ABSTRACT:
The gasket of the invention is installed in an internal combustion engine having a hole to be sealed. The gasket is formed of first and second outer plates, and a middle member situated between the outer plates. A main sealing member formed of a wire ring is situated between a base portion of the first outer plate and the second outer plate around a curved portion of the first outer plate to define the hole of the engine. An auxiliary sealing member having a thickness less than that of the main sealing member is situated between the curved portion and the main sealing member. When the gasket is tightened, the main sealing member is compressed up to the thickness of the auxiliary sealing member to provide moderate surface pressure by the auxiliary sealing member near the hole and high surface pressure by the main sealing member away from the hole to be sealed. The surface pressure of sealing portions can be easily controlled.
