<p>A cylinder head gasket includes two main members 1 and 4 on two sides, and middle members sandwiched therebetween. The middle members are composed of a first middle member 2 and a second middle member 3 that is separated and distinct therefrom. The first middle member 2 is a metal plate that has cylinder hole rim portions 21 encircling cylinder holes 12 to a particular width, with beads surrounding the cylinder holes 12 being formed in the cylinder hole rim portions 21. The metal plate either forms separated items, one at each cylinder hole, or else forms an integrated item connected between the cylinder holes 12. The second middle member 3 is a metal plate that is disposed on the outside of the first middle member 2 and has oil holes 16 and bolt holes 15. The thickness of the first middle member 2 is greater than that of the second middle member 3. Such structure can provide superior following ability with regard to the cylinder head lift, retain the cylinder head lift via the gasket, and reduce the amount of material.</p> |
