Abstract

There is provided a piston for an engine that makes it possible to improve supply of engine oil to a recessed part as a result of diligent studies on a piston coated with a resin coating film. A piston for an engine includes a resin coating film 2 and a recessed part 3 on a surface 1a of a skirt part 1. In the piston, resin coating films 2a are distributed in a patchy fashion on the surface 1a of the skirt part 1, and the recessed part 3 formed by the surface 1a of the skirt part 1 between adjacent ones of the patchy resin coating films 2a and by the adjacent resin coating films 2a and 2a constitute a net-like groove 4, and an outer-edge resin coating film 2b extending in a piston movement direction 6 is provided at ends, in a piston circumferential direction, of the skirt part 1.
