In the two-stroke engine connected by the crankcase, an oil passage for supplying engine oil is formed in the crankcase,
This oil passage is branched and extended to each of the plurality of crank bearings, and the oil passage is branched into the oil passage in the crankcase opposite to the rotation locus of the large end of the connecting rod connected to the crankshaft. A lubrication structure for a two-stroke engine, characterized in that an oil spout is formed in the lubrication structure. *Figure Figure 1 is a cross-sectional view of the main parts of a 2-stroke engine to which an embodiment of the 2-stroke engine lubrication structure according to this invention is applied, and Figure 2 is a 2-cycle diagram showing the lubrication structure of a conventional 2-stroke engine.
