PROBLEM TO BE SOLVED: To provide a bearing device capable of achieving low speed rotation to high speed rotation, and performing stable performance for a long period even when applied to a rotary body to which high loads are added. SOLUTION: In this bearing device, a spool shaft 5 is rotatably supported on a support part 7. Between the spool shaft 5 and the support part 7, a rolling bearing 21, and a fluid bearing 27 to support the spool shaft 5 by dynamic pressure generated by high speed rotation of a groove 28 are juxtaposed in a diametric direction.
