Description

本発明は、ガラスランに関するものである。   The present invention relates to a glass run.

一般に、自動車のドアには、ドアフレームの内周に沿ってガラスランが設けられている。ガラスランは、その長手方向に直交する断面方向から見ると、基底部と、該基底部から延びる車内側側壁部及び車外側側壁部とを具備する断面略コ字形の本体部を備えるとともに、両側壁部の先端からそれぞれ本体部の内側に向けて延びる車内側シールリップ及び車外側シールリップを備えている。上記ガラスランは、前記本体部がドアフレームの内周に沿って設けられた取付部に取着され、両シールリップによって、昇降するドアガラスの内外面の周縁部が挟まれるようにしてシールされる。   Generally, a glass run is provided on the door of an automobile along the inner periphery of the door frame. The glass run has a substantially U-shaped cross section including a base portion, a vehicle inner side wall portion and a vehicle outer side wall portion extending from the base portion when viewed from a cross-sectional direction perpendicular to the longitudinal direction, and both sides. A vehicle interior seal lip and a vehicle exterior seal lip extending from the tip of the wall portion toward the inside of the main body portion are provided. The glass run is sealed so that the body portion is attached to a mounting portion provided along the inner periphery of the door frame, and the peripheral portions of the inner and outer surfaces of the door glass moving up and down are sandwiched by both seal lips. The

また、従来、一般的な取付部は、ドアフレームを構成するアウタパネルの端縁で構成される車外側フランジ部と、インナパネルの端縁で構成される車内側フランジ部と、車外側フランジ部と車内側フランジ部との間に設けられる断面略コ字状のチャンネル部材とを備えている。これに対し、近年、軽量化及び低コスト化を図るべく、チャンネル部材が省略されたものも見受けられる。このようなドア（所謂プレスドア）に取付けられるガラスランは、車内側側壁部及び車外側側壁部の先端から本体部の外側に延びる車内側意匠リップ及び車外側意匠リップを備えている。そして、本体部が一対のフランジ部の間に押込まれ、車内側意匠リップと車内側側壁部とで車内側フランジ部が挟み込まれるとともに、車外側意匠リップと車外側側壁部とで車外側フランジ部が挟み込まれることで、ガラスランが取付部に取付けられている（例えば、特許文献１等参照。）。   Conventionally, a general mounting portion includes an outer flange portion configured by an end edge of an outer panel constituting a door frame, an inner flange portion configured by an end edge of an inner panel, and an outer flange portion. A channel member having a substantially U-shaped cross section provided between the inner flange portion and the vehicle inner flange portion. On the other hand, in recent years, some channel members have been omitted in order to reduce weight and cost. A glass run attached to such a door (so-called press door) includes a vehicle interior design lip and a vehicle exterior design lip extending from the front ends of the vehicle interior side wall and the vehicle exterior side wall to the outside of the main body. The main body portion is pushed between the pair of flange portions, and the vehicle interior flange portion is sandwiched between the vehicle interior design lip and the vehicle interior side wall portion, and the vehicle exterior flange portion is formed between the vehicle exterior design lip and the vehicle exterior side wall portion. As a result, the glass run is attached to the attachment portion (see, for example, Patent Document 1).

特許第４１４５２３３号公報Japanese Patent No. 4145233

しかしながら、上記ドアに関しては、チャンネル部材でガラスランの基底部を支持することができないため、ドアガラスが上昇して窓部が閉鎖される際に、ガラスランの上辺部の基底部がドアガラスに突き上げられ、上方に変位してしまうおそれがある。この場合、一対の側壁部についても追従して上方に変位してしまい、これに伴って、一対の意匠リップがそれぞれフランジ部から離間するようにして変形（口開き）してしまうおそれがある。この場合、外観品質の低下等を招くことが懸念される。   However, with respect to the door, since the base portion of the glass run cannot be supported by the channel member, when the door glass rises and the window portion is closed, the base portion of the upper side of the glass run becomes the door glass. There is a risk of being pushed up and displaced upward. In this case, the pair of side wall portions also follow and are displaced upward, and accordingly, the pair of design lips may be deformed (opened) so as to be separated from the flange portion. In this case, there is a concern that the appearance quality may be deteriorated.

本発明は、上記例示した問題点等を解決するためになされたものであって、その目的は、ドア窓部を閉鎖した際の意匠リップの変形を防止することのできるガラスランを提供することにある。   The present invention has been made to solve the above-mentioned problems and the like, and its purpose is to provide a glass run that can prevent the deformation of the design lip when the door window is closed. It is in.

以下、上記目的等を解決するのに適した各手段につき項分けして説明する。なお、必要に応じて対応する手段に特有の作用効果等を付記する。   In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

A body portion having a substantially U-shaped cross section comprising a base portion and a pair of opposite vehicle inner side wall portions and vehicle outer side wall portions extending in a direction intersecting the base portion;
A vehicle inner side seal lip and a vehicle outer side seal lip extending from substantially the front ends of the vehicle inner side wall portion and the vehicle outer side wall portion toward the inside of the main body portion;
Regarding the frame corresponding part provided above the belt line of the door,
A vehicle interior design lip and a vehicle exterior design lip extending from substantially the front end of the vehicle interior side wall and the vehicle exterior side wall toward the outside of the main body,
The main body portion is pushed between the vehicle interior flange portion and the vehicle exterior flange portion that are provided along the inner periphery of the door frame, and the vehicle interior flange is formed by the vehicle interior side wall portion and the vehicle interior design lip. A glass run that is attached along the inner periphery of the door frame by sandwiching the vehicle outer flange portion between the vehicle outer side wall portion and the vehicle outer design lip,
Regarding the upper side of the glass run provided corresponding to the upper edge of the door glass,
A vehicle inner side connecting portion that connects between the ends of the base portion and the vehicle inner side wall portion;
A vehicle outer side connecting portion that connects between the base portion and the end portion of the vehicle outer side wall portion;
The vehicle interior connection portion and the vehicle exterior connection portion are:
A first connection side portion extending from the outer peripheral side end portion of the vehicle inner side wall portion and the outer side wall portion to the outer peripheral side of the main body portion and thinner than the side wall portions, and
A second connecting side portion extending from the distal end portion of the first connecting side portion to the base portion side and the inner peripheral side of the main body portion;
A glass run, comprising: a third connecting side portion extending from an end portion of the second connecting side portion to the outer peripheral side of the main body portion and connected to an end portion of the base portion.

