Description

本発明は、定着具及び定着具の製造方法に関する。 The present invention relates to a fixing tool and a method for manufacturing the fixing tool.

ロッドを対象物に定着させるための定着具が開発されている。特許文献１には、定着具の一例について記載されている。定着具は、ソケット及びウェッジを有している。ソケットは、内壁面を有している。ロッドは、ソケットの内壁面によって囲まれた領域を通過している。ソケットの内壁面は、ソケットの前方に行くほど直径が小さくなるように形成された円錐面をなしている。ウェッジは、ロッドの外周面とソケットの内壁面の間に位置している。ウェッジがソケットの前方に向けて移動することで、ウェッジがロッドの外周面とソケットの内壁面の間に強固に食い込む。これらの作用でロッドへの強い引張力に対し、耐えることが出来る。 Fixing tools for fixing the rod to the object have been developed. Patent Document 1 describes an example of a fixing tool. The fixing tool has a socket and a wedge. The socket has an inner wall surface. The rod passes through an area surrounded by the inner wall of the socket. The inner wall surface of the socket has a conical surface formed so that the diameter becomes smaller toward the front of the socket. The wedge is located between the outer peripheral surface of the rod and the inner wall surface of the socket. As the wedge moves toward the front of the socket, the wedge firmly bites between the outer peripheral surface of the rod and the inner wall surface of the socket. With these actions, it can withstand a strong tensile force on the rod.

以下、本発明の実施の形態について、図面を用いて説明する。尚、すべての図面において、同様な構成要素には同様の符号を付し、適宜説明を省略する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all drawings, similar components are designated by the same reference numerals, and description thereof will be omitted as appropriate.

図１は、実施形態に係る定着具１０を示す断面図である。図２は、図１のＡ−Ａ´断面図である。図２は、図１に示したＺ方向に垂直な断面を示している。説明のため、図２では、固定部材４００（図１）を示していない。 FIG. 1 is a cross-sectional view showing a fixing tool 10 according to an embodiment. FIG. 2 is a cross-sectional view taken along the line AA'of FIG. FIG. 2 shows a cross section perpendicular to the Z direction shown in FIG. For the sake of explanation, FIG. 2 does not show the fixing member 400 (FIG. 1).

図２を用いて、定着具１０の概要を説明する。定着具１０は、筒状部材１００、ロッド２００及び部材３００を備えている。筒状部材１００は、内側面１１２を有している。内側面１１２は、内部空間１１０を画定している。ロッド２００は、筒状部材１００の一断面（図２に示す断面）において筒状部材１００の内部空間１１０内に外側面２１２を有している。部材３００は、第１面３１２及び第２面３１４を有している。当該一断面（図２に示す断面）において、第１面３１２は、筒状部材１００の内側面１１２に対向しており、第２面３１４は、ロッド２００の外側面２１２に対向している。部材３００は、樹脂からなっている。 The outline of the fixing tool 10 will be described with reference to FIG. The fixing tool 10 includes a tubular member 100, a rod 200, and a member 300. The tubular member 100 has an inner side surface 112. The inner side surface 112 defines the internal space 110. The rod 200 has an outer surface 212 in the internal space 110 of the tubular member 100 in one cross section (cross section shown in FIG. 2) of the tubular member 100. The member 300 has a first surface 312 and a second surface 314. In the one cross section (cross section shown in FIG. 2), the first surface 312 faces the inner side surface 112 of the tubular member 100, and the second surface 314 faces the outer surface 212 of the rod 200. The member 300 is made of resin.

