Description
本発明は、自動車ボディのドア開口周縁部に沿って設けられたフランジに取付けられるオープニングトリムに関するものである。 The present invention relates to an opening trim that is attached to a flange provided along a peripheral edge of a door opening of an automobile body.
自動車ボディのドア開口周縁部に沿って設けられた板状のフランジ１０１には、例えば、図９に示すようなオープニングトリム１０が取付けられている。
オープニングトリム１０は、フランジＦが開口側から挿入されるようにして嵌め込まれる、車外側側壁１１ａ，車内側側壁１１ｂ及び両側壁１１ａ，１１ｂを連結する底壁１１ｃからなる断面略Ｕ字形状の取付基部１１と、取付基部１０の車外側側壁１１ａの内方（車内側）に設けられ、取付基部１１の開口側から挿入されたフランジ１０１の車外側側面に摺接する複数の突条部１２と、車内側側壁１２の内方（車外側）に設けられ、同じく取付基部１１の開口側から挿入されたフランジ１０１の車内側側面に摺接する断面略舌状の保持リップ部１３を備え、取付基部１１には断面略Ｕ字形状の芯材１４が埋設されている。また、車内側側壁１１ａと底壁１１ｃとの連結位置には車内側に延びる断面略舌状の装飾リップ部１５が設けられている（例えば、特許文献１参照）。
For example, an opening trim 10 as shown in FIG. 9 is attached to a plate-like flange 101 provided along the peripheral edge of the door opening of the automobile body.
The opening trim 10 is fitted in such a manner that the flange F is inserted from the opening side, and has a substantially U-shaped cross section including a vehicle outer side wall 11a, a vehicle inner side wall 11b, and bottom walls 11c that connect both side walls 11a and 11b. A plurality of ridges 12 that are provided on the inner side (vehicle inner side) of the vehicle outer side wall 11a of the mounting base 10 and are in sliding contact with the vehicle outer side surface of the flange 101 inserted from the opening side of the mounting base 11; A holding lip portion 13 having a substantially tongue-shaped cross section is provided on the inner side (outside of the vehicle) of the vehicle inner side wall 12 and slidably contacts the vehicle inner side surface of the flange 101 inserted from the opening side of the mounting base 11. A core material 14 having a substantially U-shaped cross section is embedded in the core. Further, a decorative lip portion 15 having a substantially tongue-shaped cross section extending inward of the vehicle is provided at a connection position between the vehicle inner side wall 11a and the bottom wall 11c (see, for example, Patent Document 1).
そして、オープニングトリム１０は、ドアの閉時にドア側に設けられた中空シール部（図示しない）に車外側側壁１１ａが弾接して車内外をシールするようになっている。
また、車外側側壁１１ａに中空シール部を設けて、ドアの閉時にドアに対してオープニングトリム側に設けた中空シール部を弾接して車内側をシールするものも知られている（例えば、特許文献２参照）。
When the door is closed, the opening trim 10 is configured so that the vehicle outer side wall 11a is in elastic contact with a hollow seal portion (not shown) provided on the door side to seal the inside and outside of the vehicle.
Further, there is also known a method in which a hollow seal portion is provided on the vehicle outer side wall 11a, and the vehicle inside is sealed by elastically contacting the hollow seal portion provided on the opening trim side with respect to the door when the door is closed (for example, patents). Reference 2).
このようなオープニングトリム１０において軽量化を図るため、取付基部１１，突条部１２及び保持リップ部１３をスポンジ材で形成し、芯材１４についても樹脂製又は薄肉の金属製のものを使用することが行われている。
しかしながら、この場合、保持力が低下するのでフランジ１０１からオープニングトリム１０が抜け易くなるといった問題がある。
In order to reduce the weight of the opening trim 10, the mounting base portion 11, the ridge portion 12 and the holding lip portion 13 are formed of a sponge material, and the core material 14 is also made of resin or thin metal. Things have been done.
However, in this case, since the holding force is reduced, there is a problem that the opening trim 10 is easily detached from the flange 101.
これに対して、保持リップ部１３の肉厚を厚くしたりあるいは材質を変えることによって剛性を高める方法があるが、保持リップ部１３の剛性が強すぎると、特に芯材１４を樹脂製又は薄肉の金属製のものにした場合にはその芯材１４で取付基部１１の形状を支えることができなくなり、図１０に示すように、フランジ１０１に対してオープニングトリム１０を引き抜く方向（図１０では下側）に力が作用すると、取付基部１１の開口が広くなるといった、いわゆる「口開き」の現象が発生してますます保持力が低下するといった不具合があった。 On the other hand, there is a method of increasing the rigidity by increasing the thickness of the holding lip 13 or changing the material. However, if the rigidity of the holding lip 13 is too strong, the core material 14 is made of resin or thin. When the metal base is made of metal, the shape of the mounting base 11 cannot be supported by the core member 14, and the opening trim 10 is pulled out from the flange 101 as shown in FIG. When a force is applied to the side), a so-called “open mouth” phenomenon occurs in which the opening of the mounting base 11 is widened, and the holding force is further reduced.
また、特許文献１に記載の発明は、主リップに近接した位置に補助リップを突設して保持力を増大させるものであるが、フランジの板厚が変化する場合には対応することができないといった問題があった。また、車内側に断面形状の大きいフランジ保持用のリップを一枚多く設ける必要があるので、構造が複雑になるとともに材料費も高くなるという不具合もあった。
さらに、特許文献２に記載の発明は、車内側保持リップの車外側面から断面略半円形の突起部を設けるとともに突起部に連続して凹状に湾曲形成した部位を設けることによってフランジの板厚の変化にも対応させたものであるが、フランジの板厚が大きく変化する場合、例えば、フランジが一枚から三枚重ねのものになる場合、あるいは、その逆に三枚から一枚になる場合にはフランジの板厚の変化に対応することが困難である。つまり、フランジが一枚から二枚，二枚から三枚あるいはその逆のようにフランジ一枚分の厚さの変化程度には対応できても、フランジ二枚分の厚さの変化といった大きな厚さの変化に対応することは困難でフランジが三枚から一枚になった場合にはフランジに対する保持力が不十分となる。
Further, the invention described in Patent Document 1 is designed to increase the holding force by projecting an auxiliary lip at a position close to the main lip, but it cannot cope with the case where the flange thickness changes. There was a problem. In addition, since it is necessary to provide one more lip for holding a flange having a large cross-sectional shape on the inner side of the vehicle, there is a problem that the structure is complicated and the material cost is increased.
