図7には第1連結部材21が示され、図7(A)(B)(C)(D)は、この第1連結部材21の平面図、側面図、底面図、背面図である。金属板の打ち抜き及び折り曲げ品である第1連結部材21には、中心軸24の軸方向Nに離れている2個の連結部26が互いに対向して設けられ、これらの連結部26における中心軸24の軸方向Nと直交する側の第1連結部材21全体の厚さ方向の端部同士の間には、架け渡し部27が架け渡されているため、2個の連結部26は、中心軸24の軸方向Nを幅寸法とする架け渡し部27により結合されている。また、それぞれの連結部26は、中心軸24の軸方向Nと直交しかつ第1連結部材21全体の厚さ方向とも直交する方向の長さ寸法を有し、この長さ寸法は、長さ方向の両端部26A,26Bが、ドア枠2と、壁4の躯体となっている補助部材8とに達する寸法となっている。 FIG. 7 shows the first connecting member 21, and FIGS. 7 (A), (B), (C), and (D) are a plan view, a side view, a bottom view, and a rear view of the first connecting member 21. The first connecting member 21, which is a punched and bent product of a metal plate, is provided with two connecting portions 26 separated from each other in the axial direction N of the central shaft 24, and the central shaft in these connecting portions 26 is provided. Since the bridging portion 27 is bridged between the end portions in the thickness direction of the entire first connecting member 21 on the side orthogonal to the axial direction N of the 24, the two connecting portions 26 are centered. It is connected by a bridging portion 27 having an axial direction N of the shaft 24 as a width dimension. Further, each connecting portion 26 has a length dimension in a direction orthogonal to the axial direction N of the central axis 24 and also orthogonal to the thickness direction of the entire first connecting member 21, and this length dimension is a length. Both ends 26A and 26B in the direction have dimensions that reach the door frame 2 and the auxiliary member 8 that is the frame of the wall 4.

また、それぞれの連結部26の長さ方向の両端部26A,26Bのうち、補助部材8側の端部26Aには、図7(A)(C)に示されているように、中心軸24の軸方向Nと直交する方向に対して第1連結部材21の外側への傾斜角度となっているねじり角度90°-αが設けられ、このねじり角度90°-αは、2個の連結部26について互いに逆の向きのねじり角度となっており、また、ドア枠2側の端部26Bには、図7(A)(C)に示されているように、このようなねじり角度は設けられていない。そして、補助部材8側の端部26Aとドア枠2側の端部26Bとの間は、ねじり角度90°-αを少しずつ消滅するための中間部26Cとなっている。ドア枠2側の端部26Bには、中心軸24を挿通させるための挿通部として大径の第1孔28が設けられているとともに、補助部材8側の端部26Aには、図4で示した結合具25を挿入するための小径の第2孔29が設けられている。また、それぞれの連結部26には、上述のねじり角度90°-αが存在している補助部材8側の端部26Aの範囲において、図19及び図20で後述するタッピングビスとなっている結合具50,51を挿入するための第3孔30も設けられている。 Further, of the both end portions 26A and 26B of the connecting portions 26 in the length direction, the end portions 26A on the auxiliary member 8 side have a central shaft 24 as shown in FIGS. 7A and 7C. A twist angle of 90 ° -α, which is an inclination angle to the outside of the first connecting member 21 with respect to a direction orthogonal to the axial direction N of the above, is provided, and this twist angle of 90 ° -α is the two connecting portions. The twist angles of 26 are opposite to each other, and the end 26B on the door frame 2 side is provided with such a twist angle as shown in FIGS. 7 (A) and 7 (C). Not done. Then, between the end portion 26A on the auxiliary member 8 side and the end portion 26B on the door frame 2 side, there is an intermediate portion 26C for gradually extinguishing the twist angle 90 ° -α . The end 26B on the door frame 2 side is provided with a large-diameter first hole 28 as an insertion portion for inserting the central shaft 24, and the end 26A on the auxiliary member 8 side is shown in FIG. A second hole 29 having a small diameter for inserting the indicated coupling tool 25 is provided. Further, in the range of the end portion 26A on the auxiliary member 8 side in which the above-mentioned twist angle 90 ° -α exists in each connecting portion 26, the coupling is a tapping screw described later in FIGS. 19 and 20. A third hole 30 for inserting the tools 50 and 51 is also provided.

さらに、架け渡し部27には長孔31が設けられ、連結部26の長さ方向に長くなっているこの長孔31は、架け渡し部27の強度を低下させるためにこの架け渡し部27に形成された強度低下部となっている。 Further, the connecting portion 27 is provided with a long hole 31, and the long hole 31 which is elongated in the length direction of the connecting portion 26 is provided in the connecting portion 27 in order to reduce the strength of the connecting portion 27. It is a formed strength-reducing part.

以上のように第1連結部材21は、2個の連結部26と、これらの連結部26に架け渡された架け渡し部27とにより形成された全体形状が略コの字状のものとなっているが、2個の連結部26におけるそれぞれの補助部材8側の端部26Aでの形状は、上述したねじり角度90°-αのために、第1連結部材21の外側へ開いた、これを言い換えると、中心軸24の軸方向Nの外側へ開いたハの字状となっている。 As described above, the first connecting member 21 has a substantially U-shape as a whole formed by the two connecting portions 26 and the connecting portion 27 bridged to these connecting portions 26. However, the shape of the two connecting portions 26 at the end portion 26A on the side of each auxiliary member 8 is open to the outside of the first connecting member 21 due to the above-mentioned twist angle of 90 ° -α . In other words, it has a C-shape that opens outward in the axial direction N of the central axis 24.