上述した構成によれば、ロッド２００を強固に固定することが可能になる。具体的には、部材３００は、樹脂からなっている。したがって、部材３００は、弾性的に変形することが可能になっている。したがって、部材３００とロッド２００の間では、部材３００の弾性変形によって部材３００からロッド２００に向かう方向に力が加わり、部材３００と筒状部材１００の間では、部材３００から筒状部材１００に向かう方向に力が加わる。このようにして、ロッド２００を強固に固定することが可能になる。 According to the above-described configuration, the rod 200 can be firmly fixed. Specifically, the member 300 is made of resin. Therefore, the member 300 can be elastically deformed. Therefore, between the member 300 and the rod 200, a force is applied in the direction from the member 300 to the rod 200 due to the elastic deformation of the member 300, and between the member 300 and the tubular member 100, the force is directed from the member 300 toward the tubular member 100. Force is applied in the direction. In this way, the rod 200 can be firmly fixed.

図１を用いて、定着具１０の詳細を説明する。 The details of the fixing tool 10 will be described with reference to FIG.

図１に示す例では、対象物Ｏにロッド２００が定着されている。対象物Ｏは、面Ｓを有している。定着具１０は、対象物Ｏの面Ｓ上に位置している。 In the example shown in FIG. 1, the rod 200 is fixed to the object O. The object O has a surface S. The fixing tool 10 is located on the surface S of the object O.

筒状部材１００は、第１端１０２及び第２端１０４を有している。ロッド２００の軸方向（図１内のＺ方向）において、第１端１０２は、筒状部材１００の一端であり、第２端１０４は、第１端１０２の反対側の一端である。筒状部材１００の内側面１１２は、第１端１０２から第２端１０４に向けてテーパ形状を有している。具体的には、ロッド２００の軸方向（図１内のＺ方向）に垂直な断面（例えば、図２に示す断面）において筒状部材１００の内側面１１２によって囲まれた領域の面積（図２の内部空間１１０の断面積）は、筒状部材１００の第１端１０２から第２端１０４に向かうにつれて小さくなっている。 The tubular member 100 has a first end 102 and a second end 104. In the axial direction of the rod 200 (Z direction in FIG. 1), the first end 102 is one end of the tubular member 100, and the second end 104 is the opposite end of the first end 102. The inner side surface 112 of the tubular member 100 has a tapered shape from the first end 102 to the second end 104. Specifically, the area of the region surrounded by the inner side surface 112 of the tubular member 100 in the cross section (for example, the cross section shown in FIG. 2) perpendicular to the axial direction of the rod 200 (Z direction in FIG. 1) (FIG. 2). The cross-sectional area of the internal space 110) becomes smaller from the first end 102 to the second end 104 of the tubular member 100.

部材３００は、第１端３０２及び第２端３０４を有している。ロッド２００の軸方向（図１内のＺ方向）において、第１端３０２は、部材３００の一端であり、筒状部材１００の第１端１０２と同じ側に位置しており、第２端３０４は、第１端３０２の反対側の一端であり、筒状部材１００の第２端１０４と同じ側に位置している。部材３００は、第１端３０２から第２端３０４に向けてテーパ形状を有している。具体的には、ロッド２００の軸方向（図１内のＺ方向）に垂直な断面（例えば、図２に示す断面）における部材３００の断面積は、部材３００の第１端３０２から第２端３０４に向かうにつれて小さくなっている。 The member 300 has a first end 302 and a second end 304. In the axial direction of the rod 200 (Z direction in FIG. 1), the first end 302 is one end of the member 300, is located on the same side as the first end 102 of the tubular member 100, and is located at the second end 304. Is one end on the opposite side of the first end 302, and is located on the same side as the second end 104 of the tubular member 100. The member 300 has a tapered shape from the first end 302 to the second end 304. Specifically, the cross-sectional area of the member 300 in the cross section (for example, the cross section shown in FIG. 2) perpendicular to the axial direction of the rod 200 (Z direction in FIG. 1) is the first end 302 to the second end of the member 300. It becomes smaller toward 304.

一例において、筒状部材１００は、部材３００に対して、部材３００の第２端３０４から第１端３０２に向かう方向に移動可能にすることができる。この例においては、部材３００をロッド２００と筒状部材１００によって強固に締め付けることができる。 In one example, the tubular member 100 can be made movable with respect to the member 300 in the direction from the second end 304 to the first end 302 of the member 300. In this example, the member 300 can be firmly tightened by the rod 200 and the tubular member 100.

