Provided is a fluid dynamic bearing device, which fixes a lid member (10) to a bracket (6) or forms the lid member (10) and the bracket (6) integrally so that the bracket (6) exerts the release resistance of the lid member (10). As a result, the fluid dynamic bearing device can alleviate a fixing force required between a housing (7) and the lid member (10) or can make their fixture unnecessary, to thereby maintain the release resistance of the lid member (10) irrespective of a material of the housing (7). |