図8には、図4の結合具25により連結部26の補助部材8側の端部26Aを補助部材8に結合するために、それぞれの補助部材8側の端部26Aに、中心軸24の軸方向Nにおける互いに逆の向きの荷重Wが作用したときを示している。このような荷重Wがそれぞれの補助部材8側の端部26Aに作用すると、これらの補助部材8側の端部26Aの図7で示したねじり角度90°-αは減少又は消滅するとともに、架け渡し部27には、荷重Wの影響により、この架け渡し部27の厚さ方向(第1連結部材21全体の厚さ方向)のうち、第1連結部材21の外側へ突出する方向への湾曲等の変形が生じ、また、補助部材8側の端部26Aに中間部26Cを介して接続されているそれぞれのドア枠2側の端部26Bには、荷重Wの影響により、中心軸24の軸方向Nと直交する方向に対して第1連結部材21の内側への傾斜角度となったねじり角度90°-βが生じ、このねじり角度90°-βは、これらのドア枠2側の端部26Bについて、互いに逆の方向へのねじり角度となる。 In FIG. 8, in order to connect the end portion 26A on the auxiliary member 8 side of the connecting portion 26 to the auxiliary member 8 by the coupling tool 25 of FIG. 4, the central shaft 24 is attached to each end portion 26A on the auxiliary member 8 side. It shows the time when the load W in the opposite direction in the axial direction N acts. When such a load W acts on the end portion 26A on the side of each auxiliary member 8, the twist angle 90 ° -α shown in FIG. 7 of the end portion 26A on the side of each auxiliary member 8 decreases or disappears, and is hung. Due to the influence of the load W, the transfer portion 27 is curved in the thickness direction of the bridge portion 27 (the thickness direction of the entire first connecting member 21) so as to project outward from the first connecting member 21. The end 26B on the door frame 2 side, which is connected to the end 26A on the auxiliary member 8 side via the intermediate portion 26C, has a central shaft 24 due to the influence of the load W. A twist angle of 90 ° -β , which is an inward tilt angle of the first connecting member 21, is generated with respect to a direction orthogonal to the axial direction N, and this twist angle of 90 ° -β is the end on the door frame 2 side. The twist angle of the portion 26B is opposite to each other.

これにより、第1連結部材21の全体では、2個の連結部26におけるそれぞれのドア枠2側の端部26Bの形状が、ねじり角度90°-βのために、第1連結部材21の内側へ閉じた逆ハの字状となる。 As a result, in the whole of the first connecting member 21, the shape of the end portion 26B on the door frame 2 side of each of the two connecting portions 26 is inside the first connecting member 21 because the twist angle is 90 ° -β . It becomes an inverted C shape closed to.

なお、架け渡し部27には、この架け渡し部27の強度を低下させるための強度低下部となっている長孔31が設けられているため、荷重Wにより架け渡し部27は大きく上述したように湾曲等の変形を行いやすくなっており、このため、補助部材8側の端部26Aのねじり角度90°-αの減少又は消滅と、ドア枠2側の端部26Bにおけるねじり角度90°-βの発生も、一層確実に生ずるようになっている。 Since the bridging portion 27 is provided with an elongated hole 31 which is a strength reducing portion for reducing the strength of the bridging portion 27, the bridging portion 27 is largely as described above due to the load W. Therefore, the twist angle 90 ° -α of the end 26A on the auxiliary member 8 side is reduced or disappeared, and the twist angle 90 ° -at the end 26B on the door frame 2 side is reduced or disappeared. The generation of β is also becoming more reliable.

図9には、第2連結部材22が示され、図9(A)(B)は、この第2連結部材22の側面図、背面図である。第1連結部材21と同様に、金属板の打ち抜き及び折り曲げ品である第2連結部材22にも、中心軸24の軸方向Nに離れている2個の連結部35が互いに対向して設けられ、これらの連結部35における中心軸24の軸方向Nと直交する側の第2連結部材22全体の厚さ方向の端部同士の間には、架け渡し部36が架け渡されているため、2個の連結部35は、中心軸24の軸方向Nを幅寸法とする架け渡し部36により結合されている。また、それぞれの連結部35は、中心軸24の軸方向Nと直交しかつ第2連結部材22全体の厚さ方向とも直交する方向の長さ寸法を有し、この長さ寸法は、長さ方向の両端部35A,35Bが、ドア枠2と、壁4の躯体となっている補助部材8とに達する寸法となっている。 9 shows a second connecting member 22, and FIGS. 9A and 9B are side views and rear views of the second connecting member 22. Similar to the first connecting member 21, the second connecting member 22, which is a punched and bent product of a metal plate, is also provided with two connecting portions 35 facing each other in the axial direction N of the central shaft 24. Since the bridging portion 36 is bridged between the end portions in the thickness direction of the entire second connecting member 22 on the side orthogonal to the axial direction N of the central axis 24 in these connecting portions 35. The two connecting portions 35 are connected by a bridging portion 36 having an axial direction N of the central shaft 24 as a width dimension. Further, each connecting portion 35 has a length dimension in a direction orthogonal to the axial direction N of the central axis 24 and also orthogonal to the thickness direction of the entire second connecting member 22, and this length dimension is a length. Both ends 35A and 35B in the direction have dimensions that reach the door frame 2 and the auxiliary member 8 that is the frame of the wall 4.

また、それぞれの連結部35の長さ方向の両端部35A,35Bのうち、補助部材8側の端部35Aは、ドア枠2側の端部35Bに対して第2連結部材22の内側へ少し屈曲しており、これらの端部35A,35Bのうち、ドア枠2側の端部35Bには、中心軸24を挿通させるための挿通部として大径の第1孔37が設けられているとともに、補助部材8側の端部35Aには、図4で示した結合具34を挿入するための挿通部として小径の第2孔38が設けられている。また、それぞれの連結部35には、図19及び図20で後述するように、タッピングビスとなっている結合具50,51を挿入するための第3孔39も設けられている。 Further, of the both end portions 35A and 35B in the length direction of the respective connecting portions 35, the end portion 35A on the auxiliary member 8 side is slightly inward of the second connecting member 22 with respect to the end portion 35B on the door frame 2 side. Of these end portions 35A and 35B, the end portion 35B on the door frame 2 side is provided with a large-diameter first hole 37 as an insertion portion for inserting the central shaft 24. The end portion 35A on the auxiliary member 8 side is provided with a second hole 38 having a small diameter as an insertion portion for inserting the coupling tool 34 shown in FIG. Further, each connecting portion 35 is also provided with a third hole 39 for inserting the coupling tools 50 and 51 which are tapping screws, as will be described later in FIGS. 19 and 20.

