Claims

[Claims for Utility Model Registration] A gasket structure for an engine comprising a metal gasket interposed between a first joint surface of a cylinder block and a second joint surface of a cylinder head, the gasket structure comprising: said metal gasket; In order to form a gasket made of a base-side metal plate that is pressed against the first joint surface and a head-side metal plate that is pressed against the second joint surface, a folded portion is formed on the head-side metal plate. A gasket structure for an engine, characterized in that the gasket structure is constructed by sandwiching a part of the base side metal plate, and a friction reducing layer is formed on a surface of the head side metal plate in contact with a cylinder head.
