本発明は、ガラス複合体と、ガラス複合体を用いた入力装置、及び電子機器に関し、特にガラス部材と枠体の接合部に作用する剥離応力（内部残留応力）を低減できるガラス複合体の構造に関する。   The present invention relates to a glass composite, an input device using the glass composite, and an electronic device, and in particular, a structure of a glass composite that can reduce peeling stress (internal residual stress) acting on a joint between a glass member and a frame. About.

各特許文献には、本体部と、その周囲に位置する枠体との間を接着部材により接合してなる複合体の構成が開示されている。特許文献１等には本体部がガラスであるとの記載がある。   Each patent document discloses a configuration of a composite body in which a main body portion and a frame body positioned around the main body portion are joined by an adhesive member. Patent Document 1 and the like describe that the main body is glass.

各特許文献では、本体部の側面と前記側面と対向する枠体の側壁部とは平面に対して直交する垂直面で形成され、側面と側壁部との間に形成された隙間内に接着剤が介在する構成となっている。   In each patent document, the side surface of the main body portion and the side wall portion of the frame opposite to the side surface are formed by a vertical surface orthogonal to the plane, and the adhesive is formed in a gap formed between the side surface and the side wall portion.

しかしながら、熱が加わった際、枠体とガラス部材との線膨張係数の違いから、従来の構成では、ガラス部材と枠体との間の接合部分に大きな剥離応力（内部残留応力）が作用し、特に垂直面とされた側面及び側壁部のコーナー部分で強い剥離応力が作用することがわかった。   However, when heat is applied, due to the difference in coefficient of linear expansion between the frame body and the glass member, in the conventional configuration, a large peeling stress (internal residual stress) acts on the joint between the glass member and the frame body. In particular, it has been found that strong peeling stress acts on the side surface and the corner portion of the side wall portion, which are particularly vertical surfaces.

そこで本発明は上記従来の課題を解決するものであり、特に従来に比べて剥離応力（内部残留応力）を低減できるガラス複合体、ガラス複合体を用いた入力装置及び電子機器を提供することを目的としている。   Accordingly, the present invention solves the above-described conventional problems, and in particular, provides a glass composite that can reduce peeling stress (internal residual stress) compared to the conventional technique, an input device using the glass composite, and an electronic apparatus. It is aimed.

本発明は、 ガラス部材と、前記ガラス部材の側方を支持する枠体と、前記ガラス部材と前記枠体とを接着する接着部材と、を有して、その表面に入力装置の入力操作面が形成されるガラス複合体であって、
前記ガラス複合体は、表面と裏面とを有し、前記ガラス部材の表面が、前記入力操作面となっており、
前記ガラス部材を構成する複数の側面および前記複数の側面と対向する枠体の複数の側壁部が傾斜面を有し、前記側面と前記側壁部との間に、隙間が形成されて、前記接着部材が隙間内に充填されており、
前記隙間は、前記ガラス複合体の裏面側から表面側に向けて先細る形状で形成されるとともに、
隣り合う各側面間、及び隣り合う各側壁部間の夫々が、前記ガラス複合体の表面から裏面にわたって平面視で略円弧状となる円弧状コーナー部で構成されていることを特徴とするものである。 The present invention includes a glass member, and a frame for supporting the side of the glass member, and have a, a bonding member for bonding the said frame body and said glass member, the input operation surface of the input device on the surface A glass composite in which is formed ,
The glass composite has a front surface and a back surface, and the surface of the glass member is the input operation surface,
Said plurality of sidewalls of the plurality of sides and a plurality of side surfaces opposite to the frame body constituting the glass member has an inclined surface, between the side surface and the side wall portion, a gap is formed, the adhesive The member is filled in the gap,
The gap is formed by tapering shape toward the surface side from the back side of the glass composite Rutotomoni,
Between adjacent side surfaces, and each between the side walls adjacent, characterized in that it is constituted by an arcuate corner portion as a substantially arc shape in a plan view over the surface or found back surface of the glass composite Is.

本発明では、ガラス部材の側面と枠体の側壁部とを、その間の隙間が表面側に向けて先細る形状となる傾斜面で形成している。しかも本発明では、隣り合う各側面間、及び隣り合う各側壁部間の夫々が、表面から裏面にわたって平面視にて略円弧状の円弧状コーナー部で形成した。このように、側面及び側壁部を傾斜面としたことで、垂直面とした従来例に比べてガラス部材と枠体との接合部分に作用する剥離応力を低減でき、加えて、各側面間及び各側壁部間を円弧状コーナー部としたことで、コーナー部を円弧状とせず角張る形状とした比較例と比べて、剥離応力を低減でき、特に、接合部分の接着領域が狭まる表面付近での剥離応力を効果的に緩和することができる。   In this invention, the side surface of a glass member and the side wall part of a frame are formed in the inclined surface used as the shape where the clearance gap between them tapers toward the surface side. Moreover, in the present invention, each of the side surfaces adjacent to each other and between the side walls adjacent to each other is formed of a substantially arc-shaped corner portion in a plan view from the front surface to the back surface. Thus, by making the side surfaces and the side wall portions into inclined surfaces, it is possible to reduce the peeling stress acting on the joint portion between the glass member and the frame body as compared with the conventional example in which the vertical surfaces are used. By using arc-shaped corners between the side walls, the peeling stress can be reduced compared with the comparative example in which the corners are not arc-shaped but squared, especially near the surface where the bonding area of the joint is narrowed. The peeling stress can be effectively reduced.

本発明では、前記各側面間の円弧状コーナー部のほうが、前記各側壁部間の円弧状コーナー部よりも小さい円弧半径で形成されることが好ましい。これにより、各円弧状コーナー部間の間隔から各側面と各側壁部間の間隔にかけて略一定間隔に調整でき、剥離応力の低減を図るとともに接着部材をガラス部材と枠体との間の隙間に適切に充填でき、良好な接合状態を保つことができる。   In the present invention, it is preferable that the arc-shaped corner portion between the side surfaces is formed with a smaller arc radius than the arc-shaped corner portion between the side wall portions. Thereby, it can adjust to the substantially constant space | interval from the space | interval between each arc-shaped corner part to the space | interval between each side surface and each side wall part, and while aiming at reduction of peeling stress, an adhesive member is made into the clearance gap between a glass member and a frame. It can be filled properly and a good bonding state can be maintained.

At this time, the arcuate corner portions, respectively, preferably formed by an arc of a concentric circle whose center axis to a direction parallel to the thickness direction toward the surface or found back surface of the glass composite. Thereby, it is possible to reduce the peeling stress more effectively than when each arcuate corner portion is formed in a substantially arc shape with a constant radius from the front surface to the back surface.

また本発明では、前記ガラス複合体の表面における前記側面と前記側壁部との間にギャップが形成されていることが好ましい。これにより、効果的に剥離応力の低減を図ることができる。 Moreover, in this invention, it is preferable that the gap is formed between the said side surface and the said side wall part in the surface of the said glass composite . Thereby, reduction of peeling stress can be aimed at effectively.

本発明では、前記ガラス部材の表面と前記枠体の表面が、同一平面をなすことが好ましい。これにより剥離応力を効果的に低減できる。 In this invention, it is preferable that the surface of the said glass member and the surface of the said frame form the same plane . Thereby, peeling stress can be reduced effectively.

本発明では、前記枠体が樹脂で形成されることが好ましい。枠体を樹脂で形成することにより、ガラスよりも耐衝撃性に優れ、軽量且つ複雑な曲部や孔部を有する形状を容易に形成することができる。   In this invention, it is preferable that the said frame is formed with resin. By forming the frame body from resin, it is possible to easily form a shape that is superior in impact resistance to glass and that has a light and complicated curved portion or hole portion.

本発明における入力装置は、上記いずれかのガラス複合体と、前記ガラス複合体の裏面側に位置して、操作体で前記入力操作面上が操作されたことを検出可能なセンサ部材と、を有することを特徴とするものである。
An input device according to the present invention includes any one of the glass composites described above and a sensor member that is located on the back side of the glass composite and that can detect that the input operation surface has been operated with an operating body. It is characterized by having.

また本発明における電子機器は、上記入力装置の裏面側に、表示装置が配置されていることを特徴とするものである。   The electronic device according to the present invention is characterized in that a display device is arranged on the back side of the input device.

本発明によれば、ガラス部材と枠体との熱膨張係数の違いに基づく剥離が生じにくく、信頼性に優れた入力装置及び電子機器を提供できる。   ADVANTAGE OF THE INVENTION According to this invention, the peeling based on the difference in the thermal expansion coefficient of a glass member and a frame cannot produce easily, and the input device and electronic device excellent in reliability can be provided.

本発明では、ガラス部材の側面と枠体の側壁部とを、その間の隙間が表面側に向けて先細る形状となる傾斜面で形成している。しかも本発明では、各側面間、及び各側壁部間の夫々が表面から裏面にわたって平面視で略円弧状の円弧状コーナー部で形成した。このように、側面及び側壁部を傾斜面としたことで、垂直面とした従来例に比べてガラス部材と枠体との接合部分に作用する剥離応力を低減でき、加えて、各側面間及び各側壁部間を円弧状コーナー部としたことで、コーナー部を円弧状とせず角張る形状とした比較例と比べて、剥離応力を低減でき、特に、接合部分の接着領域が狭まる表面付近での剥離応力を効果的に緩和することができる。   In this invention, the side surface of a glass member and the side wall part of a frame are formed in the inclined surface used as the shape where the clearance gap between them tapers toward the surface side. Moreover, in the present invention, each side surface and each side wall portion are formed by arc-shaped corner portions that are substantially arc-shaped in plan view from the front surface to the back surface. Thus, by making the side surfaces and the side wall portions into inclined surfaces, it is possible to reduce the peeling stress acting on the joint portion between the glass member and the frame body as compared with the conventional example in which the vertical surfaces are used. By using arc-shaped corners between the side walls, the peeling stress can be reduced compared with the comparative example in which the corners are not arc-shaped but squared, especially near the surface where the bonding area of the joint is narrowed. The peeling stress can be effectively reduced.