さらに、架け渡し部36における連結部35の長さ方向の両端部のうち、ドア枠2側の端部36Bには、中心軸24側へ、これを言い換えると、第1連結部材21側へ突出する突片部40が形成されている。架け渡し部36の端部36Bには、この突片部40の近接箇所において、切欠部41が設けられ、本実施形態では、この切欠部41は、突片部40の両側において、端部36Bに2個設けられている。なお、本実施形態の突片部40は、図9(B)に示されているように、架け渡し部36から第2連結部材22の厚さ方向の内側に少し屈曲して形成されている。 Further, of the both ends of the connecting portion 35 in the connecting portion 36 in the length direction, the end portion 36B on the door frame 2 side protrudes toward the central shaft 24 side, in other words, toward the first connecting member 21 side. The protruding piece portion 40 is formed. The end portion 36B of the bridging portion 36 is provided with a notch portion 41 at a position close to the projecting piece portion 40, and in the present embodiment, the notch portion 41 is provided with the end portions 36B on both sides of the projecting piece portion 40. Two are provided in. As shown in FIG. 9B, the projecting piece portion 40 of the present embodiment is formed by being slightly bent inward in the thickness direction from the bridging portion 36 to the second connecting member 22. ..

このようにして第2連結部材22に形成されている突片部40は、この突片部40に第2連結部材22全体の厚さ方向への荷重が作用したときには、この厚さ方向に折り曲げ可能となっており、この折れ曲げは、切欠部41が、突片部40の両側において、架け渡し部36の端部36Bに2個設けられていて、これらの切欠部41が、架け渡し部27における突片部40の基端部分の強度を低下させるための強度低下部となっていることにより、上記荷重が小さくても突片部40を容易に折り曲げることができるようになっている。 The projecting piece portion 40 formed on the second connecting member 22 in this way is bent in the thickness direction when a load in the thickness direction of the entire second connecting member 22 is applied to the projecting piece portion 40. This bending is possible, and two notches 41 are provided at the end 36B of the bridging portion 36 on both sides of the projecting piece 40, and these notches 41 are provided in the bridging portion. Since it is a strength reducing portion for reducing the strength of the base end portion of the protruding piece portion 40 in 27, the protruding piece portion 40 can be easily bent even if the load is small.

以上説明した第1連結部材21と、第2連結部材22と、軸受け部材23と、中心軸24とからなる第1連結具20Aは、この第1連結具20Aの正面図を示している図10と、第1連結具20Aの側面図を示している図11とに示された構造に、図3で示したドア枠2を製造する工場において組み立てられる。この組み立ては、第1連結部材21の連結部26に設けられた第1孔28と、第2連結部材22の連結部35に設けられた第1孔37とに、中心軸24を共通の挿通部材として挿通するとともに、この中心軸24をハット形状となっている軸受け部材23にも挿通し、中心軸24の両端部を軸受け部材23からの抜け止め部24Aとする加工等によって行われる。 The first connecting member 20A including the first connecting member 21, the second connecting member 22, the bearing member 23, and the central shaft 24 described above is FIG. 10 showing a front view of the first connecting member 20A. And, the structure shown in FIG. 11 showing the side view of the first connector 20A is assembled in the factory where the door frame 2 shown in FIG. 3 is manufactured. In this assembly, the central shaft 24 is commonly inserted into the first hole 28 provided in the connecting portion 26 of the first connecting member 21 and the first hole 37 provided in the connecting portion 35 of the second connecting member 22. It is inserted as a member, the central shaft 24 is also inserted into the bearing member 23 having a hat shape, and both ends of the central shaft 24 are processed to be the retaining portions 24A from the bearing member 23.

なお、本実施形態に係る中心軸24は、表面にねじ山とねじ溝による凹凸が軸方向に交互に多数形成されている雄ねじ棒である。 The central shaft 24 according to the present embodiment is a male screw rod in which a large number of irregularities due to threads and threads are alternately formed on the surface in the axial direction.

図11のS12-S12線断面図である図12には、上述のように第1連結部材21と第2連結部材22と軸受け部材23と中心軸24とにより組み立てられた第1連結具20Aの断面図が示されている。工場で組み立てられた第1連結具20Aでは、第2連結部材22に形成されている突片部40は、第1連結部材21に設けられている架け渡し部27の裏面27Aに当接している。このため、中心軸24が共通の挿通部材となっている第1連結部材21と第2連結部材22は、中心軸24で連結されたものとなっているとともに、これらの第1連結部材21と第2連結部材22は、中心軸24の軸方向Nと直交する方向に並んで平行又は略平行となっている。 FIG. 12, which is a cross-sectional view taken along the line S12-S12 of FIG. 11, shows the first connecting tool 20A assembled by the first connecting member 21, the second connecting member 22, the bearing member 23, and the central shaft 24 as described above. A cross section is shown. In the first connecting tool 20A assembled at the factory, the projecting piece portion 40 formed on the second connecting member 22 is in contact with the back surface 27A of the bridging portion 27 provided on the first connecting member 21. .. Therefore, the first connecting member 21 and the second connecting member 22 in which the central shaft 24 is a common insertion member are connected by the central shaft 24 and are connected to the first connecting member 21. The second connecting member 22 is parallel or substantially parallel to each other in a direction orthogonal to the axial direction N of the central axis 24.

このため、突片部40は、第1連結部材21と第2連結部材22を、中心軸24の軸方向Nと直交する方向に並ばせて平行又は略平行とさせるための平行手段45を構成するものとなっている。また、第1連結具20Aが、後述するように、図3で示されているドア枠2と、壁側の建材となっている補助部材8との間のすき間に挿入されるときには、この平行手段45の平行機能により、第1連結部材21と第2連結部材22を、2個の建材となっているドア枠2と補助部材8との間隔の方向と、これらのドア枠2と補助部材8のうち、ドア枠2の厚さ方向(図1及び図2で示した壁4の厚さ方向でもある。)とに直交する方向(ドア枠2の側枠部材2A,2Bに配置される第1連結具20Aでは上下方向、ドア枠2の上枠部材2Cに配置される第1連結具20Aでは左右方向)に並ばせながら平行又は略平行とさせることができるようになっている。 Therefore, the projecting piece portion 40 constitutes a parallel means 45 for arranging the first connecting member 21 and the second connecting member 22 in a direction orthogonal to the axial direction N of the central axis 24 to make them parallel or substantially parallel. It is supposed to be done. Further, when the first connecting tool 20A is inserted into the gap between the door frame 2 shown in FIG. 3 and the auxiliary member 8 which is a building material on the wall side, as will be described later, the first connecting tool 20A is parallel to the door frame 2. Due to the parallel function of the means 45, the first connecting member 21 and the second connecting member 22 are arranged in the direction of the distance between the door frame 2 and the auxiliary member 8 which are two building materials, and these door frames 2 and the auxiliary member. Of 8, the direction orthogonal to the thickness direction of the door frame 2 (which is also the thickness direction of the wall 4 shown in FIGS. 1 and 2) (arranged in the side frame members 2A and 2B of the door frame 2). The first connector 20A can be arranged in the vertical direction, and the first connector 20A arranged in the upper frame member 2C of the door frame 2 in the left-right direction) so as to be parallel or substantially parallel.

