PROBLEM TO BE SOLVED: To obtain a resolver which suppresses non-uniform deformation in a peripheral direction of an outer detection surface of a resolver rotor.SOLUTION: A resolver is constituted by a resolver having a plurality of salient pole parts in the outer periphery and a shaft fixing hole press-fitted and fixed to a rotation shaft in a center part, and is formed with a laminated steel plate and a resolver stator provided by surrounding the resolver rotor coaxial with this resolver rotor. The rotation angle of the rotation shaft is detected by the change of a gap permeance between the resolver rotor and a resolver stator. The resolver rotor is provided with a laminate caulking part for caulking a laminate steel plate for each salient pole part, and the inner peripheral surface of the shaft fixing hole is provided with a protrusion plastically deformed when press-fitting the resolver rotor in association with the laminate caulking part, and the projection and the laminate caulking part associated with each other are arranged on the same diameter line of the shaft fixing hole.SELECTED DRAWING: Figure 2

    【課題】レゾルバロータ外側検出面の、周方向の不均一な変形を抑制したレゾルバを得る。【解決手段】外周に複数の突極部と中央部に回転軸に圧入固定される軸固定孔とを有し積層鋼板で形成されたレゾルバロータと、このレゾルバロータと同心でレゾルバロータを囲って設けられたレゾルバステータとによって構成され、レゾルバロータとレゾルバステータとの間のギァップパーミアンスの変化により回転軸の回転角度を検出するレゾルバにおいて、レゾルバロータには、突極部ごとに積層鋼板をかしめる積層カシメ部を設けると共に、軸固定孔の内周面には、レゾルバロータの圧入時に塑性変形する凸部を積層カシメ部に対応して設け、且つ対応する凸部と積層カシメ部とを、軸固定孔の同一径線上に配置したものである。【選択図】図2