本明細書での透光性とは、透明または半透明など光を透過可能な状態を意味しており、透過率が５０％以上で好ましくは８０％以上であることを意味している。ガラス部材１１は、通常ガラス、強化ガラス等、特に種類を限定するものではない。またガラス部材１１の線膨張係数は、８ｐｐｍ／Ｋ〜１０ｐｐｍ／Ｋ程度である。   The translucency in this specification means a state capable of transmitting light such as transparent or translucent, and means that the transmittance is 50% or more, preferably 80% or more. The glass member 11 is not particularly limited in kind, such as normal glass or tempered glass. The linear expansion coefficient of the glass member 11 is about 8 ppm / K to 10 ppm / K.

一方、枠体２０は透光性部材を用いており、例えば、その一部が着色されている。例えば、枠体２０は金型に熱可塑性樹脂を充填して成形したものである。例えば、枠体２０は、ポリカーボネート（ＰＣ）やポリメタクリル酸メチル（ＰＭＭＡ）で形成される。なお枠体２０には熱可塑性樹脂以外に、熱硬化性樹脂や光硬化性樹脂を用いることが可能である。枠体２０の線膨張係数は、１０ｐｐｍ／Ｋ〜１００ｐｐｍ／Ｋ程度である。また、枠体２０を成形樹脂で形成することにより、ガラスよりも耐衝撃性に優れ、軽量且つ複雑な曲部や孔部を有する形状を容易に形成することができる。   On the other hand, the frame 20 uses a translucent member, for example, a part thereof is colored. For example, the frame 20 is formed by filling a mold with a thermoplastic resin. For example, the frame 20 is formed of polycarbonate (PC) or polymethyl methacrylate (PMMA). In addition to the thermoplastic resin, it is possible to use a thermosetting resin or a photocurable resin for the frame 20. The linear expansion coefficient of the frame 20 is about 10 ppm / K to 100 ppm / K. Moreover, by forming the frame body 20 from a molding resin, it is possible to easily form a shape that is superior in impact resistance to glass and that has a light and complicated curved portion or hole portion.

接着部材３０は可視光を透過する透明樹脂であることが好ましい。接着部材３０に可視光を透過する透明タイプの樹脂を用いれば、ガラス部材１１との境界が目立たず、ほとんど一体化して透光性の領域を形成でき、目視で透明なガラス複合体とすることができる。さらに透明樹脂の枠体２０と組み合わせたときは、全体が透明なガラス複合体１０とすることができる。ただし後述するように、例えば加飾領域が、接着部材３０の位置にまでかかる場合には、接着部材３０が透光性でなくてもよく、材質としては透明樹脂に限定されない。加飾領域（非透光性領域）の形成は、印刷等によって行うことができる。   The adhesive member 30 is preferably a transparent resin that transmits visible light. If a transparent resin that transmits visible light is used for the adhesive member 30, the boundary with the glass member 11 is inconspicuous and can be almost integrated to form a light-transmitting region, and a transparent glass composite is formed visually. Can do. Further, when combined with the transparent resin frame 20, the entire glass composite 10 can be obtained. However, as will be described later, for example, when the decoration region extends to the position of the adhesive member 30, the adhesive member 30 may not be translucent, and the material is not limited to transparent resin. The decoration region (non-translucent region) can be formed by printing or the like.

また、接着部材３０に１液性の常温硬化型接着剤である紫外線硬化型の樹脂を用いることが好ましい。紫外線硬化型の樹脂は短時間で硬化でき、接着時の温度変化や体積収縮が少ないため残留応力が小さい。また、ガラス部材１１と枠体２０とを接着する工程が簡単であり、量産性に優れている。また、常温硬化型のほか、熱硬化併用型の紫外線硬化樹脂を用いることができる。低収縮・低応力であれば接着時の残留応力が小さいので、ウレタン系、アクリル系、エポキシ系などの熱硬化併用型の紫外線硬化樹脂を使用できる。   Further, it is preferable to use an ultraviolet curable resin which is a one-component room temperature curable adhesive for the adhesive member 30. The UV curable resin can be cured in a short time and has little residual stress because of little temperature change and volume shrinkage during bonding. Moreover, the process of bonding the glass member 11 and the frame body 20 is simple, and the mass productivity is excellent. In addition to the room temperature curable type, a thermosetting UV curable resin can be used. If the shrinkage is low and the stress is low, the residual stress at the time of adhesion is small, and therefore, a thermosetting UV curable resin such as urethane, acrylic or epoxy can be used.

And a fourth side surface 11f that connects the fourth back edge portion 11b4 of the back surface 11b.

本実施形態ではガラス部材１１が平板状とされている。ただしガラス部材１１の表面１１ａが加工により凸型の湾曲面状となっていたり、凹型の湾曲面状となっていてもよい。   In the present embodiment, the glass member 11 has a flat plate shape. However, the surface 11a of the glass member 11 may have a convex curved surface shape by processing, or may have a concave curved surface shape.

なお、ガラス部材１１の表面１１ａは、入力装置１の入力操作面１ａを構成する（図４（ａ）（ｂ）参照）。   In addition, the surface 11a of the glass member 11 comprises the input operation surface 1a of the input device 1 (refer FIG. 4 (a) (b)).

図１（ａ）（ｂ）に示すように、各側面１１ｃ〜１１ｆは第１の傾斜角θ１を備える第１の傾斜面１３で形成される。ここで第１の傾斜角θ１は、裏面１１ｂからの傾き角度で示される。図１（ｂ）に示すようにガラス部材１１の縦断面は台形状となっている。   As shown in FIGS. 1A and 1B, each of the side surfaces 11c to 11f is formed by a first inclined surface 13 having a first inclination angle θ1. Here, the first inclination angle θ1 is indicated by an inclination angle from the back surface 11b. As shown in FIG.1 (b), the vertical cross section of the glass member 11 is trapezoid shape.

図１（ｃ）（ｄ）に示すように枠体２０は厚さ方向（Ｚ）に対向する表面２０ａと裏面２０ｂとを備え、厚さ方向（Ｚ）に一定の厚さ寸法を有する。   As shown in FIGS. 1C and 1D, the frame body 20 includes a front surface 20a and a back surface 20b facing each other in the thickness direction (Z), and has a certain thickness dimension in the thickness direction (Z).

枠体２０には、その中央に上面２０ａから下面２０ｂに貫通する貫通孔２１が形成されている。貫通孔２１の表面２０ａ側の周囲には、Ｘ１−Ｘ２方向に平行でＹ１側に形成された第１表縁部２０ａ１と、Ｘ１−Ｘ２方向に平行でＹ２側に形成された第２表縁部２０ａ２と、Ｙ１−Ｙ２方向に平行でＸ１側に形成され、第１表縁部２０ａ１と第２表縁部２０ａ２間を繋ぐ第３表縁部２０ａ３と、Ｙ１−Ｙ２方向に平行でＸ２側に形成され、第１表縁部２０ａ１と第２表縁部２０ａ２間を繋ぐ第４表縁部２０ａ４と、を備える。   The frame body 20 is formed with a through-hole 21 penetrating from the upper surface 20a to the lower surface 20b at the center thereof. Around the surface 20a side of the through hole 21, a first surface edge portion 20a1 formed on the Y1 side parallel to the X1-X2 direction and a second surface edge formed on the Y2 side parallel to the X1-X2 direction Part 20a2, parallel to the Y1-Y2 direction and formed on the X1 side, the third surface edge part 20a3 connecting the first surface edge part 20a1 and the second surface edge part 20a2, and the X2 side parallel to the Y1-Y2 direction And a fourth surface edge portion 20a4 connecting the first surface edge portion 20a1 and the second surface edge portion 20a2.

そして、貫通孔２１の周囲には、表面２０ａの第１表縁部２０ａ１と裏面２０ｂの第１裏縁部２０ｂ１間を繋ぐ第１側壁部２０ｃと、表面２０ａの第２表縁部２０ａ２と裏面２０ｂの第２裏縁部２０ｂ２間を繋ぐ第２側壁部２０ｄと、表面２０ａの第３表縁部２０ａ３と裏面２０ｂの第３裏縁部２０ｂ３間を繋ぐ第３側壁部２０ｅと、表面２０ａの第４表縁部２０ａ４と裏面２０ｂの第４裏縁部２０ｂ４間を繋ぐ第４側壁部２０ｆを備える。   Around the through hole 21, there are a first side wall portion 20c connecting the first front edge portion 20a1 of the front surface 20a and the first back edge portion 20b1 of the back surface 20b, and a second front edge portion 20a2 of the front surface 20a and the back surface. A second side wall portion 20d connecting the second back edge portions 20b2 of the 20b, a third side wall portion 20e connecting the third front edge portion 20a3 of the front surface 20a and the third back edge portion 20b3 of the back surface 20b, and a surface 20a A fourth side wall portion 20f that connects the fourth front edge portion 20a4 and the fourth back edge portion 20b4 of the back surface 20b is provided.

