Abstract

A piston for an internal combustion engine capable of reducing a sliding friction of the piston by lubrication oil, in the case where a load exerted in an axial direction of the piston is small. In a piston 7 of an engine 1, a skirt portion 13 has a central skirt portion 13A on which a central resin coating layer 21A is formed and in which a central portion in an axial direction O of a piston crown portion 9 has a maximum outer diameter, an upper skirt portion 13B on which an upper resin coating layer 21B is formed and in which an upper side than an upper boundary 13a of the central skirt portion 13A is curved such that an outer diameter becomes gradually smaller from the central skirt portion 13A toward the axial direction O, and a lower skirt portion 13C on which a lower resin coating layer 21C is formed and in which a lower side than a lower boundary 13b of the central skirt portion 13A is curved such that the outer diameter becomes gradually smaller from the central skirt portion 13A toward the axial direction O, and the resin coating layer 21 is such that a surface of the central resin coating layer 21A is formed as a smooth surface, and concave portions 22 and 23 for retaining oil are formed on the upper resin coating layer 21B and the lower resin coating layer 21C.
