Abstract
A metal gasket comprising an elastic metal plate including beads formed around cylinder bore holes of a multiple-cylinder engine, wherein each bead comprises an independent bead formed around each hole, a common bead between an adjacent pair of holes and junction beads connecting the independent bead and the common bead. The metal gasket controls a spring constant at the junction beads to a suitable value by specifying the shape of the junction beads, reduces a peak value of a face-to-face pressure at the junction beads, reduces also drop of the face-to-face pressure occurring in the junction beads and at their boundary, and makes uniform the face-to-face pressure in the vicinity of the junction beads.
