Claim:
A spindle motor comprising: a base; a bearing housing supported on the base; a bearing provided within the bearing housing; a rotating shaft rotatably supported by the bearing; a stator including a core fixed to the bearing housing and coils wound around the core; a rotor including a rotor yoke fixed to the rotating shaft, and a first magnet installed on the rotor yoke facing the stator; a turntable positioned on the rotor yoke, rotating together with the rotating shaft; a center guide member coupled to the rotating shaft at an upper side of the turntable; an elastic member disposed between the turntable and the center guide member for elastically supporting the center guide member, wherein the center guide member comprises: a plate into which the rotating shaft is inserted, to be capable of rising and descending; a wall formed to extend upward from an outer circumference of the plate; and a band formed to extend downward from the wall, wherein a first portion of the plate adjacent to the rotating shaft is thicker than a second portion of the plate adjacent to the wall, wherein the turntable includes: a first upper surface adjacent to the rotating shaft, a first wall directly connected to the first upper surface and extended upward, a second upper surface directly connected to the first wall and extended upward, and a second wall directly connected to the second upper surface and extended upward, wherein a lower end of the elastic member is directly in contact with at least one of the second upper surface and the second wall.
