Description

本発明は、車両の窓枠に沿って装着されて窓ガラスのスライド移動を案内するガラスランチャンネル及びその製造方法に関するものである。   The present invention relates to a glass run channel that is mounted along a window frame of a vehicle and guides sliding movement of the window glass, and a manufacturing method thereof.

一般に、自動車の窓枠構造は、窓枠の内周縁に沿って長尺なガラスランチャンネルを装着し、このガラスランチャンネルによって窓ガラスの昇降移動(スライド移動)を案内するように構成されている。従来のガラスランチャンネルは、ゴム等の弾性ポリマー材料により、窓ガラスの端面に対向する基底部と、この基底部の幅方向両側からそれぞれ立ち上がる車内側及び車外側の側壁部等を一体成形することで、窓ガラスの昇降移動を案内する溝形状に形成したものがあるが、窓ガラスの昇降移動の際に基底部が窓ガラスの端面と接触して擦れるため、基底部が摩耗しやすいという欠点があった。   In general, the window frame structure of an automobile is configured so that a long glass run channel is mounted along the inner peripheral edge of the window frame, and the window glass moves up and down (slide movement) by the glass run channel. . The conventional glass run channel is made of an elastic polymer material such as rubber, and integrally forms the base portion facing the end face of the window glass and the side walls and the like on the vehicle interior and the vehicle exterior rising from both sides in the width direction of the base portion. However, there is one that is formed in a groove shape that guides the window glass up and down movement, but the base part is in contact with the end face of the window glass and rubs when the window glass moves up and down, so that the base part is easily worn was there.

この対策として、特許文献1(特開平10−71649号公報)に記載されているように、ガラスランチャンネルの基底部の表面に、樹脂テープを溶着接合することで、基底部の耐摩耗性を向上させるようにしたものがある。
特開平10−71649号公報(第3頁等)
As a countermeasure against this, as described in Patent Document 1 (Japanese Patent Application Laid-Open No. 10-71649), a resin tape is welded and bonded to the surface of the base portion of the glass run channel, thereby reducing the wear resistance of the base portion. There is something that was made to improve.
Japanese Patent Laid-Open No. 10-71649 (page 3, etc.)

しかし、上記特許文献1の技術では、ガラスランチャンネルの基底部の表面と樹脂テープ等の低摩擦材部の下面とを単に平面同士で密着させて溶着接合するだけであるため、基底部(ガラスランチャンネル本体)を形成する材料と低摩擦材部を形成する材料との相溶性が高くないと、基底部と低摩擦材部との熱溶着(熱融着ということもある)による接合強度を十分に確保することができず、窓ガラスの昇降移動の繰り返しによって基底部から低摩擦材部が剥がれてしまう可能性がある。これにより、低摩擦材部を形成する材料が基底部を形成する材料と相溶性の高い材料に限定されてしまうため、低摩擦材部を形成する材料の選択の自由度が狭くなってしまい、コスト性、成形性等を考慮した幅広い材料選択を行うことができないという欠点があった。   However, in the technique of the above-mentioned Patent Document 1, since the surface of the base portion of the glass run channel and the lower surface of the low friction material portion such as a resin tape are simply brought into close contact with each other by welding, the base portion (glass If the compatibility between the material forming the run channel main body) and the material forming the low friction material part is not high, the bonding strength due to thermal welding (sometimes referred to as thermal fusion) between the base part and the low friction material part is high. There is a possibility that the low-friction material part may be peeled off from the base part due to repeated lifting and lowering movement of the window glass. Thereby, since the material forming the low friction material portion is limited to a material highly compatible with the material forming the base portion, the degree of freedom of selection of the material forming the low friction material portion is narrowed, There was a disadvantage that a wide range of materials could not be selected in consideration of cost and moldability.

本発明は、これらの事情を考慮してなされたものであり、従って本発明の目的は、ガラスランチャンネルの基底部と低摩擦材部との接合強度を十分に確保することができると共に、低摩擦材部を形成する材料の選択の自由度を広げることができるようにすることである。   The present invention has been made in consideration of these circumstances. Therefore, the object of the present invention is to sufficiently secure the bonding strength between the base portion of the glass run channel and the low friction material portion, and to reduce the It is to be able to expand the degree of freedom of selection of the material forming the friction material part.

請求項1に係る発明は、車両の窓枠に沿って装着されて窓ガラスのスライド移動を案内する長尺なガラスランチャンネルであって、弾性変形可能なポリマー材料により形成されて前記窓ガラスの端面と対向する位置に配置される基底部と該基底部の幅方向両側からそれぞれ立ち上がる側壁部とを有するチャンネル本体と、前記窓ガラスに対する摩擦係数が前記チャンネル本体よりも低いポリマー材料により形成されて前記基底部のうち少なくとも前記窓ガラスの端面と対向する部分に溶着接合された低摩擦材部とを備えたガラスランチャンネルを製造する方法において、基底部のうち低摩擦材部との接合部分に、長手方向に延びる凹条と凸条の少なくとも一方を有し、該凹条と該凸条の少なくとも一方によって低摩擦材部に押圧力を作用させる押圧接合部が設けられたチャンネル本体を準備し、基底部を所定の外力により該基底部の内面側が凸面又は凹面となるように該基底部を幅方向に湾曲させる弾性変形工程と、基底部を湾曲させた状態で該基底部に低摩擦材部を積層して溶着接合する溶着接合工程と、溶着接合工程後に外力を除去することで基底部の弾性復元力によって押圧接合部で低摩擦材部に押圧力を作用させる外力除去工程を実行するようにしたものである。このようにすれば、本発明のガラスランチャンネルを効率良く製造することができる。しかも、基底部の弾性復元力によって押圧接合部で基底部と低摩擦材部との接合界面に押圧力を作用させることができるため、基底部(チャンネル本体)を形成する材料と低摩擦材部を形成する材料との相溶性があまり高くなくても、基底部と低摩擦材部との接合強度を高めることができる。これにより、基底部と低摩擦材部との接合強度を十分に確保することができると共に、低摩擦材部を形成する材料の選択の自由度を広げることができ、コスト性、成形性等を考慮した幅広い材料選択を行うことができる。 The invention according to claim 1 is a long glass run channel that is mounted along a window frame of a vehicle and guides the sliding movement of the window glass, and is formed of an elastically deformable polymer material. A channel body having a base portion disposed at a position facing the end face and side wall portions rising from both sides in the width direction of the base portion; and a polymer material having a lower coefficient of friction with respect to the window glass than the channel body. In a method of manufacturing a glass run channel having a low friction material portion welded and bonded to at least a portion facing the end face of the window glass in the base portion, a bonding portion with a low friction material portion in the base portion has at least one concave strip and convex extending in the longitudinal direction, by applying a pressing force to the low-friction material part by at least one of the concave strip and convex Article Prepare the channel body pressing joint is provided, the elastic deformation step of the inner surface side of the base bottom portion to bend the basal part such that the convex or concave in the width direction by a predetermined external force the base portion, the base portion A low-friction material part at the pressure-bonding part due to the elastic restoring force of the base part by removing the external force after the welding-joining process by laminating and joining the low-friction material part on the base part in a curved state An external force removing process is performed in which a pressing force is applied to the . If it does in this way, the glass run channel of the present invention can be manufactured efficiently. In addition, since the pressing force can act on the bonding interface between the base part and the low friction material part by the elastic joint force of the base part, the material forming the base part (channel body) and the low friction material part Even if the compatibility with the material forming the material is not so high, the bonding strength between the base portion and the low friction material portion can be increased. As a result, the bonding strength between the base portion and the low friction material portion can be sufficiently ensured, and the degree of freedom in selecting the material for forming the low friction material portion can be expanded. A wide range of materials can be selected in consideration.

