Abstract
A rotating device includes a sleeve which encircles a shaft, a housing which supports the shaft and which forms an annular supporting recess where the lower end of the sleeve enters together with the shaft, a ring member which is provided above the sleeve and which is fixed to the shaft in a manner encircling the shaft. A first gap between the sleeve and the shaft includes first and second radial dynamic pressure generating portions. An annular sleeve recess is formed in upper face of the sleeve. The ring member includes a ring entering portion that enters the sleeve recess in a non-contact manner. An outward gap in the radial direction where the ring entering portion and the sleeve recess face with each other in the radial direction includes a second air-liquid interface of a lubricant.
