Description

【０００１】
【発明の属する技術分野】
本発明は自動車のドアなどボデーの凹みを内側から押し出して補修する際に用いる自動車ボデーの補修工具に関する。
【０００２】
【従来の技術】
自動車で走行中あるいは駐車中にボデーに何かが接触し、ボデーを凹ますことがある。凹みを補修する場合、修理工場やサービスセンターでは、一般的に専用の治具を使用する。補修に用いる治具として、例えば、特開平６−３２０４４２号公報「車体の補修方法及びその治具」に示されたものがある。この車体の補修治具１（符号は公報記載のものを流用した。以下同様。）は、同公報の図１によれば、断面円形状の金属製棒状体５の先端部に湾曲部６を介して先細りの頭部７ａを形成したもので、図７のように自動車のドアａの外板ｃと内板ｂとの間に補修治具１の頭部を挿入するとともに、頭部を凹み部ｅの裏面に当て、外側に押圧して凹み部ｅを同一面になるように補修することができるものである。
【０００３】
【発明が解決しようとする課題】
しかし、上記公報の車体の補修治具１をドアａの外板ｃと内板ｂとの間に挿入する場合に、例えば、外板ｃと内板ｂとの間に部材が設けられていると、部材に補修治具１の金属製棒状体５が干渉して凹み部ｅに頭部７ａを到達させることができないことがある。特に、最近は、衝突安全性能総合評価の評価点を向上させるために、ドア内に補強部材を配置するなどドア内の構造は複雑になりつつあり、内部材との干渉が起きやすい。
【０００４】
そこで、本発明の目的は、ボデーの内部材などの干渉物を避けてボデーの凹みを補修することができる自動車ボデーの補修工具を提供することにある。
【０００５】
【課題を解決するための手段】
上記目的を達成するために請求項１は、握り部から連続して延長部を設け、延長部の先端側に押圧部を形成した自動車ボデーの補修工具において、延長部を一方向の剛性に対して直交方向の剛性を大とし、一方向へは人手により折曲げ自在な長尺部材で構成したことを特徴とする。
【０００６】
延長部は、一方向の剛性に対して直交方向の剛性を大きく設定した。延長部を手で所望の形状に曲げることができるとともに、補修の際の力に対して曲げた状態を保持する強度を確保することができる。すなわち、延長部を曲げることで、ドア内に配設した補強部材との干渉を防止する。
【０００７】
請求項２は、延長部の断面を偏平に軟鉄にて形成し、断面の長辺方向に屈曲させて屈曲延長部を形成するとともに、屈曲延長部の先端に押圧部を形成したことを特徴とする。
【０００８】
軟鉄は、軟鋼と比較して、強度が小さく軟らかい。このような軟鉄で延長部を構成することで、延長部を手で曲げることができる。
また、延長部を偏平に軟鉄で構成したので、延長部を所望のねじれ角だけねじることができると同時に、所望の形状に曲げることができ、例えば、ボデー内に配設した補強部材との干渉を避けることができる。
【０００９】
請求項３は、延長部先端の押圧部を、握り部からのねじり力により回動する回転半径方向に突出する凸部としたことを特徴とする。
回転半径方向に突出する凸部としたことにより、回転力を凸部で補修箇所に集中的に付与でき、補修の精度が向上する。
【００１０】
請求項４では、握り部は、延長部に連続するＴ字形の水平バー部を備え、この水平バー部を握ってねじり力を延長部に付与自在としたことを特徴とする。
握り部をＴ字形としたので、作業者のねじり力を伝え易く、作業性が向上する。
【００１１】
【発明の実施の形態】
本発明の実施の形態を添付図に基づいて以下に説明する。なお、図面は符号の向きに見るものとする。
図１は本発明に係る自動車ボデーの補修工具の正面図であり、自動車ボデーの補修工具１０は、人Ｍの手で握る握り部１１から連続して延長部１２を設け、延長部１２の先端側を屈曲角度θだけ曲げるとともに、延長部１２の先端側に押圧部１３を形成したものである。
屈曲角度θは、１５°〜３０°に設定するのが好ましい。
押圧部１３は、握り部１１からのねじり力Ｆｃにより回動（矢印Ｆｃ′の方向）する回転半径方向（矢印ａ方向）に突出する凸部１３ａ，１３ａとした。
【００１２】
図２は本発明に係る自動車ボデーの補修工具の図１の斜視図であり、握り部１１と、延長部１２を示す。