以上の第1連結具20Aは、ドア枠2を製造した工場において、図4から分かるように、ドア枠2の左右の側枠部材2A,2B及び上枠部材2Cに軸受け部材23が溶接等で結合されることにより、ドア枠2に取り付けられる。また、図3で示した第2連結具20Bは、第1連結部材21と軸受け部材23と中心軸24とからなり、したがって、第2連結具20Bは、第1連結具20Aから第2連結部材22を取り除いたものと同じ構造になっている。このようなこの第2連結具20Bも、ドア枠2の左右の側枠部材2A,2Bに軸受け部材23が溶接等で結合されることにより、工場でドア枠2に取り付けられる。 In the above first connector 20A, as can be seen from FIG. 4, in the factory where the door frame 2 is manufactured, the bearing member 23 is welded to the left and right side frame members 2A and 2B and the upper frame member 2C of the door frame 2 by welding or the like. By being combined, it is attached to the door frame 2. Further, the second connecting member 20B shown in FIG. 3 includes a first connecting member 21, a bearing member 23, and a central shaft 24. Therefore, the second connecting member 20B is a first connecting member 20A to a second connecting member. It has the same structure as the one with 22 removed. Such a second connecting tool 20B is also attached to the door frame 2 at the factory by connecting the bearing member 23 to the left and right side frame members 2A and 2B of the door frame 2 by welding or the like.

第1連結具20Aと第2連結具20Bが工場で取り付けられたドア枠2は、図1の開き戸装置が施工設置される作業現場に運ばれ、この後に、図2の壁4の図4で示した面材6が芯部材5に取り付けられる以前において、ドア枠2の左右の側枠部材2A,2Bと、図2の壁4を構成するために図3の芯部材5A,5Bに結合された補強部材7に取り付けられている補助部材8との間の左右方向の間隔に、第1連結具20A及び第2連結具20Bを挿入するとともに、ドア枠2の上枠部材2Cと、図3の芯部材5Cに結合された補強部材7に取り付けられている補助部材8との間の上下方向の間隔に、第1連結具20Aを挿入し、これにより、ドア枠2及び第1及び第2連結具20A,20Bを図1及び図2に示されている壁4の開口部4Aの内側に配置する。なお、補強部材7に補助部材8を取り付ける作業は、以上のようにしてドア枠2及び第1及び第2連結具20A,20Bを壁4の開口部4Aの内側に配置するための作業を行う直前において行われる。 The door frame 2 to which the first connecting tool 20A and the second connecting tool 20B are attached at the factory is carried to the work site where the hinged door device of FIG. 1 is installed, and after that, in FIG. 4 of the wall 4 of FIG. Before the indicated face member 6 is attached to the core member 5, it is coupled to the left and right side frame members 2A and 2B of the door frame 2 and the core members 5A and 5B of FIG. 3 to form the wall 4 of FIG. The first connecting tool 20A and the second connecting tool 20B are inserted at a distance in the left-right direction between the auxiliary member 8 attached to the reinforcing member 7, and the upper frame member 2C of the door frame 2 and FIG. 3 The first connecting tool 20A is inserted in the vertical space between the auxiliary member 8 attached to the reinforcing member 7 coupled to the core member 5C of the door frame 2 and the door frame 2 and the first and second. The connectors 20A and 20B are arranged inside the opening 4A of the wall 4 shown in FIGS. 1 and 2. The work of attaching the auxiliary member 8 to the reinforcing member 7 is the work of arranging the door frame 2 and the first and second connecting tools 20A and 20B inside the opening 4A of the wall 4 as described above. It will be done just before.

本実施形態では、以上のようにドア枠2及び第1及び第2連結具20A,20Bを壁4の開口部4Aの内側に配置する作業を行う際において、第1連結具20Aの第1連結部材21と第2連結部材22が中心軸24を中心に回動自在となっていても、ドア枠2の側枠部材2A,2Bと、芯部材5A,5Bに結合された補強部材7に取り付けられている補助部材8との間の左右方向の間隔に挿入される第1連結具20Aについては、上述した平行手段45の平行機能により、第1連結部材21と第2連結部材22とを、側枠部材2A,2Bと補強部材7との間隔である左右方向と、ドア枠2の厚さ方向とに直交する方向となっている上下方向に並ばせながら平行又は略平行とさせることができ、また、ドア枠2の上枠部材2Cと、芯部材5Cに結合された補強部材7に取り付けられている補助部材8との間の上下方向の間隔に挿入される第1連結具20Aについては、平行手段45の平行機能により、第1連結部材21と第2連結部材22とを、上枠部材2Cと補強部材7との間隔である上下方向と、ドア枠2の厚さ方向とに直交する方向となっている左右方向に並ばせながら平行又は略平行とさせることができる。 In the present embodiment, when the door frame 2 and the first and second connecting tools 20A and 20B are arranged inside the opening 4A of the wall 4 as described above, the first connecting tool 20A is connected. Even if the member 21 and the second connecting member 22 are rotatable about the central shaft 24, they are attached to the side frame members 2A and 2B of the door frame 2 and the reinforcing member 7 coupled to the core members 5A and 5B. With respect to the first connecting member 20A inserted at a distance in the left-right direction between the auxiliary member 8 and the auxiliary member 8, the first connecting member 21 and the second connecting member 22 are separated by the parallel function of the parallel means 45 described above. It can be parallel or substantially parallel while being lined up in the vertical direction, which is the direction orthogonal to the horizontal direction, which is the distance between the side frame members 2A and 2B and the reinforcing member 7, and the thickness direction of the door frame 2. Further, regarding the first connecting tool 20A inserted in the vertical distance between the upper frame member 2C of the door frame 2 and the auxiliary member 8 attached to the reinforcing member 7 coupled to the core member 5C. Due to the parallel function of the parallel means 45, the first connecting member 21 and the second connecting member 22 are orthogonal to the vertical direction, which is the distance between the upper frame member 2C and the reinforcing member 7, and the thickness direction of the door frame 2. It is possible to make them parallel or substantially parallel while arranging them in the left-right direction, which is the direction in which they are used.