手段１によれば、ドアガラスでドア窓部を閉鎖した場合に、ガラスラン上辺部の基底部がドアガラスによって押し上げられたとしても、車内側連結部及び車外側連結部が追従的に上方に伸長するようにして変形することとなる。このため、基底部の変位に起因する応力が車内側側壁部及び車外側側壁部に対してほとんど及ばないようにすることができる。従って、ドアガラスによって押し上げられた基底部とともに一対の側壁部が上方に引っ張られて上方に変位してしまうことに起因して、一対の意匠リップが本体部の外方に広がるようにして変形（口開き）してしまうといった懸念を払拭することができる。結果として、ドア窓部の閉鎖時等において、意匠リップがフランジ部から離間してしまうことを防止することができ、外観品質の向上を図ることができる。   According to the means 1, when the door window portion is closed with the door glass, even if the base portion of the upper side of the glass run is pushed up by the door glass, the vehicle inner side connection portion and the vehicle outer side connection portion follow upward. It will be deformed as it expands. For this reason, the stress resulting from the displacement of the base portion can be hardly applied to the vehicle inner side wall portion and the vehicle outer side wall portion. Accordingly, the pair of side wall portions are pulled upward together with the base portion pushed up by the door glass and displaced upward, so that the pair of design lips are deformed so as to spread outward of the main body portion ( It is possible to eliminate the concern that the mouth will open. As a result, it is possible to prevent the design lip from being separated from the flange portion when the door window portion is closed, and the appearance quality can be improved.

特に、本手段によれば、車内側及び車外側の両方に同様の連結部が設けられているため、車内側意匠リップ及び車外側意匠リップの両方に関して上記作用効果が奏されることとなる。さらに、例えば、連結部が車内側又は車外側のどちらか一方だけに設けられている場合に比べ、ドアガラスによって基底部が押圧された際に、傾倒した基底部によってドアガラスが車内側又は車外側に不要に変位させられてしまうといった事態を回避することができる。   In particular, according to this means, since the same connecting portion is provided on both the vehicle interior side and the vehicle exterior side, the above-described effects can be achieved with respect to both the vehicle interior design lip and the vehicle exterior design lip. Further, for example, when the base portion is pressed by the door glass, the door glass is tilted by the tilted base portion, compared to the case where the connecting portion is provided only on either the vehicle inner side or the vehicle outer side. It is possible to avoid such a situation that the outer side is unnecessarily displaced.

また、本手段では、第１連結辺部は、側壁部から本体部の外周側に延出している。このため、ガラスラン上辺部の基底部が上方に相対変位する際に、第１連結辺部を側方に開くように傾倒させつつ、連結部を上方に伸長変形させる（第２連結辺部をドアフレーム外周側に向けて傾倒させる）ことができる。すなわち、例えば、第１連結辺部が本体部内周側に延出している場合には、連結部を上方に伸長変形させようとしても、連結部の左右方向への変位を許容するような余地がないことから、第１連結辺部や第３連結辺部を無理やりに中間部位から屈曲変形させない限り、連結部を上方に伸長させることができない。これでは、連結辺部への負担が大きく、連結辺部が破れてしまうおそれがある。さらには、伸長変形したとしても、ドアガラスが基底部から離間して、ドアガラスからの応力が解除されたにもかかわらず、自身の弾性力では伸長変形前の元の断面形状に戻れないようになってしまうことが懸念される。この点、本手段のように、第１連結辺部を側壁部から本体部外周側に延出させ、連結部を伸長変形させる際に、連結辺部の中間部位を屈曲させることなく、連結部位においてスムースに展開させる構成を採用することにより、上記不具合を払拭することができる。   Moreover, in this means, the 1st connection side part is extended to the outer peripheral side of the main-body part from the side wall part. For this reason, when the base part of the upper side of the glass run is relatively displaced upward, the connecting part is extended and deformed upward while tilting the first connecting side to open sideways (the second connecting side is Tilting toward the outer periphery of the door frame). That is, for example, when the first connecting side portion extends to the inner peripheral side of the main body portion, there is room for allowing displacement in the left-right direction of the connecting portion even if the connecting portion is extended and deformed upward. Therefore, the connecting portion cannot be extended upward unless the first connecting side portion and the third connecting side portion are forcibly bent and deformed from the intermediate portion. This places a heavy burden on the connecting side and may break the connecting side. Furthermore, even if the door glass is extended and deformed, the elastic force of the door glass does not return to the original cross-sectional shape before the extension deformation even though the door glass is separated from the base and the stress from the door glass is released. There is a concern that it will become. In this regard, as in this means, when the first connecting side portion is extended from the side wall portion to the outer peripheral side of the main body portion and the connecting portion is extended and deformed, the connecting portion is not bent without bending the intermediate portion of the connecting side portion. By adopting a structure that smoothly develops in the above, the above-mentioned problems can be eliminated.

さらに、例えば、連結部が第１連結辺部及び第２連結辺部のみで構成される場合において、各連結辺部が短過ぎる場合、伸縮変形量が小さくなり、ドアガラスによってガラスラン上辺部の基底部が押し上げられた場合に、連結部の変形許容量を超えてしまい、側壁部が上方に変位してしまったり、連結部が損傷したりするおそれがある。その一方で、各連結辺部が長過ぎる場合、本体部の断面形状を維持し難くなってしまうことが懸念される。   Furthermore, for example, in the case where the connecting portion is composed of only the first connecting side portion and the second connecting side portion, if each connecting side portion is too short, the amount of expansion / contraction deformation is reduced, and the door glass causes the upper side portion of the glass run. When the base portion is pushed up, the allowable deformation amount of the connecting portion is exceeded, and the side wall portion may be displaced upward or the connecting portion may be damaged. On the other hand, when each connection side part is too long, we are anxious about maintaining the cross-sectional shape of a main-body part.

この点、第１連結辺部及び第２連結辺部だけでなく、第３連結辺部をも備えることで、各連結辺部が長過ぎてしまうことを回避しつつ、第１連結辺部及び第２連結辺部の損傷等を防止することができる。また、基底部をよりフレキシブルに変位可能にすることができる。すなわち、ドアガラスが基底部に対してイレギュラーな当たり方（例えば、搭乗者がドアガラスを押圧した状態でドアガラスが閉鎖される等）をしても十分に対処することができる。   In this respect, by providing not only the first connection side and the second connection side, but also the third connection side, the first connection side and It is possible to prevent the second connecting side from being damaged. Moreover, the base part can be displaced more flexibly. That is, even if the door glass is irregularly contacted with respect to the base portion (for example, the door glass is closed in a state where the passenger presses the door glass), it can be sufficiently dealt with.

手段２．前記第１連結辺部と前記第２連結辺部との連結部位における厚みは、前記第２連結辺部と前記第３連結辺部との連結部位における厚みよりも薄いことを特徴とする手段１に記載のガラスラン。   Mean 2. The thickness of the connecting portion between the first connecting side portion and the second connecting side portion is thinner than the thickness of the connecting portion between the second connecting side portion and the third connecting side portion. The glass run described in 1.

手段２によれば、第２連結辺部と第３連結辺部との連結部位よりも、第１連結辺部と第２連結辺部との連結部位をより積極的に変形させることができる。これにより、連結部を上方に伸長変形させる際に、第１連結辺部をよりスムースに側方に開くようにして変形させ、第２連結辺部をドアフレーム外周側に向けてよりスムースに傾倒変形させることができる。   According to the means 2, the connection part of the first connection side part and the second connection side part can be deformed more positively than the connection part of the second connection side part and the third connection side part. Accordingly, when the connecting portion is extended and deformed upward, the first connecting side portion is deformed so as to open more smoothly to the side, and the second connecting side portion is inclined more smoothly toward the door frame outer peripheral side. Can be deformed.

