Abstract
A spindle motor comprises a central axis fixed to a housing base. A core body is cantilevered by an annular member so as to support a coil of a stator. The coil is fixed to the housing base by an adhesion. The cantilevered core body is also supported by the housing base, so that the movement of the core body and coil is reliably restrained. The stator is prevented from vibrating during rotation of the rotor. Accordingly, reduction in the vibration of the spindle motor can be achieved.
