A turbo machine includes an impeller that rotates to make gas flow, a driving device that rotationally drives the impeller, a rotary shaft that transmits a rotational driving force of the driving device to the impeller, a bearing that rotatably supports the rotary shaft, and a casing that houses at least the driving device and the rotary shaft. In addition, the casing is provided with a grease flow path to supply grease to the bearing for lubricating the bearing. |