他の例において、部材３００は、筒状部材１００に対して、筒状部材１００の第１端１０２から第２端１０４に向かう方向に移動可能にすることができる。この例においても、部材３００をロッド２００と筒状部材１００によって強固に締め付けることができる。 In another example, the member 300 can be made movable with respect to the tubular member 100 in the direction from the first end 102 to the second end 104 of the tubular member 100. Also in this example, the member 300 can be firmly tightened by the rod 200 and the tubular member 100.

図１に示す例では、筒状部材１００は、固定部材４００によって対象物Ｏの面Ｓに固定されている。本実施形態の説明から明らかなように、筒状部材１００を対象物Ｏの面Ｓに固定する方法は、図１に示す例（固定部材４００）に限定されるものではない。 In the example shown in FIG. 1, the tubular member 100 is fixed to the surface S of the object O by the fixing member 400. As is clear from the description of the present embodiment, the method of fixing the tubular member 100 to the surface S of the object O is not limited to the example (fixing member 400) shown in FIG.

図１に示す例では、筒状部材１００は、保持部材５００によって、部材３００に対して、部材３００の第２端３０４から第１端３０２に向かう方向に移動可能になっている。つまり、保持部材５００は、部材３００の第２端３０４から第１端３０２に向かう方向に筒状部材１００を引っ張り可能になっている。したがって、上述したように、部材３００をロッド２００と筒状部材１００によって強固に締め付けることができる。本実施形態の説明から明らかなように、部材３００をロッド２００と筒状部材１００によって締め付ける方法は、図１に示す例に限定されるものではない。上述したように、部材３００が筒状部材１００に対して筒状部材１００の第１端１０２から第２端１０４に向かう方向に移動可能になっていてもよい。つまり、筒状部材１００の第１端１０２から第２端１０４に向かう方向に部材３００を押し込むことが可能になっていてもよい。 In the example shown in FIG. 1, the tubular member 100 is movable with respect to the member 300 in the direction from the second end 304 to the first end 302 of the member 300 by the holding member 500. That is, the holding member 500 can pull the tubular member 100 in the direction from the second end 304 to the first end 302 of the member 300. Therefore, as described above, the member 300 can be firmly tightened by the rod 200 and the tubular member 100. As is clear from the description of the present embodiment, the method of tightening the member 300 by the rod 200 and the tubular member 100 is not limited to the example shown in FIG. As described above, the member 300 may be movable with respect to the tubular member 100 in the direction from the first end 102 to the second end 104 of the tubular member 100. That is, it may be possible to push the member 300 in the direction from the first end 102 to the second end 104 of the tubular member 100.

図２を用いて、定着具１０の詳細をさらに説明する。図２は、ロッド２００の軸方向（図１内のＺ方向）に垂直な断面を示している。 The details of the fixing tool 10 will be further described with reference to FIG. FIG. 2 shows a cross section perpendicular to the axial direction of the rod 200 (Z direction in FIG. 1).

図２に示す例では、複数の部材３００（具体的には、３つの部材３００）がロッド２００の外側面２１２に沿って並んでいる。本実施形態の説明から明らかなように、ロッド２００の外側面２１２に沿って並ぶ部材３００の数は、図２に示す例（３つ）に限定されるものではない。 In the example shown in FIG. 2, a plurality of members 300 (specifically, three members 300) are arranged along the outer surface 212 of the rod 200. As is clear from the description of the present embodiment, the number of members 300 arranged along the outer surface 212 of the rod 200 is not limited to the example (three) shown in FIG.

筒状部材１００の内部空間１１０の形状は、実質的に円となっている。筒状部材１００の内側面１１２は、部材３００の第１面３１２に対向する領域において第１曲率（１／Ｒ１）（Ｒ１は、内側面１１２に沿った円周の半径を示す。）で湾曲している。 The shape of the internal space 110 of the tubular member 100 is substantially circular. The inner surface 112 of the tubular member 100 is curved with a first curvature (1 / R1) (R1 indicates the radius of the circumference along the inner surface 112) in the region of the member 300 facing the first surface 312. doing.

