PURPOSE:To fix a stator without using a screw and to reduce the number of screw components by a method wherein a column part which is passed through a hole part made in a support part and which can be plastic-deformed is formed at a fixation member, the tip part of the column part is caulked by a caulking method and the stator is fixed. CONSTITUTION:A cylinder part 2 which can be palstic-deformed and which is a hollow column is formed integrally so as to ptrotrude in the center of a rear lid 1, the outside diameter of the cylinder part 2 is formed to be a size in which a spaces 9 and the shaft hole of a stator 3 can be fitted without play, and the cylinder part is formed to be a length protruding from stator 3 situated at the upper stage when the spacer 9 and the stator 3 are fitted. The stator 3 is fitted into the cylinder part 2 of the rear lid 1 in such a way that the spacer 9 is situated at the lower part, a sizing rod 10 is lowered, and a bearing 8 fitted to the sizing rod 10 is force-fitted into the cylinder part 2 by a bearing force-fit jig 11. A curling jig 12 presses the upper end of the cylinder part 2, the upper part of the cylinder part 2 is curled, and the stator 3 is caulked and fixed. |