手段３．ガラスラン上辺部の前記基底部がドアガラスによって押圧されていない状態において、前記基底部の前記本体部外周側面と、前記車内側連結部の前記第１連結辺部と前記第２連結辺部との連結部位と、前記車外側連結部の前記第１連結辺部と前記第２連結辺部との連結部位とが、仮想の同一直線上にほぼ位置することを特徴とする手段１又は２に記載のガラスラン。   Means 3. In a state where the base portion of the glass run upper side portion is not pressed by the door glass, the main body portion outer peripheral side surface of the base portion, the first connection side portion and the second connection side portion of the vehicle interior connection portion, The connecting portion between the first connecting side portion and the second connecting side portion of the vehicle outer side connecting portion is substantially located on an imaginary straight line. The glass run described.

手段３によれば、例えば、左右の連結部の第１連結辺部と第２連結辺部との連結部位が、基底部よりも大幅に本体部外周側に突出位置している場合に比べ、本体部の断面形状を維持し易くすることができる。さらに、第１連結辺部及び第２連結辺部がガラスランとは別の部材に当接してしまって、連結部の変形動作等に支障を来してしまうといった事態を回避することができる。また、例えば、基底部が、左右の連結部の第１連結辺部と第２連結辺部との連結部位よりも大幅に本体部外周側に突出位置している場合に比べ、基底部が側壁部から上方に離間し過ぎてしまうといった事態を回避しつつ、連結部の各連結辺部の長さを十分に確保することができる。   According to the means 3, for example, compared to the case where the connection part of the first connection side and the second connection side of the left and right connection parts protrudes significantly to the outer peripheral side of the main body part from the base part, The cross-sectional shape of the main body can be easily maintained. Furthermore, it is possible to avoid a situation in which the first connecting side portion and the second connecting side portion are in contact with a member different from the glass run, which hinders the deformation operation or the like of the connecting portion. In addition, for example, the base portion is a side wall as compared with the case where the base portion protrudes to the outer peripheral side of the main body portion significantly than the connection portion between the first connection side portion and the second connection side portion of the left and right connection portions. The length of each connecting side portion of the connecting portion can be sufficiently ensured while avoiding the situation of being too far apart from the portion.

手段４．前記第３連結辺部は前記第１連結辺部よりも厚肉に構成され、
前記車内側連結部及び前記車外側連結部のうち少なくとも一方に関し、前記第２連結辺部と前記第３連結辺部との連結部位は、ガラスラン上辺部の前記基底部がドアガラスによって押圧されていない状態では、ドアガラスの昇降方向に対して交差する方向において対応する前記側壁部と略当接していることを特徴とする手段１乃至３のいずれかに記載のガラスラン。 Means 4. The third connection side is configured to be thicker than the first connection side,
Regarding at least one of the vehicle interior connection portion and the vehicle exterior connection portion, the base portion of the upper side of the glass run is pressed by the door glass at the connection portion of the second connection side portion and the third connection side portion. The glass run according to any one of means 1 to 3, wherein the glass run is substantially in contact with the corresponding side wall portion in a direction intersecting with the raising / lowering direction of the door glass when the door glass is not.

手段４によれば、ドアガラスの昇降方向に対して交差する方向（左右方向）における基底部の位置ずれを抑制することができる。その一方で、側壁部の基端部側が本体部内周側に傾倒することを抑制することができる。   According to the means 4, the position shift of the base part in the direction (left-right direction) which cross | intersects with respect to the raising / lowering direction of a door glass can be suppressed. On the other hand, it can suppress that the base end part side of a side wall part inclines to a main-body part inner peripheral side.

ドアの概略構成を示す正面模式図である。It is a front schematic diagram which shows schematic structure of a door. 図１のＪ−Ｊ線断面図である。It is the JJ sectional view taken on the line of FIG. ドアガラスが窓部閉鎖時の正規位置にある状態のガラスランを示す断面図である。It is sectional drawing which shows the glass run of the state which has a door glass in the normal position at the time of window part closing. 基底部がドアガラスによって突上げられた状態にあるガラスランを示す断面図である。It is sectional drawing which shows the glass run in the state by which the base part was pushed up with the door glass.

以下に、一実施形態について図面を参照しつつ説明する。図１に示すように、自動車のドア用開口部に開閉可能に設けられるフロントドア（以下、単に「ドア１」と称する）には、ドア１の窓部Ｗを開閉する昇降可能なドアガラスＧと、当該ドアガラスＧの外周形状に対応して設けられ、ドアガラスＧの昇降を案内するとともに、窓部Ｗを画定するドアフレーム２とドアガラスＧの周縁部との間をシールするガラスラン４とが設けられている。   Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIG. 1, a front door (hereinafter simply referred to as “door 1”) that can be opened and closed at an opening for a door of an automobile has a door glass G that can be raised and lowered to open and close a window W of the door 1. And a glass run that is provided corresponding to the outer peripheral shape of the door glass G, guides the raising and lowering of the door glass G, and seals between the door frame 2 defining the window W and the peripheral edge of the door glass G. 4 are provided.

ガラスラン４は、ドアガラスＧの上縁部に対応する押出成形部５、ドアガラスＧの前後の縦縁部に対応する押出成形部６、７と、押出成形部５−６、５−７の端末部同士を接続する型成形部８、９とを備えている。各押出成形部５〜７は、図示しない押出成形機によりほぼ直線状に形成される。型成形部８、９は、２つの押出成形部５−６、５−７が所定の角度をなした状態で相互に接続されるように図示しない金型装置にて接続成形される。そして、ドアフレーム２の内周に沿って形成されるサッシュ部ＤＳ、及びサッシュ部ＤＳの前後の縦辺部を下方に延長するようにしてドアパネル３内に設けられたチャンネル部ＤＣに当該ガラスラン４が取付けられている。本実施形態におけるガラスラン４は、ＥＰＤＭ（エチレン−プロピレン−ジエン共重合ゴム）により構成されている。   The glass run 4 includes an extrusion molding portion 5 corresponding to the upper edge portion of the door glass G, extrusion molding portions 6 and 7 corresponding to the front and rear vertical edge portions of the door glass G, and extrusion molding portions 5-6 and 5-7. Mold forming portions 8 and 9 for connecting the terminal portions of the two. Each extrusion-molding part 5-7 is formed in the substantially linear form with the extruder which is not shown in figure. The mold forming sections 8 and 9 are connected and molded by a mold apparatus (not shown) so that the two extruded sections 5-6 and 5-7 are connected to each other at a predetermined angle. The sash portion DS formed along the inner periphery of the door frame 2 and the channel portion DC provided in the door panel 3 so as to extend downward in the longitudinal direction of the front and back of the sash portion DS, 4 is attached. The glass run 4 in the present embodiment is composed of EPDM (ethylene-propylene-diene copolymer rubber).

