Abstract

[Problem] To provide a guide structure of a sunroof panel at low cost. [Solution] A guide rail (9) of a guide structure (4), which movably supports a sunroof panel, is configured from a metal guide rail (7) and a resin guide rail (8). Slide grooves (23, 25), which allow sliding of a panel bracket (13) which is a member to be guided, and raising/lowering guide grooves (28), which allow tilting of the panel bracket (13), are formed in the resin guide rail (8). The metal guide rail reinforces the resin guide rail to ensure rigidity. Because there is no need to form a complicated shape for supporting the panel bracket in the metal guide rail, the metal guide rail can be formed by folding and bending sheet metal, and manufacturing costs can be kept low.

Description

サンルーフパネル用のガイドレール及びその製造方法、並びにサンルーフパネルのガイド構造Guide rail for sunroof panel, method for manufacturing the same, and guide structure for sunroof panel
 本開示は、サンルーフパネルを摺動及び昇降可能に支持するガイドレール及びその製造方法、並びにガイド構造に関する。 The present disclosure relates to a guide rail that supports a sunroof panel so as to be slidable and liftable, a manufacturing method thereof, and a guide structure.
 車両等のルーフ(屋根)を開閉するべく、ルーフの開口に取り付けられたサンルーフパネルを開閉可能に支持するガイド構造として、例えば特許文献1に記載の構造が知られている。特許文献1のガイド構造は、サンルーフパネルを変位可能に支持し、サンルーフパネルは、ルーフの開口を閉じた閉位置、閉位置から後部がチルトアップして開口した位置、及び閉位置から後部がチルトダウンした後に後方にスライド移動して開口した位置の間で変位する。ガイドレールは2段になっており、その下段側を駆動モータに駆動される後部スライダが摺動し、その上段をルーフパネルが取り付けられて後部スライダに連結したパネルブラケットが摺動する。パネルブラケットは、所定の範囲で後部スライダと共に摺動し、所定の範囲の前端では、カム機構によって後部スライダの摺動に伴ってチルトアップする。そのため、上段のレールは、パネルブラケットがチルトアップできるように上方に向かって開放している。従来、このような複雑な形状のガイドレールは、アルミニウム合金を押し出し成形したものを加工して形成されていた。 For example, a structure described in Patent Document 1 is known as a guide structure that supports a sunroof panel attached to an opening of a roof so that the roof (roof) of a vehicle can be opened and closed. The guide structure of Patent Document 1 supports the sunroof panel so that the sunroof panel can be displaced. The sunroof panel has a closed position in which the opening of the roof is closed, a position in which the rear part is tilted up from the closed position, and a rear part is tilted from the closed position. After moving down, it slides backward and displaces between the open positions. The guide rail has two stages, and a rear slider driven by a drive motor slides on the lower side of the guide rail, and a panel bracket connected to the rear slider slides on an upper stage of the guide rail. The panel bracket slides with the rear slider within a predetermined range, and at the front end of the predetermined range, the panel bracket is tilted up as the rear slider slides by the cam mechanism. Therefore, the upper rail is opened upward so that the panel bracket can be tilted up. Conventionally, such a complicated guide rail has been formed by processing an extruded aluminum alloy.
 特許文献2に記載のガイドレール構造は、アルミニウム合金の押し出し成形品からなるレール本体に樹脂成形部品からなるレールを嵌合させたものである。金属で形成された摺動部材が、アルミニウム合金からなるレール本体ではなく樹脂成形部品を摺動するため、摺動時の異音の発生や、ガイドレールの表面処理の削れ等が防がれる。 The guide rail structure described in Patent Document 2 is obtained by fitting a rail made of a resin molded part to a rail body made of an extruded product of an aluminum alloy. Since the sliding member made of metal slides on the resin molded part instead of the rail body made of an aluminum alloy, it is possible to prevent the generation of abnormal noise during sliding and the shaving of the surface treatment of the guide rail.

 しかしながら、アルミニウム合金による押し出し成形は、材料及び加工コストが高かった。また、特許文献2に記載のガイド構造では、アルミニウム合金からなるレール本体が複雑な形状であるため、樹脂成形部品をレール本体に取り付ける作業が煩雑であり、組立作業のコストが増加する原因となっていた。本発明は、このような背景を鑑みてなされたもので、低コストで製造できるサンルーフパネルのガイドレール、ガイド構造及びその製造方法を提供することを目的とする。 However, extrusion molding with an aluminum alloy has a high material and processing cost. Moreover, in the guide structure described in Patent Document 2, since the rail body made of an aluminum alloy has a complicated shape, the work of attaching the resin molded part to the rail body is complicated, which causes an increase in the cost of the assembly work. It was. The present invention has been made in view of such a background, and an object of the present invention is to provide a sunroof panel guide rail, a guide structure, and a manufacturing method thereof that can be manufactured at low cost.

Alternatively, a resin guide rail having a metal guide rail (7, 107) including a plurality of metal bent products and a sliding guide groove (23, 25, 123) fitted in the channel and extending in the longitudinal direction. (8, 108). Another aspect of the present invention is a guide structure (4) for movably supporting the sunroof panel (6), having a channel (15) along the longitudinal direction, and one or a plurality of metal bending processes. Metal guide rails (7, 107) including a product, a resin guide rail (20) fitted in the channel and having a guide portion (26) along the longitudinal direction, and a panel bracket attached to the sunroof panel (13), a slider (12) for interlocking the panel bracket, and a sliding member (10) fixed to the slider and sliding in the longitudinal direction inside the guide portion. . Further, an embodiment of the present invention is a method for manufacturing a guide rail (9, 109) for guiding a guided member (13) for moving the sunroof panel (6), and is formed by bending a sheet metal. Creating a metal guide rail (7, 107) comprising at least one metal rail substrate (16, 17, 116) and having a channel (15) along the longitudinal direction; and a guide along the longitudinal direction. And attaching a resin guide rail (8, 108) having portions (23, 25, 26, 123) to the metal rail base so as to be disposed in the channel.
 これらの構成によれば、樹脂ガイドレールによってガイドレールの主要部である摺動ガイド溝又はガイド部が作成され金属レールによってその剛性を補強されている。そのため、金属ガイドレールの構造が折り曲げ加工によって製造できるほど簡素となり、加工コストを抑制することができる。また、押し出し加工に比べて金属ガイドレールの材料の選択の幅が拡がり、安価な材料を選択して材料コストを抑制することができる。さらに、パネルブラケット等の被ガイド部材又は摺動部材は樹脂ガイドレールに対して摺動するため、金属ガイドレールは被ガイド部材又は摺動部材の摺動部分による摩耗の影響を受けない。 According to these configurations, the sliding guide groove or guide part, which is the main part of the guide rail, is created by the resin guide rail, and its rigidity is reinforced by the metal rail. Therefore, the structure of the metal guide rail becomes simple enough to be manufactured by bending, and the processing cost can be suppressed. Moreover, the range of selection of the material for the metal guide rail is expanded as compared with the extrusion processing, and an inexpensive material can be selected to suppress the material cost. Furthermore, since the guided member or sliding member such as the panel bracket slides with respect to the resin guide rail, the metal guide rail is not affected by wear by the sliding portion of the guided member or sliding member.
