Abstract

PURPOSE:To provide a sufficient marginal space for serration jointing and lower a limit of interference between a generator element and a bottom face of a yoke having a boss member jointed by serration. CONSTITUTION:A peripheral part of an opening 26 at a bottom wall 25 of a yoke 20 is bent inward in the axial direction of the yoke 20 so that a fitting part 27 is projected to an inner peripheral face of the yoke 20. Then, the fitting part 27 is pushed back outward in the axial direction of the yoke 20 though plastic deformation so that a bent part 28 in bending is diminished, and a height L1 is lowered to a height L2 in the axial direction. A female serration 29 is formed on the inner circumference of the fitting part 27. A male serration of a boss member is jointed with the female serration 29 and a buckling caulking part is formed at the top of the boss member. Consequently, a limit of interference with a generator element is reduced because the height of the fitting part 27 is reduced by a pushed-back extent, and in the fitting part 27 only the bent part 28 is diminished, so an effective length of the female serration is not reduced.

Further, in the case of the same interference limit dimension, the length of the fitting portion 27 of the yoke 20 can be shortened from L 1 to L 2 , so that the core thickness should be increased accordingly. It is possible to improve the output of the rotor.

On the other hand, although the length of the fitting portion 27 in the axial direction is shortened, the length S 2 of the flat inner peripheral surface is equal to the effective length S 0 of the female serration 29 formed on the inner peripheral surface. Can be maintained. Therefore, the boss member 11 can be securely fixed to the yoke 20 by the serration connection. As a result, the manufacturing cost can be reduced more than when the boss member is fixed to the yoke by using the rivet.
