Abstract
A cylinder head device for an internal combustion engine has a cylinder head with a mounting hole in which a fuel injector is inserted and a ring-shaped metal gasket. The mounting hole has an annular seat surface for supporting the fuel injector therein. The metal gasket is sandwiched between the fuel injector and the seat surface. The metal gasket includes a core and a coating layer for covering the entire surface of the core. The core has a contour approximately formed in the shape of a truncated cone in section, and also has inner and outer circumferential edges curved in an arc shape.