このため、上述したように第1連結具20Aの第1連結部材21と第2連結部材22が中心軸24を中心に回動自在となっていて、側枠部材2A,2Bと補強部材7との左右方向の間隔や、上枠部材2Cと補強部材7との上下方向の間隔が小さくなっていても、これらの間隔に第1連結具20Aを有効に挿入することができ、この挿入作業時には、第2連結具20Bにおける第1連結部材21だけを、この第2連結具20Bの中心軸24を中心にして上向きに立てた状態にしてこの挿入作業を実施すればよいため、少ない作業者により作業性を向上させて容易かつ短時間で終了することができる。 Therefore, as described above, the first connecting member 21 and the second connecting member 22 of the first connecting tool 20A are rotatable about the central shaft 24, and the side frame members 2A and 2B and the reinforcing member 7 are used. Even if the distance between the left and right directions and the vertical distance between the upper frame member 2C and the reinforcing member 7 is small, the first connector 20A can be effectively inserted into these spaces, and during this insertion work, the first connector 20A can be effectively inserted. Since it is sufficient to carry out this insertion work with only the first connecting member 21 in the second connecting tool 20B standing upward with respect to the central axis 24 of the second connecting tool 20B, a small number of workers are required. Workability can be improved and it can be completed easily and in a short time.

上述したようにして複数個の第1連結具20Aを側枠部材2A,2Bと補強部材7との左右方向の間隔、及び上枠部材2Cと補強部材7との上下方向の間隔に挿入した後に、作業者は、それぞれの第1連結具20Aにおける第1連結部材21と第2連結部材22のうち、少なくとも一方の連結部材を他方の連結部材に対して中心軸24を中心に側枠部材2A,2B側や上枠部材2C側とは反対側に回動させる作業を行う。この回動作業は、例えば、第1連結部材21の図7で示した第2孔29や第3孔30、第2連結部材22の図9で示した第2孔38や第3孔39に工具等を挿入することにより実施できる。 After inserting the plurality of first connecting tools 20A into the lateral distance between the side frame members 2A and 2B and the reinforcing member 7 and the vertical spacing between the upper frame member 2C and the reinforcing member 7 as described above. , The worker attaches at least one of the first connecting member 21 and the second connecting member 22 in each first connecting member 20A to the other connecting member with respect to the side frame member 2A centering on the central shaft 24. , Perform the work of rotating to the side opposite to the 2B side and the upper frame member 2C side. This rotation work is performed, for example, in the second hole 29 and the third hole 30 shown in FIG. 7 of the first connecting member 21, and in the second hole 38 and the third hole 39 shown in FIG. 9 of the second connecting member 22. It can be carried out by inserting a tool or the like.

図14は、この回動作業が実施された後における第1連結具20Aの側面図を示している図13のS14-S14線断面図である。この図14に示されているように、上述の回動作業が行われると、第2連結部材22に設けられていて、第1連結部材21の架け渡し部27の裏面27Aに当接していた突片部40は、作業者による回動作業による荷重により、第2連結部材22の架け渡し部36との接続箇所から折れ曲がり、これにより、平行手段45の平行機能が消滅する。このため、複数個の第1連結具20Aのうち、側枠部材2A,2Bと補強部材7との間隔に挿入された第1連結具20Aについては、第1連結部材21と第2連結部材22とを、図10の二点鎖線で示されている第1連結部材21と第2連結部材22から分かるように、側枠部材2A,2Bと補強部材7との間隔の方向である左右方向Mに対する傾き角度θ1,θ2が互いに逆の向きの角度となるように中心軸24を中心に回動させることにより、これらの第1及び第2連結部材21,22における2個の連結部26,35の図7及び図9で示した補助部材8側の端部26A同士の間及び端部35A同士の間に補助部材8に挿入することができる(図15を参照)。また、上枠部材2Cと補助部材8との間隔に挿入された第1連結具20Aについては、第1連結部材21と第2連結部材22とを、上枠部材2Cと補強部材7との間隔の方向である上下方向に対する傾き角度が互いに逆の向きの角度となるように中心軸24を中心に回動させて、これらの第1及び第2連結部材21,22における2個の連結部26,35の補助部材8側の端部26A同士の間及び端部35A同士の間に補助部材8に挿入することができる。 FIG. 14 is a cross-sectional view taken along the line S14-S14 of FIG. 13 showing a side view of the first connector 20A after the rotation work is performed. As shown in FIG. 14, when the above-mentioned rotation work is performed, the second connecting member 22 is provided and is in contact with the back surface 27A of the connecting portion 27 of the first connecting member 21. The projecting piece portion 40 bends from the connection portion of the second connecting member 22 with the connecting portion 36 due to the load due to the rotation work by the operator, whereby the parallel function of the parallel means 45 disappears. Therefore, among the plurality of first connecting members 20A, the first connecting member 20A inserted at the distance between the side frame members 2A and 2B and the reinforcing member 7 is the first connecting member 21 and the second connecting member 22. As can be seen from the first connecting member 21 and the second connecting member 22 shown by the two-dot chain line in FIG. 10, the left-right direction M which is the direction of the distance between the side frame members 2A and 2B and the reinforcing member 7. By rotating the central axis 24 around the central axis 24 so that the tilt angles θ1 and θ2 with respect to each other are opposite to each other, the two connecting portions 26 and 35 in these first and second connecting members 21 and 22 are formed. Can be inserted into the auxiliary member 8 between the end portions 26A on the auxiliary member 8 side and between the end portions 35A shown in FIGS. 7 and 9 (see FIG. 15). Further, regarding the first connecting tool 20A inserted at the distance between the upper frame member 2C and the auxiliary member 8, the first connecting member 21 and the second connecting member 22 are separated from each other, and the distance between the upper frame member 2C and the reinforcing member 7 is provided. The two connecting portions 26 in these first and second connecting members 21 and 22 are rotated around the central axis 24 so that the tilt angles with respect to the vertical direction, which is the direction of the above, are opposite to each other. , 35 can be inserted into the auxiliary member 8 between the ends 26A on the auxiliary member 8 side and between the end portions 35A.

