Description

本発明は、車体の後部側面に設置され、スライドドア開閉時にその上下中間部を案内せしめる車両のスライドドアのセンタレール構造に関する。   The present invention relates to a center rail structure for a slide door of a vehicle that is installed on a rear side surface of a vehicle body and guides the upper and lower intermediate portions when the slide door is opened and closed.

図４に示すように、ワゴン車等の車体側面のドア開口Ｋを開閉するスライドドアＤは、ドア前部の上端および下端にそれぞれ設けられたアッパおよびロアローラーＲ１，Ｒ２がドア開口Ｋの上縁および下縁に沿って設けられたアッパおよびロアレールＧ１，Ｇ２に転動自在に支持され、ドア後部の上下中間にアーム部材を介して設けられたセンタローラーＲ３がドア開口Ｋ後方のクォータパネル１に沿って設けられたセンタレールＧ３に転動自在に支持され、車両前後の開閉方向に移動案内される(例えば、特許文献１参照)。   As shown in FIG. 4, the slide door D that opens and closes the door opening K on the side of the vehicle body such as a wagon car has upper and lower rollers R <b> 1 and R <b> 2 provided at the upper and lower ends of the front part of the door, respectively. A quarter roller 1 located behind the door opening K is provided with a center roller R3 that is supported by the upper and lower rails G1 and G2 provided along the edge and the lower edge so as to be freely rollable and provided via an arm member in the middle of the rear part of the door. Is supported by the center rail G3 provided along the road and is guided to move in the opening and closing direction of the vehicle front and rear (see, for example, Patent Document 1).

図５に示すように、センタローラーＲ３は一般に、スライドドアＤ後部の上下中間位置から車内方向に延出するアーム部材６０の先端に設けた縦軸６１に回転自在に支持された水平ローラー６ａと垂直ローラー６ｂからなる。
一方、センタレールＧ３は逆Ｕ字状で水平ローラー６ａを案内するレール上部３１と、垂直ローラー６ｂを支持する平坦なレール底壁部３３と、これらを車内側でつなぐ縦壁部３２とで全体が車外側に開口する断面ほぼ角形Ｃ字状をなす。
ドア開口Ｋの後方のクォータパネル１には上半部に形成されたクォータウィンドウ開口１０（図４）の下縁に沿ってほぼ水平方向に延び、車外側に向けて開口する断面ほぼコ字状の凹溝２が形成されている。 As shown in FIG. 5, the center roller R3 generally includes a horizontal roller 6a rotatably supported by a vertical axis 61 provided at the tip of an arm member 60 extending in the vehicle interior direction from the upper and lower intermediate positions of the rear portion of the slide door D. It consists of a vertical roller 6b.
On the other hand, the center rail G3 has an inverted U-shape and is composed of a rail upper portion 31 that guides the horizontal roller 6a, a flat rail bottom wall portion 33 that supports the vertical roller 6b, and a vertical wall portion 32 that connects these inside the vehicle. Has a substantially square C-shaped cross section that opens to the outside of the vehicle.
The quarter panel 1 behind the door opening K has a substantially U-shaped cross section extending substantially horizontally along the lower edge of the quarter window opening 10 (FIG. 4) formed in the upper half and opening toward the outside of the vehicle. The concave groove 2 is formed.

センタレールＧ３は凹溝２内に収納され、縦壁部３２を上記凹溝２の奥面部２２に重ね合わせて、上下中間位置をボルト締めして固定されている。図５の３６はセンタレールＧ３の後端部において、その外周面に重ねて合わせた補強部材で、センタレールＧ３と一体に凹溝２に締結されている。なお、凹溝２の上下幅は、凹溝２のプレス成形性を考慮して広くしてあり、凹溝２の上面部２１とレール上面との間には隙間がある。   The center rail G3 is housed in the concave groove 2, and the vertical wall portion 32 is overlapped with the back surface portion 22 of the concave groove 2, and is fixed by bolting the upper and lower intermediate positions. Reference numeral 36 in FIG. 5 denotes a reinforcing member overlapped with the outer peripheral surface of the rear end portion of the center rail G3, and is fastened to the concave groove 2 integrally with the center rail G3. In addition, the vertical width of the groove 2 is increased in consideration of the press formability of the groove 2, and there is a gap between the upper surface portion 21 of the groove 2 and the rail upper surface.