 本発明の他の実施形態は、上記構成において、前記被ガイド部材の少なくとも一端側が前記摺動ガイド溝に対して出没する昇降をガイドするべく、前記樹脂ガイドレール(20)は、前記摺動ガイド溝に連通する昇降ガイド溝(28)を含む昇降ガイド部(29)を有することを特徴とする。 In another embodiment of the present invention, in the above configuration, the resin guide rail (20) is configured to guide the elevating and lowering of at least one end of the guided member relative to the sliding guide groove. It has the raising / lowering guide part (29) containing the raising / lowering guide groove (28) connected to a groove | channel.
 この構成によれば、樹脂レールが摺動用の溝と昇降用の溝とを含むため、組み立てコストを抑制することができる。 According to this configuration, since the resin rail includes the sliding groove and the lifting groove, the assembly cost can be suppressed.
 本発明の他の実施形態は、上記構成において、前記金属ガイドレールは、2つの前記金属製折り曲げ加工品からなる1対の金属レール基材(16,17,116)を含み、前記1対の金属レール基材は互いに長尺方向に沿って固定されていることを特徴とする。 According to another embodiment of the present invention, in the above configuration, the metal guide rail includes a pair of metal rail base materials (16, 17, 116) made of the two bent metal products. The metal rail base materials are fixed to each other along the longitudinal direction.
 この構成によれば、1枚の板金から複雑な折り曲げ加工を施して金属ガイドレールを形成する場合に比べて容易に金属ガイドレールを成形することができる。また、2つの金属レール基材の固定を後で行うことにより、樹脂ガイドレールの金属ガイドレールへの取りつけが、長尺方向に直交する方向から行えるため、組み立て作業が容易となり、組み立てコストを抑制することができる。 According to this configuration, the metal guide rail can be easily formed as compared with the case where the metal guide rail is formed by performing a complicated bending process from one sheet metal. Also, by fixing the two metal rail bases later, the resin guide rail can be attached to the metal guide rail from the direction perpendicular to the longitudinal direction, making assembly work easier and reducing assembly costs. can do.
 本発明の他の実施形態は、上記構成において、前記1対の金属レール基材の少なくとも一方(16,116)は、前記1対の金属レール基材の他方に向かって延出して該他方に固定されている複数のタブ(16d,116d)を有することを特徴とする。 According to another embodiment of the present invention, in the above configuration, at least one of the pair of metal rail bases (16, 116) extends toward the other of the pair of metal rail bases. It has a plurality of fixed tabs (16d, 116d).
 この構成によれば、重ね合わせる領域が減少するためガイドレールが軽量化されると共に、材料コストを抑制することができる。 According to this configuration, since the overlapping area is reduced, the guide rail is reduced in weight and the material cost can be suppressed.

 以下、図面を参照しながら、本発明の実施形態を説明する。図1に示すように、サンルーフ装置1は、車両2のルーフ3に取り付けられる。サンルーフ装置1は、車両2に取り付けられたガイド構造4と、ガイド構造4に可動に支持されてルーフ3の開口5を開閉するサンルーフパネル6とを備える。以下の説明において、前後、左右及び上下の方向は、車両2の前後、左右及び上下の方向と一致する図に示す方向に従う。サンルーフパネル6は、ルーフ3の開口5を閉じた閉位置と後部がチルトアップして開口5が開いた位置との間、及び閉位置と後部がチルトダウンした後に後方にスライド移動して開口5が前側から開いた位置との間で変位する。サンルーフパネル6は、例えば板ガラス等から形成されて、その周縁には開口5とのシール性を確保するために、弾性材からなるウェザーストリップ6aが全周に渡って設置されている。図2は、ガイド構造4の内、開口5の左側に設けられた部分を示す。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the sunroof device 1 is attached to the roof 3 of the vehicle 2. The sunroof device 1 includes a guide structure 4 attached to the vehicle 2 and a sunroof panel 6 that is movably supported by the guide structure 4 and opens and closes the opening 5 of the roof 3. In the following description, the front-rear, left-right, and up-down directions follow the directions shown in the drawings that match the front-rear, left-right, up-down directions of the vehicle 2. The sunroof panel 6 slides backward between the closed position where the opening 5 of the roof 3 is closed and the position where the rear part is tilted up and the opening 5 is opened, and after the closed position and the rear part are tilted down. Is displaced between the position opened from the front side. The sunroof panel 6 is formed of, for example, plate glass or the like, and a weather strip 6a made of an elastic material is installed on the entire periphery of the sunroof panel 6 in order to ensure the sealing property with the opening 5. FIG. 2 shows a portion of the guide structure 4 provided on the left side of the opening 5.
 まず、ガイド構造4の全体構造を説明する。図1~図4に示すように、ガイド構造4は、金属ガイドレール7及び金属ガイドレール7の内側に固定された樹脂ガイドレール8からなる左右1対のガイドレール9と、左右1対のラックベルト10を介して駆動モータ11に駆動されてガイドレール9を摺動する左右1対のスライダ12と、サンルーフパネル6が取り付けられ、スライダ12に連結してガイドレール9にガイドされる被ガイド部材である左右1対のパネルブラケット13とを備える。パネルブラケット13は、スライダ12に連動する。スライダ12がガイドレール9の摺動可能範囲の前部を摺動するとき、スライダ12及びパネルブラケット13に設けられたカム機構14によって、パネルブラケット13が後端側が上下に円弧状に動くように傾動し、それにより、サンルーフパネル6は、開口5が閉じた閉位置を挟んで後端側が閉位置からチルトアップした位置と後端側が閉位置からチルトダウンした位置との間で変位する。スライダ12がガイドレール9の摺動可能範囲の後部を摺動するとき、後端側がチルトダウンした状態のパネルブラケット13がガイドレール9に案内されることによって、サンルーフパネル6は、ルーフ3の外層パネルと内装パネルとの間に収容され又は離脱する。 First, the overall structure of the guide structure 4 will be described. As shown in FIGS. 1 to 4, the guide structure 4 includes a pair of left and right guide rails 9 each including a metal guide rail 7 and a resin guide rail 8 fixed inside the metal guide rail 7, and a pair of left and right racks. A pair of left and right sliders 12 that are driven by a drive motor 11 via a belt 10 to slide on a guide rail 9 and a sunroof panel 6 are attached, and are guided by the guide rail 9 by being connected to the slider 12. And a pair of left and right panel brackets 13. The panel bracket 13 is interlocked with the slider 12. When the slider 12 slides in the front part of the slidable range of the guide rail 9, the cam mechanism 14 provided on the slider 12 and the panel bracket 13 causes the panel bracket 13 to move up and down in a circular arc shape. As a result, the sunroof panel 6 is displaced between a position where the rear end side is tilted up from the closed position and a position where the rear end side is tilted down from the closed position across the closed position where the opening 5 is closed. When the slider 12 slides in the rear part of the slidable range of the guide rail 9, the panel bracket 13 whose rear end side is tilted down is guided to the guide rail 9, so that the sunroof panel 6 is It is accommodated or detached between the panel and the interior panel.
