PURPOSE: A rotor for a flat vibrating motor is provided to reduce damage of the rotor, while lengthening the lifespan of the motor and reducing noises of the rotor. CONSTITUTION: A rectifier is arranged at a surface of a printed circuit board(9a), and a coil and a high gravity weight(7a) are fixed at the other surface of the printed circuit board. The coil and the high gravity weight are coupled by an insert injection of a form resin material(10a) together with an oilless bearing(60) so as to form a rotor(100). The oilless bearing has a surface on which a case contact portion(61) contacting a case, and a tapered stepped portion(62) are formed. At least a certain part of the tapered stepped portion is buried by the form resin material.
