Description

連結機構Coupling mechanism
　本発明は、複数のケーブルを連結する連結機構に関する。 The present invention relates to a connecting mechanism that connects a plurality of cables.
　従来、操作部材に接続されたケーブルと作動部材に接続されたケーブルとを連結し、それら複数のケーブルを介して操作部材による操作力を作動部材へ伝達する機構として、例えば、図５（ａ）～（ｃ）に示される連結機構１００が用いられている。この連結機構１００は、一方側に延びるインナーケーブル１０１ａのケーブルエンド１０２ａと他方側に延びるインナーケーブル１０１ｂのケーブルエンド１０２ｂとが、一方側に延びるインナーケーブル１０１ａ又は他方側に延びるインナーケーブル１０１ｂから、他方側に延びるインナーケーブル１０１ｂ又は一方側に延びるインナーケーブル１０１ａへと操作力が伝達されるようにジョイントピース１０３に取り付けられている。そして、そのジョイントピース１０３は、インナーケーブル１０１ａとインナーケーブル１０１ｂとを連結した状態で、ジョイントピース１０３がスライド可能で、連結状態が解除されないようにケース１０４内に収容される。ジョイントピース１０３が収容されるケース１０４は、ケース１０４のうち、ジョイントピース１０３のスライド方向における一端側（図５（ａ）中、ケース１０４の右側の端部）が開口している。 Conventionally, as a mechanism for connecting a cable connected to an operation member and a cable connected to an operation member and transmitting an operation force by the operation member to the operation member via the plurality of cables, for example, FIG. A coupling mechanism 100 shown in (c) is used. In this connecting mechanism 100, the cable end 102a of the inner cable 101a extending to one side and the cable end 102b of the inner cable 101b extending to the other side are connected from the inner cable 101a extending to one side or the inner cable 101b extending to the other side to the other. It is attached to the joint piece 103 so that the operating force is transmitted to the inner cable 101b extending to the side or the inner cable 101a extending to the one side. The joint piece 103 is accommodated in the case 104 so that the joint piece 103 can be slid in a state where the inner cable 101a and the inner cable 101b are connected, and the connected state is not released. In the case 104 in which the joint piece 103 is accommodated, one end side of the case 104 in the sliding direction of the joint piece 103 (the right end portion of the case 104 in FIG. 5A) is open.
　連結機構１００でのインナーケーブル１０１ａ、１０１ｂの組み付け方法は、図５（ａ）に示されるように、まず、片方の端部にケーブルエンド１０２ａが形成されたインナーケーブル１０１ａについて、ジョイントピース１０３を挿入可能な開口を一端に有する角筒状のケース１０４の該開口から、ケーブルエンドが形成されていない方のインナーケーブル１０１ａの端部が、ケーブルエンド１０２ａが形成されている方の端部がケース１０４の開口側となるように、ケース１０４に挿通される。片方の端部にケーブルエンド１０２ｂが形成されたインナーケーブル１０１ｂについても、図５（ａ）に示されるように、インナーケーブル１０１ａと同様の方法でケース１０４の一端側の開口を閉鎖するキャップ１０５に挿通される。つぎに、図５（ｂ）に示されるように、ケース１０４の外部において、ジョイントピース１０３に複数のインナーケーブル１０１ａ、１０１ｂのケーブルエンド１０２ａ、１０２ｂを取り付ける。その後、ケース１０４の開口から、ジョイントピース１０３をケース１０４内に挿入して、図５（ｃ）に示されるように、ケース１０４の開口をキャップ１０５により閉じて、ジョイントピース１０３をケース１０４内に収容している。なお、インナーケーブル１０１ａのケーブルエンドが形成されていない側（図５（ｃ）中、左側）の端部には、その後、ケーブルエンド１０６が鋳込みにより形成される（インナーケーブル１０１ｂの右側の端部も同様）。 As shown in FIG. 5A, the method of assembling the inner cables 101a and 101b in the coupling mechanism 100 is as follows. First, the joint piece 103 is inserted into the inner cable 101a in which the cable end 102a is formed at one end. From the opening of the rectangular tube-shaped case 104 having a possible opening at one end, the end of the inner cable 101a where the cable end is not formed is the case 104 and the end where the cable end 102a is formed is the case 104. The case 104 is inserted so as to be on the opening side. For the inner cable 101b having the cable end 102b formed on one end, as shown in FIG. 5A, the cap 105 that closes the opening on one end side of the case 104 in the same manner as the inner cable 101a. It is inserted. Next, as illustrated in FIG. 5B, the cable ends 102 a and 102 b of the plurality of inner cables 101 a and 101 b are attached to the joint piece 103 outside the case 104. Thereafter, the joint piece 103 is inserted into the case 104 from the opening of the case 104, and the opening of the case 104 is closed by the cap 105 as shown in FIG. Contained. A cable end 106 is then formed by casting at the end of the inner cable 101a where the cable end is not formed (left side in FIG. 5C) (the right end of the inner cable 101b). The same).
