【考案の詳細な説明】
従来の金属積層形ガスケツトは燃焼室穴の燃焼
室穴被覆材内にワイヤーリングを装置してシール
性能を高めているものがあるが、この従来のもの

の亀裂、微量ガスの漏れ、エンジンライナーの変
形増大等を起こすことがある。[Detailed explanation of the invention] Some conventional metal laminated gaskets have a wire ring installed in the combustion chamber hole covering material to improve sealing performance. may concentrate in a narrow area, causing cracks in the combustion chamber hole covering material, leakage of trace gases, increased deformation of the engine liner, etc.
本考案は斯様な従来の欠点を回避し、ガスのシ
ール性能を尚一層高めたこの種のガスケツトを提
供することを目的として案出したのである。 The present invention has been devised for the purpose of avoiding such conventional drawbacks and providing a gasket of this type that has further improved gas sealing performance.

る。 The drawing shows an embodiment of a metal laminated gasket for a cylinder head according to the present invention, in which a first intermediate plate 3 and a second intermediate plate are provided between an upper plate 1 and a lower plate 2, which serve as relief plates for adjusting the surface pressure of the bead. Intermediate plate 4 and third intermediate plate 5
A bead 7 is provided on the edge 4a side of the second intermediate plate 4 around the combustion chamber hole 6, and the edge 3a of the first intermediate plate 3 on the combustion chamber hole 6 side is connected to the other intermediate plates 4, 6. edge 4
a, 5a so that the bead 7 is in contact with the upper plate 1 at a distance outward, and the tip of the lower plate 2 is folded back at the combustion chamber hole 6 portion and placed closer to the combustion chamber hole 6 than the bead 7, The wire ring 8 surrounding the combustion chamber hole 6 and the bead 7 are wrapped to form a combustion chamber hole covering material 9, and the tip 10a of the folded piece 10 of the combustion chamber hole covering material 9 is connected to the tip 10a. When the gasket A is tightened between the gasket A and the tip 3a of the intermediate plate 3, a gap b sufficient for bending the upper plate 1 is formed.
なお、図面で示すｖはワイヤーリング８部の面
圧量を、また、v′はビード７部の面圧量をそれぞ
れ示す。 Note that v shown in the drawings represents the amount of surface pressure on the wire ring 8 portion, and v' represents the amount of surface pressure on the bead 7 portion.
本考案は前記の通りの構成であるから、機関作
動時に何等かの原因でワイヤーリング部の面圧が
下ると、ビード部側がこれを補填してガスシール
に必要な面圧を確保し、次段階としてビード部の
面圧が低下すると今度はワイヤーリング部が該面
圧の低下を補填し、総体的にはガスシールに必要
な面圧を確実に保持し、品質の良いこの種のガス
ケツトを提供できるのである。 Since the present invention has the above-mentioned configuration, if the surface pressure of the wire ring part decreases for some reason during engine operation, the bead part compensates for this and secures the surface pressure necessary for gas sealing, and then As a step, when the surface pressure of the bead part decreases, the wire ring part compensates for the drop in surface pressure, and as a whole, it reliably maintains the surface pressure necessary for gas sealing, making this type of gasket of good quality. We can provide it.
