Description

本発明は、スライドレールに連結された家具等の引出し部、陳列棚、レンジグリル等の移動側部材を、引出し状態（スライド全開状態）から収納位置（最終収納位置）まで完全に移動させなくても、所定位置まで移動されると、後は自動的に家具本体等の固定側部材に引き込まれ、さらに、移動側部材を固定側部材に勢いよく移動させた時に生じる移動側部材の跳ね返りの防止、あるいは、運搬時、地震時等、固定側部材からの移動側部材の不用意な飛び出しを防止する引込み機能を有するスライドレールに関するものである。 The present invention does not completely move the drawer portion of furniture or the like connected to the slide rail, the display shelf, the moving side member such as the range grill, from the drawer state (slide fully open state) to the storage position (final storage position). However, when it is moved to a predetermined position, it is automatically pulled into the fixed side member such as the furniture body, and further, the movement side member is prevented from bouncing back when the moving side member is vigorously moved to the fixed side member. Alternatively, the present invention relates to a slide rail having a retracting function for preventing the moving side member from inadvertently popping out from the fixed side member during transportation, an earthquake, or the like.

家具本体等の固定側部材に引出し部等の移動側部材を収納する時、移動側部材を勢い良く収納すると、収納時の跳ね返りによって、移動側部材が完全に収納されなかったり、移動側部材が最初から完全に収納されていなかったりする場合があり、家具の運搬時や地震時に、引出し等が固定側部材から飛び出した勢いで、家具等を運搬中に落下させたり、あるいは転倒することで数々の不都合が生じる原因となっていた。
この問題を解決するため、移動側部材が所定位置まで収納されると、後は自動的に家具本体等の固定側部材に引込む、引込み機能を有するスライドレールが幾種類か提供されている。 When storing a moving side member such as a drawer in a fixed side member such as a furniture body, if the moving side member is stored vigorously, the moving side member may not be completely stored or the moving side member may not be completely stored due to the bounce during storage. It may not be completely stored from the beginning, and when the furniture is being transported or during an earthquake, the drawers, etc. may pop out from the fixed side member, causing the furniture to be dropped or overturned during transportation. Was the cause of the inconvenience.
In order to solve this problem, several types of slide rails having a retracting function are provided, which automatically retract the moving side member to a fixed side member such as a furniture main body when the moving side member is stored to a predetermined position.

その一つとして、移動側レールに引込み部材を設け、引込み部材に対応して固定側レールに引込み案内路を設け、引込み部材は、移動側レールが固定側レールに対して最終所定位置に近づいたとき、引込み案内路に弾性的に圧接する圧接機構を有し、引込み案内路は、固定側レールの折曲縁と一体に形成され、圧接機構の圧接力を、移動側部材を固定側部材に対し最終所定位置となす方向への引込み力に変化させるものである。
そして、圧接機構を、回動する回転腕と、固定側レールの折曲縁、引込み案内路に沿って転動する圧接子と、回転腕に引込み案内路側への付勢力を与えるバネで構成したものが本件特許出願人により提供されている（特許文献１）。 As one of them, a pull-in member is provided on the moving-side rail, and a pull-in guide path is provided on the fixed-side rail corresponding to the pull-in member. When, it has a pressure contact mechanism that elastically presses against the pull-in guide path, and the lead-in guide path is formed integrally with the bent edge of the fixed side rail, and the pressure contact force of the pressure contact mechanism is applied to the moving side member to the fixed side member. On the other hand, it changes the pulling force in the direction of the final predetermined position.
The pressure welding mechanism is composed of a rotating rotating arm, a bent edge of the fixed side rail, a pressure welding element that rolls along the pull-in guide path, and a spring that gives the rotating arm an urging force to the pull-in guide path side. Is provided by the Patent Applicant (Patent Document 1).

