Zusammenfassung:	A spindle motor is provided to prevent a rotation axis and a rotor from floating by firmly fixing a stopper in a bearing. One side of a bearing housing(120) is opened. A first bearing is fixed in an inner circumference of one side of the bearing housing. A second bearing(135) is inserted into an inner circumference of the other side of the bearing housing. A rotation axis(140) is rotatably supported in the first and second bearings. A stator(150) is arranged around the bearing housing. A rotor(160) rotates the rotation axis by interaction with the stator. A stopper(180) is fixed to the first bearing in order to prevent the flotation of the rotation axis to one side of the bearing housing. An elastic member is arranged between the second bearing and the other side of the bearing housing. The elastic member supports the rotation axis to one side of the bearing housing elastically.
