PROBLEM TO BE SOLVED: To provide a turbomachine capable of improving heat dissipation of a second bearing.SOLUTION: A turbomachine 10 comprises a first bearing 20 supporting a region of a shaft Ma nearby an impeller 17, and a second bearing 30 supporting a region farther away from the impeller 17 than the first bearing 20. The turbomachine 10 comprises a disc spring 41 placing a load on the second bearing 30 and a second bearing case 31 assembled in a housing 11 with the second bearing 30 accommodated. The second bearing case 31 has a second cylinder part 31a in which a second outer ring 33 of the second bearing 30 is pressed and a second flange 31b shaped to project outward from an outer peripheral surface of the second cylinder part 31a. The disc spring 41 has a first abutting part 41b abutting on a second flange 31b at one axial end, and a second abutting part 41c abutting on an inner surface of a cover 19 at the other axial end.SELECTED DRAWING: Figure 1 |
