Abstract

PURPOSE:To elminate waste of lubricating oil and to smooth feed of the oil by providing a communication room, which is in communication with an empty room installed in the middle of shaft and which has small holes in its inside, and a communication hole which is to put the abovementioned empty room in communication with the crank room. CONSTITUTION:Centrifugal force generated by rotation of the crank shaft 1 will separates the lubricating oil in an oil hole 5 into the lubricant proper and bubbles according to the specific gravity, where the lubricant with larger specific gravity are led to the internal wall of the oil hole 5 and bubbles with smaller specific gravity are led to the central area. Accordingly, the opening of oil supply hole 10 on its oil hole 5 side is filled with the lubricating oil at all times even though bubbles are generated in the oil hole 5, so that there is not risk of too short feed of lubricating oil. The bubbles staying in the central part of the oil hole 5 are led into the empty room 15 through a small hole 17 furnished in a communication pipe 16 and further exhausted to the crank room 13 through a communication hole 18, so that the lubricating oil can flow smoothly in the oil hole 5.
