Description

【０００１】
【発明の属する技術分野】
本発明は、車両ルーフの開口部に設けられるリッドの周縁部にウエザストリップを取付ける方法に関するものである。
【０００２】
【従来の技術】
車両のルーフの一部に開口部を設け、この開口部にガラスよりなるリッドをスライド可能に取付け、駆動モータの作動により、該ガラスリッドを後方にスライドさせてルーフの開口部を開状態とし、ガラスリッドを前方にスライドさせてルーフの開口部を密閉状態とする装置は、一般にサンルーフ装置と称され、従来より多くの車両に装備されている。
【０００３】
上記のようなサンルーフ装置において、ガラスよりなるリッドの外周端縁部には、ゴム等の弾性材よりなるウエザストリップが取付けられ、該リッドの閉状態にて該リッドの外周端縁部に取付けられたウエザストリップがルーフ開口部の周縁フランジに弾接して開口部を密閉シールするようになっている。
【０００４】
上記ガラスリッドの外周端縁部へのウエザストリップの取付方法としては、例えば実開平５−８０８４５号公報に開示されているように、ガラスの周縁部分の下面に固着されるリテーナにホルダを一体的に設け、該ホルダにウエザストリップを係合させて装着する方法、或は特開平６−１９１２８０号公報に開示されているように、ガラスリッドの外周端縁部に、ウエザストリップ嵌着用の周縁溝をもった合成樹脂フレームを形成し、該合成樹脂フレームの周縁溝にウエザストリップを嵌装取付ける方法等が従来より開発されている。
【０００５】
【発明が解決しようとする課題】
上記従来のウエザストリップ取付方法のうち、ウエザストリップをホルダに係合させて取付ける方法は、リッドの外形寸法のばらつきはウエザストリップ自体の弾性変形にて吸収することになるので、リッドの外形ばらつきが弾性変形の許容代を超えるような場合には、リッド閉状態でウエザストリップとルーフ開口部の周縁フランジとの間に隙間が生じ密閉シール性が損なわれたり、或はウエザストリップが周縁フランジに強く押し付けられ過ぎて上方に凸形状に膨出し、フラッシュサーフェイス化が損なわれることがある、という課題を有している。
【０００６】
また、ガラスリッドの外周端縁部に合成樹脂フレームを形成する方法は、合成樹脂射出成形のための設備及び金型共に非常に高価である上に、車種毎に専用の金型を必要とするので、実用的には採用が非常に難しい、という課題を有している。
【０００７】
本発明は、上記のような従来の課題を解決し、密閉シール性とフラッシュサーフェイス性とを満足させると共に、取付工数とコストの低減をはかり得るウエザストリップ取付方法を提供することを目的とするものである。
【０００８】
【課題を解決するための手段】
本発明は、リッドの外周部に装着されリッド閉時のシール機能を果たすウエザストリップを、リッドの外周端面に所定の隙間ｄをもって対向するよう保持金具にてリッドに取付けることにより、リッドの外形寸法のばらつきを上記隙間ｄにて吸収できるようにした。又、上記隙間ｄは上面のみが開放され、それ以外の部分は逃がし弁機能部を介してのみ外部と連通する構成とし、上記隙間ｄ内に発泡性樹脂材料を注入し、該隙間ｄの上面を上面密閉用治具にて密閉した状態で上記発泡性樹脂材料を発泡膨張させ、該発泡膨張が進み隙間ｄ内が発泡性樹脂材料で埋まった後、余剰の発泡性樹脂材料は上記逃がし弁機能部より押し出され、その後隙間ｄ内の発泡性樹脂材料の硬化をまって上記上面密閉用治具を取り外すことにより、隙間ｄが発泡性樹脂材料にて充填され、リッドからその外周のウエザストリップにかけて良好な平坦度のフラッシュサーフェイス面が形成された完成品を得ることができるものである。
【０００９】
【発明の実施の形態】
以下、本発明の実施の形態に付き、図面を参照して説明する。
【００１０】
図１は、本発明の第１の実施例を示すもので、１はガラスよりなるリッド、２は該リッド１の周縁部分の下部に装着される保持金具であり、該保持金具２の外側端部には保持フランジ２１が上向きに折曲形成され、該保持フランジ２１にウエザストリップ３が係合保持されるようになっている。
