Abstract

　　【課題】　摩擦抵抗が小さく、かつ当該摩擦特性を長期間維持することができるスカート部を有する内燃機関のピストンを提供する。 　　【解決手段】　スカート部４の摺動面に樹脂被膜層４４が形成された内燃機関のピストン１であって、スカート部は、周方向中央部に形成された薄肉部５１と、薄肉部５１の両側方にそれぞれ形成された厚肉部５２とを有し、少なくとも厚肉部における樹脂被膜層に複数の凹部４５が形成され、或いはスカート部は、ピストンの軸線方向における略中央部にて、当該ピストンの軸線からの距離を一定に維持しつつ軸線方向に延在するスカート胴部４１と、スカート胴部の下縁部から下方に延設され、下方に向かうにつれてピストンの軸線との距離が徐々に小さくなる第１縮径部４２とを有し、凹部４５は、スカート胴部と第１縮径部との境界である第１境界線６上に配列されるようにした。