図１（ｃ）（ｄ）に示すように各側壁部２０ｃ〜２０ｆは第２の傾斜角θ２を備える第２の傾斜面１４で形成される。ここで第２の傾斜角θ２は、貫通孔２１の下面２０ｂからの傾き角度で示される。   As shown in FIGS. 1C and 1D, each of the side wall portions 20c to 20f is formed by a second inclined surface 14 having a second inclination angle θ2. Here, the second inclination angle θ <b> 2 is indicated by an inclination angle from the lower surface 20 b of the through hole 21.

本実施形態では、第１の傾斜角θ１と第２の傾斜角θ２は異なる値であり、第１の傾斜角θ１＞第２の傾斜角θ２となっている。すなわち第１の傾斜角θ１のほうが急で、第２の傾斜角θ２のほうが緩やかである。   In the present embodiment, the first inclination angle θ1 and the second inclination angle θ2 are different values, and the first inclination angle θ1> the second inclination angle θ2. That is, the first inclination angle θ1 is steeper and the second inclination angle θ2 is gentler.

傾斜角θ１，θ２は限定されないが、例えば第１の傾斜角θ１は、４５°程度、第２の傾斜角θ２は２５°程度に調整される。   Although the inclination angles θ1 and θ2 are not limited, for example, the first inclination angle θ1 is adjusted to about 45 °, and the second inclination angle θ2 is adjusted to about 25 °.

ここで、図１（ａ）（ｂ）に示すガラス部材１１の表面１１ａの大きさは、図１（ｃ）（ｄ）に示す枠体２０の貫通孔２１の表面２０ａ側の大きさよりもやや小さくされている。このため、図２や図３に示すように、ガラス部材１１の各側面１１ｃ〜１１ｆと表面１１ａとの間の各表縁部１１ａ１〜１１ａ４と、枠体２０の各側壁部２０ｃ〜２０ｆと貫通孔２１の周囲に位置する表面２０ａとの間の各表縁部２０ａ１〜２０ａ４の間には、ギャップＧが形成されている。   Here, the size of the surface 11a of the glass member 11 shown in FIGS. 1 (a) and 1 (b) is slightly larger than the size of the through hole 21 of the frame body 20 shown in FIGS. 1 (c) and 1 (d) on the surface 20a side. It has been made smaller. For this reason, as shown in FIG.2 and FIG.3, each side edge part 11a1-11a4 between each side surface 11c-11f and the surface 11a of the glass member 11, and each side wall part 20c-20f of the frame 20, and penetration A gap G is formed between each of the front edge portions 20a1 to 20a4 between the surface 20a located around the hole 21.

また上記した傾斜角θ１，θ２の違いにより、ガラス部材１１の裏面１１ｂと各側面１１ｃ〜１１ｆとの間の各裏縁部１１ｂ１〜１１ｂ４と、枠体２０の各側壁部２０ｃ〜２０ｆと貫通孔２１の周囲に位置する裏面２０ｂとの間の各裏縁部２０ｂ１〜２０ｂ４の間に形成された空間幅ｔ２は、表面側のギャップＧのギャップ寸法ｔ１よりも大きく形成されている。このため図３や図４に示すように、ガラス部材１１の各側面１１ｃ〜１１ｆと枠体２０の各側壁部２０ｃ〜２０ｆとの間に形成された隙間４０は、裏面側から表面側に向けて徐々に先細る形状とされている。   Further, due to the difference between the inclination angles θ1 and θ2, the back edge portions 11b1 to 11b4 between the back surface 11b of the glass member 11 and the side surfaces 11c to 11f, the side wall portions 20c to 20f of the frame body 20, and the through holes. The space width t2 formed between the back edge portions 20b1 to 20b4 between the back surface 20b and the back surface 20b located around the periphery 21 is formed larger than the gap dimension t1 of the gap G on the front surface side. Therefore, as shown in FIG. 3 and FIG. 4, the gap 40 formed between each side surface 11 c to 11 f of the glass member 11 and each side wall portion 20 c to 20 f of the frame body 20 is directed from the back surface side to the front surface side. The shape is gradually tapered.

図１（ｃ）（ｄ）では、枠体２０の貫通孔２１の周囲に広がる表面２０ａ及び裏面２０ｂは共にＸ−Ｙ平面に平行な面となっているが、例えば表面２０ａを曲面状で形成することも可能である。   In FIGS. 1C and 1D, the front surface 20a and the rear surface 20b extending around the through hole 21 of the frame 20 are both parallel to the XY plane. For example, the front surface 20a is formed in a curved shape. It is also possible to do.

本実施形態では、図１（ａ）（ｂ）に示すように、ガラス部材１１の隣り合う各側面１１ｃ〜１１ｆ間が、厚さ方向（Ｚ）の表面１１ａから裏面１１ｂにわたって平面視で略円弧状の円弧状コーナー部１５〜１８で構成されている。ここで「略円弧」としたのは、製造誤差等で多少正確な円弧でない場合も含むことを意味する。   In this embodiment, as shown to FIG. 1 (a) (b), between each adjacent side surfaces 11c-11f of the glass member 11 is substantially circular by planar view from the surface 11a of the thickness direction (Z) to the back surface 11b. It consists of arcuate arcuate corners 15-18. Here, “substantially circular arc” means that a case where the circular arc is not somewhat accurate due to a manufacturing error or the like is included.

図１（ａ）（ｂ）に示すように第１側面１１ｃと第３側面１１ｅとの間の境界部（稜線、角部）に第１の円弧状コーナー部１５が形成される。ここで第１の円弧状コーナー部１５は、図１（ａ）や図２（ａ）（ｂ）に示すように表面１１ａ側や裏面１１ｂ側からみて略円弧状であり、さらに、表面１１ａから裏面１１ｂ間の厚さ内の全域にて、略円弧状となっている。「表面１１ａから裏面１１ｂにわたって平面視で略円弧状の円弧状コーナー部１５〜１８で構成される」とは、表面１１ａ側や裏面１１ｂ側からみて略円弧状であるとともに、図２（ｃ）に示すように図３のＤ−Ｄ線に沿って切断し矢印方向から見た平面断面において、略円弧状であることを指す。ここで「平面断面」とは、厚さ寸法内においてＸＹ平面と平行な面方向から切断し表面側から見た断面を指す。したがって図２（ｃ）はある一つの平面断面を示したものであり、本実施形態では、厚さ範囲内のどの位置から切断しても、その際に現れる平面断面ではコーナー部が円弧状となっている。図２（ｃ）に示す隙間４０の空間幅ｔ５は、図２（ａ）のギャップ寸法ｔ１より大きく図２（ｂ）の空間幅ｔ２より小さい。   As shown in FIGS. 1A and 1B, a first arcuate corner portion 15 is formed at a boundary portion (ridge line, corner portion) between the first side surface 11c and the third side surface 11e. Here, as shown in FIGS. 1A and 2A and 2B, the first arcuate corner portion 15 is substantially arcuate when viewed from the front surface 11a side and the back surface 11b side, and further from the front surface 11a. In the whole area within the thickness between the back surfaces 11b, it has a substantially arc shape. “It is composed of arcuate corner portions 15 to 18 having a substantially arc shape in plan view from the front surface 11a to the back surface 11b” is substantially arc-shaped when viewed from the front surface 11a side and the back surface 11b side, and FIG. As shown in FIG. 3, the cross section taken along the line D-D in FIG. Here, the “plane cross section” refers to a cross section cut from a plane direction parallel to the XY plane and viewed from the surface side within the thickness dimension. Accordingly, FIG. 2C shows a certain plane cross section, and in this embodiment, the corner portion has an arc shape in the plane cross section that appears at any position within the thickness range, even if cut from any position within the thickness range. It has become. The space width t5 of the gap 40 shown in FIG. 2 (c) is larger than the gap dimension t1 in FIG. 2 (a) and smaller than the space width t2 in FIG. 2 (b).

また、図１、図３に示すように、第１の円弧状コーナー部１５は、第１の円弧状コーナー部１５近傍に位置する厚さ方向（Ｚ）に平行な方向を軸Ｏ１とした同心円の略円弧状で形成される。   As shown in FIGS. 1 and 3, the first arcuate corner portion 15 is a concentric circle whose axis O1 is a direction parallel to the thickness direction (Z) located in the vicinity of the first arcuate corner portion 15. It is formed in a substantially arc shape.

すなわち図３に示すように、第１の円弧状コーナー部１５は、ガラス部材１１の表面１１ａでは軸Ｏ１から円弧半径ｒ１で形成された円弧状で形成されており、ガラス部材１１の裏面１１ｂでは軸Ｏ１から円弧半径ｒ２で形成された円弧状で形成されている。表面１１ａと裏面１１ｂとの間においては、第１の傾斜面１３の傾斜角θ１に従って、表面１１ａ側から裏面１１ｂ側に向けて徐々に円弧半径ｒ３が大きくなる円弧状に形成される。   That is, as shown in FIG. 3, the first arcuate corner portion 15 is formed in an arc shape formed with an arc radius r1 from the axis O1 on the front surface 11a of the glass member 11, and on the back surface 11b of the glass member 11. It is formed in an arc shape formed with an arc radius r2 from the axis O1. Between the front surface 11a and the back surface 11b, it is formed in an arc shape in which the arc radius r3 gradually increases from the front surface 11a side to the back surface 11b side according to the inclination angle θ1 of the first inclined surface 13.

