Metal laminate gasket with bore ring and engaging members thereof

摘要

A metal laminate gasket for an internal combustion engine is formed by a first metal plate having a first hole corresponding to a hole of the engine, and a bore ring and a second metal plate both being disposed under the first metal plate. The bore ring has a second hole corresponding to the first hole, and at least two first engaging members formed around an outer periphery thereof with a predetermined distance away from each other. The second metal plate includes a third hole having a size for receiving the outer periphery of the bore ring, and at least two second engaging members formed around an inner periphery thereof to engage the at least two first engaging member. The first and second engaging members are arranged such that the bore ring can be positioned and retained in the second metal plate in only one position even if the bore ring is positioned upside down.
