<p>PURPOSE:To reduce the diameter of a clutch rotor and to improve durability, by forming the clutch rotor of an external and internal cylindrical parts and a non-magnetic material filled so as to connect the external and internal cylindrical parts with each other. CONSTITUTION:A clutch rotor is formed of external and internal cylindrical parts 111, 112 and a non-magnetic material 113 filled so as to connect the external and internal cylindrical parts with each other. With this construction, the diameter of the clutch rotor can be reduced as a flow of a flux is made mainly into a route surrounding a bearing 2 and the thickness of internal cylindrical part 112 can be reduced as thin as possible. In addition to the above, durability of the clutch rotor can be improved as the tension of a belt to be applied to the external cylindrical part 111 is received by a vast area.</p> |
