Abstract
A metal gasket for sealing multiple cylinder bores includes one or more metal substrates, main sealing beads around each of the cylinder bores, and one or more sub-beads. The main sealing beads include meandering portions located in a sealing portion between the cylinder bores, and the sub-bead is provided between the meandering portions. By placing the sub-bead between the main bead meandering portions, the base portion of the meandering portion and the base portion of the sub-bead squeeze each other. As a result, the lower portion of the meandering portion can be prevented from slipping, and the surface pressure can be partially reinforced. The metal gasket provides an excellent seal in a location where surface pressure is often partially reduced.
