ABSTRACT:
A metal gasket of the invention is designed to reduce heat transfer between two engine parts. The gasket is formed of at least two plates having holes to be sealed and bolt holes, a sealing device formed around the hole to be sealed, and a space forming device formed on at least one of the plates to separate the plates apart. Spacers are formed around the bolt holes so that bolts can be tightened up to a predetermined thickness. When the gasket is tightened, the sealing device is compressed to seal around the hole, but the two meal plates do not closely abut against each other by means of the space forming device. Accordingly, heat is partly radiated through the gasket, and heat transmission between the engine parts is reduced.
