Abstract

PURPOSE:To make a lubrication of the bearing smoothly operable with a misfiring prevented as well, by such construction to lead a lubricant oil component, easy to stand still in the crankchamber, into the bearing of the crankshaft. CONSTITUTION:In bottom surfaces of each crankchamber 8 is provided a labyrinth seal 16, on top of which a guide groove 22 is constructed. Consequently, the fuel component, especially lubricating oil component, accumulated in the bottom surfaces of the crankchamber 8, flows into the above guide groove 22. And because said guide groove 22 becomes deeper gradually toward the direction of rotation of a crankshaft 5, the lubricating oil in the guide groove 22 flows in toward a small hole 23 by guidance of rotation of a crankarm 9 following a rotation of the crankshaft 5. The lubricating oil, coming to reach the small hole, passes through a check valve 24 flowing to lower surface, dropping into bearings 15b, 15c. Consequently, the fuel oil and lubricating oil, that are easy to stand still in the crank-chamber 8, will be removed from the crankchamber.
