装置。 A blow-by gas recirculation passage hole is provided, which is equipped with a check valve that vertically penetrates the piston crown and allows gas to flow to the combustion chamber side during the piston's downward stroke. A blow-by gas introduction passage hole communicates with a groove formed on the circumference of the piston between the pistons, and a container serving as a gas reservoir into which blow-by gas is introduced is arranged in the inner space of the piston skirt portion below the reflux passage hole. The upper part of the container has a cylindrical part, and the cylindrical part is connected to the reflux passage hole, while the lower part of the container is fixed inside the piston skirt part, and a small hole is formed in the bottom of the container. A piston device for an internal combustion engine, characterized in that a net-like member is disposed on the bottom of the lever.
