Abstract

PURPOSE:To increase rigidity to the twist of a rotary rim, and to obtain mechanical strength sufficient to revolving torque by positioning a rim key matching in the circumferential direction between each adjacent magnetic plate of the rotary rim. CONSTITUTION:Key ways 14 are formed among each adjacent magnetic plate 13 of the rotary rim 3, which is fixed onto a spider 2 through a key 5 and shaped by laminating the magnetic plates, while crossing both magnetic plates. The rim keys 15 are fitted to the key ways 14, and the displaycement in the circumferential direction and diametrical direction of the adjacent magnetic plates 13 is prevented. The rim keys 15 extend in the diametrical direction in the vicinity of the inner circumferential side of the rotary rim 3, and are shaped cylindrically.