またセンタレールＧ３は、クォータウィンドウ開口１０を塞ぐクォータウィンドウガラス７のガラス下端部により覆い隠されている。ガラス下端部の下縁７１と凹溝２の開口下縁との間には間隙が設けられ、該間隙に先端にローラー６ａ，６ｂを保持するアーム部材６０が挿通されている。
特開平１０−３１５７７６号公報 The center rail G3 is covered with a lower end portion of the quarter window glass 7 that closes the quarter window opening 10.

Japanese Patent Laid-Open No. 10-315776

図６に示すようにスライドドアＤは開放操作時、全開位置で、アッパおよびロアローラー部Ｒ１，Ｒ２がそれぞれ、アッパおよびロアレールＧ１，Ｇ２の後端に設置されたストッパＳに当接してこれ以上の開き移動が規制される。
ところで、スライドドアＤの開閉が繰り返されると、センタレールＧ３が傾く傾向があり、この傾向が進行するとローラーＲ３がセンタレールＧ３から外れるおそれが生じる。
またスライドドアＤが開ききる際にセンタローラーＲ３を支持するアーム部材６０が瞬間的に上方へ動きアーム部材６０とクォータウィンドウガラス７の下縁７１との間の設定間隔が小さいと、アーム部材６０がクォータウィンドウガラス７と干渉し、これを破損させるおそれがある。 As shown in FIG. 6, when the sliding door D is opened, the upper and lower roller portions R1 and R2 are in contact with the stopper S installed at the rear ends of the upper and lower rails G1 and G2, respectively. The movement of opening is restricted.
By the way, when the opening and closing of the slide door D is repeated, the center rail G3 tends to tilt, and when this tendency proceeds, the roller R3 may come off from the center rail G3.
If the arm member 60 that supports the center roller R3 momentarily moves upward when the slide door D is fully opened, and the setting interval between the arm member 60 and the lower edge 71 of the quarter window glass 7 is small, the arm member 60 May interfere with the quarter window glass 7 and break it.

発明者らはかかる不都合が発生する原因について研究実験を重ねた結果、次のような原因によるものと認めた。
図６に示すように、スライドドアＤは強開操作されると、アッパローラーＲ１およびロアローラーＲ２がストッパＳに突き当たって急激に停止させられ、スライドドアＤはその前端のアッパローラーＲ１およびロアローラーＲ２を中心としてドアＤの後部を車内側へ回転させる回転モーメント(黒矢印Ｍ)が作用する。
このため図５に示すように、センタレールＧ３の後部では水平ローラー６ａがレール上部３１を車内方向へ押し込み(黒矢印Ｘ)、これによりセンタレールＧ３は凹溝２の奥面部２２の上部を撓ませつつ凹溝２との結合部Ｆを中心として車外側が持上げられるようにして全体が車内側へ回動して傾倒する(白矢印Ｙ)。そして強開操作が繰り返されるとセンタレールＧ３の後端部は次第に傾斜姿勢となる。
このときセンタローラーＲ３はセンタレールＧ３とともに車内側へ傾斜し、先端が傾斜した縦軸６１を支持するアーム部材６０は上方へ移動して(白矢印Ｚ)クォータウィンドウガラス７の下縁７１に接近する。
センタローラーＲ３は凹溝２の奥面部２２に押し付けられた反動で元に戻ろうとし、このとき傾倒したセンタレールＧ３の車外側のローラー案内部３４は上方に持ち上げられているから水平ローラー６ａの当接位置は相対的に下方へ移り水平ローラー６ａの掛り代は小さくなる。ドアの強開操作が繰り返されると、次第に掛り代が小さくなっていき、水平ローラー６ａがセンタレールＧ３からはずれるおそれが生じる。 As a result of repeated research and experiments on the cause of such inconvenience, the inventors have found that the cause is as follows.
As shown in FIG. 6, when the sliding door D is forcibly opened, the upper roller R1 and the lower roller R2 abut against the stopper S and are suddenly stopped, and the sliding door D has the upper roller R1 and the lower roller at the front end thereof. A rotational moment (black arrow M) that rotates the rear part of the door D inward of the vehicle around R2 acts.
Therefore, as shown in FIG. 5, at the rear of the center rail G3, the horizontal roller 6a pushes the rail upper portion 31 toward the vehicle interior (black arrow X), so that the center rail G3 bends the upper portion of the back surface portion 22 of the groove 2. However, as a result, the entire vehicle is turned to the vehicle inner side so that the vehicle outer side is lifted around the joint F with the concave groove 2 (white arrow Y). When the strong opening operation is repeated, the rear end portion of the center rail G3 is gradually inclined.
At this time, the center roller R3 and the center rail G3 are inclined toward the inside of the vehicle, and the arm member 60 that supports the vertical axis 61 whose tip is inclined moves upward (white arrow Z) and approaches the lower edge 71 of the quarter window glass 7. To do.
The center roller R3 tries to return to the original by the reaction that is pressed against the inner surface 22 of the concave groove 2, and the roller guide 34 on the outside of the center rail G3 tilted at this time is lifted upward, so that the horizontal roller 6a The abutting position moves relatively downward, and the hanging amount of the horizontal roller 6a becomes small. When the door opening operation is repeated, the hanging margin gradually decreases, and the horizontal roller 6a may be separated from the center rail G3.