また、請求項のように、押圧接合部には基底部の長手方向に沿って延びる凹条を形成し、弾性変形工程において押圧接合部の凹条を幅方向に拡開させるように基底部を弾性変形させ、溶着接合工程において押圧接合部の凹条を埋めるように低摩擦材部を溶着接合し、外力除去工程において基底部の弾性復元力によって押圧接合部の凹条が幅方向に縮小することで低摩擦材部に押圧力を作用させるようにすると良い。このようにすれば、押圧接合部の凹条で基底部と低摩擦材部との接合界面に押圧力を作用させることができ、基底部と低摩擦材部との接合強度を高めることができる。 According to a second aspect of the present invention, a concave portion extending along the longitudinal direction of the base portion is formed in the press bonding portion, and the base portion is expanded in the width direction in the elastic deformation step. The low friction material part is welded and joined so as to fill the concave part of the press joint part in the welding and joining process, and the concave part of the press joint part is reduced in the width direction by the elastic restoring force of the base part in the external force removing process. By doing so, it is preferable to apply a pressing force to the low friction material portion. If it does in this way, pressing force can be made to act on the joining interface of a base part and a low friction material part with the concave strip of a press joining part, and the joint strength of a base part and a low friction material part can be raised. .

この場合、請求項のように、押圧接合部の凹条は、横断面略U字形状又は横断面略V字形状に形成しても良いが、請求項のように、押圧接合部の凹条は、底部よりも入口部の幅寸法が狭くなるように形成すると良い。このようにすれば、押圧接合部の凹条に入り込んだ低摩擦材部を凹条から抜けにくくすることができ、基底部と低摩擦材部との接合強度を更に高めることができる。 In this case, as in claim 3, concave pressing junction may be formed in cross section substantially U-shaped or cross-section substantially V-shape, as claimed in claim 4, pressing the joint The concave stripe is preferably formed so that the width dimension of the inlet portion is narrower than the bottom portion. In this way, it is possible to make it difficult for the low friction material portion that has entered the recess of the press bonding portion to come out of the recess, and it is possible to further increase the bonding strength between the base portion and the low friction material portion.

また、請求項のように、押圧接合部には基底部の長手方向に沿って延びる複数の凸条を形成し、弾性変形工程において押圧接合部の複数の凸条を幅方向において互いに近付くように基底部を弾性変形させ、溶着接合工程において押圧接合部の凸条が形成されている部分を覆うように低摩擦材部を溶着接合し、外力除去工程において基底部の弾性復元力によって押圧接合部の凸条同士の間隔が幅方向に拡大することで低摩擦材部に押圧力を作用させるようにしても良い。このようにすれば、押圧接合部の凸条で基底部と低摩擦材部との接合界面に押圧力を作用させることができ、基底部と低摩擦材部との接合強度を高めることができる。 Furthermore, as according to claim 5, the pressing joint to form a plurality of ridges extending along a longitudinal direction of the base portion, closer together a plurality of projections of the pressing joints in the width direction in the elastic deformation step The base part is elastically deformed, and the low friction material part is welded and bonded so as to cover the portion where the convex stripes of the press-bonding part are formed in the welding and joining process, and the pressure-joining is performed by the elastic restoring force of the base part in the external force removing process. A pressing force may be applied to the low-friction material portion by expanding the interval between the protrusions of the portion in the width direction. If it does in this way, a pressing force can be made to act on the joining interface of a base part and a low friction material part with the convex strip of a press joining part, and the joint strength of a base part and a low friction material part can be raised. .

以下、本発明を実施するための最良の形態を4つの実施例1〜4を用いて説明する。   Hereinafter, the best mode for carrying out the present invention will be described using four Examples 1 to 4.

A first embodiment of the present invention will be described with reference to FIGS.
First, a schematic configuration of a sash type door 11 on the front side of an automobile will be described with reference to FIG. A window frame (sash) 12 is integrally attached to the sash type door 11 by welding or the like, and a long glass run channel 13 made of a polymer material is attached to the window frame 12 on the inner peripheral side of the window frame 12. The glass run channel 13 guides the window glass 14 to move up and down (slide movement).

窓枠12は、窓ガラス14の昇降移動方向とほぼ平行方向に延びる前側窓枠部15及び後側窓枠部16と、窓ガラス14の上端面に対向する上側窓枠部17とから構成され、上側窓枠部17には、フロントピラーの傾斜に対応して傾斜した傾斜部17aとルーフに対応してほぼ水平方向に延びる水平部17bとが形成されている。   The window frame 12 includes a front window frame portion 15 and a rear window frame portion 16 that extend in a direction substantially parallel to the up-and-down movement direction of the window glass 14, and an upper window frame portion 17 that faces the upper end surface of the window glass 14. The upper window frame portion 17 is formed with an inclined portion 17a inclined corresponding to the inclination of the front pillar and a horizontal portion 17b extending substantially in the horizontal direction corresponding to the roof.

一方、ガラスランチャンネル13は、前側窓枠部15に沿って装着される前側ガラスランチャンネル部19と、後側窓枠部16に沿って装着される後側ガラスランチャンネル部20と、上側窓枠部17(傾斜部17aから水平部17b)に沿って装着される上側ガラスランチャンネル部21と、上側ガラスランチャンネル部21と前側ガラスランチャンネル部19とを接合する前側コーナー部22と、上側ガラスランチャンネル部21と後側ガラスランチャンネル部20とを接合する後側コーナー部23とから構成されている。   On the other hand, the glass run channel 13 includes a front glass run channel portion 19 attached along the front window frame portion 15, a rear glass run channel portion 20 attached along the rear window frame portion 16, and an upper window. An upper glass run channel portion 21 mounted along the frame portion 17 (from the inclined portion 17a to the horizontal portion 17b), a front corner portion 22 that joins the upper glass run channel portion 21 and the front glass run channel portion 19, and an upper side The glass run channel portion 21 and the rear glass run channel portion 20 are constituted by a rear corner portion 23 for joining.

