PROBLEM TO BE SOLVED: To provide a gasket which can secure a sufficient sealing capability even for compact, light and less rigid high-performance engines. SOLUTION: The gasket comprises a metallic base plate 1 and a shim plate 4 stacked around each of combustion chamber holes 2 in the base plate 1. A base plate bead 3 is formed on the base plate 1 along the circumference of each of the combustion chamber holes 2. The shim plate 4 is large enough to be arranged opposite to a first flat part B1, a base plate bead formation position A and a second flat part B2 in the base plate 1. A plurality of strips of auxiliary beads 5a are formed in the part of the shim plate 4 opposite to the base plate 1. COPYRIGHT: (C)2007,JPO&INPIT