【００１１】
ウエザストリップ３は、上記保持金具２の保持フランジ２１が嵌入係合する係合溝３１ａを有する基部３１と、該基部３１の外側に円弧形状に突出する弾接部３２と、前記基部３１の内側下部よりリッド１の下側にまわり込む下側面部３３とをもった形状にゴム等の弾性材にて一体に形成される。上記下側面部３３にはリッド１の下面に弾接するリップ部３４が上向きに突出形成されている。
【００１２】
ウエザストリップ３は、図１（Ａ）に示すように、基部３１の係合溝３１ａに保持フランジ２１を嵌入係合させることにより保持金具２に組付けられ、その状態で保持金具２をリッド１の周縁部分の下部に取付け、ウエザストリップ３の基部３１の内側面がリッド１の外周端面の外側に隙間ｄをもって対向し、基部３１の上面はリッド１の上面と同一面上に位置し、下側面部３３のリップ部３４がリッド１の下面に弾接した取付状態とする。
【００１３】
このとき、ガラスよりなるリッド１の外形寸法のばらつきは、リッド１の外周端面と基部３１の内側面との隙間ｄによって吸収することにより、ウエザストリップ３の取付状態にて弾接部３２の先端位置のばらつきはなくなる。
【００１４】
次に、図１（Ｂ）に示すように、リッド１の外周端面と基部３１との隙間ｄ内に、発泡性樹脂材料（加熱発泡性樹脂材料を含む）４を注入ノズル６にて適当量全周にわたり注入し、図１（Ｃ）に示すように、隙間ｄの上面（フラッシュサーフェイス面）を樹脂材或は金属材等よりなる上面密閉用治具５にて密閉し、発泡性樹脂材料４を発泡膨張させる。
【００１５】
発泡性樹脂材料４の発泡膨張により、図１（Ｄ）のように、上記隙間ｄ内が埋まり、更に発泡膨張が続いて隙間ｄの内部圧力が上昇すると、図１（Ｅ）に示すように、その圧力上昇によりリップ部３４が内側へ押し開かれ、そこから余剰の発泡性樹脂材料４がリッド１の下部に押し出される。
【００１６】
その後、発泡性樹脂材料４の硬化をまって上面密閉用治具５を取り外すことにより、図１（Ｆ）に示すように、隙間ｄが発泡性樹脂材料４にて充填された完成品を得ることができる。
【００１７】
上記において、リップ部３４のリッド下面への弾接部は、隙間ｄの内部圧力が所定値を超えたとき押し開かれて余剰の発泡性樹脂材料４を逃がす謂わば逃がし弁（圧力弁）としての機能を有するものであり、リップ部３４の密閉力を上面密閉用治具５による密閉力より低い値に設定しておくことにより、余剰の発泡性樹脂材料４はこのリップ部３４の弾接部からのみはみ出し、上面密閉用治具４による密閉部に発泡性樹脂材料のはみ出しによりバリが発生するようなことはなく、隙間ｄ内の圧力はほぼ設定値に保たれるので、発泡性樹脂材料４の硬化時に上面に凹み等が発生することもなく、フラッシュサーフェイス面は良好な平坦度が確保される。
【００１８】
更にまた、上記のウエザストリップ取付方法を採用すれば、リッド１の外形寸法のばらつきはほぼ完全に吸収され、リッド１の閉状態において、ウエザストリップ３の弾接部３２はルーフ開口部の周縁フランジに程よく弾接してリッド１の密閉シール性が確保されると共に、フラッシュサーフェイス性が損なわれることもなく、また汎用的な簡単な設備にて安価な製造が可能となる。
【００１９】
図２は、本発明の第２の実施例を示すもので、図１に示す第１の実施例のリップ部３４の代わりに、下側面部３３とリッド１の下面との間に絞り流路３６を設け、該絞り流路３５に余剰の発泡性樹脂材料４の逃がし弁としての機能をもたせたものである。
【００２０】
すなわち、図２においては、下側面部３３の内側端部に立上り部３５を設け、ウエザストリップ３の取付状態にて該立上り部３５の上端部がリッド１の下面に近接対向して絞り流路３６が形成される構造としたものである。
【００２１】
