The door-side seal portion 11 protrudes in a trapezoidal cross section on the inner side of the vehicle and forms a door-side seal surface 12 that is substantially parallel to the longitudinal direction of the vehicle body. The door-side seal portion 11 is formed by the inner body 8. Are provided continuously over the lower side and front and rear sides of the sash inner 6 and the upper side and front and rear sides of the sash inner 6.

図５に示すように、前記ウェザーストリップ９は、その基部が車体側シール部１３にクリップ等により取り付けられる。ここで、車体側シール部１３とは、車体における側部開口の周囲に連続的に設けられるもので、この車体側シール部１３が、リアドア３閉時においてドア側シール面１２と所定の間隙を有して対向する車体側シール面１４を形成している。 As shown in FIG. 5, the weather strip 9 has a base portion attached to the vehicle body side seal portion 13 with a clip or the like. Here, the vehicle body side seal portion 13 is provided continuously around the side opening of the vehicle body, and this vehicle body side seal portion 13 has a predetermined gap from the door side seal surface 12 when the rear door 3 is closed. The vehicle body side sealing surface 14 which has and opposes is formed.

リアドア３閉時には、ウェザーストリップ９の基部が車体側シール面１４に密接（当接）すると共に、ウェザーストリップ９の中空シール部がドア側シール部１１に密接（当接）することで、該ウェザーストリップ９を隔壁として車室内側空間部ＩＮと車室外側空間部ＯＵＴとが区画される。なお、フロントドア２においても同様に、車体開口を取り囲むように配されたウェザーストリップ９’に対応して、ドアインナ４’にはドア側シール部１１’が、車体側には車体側シール部１２’がそれぞれ設けられている。 When the rear door 3 is closed, the base portion of the weather strip 9 is in close contact (contact) with the vehicle body side seal surface 14, and the hollow seal portion of the weather strip 9 is in close contact (contact) with the door side seal portion 11. The interior space portion IN and the exterior space portion OUT are partitioned by using the strip 9 as a partition wall. Similarly, in the front door 2, corresponding to the weather strip 9 ′ arranged so as to surround the vehicle body opening, the door side seal portion 11 ′ is provided on the door inner 4 ′, and the vehicle body side seal portion 12 is provided on the vehicle body side. 'Is provided for each.

図３，４は、概ね上下方向に沿って延在するドア側シール面１２をサッシュインナ６とインナ本体８との継ぎ目部１５が横断している部位の拡大図である。ここで、図６を参照して説明すると、前記継ぎ目部１５とは、サッシュインナ６の前側下端部及び後側下端部において、これに車内側から重合するインナ本体８の上縁に沿う部位である。 3 and 4 are enlarged views of a portion where the joint portion 15 of the sash inner 6 and the inner body 8 crosses the door-side seal surface 12 extending substantially along the vertical direction. Here, with reference to FIG. 6, the joint portion 15 is a portion along the upper edge of the inner main body 8 that is superposed on the front lower end portion and the rear lower end portion of the sash inner 6 from the vehicle interior side. is there.

図６に示すように、サッシュインナ６におけるインナ本体８と重合する部分は、段差部１６を介して車外側（概ね車体右側）に向かってインナ本体８の板圧分だけ変位してなるジョッグル部１７とされ、これにより、ドア側シール面１２がサッシュインナ６側の部位とインナ本体８側の部位とで面一になるように設定される。 As shown in FIG. 6, the portion of the sash inner 6 that overlaps with the inner body 8 is displaced by a plate pressure of the inner body 8 toward the vehicle outer side (generally the right side of the vehicle body) via the stepped portion 16. Accordingly, the door-side seal surface 12 is set to be flush with the portion on the sash inner 6 side and the portion on the inner body 8 side.

このとき、ドア側シール面１２には、インナ本体８の上縁とジョッグル部１７の段差部１６との間に形成される溝部１８が残存することとなる。ここで、サッシュインナ６及びインナ本体８には、溝部１８近傍の部分を若干車外側に変位させる段差形状が適宜形成されており、結果的にドア側シール面１２には、前記溝部１８に対して幅広の幅広溝部１９が形成されている。 At this time, the groove 18 formed between the upper edge of the inner body 8 and the stepped portion 16 of the joggle portion 17 remains on the door-side seal surface 12. Here, the sash inner 6 and the inner body 8 are appropriately formed with a step shape that slightly displaces a portion in the vicinity of the groove portion 18 toward the outside of the vehicle. As a result, the door-side seal surface 12 has a shape with respect to the groove portion 18. A wide wide groove portion 19 is formed.

