Abstract
PURPOSE:To obtain an annular magnet having an anisotropy with respect to the central symmetry by annularly disposing anisotropic circular-arc magnetic pieces with upper and lower ends formed in the prescribed oblique surfaces and integrally molding the V-shaped gaps and the creeping surfaces of the upper and lower contacts with synthetic resin. CONSTITUTION:Both end enters 6a of the anisotropic circular-arc-shaped magnet pieces 6a molded in a parallel magnetic field are radial planar surfaces 6a, both the upper and lower ends are the prescribed oblique surfaces 6b, 6c, and the anisotropic circular-arc-shaped magnetic pieces 6 are annularly disposed. Synthetic, resin is molded at the gap (V-shaped groove gap) of triangular shape formed at the upper and lower contacts of the pieces 6 and both side surfaces of the annular magnet are molded with synthetic resin, and the synthetic resin connecting rods 10a, 10b of the upper and lower contacts of the magnetic pieces and the synthetic resin collars 9a, 9b are integrally formed. The anisotropic annular magnet 11 exposed only at the inner and outer magnetic poles surfaces is engaged fixed with the inner surface of the iron hub drum of the prescribed bicycle.
