Description

本発明は引戸装置において、建物壁の先端に取付ける方立枠との間に形成される隙間を防止する装置に関するものである。 The present invention relates to a sliding door device for preventing a gap formed between a standing frame attached to the end of a building wall.

図５は従来の一般的な引戸装置を示す概略図である。同図の（イ）は引戸、（ロ）は建物の壁、（ハ）は戸袋壁、（ニ）は引戸枠、（ホ）は方立枠をそれぞれ表している。同図に示している引戸（イ）は出入口（ヘ）を閉じているが、引戸（イ）が右側へスライドすれば、出入口（ヘ）は開口する。
ところで、同図のように引戸（イ）が閉じた場合、出入口（ヘ）は閉鎖されるが、方立枠（ホ）と引戸（イ）との間には隙間（ト）が介在し、この隙間（ト）を通じて室外から室内に光がもれたり、すきま風が吹き込んだりして室内にいる人々に不快感を与えるといった問題を有す。 FIG. 5 is a schematic view showing a conventional general sliding door device. In the figure, (a) represents a sliding door, (b) represents a building wall, (c) represents a door pocket wall, (d) represents a sliding door frame, and (e) represents a vertical frame. The sliding door (A) shown in the figure closes the entrance (f), but if the sliding door (A) slides to the right, the entrance (F) opens.
By the way, when the sliding door (I) is closed as shown in the figure, the doorway (F) is closed, but a gap (G) is interposed between the vertical frame (E) and the sliding door (I), There is a problem in that light leaks from the outside into the room through this gap (g), or a wind blows into the room, causing discomfort to people in the room.

図６は上記図５のＡ−Ａ断面拡大図を示しているが、両引戸枠（ニ），（ニ）の上端を上枠（チ）にて、下端を下枠（リ）にて連結した枠体が両壁（ロ）、（ロ）の間に形成した間口に嵌っている。引戸（イ）の上端は上枠（チ）のガイド溝（ヌ）に遊嵌し、引戸（イ）の下端は下枠（リ）に取付けたレール（ル）に載っている。そして、方立枠（ホ）と引戸（イ）の間には一定幅の隙間（ト）を有し、引戸（イ）は方立枠（ホ）に接することなく開閉することが出来る。 FIG. 6 shows an enlarged cross-sectional view taken along the line AA of FIG. 5 above. The fitted frame is fitted in the opening formed between both walls (b) and (b). The upper end of the sliding door (I) is loosely fitted in the guide groove (N) of the upper frame (H), and the lower end of the sliding door (I) is placed on the rail (L) attached to the lower frame (Li). A gap (g) having a certain width is provided between the vertical frame (e) and the sliding door (a), and the sliding door (a) can be opened and closed without contacting the vertical frame (e).

しかし、この隙間（ト）は、引戸（イ）を開閉操作するにあたって必要なクリアランスであり、この隙間（ト）が無いと引戸（イ）は方立枠（ホ）に接して開閉操作がし難くなり、しかも引戸表面にキズが付く。その為に、該隙間（ト）は引戸（イ）と方立枠（ホ）が接触しない必要最小限の大きさは必要となる。
その為、方立枠（ホ）の引戸側面に上記隙間（ト）の寸法と等しい長さのモヘアやパッキンなどの気密材（隙間防止材）を貼着し、該気密材を引戸側面に接触させることで隙間（ト）を塞いでいた。 However, this gap (g) is the clearance required to open and close the sliding door (a). Without this gap (g), the sliding door (a) contacts the vertical frame (e) and opens and closes. It becomes difficult and the surface of the sliding door is scratched. For this purpose, the gap (g) needs to have a minimum size so that the sliding door (b) and the vertical frame (e) do not contact each other.
Therefore, an airtight material (gap prevention material) such as mohair or packing with the same length as the gap (g) is attached to the side of the sliding door of the vertical frame (e), and the airtight material contacts the side of the sliding door. It was closing the gap (g) by doing.

