オイルリング溝との間のランド外周面に環状凹部
を形成するようにしたエンジン用ピストンにおい
て、該外周面の該オイルリング溝側の外径に比し
該圧縮リング溝側の外径が小さくなるよう該凹部
に該圧縮リング溝に連続して形成したことを特徴
とするエンジン用ピストン。 In an engine piston in which an annular recess is formed on the outer peripheral surface of a land between a compression ring groove and an oil ring groove formed on the piston body, the diameter of the piston is smaller than the outer diameter of the outer peripheral surface on the oil ring groove side. A piston for an engine, characterized in that the recess is formed continuously with the compression ring groove so that the outer diameter on the side of the compression ring groove is small.