次に、窓枠12とガラスランチャンネル13の具体的な構成について説明する。但し、窓枠12の各窓枠部15〜17の要部は実質的に同じ構成であり、ガラスランチャンネル13の各ガラスランチャンネル部19〜21は実質的に同じ構成であるため、図2を用いて後側窓枠部16と後側ガラスランチャンネル部20の構成について説明し、前側及び上側窓枠部15,17と前側及び上側ガラスランチャンネル部19,21の構成については説明を省略する。   Next, specific configurations of the window frame 12 and the glass run channel 13 will be described. However, the main parts of the window frame portions 15 to 17 of the window frame 12 have substantially the same configuration, and the glass run channel portions 19 to 21 of the glass run channel 13 have substantially the same configuration. Are used to explain the configuration of the rear window frame portion 16 and the rear glass run channel portion 20, and the description of the configurations of the front and upper window frame portions 15 and 17 and the front and upper glass run channel portions 19 and 21 is omitted. To do.

図2に示すように、窓枠12(後側窓枠部16)は、例えば金属ストリップ材の折り曲げ加工により、内周側にガラスランチャンネル13を装着するための横断面略U字形状の溝状部24が長手方向に沿って形成されると共に、外周側にドアシール材(図示せず)を保持するためのドアシール材保持部25が長手方向に沿って形成され、溝状部24の幅方向略中央部で金属ストリップ材が複数枚折り重なった部分が長手方向に所定間隔でスポット溶接等により固着されている。溝状部24の車内側及び車外側の側壁には、それぞれガラスランチャンネル13を係止するための係止部26,27が形成されている。   As shown in FIG. 2, the window frame 12 (rear window frame portion 16) is a groove having a substantially U-shaped cross section for mounting the glass run channel 13 on the inner peripheral side, for example, by bending a metal strip material. And a door seal material holding portion 25 for holding a door seal material (not shown) on the outer peripheral side is formed along the longitudinal direction, and the width direction of the groove-like portion 24 is formed. A portion in which a plurality of metal strip materials are folded at a substantially central portion is fixed by spot welding or the like at a predetermined interval in the longitudinal direction. Locking portions 26 and 27 for locking the glass run channel 13 are formed on the inner side wall and the outer side wall of the groove-shaped portion 24, respectively.

一方、ガラスランチャンネル13(後側ガラスランチャンネル部20)のチャンネル本体28は、例えばEPDMを主体とするゴム等の弾性ポリマー材料の押出成形により、窓ガラス14の端面に対向する基底部29と、この基底部29の幅方向両端側からそれぞれ立ち上がるように延びる車内側の側壁部30及び車外側の側壁部31と、各側壁部30,31の先端側からそれぞれ基底部29の幅方向略中央側に向けて突出して折り返し状に形成された車内側のシールリップ32及び車外側のシールリップ33と、各側壁部30,31の先端側からそれぞれシールリップ32,33と反対側に向けて突出する車内側の遮蔽リップ34及び車外側の遮蔽リップ35と、各側壁部30,31の根元側からそれぞれ基底部29の幅方向外側に向けて突出する車内側の係止片36及び車外側の係止片37と、基底部29の外面から外周側に向けて突出する複数の外周側突条38とが一体に成形されている。   On the other hand, the channel main body 28 of the glass run channel 13 (rear glass run channel portion 20) is formed by, for example, a base portion 29 facing the end surface of the window glass 14 by extrusion molding of an elastic polymer material such as rubber mainly composed of EPDM. The vehicle interior side wall portion 30 and the vehicle exterior side wall portion 31 extending so as to rise from both ends in the width direction of the base portion 29, and the center portion in the width direction of the base portion 29 from the front end sides of the side wall portions 30 and 31, respectively. The inner side seal lip 32 and the outer side seal lip 33 projecting toward the side and projecting toward the opposite side of the seal lips 32, 33 from the front end side of the side walls 30, 31 respectively. The inner side lip 34 and the outer side lip 35 and the side walls 30, 31 from the base side toward the width direction outside of the base part 29. A locking piece 36 and the engaging piece 37 of the exterior of the vehicle interior side to output, and a plurality of outer circumferential side ribs 38 projecting toward the outer peripheral side from the outer surface of the base portion 29 is integrally formed.

窓枠12の溝状部24に沿ってガラスランチャンネル13を装着したときに、窓枠12の車内側の係止部26と車外側の係止部27に、それぞれガラスランチャンネル13の車内側の係止片36と車外側の係止片37が係止されることで、窓枠12の溝状部24にガラスランチャンネル13が抜け止め保持されるようになっている。また、ガラスランチャンネル13の車内側のシールリップ32と車外側のシールリップ33が、それぞれ窓ガラス14の表面に当接することで、窓ガラス14を保持すると共に窓枠12と窓ガラス14との間をシールするようになっている。   When the glass run channel 13 is mounted along the groove-like portion 24 of the window frame 12, the inner side of the glass run channel 13 is connected to the inner locking portion 26 and the outer locking portion 27 of the window frame 12, respectively. By locking the locking piece 36 and the locking piece 37 on the outside of the vehicle, the glass run channel 13 is held in the groove-like portion 24 of the window frame 12. Further, the seal lip 32 on the vehicle interior side and the seal lip 33 on the vehicle exterior side of the glass run channel 13 are in contact with the surface of the window glass 14, thereby holding the window glass 14 and the window frame 12 and the window glass 14. It is designed to seal the gap.

また、各シールリップ32,33の表面(つまり、窓ガラス14と接触する部分)には、それぞれ低摩擦材層39,40が形成されている。この低摩擦材層39,40は、窓ガラス14に対する摩擦係数がチャンネル本体28(基底部29等)よりも低い材料で形成され、窓ガラス14が移動するときにガラスランチャンネル13(シールリップ32,33)と窓ガラス14との間に生じる摩擦力(摺動抵抗)を小さくする役割を果たしている。   Further, low friction material layers 39 and 40 are formed on the surfaces of the seal lips 32 and 33 (that is, the portions in contact with the window glass 14), respectively. The low friction material layers 39 and 40 are formed of a material whose friction coefficient with respect to the window glass 14 is lower than that of the channel main body 28 (base portion 29 or the like), and the glass run channel 13 (seal lip 32) when the window glass 14 moves. , 33) and the window glass 14, the frictional force (sliding resistance) is reduced.

