【考案の詳細な説明】
本考案は部材接合面の気密性を損うことなく接合部材の
分解時の剥離性向上を図ったガスケット体に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gasket body that improves the releasability of joined members during disassembly without impairing the airtightness of the joining surfaces of the members.
内燃機関のクランクケースの台面などに使用さｎる従来

部材を分解するに際しては密着性の高いシール剤のため
に接合された両部材の分解作業を困難ならしめていた。Conventional gasket bodies for room temperature and low pressure applications, such as those used on the base of the crankcase of an internal combustion engine, are coated with a highly adhesive sealant on both the front and back surfaces to airtightly bond the joint surfaces of both parts. Although high airtightness is ensured, the highly adhesive sealant makes it difficult to disassemble the two joined members.

容易に行えるようにしたものである。In view of the above circumstances, the present invention has a three-layer structure in which a soft adhesive layer such as silicone with good releasability is formed on the surface of the gasket serving as the core material, and this surface is covered with an adhesive layer of a sealant with high adhesiveness. By using a gasket body, the airtightness of the joint surfaces of the parts is ensured by a highly adhesive sealant, and when the parts are disassembled, the joint surfaces of both parts can be easily peeled off by the soft adhesive layer with good releasability. This is what I did.
次に本考案ガスケット体を図面に示す実施例で説明する
。Next, the gasket body of the present invention will be explained with reference to embodiments shown in the drawings.
第１図において、Ｇは本考案の常温低圧用のガスケット

、麻、クリンゲット等の非金属性の素材を薄板に圧搾加
工したものである。In FIG. 1, G is a gasket body for normal temperature and low pressure according to the present invention, and the gasket material 10 serving as the core material is paper, phi:/<
It is made by pressing non-metallic materials such as , hemp, and kringet into thin sheets.
２０は比較的に剥離性の良い例えばシリコン系のシール
剤をガスケット材１０の表裏全面に薄く塗布して形成し
た軟着層である。Reference numeral 20 denotes a soft adhesive layer formed by thinly applying a relatively releasable sealant, such as a silicone-based sealant, to the entire front and back surfaces of the gasket material 10.
３０は上記軟着層２０を被うようにこの表面に塗布され
た密着性の高いシール材（シール層）で、例えばニトリ
ル系ゴム等の適宜のシール剤が使用される。30 is a highly adhesive sealing material (sealing layer) applied to the surface of the soft adhesive layer 20 so as to cover it, and an appropriate sealing material such as nitrile rubber is used, for example.
上述のようにしてガスケット体Ｇは該ガスケット材１０
とシール層３０の間に剥離性の良い軟着層２０を介在さ
せた三層構造となっている。As described above, the gasket body G has the gasket material 10
It has a three-layer structure in which a soft adhesive layer 20 with good releasability is interposed between a sealing layer 30 and a sealing layer 30.
本考案のガスケット体Ｇは前述のように三層構造を呈し
ているので、両部材（図示なし）の接合に際してはシー
ル層３０が両部材の接合面に強力に接合して高い気密性
を発揮する。As described above, the gasket body G of the present invention has a three-layer structure, so when the two members (not shown) are joined, the sealing layer 30 is strongly joined to the joint surfaces of the two members and exhibits high airtightness. do.
そして当該ガスケット体Ｇで接合された両部材の分解（

される。Then, disassembly of both members joined by the gasket body G (
During separation), either position a or a' of the flexible layer 20, which has good releasability, i.e., weak bonding strength against tensile force, is peeled off by a relatively small external force F, and both members are easily separated. .
かくして、当該ガスケット体Ｇによるときは部材接合面
の気密性を損うことなく部材分解時の剥離性の向上を図
る効果がある。Thus, the use of the gasket body G has the effect of improving releasability during disassembly of the members without impairing the airtightness of the joining surfaces of the members.

層２０が剥れることとなる。As shown in FIG. 2, the gasket body of the present invention has a soft adhesive layer 20 with good releasability interposed only on at least one side, for example, the bottom surface, of the gasket material 10 covered with a highly adhesive sealing layer 30. A three-layer structure may also be used, in which case the soft layer 20 at position a' will peel off due to external force F when the joining member is disassembled.