上記幅広溝部１９は、溝部１８に例えばロウ付けによるビード部２１を形成するためのガイド溝として機能するもので、このようにして溝部１８にビード部２１を設けることで、サッシュインナ６とインナ本体８との接合強度が高まると共に溝部１８が封止され、かつビード部２１の品質が向上すると共にそのドア側シール面１２からの突出量が抑えられるようになっている。 The wide groove portion 19 functions as a guide groove for forming a bead portion 21 by brazing, for example, in the groove portion 18. By providing the bead portion 21 in the groove portion 18 in this manner, the sash inner 6 and the inner body are formed. 8, the groove 18 is sealed, the quality of the bead 21 is improved, and the amount of protrusion from the door-side seal surface 12 is suppressed.

ここで、図３，４において、ドア側シール面１２における寸法Ｈで示す部分は、リアドア３閉時にウェザーストリップ９が実際に当接する部分（以下、シール当接部２２という）を示す。また、以下の説明において、サッシュインナ６の前側下端部におけるドア側シール部を１１ｆ、ドア側シール面を１２ｆ、継ぎ目部を１５ｆ、シール当接部を２２ｆということがあり（図３参照）、サッシュインナ６の後側下端部におけるドア側シール部を１１ｒ、ドア側シール部を１２ｒ、継ぎ目部を１５ｒ、シール当接部を２２ｒということがある（図４参照）。 3 and 4, the portion indicated by the dimension H on the door-side seal surface 12 indicates a portion where the weather strip 9 actually contacts when the rear door 3 is closed (hereinafter referred to as a seal contact portion 22). In the following description, the door-side seal portion at the front lower end of the sash inner 6 may be referred to as 11f, the door-side seal surface as 12f, the joint portion as 15f, and the seal contact portion as 22f (see FIG. 3). The door-side seal portion at the rear lower end of the sash inner 6 may be referred to as 11r, the door-side seal portion as 12r, the joint portion as 15r, and the seal contact portion as 22r (see FIG. 4).

図３に示すように、サッシュインナ６の前側下端部における継ぎ目部１５ｆは、当該部位におけるドア側シール面１２ｆの前方（車室外側）では概ね水平に設けられる前側水平部２３ｆとされ、該前側水平部２３ｆがドア側シール面１２ｆの前縁に沿う前側パネル折り曲げ部２４ｆを回り込んでシール当接部２２ｆの前縁に至る。この前側水平部２３ｆが、シール当接部２２ｆにおいて後方（車室内側）に位置するほど上方に位置するように傾斜する当該継ぎ目部１５ｆの傾斜部２５ｆに連なる。 As shown in FIG. 3, the joint 15 f at the front lower end of the sash inner 6 is a front horizontal portion 23 f provided substantially horizontally in front of the door-side sealing surface 12 f (outside of the passenger compartment) at the portion, The horizontal portion 23f wraps around the front panel bent portion 24f along the front edge of the door-side seal surface 12f and reaches the front edge of the seal contact portion 22f. The front horizontal portion 23f is connected to the inclined portion 25f of the seam portion 15f that is inclined so as to be positioned higher as it is located rearward (inside the vehicle compartment) in the seal contact portion 22f.

前記傾斜部２５ｆは、シール当接部２２ｆの後縁に至った後に、その後方に位置する当該継ぎ目部１５ｆの後側水平部２６ｆに連なる。この後側水平部２６ｆは、ドア側シール面１２ｆの後縁に沿う後側パネル折り曲げ部２７ｆを回り込んでドア側シール面１２ｆの後方に至る。すなわち、ドア側シール面１２ｆの前後では概ね水平に設けられる継ぎ目部１５ｆが、ドア側シール面１２ｆを横断する際に、該ドア側シール面１２ｆ上において、その車内側端部（後側水平部２６ｆ）が車外側端部（前側水平部２３ｆ）に対して上方に位置するように変化して設けられる。 The inclined portion 25f reaches the rear edge of the seal contact portion 22f and then continues to the rear horizontal portion 26f of the seam portion 15f located behind the inclined portion 25f. The rear horizontal portion 26f wraps around the rear panel bent portion 27f along the rear edge of the door side seal surface 12f and reaches the rear of the door side seal surface 12f. That is, when the joint portion 15f provided substantially horizontally before and after the door-side seal surface 12f crosses the door-side seal surface 12f, the vehicle inner end portion (rear-side horizontal portion) is formed on the door-side seal surface 12f. 26f) is provided so as to be positioned above the vehicle outer end (front horizontal portion 23f).

