The oil drainper-type lubrication system used in conventional general-purpose engines uses an oil drainper installed at the lower end of the connecting rod to lubricate various parts of the engine by scattering lubricating oil, but the piston and cylinder parts are separated from the oil drainer. Because of this, the amount of lubricating oil was low, causing accidents such as piston sticking and piston seizure. As a countermeasure to this problem, a method is often used in which an oil pump is installed and an oil jet is jetted toward the back surface of the piston, but this method has the disadvantage of high cost.

外周端面では小さい隙間となつている。 Further, on the side surface 7 of the web on the opposite side wall of the crankcase, which is close to the side surface of both gears 9 and 10, the guide plate 12 and both gear surfaces are gathered together.
A radial groove 11 is provided for receiving lubricating oil flowing out from around the meshing portion 15 of the piston 3 and scattering the lubricating oil in the direction of the piston 3 and the cylinder 2. Also side wall 1
The gap 16 between the gears 4 and the end faces of the gears 9 and 10 is particularly small at the outer peripheral end faces of the gears.
次に前記作用について説明する。 Next, the above-mentioned effect will be explained.

３、シリンダ２などを冷却、潤滑する。 The oil scooped up by the oil drainper 5 scatters within the crankcase 1 and lubricates the various sliding parts. Oil that directly hits the crank gear 9 and cam gear 10 and flows down from the side wall 14 and both gears 9 and 10
The oil that comes into contact with the gears moves to the meshing portion 15 of both gears due to the centrifugal force of each gear and the guide plate 12. Gear meshing part 15
Since the oil is concentrated in the crank web 7, the oil flows out in the direction of the crank web 7, adheres to the crank web 7, and then flows into the groove 11 provided in the crank web. Due to the force, it scatters in the piston 3 direction, cooling and lubricating the piston 3, cylinder 2, etc.