Furthermore, in the invention described in Patent Document 2, the thickness of the flange plate can be increased by providing a substantially semicircular cross-sectional protrusion from the vehicle outer surface of the vehicle inner side holding lip and a concavely curved portion continuously from the protrusion. Although it corresponds to the change, when the plate thickness of the flange changes greatly, for example, when the flange is from one to three, or vice versa, from three to one It is difficult to cope with changes in the plate thickness of the flange. In other words, even if it can cope with the change in thickness of one flange, such as one to two flanges, two to three flanges, or vice versa, a large thickness such as a change in the thickness of two flanges. It is difficult to cope with the change of the height, and when the flange is changed from three to one, the holding force to the flange becomes insufficient.
そこで本発明の目的は、フランジの板厚が大きく変化する場合でも十分な保持力を発揮することのできるオープニングトリムを提供することにある。 Therefore, an object of the present invention is to provide an opening trim that can exhibit a sufficient holding force even when the plate thickness of the flange changes greatly.

本発明のオープニングトリムによれば、取付基部の車内側側壁の内方から底壁側に傾斜して車外側側壁に向かって延びるように設けられ、フランジの車内側側面に摺接する断面略舌状の保持リップ部を発泡材料で形成するとともに、保持リップ部の断面形状における長さを、取付基部の車外側側壁と車内側側壁の開口間の距離よりも長くし、車内側側壁寄りと車外側側壁寄りに、保持リップ部を底壁側に二段階に折り曲げる第一折れ点と第二折れ点を設けたので、オープニングトリムを、板厚が厚肉Ｔのフランジに取付けるとき、保持リップ部は、第一折れ点より先の部分が取付基部の底壁側に向けて折れ曲がり、フランジの車内側側面に、保持リップ部の第一折れ点と第二折れ点の間の部位が摺接するとともに、フランジの車外側側面に、取付基部に設けられた突条部が摺接し、保持リップ部の第一折れ点と第二折れ点の間の部位と突条部との間でフランジは挟持された状態となり、フランジにオープニングトリムが取付けられる。 According to the opening trim of the present invention, the mounting base portion is provided so as to incline from the inner side of the vehicle interior side wall toward the bottom wall side and extend toward the vehicle outer side wall, and has a substantially tongue-shaped cross section that is in sliding contact with the vehicle interior side surface of the flange. The holding lip portion is formed of a foam material, and the length of the holding lip in the cross-sectional shape is longer than the distance between the opening of the vehicle outer side wall and the vehicle inner side wall of the mounting base, Since the first fold point and the second fold point at which the holding lip portion is bent in two steps are provided near the side wall, when the opening trim is attached to the flange having a thick plate thickness T, the holding lip portion is The portion ahead of the first folding point bends toward the bottom wall side of the mounting base, and the portion between the first folding point and the second folding point of the holding lip portion is in sliding contact with the inner side surface of the flange, On the outer side of the flange, The ridge provided on the base is in sliding contact, and the flange is sandwiched between the ridge and the portion between the first fold point and the second fold point of the holding lip, and the opening trim is attached to the flange.

このとき、保持リップ部から、第一折れ点を中心に折れ曲がった第一折れ点より先の部分が元に戻ろうとする反力が、第一折れ点と第二折れ点の間の部位からフランジに伝わり、フランジを突条部側に押圧するので、オープンニングトリムは安定した状態でフランジに取付けられる。また、オープンニングトリムの取付時には、保持リップ部は第一折れ点を中心に積極的に折れ曲がるので、板厚の厚いフランジであっても、取付基部の開口側から容易に挿入することができ、オープニングトリムを容易に嵌め込むことができる。 At this time, from the holding lip part, the reaction force that the part ahead of the first fold point bent around the first fold point tries to return to the original, the flange from the part between the first fold point and the second fold point Therefore, the opening trim is attached to the flange in a stable state. In addition, when installing the opening trim, the holding lip part actively bends around the first folding point, so even a thick flange can be easily inserted from the opening side of the mounting base, Opening trim can be easily fitted.
またオープニングトリムを、板厚が薄肉Ｓのフランジに取付けるとき、保持リップ部は、第一折れ点より先の部分が取付基部の底壁側に向けて折れ曲がるとともに、第二折れ点を中心に第二折れ点より先の部分もさらに取付基部の底壁側に向けて折れ曲がり、フランジの車内側側面に、保持リップ部の先端と第二折れ点との間の部位が摺接するとともに、フランジの車外側側面に、取付基部に設けられた突条部が摺接し、保持リップ部の先端と第二折れ点との間の部位との間でフランジは挟持された状態となり、フランジにオープニングトリムが取付けられる。 Further, when the opening trim is attached to the flange having a thin plate thickness S, the holding lip portion is bent toward the bottom wall side of the mounting base portion at the first fold point, and the second fold point is the center. The part beyond the second folding point also bends toward the bottom wall of the mounting base, and the part between the tip of the holding lip and the second folding point is in sliding contact with the inner side surface of the flange, and the flange wheel The protrusion on the mounting base is in sliding contact with the outer side surface, and the flange is sandwiched between the tip of the holding lip and the second folding point, and the opening trim is attached to the flange. It is done.
このとき、保持リップ部から、第一折れ点を中心に折れ曲がった第一折れ点より先の部分が元に戻ろうとする反力に加えて、第二折れ点を中心に折れ曲がった第二折れ点より先の部分も元に戻ろうとする反力も、保持リップ部の先端と第二折れ点の間の部位から集中してフランジに伝わり、フランジを突条部側に押圧するので、オープンニングトリムは安定した状態でフランジに取付けられる。特に、保持リップ部の先端の取付基部の底壁側は切り欠かれるか、又は保持リップ部の先端の剛性を保持リップ部の他の部位の剛性よりも低くしていることにより、保持リップ部の先端の撓み量は大きく、しかも保持リップ部は発泡スポンジ材からなるので、保持リップ部の先端と第二折れ点の間の部位は、フランジの車内側側面に大きく密着した状態でくいつく。
よって、オープニングトリムが薄肉Ｓのフランジに取付けられた状態からオープニングトリムを引き抜く方向に力が作用しても、保持リップ部の先端と第二折れ点の間の部位に集中した反力がフランジにかかり突条部との間でフランジは強く挟持されるので、たとえ芯材として金属性であっても薄肉のもの又は樹脂性のものを使用したとしてもフランジからオープニングトリムが容易に離れることはない。
また、オープニングトリムの取付時には、保持リップ部は第一折れ点より先側が折れ曲がることに加え、第二折れ点より先端も折れ曲がるので、板厚の薄いフランジを取付基部の開口側から容易に挿入することができ、オープニングトリムを容易に嵌め込むことができる。
At this time, in addition to the reaction force that the part ahead of the first folding point bent from the holding lip portion tries to return to the original, the second folding point bent around the second folding point The reaction force that tries to restore the earlier part also concentrates from the part between the tip of the holding lip part and the second folding point and is transmitted to the flange, pressing the flange toward the ridge part, so the opening trim is Mounted on the flange in a stable state. In particular, the bottom wall side of the mounting base portion at the tip of the holding lip portion is notched, or the holding lip portion has a lower rigidity than the other portions of the holding lip portion. Since the bending amount of the tip of the lip portion is large and the holding lip portion is made of a foamed sponge material, the portion between the tip of the holding lip portion and the second folding point sticks to the side of the flange inside the vehicle.
