PROBLEM TO BE SOLVED: To enhance the reliability of a scroll fluid machine by preventing foreign matters such as a fluid leaking into a crank chamber from a compression chamber and water mixed with the fluid and entering therein from entering a rolling bearing arranged in the crank chamber, and preventing the lifetime of a rolling bearing from being shortened. SOLUTION: A hole is opened, which is communicated with an external space from a space formed of a fixed frame, and a spacer, a turning scroll and a fixed scroll. Even when a fluid leaking from a compression chamber leaks into a space containing a bearing of a crank or a three-point crank, the fluid is not passed through the inside of the bearing but discharged into the external space through the hole communicated with the external space, and the reliability can be enhanced.
