Abstract

PURPOSE:To enable the deflection of a magnet protecting cover to be absorbed, by applying a waveform shape to a section pressure-applied in the axial direction of the external collar section of the magnet protecting cover. CONSTITUTION:On the inner periphery of the cylindrical section 1a of a fly- wheel 1, a magnet 4 is set in the shape of a ring. The magnet protecting cover 5 of a non-magnetic member has a collar section 5a for covering the one end surface 4a of the magnet 4 positioned at a fly-wheel opening side end section, a cylindrical section 5b for covering the inner peripheral surface of the magnet 4, and an inner collar section 5c butted to a fly-wheel bottom surface section 1b from the internal side which are integrally formed. On the peripheral edge of the external collar section 5a, a waveform shape 5d is formed. As a result, the deflection of the magnet and the magnet protecting cover generated by a load applied when the fly-wheel opening side end section is bent and rolled can be absorbed.