更に、各側壁部30,31の内面には、シールリップ32,33が側壁部30,31に付着することを防止するための付着防止層41,42が形成されている。この付着防止層41,42は、低摩擦材層39,40と同じ材料で形成されている。尚、シールリップ32,33の裏面に、付着防止層を形成しても良い。また、各側壁部30,31の内面とシールリップ32,33の裏面のうちの少なくとも一方を粗化する(凹凸形状にする)ことで、接触面積を小さくしてシールリップ32,33が側壁部30,31に付着することを防止するようにしても良い。これらの低摩擦材層39,40と付着防止層41,42はチャンネル本体28と共押出成形により熱融着されて強固に一体化されている。   Furthermore, adhesion preventing layers 41 and 42 for preventing the seal lips 32 and 33 from adhering to the side walls 30 and 31 are formed on the inner surfaces of the side walls 30 and 31. The adhesion preventing layers 41 and 42 are formed of the same material as the low friction material layers 39 and 40. An adhesion preventing layer may be formed on the back surfaces of the seal lips 32 and 33. In addition, by roughening at least one of the inner surfaces of the side wall portions 30 and 31 and the back surfaces of the seal lips 32 and 33 (into a concavo-convex shape), the contact area is reduced and the seal lips 32 and 33 are formed on the side wall portions. You may make it prevent adhering to 30,31. These low-friction material layers 39 and 40 and adhesion preventing layers 41 and 42 are firmly fused and integrated with the channel main body 28 by coextrusion molding.

また、基底部29の内面(つまり、窓ガラス14の端面と接触する部分)には、低摩擦材部43が基底部29の長手方向に沿って溶着接合されている。この低摩擦材部43は、窓ガラス14に対する摩擦係数がチャンネル本体28(基底部36等)よりも低い熱可塑性ポリマー材料の押出成形により形成され、窓ガラス14が移動するときにガラスランチャンネル13(基底部29)と窓ガラス14との間に生じる摩擦力(摺動抵抗)を小さくする役割を果たしている。   Further, the low friction material portion 43 is welded and joined along the longitudinal direction of the base portion 29 to the inner surface of the base portion 29 (that is, the portion in contact with the end surface of the window glass 14). The low friction material portion 43 is formed by extrusion molding of a thermoplastic polymer material having a friction coefficient with respect to the window glass 14 lower than that of the channel main body 28 (base portion 36 or the like), and the glass run channel 13 is moved when the window glass 14 moves. It plays the role of reducing the frictional force (sliding resistance) generated between the (base portion 29) and the window glass 14.

低摩擦材部43を形成する熱可塑性ポリマー材料は、チャンネル本体28を形成するゴムと熱溶着可能な熱可塑性ポリマー材料であり、それ自体がチャンネル本体28を形成するゴムよりも摩擦係数が低い熱可塑性ポリマー材料又はチャンネル本体28を形成するゴムよりも摩擦係数が低い材料を混練した熱可塑性ポリマー材料が用いられている。ここで、チャンネル本体28を形成するゴムよりも摩擦係数が低い熱可塑性ポリマー材料としては、例えば、PE樹脂(ポリエチレン樹脂)、PP樹脂(ポリプロピレン樹脂)、TPO(ポリオレフィン系熱可塑性エラストマー)、SBC(スチレン系熱可塑性エラストマー)、PVC樹脂(ポリ塩化ビニル樹脂)等を用いることができる。また、チャンネル本体28を形成するゴムよりも摩擦係数が低い材料を混練した熱可塑性ポリマー材料としては、例えば、高分子量PE樹脂、超高分子量PE樹脂、フッ素樹脂、シリコーン樹脂等の滑性材料を少なくとも1つを混練した熱可塑性ポリマー材料を用いることができる。   The thermoplastic polymer material that forms the low-friction material portion 43 is a thermoplastic polymer material that can be heat-welded with the rubber that forms the channel body 28, and itself has a lower coefficient of friction than the rubber that forms the channel body 28. A thermoplastic polymer material obtained by kneading a plastic polymer material or a material having a lower coefficient of friction than the rubber forming the channel body 28 is used. Here, as the thermoplastic polymer material having a lower coefficient of friction than the rubber forming the channel body 28, for example, PE resin (polyethylene resin), PP resin (polypropylene resin), TPO (polyolefin thermoplastic elastomer), SBC ( Styrenic thermoplastic elastomer), PVC resin (polyvinyl chloride resin), or the like can be used. Further, as the thermoplastic polymer material kneaded with a material having a lower friction coefficient than the rubber forming the channel body 28, for example, a lubricating material such as a high molecular weight PE resin, an ultra high molecular weight PE resin, a fluororesin, a silicone resin or the like is used. A thermoplastic polymer material in which at least one is kneaded can be used.

また、基底部29のうち低摩擦材部43との接合部分には、低摩擦材部43に押圧力を作用させるための押圧接合部44が設けられている。この押圧接合部44には、基底部29の長手方向に沿って延びる複数の凹条45が形成され、各凹条45間に凸条46が形成されている。この押圧接合部44の凹条45は、底部よりも入口部の幅寸法が狭くなる横断面略台形形状(あり溝形状)に形成されている。 In addition, a press bonding portion 44 for applying a pressing force to the low friction material portion 43 is provided at a portion of the base portion 29 where the low friction material portion 43 is bonded. This pressing junction 44, a plurality of concave Article 4 5 extending along a longitudinal direction of the base portion 29 is formed, the ridges 4 6 is formed between the concave 45. The concave strip 45 of the press bonding portion 44 is formed in a substantially trapezoidal shape (a dovetail groove shape) in which the width of the inlet portion is narrower than the bottom portion.

The rotation shafts 61 and 62 of the deformation rollers 57 and 58 are connected via gears 63 and 64, and the rotation shaft 62 of the lower deformation roller 58 is rotationally driven by a drive motor (not shown). The deformation rollers 57 and 58 are rotationally driven at the same peripheral speed in the direction in which the channel body continuous body S is sent out.

