PURPOSE:To mount a mounting case and a permanent magnet in a simple work by integrally forming a plane portion to be mounted with a cylindrical housing, engaging a cylindrical mounting case having elasticity with the housing, and press-fitting a field permanent magnet into the case. CONSTITUTION:Four cylindrical yokes 5 are projected by pressing, thereby forming projecting plane portions 5. Mounting cases 6 are respectively press- fitted to the projecting side surfaces 5b of the projecting plane portions 5a. Thereafter, insulating resin 7 is coated on the portion between the plane portions 5a and the cases 6 and on the outer periphery of the plane portions 5a, permanent magnets 8 are respectively press-fitted to the cases 6, the upper ends of the magnets 8 are respectively press-fitted to the resin 7, and assembling is thus completed. |