Therefore, even if a force acts in the direction in which the opening trim is pulled out from the state where the opening trim is attached to the thin-walled flange S, the reaction force concentrated on the portion between the tip of the holding lip portion and the second folding point is applied to the flange. Since the flange is strongly sandwiched between the ridges, the opening trim is not easily separated from the flange even if the core material is metallic, thin or resinous. .
In addition, when installing the opening trim, the holding lip part bends from the first folding point and the tip also bends from the second folding point, so a thin flange can be easily inserted from the opening side of the mounting base. And the opening trim can be easily fitted.
このように、本発明のオープニントリムによれば、板厚が厚肉Ｔのフランジから、薄肉Ｓのフランジまでオープニントリムを十分な保持力で取付けることができ、しかもフランジを取付基部の開口側から容易に挿入することができる。 As described above, according to the open trim of the present invention, the open trim can be attached with a sufficient holding force from the flange having the thick wall thickness T to the flange having the thin wall S, and the flange can be attached from the opening side of the mounting base. Can be inserted easily.
また、本発明によれば、保持リップ部の第二折れ点を取付基部の開口側に、例えばその側面に角部として設けるとともに、薄肉Ｓのフランジの車外側側面が突条部に摺接したときの、薄肉Ｓのフランジの車内側側面よりも車外側の位置にしたので、薄肉Ｓのフランジであっても保持リップ部の先端と突条部との間でフランジは強く挟持される。 Further, according to the present invention, the second folding point of the holding lip portion is provided on the opening side of the mounting base, for example, as a corner portion on the side surface thereof, and the vehicle outer side surface of the thin S flange is in sliding contact with the ridge portion. At that time, the flange is strongly clamped between the tip of the holding lip portion and the protruding portion even when the flange is thin S, because the position is on the vehicle outer side than the vehicle inner side surface of the flange of the thin wall S.
さらに、本発明によれば、保持リップ部の第二折れ点を取付基部の開口側、例えばその側面に角部として設けるとともに、薄肉のフランジの車内側側面に摺接する保持リップ部の第二折れ点から先端までを平坦にしたので、フランジに対する密着度は高くなり一層保持力は向上する。 Furthermore, according to the present invention, the second folding point of the holding lip portion is provided as a corner portion on the opening side of the mounting base, for example, the side surface thereof, and the second fold portion of the holding lip portion that is in sliding contact with the vehicle inner side surface of the thin flange is provided. Since the point to the tip is flattened, the degree of adhesion to the flange is increased and the holding force is further improved.
また、本発明によれば、保持リップ部の断面形状において、取付基部の底壁側の側面を開口側に向けて膨出湾曲させて、板厚が厚肉Ｔのフランジに取付けられるときに保持リップ部と取付基部の車内側側壁との間に隙間を生じさせるようにしたので、保持リップ部からの力が車内側側壁に直接大きく伝わることはなく、これにより、板厚が厚肉Ｔのフランジに取付けられたオープニングトリムの取付基部の開口が広くなるといった、「口開き」の発生を防止することができる。 Further, according to the present invention, in the cross-sectional shape of the holding lip portion, the side surface on the bottom wall side of the mounting base portion is bulged and curved toward the opening side, and is held when the plate is attached to the flange having the thick wall T. Since a gap is generated between the lip portion and the vehicle interior side wall of the mounting base, the force from the holding lip portion is not directly transmitted directly to the vehicle interior side wall. It is possible to prevent the occurrence of “opening” such that the opening of the mounting base portion of the opening trim attached to the flange becomes wide.
また、本発明によれば、取付基部及び突条部を、保持リップ部とともに発泡材料で形成したので、オープニングトリム全体の軽量化が図れる。 Moreover, according to this invention, since the attachment base part and the protrusion part were formed with the foam material with the holding lip part, the weight reduction of the whole opening trim can be achieved.
また、本発明によれば、突条部に、取付基部の開口側から底壁側にかけて厚みをテーパー状に厚くした傾斜部を形成したので、保持リップ部の先端が対向する突条部に弾接することがあっても、保持リップ部の先端は傾斜部に沿って円滑に車内側側壁側に撓む。
これにより、フランジにオープニングトリムを取付けるときに、保持リップ部の先端が突条部側に引っ掛かり挿入荷重を急激に増大させるといった事態の発生を防止することができる。
Further, according to the present invention, since the inclined portion is formed with a taper-like thickness from the opening side to the bottom wall side of the mounting base portion, the protrusion of the holding lip portion is elastically formed on the protruding ridge portion. Even if it contacts, the front-end | tip of a holding | maintenance lip part bends to a vehicle inner side wall side smoothly along an inclination part.
Thereby, when attaching the opening trim to the flange, it is possible to prevent the occurrence of a situation in which the tip of the holding lip portion is caught on the protruding portion side and the insertion load is rapidly increased.
図１乃至図５を参照して、本発明の実施形態に係るオープニングトリム３０について説明する。図１は本発明の実施形態に係るオープニングトリム３０を示す断面図であり、図２乃至図５は、オープニングトリム３０が取付けられるフランジ１０２，１０３との関係を示す断面図である。 With reference to FIG. 1 thru | or FIG. 5, the opening trim 30 which concerns on embodiment of this invention is demonstrated. FIG. 1 is a cross-sectional view showing an opening trim 30 according to an embodiment of the present invention, and FIGS. 2 to 5 are cross-sectional views showing the relationship with flanges 102 and 103 to which the opening trim 30 is attached.