図２に示すように、押出成形部５が取付けられるサッシュ部ＤＳは、ドアフレーム２等を構成するインナパネル３１、及び、アウタパネル３２の端部をそれぞれ窓部Ｗの内周側（図２では下側）に折り曲げることで形成された車内側フランジ部３３、及び、車外側フランジ部３４によって構成されている。すなわち、サッシュ部ＤＳは、車内側フランジ部３３及び車外側フランジ部３４間に略コ字状のチャンネル部材を介在させない構成（チャンネルレス構造）となっている。これにより、軽量化及びコストの削減等が図られている。   As shown in FIG. 2, the sash portion DS to which the extrusion molding portion 5 is attached has an inner panel 31 and an outer panel 32 constituting the door frame 2 and the like, and the end portions of the outer panel 32 are respectively on the inner peripheral side of the window portion W (in FIG. 2). It is comprised by the vehicle inner side flange part 33 and the vehicle outer side flange part 34 which were formed by bending to the lower side. That is, the sash portion DS has a configuration in which a substantially U-shaped channel member is not interposed between the vehicle inner flange portion 33 and the vehicle outer flange portion 34 (channelless structure). Thereby, weight reduction and cost reduction are achieved.

一方、押出成形部５は、断面略コ字状をなし、ドアフレーム２内周側に開口する向きでサッシュ部ＤＳに嵌め込まれる本体部１１と、本体部１１の開口側端縁から本体部１１の内側に延出する車内側シールリップ１２及び車外側シールリップ１３と、本体部１１の開口側端縁から本体部１１の外側に延出する車内側意匠リップ１４及び車外側意匠リップ１５とを備えている。そして、本体部１１を車内側フランジ部３３と車外側フランジ部３４との間に嵌め込むことで、車内側フランジ部３３が車内側側壁部１８と車内側意匠リップ１４とで挟み込まれるとともに、車外側フランジ部３４が車外側側壁部１９と車外側意匠リップ１５とで挟み込まれる。これにより、押出成形部５がサッシュ部ＤＳに取付けられている。さらに、ドアガラスＧにより窓部Ｗが閉鎖された状態においては、車内側シールリップ１２がドアガラスＧの車内側面に圧接され、車外側シールリップ１３がドアガラスＧの車外側面に圧接される。これにより、ドアガラスＧの車内側及び車外側がそれぞれシールされるようになっている。   On the other hand, the extrusion molding part 5 has a substantially U-shaped cross section, and the main body part 11 fitted into the sash part DS in a direction opening toward the inner peripheral side of the door frame 2, and the main body part 11 from the opening side edge of the main body part 11. A vehicle interior seal lip 12 and a vehicle exterior seal lip 13 extending inward of the vehicle body, and a vehicle interior design lip 14 and vehicle exterior design lip 15 extending from the opening side edge of the main body 11 to the outside of the main body 11. I have.

また、車内側連結部２２において、第１連結辺部２２ａと第２連結辺部２２ｂとの連結部位における厚みは、第２連結辺部２２ｂと第３連結辺部２２ｃとの連結部位における厚みよりも薄く構成されている。さらに、車外側連結部２３において、第１連結辺部２３ａと第２連結辺部２３ｂとの連結部位における厚みは、第２連結辺部２３ｂと第３連結辺部２３ｃとの連結部位における厚みよりも薄く構成されている。加えて、第３連結辺部２２ｃ、２３ｃは、対応する第１連結辺部２２ａ、２３ａよりも厚肉に構成されており、本実施形態では、基底部１７とほぼ同じ厚みを有している。   Moreover, in the vehicle interior side connection part 22, the thickness in the connection part of the 1st connection side part 22a and the 2nd connection side part 22b is more than the thickness in the connection part of the 2nd connection side part 22b and the 3rd connection side part 22c. It is also made thin. Furthermore, in the outside connection part 23, the thickness at the connection part between the first connection side part 23a and the second connection side part 23b is larger than the thickness at the connection part between the second connection side part 23b and the third connection side part 23c.

On the other hand, the first connection side portion 23a of the vehicle outer side connection portion 23 is configured to be thinner than the vehicle outer side wall portion 19 and extends from the vehicle outer side portion of the door frame 2 outer peripheral side end surface of the vehicle outer side wall portion 19. ing. Furthermore, the door frame 2 outer peripheral side end surface of the vehicle inner side wall portion 18 extends upwardly inclined toward the vehicle inner side. On the other hand, the door frame 2 outer peripheral side end surface of the vehicle outer side wall portion 19 extends upwardly inclined toward the vehicle outer side.

本実施形態では、図２に示すように、押出成形部５の基底部１７がドアガラスＧによって押圧されていない状態では、車内側側壁部１８のドアフレーム２外周側端面と、車内側連結部２２の第２連結辺部２２ｂと第３連結辺部２２ｃとの連結部位とが、ドアガラスＧの昇降方向に対して交差する方向（左右方向）において略当接している。また、車外側の部位に関しては、車外側側壁部１９のドアフレーム２外周側端面と、車外側連結部２３の第２連結辺部２３ｂと第３連結辺部２３ｃとの連結部位とが、ドアガラスＧの昇降方向に対して交差する方向（左右方向）において対向している。さらに、押出成形部５の基底部１７がドアガラスＧによって押圧されていない状態において、基底部１７の本体部１１外周側面（上面）と、車内側連結部２２の第１連結辺部２２ａと第２連結辺部２２ｂとの連結部位と、車外側連結部２３の第１連結辺部２３ａと第２連結辺部２３ｂとの連結部位とが、仮想の同一直線Ｘ上にほぼ位置するように構成されている。   In the present embodiment, as shown in FIG. 2, in a state where the base portion 17 of the extrusion molding portion 5 is not pressed by the door glass G, the door frame 2 outer peripheral side end surface of the vehicle interior side wall portion 18 and the vehicle interior connection portion. The connection part of 22nd 2nd connection edge part 22b and 3rd connection edge part 22c is substantially contact | abutting in the direction (left-right direction) which cross | intersects with respect to the raising / lowering direction of the door glass G. Further, with respect to the vehicle outer side portion, the door frame 2 outer peripheral side end surface of the vehicle outer side wall portion 19 and the connection portion of the second connection side portion 23b and the third connection side portion 23c of the vehicle outer side connection portion 23 are the door. Opposing in the direction (left-right direction) intersecting with the raising and lowering direction of the glass G. Furthermore, in a state where the base portion 17 of the extrusion molding portion 5 is not pressed by the door glass G, the outer peripheral side surface (upper surface) of the base portion 11 of the base portion 17, the first connection side portion 22 a of the vehicle inner side connection portion 22, and the first side. The connection portion between the two connection side portions 22b and the connection portion between the first connection side portion 23a and the second connection side portion 23b of the vehicle outer side connection portion 23 are substantially located on the virtual same straight line X. Has been.