握り部１１は、手で把持する水平バー部としてのグリップ１４と、グリップ１４の中央に取付けた延長部１２に連続する板材１５とからなり、板材１５とグリップ１４でＴ字形を形成したもので、作業者の指の間に板材１５を挟み且つ、Ｔ字形に形成したグリップ１４を手の平で握るこができるようにしたものである。
【００１３】
板材１５の材質は、例えば、軟鋼（ＪＩＳＳＳ４００）で、軟鋼は炭素含有量（Ｃ＝０．２５％以下）が少なく、引張り強さが４７Ｋｇｆ／ｍｍ²前後で、合金鋼に比較して軟らかい。
【００１４】
延長部１２は、直線部２１と、直線部２１から連続するとともに直線部２１に対して屈曲角度θだけ傾けて形成した傾倒部２２とからなり、断面を偏平断面の長方形に設定したものである。ｔは厚さ、Ｗは幅、１２ａは長辺、１２ｂは短辺を示す。偏平断面としては長方形などの四角形以外に、多角形を偏平にしたもの、管（角管も含む）や丸棒など円を偏平にしたものも含む。
【００１５】
また、延長部１２は、握り部１１の板材１５の先端１５ａに延長部１２の始端１２ｃを突合せ溶接にて接合し、握り部１１と一体化したものである。１２ｄは溶接後に凝固した溶接金属であるビードを示す。
【００１６】
延長部１２の材質は、軟鉄であるところの電磁軟鉄（ＪＩＳＳＵＹＰ）で、純鉄に近い材料である。
電磁軟鉄は、炭素含有量（Ｃ＝０．０１５％）が極めて少なく、引張り強さが３５ｋｇｆ／ｍｍ²前後で、軟鋼（ＪＩＳＳＳ４００）に比較してより軟らかいため、握り部１１の軟鋼より曲げ加工が容易であり、形状を含め人手により図３に示すように断面の厚さｔ方向（矢印▲２▼の方向）へ任意形状に屈曲形成できる程度の剛性とした。
【００１７】
以上に述べた自動車ボデーの補修工具の作用を次に説明する。
図３は本発明に係る自動車ボデーの補修工具の第１作用図である。
自動車ボデーの補修工具１０では、延長部１２を一方向（矢印▲２▼の方向）の剛性に対して直交方向（矢印▲１▼の方向）の剛性（断面係数）を大とし、一方向へは人手により折曲げ自在な長尺部材で構成したので、延長部１２を所望程度まで軟化させることができ、手で延長部１２を、例えば、それぞれ約４５°折曲げて第１曲げ部２３および第２曲げ部２４を形成することができる。
【００１８】
また、延長部１２を電磁軟鉄で構成したので、所望の強度を得ることができ、凹み補修の際に延長部１２のたわみを小さくすることができ、握り部１１から押圧部１３へ所望の力Ｆｘ，Ｆｙ，Ｆｚ，Ｆｃを伝えることができる。
【００１９】
さらに、延長部１２の厚さをｔ、幅をＷに設定して、断面を偏平な長方形としたので、図縦方向（矢印▲１▼の方向）の強度を大きく設定し、図縦方向（矢印▲１▼の方向）に交差する方向（矢印▲２▼の方向）の強度（断面係数）を小さく設定することができ、所望の形状に曲げることができる。
【００２０】
その上、延長部１２の厚さをｔ、幅をＷに設定して、断面を偏平な長方形としたので、図縦方向（矢印▲１▼の方向）の強度（断面係数）を大きく設定することができ、凹み補修の際に延長部１２のたわみをより小さくすることができる。従って、握り部１１から押圧部１３へ所望の力Ｆｘ，Ｆｙ，Ｆｚ，Ｆｃをより確実に伝えることができる。
【００２１】
図４は本発明に係る自動車ボデーの補修工具の第２作用図である。
自動車ボデーの補修工具１０で自動車のドア２５の凹み２６を補修する。具体的には、ドア２５は、アウタパネル３１と、インナパネル３２と、これらのアウタパネル３１とインナパネル３２の間に配設した補強部材３３と、開口部３４とを有するものである。このようなドア２５に凹み２６が発生した場合、まず、補修工具１０の延長部１２を、例えば、図４のように所望の形状に曲げ、続けて、開口部３４から補修工具１０を挿入し、凹み２６に補修工具１０の先端の押圧部１３を接近させる。その際、先端の押圧部１３がアウタパネル３１側に寄るように延長部１２を予め所定量だけ曲げて、補強部材３３との干渉を回避できるようにする。そして、補修工具１０の握り部１１を回してねじり力Ｆｃを発生させ、その時、延長部１２と補強部材３３とが干渉し、補強部材３３をテコの原理の支点の役目に利用し、作用点に相当する先端の押圧部１３で凹み２６を外側に矢印▲３▼の如く押し出す力を発生させ補修を行う。
【００２２】
