Abstract:
The present invention provides a metal gasket to be fitted between a cylinder head and a cylinder block to seal a gap between the surfaces thereof, which comprises: a thin metal plate with an opening formed at a position corresponding to a bore portion of the cylinder block, the opening having a diameter larger than that of the bore portion; and a pair of elastic metal substrates each having: an opening which substantially agrees with the bore portion of the cylinder block; an annular convex portion formed concentrically with the opening at a position apart from an edge portion of the opening by a specified distance; and an annular holding portion for holding a peripheral portion of the opening of the thin metal plate, horizontally extending out from an outer edge portion of the convex portion, wherein the pair of the elastic metal substrates are disposed so that top portions of the respective convex portions face each other and that the holding portions overlap with the thin metal plate, and engaged to the thin metal plate at a plurality of positions.