 次に、ガイド構造4の各部材の詳細な構造について説明する。ガイド構造4は、概ね左右対称であり、例えば、左右1対のガイドレール9は、ルーフ3の開口5の左右両側辺に取り付けられる。よって、以下の各部材の詳細な構造の説明では、特に断わらない限り、左側の部材について説明する。右側の部材は、左側の部材の説明における左右を逆にした構成に相当する。 Next, the detailed structure of each member of the guide structure 4 will be described. The guide structure 4 is generally bilaterally symmetric. For example, a pair of left and right guide rails 9 are attached to the left and right sides of the opening 5 of the roof 3. Therefore, in the following description of the detailed structure of each member, the left member will be described unless otherwise specified. The member on the right side corresponds to a configuration in which the left and right in the description of the left member are reversed.
 ガイドレール9は、スライダ12及びパネルブラケット13をガイドするための部分的形状のほとんどが樹脂ガイドレール8によって形成され、剛性が金属ガイドレール7によって補強されている。 The guide rail 9 is mostly formed of a resin guide rail 8 for partially guiding the slider 12 and the panel bracket 13, and its rigidity is reinforced by the metal guide rail 7.
 金属ガイドレール7は、前後方向に延びる長尺部材であって、前後方向に沿ってチャネル15が形成されている。金属ガイドレール7は、左右に別体の2つの基材、すなわち、車両2に対して左右方向の内側に配置される第1金属レール基材16と左右方向の外側に配置される第2金属レール基材17とを接合させて形成される。第1金属レール基材16及び第2金属レール基材17の各々は、板金の折り曲げ加工によって形成された金属製折り曲げ加工品である。板金としては、溶融亜鉛メッキ鋼板が好適であるが、その他の鋼板や金属板を使用してもよい。 The metal guide rail 7 is a long member extending in the front-rear direction, and a channel 15 is formed along the front-rear direction. The metal guide rail 7 has two separate base materials on the left and right sides, that is, a first metal rail base material 16 disposed on the inner side in the left-right direction with respect to the vehicle 2 and a second metal disposed on the outer side in the left-right direction. It is formed by joining the rail base material 17. Each of the first metal rail base material 16 and the second metal rail base material 17 is a metal bent product formed by bending a sheet metal. As the sheet metal, a hot-dip galvanized steel plate is suitable, but other steel plates and metal plates may be used.
 図2に示すように、第1金属レール基材16は、下壁16aと、下壁16aの右端に立設された側壁16bと、側壁16bの上端に左方に向けて延設されたリップ壁16cとを有する。下壁16aの左側には、左方に延出する複数のタブ16dが形成されている。第2金属レール基材17は、下壁17aと、下壁17aの左端に立設された側壁17bと、側壁17bの上端に右方に向けて延設されたリップ壁17cとを有する。下壁17aの右端は前後方向に延びているが、第1金属レール基材16のタブ16dに対応する位置にタブを設けるように変更してもよい。図3に示すように、第1金属レール基材16の下壁16aを、第2金属レール基材17の下壁17aの右端側に重ね合わせ、タブ16dとタブ16dに重なった下壁17aとをかしめることによって、第1金属レール基材16と第2金属レール基材17とは互いに結合される。タブ16dが形成されたかしめ部以外の部分では、第1金属レール基材16の下壁16aと第2金属レール基材17の下壁17aとの重なり幅は小さい。すなわち、金属ガイドレール7は、第1金属レール基材16においてかしめ部以外の形状が縮小されているため軽量化されている。リップ壁16c,17cは、対応する下壁16a,17aよりも左右方向幅が短いため、金属ガイドレール7の上面は、前後方向に帯状に開口している。 As shown in FIG. 2, the first metal rail base 16 includes a lower wall 16a, a side wall 16b standing at the right end of the lower wall 16a, and a lip extending leftward at the upper end of the side wall 16b. And a wall 16c. A plurality of tabs 16d extending leftward are formed on the left side of the lower wall 16a. The second metal rail base member 17 includes a lower wall 17a, a side wall 17b erected at the left end of the lower wall 17a, and a lip wall 17c extending rightward at the upper end of the side wall 17b. The right end of the lower wall 17a extends in the front-rear direction, but may be changed so that a tab is provided at a position corresponding to the tab 16d of the first metal rail base 16. As shown in FIG. 3, the lower wall 16a of the first metal rail base material 16 is overlapped on the right end side of the lower wall 17a of the second metal rail base material 17, and the tab 16d and the lower wall 17a overlapping the tab 16d By caulking, the first metal rail base material 16 and the second metal rail base material 17 are coupled to each other. In a portion other than the caulking portion where the tab 16d is formed, the overlapping width of the lower wall 16a of the first metal rail base material 16 and the lower wall 17a of the second metal rail base material 17 is small. That is, the metal guide rail 7 is reduced in weight because the shape of the first metal rail base 16 other than the caulking portion is reduced. Since the lip walls 16c and 17c have a shorter width in the left-right direction than the corresponding lower walls 16a and 17a, the upper surface of the metal guide rail 7 is opened in a strip shape in the front-rear direction.
 樹脂ガイドレール8は、ポリプロピレン等の樹脂を素材とし、射出成形あるいは押出成形される。図2及び図3に示すように、樹脂ガイドレール8は、第1金属レール基材16の内側に嵌合される第1樹脂レール19と、第2金属レール基材17の内側に嵌合される第2樹脂レール20とからなる。 The resin guide rail 8 is made of a resin such as polypropylene and is injection molded or extruded. As shown in FIGS. 2 and 3, the resin guide rail 8 is fitted inside the first metal rail base 16 and the first resin rail 19 fitted inside the first metal rail base 16. Second resin rail 20.
 第1樹脂レール19は、断面視で概ね左右方向の左側に向かって開口したコ字形状をなす。第1樹脂レール19のコ字形状の外面が概ね第1金属レール基材16の内面に当接するように、第1樹脂レール19は、第1金属レール基材16に嵌合している。第1樹脂レール19の上側左端は、第1金属レール基材16のリップ壁16cの左端よりも左方に延出している。第1樹脂レール19は、リベット21により第1金属レール基材16に固定される。第1樹脂レール19と第1金属レール基材16とは、互いに係合形状を付与することで固定される構造としてもよい。第1樹脂レール19のコ字形状の内面は、前後方向に沿った溝となっており、スライダ12の下部内側に設けられた内側スライド部22を摺動させる第1摺動溝23を構成する。 The first resin rail 19 has a U-shape that is open toward the left side in the left-right direction in a cross-sectional view. The first resin rail 19 is fitted to the first metal rail base material 16 so that the U-shaped outer surface of the first resin rail 19 is substantially in contact with the inner surface of the first metal rail base material 16. The upper left end of the first resin rail 19 extends to the left from the left end of the lip wall 16 c of the first metal rail base 16. The first resin rail 19 is fixed to the first metal rail base 16 by rivets 21. The 1st resin rail 19 and the 1st metal rail base material 16 are good also as a structure fixed by giving an engagement shape mutually. The U-shaped inner surface of the first resin rail 19 is a groove extending in the front-rear direction, and constitutes a first sliding groove 23 that slides the inner slide portion 22 provided on the lower inner side of the slider 12. .