部材３００の第１面３１２は、第２曲率（１／Ｒ２）（Ｒ２は、第１面３１２に沿った円周の半径を示す。）で湾曲している。第２曲率は、第１曲率より大きい（つまり、Ｒ２＜Ｒ１）。 The first surface 312 of the member 300 is curved with a second curvature (1 / R2) (R2 indicates the radius of the circumference along the first surface 312). The second curvature is greater than the first curvature (ie, R2 <R1).

部材３００の第１面３１２は、第１領域３１２ａ、第２領域３１２ｂ及び第３領域３１２ｃを有している。第１領域３１２ａ及び第２領域３１２ｂは、筒状部材１００の内側面１１２から離間している。第３領域３１２ｃは、第１領域３１２ａと第２領域３１２ｂの間にあって、第１領域３１２ａ及び第２領域３１２ｂよりも筒状部材１００の内側面１１２に近接している。 The first surface 312 of the member 300 has a first region 312a, a second region 312b, and a third region 312c. The first region 312a and the second region 312b are separated from the inner side surface 112 of the tubular member 100. The third region 312c is located between the first region 312a and the second region 312b and is closer to the inner surface 112 of the tubular member 100 than the first region 312a and the second region 312b.

上述した構成によれば、図４及び図５を用いて後述するように、部材３００を筒状部材１００とロッド２００によって強固に締め付けることができ、かつ、筒状部材１００とロッド２００による締め付けによる部材３００の破損を抑えることができる。 According to the above-described configuration, as will be described later with reference to FIGS. 4 and 5, the member 300 can be firmly tightened by the tubular member 100 and the rod 200, and by tightening by the tubular member 100 and the rod 200. Damage to the member 300 can be suppressed.

ロッド２００の形状は、実質的に円となっている。ロッド２００の外側面２１２は、部材３００の第２面３１４に対向する領域において第３曲率（１／Ｒ３）（Ｒ３は、外側面２１２に沿った円周の半径を示す。）で湾曲している。 The shape of the rod 200 is substantially circular. The outer surface 212 of the rod 200 is curved with a third curvature (1 / R3) (R3 indicates the radius of the circumference along the outer surface 212) in the region of the member 300 facing the second surface 314. There is.

部材３００の第２面３１４は、第４曲率（１／Ｒ４）（Ｒ４は、第２面３１４に沿った円周の半径を示す。）で湾曲している。第４曲率は、第３曲率と同じ又は第３曲率より小さい（つまり、Ｒ４≧Ｒ３）。 The second surface 314 of the member 300 is curved with a fourth curvature (1 / R4) (R4 indicates the radius of the circumference along the second surface 314). The fourth curvature is the same as or smaller than the third curvature (ie, R4 ≧ R3).

部材３００の第２面３１４は、第１領域３１４ａ、第２領域３１４ｂ及び第３領域３１４ｃを有している。第１領域３１４ａ及び第２領域３１４ｂは、ロッド２００の外側面２１２から離間している。第３領域３１４ｃは、第１領域３１４ａと第２領域３１４ｂの間にあって、第１領域３１４ａ及び第２領域３１４ｂよりもロッド２００の外側面２１２に近接している。 The second surface 314 of the member 300 has a first region 314a, a second region 314b, and a third region 314c. The first region 314a and the second region 314b are separated from the outer surface 212 of the rod 200. The third region 314c is located between the first region 314a and the second region 314b and is closer to the outer surface 212 of the rod 200 than the first region 314a and the second region 314b.

上述した構成によれば、図４及び図５を用いて後述するように、部材３００を筒状部材１００とロッド２００によって強固に締め付けることができ、かつ、筒状部材１００とロッド２００の締め付けによる部材３００の破損を抑えることができる。 According to the above-described configuration, as will be described later with reference to FIGS. 4 and 5, the member 300 can be firmly tightened by the tubular member 100 and the rod 200, and by tightening the tubular member 100 and the rod 200. Damage to the member 300 can be suppressed.