上側変形用ローラ57は、チャンネル本体連続体Sの基底部29を避けるように左右のローラ57a,57bに分割されて、チャンネル本体連続体Sの基底部29以外の部分を押さえるようになっている。一方のローラ57aの外周部には、チャンネル本体連続体Sの車内側の側壁部30及びシールリップ32を上方から押さえる押さえ部65と、基底部29の車内側端面を位置決めする位置決め部66とが形成され、他方のローラ57bの外周部には、チャンネル本体連続体Sの車外側の側壁部31及びシールリップ33を上方から押さえる押さえ部67と、基底部29の車外側端面を位置決めする位置決め部68とが形成されている。また、上側変形用ローラ57の左右のローラ57a,57b間のスペースに、押出成形機52の押出ダイ53の出口部が配置されている。   The upper deformation roller 57 is divided into left and right rollers 57a and 57b so as to avoid the base portion 29 of the channel body continuum S, and presses portions other than the base portion 29 of the channel body continuum S. . On the outer periphery of one roller 57a, there are a pressing portion 65 for pressing the side wall portion 30 and the seal lip 32 on the vehicle inner side of the channel body continuous body S from above, and a positioning portion 66 for positioning the vehicle inner end surface of the base portion 29.

一方、下側変形用ローラ58の外周部には、チャンネル本体連続体Sの基底部29を下方から押さえる押さえ部69と、車内側の側壁部30を下方から押さえる押さえ部70と、車外側の側壁部31を下方から押さえる押さえ部71とが形成されている。尚、チャンネル本体連続体Sを送り出す際の滑り止めとして、下側変形用ローラ58の押さえ部69等の表面に、ローレット加工等により凹凸模様を形成するようにしても良い。   On the other hand, on the outer peripheral portion of the lower deformation roller 58, a pressing portion 69 for pressing the base portion 29 of the channel body continuous body S from below, a pressing portion 70 for pressing the side wall portion 30 on the vehicle inner side from below, A pressing portion 71 that presses the side wall portion 31 from below is formed. In addition, as a slip stopper when the channel body continuous body S is sent out, an uneven pattern may be formed on the surface of the pressing portion 69 of the lower deformation roller 58 by knurling or the like.

これらの上側変形用ローラ57と下側変形用ローラ58との間に、チャンネル本体連続体Sが挟まれることで、チャンネル本体連続体Sの横断面形状が溶着接合用形状(各側壁部30,31を外側に広げると共に基底部29の内面側が凸面となるように基底部29を幅方向に湾曲させた形状)に弾性変形するようになっている。   The channel main body continuous body S is sandwiched between the upper deformation roller 57 and the lower deformation roller 58, so that the cross-sectional shape of the channel main body continuous body S becomes the shape for welding and joining (each side wall portion 30, 31 is expanded outward and elastically deformed into a shape in which the base portion 29 is curved in the width direction so that the inner surface side of the base portion 29 becomes a convex surface.

図4に示すように、予備変形用ローラ55,56は、上述した変形用ローラ57,58の上流側に配置されて、チャンネル本体連続体Sを送り出しながら、チャンネル本体連続体Sを所定の中間形状(図5に示すフリー状態時の形状と図6に示す溶着接合用形状との中間的な形状)に予備変形させるためのローラであり、上側予備変形用ローラ55と下側予備変形用ローラ56とが、チャンネル本体連続体Sを上下から挟むように配置されている。各予備変形用ローラ55,56の回転軸72,73がギヤ(図示せず)を介して連結され、変形用ローラ57,58と共通の駆動モータ又は専用の駆動モータ(図示せず)によって各予備変形用ローラ55,56がチャンネル本体連続体Sを送り出す方向に回転駆動されるようになっている。   As shown in FIG. 4, the preliminary deformation rollers 55 and 56 are arranged on the upstream side of the above-described deformation rollers 57 and 58, and the channel body continuum S is moved to a predetermined intermediate position while the channel body continuum S is sent out. 5 is a roller for preliminarily deforming into a shape (intermediate shape between the shape in a free state shown in FIG. 5 and the shape for welding and joining shown in FIG. 6), and is an upper predeformation roller 55 and a lower predeformation roller 56 are arranged so as to sandwich the channel body continuous body S from above and below. The rotation shafts 72 and 73 of the preliminary deformation rollers 55 and 56 are connected via gears (not shown), and are respectively connected to the deformation rollers 57 and 58 by a common drive motor or a dedicated drive motor (not shown). The preliminary deformation rollers 55 and 56 are rotationally driven in the direction in which the channel body continuous body S is sent out.

また、圧着用ローラ59,60は、変形用ローラ57,58の下流側に配置されて、チャンネル本体連続体Sを送り出しながら、チャンネル本体連続体Sを溶着接合用形状に弾性変形させた状態で基底部29に低摩擦材部43を圧着させるさせるためのローラであり、上側圧着用ローラ59と下側圧着用ローラ60とが、チャンネル本体連続体Sを上下から挟むように配置されている。各圧着用ローラ59,60の回転軸74,75がギヤ(図示せず)を介して連結され、変形用ローラ57,58と共通の駆動モータ又は専用の駆動モータ(図示せず)によって各圧着用ローラ59,60がチャンネル本体連続体Sを送り出す方向に回転駆動されるようになっている。   Further, the pressure-bonding rollers 59 and 60 are arranged on the downstream side of the deformation rollers 57 and 58, and the channel main body continuous body S is elastically deformed into the shape for welding and joining while the channel main body continuous body S is sent out. It is a roller for causing the low friction material portion 43 to be crimped to the base portion 29, and an upper crimping roller 59 and a lower crimping roller 60 are disposed so as to sandwich the channel body continuous body S from above and below. The rotation shafts 74 and 75 of the pressure-bonding rollers 59 and 60 are connected via gears (not shown), and the pressure-bonding rollers 57 and 58 and the pressure-reducing rollers 57 and 58 are each pressure-bonded by a common drive motor or a dedicated drive motor (not shown). The rollers 59 and 60 are rotationally driven in the direction of feeding out the channel body continuous body S.

低摩擦材部成形工程では、押出成形機52に低摩擦材部43を形成する熱可塑性ポリマー材料を供給して、押出成形機52の押出ダイ53で低摩擦材部43を連続的に押出成形する。その際、図6に示すように、低摩擦材部43のうち基底部29との接合部分に、押圧接合部44の凹条45に対応した凸条47を形成することで、後述する溶着接合工程で、低摩擦材部43の接合面を基底部29の接合面(押圧接合部44)に良好に接合させることができるようにする。   In the low friction material part forming step, the thermoplastic polymer material for forming the low friction material part 43 is supplied to the extruder 52, and the low friction material part 43 is continuously extruded by the extrusion die 53 of the extruder 52. To do. At this time, as shown in FIG. 6, a protrusion 47 corresponding to the recess 45 of the press bonding portion 44 is formed at the bonding portion of the low friction material portion 43 with the base portion 29, thereby performing welding bonding described later. In the process, the bonding surface of the low friction material portion 43 can be favorably bonded to the bonding surface (press bonding portion 44) of the base portion 29.

