To provide a fluid machine capable of enhancing lubricity, and improving reliability.

The fluid machine includes: a lubricating mechanism (70, 72) supplying lubricating oil stored in an inner bottom part (2a) to the upper part of a sealed container (2) by a rotary shaft (14); a frame (36) fixed to the sealed container, supporting a driven unit (6) by being brought into contact with an upper face (16a) of a cylinder block (16), and in which the lubricating oil supplied to the upper part of the sealed container flows down a top face (38a); a connecting rod (20) disposed on the lower side of the frame, and connecting the rotary shaft to a piston (18); a piston pin (66) connecting the connecting rod to the piston; a first oil supply hole (78) formed by penetrating the frame and the cylinder block; and a second oil supply hole (80) formed by penetrating the frame.