 第2樹脂レール20は、断面視で左右方向の右側に向かって開口している。第2樹脂レール20の外面が概ね第2金属レール基材17の内面に当接するように、第2樹脂レール20は、第2金属レール基材17に嵌合している。第2樹脂レール20は、リベット21により第2金属レール基材17に固定される。第2樹脂レール20と第2金属レール基材17とは、互いに係合形状を付与することで固定される構造としてもよい。第2樹脂レール20の内面によって画定される溝状の空間は、この溝状空間の開口に近い側(左右方向右側)が、スライダ12の下部外側に設けられた外側スライド部24を摺動させる第2摺動溝25を構成し、溝状空間の開口から離れた側が、ラックベルト10を保持してその前後方向の動きをガイドするベルトガイド部26を構成する。第2摺動溝25とベルトガイド部26との間には上下に段差があり、ベルトガイド部26の方が上下方向において広くなっている。第2摺動溝25を画定する部分は、第2金属レール基材17のリップ壁17cの右端よりも右方(左右方向右側)に設けられる。また、この部分の外面の上面及び下面には、それぞれ、肉抜き27が形成されている。 The second resin rail 20 is open toward the right side in the left-right direction in a cross-sectional view. The second resin rail 20 is fitted to the second metal rail base material 17 so that the outer surface of the second resin rail 20 substantially contacts the inner surface of the second metal rail base material 17. The second resin rail 20 is fixed to the second metal rail base material 17 by rivets 21. The 2nd resin rail 20 and the 2nd metal rail base material 17 are good also as a structure fixed by giving an engagement shape mutually. The groove-like space defined by the inner surface of the second resin rail 20 is such that the side close to the opening of the groove-like space (the right side in the left-right direction) slides the outer slide portion 24 provided on the lower outer side of the slider 12. The side that forms the second sliding groove 25 and is away from the opening of the groove-like space constitutes a belt guide portion 26 that holds the rack belt 10 and guides its movement in the front-rear direction. There is a step difference between the second sliding groove 25 and the belt guide portion 26, and the belt guide portion 26 is wider in the vertical direction. The portion that defines the second sliding groove 25 is provided on the right side (right side in the left-right direction) of the right end of the lip wall 17c of the second metal rail base member 17. In addition, on the upper surface and the lower surface of the outer surface of this portion, a lightening 27 is formed, respectively.
 また、図2に示すように、第2樹脂レール20は、パネルブラケット13の昇降をガイドする昇降ガイド溝28が形成された昇降ガイド部29を備える。昇降ガイド部29は、第2摺動溝25及びベルトガイド部26を形成する本体部30と一体に射出成形される。また、本体部30を押し出し成形し、昇降ガイド部29を本体部30と別体として成形し、両者を組み合わせてもよい。昇降ガイド部29は、パネルブラケット13の後端近傍に設けられた後部被ガイド片31aをガイドする後部昇降ガイド部29aと、パネルブラケット13の前端側に設けられた前部被ガイド片31bをガイドする前部昇降ガイド部29bとを含む。パネルブラケット13は、前部被ガイド片31bよりも前端側に形成されたスライダ部32を軸にして、後端側が昇降するように傾動する。 Further, as shown in FIG. 2, the second resin rail 20 includes an elevating guide portion 29 in which an elevating guide groove 28 for guiding the elevating of the panel bracket 13 is formed. The raising / lowering guide part 29 is injection-molded integrally with the main body part 30 that forms the second sliding groove 25 and the belt guide part 26. Alternatively, the main body 30 may be extruded and the elevating guide 29 may be formed separately from the main body 30 and the two may be combined. The raising / lowering guide part 29 guides the rear raising / lowering guide part 29a which guides the rear guided piece 31a provided in the vicinity of the rear end of the panel bracket 13, and the front guided piece 31b provided on the front end side of the panel bracket 13. And a front raising / lowering guide portion 29b. The panel bracket 13 tilts so that the rear end side moves up and down around the slider portion 32 formed on the front end side with respect to the front guided piece 31b.
 後部昇降ガイド部29aは、閉位置の近傍においてパネルブラケット13の上昇及び下降をガイドする。後部昇降ガイド部29aに設けられた後部昇降ガイド溝28aは、第2摺動溝25と連通しており、上下方向に延在する。後部昇降ガイド溝28aの前後方向幅は、第2摺動溝25と連通する下端側において後部被ガイド片31aの前後方向幅と略等しく、上端側は下端側よりもわずかに広く設定されており、下降してくる後部被ガイド片31aの前後方向の位置のずれを許容する。後部昇降ガイド部29aは、下端側においては第2摺動溝25の上下方向幅を狭めないが、上端側においては第2樹脂レール20の本体部30の上面よりも上方に延出している。この上方に延出した部分の上面は、前方に向かうにつれて上方に向かうように湾曲又は傾斜しており、パネルブラケット13の後端側に設けられた衝当片33が衝き当たって摺動する衝当面34を構成している。衝当面34は、前後に凹状になるように湾曲することが好ましい。開口5の前側が開いた位置からパネルブラケット13の前方への移動に伴ってサンルーフパネル6が閉位置に変位するとき、衝当片33が衝当面34に衝き当たって摺動することにより、打音が軽減される。 The rear raising / lowering guide part 29a guides the raising and lowering of the panel bracket 13 in the vicinity of the closed position. The rear lifting guide groove 28a provided in the rear lifting guide part 29a communicates with the second sliding groove 25 and extends in the vertical direction. The front-rear direction guide groove 28a has a front-rear width that is substantially equal to the front-rear direction width of the rear guided piece 31a on the lower end side communicating with the second sliding groove 25, and the upper end side is set slightly wider than the lower end side. In this case, the rear guided piece 31a is allowed to shift in the front-rear direction. The rear lifting guide portion 29 a does not narrow the vertical width of the second sliding groove 25 on the lower end side, but extends upward from the upper surface of the main body portion 30 of the second resin rail 20 on the upper end side. The upper surface of the upwardly extending portion is curved or inclined so as to go upward as it goes forward, and the impact piece 33 provided on the rear end side of the panel bracket 13 impacts and slides. It constitutes 34 for the time being. The abutting surface 34 is preferably curved so as to be concave in the front-rear direction. When the sunroof panel 6 is displaced to the closed position as the panel bracket 13 is moved forward from the position where the front side of the opening 5 is opened, the impact piece 33 strikes the impact surface 34 and slides. Sound is reduced.