一例において、筒状部材１００は、樹脂又は金属からなっている。 In one example, the tubular member 100 is made of resin or metal.

一例において、ロッド２００は、樹脂、具体的には、例えば、ＦＲＰ（Ｆｉｂｅｒ−ＲｅｉｎｆｏｒｃｅｄＰｌａｓｔｉｃｓ）からなっている。 In one example, the rod 200 is made of a resin, specifically, for example, FRP (Fiber-Reinforced Plastics).

部材３００は、樹脂からなっている。したがって、部材３００は、弾性的に変形することが可能になっている。したがって、上述したように、ロッド２００を強固に固定することが可能になる。 The member 300 is made of resin. Therefore, the member 300 can be elastically deformed. Therefore, as described above, the rod 200 can be firmly fixed.

図３は、ロッド２００の外側面２１２と部材３００の第２面３１４の間の詳細の一例を説明するための図である。図３は、図１に示したＺ方向に沿った断面を示している。 FIG. 3 is a diagram for explaining a detailed example between the outer surface 212 of the rod 200 and the second surface 314 of the member 300. FIG. 3 shows a cross section along the Z direction shown in FIG.

ロッド２００の外側面２１２と部材３００の第２面３１４の間には、接着剤６００が位置している。したがって、接着剤６００によって、ロッド２００の外側面２１２と部材３００の第２面３１４を強固に接合させることができる。 The adhesive 600 is located between the outer surface 212 of the rod 200 and the second surface 314 of the member 300. Therefore, the adhesive 600 can firmly join the outer surface 212 of the rod 200 and the second surface 314 of the member 300.

部材３００の第２面３１４には、溝３１６が形成されている。接着剤６００の一部は、溝３１６に埋め込まれている。したがって、ロッド２００の外側面２１２に対する接着剤６００の接触面を大きくすることができる。したがって、接着剤６００は、ロッド２００の外側面２１２に強固に接着することができる。 A groove 316 is formed on the second surface 314 of the member 300. A part of the adhesive 600 is embedded in the groove 316. Therefore, the contact surface of the adhesive 600 with respect to the outer surface 212 of the rod 200 can be increased. Therefore, the adhesive 600 can be firmly adhered to the outer surface 212 of the rod 200.

図４及び図５は、部材３００を筒状部材１００とロッド２００によって締め付ける方法の一例を説明するための図である。 4 and 5 are views for explaining an example of a method of tightening the member 300 with the tubular member 100 and the rod 200.

上述したように、ロッド２００の軸方向（図１内のＺ方向）に沿って、筒状部材１００が部材３００に対して移動し、又は部材３００が筒状部材１００に対して移動することで、部材３００を筒状部材１００とロッド２００によって締め付けることができる。図４は、筒状部材１００又は部材３００が移動する前の状態を示しており、図５は、筒状部材１００又は部材３００が移動した後の状態を示している。 As described above, the tubular member 100 moves with respect to the member 300 or the member 300 moves with respect to the tubular member 100 along the axial direction of the rod 200 (Z direction in FIG. 1). , The member 300 can be tightened by the tubular member 100 and the rod 200. FIG. 4 shows a state before the tubular member 100 or the member 300 moves, and FIG. 5 shows a state after the tubular member 100 or the member 300 moves.

図４においては、部材３００の第１面３１２は、筒状部材１００の内側面１１２とほぼ一点のみで接触している。同様にして、部材３００の第２面３１４は、ロッド２００の外側面２１２とほぼ一点のみで接触している。なお、部材３００は、筒状部材１００及びロッド２００に直接接触していてもよいし、又は特定の材料（例えば、図３に示した接着剤６００）を介して筒状部材１００及びロッド２００に接触していてもよい。 In FIG. 4, the first surface 312 of the member 300 is in contact with the inner surface 112 of the tubular member 100 at substantially only one point. Similarly, the second surface 314 of the member 300 is in contact with the outer surface 212 of the rod 200 at substantially only one point. The member 300 may be in direct contact with the tubular member 100 and the rod 200, or may be attached to the tubular member 100 and the rod 200 via a specific material (for example, the adhesive 600 shown in FIG. 3). It may be in contact.

