PROBLEM TO BE SOLVED: To provide a fluid machine capable of achieving further miniaturization and the reduction of the weight of a hydraulic machine while improving reliability relating to the lubricating performance of the fluid machine by a simple mechanism. SOLUTION: The fluid machine is provided with a rotary shaft 12 extending in a body 3 of a hermetic vessel 2 and rotatably supported via bearings 12, 28, a motor driving the rotary shaft by electricity supply and including a rotor 7 and a stator 8, a scroll unit 30 held at the upper side of the motor, a frame member 14 supporting the rotary shaft via the bearing, and a flow direction regulating means 80 regulating the direction of lubricating oil flowing down from a scroll unit side to a motor side to prevent lubricating oil supplied to the bearing from an oil storage chamber 23 from flowing into a stator side. The flow direction regulating means includes a guide member 82 fixed on the upper surface 7a of the rotor and leading the flowing-down lubricating oil to the upper surface, and a discharge path orienting the lubricating oil led to the upper surface toward the oil storage chamber.