このため、それぞれの第1連結具20Aにおいて、第1連結部材21は、側枠部材2A,2Bと補助部材8との間隔の方向や、上枠部材2Cと補助部材8との間隔の方向に対する傾き角度をなすものとなるとともに、第2連結部材22は、側枠部材2A,2Bと補助部材8との間隔の方向や、上枠部材2Cと補助部材8との間隔の方向に対する傾き角度が、第1連結部材の傾き角度とは逆向きの傾き角度をなすものとなる。 Therefore, in each of the first connecting tools 20A, the first connecting member 21 relates to the direction of the distance between the side frame members 2A and 2B and the auxiliary member 8 and the direction of the distance between the upper frame member 2C and the auxiliary member 8. In addition to forming an inclination angle, the second connecting member 22 has an inclination angle with respect to the direction of the distance between the side frame members 2A and 2B and the auxiliary member 8 and the direction of the distance between the upper frame member 2C and the auxiliary member 8. , The tilt angle is opposite to the tilt angle of the first connecting member.

なお、これらの第1連結具20Aにおいて、前述したように、第2連結部材22には、この第2連結部材22に設けられている突片部40の両側において、強度低下部となっている切欠部41が2個形成されているため、突片部40を、第2連結部材22の架け渡し部36との接続箇所から折り曲げるための上述の回動作業の荷重が小さくても、作業者は、突片部40をより確実に折り曲げることができる。 In these first connecting tools 20A, as described above, the second connecting member 22 has strength reducing portions on both sides of the projecting piece portions 40 provided on the second connecting member 22. Since the two cutout portions 41 are formed, even if the load of the above-mentioned rotation work for bending the projecting piece portion 40 from the connection portion of the second connecting member 22 with the connecting portion 36 is small, the operator Can more reliably bend the projecting piece portion 40.

また、本実施形態では、第1連結具20Aの構成部材となっている中心軸24は、この第1連結具20Aの第1連結部材21と第2連結部材22とを回動自在とするために、これらの第1連結部材21と第2連結部材22とに共通して挿通された挿通部材となっているため、これらの第1連結部材21と第2連結部材22を回動自在とする中心軸を、これらの第1連結部材21と第2連結部材22に個別に設けた場合と比較すると、第1連結具20Aを構成する部材点数の削減を図ることができ、これにより、構造の簡単化及び製造コストの安価化を達成できる。 Further, in the present embodiment, the central shaft 24, which is a constituent member of the first connecting tool 20A, makes the first connecting member 21 and the second connecting member 22 of the first connecting tool 20A rotatable. In addition, since the insertion member is inserted in common with the first connecting member 21 and the second connecting member 22, the first connecting member 21 and the second connecting member 22 are rotatable. Compared with the case where the central axis is individually provided on the first connecting member 21 and the second connecting member 22, the number of members constituting the first connecting member 20A can be reduced, whereby the structure can be reduced. Simplification and reduction of manufacturing cost can be achieved.

図15には、上述したように第1連結具20Aの第1及び第2連結部材21,22における2個の連結部26,35の補助部材8側の端部26A同士の間及び端部35A同士の間に補助部材8が挿入された状態が示されている。 In FIG. 15, as described above, between the ends 26A on the auxiliary member 8 side of the two connecting portions 26 and 35 in the first and second connecting members 21 and 22 of the first connecting tool 20A and at the end portion 35A. A state in which the auxiliary member 8 is inserted between the two is shown.

前述した作業を行った後に、作業者は、第1連結具20Aにおける第1連結部材21のそれぞれの補助部材8側の端部を、図4及び図13で示されている2個の結合具25を、第1連結部材21の連結部26に設けられた図7の第2孔29に挿入して補助部材8にねじ込むことにより、図16及び図17に示されているように補助部材8に結合し、また、第2連結部材22のそれぞれの補助部材8側の端部も、図4及び図13で示されている2個の結合具34を、第2連結部材22の連結部35に設けられた図9の第2孔38に挿入して補助部材8にねじ込むことにより、図16及び図17に示されているように補助部材8に結合する。 After performing the above-mentioned work, the operator attaches the ends of the first connecting member 21 on the side of the auxiliary member 8 of the first connecting member 20A to the two coupling members shown in FIGS. 4 and 13. By inserting 25 into the second hole 29 of FIG. 7 provided in the connecting portion 26 of the first connecting member 21 and screwing it into the auxiliary member 8, the auxiliary member 8 is screwed into the auxiliary member 8 as shown in FIGS. 16 and 17. Also, the ends of the second connecting member 22 on the side of the auxiliary member 8 also have the two coupling members 34 shown in FIGS. 4 and 13 attached to the connecting portion 35 of the second connecting member 22. By inserting it into the second hole 38 of FIG. 9 and screwing it into the auxiliary member 8, it is coupled to the auxiliary member 8 as shown in FIGS. 16 and 17.

また、作業者は、図3に示されているように、ドア枠2の左右の側枠部材2A,2Bの最下部に配置されている2個の第2連結具20Bのそれぞれにおいて、第1連結部材21を中心軸24を中心に回動させて、この第1連結部材21についての前述した左右方向Mに対する傾き角度を、第1連結具20Aの第1連結部材21についての傾き角度θ1と同じ又は略同じにして、この第1連結部材21の補助部材8側の端部を、図4及び図13で示した2個の結合具25と同様の結合具により、補助部材8に結合する。 Further, as shown in FIG. 3, the operator can use the first of the two second connecting tools 20B arranged at the lowermost portions of the left and right side frame members 2A and 2B of the door frame 2. The connecting member 21 is rotated around the central axis 24, and the tilt angle of the first connecting member 21 with respect to the above-mentioned left-right direction M is defined as the tilt angle θ1 of the first connecting member 20A with respect to the first connecting member 21. In the same or substantially the same manner, the end portion of the first connecting member 21 on the auxiliary member 8 side is coupled to the auxiliary member 8 by the same coupling tool as the two coupling tools 25 shown in FIGS. 4 and 13. ..

なお、これらの第2連結具20Bを、第1連結部材21が用いられていて、第2連結部材22が用いられていないものとしている理由は、第1連結部材21の下側に配置される第2連結部材22を省略することにより、第2連結具20Bを左右の側枠部材2A,2Bの最下部の箇所に第2連結具20Bを有効に配置できるようにするためである。 The reason why these second connecting members 20B are such that the first connecting member 21 is used and the second connecting member 22 is not used is arranged below the first connecting member 21. By omitting the second connecting member 22, the second connecting member 20B can be effectively arranged at the lowermost portion of the left and right side frame members 2A and 2B.