加えて、本体部１１の内側には、車内側連結部２２の第２連結辺部２２ｂと第３連結辺部２２ｃとの連結部位から車外側に延出する内リップ２５が設けられている。当該内リップ２５は、基底部１７の内側面のうちドアガラスＧと当接する部位を覆うようにして設けられている。図３に示すように、内リップ２５は、窓部Ｗを閉鎖したドアガラスＧによって押し上げられると、基底部１７との間に中空部を形成するようにして、車外側連結部２３の第２連結辺部２３ｂと第３連結辺部２３ｃとの連結部位と当接するようになっている。このように内リップ２５が設けられることによって、遮音性やシール性の向上を図ることができる。   In addition, an inner lip 25 is provided on the inner side of the main body portion 11 so as to extend from the connection portion between the second connection side portion 22b and the third connection side portion 22c of the vehicle inner side connection portion 22 to the vehicle outer side. The inner lip 25 is provided so as to cover a portion of the inner side surface of the base portion 17 that contacts the door glass G. As shown in FIG. 3, when the inner lip 25 is pushed up by the door glass G with the window W closed, a second hollow portion is formed between the inner lip 25 and the base portion 17. The connection side part 23b and the 3rd connection side part 23c contact | abut the connection site | part. By providing the inner lip 25 in this way, it is possible to improve sound insulation and sealing performance.

また、ドアガラスＧが比較的勢いよく上昇して窓部Ｗが閉鎖される際には、ドアガラスＧの上縁部が内リップ２５に衝突する。この場合、図４に示すように、基底部１７がドアガラスＧによって内リップ２５を介して上方に押し上げられるとともに、基底部１７の上方への変位に伴って、車内側連結部２２及び車外側連結部２３が追従的に上方に伸長変形する。このため、車内側側壁部１８及び車外側側壁部１９には、基底部１７が上方に変位したことに起因する応力、すなわち、上方に持ち上げられるような力がほとんど作用しないようになっている。   Further, when the door glass G rises relatively vigorously and the window portion W is closed, the upper edge portion of the door glass G collides with the inner lip 25. In this case, as shown in FIG. 4, the base portion 17 is pushed upward by the door glass G through the inner lip 25, and as the base portion 17 is displaced upward, the vehicle inner side connection portion 22 and the vehicle outer side are provided. The connecting portion 23 extends and deforms upward in a follow-up manner. For this reason, on the vehicle inner side wall portion 18 and the vehicle outer side wall portion 19, stress caused by the displacement of the base portion 17, that is, a force that lifts upward is hardly applied.

特に、本実施形態の車内側連結部２２及び車外側連結部２３は、折り畳まれるようにして設けられている第１連結辺部２２ａ、２３ａ、第２連結辺部２２ｂ、２３ｂ、及び、第３連結辺部２２ｃ、２３ｃが展開するようにして伸長変形する。より具体的には、第１連結辺部２２ａ、２３ａが側方に開くようにして傾倒変位しつつ、第１連結辺部２２ａ、２３ａと第２連結辺部２２ｂ、２３ｂとのなす角度を広げるようにして、第２連結辺部２２ｂ、２３ｂがドアフレーム２外周側に向けて傾倒変位する。これにより、第１連結辺部２２ａ、２３ａ、第２連結辺部２２ｂ、２３ｂ、及び、第３連結辺部２２ｃ、２３ｃが各中間位置において屈曲されたり、基底部１７が左右に変位したりすることなく、連結部２２、２３を比較的スムースに上方に伸長させ、側壁部１８、１９には影響が及ばないように、基底部１７を比較的スムースに上方に変位させることができる。   In particular, the vehicle interior coupling portion 22 and the vehicle exterior coupling portion 23 of the present embodiment are provided with a first coupling side portion 22a, 23a, a second coupling side portion 22b, 23b, and a third portion that are provided to be folded. The connecting side portions 22c and 23c are expanded and deformed so as to expand. More specifically, the first connecting side portions 22a, 23a and the second connecting side portions 22b, 23b are widened while tilting and displacing so that the first connecting side portions 22a, 23a open sideways. In this way, the second connecting side portions 22b and 23b are tilted and displaced toward the outer peripheral side of the door frame 2. As a result, the first connecting side portions 22a and 23a, the second connecting side portions 22b and 23b, and the third connecting side portions 22c and 23c are bent at each intermediate position, or the base portion 17 is displaced left and right. Without this, the base portions 17 can be displaced relatively smoothly upward so that the connecting portions 22 and 23 are relatively smoothly extended upward and the side walls 18 and 19 are not affected.

また、第２連結辺部２２ｂと第３連結辺部２２ｃとの連結部位や第３連結辺部２２ｃについては、比較的厚肉であるため、第１連結辺部２２ａや第２連結辺部２２ｂの第１連結辺部２２ａとの連結部位に比べると変形し難いが、少なくとも基底部１７が比較的大きく上方に変位させられ、第１連結辺部２２ａや第２連結辺部２２ｂの第１連結辺部２２ａとの連結部位における緊張がある程度高まった場合等には、追従的に変形する。これにより、第１連結辺部２２ａや第２連結辺部２２ｂの第１連結辺部２２ａとの連結部位へ過大な負担がかかることを防止することができ、第１連結辺部２２ａや第２連結辺部２２ｂの第１連結辺部２２ａとの連結部位が損傷する等のおそれを防止することができる。   Moreover, since the connection part of the 2nd connection side part 22b and the 3rd connection side part 22c and the 3rd connection side part 22c are comparatively thick, it is the 1st connection side part 22a and the 2nd connection side part 22b. Although it is hard to deform | transform compared with the connection site | part with the 1st connection side part 22a of this, at least the base part 17 is displaced comparatively large upwards, and the 1st connection side part 22a and the 1st connection side of the 2nd connection side part 22b are carried out. When the tension at the connecting portion with the side portion 22a is increased to some extent, it deforms following up. Thereby, it can prevent that an excessive burden is applied to the connection part with the 1st connection side part 22a of the 1st connection side part 22a or the 2nd connection side part 22b, and the 1st connection side part 22a and the 2nd It is possible to prevent a possibility that the connecting portion of the connecting side portion 22b with the first connecting side portion 22a is damaged.

尚、図２に示すように、サッシュ部ＤＳには、押出成形部５の基底部１７上面と対向する位置において、インナパネル３１が折り曲げられることで形成された取付壁部３６が設けられている。取付壁部３６のドアフレーム２外周側面には図示しないドアウエザストリップが（例えば、クリップで）取付けられている。   As shown in FIG. 2, the sash portion DS is provided with a mounting wall portion 36 formed by bending the inner panel 31 at a position facing the upper surface of the base portion 17 of the extruded portion 5. . A door weather strip (not shown) is attached to the outer peripheral side surface of the door wall 2 of the attachment wall portion 36 (for example, with a clip).

