ABSTRACT:
A steel laminate gasket of the invention is installed in an internal combustion engine having at least one hole to be sealed. The gasket comprises first and second plates, at least one middle plate situated between the first and second plates, and a cover member situated outside the hole of the engine to surround the same. A ring member is situated adjacent to the cover member. At least one protecting plate is placed over the ring member and at least a part of the middle plate. The protecting plate is made of a material harder than the ring member. Therefore, when the gasket is tightened, the gasket and the engine blocks do not deform, and wide and strong sealing pressure is obtained.
