Abstract

PURPOSE: To heighten the degree of roundness, by molding a magnet case of resin together with magnets and providing projections on the bottom of the magnet case and fixing the projections in holes of a yoke and cylindrically or centerlessly grinding the magnet case.
CONSTITUTION: The magnets 11, 11' are coupled to each other. A shaft inserting hole 12 is provided in the center of the magnet assembly. The cylindrical magnet case 13 is made of synthetic resin. At that time, a pair of calking projections 14, 14' and a central projection 15 are produced on the bottom of the cylindrical magnet case. Then, the cylindrical surface of the megnet case is centerlessly ground. The holes for fixing the magnet case are provided in the bottom of the yoke 17 shaped like a bottomed cylinder. The projections 14, 14' and the central projection 15 are inserted into the holes. The projections 14, 14' and the yoke 17 are calked to each other by heating or supersonic waves. Thereby, the molding burr is removed and the degree of roundness of the cylindrical magnet case is heightened. Furthermore, the magnets can be inserted and molded automatically.
