ABSTRACT:
This metal gasket for chain case-carrying engines is capable of reliably preventing the entry of an oil into height different parts, which occur on abutting surfaces of a cylinder block and a chain case, even when the oil deposited on the chain case scatters during a movement of a chain, and improving the reliability thereof owing to its durability. This metal gasket has first and second elastic metal plates provided with beads extending along an opening, in which the chain moves, and an intermediate plate provided with bores packed with seal members for sealing the height different parts occurring at the abutting surfaces of the chain case and cylinder block. The second elastic metal plate is provided with recesses formed by cutting out the portions thereof in which the seal members are positioned.
