Abstract: A bearing structure includes a rotating shaft, a thrust collar, and a first thrust bearing. The rotating shaft has a central axis. The thrust collar is mounted on the rotating shaft. The first thrust bearing includes a first dynamic pressure generating mechanism. The first dynamic pressure generating mechanism faces the thrust collar. The relation Rt>Rf1 is satisfied, where Rt represents a length from the central axis to the outer circumferential edge of the thrust collar, and Rf1 represents a length from the central axis to the outer circumferential edge of the first dynamic pressure generating mechanism.
