摘要： A turntable-integrated spindle motor according to the present invention is constituted by a stator and a rotor. The rotor is constituted by a shaft 4 supported in a bearing in a cantilever support manner, a metallic rotor case 1 fixed to the shaft 4 by a boss 3, and a magnet 10 fixed to an inner circumferential surface of the rotor case 1. A plurality of projections 2 are formed integrally with the metallic rotor case so as to project from the side surface of the metallic rotor case, the projections being arranged along one circumferential line. The projections 2 perform a coming-off-prevention function by engaging with an engaging portion of a chassis 15. The rotor case 1 also functions as a turntable. In the present invention, the motor and the turntable are combined integrally with each other to obtain improved characteristics as well as to reduce the overall height. Also, projections for preventing coming off are formed integrally with the metallic rotor case to ensure high strength of the projections.
