To provide a positioning device for a stator core, having compact structure and enabling positioning of the stator core.SOLUTION: A positioning device 1 for a cylindrical stator core 100 positioning a plurality of magnetic steel sheets is provided, wherein the cylindrical stator core 100 is formed by laminating, in a sheet thickness direction, the plurality of magnetic steel sheets having an annular stator core main body portion and a plurality of teeth 103 extending to a radial direction inner side while being positioned in an inner peripheral side of the stator core main body portion. The positioning device includes: a plurality of positioning members 10 that is positioned in the radial direction inner side of the plurality of teeth 103, and comes in contact with a radially inner end surface 103a of the plurality of teeth 103; a conversion mechanism 3 that converts a rotational driving force to a radial direction; and a motor 8 that generates the rotational driving force. The conversion mechanism 3 moves the plurality of positioning members 10 to the radial direction by the rotational driving force.SELECTED DRAWING: Figure 3 【課題】固定子コアの位置決めを行うことができるコンパクトな構成の固定子コアの位置決め装置を提供する。【解決手段】円環状の固定子コア本体部と、固定子コア本体部の内周側に位置して径方向内方に延びる複数のティース１０３とを有する電磁鋼板が、板厚方向に複数積層された円筒状の固定子コア１００において、複数の電磁鋼板を位置決めする固定子コア１００の位置決め装置１である。複数のティース１０３の径方向内方に位置し、複数のティース１０３の径方向内端面１０３ａに接触する複数の位置決め部材１０と、回転駆動力を径方向の駆動力に変換する変換機構３と、回転駆動力を発生させるモータ８と、を有する。変換機構３は、回転駆動力によって複数の位置決め部材１０を径方向に移動する。【選択図】図３
