摘要： 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.

摘要： A metal gasket used in an engine with a chain case, using a foam-rubber seal member shaped to withstand in practical use and having excellent long-lasting reliability and excellent durability. A total constitutive plate of the metal gasket is extended along the chain case to form an extended part. This extended part has a chain case hole. The foam-rubber seal member seals a chain case opening and a three-surface joining portion defined by the chain case, a cylinder block and a cylinder head. The foam-rubber seal member is a separate and distinct member and is a sheet-like and loop-like combination of layers of foam rubber and a metal core plate interposed between these foam rubber layers.

摘要： An engine gasket flattens the surface pressure occurring around holes, prevents the occurrence of impressions in and damage to a cylinder block and a cylinder head, and secures a stable sealing performance. This metal gasket has elastic metal plates and an intermediate metal plate interposed between these elastic metal plates. The elastic metal plates are provided with full beads along the circumferences of the holes so that the ridge portions of the full beads contact the intermediate metal plate. The intermediate plate has, on regions which are between the holes and full beads of the elastic metal plates, half beads extending toward the elastic metal plates. The elastic metal plates are folded back along the circumferences of the holes.
