トンピン支持構造。 Pin holes for inserting and supporting piston pins are formed in the opposing boss portions of the piston, respectively, and at least one of the two pin holes has an outer opening edge that is lowered inward than the outer surface of the piston. A stopper surface is formed, and the end of the piston pin protrudes beyond the stopper surface toward the outer surface of the piston, and a circumferential fitting groove is formed on the outer periphery of the protruding end of the piston pin. A piston pin support structure for a small engine, characterized in that a snap spring that comes into contact with the stopper surface is fitted in the groove.