上記では、第１の円弧状コーナー部１５のみ説明したが、第２の円弧状コーナー部１６〜第４の円弧状コーナー部１８においても同じである。すなわち第２の円弧状コーナー部１６〜第４の円弧状コーナー部１８は、各円弧状コーナー部１６〜１８近傍に位置する厚さ方向（Ｚ）に平行な方向を軸Ｏ２〜Ｏ４とした同心円の円弧で形成される。   Although only the first arc-shaped corner portion 15 has been described above, the same applies to the second arc-shaped corner portion 16 to the fourth arc-shaped corner portion 18. That is, the second arcuate corner portion 16 to the fourth arcuate corner portion 18 are concentric circles whose axes O2 to O4 are parallel to the thickness direction (Z) located in the vicinity of the arcuate corner portions 16 to 18. The arc is formed.

また本実施形態では、図１（ｃ）（ｄ）に示すように、枠体２０の貫通孔２１の周囲にて隣り合う各側壁部２０ｃ〜２０ｆ間が、厚さ方向（Ｚ）の表面２０ａから裏面２０ｂにかけて平面断面が略円弧状の円弧状コーナー部２５〜２８で構成されている。ここで「略円弧」としたのは、製造誤差等で多少正確な円弧でない場合も含むことを意味する。   Moreover, in this embodiment, as shown to FIG.1 (c) (d), between each side wall part 20c-20f adjacent to the circumference | surroundings of the through-hole 21 of the frame 20, the surface 20a of thickness direction (Z). The plane cross section is constituted by arcuate corner portions 25 to 28 having a substantially arcuate shape from the rear surface 20b to the rear surface 20b. Here, “substantially circular arc” means that a case where the circular arc is not somewhat accurate due to a manufacturing error or the like is included.

図１（ｃ）（ｄ）に示すように第１側壁部２０ｃと第３側壁部２０ｅとの間の境界部（稜線、角部）に第１の円弧状コーナー部２５が形成される。第１の円弧状コーナー部２５は、図１や図２に示すように表面２０ａ側や裏面２０ｂ側からみて略円弧状で形成される。また表面２０ａから裏面２０ｂ間の厚さ内の全域にて、第１の円弧状コーナー部２５ではＸＹ平面と平行な面方向からの断面が略円弧状となっている。図１、図３に示すように、第１の円弧状コーナー部２５は、第１の円弧状コーナー部２５近傍に位置する厚さ方向（Ｚ）に平行な方向を軸Ｏ１とした同心円の略円弧状で形成される。   As shown in FIGS. 1C and 1D, a first arcuate corner portion 25 is formed at a boundary portion (ridge line, corner portion) between the first side wall portion 20c and the third side wall portion 20e. As shown in FIGS. 1 and 2, the first arc-shaped corner portion 25 is formed in a substantially arc shape when viewed from the front surface 20a side or the back surface 20b side. Further, in the entire region within the thickness between the front surface 20a and the back surface 20b, the first arc-shaped corner portion 25 has a substantially arc-shaped cross section from the plane direction parallel to the XY plane. As shown in FIGS. 1 and 3, the first arcuate corner portion 25 is a substantially concentric circle whose axis O1 is a direction parallel to the thickness direction (Z) located in the vicinity of the first arcuate corner portion 25. It is formed in an arc shape.

すなわち図３に示すように、第１の円弧状コーナー部２５は、枠体２０の表面２０ａでは軸Ｏ１から円弧半径ｒ４で形成された円弧状で形成されており、枠体２０の裏面２０ｂでは軸Ｏ１から円弧半径ｒ５で形成された円弧状で形成されている。表面２０ａと裏面２０ｂとの間においては、第２の傾斜面１４の傾斜角θ２に従って、表面２０ａ側から裏面２０ｂ側に向けて徐々に円弧半径ｒ６が大きくなる円弧状に形成される。   That is, as shown in FIG. 3, the first arc-shaped corner portion 25 is formed in an arc shape formed from the axis O1 to the arc radius r4 on the front surface 20a of the frame body 20, and on the back surface 20b of the frame body 20 It is formed in an arc shape formed with an arc radius r5 from the axis O1. Between the front surface 20a and the back surface 20b, the arc radius r6 gradually increases from the front surface 20a side to the back surface 20b side according to the inclination angle θ2 of the second inclined surface 14.

上記では、第１の円弧状コーナー部２５のみ説明したが、第２の円弧状コーナー部２６〜第４の円弧状コーナー部２８においても同じである。すなわち第２の円弧状コーナー部２６〜第４の円弧状コーナー部２８は、各円弧状コーナー部２６〜２８近傍に位置する厚さ方向（Ｚ）に平行な方向を軸Ｏ２〜Ｏ４とした同心円の円弧で形成される。   Although only the first arc-shaped corner portion 25 has been described above, the same applies to the second arc-shaped corner portion 26 to the fourth arc-shaped corner portion 28. That is, the second arcuate corner part 26 to the fourth arcuate corner part 28 are concentric circles whose axes O2 to O4 are parallel to the thickness direction (Z) located in the vicinity of each arcuate corner part 26 to 28. The arc is formed.

図３に示すように、ガラス部材１１側に形成された第１の円弧状コーナー部１５を構成する円弧半径ｒ１〜ｒ３と、枠体２０側に形成された第１の円弧状コーナー部２５を構成する円弧半径ｒ４〜ｒ６とを対比すると、同じ厚さ位置において、円弧半径ｒ４〜ｒ６＞円弧半径ｒ１〜ｒ３の関係となっている。他の円弧状コーナー部１６〜１８，２６〜２８においても同じである。   As shown in FIG. 3, arc radii r1 to r3 constituting the first arcuate corner portion 15 formed on the glass member 11 side and the first arcuate corner portion 25 formed on the frame body 20 side When the arc radii r4 to r6 are compared, the arc radii r4 to r6> the arc radii r1 to r3 at the same thickness position. The same applies to the other arc-shaped corner portions 16 to 18 and 26 to 28.

また、図１，図３に示すように、ガラス部材１１の第１の円弧状コーナー部１５と、枠体２０の第１の円弧状コーナー部２５とは、同じ軸Ｏ１を中心軸とした同心円の円弧で構成されている。また、第２の円弧状コーナー部１６，２６同士、第３の円弧状コーナー部１７，２７同士、及び、第４の円弧状コーナー部１８，２８同士についても夫々、同じ軸Ｏ２〜Ｏ４を中心軸とした同心円の円弧で構成される。   As shown in FIGS. 1 and 3, the first arcuate corner portion 15 of the glass member 11 and the first arcuate corner portion 25 of the frame body 20 are concentric circles having the same axis O1 as a central axis. It is composed of arcs. The second arcuate corner portions 16, 26, the third arcuate corner portions 17, 27, and the fourth arcuate corner portions 18, 28 are also centered on the same axis O2 to O4. Consists of concentric arcs as axes.

そして本実施形態では、ガラス部材１１の各側面１１ｃ〜１１ｆと、枠体２０の各側壁部２０ｃ〜２０ｆとの間、及びガラス部材１１の各円弧状コーナー部１５〜１８と枠体２０の各円弧状コーナー部２５〜２８との間に形成された隙間４０に接着部材３０が充填されて、ガラス部材１１と枠体２０間が接合されている（図２、図３、図４参照）。   And in this embodiment, between each side surface 11c-11f of the glass member 11, and each side wall part 20c-20f of the frame 20, and each arc-shaped corner part 15-18 of the glass member 11, and each of the frame 20 The gap member 40 formed between the arcuate corner portions 25 to 28 is filled with the adhesive member 30, and the glass member 11 and the frame body 20 are joined (see FIGS. 2, 3, and 4).

本実施形態では、図１〜図４に示すようにガラス部材１１の各側面１１ｃ〜１１ｆと枠体２０の各側壁部２０ｃ〜２０ｆとを、その間の隙間４０が表面側に向けて徐々に先細る形状となる傾斜面１３，１４で形成している。   In this embodiment, as shown in FIGS. 1 to 4, the side surfaces 11 c to 11 f of the glass member 11 and the side wall portions 20 c to 20 f of the frame body 20 are gradually tapered with the gap 40 therebetween facing the surface side. It forms with the inclined surfaces 13 and 14 used as a shape.

さらに本実施形態では、隣り合う各側面１１ｃ〜１１ｆ間、及び隣り合う各側壁部２０ｃ〜２０ｆ間を、夫々、厚さ方向（Ｚ）の表面から裏面にかけて略円弧状の平面断面を備える円弧状コーナー部１５〜１８、２５〜２８で構成した。これにより、線膨張係数の異なるガラス部材１１と枠体２０との間の接合部分に生じる剥離応力（内部残留応力）を効果的に小さくできる。なお後述するシミュレーションでは、剥離応力を接着部材３０とガラス部材１１との間のコーナー部での剥離応力として評価した。   Further, in the present embodiment, an arc shape having a substantially arc-shaped planar cross section between the adjacent side surfaces 11c to 11f and the adjacent side wall portions 20c to 20f from the front surface to the back surface in the thickness direction (Z), respectively. It comprised with the corner parts 15-18, 25-28. Thereby, the peeling stress (internal residual stress) which arises in the junction part between the glass member 11 and the frame 20 from which a linear expansion coefficient differs can be made small effectively. In the simulation described later, the peel stress was evaluated as the peel stress at the corner between the adhesive member 30 and the glass member 11.