特許文献１で提供されている引込み部材では、回転腕に引込み案内路側への付勢力を与えるバネとして、コイルバネが使用され、さらに、移動側レールに取り付けられる連結用支持部材から、移動側レール方向に回転軸が突出し、該回転軸にコイルバネが巻き付けられ、そして、コイルバネの移動側レール端部に回転腕が配置される構成となっている。
しかしながら、このような構成では、回転腕が、スライドレールの厚み方向で、移動側レールと固定側レールの中間位置付近に配置されることになり、連結用支持部材と回転腕の距離が近くなってしまうため、連結用支持部材と回転腕に設置されるコイルバネの巻き数が必然的に少なくなり、コイルバネの耐久性を上げることが難しかった。 In the retracting member provided in Patent Document 1, a coil spring is used as a spring that gives an urging force to the retracting guide path side to the rotating arm, and further, from the connecting support member attached to the moving side rail, the moving side rail direction. A rotary shaft protrudes from the shaft, a coil spring is wound around the rotary shaft, and a rotary arm is arranged at the end of the moving side rail of the coil spring.
However, in such a configuration, the rotating arm is arranged near the intermediate position between the moving side rail and the fixed side rail in the thickness direction of the slide rail, and the distance between the connecting support member and the rotating arm becomes short. Therefore, the number of turns of the coil spring installed on the connecting support member and the rotating arm is inevitably reduced, and it is difficult to improve the durability of the coil spring.

Arranged at a position offset from the inner surface side to the fixed side rail side with reference to the inner surface side of the substrate between the upper and lower bent edges, and the main rotation shaft protrudes from the shaft portion protruding portion toward the moving side rail side. It was configured to be.

上記課題を解決する為、本発明が第３の手段として構成したところは、上記第１の手段としての構成に加え、軸部突出部を、スライドレールの正面視において、固定側レールの基板よりも、移動側レールの基板に近くなる位置に配置し、主回転軸を、軸部突出部から固定側レール側に向かって突出する構成とした。 In order to solve the above problems, the present invention is configured as the third means, in addition to the configuration as the first means, the shaft portion protruding portion is seen from the substrate of the fixed side rail in the front view of the slide rail. Also, it is arranged at a position close to the board of the moving side rail, and the main rotating shaft is configured to protrude from the shaft portion protruding portion toward the fixed side rail side.

Since it is arranged in, the main rotation shaft can be extended to the fixed side rail substrate side, the distance between the shaft protrusion and the rotation arm can be set wide, and the number of turns of the coil spring can be increased. Therefore, the durability of the coil spring can be improved.

本発明の第４の手段として構成したところによると、第１の手段として構成したところの効果に加え、軸部突出部を、固定側レール側にオフセットされた位置に配置される主軸部突出部と、固定側レールの基板よりも、移動側レールの基板に近くなる位置に配置される副軸部突出部とで構成し、主回転軸の一方端を主軸部突出部に連結し、他方端を副軸部突出部に連結しているから、主回転軸は両端で固定され安定する。そのため、回転腕を安定して枢止できるので、コイルバネの強さを強くしても、主回転軸が無用に捩じれることなく、コイルバネの巻き数を増やして耐久性を向上させることができる。 According to the configuration as the fourth means of the present invention, in addition to the effect of the configuration as the first means, the spindle protrusion is arranged at a position offset to the fixed side rail side. And an auxiliary shaft protruding portion arranged at a position closer to the substrate of the moving side rail than the substrate of the fixed side rail, one end of the main rotation shaft is connected to the main shaft portion protruding portion, and the other end is connected. Is connected to the protrusion of the sub-shaft, so the main rotation shaft is fixed and stable at both ends. Therefore, since the rotating arm can be stably pivoted, even if the strength of the coil spring is increased, the main rotating shaft is not unnecessarily twisted, and the number of turns of the coil spring can be increased to improve durability.

圧接子５６は、固定側レール２の上折曲縁２１（引込み案内路９）のボール摺動溝２０に沿う外形を有する回転ローラー部５６１と、回転ローラー部５６１の一方端側の平面部から突出するように、円柱状の軸受部５６２が形成され、軸受部５６２と回転ローラー部５６１を左右方向に貫通する副回転軸５５の副軸部５５１よりわずかに径の大きい貫通孔５６３が設けられ、合成樹脂で一体的で形成されるものである。 The pressure bearing 56 is formed from a rotary roller portion 561 having an outer shape along the ball sliding groove 20 of the upper bending edge 21 (pull-in guide path 9) of the fixed side rail 2 and a flat surface portion on one end side of the rotary roller portion 561. A columnar bearing portion 562 is formed so as to project, and a through hole 563 having a diameter slightly larger than that of the sub-shaft portion 551 of the sub-rotary shaft 55 that penetrates the bearing portion 562 and the rotary roller portion 561 in the left-right direction is provided. , It is integrally formed of synthetic resin.