一方、取付壁部３６のドアフレーム２内周側面には、ドアガラスＧが上昇して窓部Ｗが閉鎖された際に、ドアガラスＧの上縁部で押圧される押出成形部５の基底部１７を支持して、基底部１７のそれ以上の上方への変位を規制するストッパ部材３８（図１参照）が取付けられている。すなわち、ストッパ部材３８は、取付壁部３６と押出成形部５の基底部１７との間の空間に設置されており、本実施形態では、押出成形部５の前後２箇所に対応して設けられている。   On the other hand, on the inner peripheral side surface of the door frame 2 of the mounting wall portion 36, the base of the extrusion molding portion 5 that is pressed by the upper edge portion of the door glass G when the door glass G rises and the window portion W is closed. A stopper member 38 (see FIG. 1) that supports the portion 17 and restricts further upward displacement of the base portion 17 is attached. That is, the stopper member 38 is installed in a space between the mounting wall portion 36 and the base portion 17 of the extrusion molding portion 5. In the present embodiment, the stopper member 38 is provided corresponding to two places before and after the extrusion molding portion 5. ing.

通常、ストッパ部材３８は、押出成形部５の基底部１７上面に対して近接配置されており、上昇するドアガラスＧによって押出成形部５の基底部１７が若干上方に持ち上げられると、かかる基底部１７上面がストッパ部材３８によって支持され、ドアガラスＧのそれ以上の上方への変位が規制されることとなる。しかしながら、サッシュ部ＤＳ、インナパネル３１、及び、ガラスラン４の製造誤差や取付誤差等が生じ、ストッパ部材３８が正規の位置よりも上方に位置ずれして設けられた場合には、窓部Ｗの閉時にドアガラスＧに押圧されて基底部１７が比較的大きく上方に変位してしまうことが懸念される。この点、上記のように車内側連結部２２及び車外側連結部２３を備えることによって、基底部１７の上方への変位の影響が側壁部１８、１９に及ぶことを防止することができ、たとえ基底部１７が上方に変位したとしても、意匠リップ１４、１５が側方に開くようにして変形してしまうといった事態を回避することができる。   Usually, the stopper member 38 is disposed close to the upper surface of the base portion 17 of the extruded portion 5, and when the base portion 17 of the extruded portion 5 is lifted slightly upward by the rising door glass G, the base portion is provided. The upper surface of 17 is supported by the stopper member 38, and further upward displacement of the door glass G is restricted. However, when a manufacturing error or a mounting error of the sash portion DS, the inner panel 31, and the glass run 4 occurs, the window portion W is provided when the stopper member 38 is provided with a position shifted from the normal position. When the door is closed, there is a concern that the base portion 17 is displaced relatively upward by being pressed by the door glass G. In this regard, by providing the vehicle interior coupling portion 22 and the vehicle exterior coupling portion 23 as described above, it is possible to prevent the influence of the upward displacement of the base portion 17 from reaching the side wall portions 18 and 19. Even if the base portion 17 is displaced upward, it is possible to avoid a situation in which the design lips 14 and 15 are deformed so as to open sideways.

尚、押出成形部６、７、型成形部８、９についても、基本的に押出成形部５と同様の断面形状をなし、本体部１１及びシールリップ１２、１３等を備えている。但し、ガラスラン４のうち、ベルトライン１０（図１参照）よりも上方に位置するドアサッシュＤＳに取付けられる部位（フレーム対応部）に関しては意匠リップ１４、１５が設けられているが、ベルトライン１０の下方に延設されているチャンネル部ＤＣに取付けられる部位（パネル対応部）に関しては、チャンネル部ＤＣが断面略コ字状のチャンネル部材を具備することから意匠リップ１４、１５が省略されている。また、押出成形部６、７、型成形部８、９に関しては、連結部２２、２３や内リップ２５が省略されている。   The extrusion molding parts 6 and 7 and the mold molding parts 8 and 9 also basically have the same cross-sectional shape as the extrusion molding part 5 and are provided with a main body part 11 and seal lips 12 and 13. However, in the glass run 4, design lips 14 and 15 are provided for a portion (frame corresponding portion) attached to the door sash DS positioned above the belt line 10 (see FIG. 1). For the portion (panel corresponding portion) attached to the channel portion DC extending below 10, the design lips 14 and 15 are omitted because the channel portion DC includes a channel member having a substantially U-shaped cross section. Yes. Further, with respect to the extrusion molded parts 6 and 7 and the mold molded parts 8 and 9, the connecting parts 22 and 23 and the inner lip 25 are omitted.

以上詳述したように、本実施形態によれば、ドアガラスＧで窓部Ｗを閉鎖した場合に、ガラスラン４の上辺部を構成する押出成形部５の基底部１７がドアガラスＧによって押し上げられたとしても、車内側連結部２２及び車外側連結部２３が追従的に上方に伸長するようにして変形することから、基底部１７の変位に起因する応力が車内側側壁部１８及び車外側側壁部１９に対してほとんど及ばないようにすることができる。従って、ドアガラスＧによって押し上げられた基底部１７とともに一対の側壁部１８、１９が上方に引っ張られて上方に変位してしまうことに起因して、一対の意匠リップ１４、１５が本体部１１の外方に広がるようにして変形（口開き）してしまうといった懸念を払拭することができる。結果として、窓部Ｗの閉鎖時等において、意匠リップ１４、１５がフランジ部３３、３４から離間してしまうことを防止することができ、外観品質の向上を図ることができる。   As described above in detail, according to the present embodiment, when the window portion W is closed with the door glass G, the base portion 17 of the extruded portion 5 constituting the upper side portion of the glass run 4 is pushed up by the door glass G. Even if the inner side connecting portion 22 and the outer side connecting portion 23 are deformed so as to extend upward in a follow-up manner, the stress caused by the displacement of the base portion 17 may cause stress on the inner side wall portion 18 and the outer side of the vehicle. It is possible to make it hardly reach the side wall portion 19. Therefore, the pair of side wall portions 18 and 19 are pulled upward together with the base portion 17 pushed up by the door glass G and displaced upward, so that the pair of design lips 14 and 15 are attached to the main body portion 11. It is possible to dispel the concern that it will deform outwardly (open mouth). As a result, it is possible to prevent the design lips 14 and 15 from being separated from the flange portions 33 and 34 when the window portion W is closed, and the appearance quality can be improved.

特に、本実施形態によれば、車内側及び車外側の両方に同様の連結部２２、２３が設けられているため、車内側意匠リップ１４及び車外側意匠リップ１５の両方に関して上記作用効果が奏されることとなる。さらに、例えば、車内側連結部２２又は車外側連結部２３のどちらか一方だけが設けられる場合に比べ、ドアガラスＧによって基底部１７が押圧された際に、傾倒変位した基底部１７によってドアガラスＧが車内側又は車外側に不要に変位させられてしまうといった事態を回避することができる。   In particular, according to the present embodiment, the same connecting portions 22 and 23 are provided on both the vehicle interior side and the vehicle exterior side, so that the above-described effects can be achieved with respect to both the vehicle interior design lip 14 and the vehicle exterior design lip 15. Will be. Further, for example, when only the base portion 17 is pressed by the door glass G, the door glass is tilted and displaced by the base portion 17 as compared with the case where only one of the vehicle inner side connection portion 22 and the vehicle outer side connection portion 23 is provided. It is possible to avoid a situation in which G is unnecessarily displaced inside or outside the vehicle.

