Abstract: PURPOSE: A spindle motor is provided to differently form width of first and second bearing clearances corresponding to the center of gravity, thereby improving a rotation property. CONSTITUTION: A lower end of a shaft(120) is fixed to a base member(110). A thrust plate(130) is fixed to the shaft. An upper sleeve(140) forms a first bearing clearance with the shaft. A lower sleeve(150) forms a second bearing clearance with the shaft. A rotor hub(160) is rotated by connecting the upper sleeve and the lower sleeve. Width of the first and second bearing clearances is differently formed corresponding to an arrangement position of the center of gravity of a rotor(40).