この例においても、図１の場合と同様に、ウエザストリップ３の取付け後、リッド１の外周端面とウエザストリップ３の基部３１との隙間ｄに発泡性樹脂材料４を注入し、隙間ｄの上面を上面密閉用部治具５で密閉した状態で発泡性樹脂材料４を発泡膨張させるものであり、そのとき余剰の発泡性樹脂材料４が上記絞り流路３６からのみリッド１の下部にはみ出し、フラッシュサーフェイス面にバリが生ずることはなく、また絞り流路３６から余分の発泡性樹脂材料４がはみ出す際の流通抵抗により、隙間ｄ内は所定の圧力に保持されるので、発泡性樹脂材料４の硬化時に上面に凹み等が発生することもなく、フラッシュサーフェイス面は良好な平坦度が確保される。
尚、図２において、リップ部３４を絞り流路３６に変えた点以外の構成は、図１のものと同じであり、図１と同一の符号は図１と同一の部分を表しており、また保持金具２の保持フランジ２１へのウエザストリップ３の組付け及び該保持金具２をリッド１に取付けるときリッド１の外周端面と基部３１との隙間ｄによってリッド１の外形寸法のばらつきを吸収すること等は、図１の第１実施例と全く同じであり、作用，効果においても図１の第１実施例のものと同じである。
【００２２】
図３，図４及び図５は、本発明の第３，第４及び第５の実施例を示すものであり、これらの例では下側面部３３の内側端部に設けられる立上り部３５の上端面がリッド１の下面に当接して密閉シールされる構造とすると共に、余剰の発泡性樹脂材料４を逃がすオリフィス３７を設けたもので、それ以外の構成は図１及び図２の実施例と同じであり、図３，図４及び図５において図１及び図２と同一の符号は図１，２と同一の部分を表している。また、図３，図４及び図５の実施例において、保持金具２の保持フランジ２１へのウエザストリップ３の組付け及び該保持金具２をリッド１に取付けるときリッド１の外周端面と基部３１との隙間ｄによってリッド１の外形寸法のばらつきを吸収すること等は、図１及び図２の各実施例と同じであり、作用，効果においても図１及び図２の各実施例のものと同じである。
【００２３】
これら図３，図４及び図５の例においても、図１及び図２の場合と同様に、ウエザストリップ３の取付け後、リッド１の外周端面とウエザストリップ３の基部３１との隙間ｄに発泡性樹脂材料４を注入し、隙間ｄの上面を上面密閉用部治具５で密閉した状態で発泡性樹脂材料４を発泡膨張させるものであり、そのとき余剰の発泡性樹脂材料４は、図３の例では下側面部３３に設けたオリフィス３７から保持金具２に設けた穴２２を通って保持金具２の下側にはみ出し、図３（Ｂ）に示すように、硬化後にはみ出した発泡性樹脂材料４を取り除いて製品とする。
図４の例では、余剰の発泡性樹脂材料４は下側面部３３に設けたオリフィス３７から保持金具２に形成した溜り部２３内にはみ出す。図５の例では、基部３１に溜り部３８を形成し、余剰の発泡性樹脂材料４は基部３１の内側面部に設けたオリフィス３７から溜り部３８へとはみ出す。
【００２４】
このようにオリフィス３７が余剰の発泡性樹脂材料の逃がし弁として機能し、余剰の発泡性樹脂材料４がオリフィス３７からのみはみ出すことにより、フラッシュサーフェイス面にバリが生ずることはない。またオリフィス３７から余分の発泡性樹脂材料４がはみ出す際の流通抵抗により、隙間ｄ内は所定圧力に保持されるので、発泡性樹脂材料４の硬化時に上面に凹み等が発生することもなく、フラッシュサーフェイス面は良好な平坦度が確保される、という図１，図２の場合と同様の作用，効果を奏するものである。
【００２５】
図６及び図７は、本発明の第６及び第７の実施例を示すものであり、この図６及び図７では下側面部をもたないウエザストリップ３であって基部３１の上部に係合溝３１ｂが形成され、保持部材２の外側端部には縦壁部２４が上向きに形成され、且つ該縦壁部２４の上端から下方に折返されて下向きの保持フランジ２５が形成され、上記基部３１の係合溝３１ｂに該保持フランジ２５を嵌入係合させることによりウエザストリップ３が保持金具２に組付けられ、その状態で保持金具２をリッド１の周縁部分の下部に取付けることにより、上記保持金具２の縦壁部２４の内側面がリッド１の外周端面の外側に隙間ｄをもって対向し、該縦壁部２４の上端部及び基部３１の上面がリッド１の上面と同一面上に位置した状態でウエザストリップ３がリッド１に取付けられる構造となっており、リッド１の外周端面と上記縦壁部２４との隙間ｄによって、リッド１の外形寸法のばらつきを吸収し、リッド１の閉状態において、ウエザストリップ３の弾接部３２がルーフ開口部の周縁フランジに程よく弾接してリッド１の密閉シール性が確保されるようになっている。
