This vehicle mechanical component includes a mechanical component body, a heat insulating layer formed on the mechanical component body, and a protective layer formed on the heat insulating layer and including an inorganic compound that includes an alkoxide and scale-like inorganic solid particles dispersed in the inorganic compound.

Vehicle mechanical component and piston

Any one or more members of an engine, that is, a piston, a cylinder head and a valve, has a wall face disposed face-to-face to a combustion chamber, and the wall face is coated by a heat-insulation coating film. The heat-insulation coating film includes a heat-insulative layer formed on a surface of the wall face, and an inorganic-system coated-film layer formed on a surface of the heat-insulative layer. The heat-insulative layer includes a resin, and first hollow particles buried inside the resin and exhibiting an average particle diameter being smaller than a thickness of the heat-insulative layer. The inorganic-system coated-film layer includes an inorganic compound.