このように方立枠（ホ）に気密材を取付けても、引戸（イ）に反りが発生した場合は該引戸（イ）と方立枠（ホ）間の隙間（ト）が拡大して該気密材にて隙間を閉ざすことが出来ない。また、方立枠（ホ）が反ることで引戸（イ）との間の隙間（ト）が拡大する場合もある。
一方、引戸（イ）を据え付けた後に、地震による建物自体の傾きによる躯体の変形、さらには施工ミスによる隙間（ト）の発生などにより気密材が該隙間（ト）を閉ざすことが出来ないことも多い。 In this way, even if the airtight material is attached to the vertical frame (e), if the sliding door (a) warps, the gap (g) between the sliding door (a) and the vertical frame (e) increases. The airtight material cannot close the gap. Moreover, the gap (g) between the sliding doors (a) may be expanded by warping the vertical frame (e).
On the other hand, after installing the sliding door (I), the airtight material cannot close the gap (g) due to deformation of the frame due to the inclination of the building itself due to the earthquake, or generation of gaps (g) due to construction mistakes, etc. There are also many.

そこで、従来では引戸（イ）と方立枠（ホ）との間に発生する隙間（ト）が変化した場合であっても対応できるようにした技術が開発されている。例えば、特開平１０−３３９０７７号に係る「引戸構造」は、方立ての引戸側側面に嵌入溝を設けるとともに、基材と、基材の表面に設けられる閉そく体からなり、引戸の側面と方立ての側面の間のクリアランスを閉そくする閉そく部材を、方立てに設けられる嵌入溝にその突出量を調整可能に嵌入している。
ところで、嵌入溝に嵌っている基材は閉そく材の表面から調整ビスを螺合して突出量を調整可能としている訳で、閉そく材の表面は引戸面と接していることから、調整は面倒である。すなわち、引戸を一旦取外して調整し、再度引戸を装着してクリアランスを見極めなくてはならない。 Therefore, conventionally, a technique has been developed that can cope with a case where the gap (g) generated between the sliding door (a) and the vertical frame (e) changes. For example, the “sliding door structure” according to Japanese Patent Application Laid-Open No. 10-339077 is provided with an insertion groove on the side surface of the sliding door and a base material and a closing body provided on the surface of the base material. A closing member that closes the clearance between the side surfaces of the uprights is inserted into an insertion groove provided in the upright so that the protruding amount can be adjusted.
By the way, the base material fitted in the insertion groove can be adjusted by screwing an adjusting screw from the surface of the closing material, so that the surface of the closing material is in contact with the sliding door surface. It is. That is, the sliding door must be removed and adjusted, and the sliding door must be mounted again to determine the clearance.

特開２００９−１２７３２１号に係る「引き戸の中方立構造」は、建物の壁などに設けられる引き戸枠の中方立構造において、加工が容易で、製造コストを低減することができるだけでなく、小さなトルクで広い範囲に隙間調整部材を動かすことができるコンパクトで取り扱いが容易な引き戸の中方立構造である。
そこで、隙間調整部材には、隙間調整部材の出没方向に沿ったラック部を有する長孔が形成されており、中方立部材には、長孔に対応した挿入孔が形成され、挿入孔には長孔に挿通されて長孔のラック部に噛合するピニオン部を有する回動調節部材を設けている。 The “neutral structure of sliding door” according to Japanese Patent Laid-Open No. 2009-127321 is a neutral structure of a sliding door frame provided on a wall of a building and the like, which is easy to process and can reduce the manufacturing cost, and also has a small torque. It is a neutral structure with a compact and easy to handle sliding door that can move the gap adjustment member over a wide range.
Therefore, the gap adjusting member is formed with a long hole having a rack portion along the protruding and retracting direction of the gap adjusting member, and the neutral member is formed with an insertion hole corresponding to the long hole. A rotation adjusting member having a pinion portion inserted through the long hole and meshing with the rack portion of the long hole is provided.