これに対して、図５においては、部材３００の第１面３１２と筒状部材１００の内側面１１２の接触領域が広がり、部材３００の第１面３１２のほぼ全面が筒状部材１００の内側面１１２に接触している。同様にして、部材３００の第２面３１４とロッド２００の外側面２１２の接触領域も広がり、部材３００の第２面３１４のほぼ全面がロッド２００の外側面２１２に接触している。 On the other hand, in FIG. 5, the contact area between the first surface 312 of the member 300 and the inner surface 112 of the tubular member 100 is widened, and almost the entire surface of the first surface 312 of the member 300 is the inner surface of the tubular member 100. It is in contact with 112. Similarly, the contact area between the second surface 314 of the member 300 and the outer surface 212 of the rod 200 is also widened, and almost the entire surface of the second surface 314 of the member 300 is in contact with the outer surface 212 of the rod 200.

図５に示す例によれば、筒状部材１００からの力を部材３００の第１面３１２のほぼ全面で受けることができ、ロッド２００からの力を部材３００の第２面３１４のほぼ全面で受けることができる。したがって、部材３００は、筒状部材１００から受ける抗力及びロッド２００から受ける抗力に耐えることができる。したがって、部材３００を筒状部材１００とロッド２００によって強固に締め付けることができる。 According to the example shown in FIG. 5, the force from the tubular member 100 can be received on almost the entire surface of the first surface 312 of the member 300, and the force from the rod 200 can be received on almost the entire surface of the second surface 314 of the member 300. Can receive. Therefore, the member 300 can withstand the drag force received from the tubular member 100 and the drag force received from the rod 200. Therefore, the member 300 can be firmly tightened by the tubular member 100 and the rod 200.

図４及び図５に示す例によれば、部材３００の第１面３１２と筒状部材１００の内側面１１２の接触領域は、第１面３１２のほぼ中央（第３領域３１２ｃ及びその周辺）（図４）からその周辺（第１領域３１２ａ及び第２領域３１２ｂ）（図５）に広がる。したがって、部材３００を筒状部材１００とロッド２００によって締め付けても、筒状部材１００の内側面１１２からの力が部材３００の第１面３１２の特定の一点のみに集中しないようにすることができる。したがって、筒状部材１００とロッド２００の締め付けによる部材３００の破損を抑えることができる。 According to the examples shown in FIGS. 4 and 5, the contact region between the first surface 312 of the member 300 and the inner surface 112 of the tubular member 100 is substantially in the center of the first surface 312 (third region 312c and its periphery) (3rd region 312c and its periphery). It extends from FIG. 4) to its surroundings (first region 312a and second region 312b) (FIG. 5). Therefore, even if the member 300 is tightened by the tubular member 100 and the rod 200, the force from the inner surface 112 of the tubular member 100 can be prevented from concentrating only on a specific point on the first surface 312 of the member 300. .. Therefore, damage to the member 300 due to tightening of the tubular member 100 and the rod 200 can be suppressed.

図４及び図５に示す例によれば、部材３００の第２面３１４とロッド２００の外側面２１２の接触領域は、第２面３１４のほぼ中央（第３領域３１４ｃ及びその周辺）（図４）からその周辺（第１領域３１４ａ及び第２領域３１４ｂ）（図５）に広がる。したがって、部材３００を筒状部材１００とロッド２００によって締め付けても、ロッド２００の外側面２１２からの力が部材３００の第２面３１４の特定の一点のみに集中しないようにすることができる。したがって、筒状部材１００とロッド２００の締め付けによる部材３００の破損を抑えることができる。 According to the examples shown in FIGS. 4 and 5, the contact region between the second surface 314 of the member 300 and the outer surface 212 of the rod 200 is substantially in the center of the second surface 314 (third region 314c and its periphery) (FIG. 4). ) To its surroundings (first region 314a and second region 314b) (FIG. 5). Therefore, even if the member 300 is tightened by the tubular member 100 and the rod 200, the force from the outer surface 212 of the rod 200 can be prevented from being concentrated on only one specific point on the second surface 314 of the member 300. Therefore, damage to the member 300 due to tightening of the tubular member 100 and the rod 200 can be suppressed.

