Provided are: an oil supply component for a screw exhaust pump, which makes it possible to realize a screw exhaust pump that can operate without maintenance over a long period of time and from a low-speed rotation range to a high-speed rotation range; and a screw exhaust pump provided with this component. The pump has a helical structural body disposed inside a rotating shaft of the pump, the helical structural body being capable of exhibiting a liquid-pumping function, and the structural body is configured from a driveable helical structural body positioned below the rotating shaft and a fixed helical structural body positioned thereabove. |