ところで、ピニオン部を有す回動調節部材は、隙間調節部材を調節した後に逆回転すると引戸との間に隙間が発生してしまう。すなわち、隙間調節部材は定位置に安定しない。
実用新案登録第３１８３８４０号に係る「引戸の隙間防止装置」は、出願人が以前に考案した技術であり、方立枠の引戸側面には凹溝を全長に亘って形成し、この凹溝には先端に引戸面に接するモヘアなどの隙間防止部材を取付けた遮蔽部材を嵌め、方立枠の出入口側面には調整部材を取着し、該調整部材は方立枠に設けた穴に回転しないように嵌った外輪と該外輪に嵌って回転する回転体から成り、回転体を回転することで連動機構を介して遮蔽部材が前進・後退移動するようにしている。 By the way, if the rotation adjusting member having the pinion part rotates reversely after adjusting the gap adjusting member, a gap is generated between the sliding adjusting member and the sliding door. That is, the gap adjusting member is not stable at a fixed position.
The “sliding door clearance prevention device” according to Utility Model Registration No. 3183840 is a technology previously devised by the applicant, and a concave groove is formed over the entire length of the sliding door side surface of the vertical frame. Fit a shielding member with a gap prevention member such as mohair that touches the sliding door surface at the tip, attach an adjustment member to the side of the entrance / exit of the vertical frame, and the adjustment member does not rotate into the hole provided in the vertical frame The outer ring fitted in this way and a rotating body that fits and rotates in the outer ring, and the shielding member moves forward and backward through the interlocking mechanism by rotating the rotating body.

このように、引戸と方立枠との間に生じる隙間を防止するための技術は色々存在している。しかし、何らかの原因（例えば、引戸の反り）で隙間が発生した場合には調整部材を操作することで隙間防止部材を移動する構造と成っているが、実際には隙間が生じてもそのまま放置している場合が殆どである。
特開平１０−３３９０７７号に係る「引戸構造」特開２００９−１２７３２１号に係る「引き戸の中方立構造」実用新案登録第３１８３８４０号に係る「引戸の隙間防止装置」 As described above, there are various techniques for preventing the gap generated between the sliding door and the vertical frame. However, when there is a gap due to some cause (for example, sliding door warpage), the gap prevention member is moved by operating the adjustment member. In most cases.
"Sliding door structure" according to Japanese Patent Laid-Open No. 10-339077 “Neutral structure of sliding door” according to Japanese Patent Application Laid-Open No. 2009-127321 "Gap prevention device for sliding doors" according to Utility Model Registration No. 3183840

このように、方立枠と引戸との間に隙間が生じないように調整する装置には上記のごとき問題がある。本発明が解決しようとする課題はこの問題点であり、方立枠と引戸との間に隙間が生じた際には、人が調整部材を操作することなく隙間防止部材を備えた遮蔽部材が自然に動いて隙間を塞ぐことが出来る隙間防止装置を提供する。 As described above, the apparatus for adjusting the gap so that no gap is generated between the vertical frame and the sliding door has the above-described problems. The problem to be solved by the present invention is this problem, and when a gap is generated between the vertical frame and the sliding door, the shielding member having the gap preventing member is not operated by a person without operating the adjustment member. Provided is a clearance prevention device that can move naturally and close the clearance.

本発明が対象とする引戸装置は、左右の壁面の間に形成された出入口を開閉する引戸を有し、この引戸が閉じた場合において該引戸の戸尻側面に近接する位置に方立枠を起立し、基本的な構造は従来の引戸装置と共通している。そして、方立枠の引戸側面には全長にわたって凹溝を形成し、該凹溝には遮蔽部材を嵌めて引戸面に向かって前進・後退移動を可能としている。該遮蔽部材は凹溝に嵌る基部と基部に沿って取付けたモヘアや柔らかい弾性片で構成した隙間防止部材を有している。 The sliding door device targeted by the present invention has a sliding door that opens and closes an entrance formed between the left and right wall surfaces, and when the sliding door is closed, a vertical frame is provided at a position close to the door bottom side of the sliding door. Standing up, the basic structure is common with the conventional sliding door device. A recessed groove is formed over the entire length of the sliding door side surface of the vertical frame, and a shielding member is fitted into the recessed groove so as to be able to move forward and backward toward the sliding door surface. The shielding member has a base portion that fits into the concave groove, and a gap prevention member that is formed of mohair attached along the base portion or a soft elastic piece.

上記凹溝に嵌る遮蔽部材には弾性力が付勢され、該遮蔽部材は弾性力によって凹溝から外へ突出するように動作する。従って、遮蔽部材に取付けられている隙間防止部材は常に前進し、引戸との間に隙間を生じることがないように機能することが出来る。
ここで、上記弾性力を付勢する弾性材の具体的な構造は限定しないが、板バネ、コイルバネ、又は樹脂製バネ等を使用することが出来る。 An elastic force is applied to the shielding member that fits into the groove, and the shielding member operates to protrude outward from the groove due to the elastic force. Therefore, the gap prevention member attached to the shielding member can always move forward and function so as not to cause a gap with the sliding door.
Here, the specific structure of the elastic member that urges the elastic force is not limited, but a plate spring, a coil spring, a resin spring, or the like can be used.