また後述のシミュレーションでも示すように、本実施形態では、ガラス部材１１の各側面１１ｃ〜１１ｆ及び枠体２０の各側壁部２０ｃ〜２０ｆを傾斜面１３，１４で形成したことで、各側面及び各側壁部を垂直面とした従来例に比べてガラス部材１１と枠体２０との接合部分に作用する剥離応力を効果的に低減でき、加えて、本実施形態では、ガラス部材１１の隣り合う各側面１１ｃ〜１１ｆ間、及び枠体２０の隣り合う各側壁部２０ｃ〜２０ｆを円弧状コーナー部１５〜１８，２５〜２８としたことで、コーナー部を円弧状とせず角張る形状とした比較例と比べて、剥離応力を低減でき、特に、接合部分の接着領域が狭まる表面付近での剥離応力を効果的に緩和することができる。   Moreover, as shown also in the simulation mentioned later, in this embodiment, by forming each side surface 11c-11f of the glass member 11 and each side wall part 20c-20f of the frame 20 with the inclined surfaces 13 and 14, each side surface and each each Compared to the conventional example in which the side wall portion is a vertical surface, the peeling stress acting on the joint portion between the glass member 11 and the frame body 20 can be effectively reduced. In addition, in the present embodiment, each of the adjacent glass members 11 is adjacent to each other. A comparative example in which the side walls 11c to 11f and the adjacent side wall parts 20c to 20f of the frame 20 are arcuate corner parts 15 to 18 and 25 to 28, so that the corner parts are not arcuate and have an angular shape. As compared with the above, it is possible to reduce the peeling stress, and in particular, it is possible to effectively relieve the peeling stress in the vicinity of the surface where the bonding region of the joint portion is narrowed.

図６に示す部分平面図（ガラス複合体を表面側からみた一部）は、別の実施形態を示すものであり、図６では、ガラス部材１１の円弧状コーナー部３３と、枠体２０の円弧状コーナー部３４とを同じ円弧半径で形成している。このような構成も実施形態の一例であるが、内側に位置するガラス部材１１の円弧状コーナー部３３と、外側に位置する枠体２０の円弧状コーナー部３４とを同じ円弧半径とすると、図６に示すように、ガラス部材１１と枠体２０との間に広い空間幅ｔ３と、空間幅ｔ３よりも狭まる空間幅ｔ４が生じ、これら空間幅ｔ３，ｔ４の差が大きくなりやすい。このため、接着部材３０が隙間４０の全域にスムースに流入せず、接着部材３０のない空隙部分ができやすいなど接合状態が不安定になることがある。   The partial plan view shown in FIG. 6 (a part of the glass composite viewed from the surface side) shows another embodiment. In FIG. 6, the arcuate corner portion 33 of the glass member 11 and the frame body 20 are shown. The arcuate corner portion 34 is formed with the same arc radius. Such a configuration is also an example of the embodiment. However, when the arcuate corner portion 33 of the glass member 11 located on the inner side and the arcuate corner portion 34 of the frame body 20 located on the outer side have the same arc radius, FIG. As shown in FIG. 6, a wide space width t3 and a space width t4 narrower than the space width t3 are generated between the glass member 11 and the frame body 20, and the difference between the space widths t3 and t4 tends to increase. For this reason, the bonding member 30 may not flow smoothly over the entire gap 40, and the bonding state may become unstable, for example, a void portion without the bonding member 30 may be easily formed.

よって、図１〜図３に示すように、枠体２０側の各円弧状コーナー部２５〜２８を、ガラス部材１１側の各円弧状コーナー部１５〜１８よりも大きい半径の円弧状で形成することが好ましい。これにより、ガラス部材１１の各円弧状コーナー部１５〜１８と枠体２０の各円弧状コーナー部２５〜２８との間の隙間４０から各側面１１ｃ〜１１ｆと各側壁部２０ｃ〜２０ｆ間の隙間４０にかけて略一定間隔にでき、剥離応力の低減を図るとともに接着部材３０をガラス部材１１と枠体２０との間の隙間４０に適切に充填でき、良好な接合状態を保つことができる。   Accordingly, as shown in FIGS. 1 to 3, the arc-shaped corner portions 25 to 28 on the frame body 20 side are formed in an arc shape having a larger radius than the arc-shaped corner portions 15 to 18 on the glass member 11 side. It is preferable. Thereby, the clearance gap between each side surface part 11c-11f and each side wall part 20c-20f from the clearance gap 40 between each arcuate corner part 15-18 of the glass member 11, and each arcuate corner part 25-28 of the frame 20 is demonstrated. 40, the separation stress can be reduced and the adhesive member 30 can be appropriately filled in the gap 40 between the glass member 11 and the frame body 20, and a good bonded state can be maintained.

また本実施形態では、例えばガラス部材１１の各円弧状コーナー部１５〜１８を、表面１１ａから裏面１１ｂにかけて図３に示す一定の円弧半径ｒ１で形成し、枠体２０の各円弧状コーナー部２５〜２８を、表面２０ａから裏面２０ｂにかけて図３に示す一定の円弧半径ｒ１やｒ４で形成することもできるが、図３に示すように、各円弧状コーナー部１５，２５（１６〜１８、２６〜２８）を、表面から裏面にかけて厚さ方向（Ｚ）に平行な軸Ｏ１を中心軸とした同心円の円弧で形成することで、効果的に剥離応力（内部残留応力）を低減できる。   In the present embodiment, for example, the arc-shaped corner portions 15 to 18 of the glass member 11 are formed from the front surface 11a to the back surface 11b with the constant arc radius r1 shown in FIG. Can be formed with the constant arc radii r1 and r4 shown in FIG. 3 from the front surface 20a to the back surface 20b. However, as shown in FIG. 3, the arc-shaped corner portions 15, 25 (16-18, 26) are formed. ˜28) are formed by concentric circular arcs with the axis O1 parallel to the thickness direction (Z) from the front surface to the back surface as the central axis, the peeling stress (internal residual stress) can be effectively reduced.

また、図３に示したような同心円の円弧状とせず、ガラス部材１１側の各円弧状コーナー部１５〜１８及び、枠体２０側の各円弧状コーナー部２５〜２８を表面から裏面にかけて徐々に円弧半径が大きくなるように形成することも可能であるが、図３に示す各円弧状コーナー部を表面から裏面にかけて同心円の円弧状で形成することで、効果的に円弧状コーナー部での剥離応力を低減できるとともに加工がしやすくなり、生産コストの低減を図ることができる。   Further, the concentric circular arcs as shown in FIG. 3 are not formed, but the respective arc-shaped corner portions 15 to 18 on the glass member 11 side and the respective arc-shaped corner portions 25 to 28 on the frame body 20 side are gradually formed from the front surface to the back surface. 3 can be formed so that the arc radius becomes large, but by forming each arc corner portion shown in FIG. 3 in a concentric arc shape from the front surface to the back surface, the arc corner portion can be effectively formed. Peeling stress can be reduced and processing can be facilitated, and production costs can be reduced.

また、ガラス部材１１側の各円弧状コーナー部１５〜１８を同心円の円弧状で形成するための軸Ｏ１〜Ｏ４と、枠体２０側の各円弧状コーナー部２５〜２８を同心円の円弧状で形成するための軸Ｏ１〜Ｏ４とが、多少、平面方向にずれた状態であってもよい。ただし、外側に位置する枠体２０の各円弧状コーナー部２５〜２８の円弧半径のほうが、内側に位置するガラス部材１１の各円弧状コーナー部１５〜１８の円弧半径よりも大きくなるように設定する。   Further, the axes O1 to O4 for forming the arcuate corner portions 15 to 18 on the glass member 11 side in a concentric arc shape, and the arcuate corner portions 25 to 28 on the frame 20 side in a concentric arc shape. The axes O1 to O4 for formation may be slightly shifted in the plane direction. However, the arc radii of the arcuate corner portions 25 to 28 of the frame body 20 located on the outside are set to be larger than the arc radii of the arcuate corner portions 15 to 18 of the glass member 11 located on the inside. To do.

また本実施形態では、図２、図３に示すように、ガラス部材１１の各表縁部１１ａ１〜１１ａ４と、枠体２０の貫通孔２１の各表縁部２０ａ１〜２０ａ４との間にギャップＧが形成されていることが好ましい。これにより、各側面１１ｃ〜１１ｆと、各側壁部２０ｃ〜２０ｆとの間が表面側にて接触した状態よりも効果的に剥離応力を低減させることができ、特に表面付近の接合部分にて生じる剥離応力を効果的に低減できる。   In the present embodiment, as shown in FIGS. 2 and 3, a gap G is formed between each surface edge portion 11 a 1 to 11 a 4 of the glass member 11 and each surface edge portion 20 a 1 to 20 a 4 of the through hole 21 of the frame body 20. Is preferably formed. Thereby, it is possible to reduce the peeling stress more effectively than the state in which the side surfaces 11c to 11f and the side wall portions 20c to 20f are in contact with each other on the surface side, and particularly occurs at the joint portion near the surface. The peeling stress can be effectively reduced.

また本実施形態では、ガラス部材１１の表面１１ａと枠体２０の表面２０ａとが同一面で形成されることが好ましい。例えば後述するシミュレーションで示すように、枠体２０がガラス部材１１の表面１１ａに乗り上げてしまう構成に比べて、効果的に剥離応力の低減を図ることができる。   Moreover, in this embodiment, it is preferable that the surface 11a of the glass member 11 and the surface 20a of the frame 20 are formed in the same plane. For example, as shown in a simulation described later, the peeling stress can be effectively reduced as compared with a configuration in which the frame body 20 rides on the surface 11a of the glass member 11.

