本考案は、金属板を素材とするガスケツトの開
口周縁部にビードを設けたメタルガスケツトに関
するものである。[Detailed Description of the Invention] The present invention relates to a metal gasket in which a bead is provided on the periphery of the opening of the gasket made of a metal plate.
第４図および第５図において、１，２はメタル
ガスケツトを構成する金属板（通常鋼板を使用す

ていた。 However, the conventional metal gasket of this type has 2
In order to join the two overlapping metal plates 1 and 2, for example, a plurality of (six in the drawings) tongue pieces 6 are provided protruding from the outer edge of the metal plate 2, and these are connected as shown in FIG. The overlapped metal plates 1 and 2 were joined together by folding the other metal plate 1 between them.

め、矢印Ｐの水平分力ｐによつて金属板１が若干
摺動する結果、ビード４と接合面との接触圧力が
それだけ減少して封塞性能が低下するという問題
点があつた。 However, when the metal gasket constructed in this way is inserted between the cylinder block and the cylinder head and tightened with bolts, a force shown by the arrow P in FIG.
is relatively easy to slide against the overlapping metal plate 2, so the metal plate 1 slides slightly due to the horizontal component p of the arrow P, and the contact pressure between the bead 4 and the joint surface is reduced accordingly. There was a problem that the sealing performance deteriorated.
本考案は上述の問題点を解決するために考案し

性能を向上させることを目的とするものである。 The present invention was devised in order to solve the above-mentioned problems.A ring-shaped recess is formed at a position slightly outside the opening periphery of the metal plate forming the gasket, and a bead ring is formed in the ring-shaped recess. The purpose of this is to increase the contact pressure between the bead and the joint surface and improve the sealing performance of the gasket by fitting the hem of the bead and restraining the hem of the bead.
以下、第１図〜第３図により本考案の実施例を
説明する。図中前記した符号と同一の符号は同等
のものを示す。 Embodiments of the present invention will be described below with reference to FIGS. 1 to 3. In the drawings, the same reference numerals as those described above indicate equivalent parts.
第１図および第２図の実施例においては、ガス

縁よりやゝ外側位置に環状の凹陥部８を形成し、
この凹陥部８に、他の素材により環状に形成した
ビードリング９を嵌着してメタルガスケツトを構
成する。 In the embodiment shown in FIGS. 1 and 2, an annular recess 8 is formed at a position slightly outside the periphery of the cylinder opening 3 in the metal plate 7 forming the gasket.
A bead ring 9 formed into an annular shape made of another material is fitted into this concave portion 8 to form a metal gasket.
なおこの場合、凹陥部８はフライス盤等の機械
加工により形成すればよく、またビードリング９
を凹陥部８に嵌着するには、溶接または接着剤を
使用するか、あるいは凹陥部８にビードリング９

９を嵌入後かしめてもよい。 In this case, the concave portion 8 may be formed by machining using a milling machine or the like, and the bead ring 9
to fit into the recess 8 by welding or using adhesive, or by inserting a bead ring 9 into the recess 8.
The bead ring 9 may be press-fitted and fixed, or the bead ring 9 may be crimped after being fitted.
また第３図の実施例は、凹陥部８を形成するた
めに、所定の形状に打ち抜いた３枚の金属板１
０，１１，１２を一体に接合して凹陥部８を形成

９を嵌着したものである。 Further, in the embodiment shown in FIG. 3, three metal plates 1 are punched out in a predetermined shape to form the concave portion 8.
0, 11, and 12 are integrally joined to form a concave portion 8, and a bead ring 9 formed in an annular shape is fitted into this concave portion 8.
この場合３枚の金属板１０，１１，１２を接合
する方法は、どのような方法でもよいが、抵抗溶
接が好適である。 In this case, any method may be used to join the three metal plates 10, 11, 12, but resistance welding is preferred.
本考案のメタルガスケツトは上述のように構成

より高くして封塞性能を向上させることができる
という効果が得られる。 Since the metal gasket of the present invention is configured as described above, when this metal gasket is inserted between the joint surfaces and tightened, the hem of the bead ring 9 will touch the other metal plates 7, 10, 11, 12. Since it fits into the recessed part 8 formed by, it will not escape. Therefore, unlike conventional metal gaskets, the hem of the bead 4 does not easily slide and the contact pressure between the bead 4 and the joint surface does not decrease, and in the metal gasket of the present invention, the bead ring 9 The effect is that the contact pressure between the bead and the joint surface can be made higher than that of the conventional method, and the sealing performance can be improved.
