【発明が解決しようとする課題】しかし、上記従来の接
着方法においては、接着剤の塗布量を適量に調節するこ
とが極めて困難であると云った問題点があった。However, in the above-mentioned conventional bonding method, there is a problem that it is extremely difficult to adjust the coating amount of the adhesive to an appropriate amount.
【０００４】すなわち、接着剤の塗布量が少ないと、接
着面積が減少するので、当然のこととして接着力が不足
すると云った問題を生じ、全体として適量に近い塗布が
行われていても、図４右側に示したような接着剤３の縁
部３１の変動は避け難い。That is, when the amount of adhesive applied is small, the adhesive area is reduced, which naturally causes a problem that the adhesive strength is insufficient. 4 It is difficult to avoid the fluctuation of the edge portion 31 of the adhesive 3 as shown on the right side.
【０００５】縁部３１が上記のように変動していると、

ことを特徴とする接着方法を提供するものである。In order to solve the above-mentioned problems, the present invention forms a concave portion which is close to or continuous with the outer peripheral edge portion of the adhesive surface of at least one of the members, and is surrounded by the concave portion. The adhesive is applied to the adhesive surface of at least one of the members to spread the adhesive by applying pressure between the members arranged with the adhesive surfaces facing each other.
The bonding method is characterized in that the members are bonded to each other via the spread adhesive.

圧する。A liquid resin curable adhesive (hereinafter simply referred to as "adhesive") 3 such as an epoxy resin adhesive is applied to a portion of the adhesive surface 11 of the member 1 surrounded by the concave portion 13. Then, the member 1 is pressed to a predetermined position of the member 2 with the adhesive surfaces facing each other while the adhesive 3 can still flow.

がある。Therefore, the edge portion 31 of the adhesive 3 does not fluctuate as in the conventional bonding method, so that stress concentration is not received and the breaking strength is remarkably improved. Further, even if the adhesive 3 is applied slightly larger to prevent the adhesive strength from becoming insufficient due to the insufficient adhesive area, the adhesive 3 that is spread and excessive during the work of closely adhering the adhesive surfaces is Since it does not enter the concave portion 13 and protrudes to the outer peripheral edge portion 12, there is an advantage that the allowable range of the adhesive application amount is widened.

なくなるため、前記した実施例１と同様の作用効果が得
られる。Also in the bonding method of the second embodiment,
When the adhesive 3 is applied to the adhesive surface 11 of the member 1 and the member 1 is pressed against a predetermined portion of the member 2 while the adhesive 3 is still flowable, the adhesive surfaces are pressed against each other. It is sandwiched between the adhesive surface 11 of No. 1 and the adhesive surface 21 of the member 2 and thinly extended, and the edge portion 31 expands toward the outer peripheral edge portion 12, but the recessed portion 13 continuous to the outer peripheral edge portion 12 is formed. Since the adhesive 3 that has spread up to this point is
Since there is no adhesive 3 that enters and further protrudes from here, the same operational effect as that of the above-described first embodiment can be obtained.
【００１８】なお、本発明は上記実施例に限定されるも
のではないので、特許請求の範囲に記載の趣旨に沿って
各種の変形実施が可能である。Since the present invention is not limited to the above-mentioned embodiments, various modifications can be made within the scope of the claims.
【００１９】例えば、接着剤３は凹陥部１３が形成され

まの状態、すなわち不均一な厚さに付着させたものであ
っても構わない。Arrangement of the adhesive 3 on the adhesive surface is generally referred to as "application". Therefore, the term "application" is used in the present invention, but a brush or the like is used on the adhesive surface with a relatively uniform thickness. In addition to the application by coating, it may be in a state of being extruded from a tube or the like, that is, applied in a non-uniform thickness.