本発明に係る引戸の隙間防止装置は、方立枠に沿って設けた凹溝に隙間防止部材を取付けた遮蔽部材が嵌り、この遮蔽部材には弾性力が付勢されている。従って、遮蔽部材は弾性力の作用で凹溝から外へ突出するように作用し、その為に、隙間防止部材は引戸面に接し、隙間を生じることはない。
例えば、時の経過に伴って引戸が反り変形した場合、また方立枠が変形した場合であっても、遮蔽部材が突出することで隙間は生じない。すなわち、本発明では隙間が生じた場合に人が調整部材を操作して隙間防止部材を前進させる作業を必要とせず、弾性力の作用で遮蔽部材は自然に前進して隙間が塞がれる。 In the sliding door gap prevention device according to the present invention, a shielding member having a gap prevention member fitted in a recessed groove provided along the vertical frame is fitted, and an elastic force is urged on the shielding member. Therefore, the shielding member acts so as to protrude outward from the concave groove by the action of the elastic force. For this reason, the gap preventing member is in contact with the sliding door surface, and no gap is generated.
For example, even when the sliding door is warped and deformed with the passage of time or when the vertical frame is deformed, no gap is generated by the projection of the shielding member. That is, in the present invention, when a gap is generated, a person does not need to operate the adjustment member to advance the gap prevention member, and the shielding member naturally moves forward by the action of the elastic force to close the gap.

図１は引戸装置の出入口側を示す実施例で、同図の１は引戸、２は方立枠、３は上枠、４は下枠、５は隙間防止部材をそれぞれ表し、前記図６に相当する。従来の一般的な引戸装置では引戸１と方立枠２との間に隙間が介在しているが、本発明ではこの隙間を塞ぐために隙間防止部材５を取付けている。そこで、本発明が対象とする引戸装置としての形態は特に限定せず、片引き型式の引戸装置であっても、両引き型式の引戸装置であっても、また、上枠に取付けた上レールに引戸を吊設した型式の引戸装置であっても、下枠に敷設した下レールに引戸が載った型式の引戸装置であっても構わない。 FIG. 1 is an embodiment showing an entrance / exit side of a sliding door device. In FIG. 1, 1 is a sliding door, 2 is a vertical frame, 3 is an upper frame, 4 is a lower frame, and 5 is a gap prevention member. Equivalent to. In a conventional general sliding door device, a gap is interposed between the sliding door 1 and the vertical frame 2. In the present invention, a gap preventing member 5 is attached to close the gap. Therefore, the form of the sliding door device targeted by the present invention is not particularly limited, and it can be a single-drawing type sliding door device, a double-drawing type sliding door device, or an upper rail attached to the upper frame. Even if it is a type of sliding door device in which a sliding door is suspended, a sliding door device of a type in which a sliding door is placed on a lower rail laid on a lower frame may be used.

ところで、本発明に係る隙間防止装置は方立枠２に取着されて引戸１と方立枠２との間に発生する隙間を塞ぐことが出来る。
上記隙間防止部材５は立方枠２に固定された部材ではなく、引戸１が反り変形した場合、又は立方枠２が反り変形した場合に引戸面との間に隙間が発生しないように独りでに前進・後退をすることが出来るように構成している。すなわち、隙間が生じた際に、従来のような該隙間を塞ぐ為に隙間防止部材５を動かす調整部材を備えていない。 By the way, the gap preventing apparatus according to the present invention is attached to the vertical frame 2 and can close the gap generated between the sliding door 1 and the vertical frame 2.
The gap prevention member 5 is not a member fixed to the cubic frame 2, but when the sliding door 1 is warped and deformed, or when the cubic frame 2 is warped and deformed, the gap preventing member 5 is moved forward by itself so as not to generate a gap between the sliding door surface. It is configured to be able to retreat. That is, there is no adjustment member that moves the gap preventing member 5 to close the gap when a gap occurs.