【００２６】
上記の構成に加え、図６の実施例では、保持金具２のリッド１の下面に対向する位置に、先端がリッド１の下面に弾接するリップ部７１をもったゴム等の弾性材よりなる逃がし弁部材７を固着した構成となっており、図７では、保持金具２に形成した突出部２６がリッド１の下面に近接対向して絞り通路２７を形成した構成となっている。
【００２７】
上記構成において、隙間ｄに発泡性樹脂材料４を注入し、該隙間ｄの上面を上面密閉用治具５にて密閉して発泡性樹脂材料４を発泡膨張させる。
発泡性樹脂材料４の発泡膨張が進み、隙間ｄの内部圧力が上昇すると、図６の実施例では図１の実施例の場合と同様に、その圧力上昇によりリップ部７１が押し開かれ、そこから余剰の発泡性樹脂材料４がリッド１の下部に押し出される。
図７の実施例では図２の実施例の場合と同様に、余剰の発泡性樹脂材料４が絞り通路２７より所定の流通抵抗をもって押し出される。そして、発泡性樹脂材料４の硬化をまって上面密閉用治具５を取り外すことにより、隙間ｄが発泡性樹脂材料４にて充填された完成品を得ることができる。
【００２８】
このように逃がし弁部材７のリップ部７１及び絞り通路２７が何れも図１のリップ部３４及び図２の絞り通路３６と同様に余剰の発泡性樹脂材料４を逃がす逃がし弁として機能することにより、図１及び図２の実施例と全く同じ作用，効果を奏するものである。
【００２９】
上記各実施例ではガラスよりなるリッドの外周端面部にウエザストリップを取付ける場合について示しているが、本発明はガラス以外のリッドの外周端面部にウエザストリップを取付ける場合にも適用可能である。
【００３０】
【発明の効果】
以上のように本発明によれば、ウエザストリップがリッドの外周端面の外側に隙間ｄをもって取付けられる構成を採ることにより、該隙間にてリッドの外形寸法のばらつきはほぼ完全に吸収され、リッドの閉状態においてウエザストリップがルーフ開口部の周縁フランジに程よく弾接して確実な密閉シール性が確保されると共に、フラッシュサーフェイス性が損なわれることもなく、また汎用的な簡単な設備にて安価な製造が可能となる。
【００３１】
また、上記隙間ｄに発泡性樹脂材料を注入し、隙間の上面を密閉した状態で発泡膨張させると共に、余剰の発泡性樹脂材料が上面密閉部以外の位置に設けた逃がし弁部より逃がす構成を採っていることにより、上面密閉部に発泡性樹脂材料のはみ出しによるバリが発生するようなことはなく、硬化後の発泡性樹脂材料の上面に凹み等が発生することもなく、フラッシュサーフェイス面には良好な平坦度が確保される。

BACKGROUND OF THE INVENTION
The present invention relates to a method of attaching a weather strip to the periphery of the lid provided in an opening of the vehicle roof.
[0002]
[Prior art]
An opening is provided in a part of the roof of the vehicle, and a lid made of glass is slidably attached to the opening, and by operating the drive motor, the glass lid is slid rearward to open the roof opening. A device that slides the glass lid forward to seal the opening of the roof is generally called a sunroof device and is installed in more vehicles than before.
