PROBLEM TO BE SOLVED: To reduce a magnetic resistance between teeth and a yoke. SOLUTION: The teeth (200) to be arranged in an annular shape are individually formed by laminating second magnetic plates 202 radially. Each tooth 200 includes a first trapezoidal body 212 having an upper bottom, in which one second magnetic plate 202 arranged at a position closest to an axis in a top plan view has a length Ln in a first direction, and a lower bottom, in which another second magnetic plate 202 arranged at the position radially outside of the one second magnetic plate 202 has a length Lf (wherein Ln