　このようなジョイントピース１０３は、インナーケーブル１０１ａ、１０１ｂが操作されるとケース１０４内でスライドするため、操作力低減や部材間の摩耗を防止するために摺動抵抗を下げることが望ましい。接触面積を減らして摺動抵抗を下げるためや軽量化のために、ジョイントピース１０３の上面側から底面側に向かって（図５（ｂ）中、紙面奥行方向に向かって）貫通させた貫通孔がジョイントピース１０３の長軸方向に亘って設けられ、ケーブルエンド１０２ａ、１０２ｂを係止するためのケーブルエンドの係止部１０３ａ（図５（ｂ）参照）が前記貫通孔の内壁となるように、ジョイントピース１０３の端部に設けられた構造とされている場合がある。 Since such a joint piece 103 slides in the case 104 when the inner cables 101a and 101b are operated, it is desirable to reduce the sliding resistance in order to reduce the operating force and prevent wear between members. A through-hole penetrating from the upper surface side of the joint piece 103 toward the bottom surface side (in the depth direction of FIG. 5B) in order to reduce the contact area and reduce the sliding resistance or to reduce the weight. Is provided over the major axis direction of the joint piece 103 so that the cable end locking portion 103a (see FIG. 5B) for locking the cable ends 102a and 102b becomes the inner wall of the through hole. In some cases, the structure is provided at the end of the joint piece 103.
　このような貫通構造を有するジョイントピース１０３は、上面及び底面に開口を有するために軽量であってケース１０４との接触面積も少なくされ、摺動抵抗が低くされている。しかし、その反面、上面から底面へ向けてケーブルエンド１０２ａ、１０２ｂを挿入すると、ケーブルエンド１０２ａ、１０２ｂが底面の開口を突き抜けてしまうことがある。そのため、ケーブルエンド１０２ａ、１０２ｂをジョイントピース１０３の係止位置まで案内した後に、他のケーブルエンド１０２ａ、１０２ｂを係止位置まで案内するときに、案内されたケーブルエンド１０２ａ、１０２ｂを係止位置で係止状態を維持することが難しく、インナーケーブル１０１ａ、１０１ｂが安定しない。その結果、ジョイントピース１０３の摺動抵抗は低くされてはいるが、ジョイントピース１０３へインナーケーブル１０１ａ、１０１ｂのケーブルエンド１０２ａ、１０２ｂの組み付けは難しくなってしまう。 The joint piece 103 having such a penetrating structure is lightweight because it has openings on the top surface and the bottom surface, has a small contact area with the case 104, and has low sliding resistance. However, when the cable ends 102a and 102b are inserted from the top surface to the bottom surface, the cable ends 102a and 102b may penetrate through the opening on the bottom surface. Therefore, after guiding the cable ends 102a, 102b to the locking position of the joint piece 103 and then guiding the other cable ends 102a, 102b to the locking position, the guided cable ends 102a, 102b are held at the locking position. It is difficult to maintain the locked state, and the inner cables 101a and 101b are not stable. As a result, although the sliding resistance of the joint piece 103 is lowered, it is difficult to assemble the cable ends 102a and 102b of the inner cables 101a and 101b to the joint piece 103.