本発明は上記の知見に基き、スライドドアの強開操作が繰り返されても、センタローラーを支持するアーム部材がクォータウィンドウガラスの下縁と干渉してこれを破損させるおそれがなく、かつセンタローラーがセンタレールから脱落するおそれがない車両のセンタレール構造を実現することを課題としてなされたものである。   The present invention is based on the above knowledge, and even when the sliding door is forcibly opened repeatedly, there is no possibility that the arm member supporting the center roller interferes with and breaks the lower edge of the quarter window glass, and the center roller. It is an object of the present invention to realize a vehicle center rail structure in which there is no risk of falling off the center rail.

本発明は、車両のドア開口の後方の車体側面に沿ってほぼ水平方向に延び、車外側へ向けて開口する断面ほぼコ字状をなす凹溝の内部に、スライドドアの後端の上下中央部に設けたローラーを転動案内せしめるセンタレールを設置した車両のセンタレール構造において、センタレールは車外側に向けて開口する断面ほぼ角形Ｃ字状をなし、車内側の縦壁部を上記凹溝の奥面部に固定せしめる。センタレールのレール後端部には、その上壁部の車外側寄りの位置に、該上壁部と間隔をおいて対向する上記凹溝の上面部との間を詰めてセンタレールの車内側の傾倒を抑制するストッパ部材を設ける（請求項１）。
スライドドアの強開によりセンタレールの後端部にこれを車内側へ倒す力が作用しても、センタレールの上端部の車外側寄りに設けて凹溝の上面部との間を詰めるストッパ部材によりセンタレールの傾倒を抑制することができる。 The present invention provides a horizontal center extending substantially along the side of the vehicle body behind the door opening of the vehicle, and having a substantially U-shaped cross-section opening toward the outside of the vehicle. In the center rail structure of a vehicle provided with a center rail that rolls and guides the rollers provided in the section, the center rail has a substantially square C-shaped cross section that opens toward the outside of the vehicle, and the vertical wall portion on the inside of the vehicle Secure to the back of the groove. At the rear end of the rail of the center rail, the space between the upper wall and the upper surface of the concave groove facing the upper wall is spaced from the upper wall of the center rail. A stopper member is provided to suppress the tilting.
Stopper member that closes the upper surface of the concave groove by providing the rear end of the center rail to the vehicle inner side due to the strong opening of the sliding door, even if the upper end of the center rail is closer to the vehicle outer side. Thus, tilting of the center rail can be suppressed.

上記ストッパ部材を硬質ゴムまたは合成樹脂のブロック体で構成する（請求項２）。
ストッパ部材を硬質ゴムまたは合成樹脂としたので車両走行時の凹溝上面部との間で振動音など異音の発生や上面部の傷付きを抑制する。 The stopper member is composed of a hard rubber or synthetic resin block.
Since the stopper member is made of hard rubber or synthetic resin, occurrence of abnormal noise such as vibration noise and scratches on the upper surface portion are suppressed between the upper surface portion of the groove and the vehicle running.