一方、弾性変形工程では、溶着接合機54の予備変形ローラ55,56で、チャンネル本体連続体Sを送り出しながら、基底部29及び側壁部30,31に外力を加えてチャンネル本体連続体Sを中間形状に予備変形させた後、図6に示すように、溶着接合機54の変形用ローラ57,58で、チャンネル本体連続体Sを送り出しながら、基底部29及び各側壁部30,31に外力を加えてチャンネル本体連続体Sを溶着接合用形状に弾性変形させることで、押圧接合部44の凹条45を幅方向に拡開させる。その際、押圧接合部44の凹条45は、入口部の幅寸法が底部の幅寸法とほぼ同じか又はそれよりも広くなる程度まで拡開させるようにすると良い。   On the other hand, in the elastic deformation process, while the channel body continuum S is sent out by the preliminary deformation rollers 55 and 56 of the welding joint machine 54, an external force is applied to the base portion 29 and the side wall portions 30 and 31, so that the channel body continuum S is intermediate. After preliminarily deforming into the shape, as shown in FIG. 6, external force is applied to the base portion 29 and the side wall portions 30, 31 while feeding the channel body continuous body S with the deformation rollers 57, 58 of the welding joint machine 54. In addition, the channel body continuous body S is elastically deformed into the shape for welding and bonding, so that the concave strip 45 of the press bonding portion 44 is expanded in the width direction. At this time, the concave strip 45 of the press bonding portion 44 is preferably expanded so that the width dimension of the inlet portion is substantially the same as or wider than the width dimension of the bottom portion.

更に、溶着接合工程では、変形用ローラ57,58でチャンネル本体連続体Sを溶着接合用形状に弾性変形させた状態で、押出成形機52の押出ダイ53から供給される低摩擦材部43を基底部29に積層して、押圧接合部44の凹条45に低摩擦材部43の凸条47を入り込ませる。ここで、本実施例1のように、チャンネル本体成形工程後に弾性変形工程と溶着接合工程を連続的に実行する場合には、チャンネル本体連続体Sの成形時の熱(未加硫のチャンネル本体連続体Sを加硫させた際の熱)が放熱されて所定の温度を下回らないうちに溶着接合工程に進むことができるため、チャンネル本体連続体Sの成形時の熱を利用して低摩擦材部43の接合面の急激な温度低下に伴う固化を防いで軟化状態又は溶融状態を良好に維持させることができる。   Further, in the welding and bonding step, the low friction material portion 43 supplied from the extrusion die 53 of the extrusion molding machine 52 in a state where the channel body continuous body S is elastically deformed into the shape for welding and bonding by the deformation rollers 57 and 58. The ridges 47 of the low friction material portion 43 are inserted into the ridges 45 of the press bonding portion 44 by being laminated on the base portion 29. Here, as in the first embodiment, when the elastic deformation step and the welding and joining step are continuously performed after the channel body forming step, heat at the time of forming the channel body continuous body S (unvulcanized channel body). (The heat generated when the continuum S is vulcanized) is dissipated and can proceed to the welding and joining process before the temperature falls below a predetermined temperature. It is possible to prevent the solidification accompanying the rapid temperature drop of the joint surface of the material part 43 and to maintain the softened state or the molten state well.

この後、圧着用ローラ59,60で、チャンネル本体連続体Sを送り出しながら、基底部29及び側壁部30,31に外力を加えてチャンネル本体連続体Sを溶着接合用形状に弾性変形させた状態で、低摩擦材部43に上方から圧力を加えて基底部29に低摩擦材部43を圧着させることで、押圧接合部44の凹条45を低摩擦材部43の凸条47で埋めるように低摩擦材部43を溶着接合する。   Thereafter, the channel body continuum S is elastically deformed into the shape for welding and joining by applying external force to the base portion 29 and the side wall portions 30 and 31 while feeding the channel body continuum S by the pressure rollers 59 and 60. Then, pressure is applied to the low friction material portion 43 from above and the low friction material portion 43 is pressure-bonded to the base portion 29, so that the concave stripe 45 of the press bonding portion 44 is filled with the convex stripe 47 of the low friction material portion 43. The low friction material portion 43 is welded and joined.

この溶着接合工程の実行後に、チャンネル本体連続体Sが圧着用ローラ59,60から送り出されることで、圧着用ローラ59,60によって基底部29及び側壁部30,31に付加されていた外力が除去される外力除去工程となる。この外力除去工程では、図7に示すように、圧着用ローラ59,60によって基底部29及び側壁部30,31に付加されていた外力が除去されるため、チャンネル本体連続体Sが弾性復元力により元の形状(外力が加わっていないフリー状態時の形状)に戻る。その際、基底部29の弾性復元力によって押圧接合部44の凹条45が幅方向に縮小することで、押圧接合部44の凹条45で低摩擦材部43の凸条47に幅方向の押圧力が作用すると共に、押圧接合部44の凸条46が低摩擦材部43の凸条47,47間に食い込むようになっている。   After execution of this welding and joining step, the channel body continuum S is sent out from the pressure-bonding rollers 59, 60, so that the external force applied to the base portion 29 and the side wall portions 30, 31 by the pressure-bonding rollers 59, 60 is removed. It becomes an external force removal process. In this external force removing step, as shown in FIG. 7, the external force applied to the base portion 29 and the side wall portions 30 and 31 is removed by the pressure-bonding rollers 59 and 60, so that the channel body continuum S has an elastic restoring force. To return to the original shape (the shape in a free state where no external force is applied). At that time, the concave strip 45 of the press bonding portion 44 is reduced in the width direction by the elastic restoring force of the base portion 29, so that the convex strip 47 of the low friction material portion 43 is extended in the width direction by the concave strip 45 of the press bonding portion 44. A pressing force is applied, and the ridge 46 of the pressing joint portion 44 bites between the ridges 47 of the low friction material portion 43.

このようにして、長尺状のガラスランチャンネル連続体Tを成形した後、図3に示すように、冷却工程に進み、ガラスランチャンネル連続体Tを冷却槽76内に通し、この冷却槽76内で低摩擦材部43を冷却して固化させる。この後、切断工程に進み、引取機77でガラスランチャンネル連続体Tを引取りながら、ガラスランチャンネル連続体Tを切断機78によって所定の長さ寸法(前側ガラスランチャンネル部19の長さ寸法又は後側ガラスランチャンネル部20の長さ寸法又は上側ガラスランチャンネル部21の長さ寸法)に切断して、前側ガラスランチャンネル部19又は後側ガラスランチャンネル部20又は上側ガラスランチャンネル部21を形成する。   After forming the long glass run channel continuous body T in this way, as shown in FIG. 3, the process proceeds to a cooling step, and the glass run channel continuous body T is passed through the cooling tank 76, and this cooling tank 76 is passed. The low friction material portion 43 is cooled and solidified. Thereafter, the process proceeds to a cutting step, and the glass run channel continuum T is pulled by the taker 77 while the glass run channel continuum T is cut to a predetermined length by the cutter 78 (the length of the front glass run channel portion 19). Or the length dimension of the rear glass run channel section 20 or the length dimension of the upper glass run channel section 21), and the front glass run channel section 19 or the rear glass run channel section 20 or the upper glass run channel section 21. Form.

