PURPOSE: A spindle motor is provided to maximize performance and life spans by preventing a position change of a stopper when the stopper is combined with a hub. CONSTITUTION: A hub(110) is interlinked with a shaft. A sleeve(120) supports the rotation of the shaft by using oil. A stopper(130) prevents the overfloating of the hub. One of facing surfaces of the stopper and the hub forms one or more press-in grooves for pressing the stopper in the hub. The other one forms one or more press-in protruding units. A press-in groove(132) is formed in the stopper. A press-in protruding unit(116) is formed in the hub.
