A spindle motor capable of preventing deformation of felt is provided to prevent separation of a felt by forming a support groove or a support protrusion on a turntable. A spindle motor comprises a rotation shaft(130), a stator(140), a rotor(150), a turntable(160), a felt(190), and a support protrusion. The rotation shaft is pivotally installed in a base(120). The stator is fixed near the rotation shaft. The rotor is fixed in the rotation shaft, and is rotated by interaction with the stator. The turntable is fixed in the rotation shaft. A disk(50) is mounted on the turntable. The felt is installed in the turntable, and supports the disk. The support protrusion is formed in the turntable. An outer circumference of the felt is contacted in the support protrusion. The support protrusion prevents deformation of the felt.