　そこで、本発明は上記問題に鑑みて、ジョイントピースとケースとの摺動抵抗を抑制し、ジョイントピースへのケーブルの組み付けを容易にすることができる連結機構の提供を目的とする。 Therefore, in view of the above problems, an object of the present invention is to provide a coupling mechanism that can suppress the sliding resistance between the joint piece and the case and facilitate the assembly of the cable to the joint piece.

　また、前記ケースが開閉可能な蓋を備え、前記蓋が、前記ケーブルエンドがジョイントピースに挿入された状態で、前記上開口を覆って前記ジョイントピースからの前記ケーブルエンドの離脱を抑制可能に構成されることが好ましい。 In addition, the case includes a lid that can be opened and closed, and the lid covers the upper opening in a state where the cable end is inserted into the joint piece, and can be configured to suppress detachment of the cable end from the joint piece. It is preferred that
　また、前記ケースが、前記底面を有する底面側部材と、前記蓋を有する蓋側部材とを備え、前記底面側部材の、前記摺動方向における両端に、前記ケーブルが挿通されるアウターケーシングを固定するアウターケーシング固定部を備え、前記アウターケーシング固定部に、前記アウターケーシングが前記底面側部材から離脱することを防止する離脱防止部が設けられていることが好ましい。 The case includes a bottom side member having the bottom surface and a lid side member having the lid, and an outer casing through which the cable is inserted is fixed to both ends of the bottom side member in the sliding direction. It is preferable that the outer casing fixing part is provided with a detachment preventing part that prevents the outer casing from detaching from the bottom surface side member.

　以下、図面を参照し、本発明の連結機構を詳細に説明する。本発明の連結機構は、操作部材による操作力を作動部材へ伝達するために、操作側部材又は作動側部材へ取り付けられる一方のケーブルと作動側部材又は操作側部材へ取り付けられる他方のケーブルとを連結するために用いられる。連結機構は、たとえば、ケーブルとしてのインナーケーブルと、インナーケーブルが挿通されるアウターケーシングを有するコントロールケーブルを用いてコントロールケーブルにより操作される車両のシートを操作するシート操作装置や、フューエルリッドの開閉操作をする開閉機構などに用いられるが、複数のケーブルを連結し、それら複数のケーブルを介して操作力を伝達するものであれば、特に用途は限定されるものではなく、車両以外の用途に用いてもよい。 Hereinafter, the connecting mechanism of the present invention will be described in detail with reference to the drawings. The connection mechanism of the present invention includes one cable attached to the operation side member or the operation side member and the other cable attached to the operation side member or the operation side member in order to transmit the operation force by the operation member to the operation member. Used to connect. The coupling mechanism, for example, is a seat operating device that operates a vehicle seat operated by a control cable using an inner cable as a cable and a control cable having an outer casing through which the inner cable is inserted, and a fuel lid opening / closing operation. As long as it can be used for opening and closing mechanisms, etc., it can be used for applications other than vehicles, as long as it connects multiple cables and transmits operating force through these cables. Also good.
　図１に示されるように、本発明の一実施形態における連結機構１は、インナーケーブル２１ａ、２１ｂと、インナーケーブル２１ａ、２１ｂが摺動可能に挿通されたアウターケーシング２３ａ、２３ｂと、インナーケーブル２１ａ、２１ｂのケーブルエンド２２ａ、２２ｂが係止される係止部３１（図２（ａ）および（ｃ）参照）を有するジョイントピース３と、ジョイントピース３を摺動可能に収容する収容空間Ｓを有するケース４とを備えている。 As shown in FIG. 1, the connecting mechanism 1 according to one embodiment of the present invention includes an inner cable 21a, 21b, an outer casing 23a, 23b in which the inner cable 21a, 21b is slidably inserted, and an inner cable 21a. A joint piece 3 having a locking portion 31 (see FIGS. 2A and 2C) to which the cable ends 22a and 22b of 21b are locked, and a receiving space S for slidably receiving the joint piece 3. The case 4 is provided.