また、本実施形態では、第１連結辺部２２ａ、２３ａは、側壁部１８、１９から本体部１１の外周側に延出している。このため、押出成形部５の基底部１７が上方に相対変位する際に、第１連結辺部２２ａ、２３ａを側方に開くように傾倒させつつ（チャンネル部材がないことから第１連結辺部２２ａ、２３ａが外側に開くスペースは十分にある）、連結部２２、２３を上方に伸長変形させる（第２連結辺部２２ｂ、２３ｂをドアフレーム２外周側に向けて傾倒させる）ことができる。すなわち、例えば、第１連結辺部２２ａ、２３ａが本体部１１内周側に延出している場合には、連結部２２、２３を上方に伸長変形させようとしても、連結部２２、２３の左右方向への変位を許容するような余地がないことから、第１連結辺部２２ａ、２３ａや第３連結辺部２２ｃ、２３ｃを無理やりに中間部位から屈曲変形させない限り、連結部２２、２３を上方に伸長させることができない。これでは、連結辺部２２ａ、２３ａ、２２ｃ、２３ｃへの負担が大きく、連結辺部２２ａ、２３ａ、２２ｃ、２３ｃが破れてしまうおそれがある。さらには、伸長変形したとしても、ドアガラスＧが基底部１７から離間して、ドアガラスＧからの応力が解除されたにもかかわらず、自身の弾性力では伸長変形前の元の断面形状に戻れないようになってしまうことが懸念される。この点、本実施形態のように、第１連結辺部２２ａ、２３ａを側壁部１８、１９から本体部１１外周側に延出させ、連結部２２、２３を伸長変形させる際に、連結辺部２２ａ、２３ａ、２２ｂ、２３ｂ、２２ｃ、２３ｃの中間部位を屈曲させることなく、連結部位においてスムースに展開させる構成を採用することにより、上記不具合を払拭することができる。   In the present embodiment, the first connecting side portions 22 a and 23 a extend from the side wall portions 18 and 19 to the outer peripheral side of the main body portion 11. Therefore, when the base portion 17 of the extruded portion 5 is relatively displaced upward, the first connecting side portions 22a and 23a are tilted so as to open sideways (there is no channel member, so the first connecting side portion 22a, 23a has sufficient space to open outward), and the connecting portions 22, 23 can be extended and deformed upward (the second connecting side portions 22b, 23b are tilted toward the outer peripheral side of the door frame 2). That is, for example, when the first connecting side portions 22a and 23a extend to the inner peripheral side of the main body 11, even if the connecting portions 22 and 23 are extended and deformed upward, Since there is no room to allow displacement in the direction, the connecting portions 22 and 23 are moved upward unless the first connecting side portions 22a and 23a and the third connecting side portions 22c and 23c are forcibly bent and deformed from the intermediate portion. Cannot be stretched. In this case, the burden on the connecting side portions 22a, 23a, 22c, and 23c is large, and the connecting side portions 22a, 23a, 22c, and 23c may be broken. Furthermore, even if the door glass G is separated from the base portion 17 and the stress from the door glass G is released even if it is stretched and deformed, the original cross-sectional shape before the stretch deformation is obtained by its own elastic force. There is a concern that they will not be able to return. In this regard, as in the present embodiment, when the first connecting side portions 22a and 23a are extended from the side wall portions 18 and 19 to the outer peripheral side of the main body 11 and the connecting portions 22 and 23 are extended and deformed, the connecting side portions By adopting a configuration in which the intermediate portions of 22a, 23a, 22b, 23b, 22c, and 23c are smoothly expanded at the connection portion without being bent, the above-described problems can be eliminated.

さらに、例えば、連結部２２、２３が第１連結辺部２２ａ、２３ａ、及び、第２連結辺部２２ｂ、２３ｂのみで構成される場合において、各連結辺部２２ａ、２３ａ、２２ｂ、２３ｂが短過ぎる場合、伸縮変形量が小さくなり、ドアガラスＧによって押出成形部５の基底部１７が押し上げられた場合に、連結部２２、２３の変形許容量を超えてしまい、側壁部１８、１９が上方に変位してしまったり、連結部２２、２３が損傷したりするおそれがある。その一方で、各連結辺部２２ａ、２３ａ、２２ｂ、２３ｂが長過ぎる場合、本体部１１の断面形状を維持し難くなってしまうことが懸念される。   Further, for example, when the connecting portions 22 and 23 are configured only by the first connecting side portions 22a and 23a and the second connecting side portions 22b and 23b, the connecting side portions 22a, 23a, 22b, and 23b are short. If it is too large, the amount of expansion / contraction deformation becomes small, and when the base portion 17 of the extruded portion 5 is pushed up by the door glass G, the deformation allowable amount of the connecting portions 22 and 23 is exceeded, and the side wall portions 18 and 19 are moved upward. May be displaced or the connecting portions 22 and 23 may be damaged. On the other hand, when each connection side part 22a, 23a, 22b, 23b is too long, we are anxious about it becoming difficult to maintain the cross-sectional shape of the main-body part 11. FIG.

この点、第３連結辺部２２ｃ、２３ｃをも備えることで、各連結辺部２２ａ、２３ａ、２２ｂ、２３ｂ、２２ｃ、２３ｃが長過ぎてしまうことを回避しつつ、第１連結辺部２２ａ、２３ａ、及び、第２連結辺部２２ｂ、２３ｂの損傷等を防止することができる。また、基底部１７をよりフレキシブルに変位可能にすることができる。すなわち、ドアガラスＧが基底部１７に対してイレギュラーな当たり方（例えば、搭乗者がドアガラスＧを押圧した状態でドアガラスＧが閉鎖される等）をしても十分に対処することができる。   In this regard, by providing the third connecting side portions 22c, 23c, the first connecting side portions 22a, 22a, 23a, 22b, 23b, 22c, 23c are avoided from being too long. It is possible to prevent damage to 23a and the second connecting side portions 22b and 23b. Further, the base portion 17 can be displaced more flexibly. That is, even if the door glass G is irregularly hit against the base portion 17 (for example, the door glass G is closed in a state where the passenger presses the door glass G), it can be sufficiently dealt with. it can.

また、本実施形態では、第１連結辺部２２ａ、２３ａと第２連結辺部２２ｂ、２３ｂとの連結部位における厚みは、第２連結辺部２２ｂ、２３ｂと第３連結辺部２２ｃ、２３ｃとの連結部位における厚みよりも薄くなっている。このため、第２連結辺部２２ｂ、２３ｂと第３連結辺部２２ｃ、２３ｃとの連結部位よりも、第１連結辺部２２ａ、２３ａと第２連結辺部２２ｂ、２３ｂとの連結部位をより積極的に変形させることができる。これにより、連結部２２、２３を上方に伸長変形させる際に、第１連結辺部２２ａ、２３ａをよりスムースに側方に開くようにして変形させ、第２連結辺部２２ｂ、２３ｂをドアフレーム２外周側に向けてよりスムースに傾倒変形させることができる。   Moreover, in this embodiment, the thickness in the connection site | part of 1st connection edge part 22a, 23a and 2nd connection edge part 22b, 23b is 2nd connection edge part 22b, 23b, and 3rd connection edge part 22c, 23c. It is thinner than the thickness at the connecting part. For this reason, the connection part of the first connection side part 22a, 23a and the second connection side part 22b, 23b is more than the connection part of the second connection side part 22b, 23b and the third connection side part 22c, 23c. It can be actively deformed. Accordingly, when the connecting portions 22 and 23 are extended and deformed upward, the first connecting side portions 22a and 23a are deformed so as to open more smoothly to the side, and the second connecting side portions 22b and 23b are changed to the door frame. 2 It can be more smoothly tilted and deformed toward the outer peripheral side.