 前部昇降ガイド部29bは、サンルーフパネル6が閉位置と後部がチルトアップした位置との間を変位するときに、パネルブラケット13の昇降動作全体をガイドする。前部昇降ガイド溝28bは、第2摺動溝25と連通しており、上下方向に延在する。また、前部昇降ガイド溝28bは、パネルブラケット13の後部が上昇するときはスライダ部32がわずかに後方に摺動し、パネルブラケット13の後部が下降するときはスライダ部32がわずかに前方に摺動するように、上方に向かうにつれて後方に向かうように湾曲している。前部昇降ガイド溝28bの前後方向幅は、パネルブラケット13の後部が昇降するときに、前部被ガイド片31bの前後両端が前部昇降ガイド溝28bに摺接するように略一定である。前部昇降ガイド部29bの上端は、第2樹脂レール20の本体部30の上面よりも上方に延出している。また、前部昇降ガイド溝28bを形成する前部昇降ガイド部29bは、前部被ガイド片31bの前方への移動を規制するべく、前部昇降ガイド溝28bの前側部分のみが第2摺動溝25内に突入するように下方に延出し、パネルブラケット13の上昇開始位置における前方への移動を規制する。 The front lifting guide portion 29b guides the entire lifting operation of the panel bracket 13 when the sunroof panel 6 is displaced between the closed position and the rear tilted position. The front lifting guide groove 28b communicates with the second sliding groove 25 and extends in the vertical direction. Further, the front elevating guide groove 28b is configured such that when the rear portion of the panel bracket 13 is raised, the slider portion 32 slightly slides backward, and when the rear portion of the panel bracket 13 is lowered, the slider portion 32 is slightly forward. As it slides, it curves so that it goes back as it goes up. The front / rear direction width of the front lifting guide groove 28b is substantially constant so that both front and rear ends of the front guided piece 31b are in sliding contact with the front lifting guide groove 28b when the rear portion of the panel bracket 13 is lifted / lowered. The upper end of the front raising / lowering guide part 29 b extends upward from the upper surface of the main body part 30 of the second resin rail 20. Further, the front elevating guide portion 29b forming the front elevating guide groove 28b has the second sliding only the front side portion of the front elevating guide groove 28b so as to restrict the forward movement of the front guided piece 31b. It extends downward so as to enter the groove 25, and restricts forward movement of the panel bracket 13 at the rising start position.
 図3に示すように、第1樹脂レール19と第2樹脂レール20とは、互いに左右方向に離間している。ガイドレール9の組み立ては、第1金属レール基材16に第1樹脂レール19を取り付け、第2金属レール基材17に第2樹脂レール20を取り付けた後に、第1金属レール基材16と第2金属レール基材17とを互いに結合することによりなされる。第1樹脂レール19の第1金属レール基材16への取り付けは、左右方向に作業スペースがあるため、長尺方向である前後方向からではなく、左右方向から行うことができ、第1樹脂レール19の第1金属レール基材16への嵌合、及び両者のリベット21による固定を容易に行うことができる。第2金属レール基材17への第2樹脂レール20の取り付けも同様である。 As shown in FIG. 3, the first resin rail 19 and the second resin rail 20 are separated from each other in the left-right direction. The assembly of the guide rail 9 is performed by attaching the first resin rail 19 to the first metal rail base material 16 and attaching the second resin rail 20 to the second metal rail base material 17, and then the first metal rail base material 16 and the first metal rail base material 16. This is done by joining two metal rail base materials 17 together. The first resin rail 19 can be attached to the first metal rail base 16 from the left-right direction, not from the front-rear direction, which is the long direction, because there is a work space in the left-right direction. 19 can be easily fitted to the first metal rail base 16 and fixed by the rivets 21. The same applies to the attachment of the second resin rail 20 to the second metal rail base material 17.
 図1及び図2に示すように、1対のラックベルト10は、駆動モータ11によって、左右同時に樹脂ガイドレール8のベルトガイド部26の内部を前後に摺動する。スライダ12は、ラックベルト10に固定されており、ラックベルト10の摺動に伴い、樹脂ガイドレール8を前後に摺動する。ラックベルト10に代えて、プッシュプルケーブルを用いてもよい。 As shown in FIGS. 1 and 2, the pair of rack belts 10 slide back and forth within the belt guide portion 26 of the resin guide rail 8 simultaneously by the drive motor 11. The slider 12 is fixed to the rack belt 10 and slides back and forth on the resin guide rail 8 as the rack belt 10 slides. Instead of the rack belt 10, a push-pull cable may be used.
 図3に示すように、スライダ12は、第1樹脂レール19の第1摺動溝23を摺動する内側スライド部22と、内側スライド部22に連結して第2樹脂レール20の第2摺動溝25を摺動する外側スライド部24と、下端側が内側スライド部22に固定されて上端側がガイドレール9よりも上方に延出した第1側壁35と、下端側が外側スライド部24に固定されて上端側がガイドレール9よりも上方に延出した第2側壁36と、第1側壁35及び第2側壁36の上部に両端部を支持されたピン37とを備える。第1側壁35及び第2側壁36は、上部において左右方向に直交する平板状をなし、パネルブラケット13を挟んで対向しており、下部は、上部に対して略直交するように屈折し、それぞれ、内側スライド部22及び外側スライド部24に接合している。内側スライド部22、外側スライド部24、第1側壁35及び第2側壁36は、それぞれ、樹脂又は金属を素材とする。内側スライド部22及び外側スライド部24は、樹脂を素材とすることが好ましい。金属を素材とするピン37は、ガイドレール9よりも上方に配置され、パネルブラケット13に設けられた案内溝38を摺動可能に貫通している。ピン37と案内溝38とによって、カム機構14が構成される。 As shown in FIG. 3, the slider 12 includes an inner slide portion 22 that slides in the first slide groove 23 of the first resin rail 19, and a second slide of the second resin rail 20 that is connected to the inner slide portion 22. An outer slide portion 24 that slides in the moving groove 25, a first side wall 35 whose lower end side is fixed to the inner slide portion 22 and whose upper end side extends above the guide rail 9, and lower end side is fixed to the outer slide portion 24. The second side wall 36 whose upper end side extends above the guide rail 9, and the first side wall 35 and the pin 37 whose both ends are supported on the upper part of the second side wall 36 are provided. The first side wall 35 and the second side wall 36 have a flat plate shape orthogonal to the left-right direction in the upper part, are opposed to each other with the panel bracket 13 interposed therebetween, and the lower part is refracted so as to be substantially orthogonal to the upper part. The inner slide part 22 and the outer slide part 24 are joined. The inner slide part 22, the outer slide part 24, the first side wall 35, and the second side wall 36 are made of resin or metal, respectively. The inner slide part 22 and the outer slide part 24 are preferably made of resin. The pin 37 made of metal is disposed above the guide rail 9 and slidably penetrates a guide groove 38 provided in the panel bracket 13. The pin 37 and the guide groove 38 constitute the cam mechanism 14.