前述した結合具25,34による結合作業を行うと、ドア枠2はそれぞれの補助部材8に、複数個の第1連結具20Aでは、第1連結部材21の2個の連結部26と、第2連結部材22の2個の連結部35とを介して、また、2個の第2連結具20Bでは、第1連結部材21の2個の連結部35とを介して、それぞれ連結されたことになる。そして、この連結作業は、側枠部材2A,2Bと補強部材7との間隔に挿入された第1連結具20Aについては、第1連結部材21と第2連結部材22とを、側枠部材2A,2Bと補強部材7との間隔の方向である左右方向Mに対する傾き角度θ1、θ2を互いに逆の向きの角度とさせた姿勢にして行っているため、ドア枠2は、補助部材8に対して上下方向に不動状態となって連結されていることになる。また、上記連結作業は、上枠部材2Cと補助部材8との間隔に挿入された第1連結具20Aについては、第1連結部材21と第2連結部材22とを、上枠部材2Cと補強部材7との間隔の方向である上下方向に対する傾き角度を互いに逆の向きの角度とさせた姿勢にして行っているため、ドア枠2が、補助部材8に対して左右方向にも不動状態となって連結されていることになる。 When the joining work by the connecting tools 25 and 34 described above is performed, the door frame 2 is attached to each auxiliary member 8, and in the plurality of first connecting tools 20A, the two connecting portions 26 of the first connecting member 21 and the second connecting portion 26. The two connecting members 22 were connected to each other via the two connecting portions 35, and the two second connecting members 20B were connected to each other via the two connecting portions 35 of the first connecting member 21. become. Then, in this connecting work, for the first connecting tool 20A inserted at the distance between the side frame members 2A and 2B and the reinforcing member 7, the first connecting member 21 and the second connecting member 22 are connected to the side frame member 2A. , 2B and the reinforcing member 7 are oriented so that the tilt angles θ1 and θ2 with respect to the left-right direction M, which is the direction of the distance between the two B and the reinforcing member 7, are opposite to each other. It is in an immobile state in the vertical direction and is connected. Further, in the above-mentioned connecting work, for the first connecting tool 20A inserted at the distance between the upper frame member 2C and the auxiliary member 8, the first connecting member 21 and the second connecting member 22 are reinforced with the upper frame member 2C. Since the tilt angle with respect to the vertical direction, which is the direction of the distance from the member 7, is set to an angle opposite to each other, the door frame 2 is in an immovable state in the left-right direction with respect to the auxiliary member 8. It will be connected.

また、図16及び図17に示されているように、第1連結具20Aにおける第1連結部材21のそれぞれの補助部材8側の端部を、図4及び図13で示されている2個の結合具25を、第1連結部材21のそれぞれの連結部26に設けられた図7の第2孔29に挿入することにより、補助部材8に結合したときには、図8で説明したように、それぞれの連結部26の補助部材8側の端部26Aには、結合具25からの荷重Wが作用する。このため、これらの補助部材8側の端部26Aに存在していたねじり角度90°-αが、荷重Wのために減少又は消滅するとともに、補助部材8側の端部26Aとは反対側の端部であるドア枠2側の端部26Bには、前述したようにねじり角度90°-βが生ずることになる。 Further, as shown in FIGS. 16 and 17, two ends of the first connecting member 21 on the first connecting member 20A on the side of the auxiliary member 8 are shown in FIGS. 4 and 13. When the coupling tool 25 is coupled to the auxiliary member 8 by inserting the coupling tool 25 into the second hole 29 of FIG. 7 provided in each connecting portion 26 of the first connecting member 21, as described with reference to FIG. The load W from the coupling tool 25 acts on the end portion 26A on the auxiliary member 8 side of each connecting portion 26. Therefore, the twist angle 90 ° -α existing at the end portion 26A on the auxiliary member 8 side is reduced or disappears due to the load W, and is on the opposite side of the end portion 26A on the auxiliary member 8 side. As described above, a twist angle of 90 ° -β is generated at the end portion 26B on the door frame 2 side, which is the end portion.

図18には、このようなねじり角度90°-βが第1連結部材21のそれぞれの連結部26のドア枠2側の端部26Bに生ずることを示したこの端部26Bの拡大断面図である。この図18に示されているように、それぞれの第1連結部材21の連結部26のドア枠2側の端部26Bにねじり角度90°-βが生ずると、このねじり角度90°-βは、中心軸24の軸方向と直交する方向に対して傾斜した角度となるため、この中心軸24を挿通させるためにドア枠2側に端部26Bに設けられた挿通部となっている孔28も、中心軸24の軸方向Nに対して傾斜することになる。このため、孔28の角部28Aは、中心軸24の表面に係止することになり、これを言い換えると、中心軸24は、孔28の角部28Aが係止する被係止部材となり、この被係止部材への孔28の係止により、第1連結部材21が構成部材となっている第1連結具20Aは、中心軸24の軸方向Nであるドア枠2の厚さ方向に不動状態となる。このため、ドア枠2は、躯体側建材となっている補助部材8に対してドア枠2の厚さ方向に不動状態となって連結されることになる。 FIG. 18 is an enlarged cross-sectional view of the end portion 26B showing that such a twist angle 90 ° -β occurs at the end portion 26B on the door frame 2 side of each connecting portion 26 of the first connecting member 21. be. As shown in FIG. 18, when a twist angle of 90 ° -β occurs at the end 26B of the connecting portion 26 of each first connecting member 21 on the door frame 2 side, the twist angle 90 ° -β becomes. , Since the angle is inclined with respect to the direction orthogonal to the axial direction of the central axis 24, the hole 28 which is an insertion portion provided at the end 26B on the door frame 2 side for inserting the central axis 24. Will also be tilted with respect to the axial direction N of the central axis 24. Therefore, the corner portion 28A of the hole 28 is locked to the surface of the central shaft 24, in other words, the central shaft 24 becomes a locked member to which the corner portion 28A of the hole 28 is locked. By locking the hole 28 to the locked member, the first connecting tool 20A in which the first connecting member 21 is a constituent member is in the thickness direction of the door frame 2 which is the axial direction N of the central shaft 24. It becomes immobile. Therefore, the door frame 2 is connected to the auxiliary member 8 which is the building material on the skeleton side in an immovable state in the thickness direction of the door frame 2.

特に、本実施形態の被係止部材となっている中心軸24は、前述したように、表面にねじ山とねじ溝による凹凸が軸方向に交互に多数形成されている雄ねじ棒であるため、孔28の角部28Aは、中心軸24の表面に一層確実に係止することになり、これにより、ドア枠2を、補助部材8に対してドア枠2の厚さ方向に一層確実に不動状態となって連結することができる。 In particular, the central shaft 24, which is the locked member of the present embodiment, is a male screw rod having a large number of irregularities due to threads and threads alternately formed on the surface in the axial direction, as described above. The corner portion 28A of the hole 28 is more reliably locked to the surface of the central shaft 24, whereby the door frame 2 is more reliably immovable with respect to the auxiliary member 8 in the thickness direction of the door frame 2. It can be connected in a state.