以上の引き込み部材５の構成部材は、次のように組み合わせられる。
まず、圧接子５６の貫通孔５６３の回転ローラー部５６１側から、副回転軸５５を固定軸部５５３側から挿入する。挿入すると、貫通孔５６３から固定軸部５５３が飛び出した状態となる。そして、該固定軸部５５３を、回転腕５３の副回転軸保持孔５３４に挿入し、固定軸部５５３の先端をかしめると、副回転軸５５は圧接子５６を、副回転軸５５を軸として回転自在に保持しながら、回転腕５３に固定される。 The constituent members of the pull-in member 5 described above are combined as follows.
First, the auxiliary rotary shaft 55 is inserted from the rotary roller portion 561 side of the through hole 563 of the pressure welder 56 from the fixed shaft portion 553 side. When inserted, the fixed shaft portion 553 protrudes from the through hole 563. Then, when the fixed shaft portion 553 is inserted into the sub-rotating shaft holding hole 534 of the rotating arm 53 and the tip of the fixed shaft portion 553 is crimped, the sub-rotating shaft 55 shafts the pressure welder 56 and the sub-rotating shaft 55. It is fixed to the rotating arm 53 while being rotatably held as.

次に、コイルバネ５４を、コイル部５４１の第２係止部５４３側から、回転腕５３軸受部５３２に挿入する。そして、図９に示すように、第２係止部５４３を係止突片５３５の内側に係止させる。
そして、回転腕５３の貫通孔５３３に、軸受部５３２の対向側から、主回転軸５２を固定軸部５２３側から挿入する。
挿入すると、貫通孔５３３から固定軸部５２３が飛び出した状態となる。そして、該固定軸部５２３を、連結用支持部材５０の主回転軸保持孔５１１に連結部５０１側から挿入し、固定軸部５２３の先端をかしめると、主回転軸５２は回転腕５３を、主回転軸５２を軸として回転自在に保持しながら、軸部突出部５１に固定される。
この時、コイルバネ５４の第１係止部５４３を、連結用支持部材５０のバネ保持部５０４に係止させる。 Next, the coil spring 54 is inserted into the rotary arm 53 bearing portion 532 from the second locking portion 543 side of the coil portion 541. Then, as shown in FIG. 9, the second locking portion 543 is locked inside the locking projecting piece 535.
Then, the main rotating shaft 52 is inserted into the through hole 533 of the rotating arm 53 from the opposite side of the bearing portion 532 and from the fixed shaft portion 523 side.
When inserted, the fixed shaft portion 523 protrudes from the through hole 533. Then, when the fixed shaft portion 523 is inserted into the main rotating shaft holding hole 511 of the connecting support member 50 from the connecting portion 501 side and the tip of the fixed shaft portion 523 is crimped, the main rotating shaft 52 causes the rotating arm 53. , While rotatably holding the main rotating shaft 52 as an axis, it is fixed to the shaft portion protruding portion 51.
At this time, the first locking portion 543 of the coil spring 54 is locked to the spring holding portion 504 of the connecting support member 50.

この状態で、コイルバネ５４は、回転腕５３を連結部５０１側に引き込むように付勢している。したがって、回転腕５３を、圧接子５６側が連結部５０１から離れる方向に回転させた後、離すと、コイルバネ５４の付勢力によって、回転腕５３を連結部５０１側に回転して戻ってくることになる。 In this state, the coil spring 54 is urged to pull the rotating arm 53 toward the connecting portion 501 side. Therefore, when the rotary arm 53 is rotated in a direction in which the pressure welder 56 side is separated from the connecting portion 501 and then released, the rotating arm 53 is rotated back to the connecting portion 501 side by the urging force of the coil spring 54. Become.