 パネルブラケット13の本体39は、左右方向に略直交する平板状の主壁40と、主壁40の辺縁から左方(外側)に延出するように設けられたフランジ41とを備える。本体39は金属を素材とし、主壁40には案内溝38が形成されている。案内溝38は、上下に湾曲しながら前後方向に延びている。パネルブラケット13は、さらに、後部被ガイド片31a、前部被ガイド片31b、スライダ部32及び衝当片33を備える。後部被ガイド片31a及び前部被ガイド片31bは、第2樹脂レール20の第2摺動溝25に受容されるように左方に突出している。衝当片33は、後部被ガイド片31aよりも後方かつ上方に位置し、第2樹脂レール20の上方に配置されるように左方に突出している。スライダ部32は、フランジ41の前端部分の下方に設けられ、第2樹脂レール20に下面が当接し得るように左右方向位置が設定される。スライダ部32の下面は下に凸になるように前後に湾曲している。後部被ガイド片31a、スライダ部32及び衝当片33は、樹脂からなり本体39の左側(車両方向内側)に取り付けられる。前部被ガイド片31bは、本体39と一体の金属からなり、本体39から左方に突出している。 The main body 39 of the panel bracket 13 includes a flat plate-like main wall 40 that is substantially orthogonal to the left-right direction, and a flange 41 that is provided so as to extend leftward (outside) from the edge of the main wall 40. The main body 39 is made of metal, and a guide groove 38 is formed in the main wall 40. The guide groove 38 extends in the front-rear direction while curving up and down. The panel bracket 13 further includes a rear guided piece 31a, a front guided piece 31b, a slider portion 32, and an abutting piece 33. The rear guided piece 31 a and the front guided piece 31 b protrude to the left so as to be received in the second sliding groove 25 of the second resin rail 20. The abutting piece 33 is located behind and above the rear guided piece 31a and protrudes to the left so as to be disposed above the second resin rail 20. The slider portion 32 is provided below the front end portion of the flange 41, and the position in the left-right direction is set so that the lower surface can contact the second resin rail 20. The lower surface of the slider portion 32 is curved back and forth so as to protrude downward. The rear guided piece 31a, the slider part 32, and the abutting piece 33 are made of resin and attached to the left side of the main body 39 (inward in the vehicle direction). The front guided piece 31b is made of a metal integral with the main body 39 and protrudes leftward from the main body 39.
 カム機構14は、ピン37と案内溝38とによって構成される。スライダ12の摺動範囲の後部においては(図6参照)、ピン37が案内溝38の後端に係止され、パネルブラケット13は、スライダ12と共に、ガイドレール9を前後方向に移動する。このとき、摩擦抵抗を軽減するため、衝当片33はガイドレール9から離間し、後部被ガイド片31a及び前部被ガイド片31bのいずれか一方又は双方が樹脂ガイドレール8に摺接しないことが好ましい。例えば、パネルブラケット13のスライド移動時は、後部被ガイド片31aの上面が第2樹脂レール20の第2摺動溝25に摺接してパネルブラケット13の傾動を規制し、前部被ガイド片31bは第2摺動溝25に受容されるがその壁面から離間し、衝当片33は第2樹脂レール20の上面から離間する。スライダ部32は、その下面が樹脂ガイドレール8に摺接するように配置されているため、パネルブラケット13のスライド移動を安定させるとともに、スライダ部32の金属ガイドレール7への接触が防止されて摩耗が軽減される。なお、パネルブラケット13がスライド移動するとき、後部被ガイド片31a及び前部被ガイド片31bのいずれか一方又は双方の下面が第2摺動溝25に摺動し、スライダ部32がガイドレール9から離間するように設定してもよい。スライダ12の摺動範囲の前部においては(図5参照)、パネルブラケット13は前後方向には略移動せず、ピン37が案内溝38を摺動する。そのため、パネルブラケット13は、スライダ部32が転動する軸となって後部が昇降するように傾動する。 The cam mechanism 14 includes a pin 37 and a guide groove 38. In the rear part of the sliding range of the slider 12 (see FIG. 6), the pin 37 is locked to the rear end of the guide groove 38, and the panel bracket 13 moves along the guide rail 9 in the front-rear direction together with the slider 12. At this time, in order to reduce the frictional resistance, the abutting piece 33 is separated from the guide rail 9 and either one or both of the rear guided piece 31a and the front guided piece 31b do not slide on the resin guide rail 8. Is preferred. For example, when the panel bracket 13 is slid, the upper surface of the rear guided piece 31a is in sliding contact with the second sliding groove 25 of the second resin rail 20 to restrict the tilt of the panel bracket 13 and the front guided piece 31b. Is received in the second sliding groove 25 but is separated from the wall surface thereof, and the abutting piece 33 is separated from the upper surface of the second resin rail 20. Since the slider portion 32 is arranged so that the lower surface thereof is in sliding contact with the resin guide rail 8, the slide movement of the panel bracket 13 is stabilized, and the contact of the slider portion 32 with the metal guide rail 7 is prevented to wear. Is reduced. When the panel bracket 13 slides, the lower surface of one or both of the rear guided piece 31a and the front guided piece 31b slides in the second sliding groove 25, and the slider part 32 moves to the guide rail 9. You may set so that it may space apart from. At the front part of the sliding range of the slider 12 (see FIG. 5), the panel bracket 13 does not substantially move in the front-rear direction, and the pin 37 slides in the guide groove 38. For this reason, the panel bracket 13 tilts so that the rear part moves up and down as an axis on which the slider part 32 rolls.
 次に、図4~図6を参照してサンルーフ装置1の作用について説明する。以下の、作用効果の説明においては、左右1対存在する各部材については、特に断らない限りその両方を指す。図4は、図1のIV-IV断面図、すなわち、第2樹脂レール20の第2摺動溝25とベルトガイド部26との境界で切った断面図であり、サンルーフパネル6が開口5を閉じた閉位置を示す。図5は、図4と同一の断面においてサンルーフパネル6が後方にスライド移動し始めた位置を示し、図6は、図4と同一の断面においてサンルーフパネル6がチルトアップした位置を示す。 Next, the operation of the sunroof device 1 will be described with reference to FIGS. In the following description of the function and effect, each pair of left and right members refers to both unless otherwise specified. 4 is a cross-sectional view taken along the line IV-IV of FIG. 1, that is, a cross-sectional view taken along the boundary between the second sliding groove 25 of the second resin rail 20 and the belt guide portion 26. Indicates closed position. FIG. 5 shows a position where the sunroof panel 6 starts to slide backward in the same cross section as FIG. 4, and FIG. 6 shows a position where the sunroof panel 6 tilts up in the same cross section as FIG.
