Flat type vibration motor

A flat type vibration motor, comprising:

• a bracket having a shaft mounted to a central portion of the bracket, with a lower substrate and a magnet being adhered to an upper surface of the bracket;
• a casing covering an upper portion of the bracket, and defining an internal space;
• an upper substrate having on a lower surface thereof a commutator and having a through hole;
• a coil and a weight adhered to an upper surface of the upper substrate;
• a resin member provided on some portion of the upper substrate where the coil and the weight are not adhered and having a bearing holding hole;
• a bearing held in the bearing holding hole, and rotatably supported by the shaft;
• and
• a brush secured at a first end thereof to the lower substrate, and contacting at a second end thereof to the commutator to form a contact part,
• wherein the resin member is injection molded integrally with the upper substrate, or the resin member is manufactured through injection molding, and is secured to the upper substrate through force-fitting, and the resin member is formed around a region into which the bearing is inserted to have the bearing holding hole, and the coil and the weight are not surrounded with resin.
