摘要
This arcuate magnet piece (1) is provided with: coupling side surfaces (6, 7) which are coupled with other adjacently joined arcuate magnet pieces (1A); a curved inner peripheral surface (3); and a curved outer peripheral surface (2) which faces the inner peripheral surface (3). The coupling side surfaces (6, 7) are provided with tip surfaces (6a, 7a) which intersect, at prescribed angles (θ1, θ2), tangents (T1, T2) to the direction of curvature of the outer peripheral surface (2). The coupling side surfaces (6, 7) are polarized such that, in cases when the gaps formed with the coupling side surfaces of the other arcuate magnet pieces (1A) are disposed so as to be substantially parallel, the magnetic poles of the other joined arcuate magnet pieces (1A) are different.