上記凹溝は、上部にクォータウィンドウ開口を設けた車体のクォータパネルに、上記クォータウィンドウ開口の下縁に沿って形成する。上記ローラーはスライドドアから車内方向に延出せしめたアーム部材の先端に支持せしめられる。上記センタレールは、クォータウィンドウ開口を塞ぐクォータウィンドウガラスのガラス下端部で覆い隠され、上記ガラス下端部の下縁と上記凹溝の開口下縁との間に、間隙が形成され、該間隙に上記アーム部材を挿通して上記ローラーが上記センタレールを転動するようになす。上記センタレールのレール後端部の上壁部に上記ストッパ部材を設ける（請求項３）。
センタレールの傾倒が抑制されることでセンタローラーの姿勢が変化せず、これによりアーム部材の上下動は抑制される。従って、アーム部材を挿通する間隙を小さくしてもアーム部材はクォータウィンドウガラスと干渉しない。 The concave groove is formed along the lower edge of the quarter window opening in a quarter panel of a vehicle body provided with a quarter window opening in the upper part. The roller is supported by the tip of an arm member that extends in the vehicle interior direction from the slide door. The center rail is covered and concealed by a glass lower end portion of the quarter window glass that closes the quarter window opening, and a gap is formed between the lower edge of the glass lower end portion and the opening lower edge of the concave groove. The roller is caused to roll on the center rail through the arm member. The stopper member is provided on the upper wall portion of the rail rear end portion of the center rail.
By suppressing the tilt of the center rail, the posture of the center roller does not change, and thereby the vertical movement of the arm member is suppressed. Therefore, even if the gap through which the arm member is inserted is reduced, the arm member does not interfere with the quarter window glass.

上記凹溝の上面部は、凹溝が車外側に向けて外開きとなる緩やかな傾斜状に形成され、上記ストッパ部材を、その上端面が上記上面部と平行面をなし、かつ僅少の間隔をおいて対向するように設置する（請求項４）。
凹溝の上壁とストッパ部材との間に僅少の隙間を設けることで、センタレールを取付けた状態で車体を電着塗装する場合、凹溝内を完全に塗装できる。またストッパ部材の上端面を凹溝の上面部と平行に形成したので、ストッパ部材のセンタレールの傾倒抑制機能を効果的に発揮させることができる。 The upper surface portion of the concave groove is formed in a gently inclined shape so that the concave groove opens outwardly toward the vehicle exterior, and the stopper member has an upper end surface that is parallel to the upper surface portion and has a slight gap. And so as to face each other (claim 4).
By providing a slight gap between the upper wall of the groove and the stopper member, the interior of the groove can be completely painted when the vehicle body is electrodeposition coated with the center rail attached. Further, since the upper end surface of the stopper member is formed in parallel with the upper surface portion of the concave groove, the function of suppressing the tilt of the center rail of the stopper member can be effectively exhibited.

上記レール後端部には、その外周面に重ね合わせてこれを補強する補強部材が設けられ、該補強部材の上壁部に上記ストッパ部材を設ける（請求項５）。   The rear end of the rail is provided with a reinforcing member that overlaps and reinforces the outer peripheral surface thereof, and the stopper member is provided on the upper wall portion of the reinforcing member.

図４に示した車両のセンタレール構造に本発明を適用した実施形態を、図１、図２に基いて説明する。図１はセンタレールの後端部の縦断面図、図２はセンタレールの後端部におけるストッパ部材の設置構造を示す。
図４および図１に示すように、センタレールＧ３はドア開口Ｋ後方の車体側面をなすクォータパネル１の上下中間位置で、クォータウィンドウ開口１０の下縁に沿って前後方向に延設してある。 An embodiment in which the present invention is applied to the center rail structure of the vehicle shown in FIG. 4 will be described with reference to FIGS. FIG. 1 is a longitudinal sectional view of a rear end portion of the center rail, and FIG. 2 shows an installation structure of a stopper member at the rear end portion of the center rail.
As shown in FIGS. 4 and 1, the center rail G <b> 3 extends in the front-rear direction along the lower edge of the quarter window opening 10 at the upper and lower intermediate positions of the quarter panel 1 that forms the side of the vehicle body behind the door opening K. .

