Abstract

PURPOSE:To enable the formation of an accurate pole capable of preventing the increase in the outer diameter of a flywheel simply by forming and shaping a projection which is projected form an annular groove at a part of a thin bottom of the annular groove formed at a part of the side of a cup-shaped flywheel. CONSTITUTION:A coil 10 is wound on a core 9 having a magnet 11 to form a generating element 8, and the core 9 is faced with a pole 2 formed at a part in the annular groove 1a at the outer periphery of a cup-shaped flywheel 1 upon rotation of the flywheel 1. An annular groove 1a being smaller than the outer diameter of the side over the entire periphery and a thin part 3b at the inner peripheral side are cut at the part of the side 3 of the flywheel 1, and a projection 3a projected toward the outer peripheral side of the groove 1a are respectively formed at the side 3 of the flywheel 1 and at the part of the thin part 3b using a punch, a die, and a blank holder. Then, the tools are replaced with a punch 18, a die 16, blank holders 15, 17, thereby the projection 3a is shaped, and a pole 2 disposed at the groove 1a is formed.