 図4に示すように、閉位置においては、スライダ12のピン37は、案内溝38の後端からわずかに離間している。サンルーフパネル6を後方にスライド移動させて、ルーフ3の開口5を前側から開放するときは、利用者は、スライダ12が後方に移動するように、駆動モータ11を駆動させる。前部被ガイド片31bの後端が前部昇降ガイド部29bに後方から係止されているため、パネルブラケット13は前後方向には動かず、スライダ12のピン37は、案内溝38内を後方に摺動する。案内溝38は後端付近では後方に向かうにつれて上方に向かっており、かつスライダ12は上下方向への移動が樹脂ガイドレール8の第1摺動溝23及び第2摺動溝25によって規制されるため、パネルブラケット13は後部が下降するように傾動する。このとき、スライダ部32の湾曲した下面が金属ガイドレール7の底面を転動し、後部被ガイド片31aが後部昇降ガイド部29aにガイドされながら下降する。この下降に伴い、パネルブラケット13に取り付けられたサンルーフパネル6は、ルーフ3の外層パネルよりも下方に移動する。 As shown in FIG. 4, in the closed position, the pin 37 of the slider 12 is slightly separated from the rear end of the guide groove 38. When the sunroof panel 6 is slid rearward to open the opening 5 of the roof 3 from the front side, the user drives the drive motor 11 so that the slider 12 moves rearward. Since the rear end of the front guided piece 31b is locked to the front elevating guide portion 29b from the rear, the panel bracket 13 does not move in the front-rear direction, and the pin 37 of the slider 12 moves backward in the guide groove 38. To slide. The guide groove 38 is directed upward in the vicinity of the rear end toward the rear, and the slider 12 is restricted from moving in the vertical direction by the first sliding groove 23 and the second sliding groove 25 of the resin guide rail 8. Therefore, the panel bracket 13 tilts so that the rear part is lowered. At this time, the curved lower surface of the slider portion 32 rolls on the bottom surface of the metal guide rail 7, and the rear guided piece 31a is lowered while being guided by the rear lifting guide portion 29a. As this descends, the sunroof panel 6 attached to the panel bracket 13 moves downward relative to the outer layer panel of the roof 3.
 図5に示すように、前部被ガイド片31bが前部昇降ガイド部29bによる係止から離脱して第2摺動溝25に受容され、後部被ガイド片31aが後部昇降ガイド溝28aを通過して第2摺動溝25に受容され、かつピン37が案内溝38の後端に達すると、ピン37がパネルブラケット13を後方に引き出すことによって、パネルブラケット13は後方に移動する。すると、サンルーフパネル6は後方に移動して、ルーフ3の外層パネルと内装パネルとの間に収容され、開口5が前側から開放される。 As shown in FIG. 5, the front guided piece 31b is released from the locking by the front lifting guide part 29b and is received in the second sliding groove 25, and the rear guided piece 31a passes through the rear lifting guide groove 28a. When the pin 37 is received by the second sliding groove 25 and the pin 37 reaches the rear end of the guide groove 38, the panel 37 moves backward by pulling the panel bracket 13 backward. Then, the sunroof panel 6 moves rearward and is accommodated between the outer layer panel of the roof 3 and the interior panel, and the opening 5 is opened from the front side.
 サンルーフパネル6のスライド移動で開放された開口5を閉じるときは、利用者は、スライダ12が前方に移動するように駆動モータ11を駆動する。後部被ガイド片31aが第2摺動溝25に摺接してパネルブラケット13の傾動を規制するため、ピン37が案内溝38の後端近傍の傾斜した前面を押し込むことによって、パネルブラケット13は前方に移動する。前部被ガイド片31bが前部昇降ガイド部29bに当接すると、パネルブラケット13の前方への移動は規制される。このとき、パネルブラケット13の衝当片33が、後部昇降ガイド部29aの湾曲した衝当面34に突き当たって摺接するため、前部被ガイド片31bと前部昇降ガイド部29bとの衝突が緩和され、打音が軽減される。その後、ピン37は、案内溝38を前方に摺動し、サンルーフパネル6が開口5を塞ぐまでパネルブラケット13を上昇させる。駆動モータ11は、サンルーフパネル6が図4に示す閉位置に戻ると停止する。 When closing the opening 5 opened by the sliding movement of the sunroof panel 6, the user drives the drive motor 11 so that the slider 12 moves forward. Since the rear guided piece 31a is in sliding contact with the second sliding groove 25 to restrict the tilt of the panel bracket 13, the pin 37 pushes the inclined front surface near the rear end of the guide groove 38, so that the panel bracket 13 is moved forward. Move to. When the front guided piece 31b comes into contact with the front lifting guide portion 29b, the forward movement of the panel bracket 13 is restricted. At this time, the abutting piece 33 of the panel bracket 13 abuts against the curved abutting surface 34 of the rear elevating guide portion 29a and comes into sliding contact, so that the collision between the front guided piece 31b and the front elevating guide portion 29b is alleviated. The beating sound is reduced. Thereafter, the pin 37 slides forward in the guide groove 38 and raises the panel bracket 13 until the sunroof panel 6 closes the opening 5. The drive motor 11 stops when the sunroof panel 6 returns to the closed position shown in FIG.
 閉位置からサンルーフパネル6の後部をチルトアップさせて開口5を開放するときは、利用者は、スライダ12が前方に移動するように駆動モータ11を駆動する。前部被ガイド片31bが前部昇降ガイド部29bに前方から係止されるため、パネルブラケット13は前方への移動が規制されている。そのため、ピン37は、案内溝38を前方に摺動する。案内溝38は、前端側が後端側よりも下方に位置するように湾曲しているため、スライダ部32が軸となってパネルブラケット13は後部が上昇するように傾動する。そのため、サンルーフパネル6は、後部がチルトアップし、ピン37が案内溝38の前端に達すると、図6に示すチルトアップ位置になる。 When the rear portion of the sunroof panel 6 is tilted up from the closed position to open the opening 5, the user drives the drive motor 11 so that the slider 12 moves forward. Since the front guided piece 31b is locked to the front lifting guide portion 29b from the front, the panel bracket 13 is restricted from moving forward. Therefore, the pin 37 slides forward in the guide groove 38. Since the guide groove 38 is curved so that the front end side is positioned below the rear end side, the panel bracket 13 tilts with the slider portion 32 as an axis so that the rear portion is raised. Therefore, when the rear portion of the sunroof panel 6 is tilted up and the pin 37 reaches the front end of the guide groove 38, the sunroof panel 6 reaches the tilt-up position shown in FIG.
 サンルーフパネル6をチルトアップ位置から閉位置に戻したいときは、利用者は、スライダ12が後方に移動するように駆動モータ11を駆動する。このとき、パネルブラケット13は、前部被ガイド片31bが前部昇降ガイド部29bに後方から係止されているため、後方に移動することが規制される。そのため、ピン37は、案内溝38を前方に移動して、パネルブラケット13をその後部が下降するように傾動させる。駆動モータ11は、サンルーフパネル6が図4に示す閉位置に戻ると停止する。 When returning the sunroof panel 6 from the tilt-up position to the closed position, the user drives the drive motor 11 so that the slider 12 moves backward. At this time, since the front guided piece 31b is locked to the front lifting guide portion 29b from the rear, the panel bracket 13 is restricted from moving rearward. Therefore, the pin 37 moves the guide groove 38 forward, and tilts the panel bracket 13 so that the rear part thereof is lowered. The drive motor 11 stops when the sunroof panel 6 returns to the closed position shown in FIG.
