することができる。According to the above-mentioned means, the peripheral portion of the opening of the bottom wall of the yoke is bent toward the inside of the yoke to form a fitting portion having a substantially cylindrical shape, and then the bent fitting portion is pushed back. Thus, the length in the axial direction is shortened by the plastic deformation. And the female serration is formed on the inner peripheral surface of the shortened fitting portion, but its axial length does not decrease,
On the contrary, since it increases, even if the yoke and the boss member are connected by serration, the bonding strength of serration can be sufficiently secured.

An opening 26 for inserting a boss member is opened at the center of the bottom wall 25 of the yoke 20. Thereafter, a burring process as a bending process is applied to the peripheral portion of the opening 26 in the bottom wall 25 of the yoke 20, and as shown in FIG.
The peripheral portion of 6 is projected inward in the axial direction of the yoke 20, whereby the fitting portion 27 is formed into a short, substantially cylindrical shape.

A curved portion 28 is formed by a burring process at the connection portion with. Since the curved portion 28 is formed by burring, the wall thickness t 1 of the curved portion 28 in this state is the wall thickness t of the yoke bottom wall 25.
It is equal to 0 or thin.

Since the wall thickness of that portion shifts when decreasing from R 2 to R 2 , the wall thickness t 2 of the curved portion 28 becomes thicker than the original wall thickness t 1 accordingly .

As for the effective length S 0 of the female serration 29, the effective length (corresponding to a flat length) S 2 of the inner peripheral surface of the fitting portion 27 is equal to the original length S 1 of the flat surface. Since they are equal or longer, they are secured according to the intended setting.

造方法。1. A boss member formed in a substantially cylindrical shape having a flange on its outer circumference, and male serrations formed on a part of the outer circumference of the cylindrical shape, and an opening formed in a bottom wall of the substantially bowl shape. And a yoke having a female serration formed on the inner circumference of the fitting portion, and a boss member is provided on the fitting portion of the yoke with respect to each other. In the method for manufacturing the rotor of the magneto generator, the tip of the boss member is buckled and crimped and is fixed to the yoke, and the boss member is provided at the center of the yoke bottom wall. A step of forming an opening for insertion; and a step of bending the periphery of the opening of the bottom wall of the yoke and projecting a peripheral portion thereof inward in the axial direction of the yoke to form a substantially cylindrical fitting portion. And this mating part And the inner peripheral surface of the fitting portion, which is plastically deformed so as to be pushed back outward in the axial direction of the plug to reduce the axial length from the outer end surface of the yoke bottom wall of the fitting portion to the opening end surface. A method of manufacturing a rotor of a magneto generator, comprising: a step of forming serrations in the.