図９は、図８の変形例の他の実施形態のガラス複合体１０を用いた入力装置２の模式断面図である。図９に示すようにガラス複合体１０の裏面１０ｂには、センサ部材３が設けられる。センサ部材３は例えばフィルム状の静電容量型センサである。センサ部材３とガラス複合体１０との間は、透明な粘着層を介して接合されている。センサ部材３の構成は特に限定されるものではなく、例えば透明基材の表面にＩＴＯ等からなる電極が配置された構成である。入力装置の入力操作面１ａを指等の操作体で操作すると、その操作位置（ＸＹ座標位置）は、センサ部材３の静電容量変化に基づいて、検出することが可能になっている。また枠体２０（上枠）の裏側に、枠体２０（上枠）とは別体で形成された下枠４２が設けられている。下枠４２にも枠体２０と同様に貫通孔４３が設けられているが、貫通孔４３の大きさは枠体２０に設けられた貫通孔２１よりも小さくなっている。 図９の構成により、ガラス部材１１の裏面１１ｂ、隙間４０内の接着部材３０、枠体２０（上枠）の裏面２０ｂを、センサ部材３を介して下枠４２により支持し、ガラス部材１１と枠体２０との接合強度を補強することができる。下枠４２は、粘着層を介してガラス複合体１０に接合されている。またセンサ部材３がフィルム状で形成され、ガラス部材１１の裏面１１ｂ、隙間４０内の接着部材３０、枠体２０（上枠）の裏面２０ｂにわたって形成されている場合には、ガラス部材１１と枠体２０との接合強度を補強することができる。   FIG. 9 is a schematic cross-sectional view of the input device 2 using the glass composite 10 of another embodiment of the modification of FIG. As shown in FIG. 9, the sensor member 3 is provided on the back surface 10 b of the glass composite 10. The sensor member 3 is, for example, a film-like capacitive sensor. The sensor member 3 and the glass composite 10 are joined via a transparent adhesive layer. The structure of the sensor member 3 is not specifically limited, For example, it is the structure by which the electrode which consists of ITO etc. is arrange | positioned on the surface of a transparent base material. When the input operation surface 1 a of the input device is operated with an operation body such as a finger, the operation position (XY coordinate position) can be detected based on the change in the capacitance of the sensor member 3. Further, a lower frame 42 formed separately from the frame body 20 (upper frame) is provided on the back side of the frame body 20 (upper frame). The lower frame 42 is provided with a through hole 43 as in the case of the frame body 20, but the size of the through hole 43 is smaller than that of the through hole 21 provided in the frame body 20. 9, the back surface 11b of the glass member 11, the adhesive member 30 in the gap 40, and the back surface 20b of the frame body 20 (upper frame) are supported by the lower frame 42 via the sensor member 3, and the glass member 11 The bonding strength with the frame body 20 can be reinforced. The lower frame 42 is joined to the glass composite 10 via an adhesive layer. When the sensor member 3 is formed in a film shape and is formed over the back surface 11b of the glass member 11, the adhesive member 30 in the gap 40, and the back surface 20b of the frame 20 (upper frame), the glass member 11 and the frame are formed. The bonding strength with the body 20 can be reinforced.

ガラス複合体１０の製造方法について図１０を用いて説明する。
まず、図１（ｃ）（ｄ）に示す枠体２０を上下１８０度、反転させた状態で（すなわち表面２０ａを下側、裏面２０ｂを上側として）、図１０に示す受け台９７の平坦面９７ａ上に設置する。このため、受け台９７上に枠体２０を設置した状態では、枠体２０の貫通孔２１は下面側から上面側に向けて徐々に広がっている。 The manufacturing method of the glass composite 10 is demonstrated using FIG.
First, in a state where the frame body 20 shown in FIGS. 1C and 1D is inverted 180 degrees up and down (that is, the front surface 20a is the lower side and the rear surface 20b is the upper side), the flat surface of the cradle 97 shown in FIG. Install on 97a. For this reason, in a state where the frame body 20 is installed on the cradle 97, the through hole 21 of the frame body 20 gradually spreads from the lower surface side toward the upper surface side.

続いて、図１（ａ）（ｂ）に示すガラス部材１１を、枠体２０と同様に、上下１８０度、反転させた状態にして（すなわち表面１１ａを下側、裏面１１ｂを上側にして）、枠体２０の貫通孔２１内に挿入する。   Subsequently, the glass member 11 shown in FIGS. 1A and 1B is turned upside down 180 degrees in the same manner as the frame body 20 (that is, the front surface 11a is on the lower side and the back surface 11b is on the upper side). Then, it is inserted into the through hole 21 of the frame body 20.

このとき、図１を用いて説明したように、枠体２０の貫通孔２１を囲む各側壁部２０ｃ〜２０ｆの第２の傾斜角θ２は、ガラス部材１１の各側面１１ｃ〜１１ｆの第１の傾斜角θ１よりも緩やかであり、貫通孔２１がガラス部材１１よりも大きく形成されているため、ガラス部材１１を枠体２０の貫通孔２１内に無理なく挿入できる。また本実施形態であれば、ガラス部材１１の中心と枠体２０の貫通孔２１の中心とが多少ずれた状態でガラス部材１１を貫通孔２１に挿入しても、ガラス部材１１の側面が貫通孔２１の側壁部にガイドされて移動し、ガラス部材１１を貫通孔２１内に適切に挿入できる。これにより、ガラス部材１１の表面１１ａと枠体２０の表面２０ａとを同一平面に一致させることができる。   At this time, as described with reference to FIG. 1, the second inclination angle θ <b> 2 of the side wall portions 20 c to 20 f surrounding the through hole 21 of the frame body 20 is the first inclination angle of the side surfaces 11 c to 11 f of the glass member 11. Since it is gentler than the inclination angle θ1 and the through hole 21 is formed larger than the glass member 11, the glass member 11 can be inserted into the through hole 21 of the frame body 20 without difficulty. Moreover, if it is this embodiment, even if it inserts the glass member 11 in the through-hole 21 in the state in which the center of the glass member 11 and the center of the through-hole 21 of the frame 20 shifted | deviated somewhat, the side surface of the glass member 11 penetrated The glass member 11 can be guided and moved by the side wall portion of the hole 21, and can be appropriately inserted into the through hole 21. Thereby, the surface 11a of the glass member 11 and the surface 20a of the frame 20 can be made to correspond to the same plane.

ガラス部材１１の各側面１１ｃ〜１１ｆの表面側の縁部１１ａ１〜１１ａ４と、枠体２０の各側壁部２０ｃ〜２０ｆの表面側の縁部２０ａ１〜２０ａ４との間にはギャップＧが形成された状態になる（図２（ａ）、図３等参照）。また、ガラス部材１１の各側面１１ｃ〜１１ｆと、枠体２０の各側壁部２０ｃ〜２０ｆとに挟まれた隙間４０を形成でき、この隙間４０内に接着部材３０を充填することで、ガラス部材１１の各側面１１ｃ〜１１ｆと枠体２０の各側壁部２０ｃ〜２０ｆ間を接合することが出来る。   A gap G was formed between the edge portions 11a1 to 11a4 on the surface side of the side surfaces 11c to 11f of the glass member 11 and the edge portions 20a1 to 20a4 on the surface side of the side wall portions 20c to 20f of the frame body 20. It will be in a state (refer to Drawing 2 (a), Drawing 3, etc.). Moreover, the clearance gap 40 pinched | interposed between each side surface 11c-11f of the glass member 11 and each side wall part 20c-20f of the frame 20 can be formed, and the glass member is filled with the adhesive member 30 in this clearance gap 40. 11 side surfaces 11c to 11f and the side wall portions 20c to 20f of the frame body 20 can be joined.

ここで図１０に示すように、ガラス部材１１を枠体２０の貫通孔２１内に挿入する前に、接着部材３０を、予めガラス部材１１の各側面１１ｃ〜１１ｆ（あるいは枠体２０の各側壁部２０ｃ〜２０ｆ）に塗布しておいてもよいし、または、ガラス部材１１を枠体２０の貫通孔２１内に挿入した後、隙間４０内に接着部材３０を充填してもよい。   Here, as shown in FIG. 10, before the glass member 11 is inserted into the through hole 21 of the frame body 20, the adhesive member 30 is preliminarily attached to the side surfaces 11 c to 11 f of the glass member 11 (or each side wall of the frame body 20. Alternatively, the adhesive member 30 may be filled in the gap 40 after the glass member 11 is inserted into the through hole 21 of the frame body 20.

接着部材３０には、常温硬化型や熱硬化併用型の紫外線硬化樹脂を用いることができる。
よって接着部材３０の充填後、紫外線照射、あるいは紫外線照射と加熱硬化を行う。 The adhesive member 30 can be a room temperature curing type or a thermosetting combined type ultraviolet curing resin.
Therefore, after the adhesive member 30 is filled, ultraviolet irradiation, or ultraviolet irradiation and heat curing are performed.

本実施形態によれば、ガラス部材１１の各側面１１ｃ〜１１ｄ間、及び枠体２０の貫通孔２１の各側壁部２０ｃ〜２０ｆ間を、円弧状コーナー部１５〜１８，２５〜２８で構成した。これにより、各側面１１ｃ〜１１ｆと各側壁部２０ｃ〜２０ｆ間から、各円弧状コーナー部１５〜１８，２５〜２８間にかけて簡単且つ満遍なく接着部材３０を充填することができる。   According to this embodiment, between each side surface 11c-11d of the glass member 11, and between each side wall part 20c-20f of the through-hole 21 of the frame 20, it comprised with the circular-arc-shaped corner parts 15-18, 25-28. . As a result, the adhesive member 30 can be filled easily and evenly between the side surfaces 11c to 11f and the side wall portions 20c to 20f and between the arcuate corner portions 15 to 18 and 25 to 28.

