Disclosed herein is a spindle motor. In the spindle motor according to the present invention, a thrust part is disposed at a lower portion of a shaft, and a support part surface-contacting a lower end of the shaft is formed at the thrust part so as to have a round shape, thereby making it possible to easily prevent a wobble phenomenon of a rotor due to a gap in a shaft system. In addition, a guide part is formed to be protruded at the thrust part to lock the shaft including a narrow part formed therein, thereby making it possible to easily prevent floating of the rotor. |