本発明の実施形態に係るオープニングトリム３０は、取付基部３１，突条部３２，保持リップ部３３及び取付基部３１に埋設された芯材３４を備えていて、板厚が厚肉Ｔのフランジ１０２から薄肉Ｓのフランジ１０３までのものに取付可能になっている。ここでは、厚肉Ｔのフランジ１０２を三枚重ねのもの、薄肉Ｓのフランジ１０３を一枚のものにしているので、その中間となるフランジが二枚重ねのものにも取付可能である。板厚最大の厚肉Ｔのフランジ１０２の肉厚としては、５〜１０ミリメートル（ｍｍ）のものを使用し、板厚最小の薄肉Ｓのフランジ１０３の肉厚としては、０．５〜５ミリメートル（ｍｍ）のものを使用した。 An opening trim 30 according to an embodiment of the present invention includes a mounting base 31, a ridge 32, a holding lip 33, and a core member 34 embedded in the mounting base 31, and a flange 102 having a thick T plate. To the flange 103 of the thin wall S can be attached. Here, since the thick-walled T flange 102 is made up of three sheets and the thin-walled S flange 103 is made up of one sheet, it is possible to attach the intermediate flange to a double-layered structure. The thickness of the flange 102 having the maximum thickness T is 5 to 10 millimeters (mm), and the thickness of the flange 103 having the minimum thickness S is 0.5 to 5 millimeters. (Mm) was used.
オープニングトリム３０の取付基部３１は、車外側側壁３１ａと車内側側壁３１ｂとそれら両側壁３１ａ，３１ｂを連結する底壁３１ｃからなる断面略Ｕ字形状をしていて、自動車ボディのドア開口周縁部に沿って設けられたフランジ１０２，１０３が取付基部３１の開口側から挿入されるようにして嵌め込まれる。ここでは、車外側側壁３１ａと車内側側壁３１ｂの断面形状における長さを略同一のものを示したが、長さの異なるものであってもよい。 The mounting base 31 of the opening trim 30 has a substantially U-shaped cross section including a vehicle outer side wall 31a, a vehicle inner side wall 31b, and a bottom wall 31c connecting both side walls 31a and 31b. Are fitted so that the flanges 102 and 103 provided along the opening are inserted from the opening side of the mounting base 31. Here, although the length in the cross-sectional shape of the vehicle outer side wall 31a and the vehicle inner side wall 31b is substantially the same, the length may be different.
突条部３２は、取付基部３１の車外側側壁３１ａの内方（車内側）に一定の間隔をおいて２つ（特にその数は限定されるものではない）設けられ、オープニングトリム３０をフランジ１０２，１０３に取付けるとき、取付基部３１の開口側から挿入されたフランジ１０２，１０３の車外側側面に摺接する。
また、突条部３２には、取付基部３１の開口側から底壁３１ｃ側にかけて厚みをテーパー状に厚くした傾斜部３２ａを形成していて、これにより突条部３２の断面形状は略直角三角形状になっている。
Two protrusions 32 are provided at a certain interval (in particular, the number is not limited) on the inner side (vehicle inner side) of the vehicle outer side wall 31a of the mounting base 31, and the opening trim 30 is flanged. When attaching to 102, 103, it comes into sliding contact with the vehicle outer side surface of the flanges 102, 103 inserted from the opening side of the attachment base 31.
In addition, the ridge portion 32 is formed with an inclined portion 32a having a tapered thickness from the opening side to the bottom wall 31c side of the mounting base portion 31, whereby the cross-sectional shape of the ridge portion 32 is a substantially right triangle. It has a shape.
保持リップ部３３は、断面略舌状で車内側側壁３１ｂ端部付近の内方から底壁３１ｃ側に傾斜して車外側側壁３１ａに向かって延びるように設けられている。ここでは、保持リップ部３３は、車内側側壁３１ｂの延びる方向に対して、約６０度の角度で延びているが、角度を小さくすると、板厚が薄肉Ｓのフランジ１０３に対する保持力が低下するとともに板厚が厚肉Ｔのフランジ１０２に対しては保持リップ部３３が車内側側壁３１ｂに当接してオープニングトリム３０の取付基部３１の開口が広くなるといった、「口開き」の発生するおそれがあるので、４５度〜７０度の範囲で望ましくは５５度〜６５度の範囲のものが好ましい。
また、保持リップ部３３の肉厚は、車外側側壁３１ａ及び車内側側壁部３１ｂの肉厚よりも厚くしている。
さらに、保持リップ部３３の断面形状における長さＬを、取付基部３１の車外側側壁３１ａと車内側側壁３１ｂの開口間の距離Ｍよりも長くし、フランジ１０２，１０３に取付けられる前の状態で、保持リップ部３３の先端の最も車外側の位置Ｐが、２つの突条部３２の間でかつ突条部３２の最も車内側の位置（フランジ１０２，１０３に取付けられた場合、突条部３２は車外側側壁３１ａの向きに押し込まれるため、フランジ１０２，１０３の車外側側面の位置よりも少し車外側の位置）よりも車外側でしかも車外側側壁３１ａに接しない位置に納まるようにしている。つまり、保持リップ部３３の先端の最も車外側の位置Ｐは、突条部３２の最も車内側の位置と車外側側壁３１ａの内方の面（車内側側面）との間になるように設定している。
そして、保持リップ部３３の底壁３１ｃ側の側面を車内側側壁３１ｂに向けて近づくように、その保持リップ部３３を折り曲げた状態（例えば、図３）において、保持リップ部３３の先端は底壁３１ｃに当接することはあっても、底壁３１ｃにより先端が折れ曲がったりして変形することはない程度の長さに設定されている。なお、図３では、保持リップ部３３の先端が底壁３１ｃに当接しないものを示している。
The holding lip portion 33 has a substantially tongue-like cross section, and is provided so as to incline from the inside in the vicinity of the end of the vehicle inner side wall 31b toward the bottom wall 31c and extend toward the vehicle outer side wall 31a. Here, the holding lip 33 extends at an angle of about 60 degrees with respect to the direction in which the vehicle interior side wall 31b extends. However, when the angle is reduced, the holding force for the flange 103 having a thin plate thickness S decreases. At the same time, for the flange 102 having a thick wall thickness T, there is a risk of “mouth opening” such that the holding lip 33 abuts against the vehicle inner side wall 31b and the opening of the mounting base 31 of the opening trim 30 becomes wide. Therefore, a range of 45 to 70 degrees is desirable, and a range of 55 to 65 degrees is desirable.
Further, the thickness of the holding lip portion 33 is larger than the thickness of the vehicle outer side wall 31a and the vehicle inner side wall portion 31b.
