state of being positioned so as to alternately arrange the mutual magnetic pole claws 37 and 38. A recess 47 formed on the holding cylinder 36 as a pullout hole of a jig for positioning the pair of yoke rings 34 and 35 relative to each other during molding of the holding cylinder 36 is used as a positioning part for positioning the magnetic yoke assembly 26 at the one shaft.

    【課題】トルク検出装置の検出精度の向上を図ることができる磁気ヨークアセンブリの取り付け方法および当該磁気ヨークアセンブリを提供すること。【解決手段】連結された2つの軸の間に入力される捩じれトルクを検出するためのトルク検出装置を構成する磁気ヨークアセンブリ26を、2つの軸における一方の軸に取り付ける。磁気ヨークアセンブリ26は、複数の磁極爪37,38が内周に等間隔で配置された一対のヨークリング34,35と、一対のヨークリング34,35を互いの磁極爪37,38が交互に並ぶように位置決めした状態で保持する円筒状の樹脂成形品である保持筒36とを含む。保持筒36の成形時に一対のヨークリング34,35同士を位置決めする治具の抜き痕として保持筒36に形成された凹部47を、磁気ヨークアセンブリ26を前記一方の軸に位置決めするための位置決め部として用いる。【選択図】図5
