Abstract
In an aerodynamic bearing, an outer peripheral surface of a shaft and an inner peripheral surface of a sleeve face each other in a radial direction. The sleeve includes a through hole penetrating the sleeve in the radial direction. A space on a radially inner side of the sleeve communicates with an external space of a motor through the through hole. A stationary portion includes a wall portion radially overlapping the through hole with a gap interposed therebetween on a radially outer side of the through hole.
