Abstract
A metal gasket is disclosed which is used arranged between a cylinder block and a cylinder head. The metal gasket comprises carrier plates having thereon beads, and a stopper plate overlaid on the carrier plates and provided with folded constructions, which are each composed of a folded flange area and its counterpart area confronting each other so as to provide a gap of a preselected interval between them. The gaps exert elasticity on the folded flange areas continuously whenever the gasket is squeezed and loaded due to engine operation whereby the folded constructions may compensate for intolerable clearance that might occur owing to the distortion in fatigue of the cylinder block with respect to the gasket, with resulting in improving sealing performance of the gasket.