このように組み立てられた引き込み部材５を、スライドレール１００の移動側レール１に取り付ける方法を説明する。
スライドレール１００を最収縮させた状態で、移動側レール基板１２の係合孔１２１の固定側レール２の対向側の面から、連結部５０１の係合片５０１ａを差し込み、連結部５０１の平面部を移動側レール基板１２に密着させ、回転ローラー５６１の外周凸面を、固定側レール２に設けられた引き込み案内路７に沿わし、そして、固定穴５０１ｂと、螺孔１２２を使って、ネジにて固定することにより、引き込み部材５は、スライドレール１００に取り付けられる。 A method of attaching the retracting member 5 thus assembled to the moving side rail 1 of the slide rail 100 will be described.
With the slide rail 100 fully contracted, the engaging piece 501a of the connecting portion 501 is inserted from the opposite surface of the fixed side rail 2 of the engaging hole 121 of the moving side rail substrate 12, and the flat surface portion of the connecting portion 501 is inserted. The outer peripheral convex surface of the rotary roller 561 is brought into close contact with the moving side rail substrate 12, along the lead-in guide path 7 provided on the fixed side rail 2, and using the fixing hole 501b and the screw hole 122, into a screw. The pull-in member 5 is attached to the slide rail 100 by fixing the member 5.

本発明は上記のように構成され、スライドレール１００の最短収縮状態（図１、図７に示す状態）では、軸部突出部５１（主、主回転軸５２）は、スライドレール１００の最収縮状態で引き込み案内路が変形する方向と対向側方向に突出している。そして、圧接子５６は、コイルバネ５４によって引き込み案内路７の下端部に弾性的に圧接し、常に移動側レール１を収納側方向に移動するよう付勢しているので、移動側レール１は不用意に引き出し側に引き出されることがなく、スライドレール１００の最短収縮状態を確実に維持することが出来る。 The present invention is configured as described above, and in the shortest contraction state of the slide rail 100 (states shown in FIGS. 1 and 7), the shaft portion protruding portion 51 (main, main rotating shaft 52) is the maximum contraction of the slide rail 100. In the state, the pull-in guide path protrudes in the direction opposite to the direction in which the guide path is deformed. The pressure welder 56 is elastically pressed against the lower end of the lead-in guide path 7 by the coil spring 54 to urge the moving side rail 1 to always move toward the storage side, so that the moving side rail 1 is not present. The slide rail 100 can be reliably maintained in the shortest contracted state without being easily pulled out to the drawer side.

そして、この状態から、移動側レール１が引き出されると、コイルバネ５４の付勢力に抗して回転腕５３は、図７で時計廻りに回動しながら、移動側レール１と共に前方に移動し、圧接子５６は引き込み案内路７から固定側レール２の上折曲縁２１の外面後端部に位置する。この時、圧接子５６の圧接方向が引き込み案内路７の形状変化によって、初期抵抗よりは小さな抵抗で移動側レール１は前方に移動し、次に、圧接子５６は固定側レール２の上折曲縁２１に位置し、コイルバネ５４の付勢力による抵抗はほとんどなくなった状態で移動側レール１は最大伸長状態まで引き出される。 Then, when the moving side rail 1 is pulled out from this state, the rotating arm 53 moves forward together with the moving side rail 1 while rotating clockwise in FIG. 7 against the urging force of the coil spring 54. The pressure welder 56 is located at the rear end of the outer surface of the upper bent edge 21 of the fixed side rail 2 from the lead-in guide path 7. At this time, the pressure contact direction of the pressure welder 56 is retracted, and the moving side rail 1 moves forward with a resistance smaller than the initial resistance due to the shape change of the guide path 7, and then the pressure welder 56 is folded upward on the fixed side rail 2. The moving side rail 1 is pulled out to the maximum extended state in a state where the resistance due to the urging force of the coil spring 54 is almost eliminated at the curved edge 21.

