Abstract
A cylinder head gasket 1 has gasket base plates 4 and 5 including: combustion chamber holes 7; a water hole 9 formed in a manner adjusted to the position of a cooling liquid path 3b formed in a cylinder block; and full beads 4a and 5a surrounding the combustion chamber holes.Neighboring full beads are formed at locations distant from each other. Furthermore, two coupling beads 4b and 5b are provided at locations having disposed therebetween a centerline connecting the centers of the neighboring combustion chamber holes, and the two coupling beads 4b and 5b branch out from one full bead and join the other full bead and protrude in the same direction as the full beads.The water hole is disposed outside an area surrounded by the full beads and the coupling beads.