クォータパネル１にはそのセンタレール取付位置に、上面部２１、下壁部２３およびこれらの車内側の側縁を上下につないだ奥面部２２とからなり、車外側に向けて開口する断面ほぼコ字状の凹溝２が形成してある。凹溝２は断面形状が車外側に向けて若干外開きとなるように、上面部２１を緩やかに外向き斜め上方へ延びる傾斜面とし、かつ下壁部２３を外向き斜め下方へ延びる傾斜面に形成してある。凹溝２の上下幅はセンタレールＧ３の上下幅よりも大きく設定してある。
センタレールＧ３はスライドドアＤの後部の上下中間部に設けられたセンタローラーＲ３を転動して、ドア開閉時にスライドドアＤの後部を案内する。 The quarter panel 1 includes an upper surface portion 21, a lower wall portion 23, and a rear surface portion 22 in which the side edges on the inner side of the vehicle are vertically connected at the center rail mounting position. A character-shaped concave groove 2 is formed. The concave groove 2 has an upper surface portion 21 which is inclined to extend obliquely upward and obliquely upward, and a lower wall portion 23 which extends obliquely downward and outward so that the cross-sectional shape slightly opens outward toward the vehicle exterior. Is formed. The vertical width of the concave groove 2 is set to be larger than the vertical width of the center rail G3.
The center rail G3 rolls a center roller R3 provided at the upper and lower intermediate part of the rear part of the slide door D, and guides the rear part of the slide door D when the door is opened and closed.

センタローラーＲ３は、図1に示すように、基端がスライドドアの車内面に固定されて車内側へ延出するアーム部材６０の先端に設けてある。センタローラーＲ３は、断面ほぼＺ字状に形成されて基端側よりも一段高く形成したアーム部材６０の先端部に、上方へ起立する垂直の縦軸６１に回転可能に軸支した水平ローラー６ａと、水平ローラー６ａよりも低い位置でアーム部材６０の先端部から車内側へ水平に突設した横軸６２に回転可能に軸支した垂直ローラー６ｂとからなる。   As shown in FIG. 1, the center roller R3 is provided at the distal end of an arm member 60 whose base end is fixed to the inner surface of the sliding door and extends toward the inner side of the vehicle. The center roller R3 is formed in a substantially Z-shaped cross section and is horizontally supported at a distal end of an arm member 60 which is formed one step higher than the base end side. And a vertical roller 6b rotatably supported on a horizontal shaft 62 that protrudes horizontally from the front end of the arm member 60 to the vehicle inner side at a position lower than the horizontal roller 6a.

センタレールＧ３は金属製の長尺レール材からなり、全長にわたって同一断面形状をなす。センタレールＧ３は、水平ローラー６ａを転動案内せしめる断面逆Ｕ字状のレール上部３１と、その下方で、垂直ローラー６ｂを支持して転動せしめるほぼ平坦なレール底壁部３３、およびレール上部３１およびレール底壁部３３の車内側の側縁同士を上下につなぐ縦壁部３２とを備え、断面形状を車外側に向けて開口するほぼ角形Ｃ字状に形成してある。
なお、レール底壁部３３にはローラー転動面を形成するように、縦壁部３２側からレール底壁部３３よりも車外側へ延びる断面ほぼＬ字状の被覆部材３５が設けてある。 The center rail G3 is made of a metal long rail material and has the same cross-sectional shape over the entire length. The center rail G3 includes an inverted U-shaped rail upper portion 31 for rolling and guiding the horizontal roller 6a, a substantially flat rail bottom wall portion 33 for supporting and rolling the vertical roller 6b below, and an upper portion of the rail. 31 and a vertical wall portion 32 that connects the side edges of the rail bottom wall portion 33 on the inside of the vehicle up and down, and the cross-sectional shape is formed in a substantially square C shape that opens toward the outside of the vehicle.
The rail bottom wall 33 is provided with a covering member 35 having an approximately L-shaped cross section extending from the vertical wall 32 side to the vehicle outer side so as to form a roller rolling surface.