Further, the length L in the cross-sectional shape of the holding lip 33 is longer than the distance M between the openings of the vehicle outer side wall 31a and the vehicle inner side wall 31b of the mounting base 31, and in a state before being attached to the flanges 102 and 103. The position P of the outermost vehicle outside of the tip of the holding lip 33 is located between the two protrusions 32 and the innermost position of the protrusion 32 (when attached to the flanges 102 and 103, the protrusions 32 is pushed in the direction of the vehicle outer side wall 31a, so that it is located outside the vehicle (position slightly outside the vehicle outer side surface of the flanges 102, 103) and not in contact with the vehicle outer side wall 31a. Yes. That is, the position P on the outermost vehicle side of the tip of the holding lip 33 is set to be between the innermost position of the ridge 32 and the inner surface (vehicle inner side surface) of the vehicle outer side wall 31a. doing.
In the state where the holding lip portion 33 is bent so that the side surface of the holding lip portion 33 on the bottom wall 31c side approaches the vehicle inner side wall 31b (for example, FIG. 3), the tip of the holding lip portion 33 is the bottom. The length is set such that the tip of the bottom wall 31c does not bend and deform even if it comes into contact with the wall 31c. In FIG. 3, the holding lip 33 has a tip that does not contact the bottom wall 31 c.
そして、保持リップ部３３における取付基部３１の開口側（保持リップ部３３の表面側）にはその側面に角部として、車内側側壁３１ｂ寄りと車外側側壁３１ａ寄りに、保持リップ部３３を底壁３１ｃ側に二段階に折り曲げ易くするために第一折れ点４１と第二折れ点４２を設けている。すなわち、保持リップ部３３の断面形状で、保持リップ部３３における取付基部３１の開口側で、保持リップ部３０の付け根となる車内側側壁３１ｂの位置と第一折れ点４１を連結する線よりも、第一折れ点４１と第二折れ点４２を連結する線が取付基部３１の底壁３１ｃ側に傾くようにするとともに、その第一折れ点４１と第二折れ点４２を連結する線よりも、第二折れ点４２と保持リップ部３３の先端の最も車外側の位置Ｐを連結する線が取付基部３１の底壁３１ｃ側に傾くようにしている。
また、第一折れ点４１から第二折れ点４２までを平担にしているが、取付基部３１の開口側に膨出湾曲するように形成してもよい。また、第二折れ点４２から保持リップ部３３の先端までを平担にして、薄肉Ｓのフランジ１０３に取付けるときその平担面全域がフランジ１０３の車内側側面に密着するようにしている。
The holding lip portion 33 has a holding lip portion 33 on the opening side of the mounting base portion 31 (on the surface side of the holding lip portion 33) as a corner on its side surface, close to the vehicle inner side wall 31b and the vehicle outer side wall 31a. A first fold point 41 and a second fold point 42 are provided on the wall 31c side so as to be easily folded in two stages. That is, in the cross-sectional shape of the holding lip portion 33, on the opening side of the mounting base portion 31 in the holding lip portion 33, than the line connecting the position of the vehicle inner side wall 31 b that becomes the root of the holding lip portion 30 and the first folding point 41. The line connecting the first fold point 41 and the second fold point 42 is inclined toward the bottom wall 31c side of the mounting base 31, and moreover than the line connecting the first fold point 41 and the second fold point 42. In addition, a line connecting the second folding point 42 and the position P at the outermost vehicle end at the tip of the holding lip 33 is inclined toward the bottom wall 31 c side of the mounting base 31.
Further, although the first folding point 41 to the second folding point 42 are flat, they may be formed so as to bulge and curve toward the opening side of the mounting base 31. Further, when flatly mounting from the second folding point 42 to the tip of the holding lip portion 33 and being attached to the flange 103 of the thin wall S, the entire flat surface is in close contact with the inner side surface of the flange 103.
第一折れ点４１の位置は、オープニングトリム３０がフランジ１０２に取付けられる前では、厚肉Ｔのフランジ１０２の車外側側面が突条部３２に摺接したときの、厚肉Ｔのフランジ１０２の車内側側面よりも車内側の位置に設定している。逆に厚肉Ｔのフランジ１０２の車内側側面よりも車外側の位置にすると保持リップ部３３の剛性が強くなりすぎるので車内側の位置の方が好ましい。
第二折れ点４２の位置は、オープニングトリム３０がフランジ１０３に取付けられる前では、薄肉Ｓのフランジ１０３の車外側側面が突条部３２に摺接したときの、薄肉Ｓのフランジ１０３の車内側側面よりも車外側の位置に設定している。なお、取付けた後でも第二折れ点４２の位置を、薄肉Ｓのフランジ１０３の車外側側面が突条部３２に摺接したときの、薄肉Ｓのフランジ１０３の車内側側面と車外側側面の間の位置に設定することが好ましい。
Before the opening trim 30 is attached to the flange 102, the position of the first folding point 41 is that of the thick T flange 102 when the outer side surface of the thick T flange 102 is in sliding contact with the protrusion 32. It is set to the position inside the car than the side inside the car. Conversely, if the position of the thick-walled flange 102 is on the vehicle outer side than the vehicle inner side surface, the holding lip portion 33 becomes too rigid, so the position on the vehicle inner side is preferable.
The position of the second folding point 42 is the vehicle inner side of the thin-walled S flange 103 when the outer side surface of the thin-walled flange 103 is in sliding contact with the ridge 32 before the opening trim 30 is attached to the flange 103. It is set at a position outside the vehicle from the side. Even after the mounting, the second folding point 42 is positioned at the vehicle inner side surface and the vehicle outer side surface of the thin S flange 103 when the vehicle outer side surface of the thin S flange 103 comes into sliding contact with the ridge 32. It is preferable to set it between the positions.
その上、保持リップ部３３の先端における底壁３１ｃ側を切り欠いて凹部３６を形成して先端の肉厚を薄くしている。
また、保持リップ部３３の断面形状において、保持リップ部３３における取付基部３１の底壁３１ｃ側（保持リップ部３３の裏面側）は、保持リップ部３０の付け根となる車内側側壁３１ｂの位置から凹部３６が形成された部位まで、取付基部３０の開口側（保持リップ部３３の表面側）に膨出湾曲する単一の曲面（曲率半径Ｒ）に形成されている。
In addition, a recess 36 is formed by cutting out the bottom wall 31c side at the tip of the holding lip 33 to reduce the thickness of the tip.
Further, in the cross-sectional shape of the holding lip portion 33, the bottom wall 31 c side (the back side of the holding lip portion 33) of the mounting base 31 in the holding lip portion 33 is from the position of the vehicle inner side wall 31 b that is the root of the holding lip portion 30. It is formed in the single curved surface (curvature radius R) which bulges and curves to the opening side (surface side of the holding lip part 33) of the attachment base 30 to the site | part in which the recessed part 36 was formed.
