Abstract
A spindle motor is disclosed which is configured such a manner that a rotor is press-fitted into a portion of a rotor fastener corresponding to a radially thicker portion out of outer portions of the rotor fastener of a clamping device, and a portion of the rotor fastener corresponding to a relatively thinner radial portion is filled up with an adhesive to adhesively couple a case with the rotation shaft side. Consequently, even if the rotation shaft side is coupled with the case, the case is not damaged to therefore enhance the reliability of the product.
