PURPOSE: To provide an inexpensive structure of rotors which shows a good material yield, and good assembling workability.
CONSTITUTION: An inner ring 4 having a roughly C-like cross section is fitted inside main body 3 of the ring-shaped rotor having many holes 2 formed at an equal pitch. A flange part 6 is formed at bent to project outward at either end part of the inner ring 4. The rotor 1 is pressed and fixed into a counterpart hub 8. At this time, an inner peripheral surface of the inner ring 4 is a pressure contact face. When the inner ring 4 is fitted to the rotor main body 3, the inner ring 4 is meshed with the inner side of the rotor main body 3 while the inner ring 4 is elastically deformed in a direction to reduce the diameter, and outer peripheral surface of the inner ring 4 is brought into press-contact with an inner peripheral surface of the rotor main body 3.