このように、自動車ボデーの補修工具１０では、延長部１２の断面を偏平に軟鉄にて形成し、断面の長辺方向（図３の矢印▲２▼の方向）に屈曲させて屈曲延長部を形成するとともに、屈曲延長部の先端に押圧部１３を形成したので、ドア２５内に配設した補強部材３３を避けて、ドア２５の凹み２６に先端の押圧部１３を当てることができるとともに、凹み２６を外側に押し出して補修を行うことができる。
【００２３】
また、延長部１２の先端の押圧部１３を、握り部１１からのねじり力Ｆｃにより回動する回転半径方向に突出する凸部１３ａ，１３ａとしたので、回転力を補修箇所である凹み２６に矢印▲３▼の如く集中的に付与でき、補修の精度を向上させることができる。
【００２４】
握り部１１は、延長部１２に連続するＴ字形の水平バー部としてのグリップ１４を備え、このグリップ１４を握ってねじり力Ｆｃを延長部１２に付与自在としたので、作業者のねじり力Ｆｃを伝え易く、作業性が向上する。
【００２５】
図５（ａ），（ｂ）は本発明に係る自動車ボデーの補修工具の第３作用図である。
（ａ）において、自動車ボデー３５に凹み３６が発生した場合、補修工具１０の延長部１２をねじれ角β（（ｂ）参照）だけねじり、ねじり部３７を形成するとともに、所定形状に折曲げて曲げ部３８，３８を形成することで、補強部材４１やブラケット４２に干渉することなく、押圧部１３を凹み３６へ挿入することで補強部材４１やブラケット４２を回転時（矢印Ｆｃの方向）の支点として利用し、自動車ボデー３５の凹み３６を補修することができる。
【００２６】
（ｂ）は（ａ）のｂ−ｂ線断面図であり、延長部１２をねじれ角βだけねじった状態を示す。
このように、自動車ボデーの補修工具１０では、少なくとも延長部１２を軟鉄で構成したので、延長部１２を厚さｔ方向（矢印▲２▼の方向）に任意形状に曲げることができる。その結果、例えば、自動車ボデー３５内に配設した補強部材４１やブラケット４２を避けて、自動車ボデー３５の凹み３６に先端の押圧部１３を当てることができるとともに、幅方向（図３の矢印▲１▼の方向）の剛性により、押圧部１３への回転力伝達が行えることにより、凹み３６の押圧に必要な作用を発生し、補修を行うことができる。
【００２７】
尚、本発明の実施の形態に示した図１の補修工具１０では、延長部１２および押圧部１３を軟鉄で構成したが、押圧部１３を軟鉄以外で構成してもよい。
延長部１２とともに握り部１１の板材１５を軟鉄で構成してもよい。
また、補修工具１０を全て軟鉄で構成してもよい。
握り部１１の板材１５に軟鋼を採用したが、軟鋼以外に合金鋼を採用することも可能である。
【００２８】
【発明の効果】
本発明は上記構成により次の効果を発揮する。
請求項１では、握り部から連続して延長部を設け、延長部の先端側に押圧部を形成した自動車ボデーの補修工具において、延長部を一方向の剛性に対して直交方向の剛性を大とし、一方向へは人手により折曲げ自在な長尺部材で構成したので、延長部には、軟らかさとともに、所望の強度を与えることができる。その結果、延長部を所望の形状に曲げて、例えば、ドア内に配設した補強部材などの干渉物を避けて、ドアの凹みに先端の押圧部を当てることができるとともに、押し出し力を付与して凹みの補修を行うことができる。
【００２９】
請求項２では、延長部の断面を偏平に軟鉄にて形成し、断面の長辺方向に屈曲させて屈曲延長部を形成するとともに、屈曲延長部の先端に押圧部を形成したので、延長部には、軟らかさとともに、所望の強度を与えることができる。その結果、延長部を所望のねじれ角だけねじることができると同時に、所望の形状に曲げることができ、例えば、ボデー内に配設した補強部材などの干渉物を避けて、ボデーの凹みに先端の押圧部を当てることができるとともに、押し出し力を付与して凹みの補修を行うことができる。
【００３０】
請求項３では、延長部先端の押圧部を、握り部からのねじり力により回動する回転半径方向に突出する凸部としたので、回転力を凸部で補修箇所に集中的に付与でき、補修の精度を向上させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a repair tool for an automobile body that is used when an indentation of a body such as an automobile door is pushed out from the inside for repair.