この後、接合工程に進み、前側コーナー部22を成形する射出成形型(図示せず)に、上側ガラスランチャンネル部21の前端部と前側ガラスランチャンネル部19の上端部を所定角度で交差させてセットした状態で、該射出成形型内に弾性ポリマー材料を射出して前側コーナー部22を形成することで、上側ガラスランチャンネル部21と前側ガラスランチャンネル部19とを前側コーナー部22を介して接合する。更に、後側コーナー部23を成形する射出成形型(図示せず)に、上側ガラスランチャンネル部21の後端部と後側ガラスランチャンネル部20の上端部を所定角度で交差させてセットした状態で、該射出成形型内に弾性ポリマー材料を射出して後側コーナー部23を形成することで、上側ガラスランチャンネル部21と後側ガラスランチャンネル部20とを後側コーナー部23を介して接合する。これによりガラスランチャンネル13の製造が完了する。   Then, it progresses to a joining process, and the front end part of the upper glass run channel part 21 and the upper end part of the front glass run channel part 19 are crossed at a predetermined angle in an injection mold (not shown) for forming the front corner part 22. In this state, an elastic polymer material is injected into the injection mold to form the front corner portion 22, so that the upper glass run channel portion 21 and the front glass run channel portion 19 are connected via the front corner portion 22. And join. Furthermore, the rear end portion of the upper glass run channel portion 21 and the upper end portion of the rear glass run channel portion 20 are set to intersect with each other at a predetermined angle in an injection mold (not shown) for forming the rear corner portion 23. In this state, an elastic polymer material is injected into the injection mold to form the rear corner portion 23, so that the upper glass run channel portion 21 and the rear glass run channel portion 20 are connected via the rear corner portion 23. And join. Thereby, the manufacture of the glass run channel 13 is completed.

以上説明した本実施例1では、ガラスランチャンネル13の基底部29のうち低摩擦材部43との接合部分に押圧接合部44を設け、外力を加えて基底部29を弾性変形させた状態で該基底部29に低摩擦材部43を溶着接合した後に外力を解放して基底部29の弾性復元力によって押圧接合部44の凹条45で低摩擦材部43に押圧力を作用させるようにしたので、押圧接合部44の凹条45で基底部29と低摩擦材部43との接合界面に押圧力を作用させることができ、基底部29(ランチャンネル本体28)を形成する材料と低摩擦材部43を形成する材料との相溶性があまり高くなくても、基底部29と低摩擦材部43との接合強度を高めることができる。これにより、基底部29と低摩擦材部43との接合強度を十分に確保することができると共に、低摩擦材部43を形成する材料の選択の自由度を広げることができ、互いに相溶性が高い材料という制約を受けることなく、より高い滑り性、コスト、成形性等をも考慮した幅広い材料選択を行うことができる。   In the first embodiment described above, a pressing joint 44 is provided at a joint portion of the base portion 29 of the glass run channel 13 with the low friction material portion 43, and the base portion 29 is elastically deformed by applying an external force. After the low friction material portion 43 is welded and joined to the base portion 29, the external force is released, and a pressing force is applied to the low friction material portion 43 by the recess 45 of the press joint portion 44 by the elastic restoring force of the base portion 29. As a result, it is possible to apply a pressing force to the bonding interface between the base portion 29 and the low friction material portion 43 by the concave strip 45 of the press bonding portion 44, and the material for forming the base portion 29 (run channel body 28) is low. Even if the compatibility with the material forming the friction material portion 43 is not so high, the bonding strength between the base portion 29 and the low friction material portion 43 can be increased. As a result, the bonding strength between the base portion 29 and the low friction material portion 43 can be sufficiently secured, and the degree of freedom of selection of the material for forming the low friction material portion 43 can be expanded, and the compatibility is mutually improved. A wide variety of materials can be selected in consideration of higher slipperiness, cost, moldability, etc. without being restricted by high materials.

更に、本実施例1では、押圧接合部44に、基底部29の長手方向に沿って延びる複数の凹条45を形成するようにしたので、押圧接合部44に形成した複数の凹条45で基底部29と低摩擦材部43との接合界面に押圧力を作用させることができ、基底部29と低摩擦材部43との接合強度を確実に高めることができる。   Furthermore, in the first embodiment, since the plurality of concave strips 45 extending along the longitudinal direction of the base portion 29 are formed in the press joint portion 44, the plurality of concave strips 45 formed in the press joint portion 44 are used. A pressing force can be applied to the bonding interface between the base portion 29 and the low friction material portion 43, and the bonding strength between the base portion 29 and the low friction material portion 43 can be reliably increased.

しかも、本実施例1では、押圧接合部44の凹条45に低摩擦材部43の凸条47が入り込むと共に、押圧接合部44の凸条46が低摩擦材部43の凸条47間に食い込むようにしたので、押圧接合部44の凹条45に入り込んだ低摩擦材部43のアンカー作用及び低摩擦材部43に食い込んだ押圧接合部44の凸条46のアンカー作用によっても基底部29と低摩擦材部43との接合強度を高めることができる。   Moreover, in the first embodiment, the protrusions 47 of the low friction material portion 43 enter the recesses 45 of the press bonding portion 44, and the protrusions 46 of the press bonding portion 44 are between the protrusions 47 of the low friction material portion 43. Since it bites in, the base portion 29 is also caused by the anchor action of the low friction material portion 43 that has entered the recess 45 of the press bonding portion 44 and the anchor action of the protrusion 46 of the press bonding portion 44 that has bitten into the low friction material portion 43. And the bonding strength between the low friction material portion 43 can be increased.

更に、本実施例1では、押圧接合部44の凹条45を、底部よりも入口部の幅寸法が狭くなる横断面略台形形状に形成したので、押圧接合部44の凹条45に入り込んだ低摩擦材部43を凹条45から抜けにくくすることができ、基底部29と低摩擦材部43との接合強度を更に高めることができる。   Furthermore, in the first embodiment, the concave strip 45 of the press bonding portion 44 is formed in a substantially trapezoidal cross-sectional shape in which the width dimension of the inlet portion is narrower than the bottom portion. It is possible to make it difficult for the low friction material portion 43 to come out of the recess 45, and to further increase the bonding strength between the base portion 29 and the low friction material portion 43.

