ROTOR FOR MAGNETO GENERATOR

PURPOSE:To effectively fix a magnet protecting member to the bottom of an iron cup by absorbing an irregularity of sizes of parts by the deformation of a swelled portion of a cylindrical portion of the member. CONSTITUTION:An irregularity of sizes of parts is absorbed by radially outward deformation of a swelled portion 5h of a cylindrical portion 5a of a magnet protecting member 5. Since the size of the outer diameter of the cylindrical portion 5a of the member 5 at its bottom side is reduced by the size of the inner diameter of an array of magnets 4 at this time, the stationary portion 5b of the member 5 is less deformed. Accordingly, the member 5 can be effectively fixed to the bottom of the iron cup 1. Since the center of both axial ends of the magnet 4 is formed lower than the both sides, the both end sides of the magnet 4 at axial ends are contacted with the cup 1, and the magnet 4 can be disposed in the cup 1 without inclining.