[0003]
In the sunroof apparatus as described above, a weather strip made of an elastic material such as rubber is attached to the outer peripheral edge of the lid made of glass, and attached to the outer peripheral edge of the lid in a closed state of the lid. The weather strip is elastically brought into contact with the peripheral flange of the roof opening to hermetically seal the opening.
[0004]
As a method of attaching the weather strip to the outer peripheral edge of the glass lid, for example, as disclosed in Japanese Utility Model Laid-Open No. 5-80845, the holder is integrated with a retainer fixed to the lower surface of the peripheral edge of the glass. And a method of fitting the weather strip to the holder and attaching the weather strip to the outer peripheral edge of the glass lid as disclosed in Japanese Patent Laid-Open No. 6-191280. A method of forming a synthetic resin frame having a peripheral groove and attaching a weather strip to the peripheral groove of the synthetic resin frame has been developed.
[0005]
[Problems to be solved by the invention]
Of the conventional weather strip mounting methods described above, the method of mounting the weather strip by engaging it with the holder absorbs variations in the outer dimensions of the lid by elastic deformation of the weather strip itself. If the variation in the outer shape exceeds the allowance for elastic deformation, a gap will be created between the weather strip and the peripheral flange of the roof opening when the lid is closed, or the sealing performance will be impaired, or the weather strip Is pressed too hard against the peripheral flange and bulges upward into a convex shape, which may impair flash surface formation.
[0006]
Further, the method of forming the synthetic resin frame on the outer peripheral edge of the glass lid is very expensive for both the synthetic resin injection molding equipment and the mold, and requires a dedicated mold for each vehicle type. Therefore, there is a problem that it is very difficult to employ practically.
[0007]
An object of the present invention is to solve the conventional problems as described above, and to provide a weather strip mounting method capable of satisfying hermetic sealing properties and flash surface properties and reducing the number of mounting steps and costs. Is.
[0008]
[Means for Solving the Problems]
According to the present invention, a weather strip that is attached to the outer peripheral portion of the lid and performs a sealing function when the lid is closed is attached to the lid with a holding bracket so as to face the outer peripheral end surface of the lid with a predetermined gap d. The variation in dimensions can be absorbed in the gap d. Further, only the upper surface of the gap d is opened, and the other portions communicate with the outside only through the relief valve function part, and a foamable resin material is injected into the gap d, and the upper surface of the gap d The foamable resin material is expanded and expanded in a state of being sealed with an upper surface sealing jig. After the expansion of the foaming progresses and the gap d is filled with the foamable resin material, the excess foamable resin material is removed from the relief valve. By extruding from the functional portion, and then curing the foamable resin material in the gap d and removing the upper surface sealing jig, the gap d is filled with the foamable resin material, and the outer periphery of the weather from the lid It is possible to obtain a finished product in which a flash surface surface with good flatness is formed on the strip.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
FIG. 1 shows a first embodiment of the present invention, wherein 1 is a lid made of glass, 2 is a holding metal fitting attached to the lower part of the peripheral portion of the lid 1, and the outer end of the holding metal fitting 2 is shown. A holding flange 21 is bent upward at the portion, and the weather strip 3 is engaged and held by the holding flange 21.
[0011]
The weather strip 3 includes a base portion 31 having an engagement groove 31a into which the holding flange 21 of the holding metal fitting 2 is fitted and engaged, an elastic contact portion 32 protruding in an arc shape outside the base portion 31, and the base portion 31. It is integrally formed of an elastic material such as rubber in a shape having a lower side surface portion 33 that goes around to the lower side of the lid 1 from the inner lower portion. A lip portion 34 that elastically contacts the lower surface of the lid 1 is formed on the lower side surface portion 33 so as to protrude upward.
[0012]
As shown in FIG. 1A, the weather strip 3 is assembled to the holding metal fitting 2 by fitting and engaging the holding flange 21 in the engaging groove 31a of the base portion 31, and the holding metal fitting 2 is lidded in this state. 1, the inner surface of the base 31 of the weather strip 3 faces the outside of the outer peripheral end surface of the lid 1 with a gap d, and the upper surface of the base 31 is located on the same plane as the upper surface of the lid 1. The mounting state is such that the lip portion 34 of the lower side surface portion 33 is in elastic contact with the lower surface of the lid 1.
