Abstract
A cylinder head gasket is provided for dealing with gas leak between cylinder bores of an engine with a reduced size and rigidity. A cylinder head gasket is formed of one or more metal plates. One metal plate is provided with a first bead, a second bead, and a third bead arranged from inside in this order around a cylinder bore. The first bead is formed around each of the cylinder bores. The second beads are combined into a single bead having a width greater than a width of other section of the second beads in an area between adjacent cylinder bores. The third bead does not pass through the area between the adjacent cylinder bores and surrounds all of the cylinder bores.
