Abstract
A rotor in a magnetogenerator, having a boss member coupled onto a rotary shaft of an engine and a yoke jointed to a flange on the outer periphery of this boss member. A serration provided at one end thereof with a collar portion is formed on the outer periphery of the flange of the boss member. Another serration is formed on the inner peripheral surface of an opening formed in the bottom wall of the yoke, and both serrations are serration-jointed to each other by clinchingly finishing an end portion of the flange received in a recess formed at an end face of the opening in the yoke, whereby the brim, or lip, portion of the opening in the yoke is clamped between the collar portion and the clinchingly finished portion. The collar portion of the boss member, thus serration-jointed, is received in the recess formed around the brim portion of the opening in the yoke, to prevent the collar portion from protruding to the outside from the bottom wall surface of the yoke in the axial direction.