[0002]
[Prior art]
Something may come in contact with the body while driving or parked, causing the body to dent. When repairing a dent, a repair shop or a service center generally uses a dedicated jig. As a jig used for repair, for example, there is one shown in Japanese Patent Application Laid-Open No. 6-320442 “Body repair method and jig”. According to FIG. 1 of the publication, the vehicle body repair jig 1 (the sign is the same as that described in the publication. The same applies hereinafter) has a curved portion 6 at the tip of a metal rod-like body 5 having a circular cross section. A tapered head 7a is formed, and the head of the repair jig 1 is inserted between the outer plate c and the inner plate b of the door a of the automobile as shown in FIG. It can be applied to the back surface of the part e and pressed outward to repair the recessed part e so as to be on the same surface.
[0003]
[Problems to be solved by the invention]
However, when the vehicle body repair jig 1 of the above publication is inserted between the outer plate c and the inner plate b of the door a, for example, a member is provided between the outer plate c and the inner plate b. In some cases, the metal bar 5 of the repair jig 1 interferes with the member, and the head 7a cannot reach the recess e. In particular, recently, in order to improve the evaluation point of the overall evaluation of collision safety performance, the structure in the door is becoming complicated, such as arranging a reinforcing member in the door, and interference with the inner member is likely to occur.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide an automobile body repair tool capable of repairing a body dent while avoiding interference such as an inner member of the body.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, claim 1 provides a repair tool for an automobile body in which an extension is provided continuously from a grip part, and a pressing part is formed on the distal end side of the extension. It is characterized by being made of a long member that has high rigidity in the orthogonal direction and can be bent manually in one direction.
[0006]
The extension portion has a greater rigidity in the orthogonal direction than the rigidity in one direction. The extension part can be bent into a desired shape by hand, and the strength for holding the bent state against the force at the time of repair can be ensured. That is, by bending the extension portion, interference with the reinforcing member disposed in the door is prevented.
[0007]
The second aspect of the present invention is characterized in that a cross section of the extension portion is formed flat with soft iron, bent in the long side direction of the cross section to form a bending extension portion, and a pressing portion is formed at the tip of the bending extension portion. To do.
[0008]
Mild iron has a lower strength and is softer than mild steel. By configuring the extension portion with such soft iron, the extension portion can be bent by hand.
In addition, since the extension portion is made of soft iron in a flat shape, the extension portion can be twisted by a desired twist angle, and at the same time, can be bent to a desired shape, for example, interference with a reinforcing member disposed in the body. Can be avoided.
[0009]
According to a third aspect of the present invention, the pressing portion at the distal end of the extension portion is a convex portion projecting in a rotational radius direction that is rotated by a torsional force from the grip portion.
By using the convex portion protruding in the rotational radius direction, the rotational force can be concentrated on the repaired portion by the convex portion, and the accuracy of repair is improved.
[0010]
According to a fourth aspect of the present invention, the grip portion includes a T-shaped horizontal bar portion continuous with the extension portion, and the torsional force can be freely applied to the extension portion by gripping the horizontal bar portion.
Since the grip portion is T-shaped, it is easy to transmit the torsional force of the operator, and the workability is improved.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings. The drawings are viewed in the direction of the reference numerals.