また、図４に示すように、サッシュインナ６の後側下端部における継ぎ目部１５ｒは、当該部位におけるドア側シール面１２ｒの前方（車室内側）では概ね水平に設けられる前側水平部２３ｒとされ、該前側水平部２３ｒがドア側シール面１２ｒの前縁に沿う前側パネル折り曲げ部２４ｒを回り込んでシール当接部２２ｒの前縁に至る。この前側水平部２３ｒが、シール当接部２２ｒにおいて後方（車室外側）に位置するほど下方に位置するように傾斜する当該継ぎ目部１５ｒの傾斜部２５ｒに連なる。 Further, as shown in FIG. 4, the joint 15r at the rear lower end portion of the sash inner 6 is a front horizontal portion 23r provided substantially horizontally in front of the door-side seal surface 12r at the portion (vehicle interior side). The front horizontal portion 23r wraps around the front panel bent portion 24r along the front edge of the door-side seal surface 12r and reaches the front edge of the seal contact portion 22r. The front horizontal portion 23r is continuous with the inclined portion 25r of the joint portion 15r that is inclined so as to be positioned lower as it is located rearward (outside of the passenger compartment) in the seal contact portion 22r.

前記傾斜部２５ｒは、シール当接部２２ｒの後縁に至った後に、その後方に位置する当該継ぎ目部１５ｒの後側水平部２６ｒに連なる。この後側水平部２６ｒは、ドア側シール面１２ｒの後縁に沿う後側パネル折り曲げ部２７ｒを回り込んでドア側シール面１２ｒの後方に至る。すなわち、前記継ぎ目部１５ｆと同様、ドア側シール面１２ｒの前後では概ね水平に設けられる継ぎ目部１５ｒが、ドア側シール面１２ｒを横断する際に、該ドア側シール面１２ｒ上において、その車内側端部（前側水平部２３ｒ）が車外側端部（後側水平部２６ｒ）に対して上方に位置するように変化して設けられる。なお、当該継ぎ目部１５ｒは、その後半部分においては後方に位置するほど上方に位置するように傾斜して設けられる。 The inclined portion 25r reaches the rear edge of the seal contact portion 22r, and then continues to the rear horizontal portion 26r of the seam portion 15r located behind the inclined portion 25r. The rear horizontal portion 26r wraps around the rear panel bent portion 27r along the rear edge of the door side seal surface 12r and reaches the rear side of the door side seal surface 12r. That is, like the seam portion 15f, when the seam portion 15r provided substantially horizontally before and after the door-side seal surface 12r crosses the door-side seal surface 12r, The end portion (front horizontal portion 23r) is provided so as to be located above the vehicle outer end portion (rear side horizontal portion 26r). In addition, the seam portion 15r is provided so as to be inclined so as to be positioned higher in the rear half of the seam portion 15r.

以上説明したように、上記実施例におけるシール部構造は、ドアインナ４を構成するサッシュインナ６及びインナ本体８の継ぎ目部１５がドア側シール面１２を横断する場合に適用されるものであって、前記継ぎ目部１５におけるドア側シール面１２上に位置する部分が、その車室内側端部が車室外側端部よりも上方に位置するように変化するものである。 As described above, the seal portion structure in the above embodiment is applied when the sash inner 6 constituting the door inner 4 and the joint portion 15 of the inner body 8 cross the door-side seal surface 12, The portion of the joint portion 15 located on the door-side seal surface 12 changes so that the vehicle interior side end portion is located above the vehicle interior outer end portion.

この構成によれば、車室外側から継ぎ目部１５内に水が入り込んでも、該継ぎ目部１５のドア側シール面１２上に位置する変化部分である傾斜部２５ｆ，２５ｒがトラップとなり、継ぎ目部１５を伝って車室内側に水が浸入することを防止できる。すなわち、ドア側シール面１２上において継ぎ目部１５を変化させるように設定することのみで、別途シール対策を施すことなく車室外側から車室内側に水が浸入することを防止できるという効果がある。 According to this configuration, even if water enters the seam portion 15 from the outside of the passenger compartment, the inclined portions 25f and 25r which are changing portions located on the door-side seal surface 12 of the seam portion 15 serve as traps, and the seam portion 15 It is possible to prevent water from entering the interior of the vehicle through the road. In other words, only by setting the seam portion 15 to be changed on the door-side seal surface 12, there is an effect that water can be prevented from entering the vehicle interior side from the outside of the vehicle interior without taking a separate sealing measure. .

また、上記シール部構造においては、前記継ぎ目部１５に、その延在方向に沿ってビード部２１が形成されている。すなわち、溶接や接着等によるビード部２１が継ぎ目部１５に沿ってドア側シール面１２を横断するように設けられることで、サッシュインナ６とインナ本体８との接合強度を高めると共に、該ビード部２１を伝って車室外側から車室内側に水が浸入することを防止できるという効果がある。 Moreover, in the said seal part structure, the bead part 21 is formed in the said joint part 15 along the extension direction. That is, by providing the bead portion 21 by welding, adhesion or the like so as to cross the door-side seal surface 12 along the joint portion 15, the bonding strength between the sash inner 6 and the inner body 8 is increased, and the bead portion Thus, there is an effect that water can be prevented from entering the vehicle interior side from the vehicle interior outside through the vehicle interior 21.