図６は、部材３００の変形例を示す図である。 FIG. 6 is a diagram showing a modified example of the member 300.

部材３００の第１面３１２は、第１領域３１２ａ、第２領域３１２ｂ及び第３領域３１２ｃを有している。第３領域３１２ｃは、第１領域３１２ａと第２領域３１２ｂの間にあって、実質的に平坦になっている。第１領域３１２ａ及び第２領域３１２ｂは、湾曲している。 The first surface 312 of the member 300 has a first region 312a, a second region 312b, and a third region 312c. The third region 312c is between the first region 312a and the second region 312b and is substantially flat. The first region 312a and the second region 312b are curved.

上述した構成によれば、図４及び図５に示したように部材３００を筒状部材１００とロッド２００によって締め付けるとき、第１面３１２の第３領域３１２ｃが第１面３１２の第１領域３１２ａ及び第２領域３１２ｂよりも先に筒状部材１００の内側面１１２に接触する。第１面３１２の第３領域３１２ｃは平坦になっているため、筒状部材１００の内側面１１２から部材３００から受ける力を第３領域３１２ｃによってほぼ均一に分布させることができる。 According to the above configuration, when the member 300 is tightened by the tubular member 100 and the rod 200 as shown in FIGS. 4 and 5, the third region 312c of the first surface 312 becomes the first region 312a of the first surface 312. And the inner side surface 112 of the tubular member 100 is contacted before the second region 312b. Since the third region 312c of the first surface 312 is flat, the force received from the member 300 from the inner side surface 112 of the tubular member 100 can be distributed substantially uniformly by the third region 312c.

By cutting the initial member 300a, the initial member 300a is separated into a plurality of members 300. In the example shown in FIG. 8, the initial member 300a is cut so that the cut (broken line L) formed by cutting the initial member 300a passes through the hole 322. By forming the holes 322 in advance, it becomes easy to separate the initial member 300a into a plurality of members 300.

次いで、図１０に示すように、部材３００の第１面３１２の反対側に第２面３１４が形成されるように部材３００を加工する。図１０に示す工程において、部材３００の第２面３１４に、図３に示した溝３１６を形成してもよい。 Next, as shown in FIG. 10, the member 300 is processed so that the second surface 314 is formed on the opposite side of the first surface 312 of the member 300. In the step shown in FIG. 10, the groove 316 shown in FIG. 3 may be formed on the second surface 314 of the member 300.

次いで、図１１に示すように、ロッド２００の外側面２１２が部材３００の第２面３１４に対向するように、ロッド２００を一方向（図１１（ａ）内のＺ方向）に沿って筒状部材１００の内部空間１１０内に挿入する。図１１（ｂ）に示す断面においては、図２に示した断面と同様にして、ロッド２００の外側面２１２は、部材３００の第２面３１４に対向する領域において第３曲率（１／Ｒ３）で湾曲しており、部材３００の第２面３１４は、第４曲率（１／Ｒ４）で湾曲しており、第４曲率は、第３曲率と同じ又は第３曲率より小さくなっている（つまり、Ｒ４≧Ｒ３）。さらに、図１１（ｂ）に示す断面においては、図２に示した断面と同様にして、部材３００の第２面３１４は、第１領域３１４ａ、第２領域３１４ｂ及び第３領域３１４ｃを有している。 Next, as shown in FIG. 11, the rod 200 is tubular along one direction (Z direction in FIG. 11A) so that the outer surface 212 of the rod 200 faces the second surface 314 of the member 300.
