PROBLEM TO BE SOLVED: To provide a cabin structure capable of restraining or preventing leakage of fluid from a flange surface by restraint of oval deformation of a cabin and/or an increase in flange bearing pressure. SOLUTION: This cabin structure is vertically divided into two parts of an upper cabin 11 and a lower cabin 12 by penetratingly inserting a rotor inside, and fastens respective divided surfaces as mutual connecting flange parts 11a and 12a by bolts, and is provided with a fluid leakage preventive means such as a peripheral directional rib 13 for preventing the fluid in the cabin from leaking to the outside by port opening of the flange surface in the mutual connecting flange parts.
