Claims

[Claims for Utility Model Registration] A piston 3 is slidably fitted into a cylinder 2 of an engine 1, and a piston pin 4 of the piston 3 and a crank pin 6 of a crankshaft 5 are interlocked and connected by a connecting rod 7. An oil spoon 9 extends downward from the lower part of the large end 8 of
In an engine splash type lubrication device configured to splash oil into the engine, an oil splashing protrusion 12 is provided protruding from a shoulder portion 8a on the oil splashing side of the large end 8 of the connecting rod 7, This splash-type lubricating device for an engine is characterized in that the oil-splashing protrusion 12 is configured to splash a part of the scattered oil in the crank chamber 10 onto the inner wall surface of the piston 3.
