ABSTRACT:
The gasket of the invention is used for an internal combustion engine, and is basically formed of first, second and third plates for sealing around a hole of the engine. The first plate includes a curved portion to define the hole of the engine, and a flange extending from the curved portion. The second plate is located under a base portion of the first plate, and includes a hole larger than the flange. The third plate includes an inner portion, an outer portion and a bead situated between the inner and outer portions. The inner portion is located between the flange and the base portion, and the outer portion is located under the second plate. The bead extends through a space between the flange and the second plate, so that pressure applied to the bead is entirely directly supported by the plates under the inner portion and the outer portion. No distortion is formed on the plates by compression of the bead.
