PURPOSE: A spindle motor is provided to reduce vibration and noise through a pulling plate in which a concave unit and a convex unit. CONSTITUTION: A stator core(150) is fixed in a base member(10). A coil(101) is wound around the stator core. A driving magnet(146) is installed at a rotor hub(140) in order to face to a front end of the stator core. A pulling plate(160) is installed in a base member in order to be arranged at a lower part of the driving magnet. A convex unit and a concave unit are formed on the pulling plate.
