PURPOSE: To facilitate the continuous operation of a degasser for a long time by providing outlet and inlet ports to be communicated with a lubricant container in a gear box installed between a drive shaft and an output shaft so that the lubricant flows in/flows out by the same quantity in an interlocking manner with the operation of the drive shaft. CONSTITUTION: A drive shaft 36 is connected to an output shaft 77 through a gear box 40 with a gear device such as a planetary gear built therein. An outlet port 46 and an inlet port 50 are provided in the gear box 40 to communicate a container 200 to store a liquid hydrocarbon lubricant, etc., with pipes 216, 218. The pulse of the lubricant is supplied in an interlocking manner with the operation of the drive shaft 36 from the outlet port 46 of the gear box to the container 200, and the pulse of the lubricant of the same quantity is returned to the gear box 40 from the inlet port 50. The gears in the gear box 40 are appropriately lubricated, and the device can be continuously operated for a long time.
