成したことを特徴とする内燃機関のピストン。 The oil ring fits into a piston of an internal combustion engine in which an oil passage is provided in a piston pin boss portion to guide oil scraped by an oil ring onto the sliding surface of a piston pin hole into which a connecting piston pin is inserted. An oil return hole is provided that extends inward from the bottom of the oil ring groove and passes through the piston pin boss portion, and is biased toward the side opposite to the side on which the thrust load acts. A piston for an internal combustion engine, characterized in that an oil supply hole that intersects with the oil supply hole is also biased toward a side opposite to the side on which a thrust load acts, and the oil passage is formed from the oil return hole and the oil supply hole. .
