Abstract
PURPOSE: To device to lubricate even under a small oil pressure by the work of centrifugal force by arranging the lubricating oil passage in a crank shaft to avoid the central axia of rotation of the crank shaft.
CONSTITUTION: A lubricating oil entrance 13 to face to an annular groove 71 in a bearing part 6 of a crank case 1 is provided on the surface of a crank main shaft 9. A lubricating oil exit 17 is provided on the surface of a crank pin 10. These lubricating oil entrance 13 and exit 17 are connected by a connecting passage 15 in a crank shaft 8 to feed lubricating oil into the above-written annular groove 71 with pressure for lubrication. This passage 15 is arranged to avoid the rotation center 0-0 of the crank shaft 8. Consequntly, the lubricating oil is lightened to resist the centrifugal force, and able to circulate even in a smaller pressure by the lightened portion.
