PURPOSE:To effectively mount a rotor element on a rotational shaft by forming a taper to be engaged with each terminal face of a boss to be engaged with a shaft of the rotor element, and further forming a shoulder having a taper on the shaft of the rotor element. CONSTITUTION:A shoulder 24 is formed at a position to be engaged with a rotor element 18 disposed at one end side at a rotational shaft 12, and a taper 26 directed outward is formed at the shoulder 24. A nut 28 is clamped to engage a wedge between the taper 25 of the shoulder 24 and make taper 18d and female taper 18e formed on the ends of the projecting cylinder of a support 18a for forming a boss, and a nut 28 is clamped to provide a suitable torque, thereby setting each rotor element 18 at the suitable axial position. |