すなわち、移動側部材の引き出し始めは、使用者が強めの感覚で引き出す傾向があるのを利用し、引き込み案内路７を円弧状とすることで、円滑な摺動感覚を得ることが出来るだけでなく、引き込み案内路７、固定側レール２の上折曲縁２１が同形で連続して一体に形成されているので、微妙な段差もなく、圧接子５６が、引き込み案内路７から上折曲縁２１にそれぞれ移動する段階（逆の段階でも同じ。）においても何ら違和感を生じることがない。
又、スライドレール１００の最短収縮状態で、圧接子５６は円弧状の下向き方向の端部に圧接しているので、スライドレール１００の最短収縮状態を確実に維持する事が出来る。 That is, at the beginning of pulling out the moving side member, the user tends to pull out with a strong feeling, and by making the pull-in guide path 7 into an arc shape, it is only possible to obtain a smooth sliding feeling. Since the lead-in guideway 7 and the upper bend edge 21 of the fixed side rail 2 have the same shape and are continuously and integrally formed, the pressure welder 56 bends upward from the pull-in guideway 7 without a slight step. There is no sense of discomfort even at the stage of moving to the edges 21 (the same applies to the reverse stage).
Further, since the pressure welder 56 is in pressure contact with the arcuate downward end portion in the shortest contracted state of the slide rail 100, the shortest contracted state of the slide rail 100 can be reliably maintained.

そして、スライドレール１００の最大伸長状態から、移動側レール１を押し込んでいくと（移動側レール１と連結された移動側部材を収納していくと）、圧接子５６は、固定側レール２の上折曲縁２１の後端から引き込み案内路７に位置し、コイルバネ５４の付勢力によって、移動側レール１は自動的に引き込まれていく。
そして、コイルバネ５４の第１係止部５４２、第２係止部５４３の両端部が順次接近することでコイルバネ５４の付勢力が弱まるが、引き込み案内路７の収納側端部は下向きに突出する形状となっているので、圧接子５６の圧接方向がスライドレール１００の摺動方向となり、コイルバネ５４の付勢力の弱まりを補い、確実に最短縮小状態を維持する。 Then, when the moving side rail 1 is pushed in from the maximum extended state of the slide rail 100 (when the moving side member connected to the moving side rail 1 is stored), the pressure welder 56 becomes the fixed side rail 2. It is located in the pull-in guide path 7 from the rear end of the upper bending edge 21, and the moving side rail 1 is automatically pulled in by the urging force of the coil spring 54.
Then, both ends of the first locking portion 542 and the second locking portion 543 of the coil spring 54 approach each other in sequence, so that the urging force of the coil spring 54 weakens, but the storage side end of the lead-in guide path 7 projects downward. Since it has a shape, the pressure contact direction of the pressure welder 56 becomes the sliding direction of the slide rail 100, compensates for the weakening of the urging force of the coil spring 54, and reliably maintains the shortest reduced state.

さらに、回動腕５３を、ほぼ水平姿勢からほぼ垂直姿勢の範囲で回動可能に配設しているので、圧接子５６は、上下方向からスライド方向に順次移動できるから、引き込み案内路７がスライド方向に短くても、引き込みストロークを長く構成することができるので、スライドレール全体の長さを大きくしなくても、必要なスライドストロークを得ることができる。 Further, since the rotating arm 53 is rotatably arranged in a range from a substantially horizontal posture to a substantially vertical posture, the pressure welder 56 can be sequentially moved from the vertical direction to the sliding direction, so that the pull-in guide path 7 is provided. Since the pull-in stroke can be configured to be long even if it is short in the slide direction, the required slide stroke can be obtained without increasing the length of the entire slide rail.

