Abstract
This metal gasket is formed by interposing a shim member between a pair of elastic metal plates, and fixing the shim member and one of the elastic metal plate to each other at the portions thereof which are opposed to a water jacket, whereby the function of the shim member is secured with the fixed portions and opposed surfaces not interfering with each other. The shim member comprises a shim member body corresponding to an end surface of a cylinder body of a cylinder block, and projecting portions integral with said shim member body and extending therefrom to a position opposed to the water jacket. The fixing portions at which the shim member and one elastic metal plate are fixed to each other by crimping are positioned on the projecting portions extending to positions opposed to the water jacket. Therefore, when the metal gasket is tightened between the cylinder block and a cylinder head, the fixed portions do not interfere with the opposed surfaces thereof including end surfaces, and the sealing function of the metal gasket is not spoiled.