特に、枠体２０側の各円弧状コーナー部２５〜２８を、ガラス部材１１側の各円弧状コーナー部１５〜１８よりも大きい半径の円弧で形成し、さらに、各円弧状コーナー部１５〜１８，２５〜２８を同心円状の円弧で形成することで、各側面１１ｃ〜１１ｆと各側壁部２０ｃ〜２０ｆ間から各円弧状コーナー部１５〜１８，２５〜２８間にかけて空間幅が急激に変化する箇所を無くすことができ、接着部材３０を隙間４０内に満遍なく流入させることができ、ガラス部材１１と枠体２０との間を接着部材３０により適切に接合することができる。   In particular, the arc-shaped corner portions 25 to 28 on the frame body 20 side are formed by arcs having a larger radius than the arc-shaped corner portions 15 to 18 on the glass member 11 side, and the arc-shaped corner portions 15 to 18 are further formed. , 25 to 28 are formed by concentric circular arcs, and the space width changes abruptly from the side surfaces 11c to 11f and the side wall portions 20c to 20f to the arc-shaped corner portions 15 to 18 and 25 to 28. The location can be eliminated, the adhesive member 30 can be evenly introduced into the gap 40, and the glass member 11 and the frame body 20 can be appropriately joined by the adhesive member 30.

（円弧状コーナー部の円弧半径の有限要素法によるシミュレーション）
まず、図１１（ａ）に示す縦断面形状のガラス複合体１０のモデルを作成し、有限要素法によるシミュレーションを行った。図１１（ａ）に示すガラス複合体１０は、図１等で示したガラス部材１１と枠体２０と、接着部材３０とで構成される。ただし図１１（ａ）では、ガラス部材１１の表面側での各表縁部Ｄと、枠体２０に形成された貫通孔２１の各表縁部Ｅとが接している。このシミュレーションでは、ガラス部材１１の各側面の傾斜角度θ１を４５°、貫通孔２１の各側壁部の傾斜角度θ２を２５°に設定した。 (Simulation of arc radius of arc corner by finite element method)
First, a model of the glass composite 10 having a longitudinal cross-sectional shape shown in FIG. A glass composite 10 shown in FIG. 11A includes the glass member 11, the frame 20, and the adhesive member 30 shown in FIG. However, in FIG. 11A, each surface edge portion D on the surface side of the glass member 11 is in contact with each surface edge portion E of the through hole 21 formed in the frame body 20. In this simulation, the inclination angle θ1 of each side surface of the glass member 11 was set to 45 °, and the inclination angle θ2 of each side wall portion of the through hole 21 was set to 25 °.

シミュレーションに使用したガラス部材１１の線膨張係数は、８ｐｐｍ／Ｋで、枠体２０の線膨張係数は、７０ｐｐｍ／Ｋであった。また、接着部材３０には硬化後の線膨張係数が１８０ｐｐｍ／Ｋのアクリル系接着剤を用いた。またガラス部材１１の縦横長さを、６０×４０ｍｍで形成し、厚さを０．７５ｍｍとした。また枠体２０の外周の縦横長さを、８０×５２ｍｍで形成し、厚さを０．７５ｍｍとした。また貫通孔２１の縦横長さを、６０×４０ｍｍとした。なお、ガラス部材、枠体及び接着部材の材質、寸法は、図１２、図１３、図１５〜図１７の全てのシミュレーションにおいて同じとした。なおギャップ寸法を変化させるシミュレーションでは、貫通孔２１の縦横長さは、６０×４０ｍｍを基本としてギャップ寸法に応じて変化させた。   The linear expansion coefficient of the glass member 11 used for the simulation was 8 ppm / K, and the linear expansion coefficient of the frame 20 was 70 ppm / K. For the adhesive member 30, an acrylic adhesive having a linear expansion coefficient after curing of 180 ppm / K was used. The length and width of the glass member 11 were 60 × 40 mm, and the thickness was 0.75 mm. Moreover, the length and width of the outer periphery of the frame body 20 were formed at 80 × 52 mm, and the thickness was set to 0.75 mm. The vertical and horizontal lengths of the through holes 21 were 60 × 40 mm. Note that the materials and dimensions of the glass member, the frame, and the adhesive member were the same in all simulations of FIGS. 12, 13, and 15 to 17. In the simulation for changing the gap size, the vertical and horizontal lengths of the through holes 21 were changed according to the gap size on the basis of 60 × 40 mm.

シミュレーションでは、図３に示す各コーナー部での円弧半径ｒ１を０ｍｍ〜１ｍｍの範囲で変化させた。なお、このシミュレーションでは、ガラス部材１１の各コーナー部１５〜１８を、表面側から裏面側まで同じ一定の円弧半径ｒ１として、０ｍｍ〜１ｍｍの範囲で変化させた。同様に、枠体２０側の各コーナー部も表面側から裏面側まで同じ一定の円弧半径ｒ１として、０ｍｍ〜１ｍｍの範囲で変化させた。なお、半径ｒ１を０ｍｍとした形態は、コーナー部が円弧状で形成されていない角張ったコーナー部であるため比較例１とし、半径ｒ１を０ｍｍよりも大きくしてコーナー部を円弧状で形成した構成を実施例とした。   In the simulation, the arc radius r1 at each corner shown in FIG. 3 was changed in the range of 0 mm to 1 mm. In this simulation, the corner portions 15 to 18 of the glass member 11 were changed from 0 mm to 1 mm as the same constant arc radius r1 from the front surface side to the back surface side. Similarly, each corner portion on the frame 20 side was also changed from 0 mm to 1 mm as the same constant arc radius r1 from the front surface side to the back surface side. The form in which the radius r1 is 0 mm is an angular corner portion in which the corner portion is not formed in an arc shape, so that it is Comparative Example 1, and the radius r1 is larger than 0 mm and the corner portion is formed in an arc shape. The configuration was taken as an example.

また比較例２として図１１（ｂ）に示すガラス複合体７０のモデルを作成し有限要素法によるシミュレーションを行った。図１１（ｂ）に示すガラス複合体７０では、ガラス部材７１の各側面と枠体７２に形成された貫通孔７３の各側壁部とが垂直面で形成されている。比較例２においても、ガラス部材７１の各側面間の各コーナー部、及び、枠体７２側の各側壁部間の各コーナー部を、０ｍｍ〜１ｍｍの範囲で変化させた円弧半径ｒ１からなる円弧状で形成した。   Further, as Comparative Example 2, a model of the glass composite 70 shown in FIG. 11B was created, and a simulation by a finite element method was performed. In the glass composite 70 shown in FIG. 11B, each side surface of the glass member 71 and each side wall portion of the through hole 73 formed in the frame body 72 are formed as vertical surfaces. Also in the comparative example 2, each corner part between each side surface of the glass member 71 and each corner part between each side wall part on the frame body 72 side is a circle formed of an arc radius r1 in a range of 0 mm to 1 mm. It was formed in an arc shape.

また図１１（ｂ）におけるガラス部材７１の各側面と枠体７２の貫通孔７３の各側壁部とは接している。   Further, each side surface of the glass member 71 in FIG. 11B is in contact with each side wall portion of the through hole 73 of the frame body 72.

シミュレーションでは、ガラス複合体１０，７０を８０℃の環境下におき、接着部材３０とガラス部材１１，７１との間であってコーナー部分に生じる剥離応力（内部残留応力）を解析した。その解析結果が図１２に示されている。   In the simulation, the glass composites 10 and 70 were placed in an environment of 80 ° C., and the peeling stress (internal residual stress) generated between the adhesive member 30 and the glass members 11 and 71 at the corner portion was analyzed. The analysis result is shown in FIG.

図１２に示す縦軸の「平均剥離応力」とは、表面側から裏面側に至る全域にて生じる剥離応力（内部残留応力：ガラスコーナー部の側面に垂直な引張残留応力）を平均化したものである。   The “average peel stress” on the vertical axis shown in FIG. 12 is an average of peel stress (internal residual stress: tensile residual stress perpendicular to the side surface of the glass corner) generated in the entire area from the front side to the back side. It is.

図１２に示すように、実施例のほうが比較例１，２に比べて効果的に剥離応力を低減できることがわかった。また、円弧状コーナー部の円弧半径ｒ１を大きくすることで比較例２においても、平均剥離応力が小さくなったが、本実施例では、同じ円弧半径ｒ１でみたときに、比較例２よりも平均剥離応力を小さくすることができた。   As shown in FIG. 12, it was found that the example can reduce the peeling stress more effectively than the comparative examples 1 and 2. Further, by increasing the arc radius r1 of the arcuate corner portion, the average peel stress was reduced also in Comparative Example 2, but in this example, when viewed at the same arc radius r1, the average was greater than that of Comparative Example 2. The peel stress could be reduced.

ただし図１２のシミュレーションでは、平均剥離応力としたため、実施例において、ガラス部材１１と接着部材３０との界面の表面付近に作用する剥離応力がどの程度であるか解析するため表面から裏面にかけて厚さ比率で２０％の範囲内における接着部材３０とガラス部材１１間の剥離応力を解析した。その解析結果が図１３に示されている。   However, since the average peel stress is used in the simulation of FIG. 12, in the example, the thickness from the front surface to the back surface is analyzed in order to analyze the extent of the peel stress acting near the surface of the interface between the glass member 11 and the adhesive member 30. The peel stress between the adhesive member 30 and the glass member 11 within a range of 20% by ratio was analyzed. The analysis result is shown in FIG.

