Claims

[Scope of utility model registration request]

In an exhaust manifold gasket interposed between a cylinder head and an exhaust manifold of a multi-cylinder internal combustion engine, the exhaust manifold gasket is composed of a gasket having a laminated structure, and a portion corresponding to the central cylinder is provided in the middle layer of the lamination. Plates with different coefficients of thermal expansion are arranged for parts corresponding to the outer cylinder, and the coefficient of thermal expansion of the plate provided in the part corresponding to the central cylinder is equal to the coefficient of thermal expansion of the plate provided in the part corresponding to the outer cylinder. The exhaust manifold gasket is characterized by being larger.
