ABSTRACT:
The exhaust manifold gasket according to present invention consists of a pair of beaded plates provided with beads extending along the circumferences of exhaust holes therein, and a piled plate assembly inserted between these beaded plates. The piled plate assembly consists of a pair of flat plates, and a refractory sheet member disposed between these flat plates and containing a core plate therein. The refractory sheet member is formed out of a material having a high thermal resistance, excellent heat insulating characteristics and a high compression resiliency at a high temperature, such as a mica material. Accordingly, this exhaust manifold gasket has an improved compression resiliency at a high temperature and an improved sealability at a high temperature, and is capable of properly cutting off the transfer of heat.
