トン装置。 A piston land portion including a piston top surface and a ring groove and a piston skirt portion are formed separately, and the piston land portion and piston skirt portion are formed by hollow piston pins inserted into respective piston pin holes. In a piston device for an internal combustion engine in which the pistons are connected to each other and are rotatably connected to a connecting rod, an oil passage is provided that extends longitudinally through the connecting rod toward the piston pin, and the piston pin has a connection between the oil passage and the piston pin. An oil introduction hole that communicates with the hollow part and an oil supply hole that communicates between the hollow part and the piston pin hole of the piston land part are provided, and the piston land part has an oil introduction hole that communicates with the piston pin hole of the piston land part. A piston device for an internal combustion engine, characterized in that an oil drain passage is provided that communicates between the piston pin hole and the outside of the piston pin hole.
