A spindle motor is provided to make the assembling process convenient by uniting the axis of rotation with the rotor york after the suction magnet is pressed into the rotation axis. The bearing(130) dipping with the oil is fixed inside the bearing housing(120). The axis of rotation(140) is pivotally supported in the bearing. The stator(150) is arranged around of the bearing housing. The rotor(160) acting with the stator is fixed to the site of the rotation axis exposed by the outer side of the bearing housing. The suction magnet(180) is fixed to the rotation axis part between the rotor and the bearing housing. The projection plate is located in the inner side of the bearing housing. The suction magnet is made of the ferrite of the rubber material.