図１、図２に示すように、センタレールＧ３の後端部には、レール上部３１、縦壁部３２およびレール底壁部３３の外周面に重ね合わせるように断面ほぼ角形Ｃ字状の補強部材３６が設けてある。補強部材３６はセンタレールＧ３の後端部の前後方向に沿う所定の長さ形成してあり、その長さは約１０cmに設定してある。   As shown in FIGS. 1 and 2, the rear end portion of the center rail G3 has a substantially square C-shaped reinforcing section so as to overlap the outer peripheral surfaces of the rail upper portion 31, the vertical wall portion 32, and the rail bottom wall portion 33. A member 36 is provided. The reinforcing member 36 has a predetermined length along the front-rear direction of the rear end portion of the center rail G3, and the length is set to about 10 cm.

補強部材３６の上壁部３７はセンタレールＧ３の上面部と重合し、ほぼ水平の平坦面に形成してある。そして上壁部３７には車外側の位置に硬質ゴムのブロック体からなるストッパ部材５が前後方向に設置してある。ストッパ部材５は下面を上壁部３７に接着してあり、ストッパ部材５の上端面５１はその車外側の側縁が車内側の側縁よりも若干高位となる緩やかな傾斜面をなす凹溝２の上面部２１にそう形状としてある。ストッパ部材５の前後幅は補強部材３６よりも短くしてある。   The upper wall portion 37 of the reinforcing member 36 overlaps with the upper surface portion of the center rail G3 and is formed on a substantially horizontal flat surface. The upper wall portion 37 is provided with a stopper member 5 made of a hard rubber block body in the front-rear direction at a position outside the vehicle. The stopper member 5 has a lower surface bonded to the upper wall portion 37, and the upper end surface 51 of the stopper member 5 is a concave groove having a gently sloping surface whose side edge on the vehicle outer side is slightly higher than the side edge on the vehicle inner side.

この場合、センタレールＧ３の後端部の上壁部３７に設置したストッパ部材５はその上端面５１を凹溝２の上面部２１の下面の車外側の位置に当接せしめて上壁部３７と上面部２１との間隙を詰めるに構成してある。
また被覆部材３５の車外側の端縁はシール材３５１を介して下壁部２３の車外側位置に重ね合わせて下壁部２３との間の間隙は塞いである。 The center rail G3 is a covering member formed by a bolt member B that penetrates the vertical wall portion 32 of the vertical wall portion 32 by overlapping the vertical wall portion 32 integrally with the vertical wall portion of the reinforcing member 36 on the back surface portion 22 of the concave groove 2. 35 and the reinforcing member 36 are integrally fastened to the vertical wall portion 22 of the groove 2.
In this case, the stopper member 5 installed on the upper wall portion 37 of the rear end portion of the center rail G3 brings the upper end surface 51 into contact with the position on the vehicle outer side of the lower surface of the upper surface portion 21 of the groove 2 so that the upper wall portion 37 is in contact. And the gap between the upper surface portion 21 and the upper surface portion 21.
In addition, the outer edge of the covering member 35 is overlapped with the position of the lower wall portion 23 via the sealing material 351 so as to close the gap between the lower wall portion 23 and the covering member 35.

なお、センタレールＧ３の後端部以外の一般部では、縦壁部を直接、凹溝の奥閉部に重ね合わせて締結してあり、レールの上壁部と凹溝の上壁部との間には間隙が空いている。   In addition, in the general part other than the rear end part of the center rail G3, the vertical wall part is directly overlapped and fastened to the back closed part of the groove, and the upper wall part of the rail and the upper wall part of the groove are There is a gap between them.