加えて、第３連結辺部２２ｃ、２３ｃは第１連結辺部２２ａ、２３ａよりも厚肉に構成され、車内側連結部２２の第２連結辺部２２ｂと第３連結辺部２２ｃとの連結部位は、押出成形部５の基底部１７がドアガラスＧによって押圧されていない状態では、ドアガラスＧの昇降方向に対して交差する方向において車内側側壁部１８と略当接している。このため、ドアガラスＧの昇降方向に対して交差する方向（左右方向）における基底部１７の位置ずれを抑制することができる。その一方で、車内側側壁部１８の基端部側が本体部１１内周側に傾倒することを抑制することができる。   In addition, the third connecting side portions 22c and 23c are configured to be thicker than the first connecting side portions 22a and 23a, and the second connecting side portion 22b and the third connecting side portion 22c of the vehicle interior side connecting portion 22 are connected. In a state where the base portion 17 of the extrusion molding portion 5 is not pressed by the door glass G, the portion substantially abuts on the vehicle interior side wall portion 18 in a direction intersecting with the raising / lowering direction of the door glass G. For this reason, the position shift of the base part 17 in the direction (left-right direction) crossing with the raising / lowering direction of the door glass G can be suppressed. On the other hand, it can suppress that the base end part side of the vehicle interior side wall part 18 tilts to the main body part 11 inner peripheral side.

また、第１連結辺部２２ａ、２３ａは対応する側壁部１８、１９よりも薄肉に構成されるとともに、側壁部１８、１９のドアフレーム２外周側端面のうち左右方向（ドア１の厚み方向）における本体部１１外周側部位から延出している。さらに、側壁部１８、１９のドアフレーム２外周側端面はドアガラスＧの昇降方向に対して交差する方向に傾斜して延び、押出成形部５の基底部１７がドアガラスＧによって押圧されていない状態で、車内側側壁部１８の端面と、車内側連結部２２の第２連結辺部２２ｂと第３連結辺部２２ｃとの連結部位とが、ドアガラスＧ昇降方向に対して交差する方向において略当接している。並びに、車外側の部位に関しても、車外側側壁部１９の端面と、車外側連結部２３の第２連結辺部２３ｂと第３連結辺部２３ｃとの連結部位とが、ドアガラスＧ昇降方向に対して交差する方向において対向している。このため、連結部２２、２３を包含する本体部１１をよりコンパクトにまとめることができる。   In addition, the first connecting side portions 22a and 23a are configured to be thinner than the corresponding side wall portions 18 and 19, and the left and right directions (the thickness direction of the door 1) of the end surfaces of the side walls 18 and 19 on the outer periphery side of the door frame 2. The main body 11 extends from the outer peripheral side portion. Furthermore, the end surfaces of the side walls 18 and 19 on the outer periphery side of the door frame 2 extend so as to incline in the direction intersecting the ascending / descending direction of the door glass G, and the base portion 17 of the extruded portion 5 is not pressed by the door glass G. In a state where the end surface of the vehicle inner side wall portion 18 and the connection portion of the second connection side portion 22b and the third connection side portion 22c of the vehicle inner side connection portion 22 intersect the door glass G ascending / descending direction. It is almost in contact. In addition, with respect to the vehicle outer side portion, the end surface of the vehicle outer side wall portion 19 and the connection portion between the second connection side portion 23b and the third connection side portion 23c of the vehicle outer side connection portion 23 are in the door glass G ascending / descending direction. Opposite directions are crossed. For this reason, the main-body part 11 containing the connection parts 22 and 23 can be put together more compactly.

また、押出成形部５の基底部１７がドアガラスＧによって押圧されていない状態において、基底部１７の上面と、車内側連結部２２の第１連結辺部２２ａと第２連結辺部２２ｂとの連結部位と、車外側連結部２３の第１連結辺部２３ａと第２連結辺部２３ｂとの連結部位とが、仮想の同一直線Ｘ上にほぼ位置するように構成されている。このため、例えば、左右の連結部２２、２３の第１連結辺部２２ａ、２３ａと第２連結辺部２２ｂ、２３ｂとの連結部位が、基底部１７よりも大幅に本体部１１外周側に突出位置している場合に比べ、本体部１１の断面形状を維持し易くすることができる。さらに、第１連結辺部２２ａ、２３ａ及び第２連結辺部２２ｂ、２３ｂがガラスラン４とは別の部材（例えば、ストッパ部材３８）に当接してしまって、連結部２２、２３の変形動作等に支障を来してしまうといった事態を回避することができる。また、例えば、基底部１７が、左右の連結部２２、２３の第１連結辺部２２ａ、２３ａと第２連結辺部２２ｂ、２３ｂとの連結部位よりも大幅に本体部１１外周側に突出位置している場合に比べ、基底部１７が側壁部１８、１９から上方に離間し過ぎてしまうといった事態を回避しつつ、連結部２２、２３の各連結辺部２２ａ、２３ａ、２２ｂ、２３ｂ、２２ｃ、２３ｃの長さを十分に確保することができる。   Further, in a state where the base portion 17 of the extrusion molding portion 5 is not pressed by the door glass G, the upper surface of the base portion 17 and the first connection side portion 22a and the second connection side portion 22b of the vehicle interior side connection portion 22 The connection part and the connection part of the first connection side part 23a and the second connection side part 23b of the vehicle outer side connection part 23 are configured to be substantially located on the virtual same straight line X. For this reason, for example, the connection portion between the first connection side portions 22 a and 23 a and the second connection side portions 22 b and 23 b of the left and right connection portions 22 and 23 protrudes to the outer peripheral side of the main body portion 11 more significantly than the base portion 17. Compared with the case where it is located, the cross-sectional shape of the main-body part 11 can be maintained easily. Further, the first connecting side portions 22a and 23a and the second connecting side portions 22b and 23b come into contact with a member (for example, the stopper member 38) different from the glass run 4, and the deformation operation of the connecting portions 22 and 23 is performed. It is possible to avoid such a situation that the trouble is caused. Further, for example, the base portion 17 protrudes to the outer peripheral side of the main body 11 significantly more than the connection portion between the first connection side portions 22a and 23a of the left and right connection portions 22 and 23 and the second connection side portions 22b and 23b. Compared to the case where the base portion 17 is excessively separated from the side wall portions 18 and 19, the connection side portions 22 a, 23 a, 22 b, 23 b, and 22 c of the connection portions 22 and 23 are avoided. , 23c can be sufficiently secured.
