ピン支持構造。 Pin holes for inserting and supporting piston pins are formed in the opposing boss portions of the piston, and a stopper surface is formed at the outer opening edge of one of the pin holes and is stepped down inward from the outer surface of the piston. At the same time, a flange with a larger diameter than the pin hole is formed at the end of the piston pin on the stopper surface side.
A piston pin support structure for a small engine, characterized in that movement of the piston pin in a direction opposite to the stopper surface is restricted by abutment of the flange against the stopper surface.