図２は図１のＢ−Ｂ断面拡大図を示している。同図に示すように方立枠２の引戸側には凹溝６が長手方向に設けられ、この凹溝６には基部７と樹脂バネ８を有す遮蔽部材が嵌っている。そして、基部７には隙間防止部材５の１形態となるモヘア９が取付けられ、該モヘア９は引戸１にほぼ隙間なく接している。そして、上記遮蔽部材を構成する基部７には樹脂バネ８が一体成形され、樹脂バネ８の弾性力は基部７を外方向（引戸の方向）へ押出すように作用する。 FIG. 2 shows an enlarged cross-sectional view taken along the line BB of FIG. As shown in the figure, a recessed groove 6 is provided in the longitudinal direction on the sliding door side of the vertical frame 2, and a shielding member having a base 7 and a resin spring 8 is fitted in the recessed groove 6. And the mohair 9 used as one form of the clearance prevention member 5 is attached to the base 7, and the mohair 9 is in contact with the sliding door 1 with almost no gap. A resin spring 8 is integrally formed on the base 7 constituting the shielding member, and the elastic force of the resin spring 8 acts to push the base 7 outward (toward the sliding door).

したがって、モヘア９は引戸面に接することが出来、しかも柔らかいモヘア９が引戸面に接しても該引戸１の開閉操作に伴ってキズが付くことはない。勿論、本発明では上記モヘア９に限定することはなく、引戸面に接して滑ってもキズが付かない柔らかい材質から成る隙間防止部材５であれば構わない。 Therefore, the mohair 9 can be in contact with the sliding door surface, and even if the soft mohair 9 is in contact with the sliding door surface, the mohair 9 is not scratched with the opening / closing operation of the sliding door 1. Needless to say, the present invention is not limited to the mohair 9 as long as the gap preventing member 5 is made of a soft material that does not get scratched even if it slides in contact with the sliding door surface.

図３は遮蔽部材を示す具体例で、基部７と一体的に形成した樹脂バネ８を表す拡大図である。樹脂バネ８は概略楕円形断面の中空パイプ１０で構成され、この中空パイプ１０は繋ぎ１１ａを介して上記基部７と連結され、そして中空パイプ１０には繋ぎ１１ｂを介して羽根１２と連結し、さらに該羽根１２は繋ぎ１１ｃを介して羽根１３と連結している。上記各繋ぎ１１ａ，１１ｂ，１１ｃは基部７と中空パイプ１０、及び羽根１２，１３の中立部に設けられ、同図に示すように遮蔽部材は同一断面をした長尺材として構成している。 FIG. 3 is a specific example showing a shielding member, and is an enlarged view showing a resin spring 8 formed integrally with the base 7. The resin spring 8 is constituted by a hollow pipe 10 having a substantially elliptical cross section, and this hollow pipe 10 is connected to the base portion 7 through a connection 11a, and is connected to the blade 12 through the connection 11b. Further, the blade 12 is connected to the blade 13 through a joint 11c. The joints 11a, 11b, and 11c are provided at the neutral portion of the base 7, the hollow pipe 10, and the blades 12 and 13, and the shielding member is formed as a long material having the same cross section as shown in the figure.

上記基部７には開口１４が設けられ、この開口１４に隙間防止部材５であるモヘア９が嵌って取付けられる。ところで、基部７に上方から押圧力が作用するならば、該中空パイプ１０は圧縮変形して潰される。その為に、中空パイプ１０はその肉厚を薄くし、圧縮変形し易いように成っている。そして、両羽根１２，１３は方立枠２に設けた凹溝６に嵌合した際に、該凹溝６から外れないような幅寸法を有している。また、羽根１３の底には２個の凸片１５，１５を下方へ突出している。 An opening 14 is provided in the base 7, and a mohair 9 that is the gap preventing member 5 is fitted and attached to the opening 14. By the way, if a pressing force acts on the base portion 7 from above, the hollow pipe 10 is compressed and deformed and crushed. For this purpose, the hollow pipe 10 is made thin so that it can be easily compressed and deformed. Both the blades 12 and 13 have a width dimension so as not to be disengaged from the concave groove 6 when fitted into the concave groove 6 provided in the vertical frame 2. In addition, two convex pieces 15, 15 project downward from the bottom of the blade 13.

