Abstract
In a spindle device mounted to a disc driving apparatus, a mist seal which blocks a mist of lubricating fluid, an oil seal which prevents the lubricating fluid from flowing out, and an oil pool which prevents surplus fluid from flowing out, are combined and disposed so that the lubricating fluid from a dynamic-pressure-fluid bearing is prevented from flowing out or splashing into a clean space. As a result, inconveniences such as a head crush or a head absorption can be avoided, and a reliable spindle device is realized.
