Claims

[Scope of Claim for Utility Model Registration] (1) In a flywheel magnet rotor in which magnets are attached to the inner periphery of the peripheral wall of a cup-shaped flywheel, the inner periphery of the peripheral wall of the flywheel near the bottom wall. A groove continuous in the circumferential direction is formed at the position, a magnet positioning member made of an elastic annular body formed in a substantially ring shape is fitted and held in the groove, and the magnet positioning member is arranged on an axial end surface of the magnet. 1. A flywheel magnet rotor comprising an axial positioning section that receives the magnet and positions the magnet in the axial direction of the flywheel. (2) The flywheel magnet rotor according to claim 1, wherein a reluctor that constitutes a rotor magnetic pole of a signal generator is formed on the outer periphery of the flywheel.
