2. Description of the Related Art In an internal combustion engine, a sealing function is provided by fastening a joint surface between a cylinder block and a cylinder head with a gasket interposed therebetween. In particular, the seal around the combustion chamber is important, and if the seal in this part is insufficient, the utilization of the combustion gas inside the combustion chamber becomes incomplete, and this appears as a pressure drop. Therefore, a bead is provided concentrically with the combustion chamber hole provided in the elastic substrate of the metal gasket, and a sealing function is provided to the periphery of the combustion chamber by utilizing the repulsive force of the bead generated when the metal gasket is tightened by the bolt. It has a configuration.

At this time, in order to prevent fatigue damage of the bead, for example, a stopper is provided in a flat portion between the combustion chamber hole of the metal gasket and the bead to limit the magnitude of the bead amplitude. Various proposals have been made for the installation position and shape of the stopper.
In this technique, as shown in FIG. 5, a full bead 2 is formed on one substrate 1 and a shim plate 3 is fixed to a flat portion near the bore from the bead, and the bead is fully bent and operated. This is a method used as a stopper to prevent the vibration amplitude of the vibration.

Recently, due to rapid technological innovation of the internal combustion engine, miniaturization, weight reduction, high output, and fuel saving have been promoted. As a result, the fuel has become lean, and auxiliary devices such as a supercharger have been installed. As the combustion temperature increases, the vibration amplitude of the cylinder head tends to be further increased by the weight of the replenisher. In accordance with the above-mentioned conventional technology, a stopper is formed by welding and fixing a shim plate serving as a sub-plate to a flat portion of a metal gasket between a bore bead provided at a peripheral edge of a bore and a cylinder bore.

[0005] However, as the size of the engine is reduced, the width between the cylinder bores is reduced, and as a result, the width of the stopper between the cylinder bores is necessarily reduced. Therefore, the surface pressure on the sub-plate becomes locally high. In addition, the weight of the cylinder head with accessories and the vibration amplitude generated during engine operation are applied in a wave-like manner, and furthermore, the body expands and the engine surface gradually sinks, resulting in the effect of the stopper being less effective. Get up.

In addition, when a shim plate as a sub-plate is welded to a substrate by continuous spot welding over the entire circumference of the cylinder bore at the time of manufacturing, when a gasket has a narrow portion, a gap between adjacent cylinder bores or a long water hole, etc. Thermal distortion occurs due to a difference in conduction of heat generated during welding in a narrow portion of the flat portion outside the bead. As a result, the product is curved, and various problems occur in the post-process. Further, when assembled into the engine as a finished product, the knocking hole guide to be positioned may be bent and deformed and come off, damaging the gasket, impeding automatic assembly, and deteriorating the work efficiency.

In order to achieve the above object, in a metal gasket in which two thin elastic metal substrates are laminated, a combustion chamber hole, a water hole, a bolt hole, and an oil hole are provided in the two substrates. The combustion chamber hole is provided with a full bead along the peripheral edge thereof, the sub-plate is sandwiched between the two substrates with the combustion chamber side ends aligned, and the other end of the sub-plate is burned. Extending to a range over a full bead provided along the periphery of the chamber hole, the substrate and the sub-plate are fixed to only one of the two substrates, and the fixing portion is between adjacent bores and It was a portion excluding the portion between the bore hole and the water hole.

First, when the metal gasket is mounted on the engine and tightened, the bead of the sub-plate and the substrate is deformed from the one with the lower spring constant, and deformed with a delay of the difference between the spring constant of the substrate and the sub-plate bead. Basically, the bead is designed to bend all the way when the gasket is completely tightened.However, the auxiliary plate exists only on the periphery of the cylinder bore, and the tightening bolt is only the substrate. Then, in the cylinder bore, an inclination corresponding to the thickness of the sub-plate occurs.

That is, the spring of the engine is used by bending the engine, and the local deformation is followed by the two beads of the substrate and the sub-plate, and the vibration generated at the time of the explosion by the spring of the cylinder head. The amplitude is suppressed to prevent bead fatigue destruction, and by increasing the width of the sub-plate, the surface pressure does not locally become excessive, and there is no fear that the engine will be dented. Further, two beads equivalent to two substrates are formed in the gasket that can guarantee high performance for a long time with a sufficient deformation follow-up amount.

The flat portion closer to the bore hole than the bead (a portion having a plane extending from the end of the bore hole to the rising portion of the bead provided at the periphery of the bore hole at the periphery of the bore hole) is formed on the fixing portion 8. Fixed. 1A, there is no difference in the bead width (the length from the start point to the end point of the bead) between the substrate beads 9-1 and 9-2 and the sub-plate bead 11, but the thickness of the sub-plate 6 is not changed. Is smaller than or equal to the plate thickness of the substrate 1-1, and when they are equal to each other, the bead width is narrowed to make the spring constant different. In addition, since the rigidity of the engine is becoming weaker, the tightening surface pressures between bolts and near bolts are usually different. Therefore, in order to average the bead upper surface pressure, the bead width is changed near the bolts and narrowly between the bolts.

FIG. 1B is a sectional view taken along the line AA ', so that the width of the gasket is narrow between the two bores. Therefore, when the sub-plate 6 is fixed to the substrate 1-1 by spot welding in a continuous manner, thermal distortion is generated in the narrow portion, which causes the portion to bend. Therefore, the portion other than the portion where heat distortion is likely to occur is fixed, so that there is a portion without fixing. There is another portion where there is no fixation in this way, and the water hole 5 is this. That is, since the water hole 5 is located near the bore hole and becomes a portion that causes a long thermal strain deformation, the vicinity of the water hole is also excluded. Therefore, there may be a case where the fixing line is broken at several places around one bore hole.

Next, the operation will be described. First, when the metal gasket is mounted on the engine and tightened, if the sub-plate and the substrate have the same plate thickness, the bead width of the substrate is large and the spring constant is small, so it changes rapidly and quickly, but the sub-plate changes with a delay, The basic rule is that when both beads are fully tightened, they bend over. However, since the sub-plate exists only at the peripheral edge of the bore, and other than the tightening bolt portion is only the substrate, an inclination corresponding to the thickness of the sub-plate occurs between the bolt portion and the bore portion at the time of tightening. That is,
The engine is flexed and the engine spring is used.

This phenomenon is the same as that of the prior art, but the present invention is characterized in that the auxiliary plate has both the stopper function and the bead function. Also, in order to widen the application range, the thickness of the sub-plate, the hardness, the shape of the bead, the width of the bead, the combination of the direction of the bead, etc. are supported. Since the bolts are narrow and the engine stiffness is weak, some gaps occur.

It is necessary to suppress deformation due to so-called thermal strain, which occurs when the substrate and the sub-plate are fixed by continuous spot welding. Therefore, it is necessary to suppress the deformation between adjacent bores having a narrow gasket width and between the bore hole and the water hole. Except for a portion having a condition for deformation, the portion is fixed. That is, the gasket has a range that does not adhere to the narrow portion.