図１３に示すように実施例において、円弧状コーナー部の円弧半径ｒ１を大きくすることで効果的に表面付近に作用する接着部材３０とガラス部材１１間の剥離応力を低減できることがわかった。   As shown in FIG. 13, it was found that the peeling stress between the adhesive member 30 and the glass member 11 acting near the surface can be effectively reduced by increasing the arc radius r1 of the arc corner portion in the example.

（ギャップ寸法のシミュレーション）
次に図１４（ａ）に示すガラス複合体６０（有限要素法によるシミュレーションのモデル１））を作成した。図１４（ａ）では、ガラス部材６１と枠体６２との間が接着部材６３により接合される。ガラス部材６１の各側面及び枠体６２の各側壁部の傾斜面の傾斜角度θ１，θ２を、夫々４５°、及び２５°とした。図１４（ａ）に示すように、ガラス部材６１の表面６１ａと枠体６２の表面６２ａとは同一面で形成される。 (Gap dimension simulation)
Next, a glass composite 60 (simulation model 1 by the finite element method) shown in FIG. In FIG. 14A, the glass member 61 and the frame body 62 are joined by the adhesive member 63. The inclination angles θ1 and θ2 of the inclined surfaces of the side surfaces of the glass member 61 and the side walls of the frame body 62 were set to 45 ° and 25 °, respectively. As shown to Fig.14 (a), the surface 61a of the glass member 61 and the surface 62a of the frame 62 are formed in the same surface.

シミュレーションでは、ガラス部材６１と枠体６２との表面側に形成されるギャップ寸法を０〜０．１ｍｍの範囲内で変化させた。   In the simulation, the gap dimension formed on the surface side of the glass member 61 and the frame body 62 was changed within a range of 0 to 0.1 mm.

またガラス部材６１の各円弧状コーナー部を表面６１ａから裏面６１ｂにかけて一定の円弧半径０．６ｍｍで形成し、枠体６２の各円弧状コーナー部を表面６２ａから裏面６２ｂにかけて一定の円弧半径０．７５ｍｍとした。   Further, each arc-shaped corner portion of the glass member 61 is formed with a constant arc radius of 0.6 mm from the front surface 61a to the back surface 61b, and each arc-shaped corner portion of the frame body 62 is formed with a constant arc radius of 0.1 mm from the front surface 62a to the back surface 62b. 75 mm.

また、図１４（ｂ）に示すガラス複合体６４（有限要素法によるシミュレーションのモデル２）は、ガラス部材６１や枠体６２の構成は図１４（ａ）に示したガラス複合体６０と同じであるが、枠体６２がガラス部材６１の表面６１ａに乗り上げた状態であり、枠体６２の表面６２ａとガラス部材６１の表面６１ａとが同一面で形成されていない。図１４（ｂ）では、乗り上げ幅を０〜０．１ｍｍの範囲としてシミュレーションを行った。また、ガラス部材６１の各円弧状コーナー部と枠体６２の各円弧状コーナー部の各円弧半径はモデル１と同様とした。なお、図１５、図１６のグラフでは横軸のギャップ寸法がマイナス値として示される。   Moreover, the glass composite 64 (simulation model 2 by the finite element method) shown in FIG. 14B is the same as the glass composite 60 shown in FIG. 14A in the configuration of the glass member 61 and the frame 62. However, the frame body 62 rides on the surface 61a of the glass member 61, and the surface 62a of the frame body 62 and the surface 61a of the glass member 61 are not formed on the same plane. In FIG. 14B, the simulation was performed with the riding width in the range of 0 to 0.1 mm. Further, the arc radii of the arc-shaped corner portions of the glass member 61 and the arc-shaped corner portions of the frame body 62 are the same as those of the model 1. In the graphs of FIGS. 15 and 16, the gap dimension on the horizontal axis is shown as a negative value.

また、図１４（ｃ）に示すガラス複合体６５（有限要素法によるシミュレーションのモデル３）は、図１１（ｂ）と同様に側面及び側壁部が垂直面とされたガラス部材６６及び枠体６７で構成される。そしてシミュレーションでは、ガラス部材６１と枠体６２との表面側に形成されるギャップ寸法を０〜０．１ｍｍの範囲内で変化させた。また、ガラス部材６１の各円弧状コーナー部と枠体６２の各円弧状コーナー部の各円弧半径はモデル１と同様とした。   Further, a glass composite 65 (simulation model 3 by the finite element method) shown in FIG. 14C is a glass member 66 and a frame 67 whose side surfaces and side walls are vertical surfaces as in FIG. 11B. Consists of. And in simulation, the gap dimension formed in the surface side of the glass member 61 and the frame 62 was changed within the range of 0-0.1 mm. Further, the arc radii of the arc-shaped corner portions of the glass member 61 and the arc-shaped corner portions of the frame body 62 are the same as those of the model 1.

図１５に示す縦軸の「平均剥離応力」とは、表面側から裏面側に至る全域にて生じる接着部材とガラス部材のコーナー部との間での剥離応力（内部残留応力：ガラスコーナー部の側面に垂直な引張残留応力）を平均化したものである。   The “average peel stress” on the vertical axis shown in FIG. 15 is the peel stress (internal residual stress: of the glass corner portion) between the adhesive member and the corner portion of the glass member that occurs in the entire region from the front side to the back side. The tensile residual stress perpendicular to the side surface is averaged.

図１５に示すように、ガラス部材６６の各側面及び枠体６７の各側壁部を垂直面としたモデル３では、モデル１に比べて剥離応力が非常に大きくなった。   As shown in FIG. 15, in the model 3 in which each side surface of the glass member 66 and each side wall portion of the frame body 67 are vertical surfaces, the peeling stress is much larger than that of the model 1.

次に、モデル１及びモデル２に対し、表面から裏面にかけて厚さ比率で２０％の範囲内における接着部材とガラス部材間の剥離応力を解析した。その解析結果が図１６に示されている。   Next, for the model 1 and the model 2, the peeling stress between the adhesive member and the glass member in the range of 20% in thickness ratio from the front surface to the back surface was analyzed. The analysis result is shown in FIG.

図１６に示すようにモデル１のほうがモデル２よりも剥離応力を低減できることがわかった。   As shown in FIG. 16, it was found that the model 1 can reduce the peeling stress more than the model 2.

このように、ガラス部材の側面及び枠体の側壁部を傾斜面で形成し、且つ、表面側にギャップＧを設けることで、接合部分での剥離応力を効果的に緩和できることがわかった。   Thus, it turned out that the peeling stress in a junction part can be relieve | moderated effectively by forming the side wall part of a glass member, and the side wall part of a frame with an inclined surface, and providing the gap G on the surface side.

（円弧状コーナー部を同心円状としたシミュレーション）
次に、図１１（ａ）に示した実施例において、図３と同様に表面側から裏面側にかけて円弧状コーナー部が同心円の円弧状となるように円弧半径を大きくした（実施例１）。シミュレーションでは図３に示す円弧半径ｒ１を０．６ｍｍとしたとき、ガラス部材１１の裏面側での円弧半径ｒ２は、１．３５ｍｍであった。 (Simulation with arc-shaped corners concentric)
Next, in the example shown in FIG. 11 (a), the arc radius was increased so that the arc-shaped corner portion became a concentric arc shape from the front surface side to the back surface side as in FIG. 3 (Example 1). In the simulation, when the arc radius r1 shown in FIG. 3 is 0.6 mm, the arc radius r2 on the back surface side of the glass member 11 is 1.35 mm.

またシミュレーションでは、図３に示すギャップ寸法を０ｍｍ〜０．２５ｍｍの範囲内で変化ささせた。ギャップ寸法により適宜、枠体２０側の円弧状コーナー部の円弧半径（図３に示す円弧半径ｒ４，ｒ５，ｒ６）を調整した。   In the simulation, the gap dimension shown in FIG. 3 was changed within the range of 0 mm to 0.25 mm. The arc radius of the arc-shaped corner portion on the frame body 20 side (arc radii r4, r5, r6 shown in FIG. 3) was appropriately adjusted according to the gap size.

また、ガラス部材１１側の円弧状コーナー部の円弧半径及び枠体２０の側の円弧状コーナー部の円弧半径を夫々、０．６ｍｍで一定にしたガラス複合体を作製した（実施例２）。   In addition, a glass composite was prepared in which the arc radius of the arc-shaped corner portion on the glass member 11 side and the arc radius of the arc-shaped corner portion on the frame body 20 side were constant at 0.6 mm (Example 2).

上記した実施例１及び実施例２を８０℃の環境下におき、ギャップ寸法を０ｍｍ〜０．１ｍｍの範囲内で変化させて、剥離応力をシミュレーションにより解析した。その解析結果が図１７に示されている。図１７での縦軸の剥離応力は、図１２で説明した平均剥離応力である。   The above Example 1 and Example 2 were placed in an environment of 80 ° C., and the gap size was changed within a range of 0 mm to 0.1 mm, and the peeling stress was analyzed by simulation. The analysis result is shown in FIG. The peel stress on the vertical axis in FIG. 17 is the average peel stress described in FIG.

図１７に示すように、ガラス部材１１及び枠体２０の円弧状コーナー部を同心円状とした実施例１とすることで、半径を一定とした実施例２に比べて平均剥離応力を小さくできることがわかった。   As shown in FIG. 17, the average peel stress can be reduced by using Example 1 in which the arcuate corners of the glass member 11 and the frame 20 are concentric, compared to Example 2 in which the radius is constant. all right.

また、実施例１において、ギャップ寸法を大きくすることで剥離応力を低減できることがわかった。   Moreover, in Example 1, it turned out that peeling stress can be reduced by enlarging a gap dimension.
