PURPOSE: A spindle motor is provided to reduce the height deviation of height by simultaneously compressing a part of a rotary shaft and bonding the compressed part to a rotor yoke using an adhesive. CONSTITUTION: A rotary shaft(132) is pivotally inserted into the center part of a stator. A rotor assembly includes a rotor yoke and a magnet including a combination pipe(151) into which the rotary shaft is inserted. The magnet is combined with the inner circumference of the rotor yoke to be opposite with the stator. The rotor assembly and the stator rotate. The combination pipe includes a compressing part(152) and a bonding part(153). |