センタローラーＲ３は、水平ローラー６ａをセンタレールＧ３のレール上部３１に挿入して、ローラー面がレール上部３１の車外側および車内側のレール案内部３４に沿って転動可能に係合するとともに、垂直ローラー６ｂをレール底壁部３３を覆う被覆部材３５の上面に設置してこれに沿って転動可能に係合してある。   The center roller R3 inserts the horizontal roller 6a into the rail upper part 31 of the center rail G3, and the roller surface engages with the outer side of the rail upper part 31 and the rail guide part 34 on the inner side of the rail so that it can roll, The vertical roller 6b is installed on the upper surface of the covering member 35 that covers the rail bottom wall portion 33, and is engaged so as to be able to roll along this.

またセンタレールＧ３は、凹溝２と一体にその上方のクォータウィンドウ開口１０(図４)を塞ぐクォータウィンドウガラス７の下方へ拡張した下縁７１で覆い隠される。クォータウィンウドガラス７の下縁７１と凹溝２の開口下縁との間には上下方向に間隙が空けてあり、これにセンタローラーＲ３のアーム部材６０を挿通してある。   Further, the center rail G3 is covered with a lower edge 71 extended downward from the quarter window glass 7 that integrally closes the quarter window opening 10 (FIG. 4) with the concave groove 2. There is a vertical gap between the lower edge 71 of the quarter window glass 7 and the lower edge of the opening of the groove 2, and the arm member 60 of the center roller R <b> 3 is inserted through this gap.

スライドドアの強開操作により開ききったとき、スライドドアにその後部を車内側へ移動さる回転モーメントＭ（図６参照）が発生すると、センタレールＧ３の後端部には、センタローラーＲ３の水平ローラー６ａからレール上部３１の車内側のレール案内部３４にこれを車内側へ押す力(図１の黒矢印Ｘ)が作用して、これによりセンタレールＧ３は凹溝２との結合部Ｆを中心として車外側が持上げられるようにして車内側へ回動して傾倒しようとする。   When the sliding door is fully opened by the forcible opening operation, if a rotational moment M (see FIG. 6) that moves the rear portion of the sliding door to the inside of the vehicle is generated, the center roller R3 is placed horizontally at the rear end of the center rail G3. A force (black arrow X in FIG. 1) that pushes the roller 6a to the rail guide portion 34 on the vehicle inner side of the rail upper portion 31 acts on the vehicle inner side, whereby the center rail G3 causes the coupling portion F with the concave groove 2 to move. The outside of the vehicle is lifted as the center, and the vehicle is turned to the inside to try to tilt.

本実施形態によれば、センタレールＧ３の後端部の上壁部３７にストッパ部材５を設け、上壁部３７と凹溝２の上面部２１との間隙にストッパ部材５を詰めたので、ストッパ部材５および凹溝２の上面部２１が支えとなってセンタレールＧ３の傾倒を抑制することができる。特にストッパ部材５を上壁部３７の車外側の位置に設けたので効率的にセンタレールＧ３の傾倒を抑制することができる。従ってセンタレールＧ３に対する水平ローラー６ａの位置関係が変化ないから、センタローラーＲ３が脱落することがない。   According to the present embodiment, the stopper member 5 is provided on the upper wall portion 37 of the rear end portion of the center rail G3, and the stopper member 5 is packed in the gap between the upper wall portion 37 and the upper surface portion 21 of the concave groove 2. The stopper member 5 and the upper surface portion 21 of the concave groove 2 are supported, and the tilt of the center rail G3 can be suppressed. In particular, since the stopper member 5 is provided at a position outside the vehicle on the upper wall portion 37, the tilt of the center rail G3 can be efficiently suppressed. Therefore, since the positional relationship of the horizontal roller 6a with respect to the center rail G3 does not change, the center roller R3 does not fall off.

センタレールＧ３の傾倒を抑制することで、水平ローラー６ａを支持してアーム部材６０の先端に結合された縦軸６１の姿勢は変化しないから、スライドドアの強開時にアーム部材６０が上方へ移動しないので、アーム部材６０がクォータウィンドウガラス７の下縁７１に当ってこれを破損するおそれがない。従って、クォータウィンドウガラス７の下縁７１と凹溝２の開口下縁との上記間隙を可及的に狭くすることができ、上記間隙が目立たず見栄えをよくできる。   By suppressing the tilt of the center rail G3, the posture of the vertical axis 61 that supports the horizontal roller 6a and is coupled to the tip of the arm member 60 does not change, so the arm member 60 moves upward when the sliding door is forcibly opened. Therefore, there is no possibility that the arm member 60 hits the lower edge 71 of the quarter window glass 7 and breaks it. Therefore, the gap between the lower edge 71 of the quarter window glass 7 and the lower edge of the opening of the concave groove 2 can be made as narrow as possible, and the gap is not conspicuous and the appearance can be improved.