そして、回転腕５３は、コイルバネ５４より移動側レール１側に配置され、固定腕５３のアーム部５３１より固定側レール２方向にコイルバネ５４が配置されるから、コイルバネ５４の巻き数設定が容易である。特に主回転軸５２の軸長を長くすることにより、コイルバネ５４の巻き数を増やすことも可能であり、その場合、回転腕５３は、移動側レール基板１２より外側（固定側レール２の対向側）に移動する。
スライドレール１００は、通常、固定側レール基板２２より外側（移動側レール１の対向側）への突出部が極力少ない方が使い勝手がよいことから、前記のように回転腕５３を、コイルバネ５４より移動側レール１側に配置させることにより、該固定側レール基板２２より外側への突出部を少なくした上で、コイルバネ５４の巻き数を増やすことが可能となる。
このように、回転腕５３をコイルバネ５４より移動側レール１側に配置し、かつ、回転腕５３を移動側レール基板１２より外側（固定側レール２の対向側）に配置できるように構成することにより、該固定側レール基板２２より外側への突出部をなくした上で、コイルバネ５４の巻き数を増やすことが可能となる。 Since the rotary arm 53 is arranged on the moving side rail 1 side from the coil spring 54 and the coil spring 54 is arranged in the fixed side rail 2 directions from the arm portion 531 of the fixed arm 53, it is easy to set the number of turns of the coil spring 54. be. In particular, it is possible to increase the number of turns of the coil spring 54 by lengthening the shaft length of the main rotating shaft 52, in which case the rotating arm 53 is outside the moving side rail substrate 12 (opposite side of the fixed side rail 2). ).
Since it is usually easier to use the slide rail 100 when the protrusion to the outside (opposite side of the moving side rail 1) from the fixed side rail substrate 22 is as small as possible, the rotating arm 53 is more convenient than the coil spring 54 as described above. By arranging it on the moving side rail 1 side, it is possible to increase the number of turns of the coil spring 54 while reducing the number of protrusions outward from the fixed side rail substrate 22.
In this way, the rotating arm 53 is arranged so as to be arranged on the moving side rail 1 side from the coil spring 54, and the rotating arm 53 can be arranged outside the moving side rail substrate 12 (on the opposite side of the fixed side rail 2). This makes it possible to increase the number of turns of the coil spring 54 while eliminating the protrusion to the outside from the fixed side rail substrate 22.

第２実施例、第３実施例は、第１実施例と回転腕５３やコイルバネ５４、引き込み案内路７、引き込み部材５の作用については同様であり、主に連結用支持部材５０の軸部突出部５１、主回転軸５２の構成が異なるものである。 The second embodiment and the third embodiment have the same operations as those of the first embodiment of the rotary arm 53, the coil spring 54, the pull-in guide path 7, and the pull-in member 5, and mainly the shaft portion of the connecting support member 50 protrudes. The configurations of the portion 51 and the main rotating shaft 52 are different.

そして、軸部突出部５１には、第１実施例と同様に主回転軸保持孔５１１が設けられている。 The second embodiment will be described.
In the second embodiment, as shown in FIG. 8, the concave groove 503 and the spring holding portion 504 of the connecting support member 50 are the same as those in the first embodiment, and the shaft portion protruding portion 51 is on the rear side of the connecting portion 501. The shaft portion protruding portion 51 is formed so as to project from the upper side toward the rear side, and the shaft portion protruding portion 51 is formed from the moving side rail board 12 so that the rotating arm 53 can be arranged outside the moving side rail board 12 (opposite side of the fixed side rail 2). It is formed so as to project outward (opposite side of the fixed side rail 2).
The shaft portion protruding portion 51 is provided with a main rotating shaft holding hole 511 as in the first embodiment.

主回転軸５２は、第１実施例と同様のものであるが、第１実施例と左右方向で逆向きに設置される。
そのため、コイルバネ５４を、コイル部５４１の第２係止部５４３側から、回転腕５３軸受部５３２に挿入し、第２係止部５４３を係止突片５３５の内側に係止させたあと、回転腕５３の貫通孔５３３に、軸受部５３２側から、主回転軸５２を固定軸部５２３側から挿入する。
挿入すると、貫通孔５３３の回転腕５３側から固定軸部５２３が飛び出した状態となり、該固定軸部５２３を、主回転軸保持孔５１１に固定側レール２側から挿入し、固定軸部５２３の先端をかしめると、主回転軸５２は回転腕５３を、主回転軸５２を軸として回転自在に保持しながら、軸部突出部５１に固定される。
この時、コイルバネ５４の第１係止部５４３を、連結用支持部材５０のバネ保持部５０４に係止させる。 The main rotation shaft 52 is the same as that of the first embodiment, but is installed in the opposite direction to the first embodiment in the left-right direction.
Therefore, the coil spring 54 is inserted into the rotary arm 53 bearing portion 532 from the second locking portion 543 side of the coil portion 541, and the second locking portion 543 is locked inside the locking projecting piece 535. The main rotating shaft 52 is inserted into the through hole 533 of the rotating arm 53 from the bearing portion 532 side and from the fixed shaft portion 523 side.
When inserted, the fixed shaft portion 523 protrudes from the rotating arm 53 side of the through hole 533, and the fixed shaft portion 523 is inserted into the main rotating shaft holding hole 511 from the fixed side rail 2 side, and the fixed shaft portion 523 is inserted. When the tip is crimped, the main rotating shaft 52 is fixed to the shaft portion protruding portion 51 while rotatably holding the rotating arm 53 around the main rotating shaft 52.
At this time, the first locking portion 543 of the coil spring 54 is locked to the spring holding portion 504 of the connecting support member 50.

