A fluid dynamic bearing apparatus with an increased adhesive strength between a component having an adhesion fixing face and a bracket is provided by appropriately controlling the adhesion gap. Materials for a bracket and a housing are selected so that the value obtained by dividing the linear expansion coefficient of the housing fixed to the inner periphery of the bracket by the linear expansion coefficient of the bracket having a portion for mounting a stator coil of a motor is not lower than 0.5 but not higher than 2.0. An adhesion fixing face formed on the outer periphery of the housing is adhesively fixed to the inner circumferential surface of the bracket with an anaerobic adhesive or an epoxy-based adhesive.
