Although the seal tends to be insufficient, one method of effectively covering the seal that extends around the periphery of the six holes is to attach a glue to the periphery of the six holes.

Since the contact between ~, cylinder head J3, and cylinder block was metal-to-metal contact, there was a drawback that leakage would occur unless the tightening force of the gasket was increased.1=.

を提供づることを目的とする。The present invention has been made in order to solve the above-mentioned drawbacks of the conventional technology. The purpose of the present invention is to provide a grommet that does not cause cross flow (flow >7), has a high heat-resistant temperature limit, and can be used even in high-temperature environments.

以下、本発明を図面に示す実施例に基づいてさらに詳細
に説明する。Hereinafter, the present invention will be explained in more detail based on embodiments shown in the drawings.
第１図および第２図は本発明の一実施例を示づ。1 and 2 show one embodiment of the invention.

グ［１メツ１〜６が装着されている。1 is the gasket body of the cylinder head gasket, and this gasket body 1 includes a steel plate 3 with claws 2 punched out on both sides, and a rubber plate 7 crimped on both sides of the steel plate 3.
It is composed of a smooth material 1 and a sheet-like material 4 made of a non-metallic material 1'l such as a compound. At the periphery of the water hole J or oil hole 5 provided in the gasket body 1,
[1 Metz 1 to 6 are installed.

止材層９とからなる。The grommet 6 includes a base body 7 made of metal such as steel, and a layer 8 (hereinafter referred to as a rubber/compressible fiber layer) of a mixture of rubber and compressible fibers such as asbestos coated on the surface of the base body 7. and an anti-adhesion material layer 9 coated on the surface of the rubber/compressible material 8 in order to prevent the adhesion of the cassette to the cylinder heads iI3, J: and the cylinder block.
ここで、前記圧縮性繊維としては、石綿の他に、レルロ

、同様の圧縮性を右づる繊維を使用づることがてきる。Here, as the compressible fiber, in addition to asbestos, fibers having similar compressibility such as lerulose fiber, cork, carbon fiber, etc. can be used.

ましい。In addition, the mixing ratio of rubber and compressible fibers in the rubber/compressible layer 8 is, for example, in the case of a combination of rubber and asbestos, 3 to 3 asbestos to 1 part by weight of rubber. It is preferable that the amount is about 7 parts by weight. Further, the thickness of the rubber/compressible fiber layer 8 is preferably about 50 to 100 microns.

、小さな締付力でも、漏れを生じることがない。In this Chromet 6, the rubber/compressible fiber layer 8 with appropriate softness is brought into contact with the cylinder head and cylinder block via the anti-adhesive material layer 9, so even a small tightening force will prevent leakage. It never occurs.
また、仮に、ゴム・圧縮性繊維層８がゴム単体であると

、漏れを起こす虞がある。Furthermore, if the rubber/compressible fiber layer 8 is made of rubber alone, due to reasons such as low rigidity of the cylinder head and cylinder block, the surrounding areas of the gasket holes (not shown), etc. When a large stress is applied to the layer 8, the compressive elastic limit is exceeded, causing a lateral flow,
1- Luktown will increase. Further, accompanying this, thermal deformation or structural deformation (deformation not based on thermal load) of the cylinder head and cylinder block increases, which may cause leakage.

、十分なトルク保持力が得られる。However, since the rubber/compressible fiber layer 8 is made of a mixture of rubber and compressible fibers rather than a single rubber element, a large stress is applied to the rubber/compressible fiber layer 8. Moreover, since the thickness of the layer 8 is thin, sufficient torque holding power can be obtained.
また、上述のように、ゴム・圧縮性繊維層８は、ゴム単

言うまでもない。a3, the above embodiments describe the present invention in cylinders and spatulas 1 to 1.
Although examples have been shown in which the present invention is applied to grommets 1 to 1 to which are inserted into the water holes and oil holes of the cassette, it goes without saying that the present invention can also be applied to grommets installed in various holes of the cassette.

It is something that can be admired.