取付基部３１に埋設された芯材３４は、取付基部３１と同様に断面略Ｕ字形状であり、取付基部３１に沿って埋設されている。芯材３４としては、例えば、厚さ０．３ミリといった薄肉のものが使用され、金属製のものが使用されている。 The core member 34 embedded in the attachment base 31 has a substantially U-shaped cross section like the attachment base 31 and is embedded along the attachment base 31. As the core material 34, for example, a thin material having a thickness of 0.3 mm is used, and a metal material is used.
また、車内側側壁３１ａと底壁３１ｃとの連結位置には車内側に延びる断面略舌状の装飾リップ部３５が設けられている
オープニングトリム３０を構成する取付基部３１，突条部３２，保持リップ部３３及び装飾リップ部３５は、発泡材料、例えば、比重０．４〜０．８のＥＰＤＭやＴＰＥからなる発泡スポンジ材から形成されていて樹脂製の芯材３４とともにオープニングトリム３０全体の軽量化が図られている。
Further, a decorative lip portion 35 having a substantially tongue-like cross section extending inward of the vehicle is provided at the connecting position between the vehicle inner side wall 31a and the bottom wall 31c. The mounting base portion 31, the ridge portion 32, and the holding member constituting the opening trim 30 The lip portion 33 and the decorative lip portion 35 are formed of a foamed material, for example, a foamed sponge material made of EPDM or TPE having a specific gravity of 0.4 to 0.8, and together with the resin core material 34, the entire opening trim 30 is lightweight. It is planned.
次に、以上のように構成されたオープニングトリム３０をフランジに取付ける場合について説明する。
オープニングトリム３０が、板厚が厚肉Ｔのフランジ１０２に取付けられるとき、図２に示すように、取付基部３１の開口側からフランジ１０２が挿入されるように、フランジ１０２に対してオープニングトリム３０を近づけて（図２では上側に向けて）嵌め込んでいくと、保持リップ部３３は、第一折れ点４１を中心に第一折れ点４１より先の部分が取付基部３１の底壁３１ｃ側に向けて折れ曲がり、フランジ１０２の車内側側面に、保持リップ部３３の第一折れ点４１と第二折れ点４２の間の部位が摺接するとともに、フランジ１０２の車外側側面に、取付基部３１に設けられた突条部３２が摺接する。
そして、さらに、フランジ１０２に対してオープニングトリム３０を嵌め込んでいくと、図３に示すように、フランジ１０２は、保持リップ部３３の第一折れ点４１と第二折れ点４２の間の部位と、２つの突条部３２との間で挟持された状態となり、フランジ１０２にオープニングトリム３０が取付けられる。
Next, the case where the opening trim 30 comprised as mentioned above is attached to a flange is demonstrated.
When the opening trim 30 is attached to the flange 102 with the plate thickness T, as shown in FIG. 2, the opening trim 30 is inserted into the flange 102 so that the flange 102 is inserted from the opening side of the attachment base 31. 2 (closed upward in FIG. 2), the holding lip portion 33 is centered on the first folding point 41 and the portion ahead of the first folding point 41 is on the bottom wall 31 c side of the mounting base 31. The portion between the first fold point 41 and the second fold point 42 of the holding lip portion 33 is in sliding contact with the vehicle inner side surface of the flange 102, and the mounting base portion 31 is connected to the vehicle outer side surface of the flange 102. The provided ridge portion 32 is in sliding contact.
Then, when the opening trim 30 is further fitted into the flange 102, the flange 102 is located between the first folding point 41 and the second folding point 42 of the holding lip 33 as shown in FIG. The opening trim 30 is attached to the flange 102 by being sandwiched between the two protrusions 32.
このとき、保持リップ部３３から、第一折れ点４１を中心に折れ曲がった第一折れ点４１より先の部分が元に戻ろうとする反力が、第一折れ点４１と第二折れ点４２の間の部位からフランジ１０２に伝わり、フランジ１０２を突条部３２側に押圧するので、オープンニングトリム３０は安定した状態でフランジ１０２に取付けられる。また、オープンニングトリム３０の取付時には、保持リップ部３３は第一折れ点４１を中心に積極的に折れ曲がるので、板厚の厚いフランジ１０２であっても、取付基部３１の開口側から容易に挿入することができ、オープニングトリム３０を容易に嵌め込むことができる。
また、保持リップ部３３における取付基部３１の底壁３１ｃ側（裏面側）の側面は、取付基部３０の開口側（保持リップ部３３の表面側）に膨出湾曲する単一の曲面に形成されているので、オープニントリム３０の取付時に、保持リップ部３３と取付基部３１の車内側側壁３１ｂとの間には隙間Ｑが生じる。これにより、保持リップ部３３が、図３に示すように車内側側壁３１ｂ側に向けて大きく撓んでも、保持リップ部３３と車内側側壁３１ｂとの間には隙間Ｑがあるので、保持リップ部３３からの力が車内側側壁３１ｂに直接大きく伝わることはない。これにより、フランジ１０２に取付けられたオープニングトリム３０の取付基部３１の開口が広くなるといった、「口開き」の発生を防止することができる。
At this time, a reaction force from the holding lip portion 33 to return the portion ahead of the first folding point 41 bent around the first folding point 41 to the original is caused by the first folding point 41 and the second folding point 42. Since the flange 102 is transmitted to the flange 102 from the intermediate portion and presses the flange 102 toward the protrusion 32, the opening trim 30 is attached to the flange 102 in a stable state. Further, when the opening trim 30 is attached, the holding lip portion 33 is actively bent around the first folding point 41, so that even the thick flange 102 can be easily inserted from the opening side of the attachment base 31. The opening trim 30 can be easily fitted.
Further, the side surface on the bottom wall 31c side (rear surface side) of the mounting base portion 31 in the holding lip portion 33 is formed as a single curved surface that bulges and curves toward the opening side of the mounting base portion 30 (front surface side of the holding lip portion 33). Therefore, when the open trim 30 is attached, a gap Q is generated between the holding lip portion 33 and the vehicle interior side wall 31 b of the attachment base portion 31. Thereby, even if the holding lip portion 33 is greatly bent toward the vehicle inner side wall 31b as shown in FIG. 3, there is a gap Q between the holding lip portion 33 and the vehicle inner side wall 31b. The force from the portion 33 is not directly transmitted directly to the vehicle inner side wall 31b. Thereby, it is possible to prevent the occurrence of “opening” such that the opening of the mounting base 31 of the opening trim 30 attached to the flange 102 becomes wide.
