A gasket structure of a cylinder head for an automobile is provided to prevent coating deterioration and leakage of combustion gas due to opening of upper and lower plates of a bead plate by forming the upper and lower plates of the bead plate in a contact structure. A gasket structure of a cylinder head for an automobile includes a cylinder block(200), a cylinder head, a plurality of cooling water holes(110), a plurality of oil holes(120), a plurality of bore holes(130). The cooling water and oil holes are formed on a cylinder head gasket(10) to connect an oil passage and a cooling water passage formed on the cylinder block and the cylinder head. The bore holes are formed on the cylinder head gasket to be connected to a cylinder bore formed in a combustion chamber of the cylinder block. The cylinder head gasket is made of steel material to withstand high temperature and high pressure. A bead plate is installed at the cylinder head gasket to seal cooling water and oil. The gasket structure is set as a closed structure to be close in contact with a core plate to face each other in an inside direction by bending left and right side ends of top and bottom plates. |
