Abstract

A spindle motor comprises a housing, a hub which is rotatable relative to the housing, a rotor magnet mounted on the hub, and a stator disposed facing the rotor magnet. A coil holding member for extending a lead section of an armature coil of the stator to the outside thereof is disposed in the housing. Female screw holes into which fixing screws for mounting clamp members are screwed and through holes connecting with the female screw holes are formed in the hub. Furthermore, supporting projections extending toward the housing are disposed in the stator core of the stator, and such supporting projections are supported in the housing.