また、保持リップ部３３の先端と底壁３１ｃの間にはわずかな隙間Ｎが残存する程度となっている。
そして、保持リップ部３３はスポンジ材であるため仮に保持リップ部３３が車内側側壁３１ｂと当接しても保持リップ部３３自体の撓みにより、「口開き」を防止する。これは、車内側側壁３１ｂもスポンジ材であれば、一層効果が大きい。
Further, a slight gap N remains between the tip of the holding lip 33 and the bottom wall 31c.
Since the holding lip portion 33 is a sponge material, even if the holding lip portion 33 comes into contact with the vehicle interior side wall 31b, the opening of the mouth is prevented by the bending of the holding lip portion 33 itself. This is even more effective if the vehicle interior side wall 31b is also a sponge material.
また、フランジ１０２にオープニングトリム３０を取付けるときに、保持リップ部３３の先端が対向する突条部３２に弾接することがあっても、突条部３２にはテーパー状の傾斜部３２ａが形成されているので、保持リップ部３３の先端は傾斜部３２ａに沿って円滑に車内側側壁３１ｂ側に撓む。これにより、フランジ１０２にオープニングトリム３０を取付けるときに、保持リップ部３３の先端が突条部３２側に引っ掛かり挿入荷重を急激に増大させるといった事態の発生を防止することができる。 Further, when the opening trim 30 is attached to the flange 102, even if the tip of the holding lip portion 33 may come into elastic contact with the opposing protruding portion 32, the protruding portion 32 is formed with a tapered inclined portion 32 a. Therefore, the front end of the holding lip portion 33 bends smoothly toward the vehicle interior side wall 31b along the inclined portion 32a. As a result, when the opening trim 30 is attached to the flange 102, it is possible to prevent a situation in which the tip of the holding lip 33 is caught on the ridge 32 side and the insertion load is rapidly increased.
次に、オープニングトリム３０が、板厚が薄肉Ｓのフランジ１０３に取付けられるとき、図４に示すように、保持リップ部３３は、第一折れ点４１を中心に第一折れ点４１より先の部分が取付基部３１の底壁３１ｃ側に向けて折れ曲がるとともに、第二折れ点４２を中心に第二折れ点４２より先の部分もフランジ１０２の車内側側面に折れ曲がり、フランジ１０３の車外側側面に、保持リップ部３３の先端と第二折れ点４２との間の部位が摺接する。
これにより、フランジ１０３は、保持リップ部３３の先端と第二折れ点４２の間の部位と、２つの突条部３２との間で挟持された状態となり、フランジ１０３にオープニングトリム３０が取付けられる。
Next, when the opening trim 30 is attached to the flange 103 having a thin plate S, the holding lip portion 33 is located at the first folding point 41 and the first folding point 41 as shown in FIG. The portion bends toward the bottom wall 31 c side of the mounting base portion 31, and the portion ahead of the second fold point 42 is also bent to the vehicle inner side surface of the flange 102 around the second fold point 42. The part between the tip of the holding lip 33 and the second folding point 42 is in sliding contact.
As a result, the flange 103 is sandwiched between the tip of the holding lip 33 and the second folding point 42 and the two protrusions 32, and the opening trim 30 is attached to the flange 103. .
このとき、保持リップ部３３から、第一折れ点４１を中心に折れ曲がった第一折れ点４１より先の部分が元に戻ろうとする反力に加えて、第二折れ点４２を中心に折れ曲がった第二折れ点４２より先の部分も元に戻ろうとする反力も、保持リップ部３３の先端と第二折れ点４２の間の部位から集中してフランジ１０３に伝わり、フランジ１０３を突条部３２側に押圧するので、オープンニングトリム３０は安定した状態でフランジ１０３に取付けられる。特に、保持リップ部３３の先端の取付基部３１の底壁３１ｃ側は切り欠かれていることにより、保持リップ部３３の先端の撓み量は大きく、しかも保持リップ部３３は発泡スポンジ材からなるので、保持リップ部３３の先端と第二折れ点４２の間の部位は、フランジ１０３の車内側側面に大きく密着した状態でくいつく。
よって、図５に示すように、オープニングトリム３０が薄肉Ｓのフランジ１０３に取付けられた状態からオープニングトリム３０を引き抜く方向（図５では下側）に力が作用しても、保持リップ部３３の先端と第二折れ点４２の間の部位に集中した反力がフランジ１０３にかかり突条部３２との間でフランジ１０３は強く挟持されるので、たとえ芯材３４として薄肉の金属製又は樹脂製のものを使用したとしてもフランジ１０３からオープニングトリム３０が容易に離れることはない。
しかも、保持リップ部３３の先端と第二折れ点４２の間は平担にされているので、フランジ１０３の車内側側面に摺接する保持リップ部３３の先端と第二折れ点４２の間の部位はフランジ１０３に対する密着度は高く一層保持力は向上する。
また、オープニングトリム３０の取付時には、保持リップ部３３は第一折れ点４１より先側が折れ曲がるとともに第二折れ点４２より先端も折れ曲がるので、板厚の薄いフランジ１０３を取付基部３１の開口側から容易に挿入することができ、オープニングトリム３０を容易に嵌め込むことができる。
At this time, in addition to the reaction force that the portion ahead of the first folding point 41 bent from the holding lip portion 33 centering on the first folding point 41 is bent back, the second folding point 42 is bent centered. The reaction force that tries to return the part beyond the second folding point 42 to the original is concentrated from the portion between the tip of the holding lip 33 and the second folding point 42 and is transmitted to the flange 103, and the flange 103 passes through the protrusion 32. The opening trim 30 is attached to the flange 103 in a stable state. In particular, since the bottom wall 31c side of the mounting base 31 at the tip of the holding lip 33 is cut away, the amount of bending at the tip of the holding lip 33 is large, and the holding lip 33 is made of a foamed sponge material. The portion between the front end of the holding lip 33 and the second folding point 42 clings to the side surface of the flange 103 in a state of being in great contact.
Therefore, as shown in FIG. 5, even if a force acts in a direction (lower side in FIG. 5) in which the opening trim 30 is pulled out from the state in which the opening trim 30 is attached to the thin-walled flange 103, the holding lip 33 Since the reaction force concentrated on the portion between the tip and the second folding point 42 is applied to the flange 103 and the flange 103 is strongly held between the protrusions 32, the core member 34 is made of a thin metal or resin. Even if one is used, the opening trim 30 is not easily separated from the flange 103.
In addition, since the gap between the tip of the holding lip 33 and the second folding point 42 is flat, a portion between the tip of the holding lip 33 and the second folding point 42 that is in sliding contact with the vehicle inner side surface of the flange 103. Has a high degree of adhesion to the flange 103 and further improves the holding power.