図３は本発明の他の実施形態を示すもので、本実施形態の構造は、センタレールＧ３の後端部の上壁部３７に設けたストッパ部材５の上端面５１と、凹溝２の上面部２１とを僅少の間隙Ｅをおいて対向せしめてある。ストッパ部材５の上端面５１は凹溝２の上面部２１の下面と平行面をなし、両者の間隔は２mm以下に設定してある。その他の基本構造は際の実施形態のそれと同一構造である。   FIG. 3 shows another embodiment of the present invention. The structure of this embodiment includes an upper end surface 51 of the stopper member 5 provided on the upper wall portion 37 of the rear end portion of the center rail G3, and the groove 2 The upper surface portion 21 is opposed to the upper surface portion 21 with a slight gap E. The upper end surface 51 of the stopper member 5 is parallel to the lower surface of the upper surface portion 21 of the concave groove 2, and the distance between them is set to 2 mm or less. The other basic structure is the same as that of the particular embodiment.

一般に、車両の製造ラインにおいて車体はセンタレールが組付けられた状態で電着塗装がなされる。この場合、ストッパ部材５が凹溝２の上面部２１に接触した状態では上面部２１の塗装が不完全となる。本実施形態によりストッパ部材５と上面部２１との間に間隙Ｅを設けることで、凹溝２を完全に塗装することができる。   Generally, in a vehicle production line, a vehicle body is subjected to electrodeposition coating with a center rail assembled. In this case, when the stopper member 5 is in contact with the upper surface portion 21 of the concave groove 2, the coating of the upper surface portion 21 is incomplete. By providing the gap E between the stopper member 5 and the upper surface portion 21 according to this embodiment, the groove 2 can be completely painted.

スライドドアの強開操作時には、先の実施形態とほぼ同様な作用効果が発揮され、センタレールＧ３の傾倒を抑制することができる。なお、先の実施形態に比べると、本実施形態ではストッパ部材５と凹溝２の上面部２１との間に間隙を設けた分、センタレールＧ３は傾倒することとなるが、その変形は微小ですみ、センタレールＧ３からのセンタローラーＲ３の脱落防止や、クォータウィンドウガラスの破損防止効果に影響しない。
またストッパ部材５はその上端面５１を凹溝２の上面部２１と平行に形成したので、センタレールＧ３の傾倒はストッパ部材５を介して凹溝２の上面部２１に効率よく受け止められる。 When the sliding door is forcibly opened, the same effects as those of the previous embodiment are exhibited, and the tilt of the center rail G3 can be suppressed. Compared to the previous embodiment, in this embodiment, the center rail G3 tilts as much as the gap is provided between the stopper member 5 and the upper surface portion 21 of the concave groove 2, but the deformation is small. It does not affect the effect of preventing the center roller R3 from falling off the center rail G3 and the effect of preventing the quarter window glass from being damaged.
Further, since the stopper member 5 has the upper end surface 51 formed in parallel with the upper surface portion 21 of the concave groove 2, the tilt of the center rail G <b> 3 is efficiently received by the upper surface portion 21 of the concave groove 2 through the stopper member 5.

一般に、センタレールの後端部には多くの場合、補強部材が設けられており、本発明の実施形態でもストッパ部材５を補強部材３６の上面に設けたが、これに限るものではなく、補強部材が設けられない車種においてはセンタレールの上面に直接、ストッパ部材を設けてもよい。   In general, the rear end portion of the center rail is often provided with a reinforcing member. In the embodiment of the present invention, the stopper member 5 is provided on the upper surface of the reinforcing member 36. However, the present invention is not limited to this. In a vehicle type in which no member is provided, a stopper member may be provided directly on the upper surface of the center rail.
