ABSTRACT:
A metallic gasket including a base plate having a convex metal bead formed, by bending the base plate, between a combustion chamber opening and on the outer periphery portion of the base plate, and a first thickness-increased portion formed thicker than the remaining portions of the base plate to provide a difference in thickness, by which a surface pressure is made to concentrate on the first thickness-increased portion to seal a joint between a cylinder head and a cylinder block when the metallic gasket is disposed between the joint surfaces of the cylinder head and the cylinder block and fastened by clamping bolts. An elastic sealing material is fixed to the convex portion of the metal bead and filled in a concave portion on the reverse side of the base plate to form a rubber bead, and the sealing material is deformed under compression in the through-thickness direction in cooperation with the deformation of the metal bead when the gasket is fastened with clamping bolts. This gasket reduces production cost and preserves a stable sealing performance for extended periods of time.