FIG. 1 is a front view of a repair tool for an automobile body according to the present invention. The repair tool 10 for an automobile body is provided with an extension portion 12 continuously from a grip portion 11 gripped by the hand of a person M, and the tip of the extension portion 12 is shown. The side is bent by a bending angle θ, and a pressing portion 13 is formed on the distal end side of the extension portion 12.
The bending angle θ is preferably set to 15 ° to 30 °.
The pressing portion 13 is convex portions 13a and 13a that protrude in the rotational radius direction (arrow a direction) that rotates (the direction of the arrow Fc ′) by the torsional force Fc from the grip portion 11.
[0012]
FIG. 2 is a perspective view of FIG. 1 of the repair tool for an automobile body according to the present invention, showing a grip 11 and an extension 12.
The grip portion 11 includes a grip 14 as a horizontal bar portion to be gripped by a hand, and a plate material 15 continuous to an extension portion 12 attached to the center of the grip 14, and the plate material 15 and the grip 14 form a T shape. The plate 15 is sandwiched between the fingers of the operator, and the grip 14 formed in a T shape can be gripped with the palm of the hand.
[0013]
The material of the plate 15 is, for example, mild steel (JIS SS400), which has a low carbon content (C = 0.25% or less) and a tensile strength of around 47 kgf / mm ² , which is softer than alloy steel. .
[0014]
The extension portion 12 includes a straight portion 21 and a tilted portion 22 that is continuous with the straight portion 21 and is inclined with respect to the straight portion 21 by a bending angle θ, and has a cross section set to a rectangular shape with a flat cross section. . t is the thickness, W is the width, 12a is the long side, and 12b is the short side. In addition to a quadrangle such as a rectangle, the flat cross section includes a flattened polygon, and a flattened circle such as a tube (including a square tube) or a round bar.
[0015]
The extension portion 12 is formed by joining the leading end 15 a of the plate member 15 of the grip portion 11 to the start end 12 c of the extension portion 12 by butt welding and integrating the grip portion 11. Reference numeral 12d denotes a bead which is a weld metal solidified after welding.
[0016]
The material of the extension portion 12 is electromagnetic soft iron (JIS SUYP), which is soft iron, and is a material close to pure iron.
Electromagnetic soft iron has a very low carbon content (C = 0.015%), a tensile strength of around 35 kgf / mm ² , and is softer than mild steel (JIS SS400). Processing was easy, and the rigidity was such that it could be bent into an arbitrary shape in the direction of the thickness t of the cross section (in the direction of arrow (2)) as shown in FIG.
[0017]
The operation of the vehicle body repair tool described above will now be described.
FIG. 3 is a first operation view of the repair tool for an automobile body according to the present invention.
In the repair tool 10 for an automobile body, the extension portion 12 is increased in rigidity (section modulus) in a direction orthogonal to the direction (in the direction of arrow (1)) with respect to the rigidity in one direction (in the direction of arrow (2)). Is formed of a long member that can be bent manually, so that the extension 12 can be softened to a desired degree. For example, the extension 12 can be bent by about 45 ° by hand, for example. The second bent portion 24 can be formed.
[0018]
Moreover, since the extension part 12 was comprised with electromagnetic soft iron, desired intensity | strength can be obtained, the bending of the extension part 12 can be made small in the case of dent repair, and desired force can be applied to the press part 13 from the grip part 11 Fx, Fy, Fz, Fc can be transmitted.
[0019]
Further, since the thickness of the extension portion 12 is set to t and the width is set to W, and the cross section is a flat rectangle, the strength in the vertical direction of the figure (the direction of arrow (1)) is set large, and the vertical direction of the figure ( The strength (section modulus) in the direction intersecting the direction of arrow (1) (direction of arrow (2)) can be set small, and can be bent into a desired shape.
[0020]
In addition, since the thickness of the extension portion 12 is set to t and the width is set to W, and the cross section is a flat rectangle, the strength (section modulus) in the vertical direction of the figure (in the direction of arrow (1)) is set large. The deflection of the extension portion 12 can be further reduced during the dent repair. Therefore, desired forces Fx, Fy, Fz, and Fc can be more reliably transmitted from the grip portion 11 to the pressing portion 13.
[0021]
FIG. 4 is a second action diagram of the automobile body repair tool according to the present invention.
