<p>A pulsar ring (7) includes an annular support member (22) having a large diameter part (25) which is provided with a flange part (26) for positioning a plurality of gear plates (23) formed of silicon steel, at a left end part thereof. A concave groove (33) in an axial direction is formed on an outer periphery of the large diameter cylindrical part (25) of the annular support member (22) of the pulsar ring (7), and convex parts (34) to be engaged with this concave groove (33) are provided on inner peripheries of the respective gear plates formed of silicon steel. After a plurality of the gear plates formed of silicon steel have been assembled, the pressure ring is assembled to the large diameter cylindrical part of the annular support member by shrinkage fit.</p> |