[0013]
At this time, the variation in the external dimensions of the lid 1 made of glass is absorbed by the gap d between the outer peripheral end surface of the lid 1 and the inner side surface of the base 31, so that the elastic contact portion 32 is attached in the attached state of the weather strip 3. The variation in the tip position is eliminated.
[0014]
Next, as shown in FIG. 1B, an appropriate amount of a foamable resin material (including a heat-foamable resin material) 4 is injected into the gap d between the outer peripheral end surface of the lid 1 and the base portion 31 with an injection nozzle 6. As shown in FIG. 1 (C), the upper surface (flash surface surface) of the gap d is sealed with an upper surface sealing jig 5 made of a resin material or a metal material, and a foamable resin material is injected. 4 is expanded.
[0015]
As shown in FIG. 1E, when the expansion of the foamable resin material 4 fills the gap d as shown in FIG. 1D and further expands and the internal pressure of the gap d rises as shown in FIG. As the pressure rises, the lip portion 34 is pushed inward, and the surplus foamable resin material 4 is pushed out from the lower portion of the lid 1.
[0016]
Thereafter, the foamable resin material 4 is cured and the upper surface sealing jig 5 is removed to obtain a finished product in which the gap d is filled with the foamable resin material 4 as shown in FIG. be able to.
[0017]
In the above, the elastic contact portion of the lip portion 34 to the lower surface of the lid is a so-called relief valve (pressure valve) that is pushed open when the internal pressure of the gap d exceeds a predetermined value to release the excess foamable resin material 4. By setting the sealing force of the lip portion 34 to a value lower than the sealing force of the upper surface sealing jig 5, the surplus foamable resin material 4 can be elastically contacted with the lip portion 34. Since the burr is not generated by the expansion of the foamable resin material in the sealed portion by the upper surface sealing jig 4 and the pressure in the gap d is maintained at almost the set value. When the material 4 is cured, there is no dent or the like on the upper surface, and the flatness of the flash surface is ensured.
[0018]
Furthermore, if the above-described weather strip mounting method is employed, the variation in the outer dimensions of the lid 1 is almost completely absorbed, and the elastic contact portion 32 of the weather strip 3 is located at the roof opening when the lid 1 is closed. The lid 1 is elastically contacted with the peripheral flange to ensure the hermetic sealing performance of the lid 1, and the flash surface performance is not impaired, and low-cost production is possible with a general-purpose simple facility.
[0019]
FIG. 2 shows a second embodiment of the present invention. Instead of the lip portion 34 of the first embodiment shown in FIG. 1, a throttle channel between the lower side surface portion 33 and the lower surface of the lid 1 is shown. 36 is provided, and the throttle channel 35 is provided with a function as a relief valve for excess foamable resin material 4.
[0020]
That is, in FIG. 2, a rising portion 35 is provided at the inner end portion of the lower side surface portion 33, and when the weather strip 3 is attached, the upper end portion of the rising portion 35 comes close to and faces the lower surface of the lid 1. In this structure, the path 36 is formed.
[0021]
Also in this example, the foamable resin material 4 is injected into the gap d between the outer peripheral end surface of the lid 1 and the base 31 of the weather strip 3 after the weather strip 3 is attached, as in the case of FIG. The foamable resin material 4 is expanded and expanded in a state where the upper surface of the resin is sealed with the upper surface sealing part jig 5, and at that time, the surplus foamable resin material 4 is brought into the lower part of the lid 1 only from the throttle channel 36. No burrs are generated on the surface of the flash or the flash surface, and the gap d is maintained at a predetermined pressure due to the flow resistance when the excess foamable resin material 4 protrudes from the throttle channel 36. When the material 4 is cured, there is no dent or the like on the upper surface, and the flatness of the flash surface is ensured.