 樹脂ガイドレール8は、スライダ12及びパネルブラケット13を摺動可能に支持する第1摺動溝23及び第2摺動溝25を形成するとともに、パネルブラケット13を傾動可能に支持するための昇降ガイド溝28を形成している。そのため、金属ガイドレール7は、スライダ12及びパネルブラケット13を摺動又は傾動させるための複雑な形状を備える必要がなく、ガイドレール9の剛性を補強することを主目的として取り付けられる。よって、金属ガイドレール7は、折り曲げ加工によって形成できる簡素な形状とすることができる。また、第1摺動溝23及び第2摺動溝25を1段で形成し、スライダ12及びパネルブラケット13が同じ溝を摺動することとした点も、金属ガイドレール7の形状の簡素化に貢献している。 The resin guide rail 8 forms a first sliding groove 23 and a second sliding groove 25 that slidably support the slider 12 and the panel bracket 13, and a lifting guide for supporting the panel bracket 13 to be tiltable. A groove 28 is formed. Therefore, the metal guide rail 7 does not need to have a complicated shape for sliding or tilting the slider 12 and the panel bracket 13, and is attached for the purpose of reinforcing the rigidity of the guide rail 9. Therefore, the metal guide rail 7 can be made into a simple shape that can be formed by bending. In addition, the first slide groove 23 and the second slide groove 25 are formed in a single stage, and the shape of the metal guide rail 7 is simplified because the slider 12 and the panel bracket 13 slide in the same groove.

 また、第2樹脂レール20は、第2摺動溝25を形成する本体部30と、昇降ガイド部29とが一体成形されるため、組み立て作業が容易となる。さらに、金属ガイドレール7及び樹脂ガイドレール8が左右に2分割された部材から構成されるため、長尺方向ではなく左右方向から、第1樹脂レール19及び第2樹脂レール20を第1金属レール基材16及び第2金属レール基材17に取り付けることができるため、組み立て作業が容易となる。 Moreover, since the main body part 30 and the raising / lowering guide part 29 which form the 2nd sliding groove 25 are integrally molded, the 2nd resin rail 20 becomes easy to assemble. Furthermore, since the metal guide rail 7 and the resin guide rail 8 are composed of members divided into left and right, the first resin rail 19 and the second resin rail 20 are connected to the first metal rail not from the longitudinal direction but from the left and right directions. Since it can attach to the base material 16 and the 2nd metal rail base material 17, an assembly operation becomes easy.
 次に、図7を参照して、変形実施形態について説明する。図7は、開口5(図1参照)の左側に配置されたガイドレール109の図3と同じ位置における断面図である。以下の説明において、上記実施形態と同様の構造及び作用を有する部分については、同一の符号を付し、その説明を省略する。また、上記実施形態と同様に、以下の説明においては開口5の左側に配置された部分について説明する。開口5の右側に配置された部分については、左右の説明が逆となる。変形実施形態は、上記実施形態の第1樹脂レール19に相当する部材がない点で上記実施形態と異なる。 Next, a modified embodiment will be described with reference to FIG. FIG. 7 is a cross-sectional view of the guide rail 109 disposed on the left side of the opening 5 (see FIG. 1) at the same position as FIG. In the following description, parts having the same structure and operation as those of the above embodiment are denoted by the same reference numerals, and the description thereof is omitted. Similarly to the above embodiment, in the following description, a portion disposed on the left side of the opening 5 will be described. About the part arrange | positioned at the right side of the opening 5, the description on either side becomes reverse. The modified embodiment differs from the above embodiment in that there is no member corresponding to the first resin rail 19 of the above embodiment.
 ガイドレール109は、金属ガイドレール107と、金属ガイドレール107に取り付けられた樹脂ガイドレール108とを備えるが、樹脂ガイドレール8は、第2樹脂レール20のみからなる。従って、スライダ12の内側スライド部22は、樹脂ガイドレール108ではなく、金属ガイドレール107の第1金属レール基材116に対して摺動する。第1金属レール基材116は、下壁116aと、下壁116aの右端に立設された側壁116bと、側壁116bの上端に左方に向けて延設されたリップ壁116cとを有し、下壁116aの左側には、左方に延出して第2金属レール基材17に接合される複数のタブ116dが形成されている。下壁116a、側壁116b及びリップ壁116cによって、スライダ12の内側スライド部22が摺動する第1摺動ガイド部123が画成される。下壁116aは、第1摺動ガイド部123を画成する部分と第2金属レール基材17と接合される部分との間に段差が形成されていてもよい。スライダ12の内側スライド部22は、樹脂を素材とすることが好ましく、第1金属レール基材116との摺動による摩耗を軽減するため、グリース等の潤滑剤を用いることが好ましい。 The guide rail 109 includes a metal guide rail 107 and a resin guide rail 108 attached to the metal guide rail 107, but the resin guide rail 8 includes only the second resin rail 20. Therefore, the inner slide portion 22 of the slider 12 slides with respect to the first metal rail base material 116 of the metal guide rail 107 instead of the resin guide rail 108. The first metal rail base material 116 includes a lower wall 116a, a side wall 116b erected at the right end of the lower wall 116a, and a lip wall 116c extending leftward at the upper end of the side wall 116b. On the left side of the lower wall 116a, a plurality of tabs 116d extending leftward and joined to the second metal rail base material 17 are formed. A first sliding guide portion 123 on which the inner slide portion 22 of the slider 12 slides is defined by the lower wall 116a, the side wall 116b, and the lip wall 116c. The lower wall 116 a may have a step formed between a portion that defines the first sliding guide portion 123 and a portion that is joined to the second metal rail base material 17. The inner slide portion 22 of the slider 12 is preferably made of resin, and a lubricant such as grease is preferably used in order to reduce wear due to sliding with the first metal rail base material 116.
 以上で具体的実施形態の説明を終えるが、本発明は上記実施形態に限定されることなく幅広く変形実施することができる。例えば、スライダを介さず、パネルブラケットを摺動及び傾動させてもよい。金属ガイドレールを、1つ又は3つ以上の基材から形成してもよい、樹脂ガイドレールを一体成形された1つの樹脂レールから形成してもよく、第1及び第2樹脂レールを2つ以上の部材から組み立ててもよい。また、本発明に係るガイド構造は、車両のサンルーフだけでなく、家屋等の建築物のサンルーフにも適用できる。 This is the end of the description of the specific embodiment, but the present invention is not limited to the above-described embodiment, and can be widely modified. For example, the panel bracket may be slid and tilted without using a slider. The metal guide rail may be formed from one or three or more base materials, the resin guide rail may be formed from one resin rail integrally formed, and the first and second resin rails are two. You may assemble from the above members. Moreover, the guide structure according to the present invention can be applied not only to a sunroof of a vehicle but also to a sunroof of a building such as a house.