Further, when the opening trim 30 is attached, the holding lip portion 33 is bent at the front side from the first folding point 41 and the tip is also bent from the second folding point 42, so that the thin flange 103 can be easily formed from the opening side of the mounting base 31. The opening trim 30 can be easily fitted.
このように、本実施形態のオープニントリム３０によれば、板厚が厚肉Ｔのフランジ（例えば三枚重ねのもの）１０２から、薄肉Ｓのフランジ（例えば一枚のもの）１０３までオープニントリム３０を十分な保持力で取付けることができ、しかもフランジ１０２，１０３を取付基部３１の開口側から容易に挿入することができる。 As described above, according to the open trim 30 of the present embodiment, the open trim 30 from the flange (for example, three-layered) 102 having a thick wall thickness T to the flange (for example, one sheet) 103 having a thin S is provided. Can be attached with a sufficient holding force, and the flanges 102 and 103 can be easily inserted from the opening side of the attachment base 31.
そして、フランジ１０２，１０３に取付けられたオープニングトリム３０は、ドアの閉時にドア側に設けられた中空シール部（図示しない）に車外側側壁３１ａが弾接して車内外をシールするようになっている。なお、車外側側壁３１ａに中空シール部を設けて、ドアの閉時にドアに対してオープニングトリム側に設けられた中空シール部を弾接して車内側をシールするようにしてもよい。 The opening trim 30 attached to the flanges 102 and 103 seals the inside and outside of the vehicle with the vehicle outer side wall 31a elastically contacting a hollow seal portion (not shown) provided on the door side when the door is closed. Yes. A hollow seal portion may be provided on the vehicle outer side wall 31a, and the vehicle inner side may be sealed by elastically contacting the hollow seal portion provided on the opening trim side with respect to the door when the door is closed.
なお、本実施形態では、保持リップ部３３の先端と第二折れ点４２の間を平担にして特に板厚の薄肉Ｓのフランジ１０３に対して密着領域を広くした状態で摺接させたが、図６に示すように、保持リップ部３３の先端と第二折れ点４２の間を、取付基部３１の開口側に向けて膨出湾曲させるようにしてもよい。 In the present embodiment, the front end of the holding lip 33 and the second folding point 42 are flattened, and in particular, are brought into sliding contact with the flange 103 of the thin-walled sheet S with a wide contact area. As shown in FIG. 6, the tip of the holding lip 33 and the second folding point 42 may be bulged and curved toward the opening side of the mounting base 31.
また、本実施形態では、保持リップ部３３の先端の剛性を底壁３１ｃ側を切り欠くことによって保持リップ部３３の他の部位の剛性よりも低くして保持リップ部３３の先端の撓み量を増加させたが、図７に示すように、特に切り欠きを設けることなく、保持リップ部３３の先端の剛性が保持リップ部３３の他の部位の剛性よりも低くなるような材質で保持リップ部３３の先端を形成してもよい。 Further, in the present embodiment, the rigidity of the tip of the holding lip 33 is made lower than the rigidity of other parts of the holding lip 33 by cutting out the rigidity of the tip of the holding lip 33 so as to cut the bottom wall 31c side. As shown in FIG. 7, the holding lip portion is made of a material such that the rigidity of the tip of the holding lip portion 33 is lower than the rigidity of other portions of the holding lip portion 33 without providing a notch. 33 tips may be formed.
また、本実施形態では、保持リップ部３３における取付基部３１の開口側に第一折れ点４１を設けたが、これにかえて、図８に示すように、保持リップ部３３における取付基部３１の底壁３１ｃ側でしかも車内側側壁３１ｂ側にノッチ３７やスリットを設けるようにしてもよい。 In the present embodiment, the first folding point 41 is provided on the opening side of the mounting base 31 in the holding lip 33. Instead, as shown in FIG. 8, the mounting base 31 in the holding lip 33 is provided. You may make it provide the notch 37 and the slit in the bottom wall 31c side and the vehicle inner side wall 31b side.
また、本実施形態では、保持リップ部３３における取付基部３１の底壁３１ｃ側（保持リップ部３３の裏面側）で、保持リップ部３３の付け根となる車内側側壁３１ｂの位置から凹部３６が形成された部位までを、取付基部３０の開口側（保持リップ部３３の表面側）に膨出湾曲する単一の曲面（曲率半径Ｒ）に形成したが、取付基部３０の開口側（保持リップ部３３の表面側）に膨出湾曲する形状であれば、オープニントリム３０の取付時に、保持リップ部３３と取付基部３１の車内側側壁３１ｂとの間に隙間Ｑを生じさせ、保持リップ部３３からの力が車内側側壁３１ｂに直接大きく伝わることは防止されるので、必ずしも単一の曲面でなくてもよい。
また、本実施形態では、オープニングトリム３０において芯材３４を除いたすべての部分を発泡スポンジ材で構成したが、保持リップ部３３だけ、あるいは、フランジ１０２，１０３を直接挟持する突条部３２と保持リップ部３３だけを発泡スポンジ材で構成するようにしても十分な保持力が得られる。
また、本実施形態では、芯材３４としては、例えば、厚さ０．３ミリといった薄肉のものを使用したが、厚肉のものを使用してもよいし、金属製のものに限らず樹脂製のものを使用することも可能である。
Further, in the present embodiment, the concave portion 36 is formed from the position of the vehicle interior side wall 31b that becomes the root of the holding lip portion 33 on the bottom wall 31c side (the back surface side of the holding lip portion 33) of the mounting base portion 31 in the holding lip portion 33. Up to the formed portion is formed into a single curved surface (curvature radius R) that bulges and curves toward the opening side of the mounting base 30 (the surface side of the holding lip 33), but the opening side (holding lip portion) of the mounting base 30 If the opening trim 30 is attached, a gap Q is generated between the holding lip portion 33 and the vehicle interior side wall 31b of the attachment base portion 31 so that the holding lip portion 33 Is prevented from being directly transmitted to the vehicle inner side wall 31b, so that it does not necessarily have to be a single curved surface.
In the present embodiment, all the portions of the opening trim 30 excluding the core material 34 are made of foamed sponge material, but only the holding lip portion 33 or the ridge portion 32 that directly holds the flanges 102 and 103 and Even if only the holding lip portion 33 is made of a foamed sponge material, a sufficient holding force can be obtained.
Further, in this embodiment, as the core material 34, for example, a thin material having a thickness of 0.3 mm is used. However, a thick material may be used, and the material is not limited to a metal material. It is also possible to use the one made of.