The car body repair tool 10 repairs the dent 26 of the car door 25. Specifically, the door 25 includes an outer panel 31, an inner panel 32, a reinforcing member 33 disposed between the outer panel 31 and the inner panel 32, and an opening 34. When the dent 26 is generated in such a door 25, first, the extension portion 12 of the repair tool 10 is bent into a desired shape as shown in FIG. 4, for example, and then the repair tool 10 is inserted from the opening 34. The pressing portion 13 at the tip of the repair tool 10 is brought close to the recess 26. At that time, the extension portion 12 is bent in advance by a predetermined amount so that the pressing portion 13 at the tip approaches the outer panel 31 side, so that interference with the reinforcing member 33 can be avoided. Then, the grip portion 11 of the repair tool 10 is turned to generate a torsional force Fc. At that time, the extension portion 12 and the reinforcing member 33 interfere with each other, and the reinforcing member 33 is used as a fulcrum of the lever principle, Repair is performed by generating a force to push the dent 26 outward as indicated by the arrow (3) by the pressing portion 13 at the tip corresponding to.
[0022]
Thus, in the repair tool 10 for an automobile body, the cross section of the extension portion 12 is formed flat with soft iron and bent in the long side direction of the cross section (the direction of the arrow (2) in FIG. 3). Since the pressing portion 13 is formed at the tip of the bent extension portion, the pressing portion 13 at the tip can be applied to the recess 26 of the door 25 while avoiding the reinforcing member 33 disposed in the door 25, and Repair can be performed by pushing the recess 26 outward.
[0023]
Further, since the pressing portion 13 at the tip of the extension portion 12 is formed as the convex portions 13a and 13a protruding in the rotational radius direction rotated by the torsional force Fc from the grip portion 11, the rotational force is applied to the recess 26 which is a repair location. It can be applied intensively as indicated by arrow (3), and the accuracy of repair can be improved.
[0024]
The grip portion 11 includes a grip 14 as a T-shaped horizontal bar portion continuous with the extension portion 12, and the grip 14 is gripped so that a torsion force Fc can be freely applied to the extension portion 12. Is easy to convey and improves workability.
[0025]
FIGS. 5A and 5B are third operation views of the repair tool for the automobile body according to the present invention.
In (a), when a dent 36 is generated in the automobile body 35, the extension portion 12 of the repair tool 10 is twisted by a twist angle β (see (b)) to form a twist portion 37 and bent into a predetermined shape. By forming the bent portions 38, 38, the reinforcing member 41 and the bracket 42 are rotated (in the direction of the arrow Fc) by inserting the pressing portion 13 into the recess 36 without interfering with the reinforcing member 41 and the bracket 42. The dent 36 of the automobile body 35 can be repaired by using it as a fulcrum.
[0026]
(B) is a bb line sectional view of (a), and shows the state where extension part 12 was twisted only by twist angle β.
Thus, in the repair tool 10 for an automobile body, since at least the extension 12 is made of soft iron, the extension 12 can be bent into an arbitrary shape in the thickness t direction (the direction of arrow (2)). As a result, for example, the pressing member 13 at the tip can be applied to the recess 36 of the automobile body 35 while avoiding the reinforcing member 41 and the bracket 42 disposed in the automobile body 35, and in the width direction (arrow ▲ in FIG. 3). Since the rotational force can be transmitted to the pressing portion 13 by the rigidity in the direction of 1), an action necessary for pressing the recess 36 can be generated and repaired.
[0027]
In the repair tool 10 of FIG. 1 shown in the embodiment of the present invention, the extension portion 12 and the pressing portion 13 are made of soft iron, but the pressing portion 13 may be made of other than soft iron.
You may comprise the board | plate material 15 of the grip part 11 with the extension part 12 with a soft iron.
Moreover, you may comprise all the repair tools 10 with a soft iron.
Although mild steel is used for the plate 15 of the grip portion 11, alloy steel can also be used in addition to mild steel.
[0028]
【The invention's effect】
The present invention exhibits the following effects by the above configuration.
In claim 1, in the repair tool for an automobile body in which an extension is provided continuously from the grip part and a pressing part is formed on the distal end side of the extension, the extension has a rigidity in a direction orthogonal to the rigidity in one direction. And since it comprised with the elongate member which can be bent manually by one direction, a desired intensity | strength can be given to an extension part with softness | flexibility.
