The present invention aims at providing a technique for providing a stepped structure separately to a rotating shaft in a later step of assembly for preventing oil leakage from a bearing box. To this end, the rotating machine of the present invention includes a rotating shaft having a rotating member, a bearing device 400 including a rotating shaft insertion hole larger in diameter than the rotating shaft 1, an oil thrower 8 provided between an outer circumferential portion of the rotating shaft insertion hole and the rotating shaft 1, and an additional ring 9 attached to the rotating shaft 1 between the oil thrower 8 and the rotating shaft 1 such as to protrude in a radial direction of the rotating shaft 1. |
