陥を除去した単体形ガスケットを提供することを目的と
して案出したものである。[Detailed description of the invention] Metal veneer gaskets for internal combustion engines are considered to be unsuitable for sealing holes in liquids such as water and oil, but the present invention aims to provide a single-piece gasket that eliminates this defect. It was devised for this purpose.

基板１の板厚とをほぼ均一にして構成したものである。The drawing shows an embodiment of the metal veneer gasket for internal combustion engines according to the present invention, 1 is a gasket substrate, and the substrate 1 is formed by press-forming a single iron plate, and has holes for liquid such as water. For installation of thin walls, cut out both the front and back sides along the periphery of 2.
The seal ring 4 is fitted into the liquid hole 2 by sandwiching the piece 5, and the seal ring 4 is made by bending a metal plate and coating the surface with a heat-resistant plastic film 6 such as urethane resin. An annular body 7, which is provided with cushioning properties by bending a steel plate into a Z-shaped cross section, is sandwiched between the annular bodies 7 and the plate thickness of the clamping portion 8 and the plate thickness of the substrate 1 are made almost uniform. be.

である。Since the present invention has the above-mentioned structure, it is possible to eliminate the non-sealing property of the liquid hole in this type of gasket, and it is also possible to create an annular body in which a metal plate is bent into a Z-shaped cross section to provide cushioning properties. Since it is installed inside the seal ring, due to the structure of the annular body, the surface of the seal ring is in surface contact with the cylinder head and the body, and moreover, it follows the vibrations and expansion and contraction caused by engine operation. Sealing can be performed even more reliably, and
The thin-walled seal ring is installed by sandwiching the piece and fitting it into the liquid hole, which prevents it from falling off and is convenient for transportation.Tightening the seal ring prevents the load from concentrating on the surface of the seal ring and allows it to fit into the liquid hole. There is no risk of impairing the sealing performance of the hole.
