ABSTRACT:
A gasket of the invention is formed of a gasket member extending substantially throughout an entire area to be sealed. The gasket member includes a base metal plate and at least one sealing member disposed on at least one of surfaces of the base metal plate. A sealing section and a pressure affecting portion are formed in the sealing member. The sealing section has a compressibility, while the pressure affecting portion has a height and compressibility less than those of the sealing section. When the gasket is tightened, the sealing section is compressed to securely seal around a hole to be sealed. The pressure affecting portion having less compressibility is formed near bolt holes, so that the gasket can be tightened easily without gradually decreasing its tightening pressure.