さらに、上記シール部構造においては、前記継ぎ目部１５が、前記ドア側シール面１２における実際にウェザーストリップ９が当接するシール当接部２２のみにおいて変化することで、リアドア３閉時、すなわちウェザーストリップ９がドア側シール面１２に当接してシールがなされているときには、継ぎ目部１５の変化部分である傾斜部２５ｆ，２５ｒがウェザーストリップ９により隠されることで、該傾斜部２５ｆ，２５ｒが目立たなくなり、結果的に継ぎ目部１５周辺の見栄えを向上させるという効果がある。 Further, in the seal portion structure, the seam portion 15 changes only in the seal contact portion 22 where the weather strip 9 actually contacts the door-side seal surface 12, so that the weather strip is closed. When 9 is in contact with the door-side seal surface 12 and sealing is performed, the inclined portions 25f and 25r, which are changed portions of the joint portion 15, are hidden by the weather strip 9, so that the inclined portions 25f and 25r become inconspicuous. As a result, there is an effect that the appearance around the joint portion 15 is improved.

なお、この発明は上記実施例に限られるものではなく、例えば図７に示すように、継ぎ目部１５ｆにおけるドア側シール面１２ｆ上のさらにシール当接部２２ｆ上に位置する部位において、前記傾斜部２５ｆに代わり、ドア側シール面１２ｆと共に概ね上下方向に沿って延在する上下方向延在部１２５ｆとしてもよい。これは、継ぎ目部１５ｒにおいても適用可能である。 Note that the present invention is not limited to the above-described embodiment. For example, as shown in FIG. 7, the inclined portion is formed at a portion located on the seal contact portion 22f on the door-side seal surface 12f in the joint portion 15f. Instead of 25f, it is good also as the up-down direction extension part 125f extended along the up-down direction with the door side sealing surface 12f. This can also be applied to the joint portion 15r.

また、図８に示すように、継ぎ目部１５ｆのドア側シール面１２ｆ上に位置する部分が、該ドア側シール面１２ｆの前側パネル折り曲げ部２４ｆから後側パネル折り曲げ部２７ｆに渡って傾斜する傾斜部２２５ｆとして設けられる構成であってもよい。
この構成によれば、継ぎ目部１５ｆにおける略水平に設けられる前側水平部２３ｆ及び後側水平部２６ｆと、該継ぎ目部１５ｆにおける傾斜して設けられる傾斜部２２５ｆとが、各パネル折り曲げ部２４ｆ，２７ｆにおいて連なることで、継ぎ目部１５ｆがその変化部分である傾斜部２２５ｆも含めて自然に連続しているような見え方となるため、リアドア３閉時のみならず、リアドア３開時においても、継ぎ目部１５ｆ周辺の見栄えを向上できるという効果がある。なお、上記構成は継ぎ目部１５ｒにおいても適用可能である。 Further, as shown in FIG. 8, the portion of the joint portion 15f located on the door-side seal surface 12f is inclined so as to incline from the front panel bent portion 24f to the rear panel bent portion 27f of the door-side seal surface 12f. The structure provided as the part 225f may be sufficient.
According to this configuration, the front horizontal portion 23f and the rear horizontal portion 26f provided substantially horizontally in the joint portion 15f, and the inclined portion 225f provided in an inclined manner in the joint portion 15f are each panel bent portions 24f and 27f. As a result, the joint portion 15f appears to be naturally continuous including the inclined portion 225f that is the changed portion. Therefore, the joint portion 15f is not only when the rear door 3 is closed but also when the rear door 3 is opened. There is an effect that the appearance around the portion 15f can be improved. Note that the above configuration can also be applied to the joint portion 15r.

さらに、三つ以上のパネル部材の継ぎ目部がドア側シール面１２を横断するような構成であってもよい。また、継ぎ目部１５に設けるビード部２１は、ロウ付け（接着）ビードではなく溶接ビードであってもよい。さらにまた、車体側シール面１４にも適用可能である。
そして、上記実施例における構成は一例であり、例えばフロントドア２やテールゲート等にも適用可能であることはもちろん、発明の要旨を逸脱しない範囲で種々の変更が可能であることはいうまでもない。 Furthermore, the structure which the seam part of three or more panel members crosses the door side sealing surface 12 may be sufficient. Further, the bead portion 21 provided in the joint portion 15 may be a weld bead instead of a brazing (adhesion) bead. Furthermore, the present invention can also be applied to the vehicle body side seal surface 14.
The configuration in the above embodiment is merely an example, and it can be applied to, for example, the front door 2 and the tailgate, and various changes can be made without departing from the scope of the invention. Absent.