2 is the same as that of FIG. 1 except that the lip portion 34 is changed to the throttle channel 36, and the same reference numerals as those in FIG. 1 represent the same parts as in FIG. Further, when the weather strip 3 is assembled to the holding flange 21 of the holding metal fitting 2 and the holding metal fitting 2 is attached to the lid 1, the gap d between the outer peripheral end surface of the lid 1 and the base portion 31 absorbs variations in the outer dimensions of the lid 1. This is exactly the same as the first embodiment of FIG. 1, and the operation and effect are the same as those of the first embodiment of FIG.
[0022]
3, 4 and 5 show the third, fourth and fifth embodiments of the present invention. In these examples, the upper portion of the rising portion 35 provided at the inner end portion of the lower side surface portion 33 is shown. The end surface is in contact with the lower surface of the lid 1 and is hermetically sealed, and an orifice 37 is provided to allow excess foamable resin material 4 to escape. Other configurations are the same as in the embodiment of FIGS. 3, 4 and 5, the same reference numerals as those in FIGS. 1 and 2 represent the same parts as those in FIGS. 1 and 2. 3, 4, and 5, when the weather strip 3 is assembled to the holding flange 21 of the holding metal fitting 2 and the holding metal fitting 2 is attached to the lid 1, the outer peripheral end face and the base portion 31 of the lid 1. The variation in the external dimensions of the lid 1 by absorbing the gap d is the same as that of the embodiments of FIGS. 1 and 2, and the operation and effect are the same as those of the embodiments of FIGS. The same.
[0023]
3, 4, and 5, the gap d between the outer peripheral end surface of the lid 1 and the base 31 of the weather strip 3 after the weather strip 3 is attached, as in the case of FIGS. 1 and 2. The foamable resin material 4 is injected and the foamable resin material 4 is expanded and expanded in a state where the upper surface of the gap d is sealed with the upper surface sealing part jig 5. In the example of FIG. 3, it protrudes from the orifice 37 provided in the lower side surface portion 33 through the hole 22 provided in the holding metal fitting 2 to the lower side of the holding metal fitting 2 and protrudes after curing as shown in FIG. 3 (B). The foamable resin material 4 is removed to obtain a product.
In the example of FIG. 4, the surplus foamable resin material 4 protrudes from the orifice 37 provided in the lower side surface portion 33 into the pool portion 23 formed in the holding metal fitting 2. In the example of FIG. 5, a reservoir portion 38 is formed in the base portion 31, and excess foamable resin material 4 protrudes from the orifice 37 provided on the inner side surface portion of the base portion 31 to the reservoir portion 38.
[0024]
Thus, the orifice 37 functions as a relief valve for the surplus foamable resin material, and the surplus foamable resin material 4 protrudes only from the orifice 37, so that no flash is generated on the flash surface. Further, because the flow resistance when the excess foamable resin material 4 protrudes from the orifice 37, the gap d is maintained at a predetermined pressure, so that no depression or the like occurs on the upper surface when the foamable resin material 4 is cured. The flash surface has the same function and effect as in FIGS. 1 and 2 that good flatness is ensured.

[0029]
In each of the above embodiments, the case where the weather strip is attached to the outer peripheral end surface portion of the lid made of glass is shown. However, the present invention is also applicable to the case where the weather strip is attached to the outer peripheral end surface portion of the lid other than glass. .
[0030]
【The invention's effect】
As described above, according to the present invention, by adopting a configuration in which the weather strip is attached to the outside of the outer peripheral end surface of the lid with the gap d, the variation in the external dimension of the lid is almost completely absorbed by the gap, and the lid In the closed state, the weatherstrip is elastically contacted with the peripheral edge flange of the roof opening to ensure a reliable hermetic seal, without impairing the flash surface properties, and inexpensive with general-purpose simple equipment Manufacturing becomes possible.
[0031]
In addition, the foaming resin material is injected into the gap d, and the foaming expansion is performed in a state where the upper surface of the gap is sealed, and the excess foaming resin material is released from a relief valve portion provided at a position other than the top sealing portion. By adopting it, there is no occurrence of burrs due to the protrusion of the foamable resin material in the upper surface sealing part, and there is no dent or the like on the upper surface of the foamed resin material after curing. Good flatness is ensured.