また、本実施形態では、第1及び第2連結部材21,22が前述した結合具25,34により結合される補助部材8は、図4で示した位置決め部材10により、補強部材7にドア枠2の厚さ方向における所定位置に位置決めされて取り付けられているため、孔28の角部28Aが中心軸24の表面に係止することにより、ドア枠2は、このドア枠2の厚さ方向の所定位置に位置決めされて配置されることになる。 Further, in the present embodiment, the auxiliary member 8 to which the first and second connecting members 21 and 22 are connected by the above-mentioned coupling tools 25 and 34 is attached to the door frame to the reinforcing member 7 by the positioning member 10 shown in FIG. Since the door frame 2 is positioned and attached at a predetermined position in the thickness direction of 2, the corner portion 28A of the hole 28 is locked to the surface of the central shaft 24, so that the door frame 2 is placed in the thickness direction of the door frame 2. Will be positioned and placed in a predetermined position.

また、本実施形態では、上述したように第1連結部材21の2個の連結部26のそれぞれの補助部材8側の端部26Aに、図4の結合具25による図8の荷重Wが作用したときには、第1連結部材21に設けられている架け渡し部27に、図8で説明したように、この架け渡し部27の厚さ方向のうち、第1連結部材21の外側へ突出する方向への湾曲等の変形が生じるとともに、第1連結部材21のそれぞれのドア枠2側の端部26Bにねじり角度90°-βが生ずることになる。本実施形態では、架け渡し部27には、架け渡し部27の強度を低下させるための強度低下部となっている長孔31が設けられているため、荷重Wにより、架け渡し部27の湾曲等の変形は一層確実に生じることになり、これにより、ドア枠2側の端部26Bのねじり角度90°-βも一層確実に生じることになる。 Further, in the present embodiment, as described above, the load W of FIG. 8 by the coupling tool 25 of FIG. 4 acts on the end portion 26A on the auxiliary member 8 side of each of the two connecting portions 26 of the first connecting member 21. At that time, as described with reference to FIG. 8, the connecting portion 27 provided in the first connecting member 21 protrudes to the outside of the first connecting member 21 in the thickness direction of the connecting portion 27. Along with the deformation such as bending to, a twist angle of 90 ° -β is generated at the end portion 26B on the door frame 2 side of each of the first connecting members 21. In the present embodiment, since the bridging portion 27 is provided with an elongated hole 31 which is a strength reducing portion for reducing the strength of the bridging portion 27, the bridging portion 27 is curved due to the load W. Deformation such as, etc. will occur more reliably, and as a result, the twist angle 90 ° -β of the end portion 26B on the door frame 2 side will also occur more reliably.

以上説明した実施形態では、第1連結具20Aの第1及び第2連結部材21,22の2個の連結部26,35における補助部材8側の端部26A,35Aを補助部材8に結合すするためのそれぞれ2個ずつとなっている結合具25,34は、図16及び図17に示されているように、互いに中心軸24の軸方向Nにおける反対側に配置されていて、これらの補助部材8側の端部26A,35Aを補助部材8に結合するために、中心軸24の軸方向Nにおける互いに逆の向きとなっていた。 In the embodiment described above, the ends 26A and 35A on the auxiliary member 8 side of the two connecting portions 26 and 35 of the first and second connecting members 21 and 22 of the first connecting tool 20A are connected to the auxiliary member 8. As shown in FIGS. 16 and 17, the coupling tools 25 and 34, which are two each, are arranged on opposite sides of the central axis 24 in the axial direction N. In order to connect the ends 26A and 35A on the auxiliary member 8 side to the auxiliary member 8, the directions were opposite to each other in the axial direction N of the central axis 24.

図19及び図20で示した実施形態では、第1連結具20Aの第1連結部材21の2個の連結部26における補助部材8側の端部26Aを補助部材8に結合するために、上述の1個の結合具25と、別の1個の結合具50とが用いられている。これらの結合具25,50は、中心軸24の軸方向Nにおける同じ側に配置されて、この軸方向Nにおける同じ向きとなっているとともに、これらの結合具25,50のうち、結合具50は、図19に示されているように、2個の連結部26D,26Eのうち、中心軸24の軸方向Nにおける結合具25,50が配置されている上記同じ側とは反対側に配置されている連結部26Dを、上記同じ側に配置されている連結部26Eの側へ引き寄せるための結合具となっている。また、第2連結部材22の2個の連結部35における補助部材8側の端部35Aを補助部材8に結合するために、上述の1個の結合具34と、別の1個の結合具51とが用いられており、これらの結合具34,51も、中心軸24の軸方向Nにおける同じ側に配置されて、この軸方向Nにおける同じ向きとなっているとともに、これらの結合具34,51のうち、結合具51は、2個の連結部35のうち、中心軸24の軸方向Nにおける結合具34,51が配置されている上記同じ側とは反対側に配置されている連結部35Dを、上記同じ側に配置されている連結部35Eの側へ引き寄せるための結合具となっている。 In the embodiment shown in FIGS. 19 and 20, in order to connect the end portion 26A on the auxiliary member 8 side of the two connecting portions 26 of the first connecting member 21 of the first connecting tool 20A to the auxiliary member 8 described above. One binder 25 and another coupler 50 are used. These couplers 25 and 50 are arranged on the same side in the axial direction N of the central axis 24 and have the same orientation in the axial direction N, and among these couplers 25 and 50, the coupler 50 Is arranged on the side of the two connecting portions 26D and 26E opposite to the same side on which the couplers 25 and 50 are arranged in the axial direction N of the central axis 24, as shown in FIG. It is a coupling tool for pulling the connecting portion 26D to the side of the connecting portion 26E arranged on the same side. Further, in order to connect the end portion 35A on the auxiliary member 8 side of the two connecting portions 35 of the second connecting member 22 to the auxiliary member 8, the above-mentioned one coupling tool 34 and another coupling tool 34 are used. 51 is used, and these coupling tools 34 and 51 are also arranged on the same side in the axial direction N of the central axis 24 and have the same orientation in the axial direction N, and these coupling tools 34 are also used.
