固定したことを特徴とする内燃機関のピストン。The lower wall of the hollow part formed on the back surface of the top of the piston is composed of a plate separate from the piston main body, and shelves are protruded from the inner surface of the piston main body into the hollow part on both sides of the bin post part on both sides of the hollow part. In a piston for an internal combustion engine in which the shelf has a slit extending from the oil ring groove to the hollow part, a flat part extending along both sides of the pin boss part of the plate is brought into contact with the lower end of the shelf from below. , in the plate portions adjacent to each of the planar portions, a curved portion is formed which extends upward from the plate end and whose upper end is bent outward, and the upper end of the curved portion is connected to the slit portion of the shelf. A piston for an internal combustion engine, characterized in that the plate is fixed to the piston body by being fitted into the piston body, and the shelf portions on both sides of the pin boss portion are sandwiched between the flat portion and the upper end of the cursive portion.