このように、上記樹脂バネ８を構成する中空パイプ１０は圧縮変形することが出来、その為に中空パイプ１０が圧縮された状態では元の形状（概略楕円形断面）に復元する為の弾性力が発生する。図３に示す樹脂バネ８は１本の中空パイプ１０を備えているが、２本の中空パイプ１０，１０を繋ぎを介して設けることも可能であり、そうすると圧縮変形量は２倍と成り、引戸１及び方立枠２のより大きな反り変形に追従することが出来る。 Thus, the hollow pipe 10 constituting the resin spring 8 can be compressed and deformed. Therefore, when the hollow pipe 10 is compressed, the elastic force for restoring the original shape (substantially elliptical cross section) is obtained. Will occur. The resin spring 8 shown in FIG. 3 includes a single hollow pipe 10, but it is also possible to provide two hollow pipes 10 and 10 via a connection, in which case the amount of compressive deformation is doubled, The larger warping deformation of the sliding door 1 and the vertical frame 2 can be followed.

図４は引戸１との間の隙間が変化した場合の樹脂バネ８の変化を表した具体例である。（ａ）は方立枠２と引戸１との間の隙間が小さい場合、（ｂ）は方立枠２と引戸１との間の隙間が拡大した場合を示している。
すなわち、初期セッティングの時には上記隙間が小さく、引戸１又は方立枠２が反り変形した場合に上記隙間がｈだけ拡大した場合であっても、上記樹脂バネ８の中空パイプ１０が変形することでモヘア９の先端は引戸面１６に常に接することが出来る。 FIG. 4 is a specific example showing the change of the resin spring 8 when the gap with the sliding door 1 changes. (A) shows the case where the gap between the vertical frame 2 and the sliding door 1 is small, and (b) shows the case where the gap between the vertical frame 2 and the sliding door 1 is enlarged.
That is, when the initial setting is performed, the gap is small, and even when the sliding door 1 or the vertical frame 2 is warped and deformed, the gap 10 is enlarged by h, so that the hollow pipe 10 of the resin spring 8 is deformed. The tip of the mohair 9 can always contact the sliding door surface 16.

上記のように中空パイプ１０の肉厚は薄く、その為に小さい押圧力によって圧縮変形することが出来、引戸面１６に柔らかいモヘア９が接した状態で引戸１をスライド開閉してもキズが付くことはない。
そして、基部７と中空パイプ１０、及び２枚の羽根１２，１３が各繋ぎ１１ａ，１１ｂ，１１ｃを介して連結した上記図３に示す長尺部材は一体成形されており、その為に製作コストは非常に安くなる。 As described above, the thickness of the hollow pipe 10 is thin, so that it can be compressed and deformed by a small pressing force, and even if the sliding door 1 is slid open and closed with the soft mohair 9 in contact with the sliding door surface 16, it is scratched. There is nothing.
The long member shown in FIG. 3 in which the base 7, the hollow pipe 10, and the two blades 12 and 13 are connected via the respective joints 11 a, 11 b, and 11 c is integrally formed, and thus the manufacturing cost is reduced. Will be very cheap.

ところで、基部７を外方向へ押出す為の弾性力は、上記実施例で説明した樹脂バネ８に限定するものではない。例えば、凹溝６にコイルバネ又は板バネを収容し、このバネの変形によって弾性力を基部７に付勢することも可能である。
一般に、引戸１を装着した場合に、方立枠２との間に隙間が生じないように隙間防止材５（例えば、モヘアなど）をセッティングするが、時の経過に伴って引戸１や方立枠２が反り変形することで隙間生じても、その都度、隙間防止材５を調整することはない。
しかし、本発明では、隙間の増減によって隙間防止材５の調整は不要と成り、樹脂バネ８の弾性力の作用で隙間防止材５は調整される。 By the way, the elastic force for extruding the base portion 7 in the outward direction is not limited to the resin spring 8 described in the above embodiment. For example, it is also possible to accommodate a coil spring or a leaf spring in the concave groove 6 and to bias the elastic force to the base portion 7 by deformation of this spring.
In general, when the sliding door 1 is mounted, a gap prevention material 5 (for example, mohair) is set so that no gap is generated between the sliding frame 1 and the sliding door 1 or the vertical wall as time passes. Even if a gap is generated by warping deformation of the frame 2, the gap prevention member 5 is not adjusted each time.
However, in the present invention, adjustment of the gap prevention member 5 becomes unnecessary due to increase / decrease of the gap, and the gap prevention member 5 is adjusted by the action of the elastic force of the resin spring 8.