また、本実施例1では、低摩擦材部成形工程で、低摩擦材部43のうち基底部29との接合部分に、押圧接合部44の凹条45に対応した凸条47を形成するようにしたので、溶着接合工程で、押圧接合部44の凹条45に低摩擦材部43の凸条47を確実に入り込ませて、低摩擦材部43の接合面を基底部29の接合面(押圧接合部44)に確実に密着させることができる。   Further, in the first embodiment, in the low friction material portion molding step, the protrusion 47 corresponding to the recess 45 of the press bonding portion 44 is formed in the bonding portion of the low friction material portion 43 with the base portion 29. Therefore, in the welding and joining step, the protrusion 47 of the low friction material portion 43 is surely inserted into the recess 45 of the press bonding portion 44, and the joining surface of the low friction material portion 43 is changed to the joining surface ( It is possible to ensure close contact with the press bonding portion 44).

ところで、チャンネル本体連続体Sが移動方向(長手方向)に引張力を受けて延びた状態で低摩擦材部43を溶着接合すると、チャンネル本体連続体Sが縮んで元の形状に戻ったときに溶着接合不良が発生する可能性がある。   By the way, when the low friction material part 43 is welded and joined in a state in which the channel body continuum S is stretched in the moving direction (longitudinal direction), the channel body continuum S contracts and returns to its original shape. There is a possibility of poor weld joints.

そこで、本実施例1では、弾性変形工程で、溶着接合機54の予備変形ローラ55,56及び変形用ローラ57,58ローラで、チャンネル本体連続体Sを送り出しながら基底部29を弾性変形させるようにしたので、チャンネル本体連続体S(基底部29)が移動方向に引張力を受けて延びることを防止しながらチャンネル本体連続体S(基底部29)を溶着接合用形状に弾性変形させた状態で溶着接合工程に進むことができ、低摩擦材部43の溶着接合不良を防止することができる。   Therefore, in the first embodiment, in the elastic deformation step, the base portion 29 is elastically deformed while the channel body continuous body S is being fed by the preliminary deformation rollers 55 and 56 and the deformation rollers 57 and 58 of the welding and bonding machine 54. As a result, the channel body continuum S (base portion 29) is elastically deformed into the shape for welding and joining while preventing the channel body continuum S (base portion 29) from being extended by receiving a tensile force in the moving direction. Thus, it is possible to proceed to the welding and joining step, and it is possible to prevent the welding failure of the low friction material portion 43.

しかも、本実施例1では、弾性変形工程で、基底部29と各側壁部30,31に外力を加えてチャンネル本体連続体Sを溶着接合用形状に弾性変形させるようにしたので、チャンネル本体連続体S(基底部29)を確実に溶着接合用形状に弾性変形させることができる。   Moreover, in the first embodiment, in the elastic deformation process, the channel body continuous body S is elastically deformed into the shape for welding and joining by applying an external force to the base portion 29 and the side wall portions 30 and 31. The body S (base portion 29) can be reliably elastically deformed into the shape for welding and bonding.

また、本実施例1では、前側、後側、上側の各ガラスランチャンネル部を同一断面のガラスランチャンネル連続体Tから形成してコーナー部を介して接合したが、例えば、前側、及び後側ガラスランチャンネル部を同一断面のガラスランチャンネル連続体Tから形成して、上側ガラスランチャンネル部を異なる断面のガラスランチャンネル連続体から形成し、これらをコーナー部を介して接合することも可能である。   In the first embodiment, the glass run channel portions on the front side, the rear side, and the upper side are formed from the glass run channel continuous body T having the same cross section and joined via the corner portion. For example, the front side and the rear side It is also possible to form a glass run channel part from a glass run channel continuous body T having the same cross section, and form an upper glass run channel part from a glass run channel continuous body having a different cross section, and join these via a corner part. is there.

以下、本発明の実施例2〜4を図8乃至図11に基づいて説明する。但し、前記実施例1と実質的に同一部分には同一符号を付して説明を簡略化し、主として前記実施例1と異なる部分について説明する。   Embodiments 2 to 4 of the present invention will be described below with reference to FIGS. However, substantially the same parts as those in the first embodiment are denoted by the same reference numerals, and the description will be simplified. The parts different from the first embodiment will be mainly described.

In this state (a state in which the base portion 29 is curved in the width direction so that the inner surface side of the base portion 29 becomes a convex surface), the low friction material portion 80 is laminated on the base portion 29 and the wide groove 81 of the press bonding portion 79 is stacked. The low-friction material portion 80 is welded and joined so that the lower portion of the low-friction material portion 80 is filled. Thereafter, the external force applied to the base portion 29 and the side wall portions 30 and 31 is removed, and the wide concave stripes 81 that have spread in the width direction of the press bonding portion 79 are reduced by the elastic restoring force of the base portion 29. In addition, a pressing force is applied across the entire lower portion of the low friction material portion 80 with the wide concave strip 81 of the press bonding portion 79, and the locking protrusions 82 of the press bonding portion 79 are engaged with the locked portion of the low friction material portion 80. 83 to be locked.

In a state (a state in which the base portion 29 is curved in the width direction so that the inner surface side of the base portion 29 becomes a convex surface), the low friction material portion 86 is laminated on the base portion 29 to reduce the concave stripe 85 of the press bonding portion 84. The low friction material portion 86 is welded and joined so as to be filled with the ridges 87 of the friction material portion 86. Thereafter, the external force applied to the base portion 29 and the side wall portions 30 and 31 is removed, and the concave strip 85 of the press joint portion 84 is reduced in the width direction by the elastic restoring force of the base portion 29, whereby the press joint portion A pressing force is applied to the ridge 87 of the low friction material portion 86 by the 84 ridges 85.

In a state (a state in which the base portion 29 is curved in the width direction so that the inner surface side of the base portion 29 is concave), the low friction material portion 91 is laminated on the base portion 29 to form the wide protrusions 89 of the press bonding portion 88. The low friction material portion 91 is welded and joined so as to be covered with the low friction material portion 91. Thereafter, the external force applied to the base portion 29 and the side wall portions 30 and 31 is removed, and the wide protrusions 89 of the press joint portion 88 are expanded in the width direction by the elastic restoring force of the base portion 29, thereby The wide protrusions 89 of the portion 88 cause a pressing force to act on both ends of the low friction material portion 91, and the locking protrusions 89 of the pressing joint portion 88 are locked to the locked portion 92 of the low friction material portion 91.
