A projecting portionis integrally provided at a first connecting portionof a bobbinThe projecting portionhas a triangular cross-section taken in an orthogonal direction orthogonal to a laminating direction of the steel platesand parallel to magnetic steel platesThe section of the projecting portion is geometrically similar in shape to a cross-section of a fitting recessed portiontaken in the orthogonal direction. The cross-section of the projecting portionis substantially the same in size as or slightly smaller than the cross-section of the fitting recessed portionWith this arrangement, when one ends of six magnetic columnsof a magnetic pole constituent memberare brought into engagement with six fitting recessed portionsprojecting portionspasses through the fitting recessed portionsand come out of the fitting recessed portions