このように、構成すると、回転腕５３をコイルバネ５４より移動側レール１側に配置し、かつ、回転腕５３を移動側レール基板１２より外側（固定側レール２の対向側）に配置できるように構成することが可能で、該固定側レール基板２２より外側への突出部をなくした上で、コイルバネ５４の巻き数を増やすことが可能となる。 With this configuration, the rotating arm 53 can be arranged on the moving side rail 1 side from the coil spring 54, and the rotating arm 53 can be arranged on the outside of the moving side rail substrate 12 (opposite side of the fixed side rail 2). It is possible to configure it, and it is possible to increase the number of turns of the coil spring 54 after eliminating the protrusion to the outside from the fixed side rail substrate 22.

次に、第３実施例について説明する。
第３実施例では、図９に示すように連結用支持部材５０の凹溝５０３、バネ保持部５０４は、軸部突出部５２、主回転軸保持孔５１１は、第１実施例と同様であって、第２軸部突出部５１ａが、第２実施例の軸部突出部５２と同様に、連結部５０１の後側上部から後側に向かって突出して形成され、第２軸部突出部５１ａは、回転腕５３を移動側レール基板１２より外側（固定側レール２の対向側）に配置できるように屈曲して形成されている。
そして、第２軸部突出部５１ａには、第２実施例と同様に第２主回転軸保持孔５１１ａが設けられている。 Next, the third embodiment will be described.
In the third embodiment, as shown in FIG. 9, the concave groove 503 of the connecting support member 50, the spring holding portion 504 has the shaft portion protruding portion 52, and the main rotating shaft holding hole 511 is the same as in the first embodiment. The second shaft portion protrusion 51a is formed so as to project from the rear upper portion of the connecting portion 501 toward the rear side, similarly to the shaft portion protrusion 52 of the second embodiment, and the second shaft portion protrusion 51a is formed.

主回転軸５２は、第１実施例と同様の形態ではあるが、主回転軸５２の軸長が第１実施例のものより長く設定されている。
そして、コイルバネ５４を、コイル部５４１の第２係止部５４３側から、回転腕５３軸受部５３２に挿入し、第２係止部５４３を係止突片５３５の内側に係止させたあと、軸部突出部５１と第２軸部突出部５１ａ間に、回転腕５３の軸受部５３２を配置し、回転腕５３の貫通孔５３３の中心線と、主回転軸保持孔５１１と第２主回転軸保持孔５１１ａを結ぶ中心線を一致させる。
次に、主回転軸５２を固定軸部５２３側から第２主回転軸保持孔５１１ａ側から挿入し、貫通孔５３３を貫通しながら、固定軸部５２３を主回転軸保持孔５１１から露呈させる。そして、固定軸部５２３の先端をかしめると、主回転軸５２は回転腕５３を、主回転軸５２を軸として回転自在に保持しながら、軸部突出部５１、第２軸部突出部５１ａ間に固定される。
この時、コイルバネ５４の第１係止部５４３を、連結用支持部材５０のバネ保持部５０４に係止させる。
このように、構成すると、主回転軸５２を両端で支えることが可能であるので、主回転軸５２が安定して設置可能となるので、回転腕５３の回動も安定して行うことが可能となる。 The main rotating shaft 52 has the same embodiment as that of the first embodiment, but the shaft length of the main rotating shaft 52 is set longer than that of the first embodiment.
Then, the coil spring 54 is inserted into the rotary arm 53 bearing portion 532 from the second locking portion 543 side of the coil portion 541, and the second locking portion 543 is locked inside the locking projecting piece 535.
