Abstract: In a rotor of a micro motor, a magnet is indirectly attached to a rotor shaft by means of a pair of bushes without using any adhesive material. The pair of bushes comprises upper and lower bushes which are respectively mounted by means of an interference fit around the rotor shaft. Each bush comprises a cylindrical portion in the center of which a hole is formed, and a flange portion having around its periphery an annular notched portion. The notched portion of the upper bush is formed on a lower surface of the flange portion adjacent to the outer periphery of the cylindrical portion while the annular notched portion of the lower bush is formed on an upper surface of the flange portion adjacent to the outer periphery of the cylindrical portion, and due to the notched portions, each flange portion is provided with a certain degree of resiliency.