　インナーケーブル２１ａ、２１ｂは、シートレバーなどの操作部（図示せず）からの操作力をシートのロック機構等の***作部（図示せず）までに連結機構１を介して伝達するための部材である。インナーケーブル２１ａ、２１ｂは、図１に示されるように、アウターケーシング２３ａ、２３ｂに摺動可能に挿通され、アウターケーシング２３ａ、２３ｂの端部は、ケース４に固定されている。アウターケーシング２３ａ、２３ｂは、操作されるインナーケーブル２１ａ、２１ｂのそれぞれの両端部間を保護している。 Inner cables 21a and 21b are members for transmitting an operating force from an operating portion (not shown) such as a seat lever to an operated portion (not shown) such as a seat locking mechanism via the coupling mechanism 1. It is. As shown in FIG. 1, the inner cables 21 a and 21 b are slidably inserted into the outer casings 23 a and 23 b, and the end portions of the outer casings 23 a and 23 b are fixed to the case 4. The outer casings 23a and 23b protect between both ends of the operated inner cables 21a and 21b.
　インナーケーブル２１ａ、２１ｂの一端部には、ケーブルエンド２２ａ、２２ｂが設けられ、ジョイントピース３に係止されている。なお、図示はしていないが、インナーケーブル２１ａ、２１ｂの他端にも、ケーブルエンドが設けられている。ケーブルエンド２２ａ、２２ｂは、インナーケーブル２１ａ、２１ｂをジョイントピース３に係止し、操作部の操作力を連結機構を介して作動部へ伝達することができる強度を有するものであれば特に限定されず、球状、円柱状、角柱等、任意の形状を用いることができる。 Cable ends 22 a and 22 b are provided at one end portions of the inner cables 21 a and 21 b and are locked to the joint piece 3. Although not shown, cable ends are also provided at the other ends of the inner cables 21a and 21b. The cable ends 22a and 22b are not particularly limited as long as the cable ends 22a and 22b have strength capable of locking the inner cables 21a and 21b to the joint piece 3 and transmitting the operation force of the operation unit to the operation unit via the coupling mechanism. Any shape such as a spherical shape, a cylindrical shape, or a prismatic shape can be used.
　インナーケーブル２１ａ、２１ｂの本数は、連結機構１が用いられる用途に応じて適宜変更が可能である。図１では、連結機構１から一方側に延びるインナーケーブル２１ａ（以下、単に一方のインナーケーブル２１ａという）と、他方側に延びるインナーケーブル２１ｂ（以下、単に他方のインナーケーブル２１ｂという）が、それぞれ２本ずつ示されている。しかしながら、インナーケーブル同士を、ジョイントピース３を介して連結するものであれば、１本ずつを連結してもよいし、１本と複数本、複数本と複数本を連結しても構わないが、ジョイントピースにインナーケーブルを係止させた状態の維持が容易であることから、少なくとも片側に複数本延びるように複数本のインナーケーブルを有することが好ましい。 The number of the inner cables 21a and 21b can be appropriately changed according to the application for which the coupling mechanism 1 is used. In FIG. 1, two inner cables 21a (hereinafter simply referred to as one inner cable 21a) extending from the coupling mechanism 1 to one side and two inner cables 21b (hereinafter simply referred to as the other inner cable 21b) extending to the other side are provided. Each book is shown. However, as long as the inner cables are connected to each other via the joint piece 3, the cables may be connected one by one, or one and a plurality, or a plurality and a plurality may be connected. Since it is easy to maintain the state in which the inner cable is locked to the joint piece, it is preferable to have a plurality of inner cables extending at least on one side.
　インナーケーブル２１ａ、２１ｂのケーブルエンド２２ａ、２２ｂは、ジョイントピース３の係止部３１に係止されてジョイントピース３に接続される。ジョイントピース３は、一方のインナーケーブル２１ａと他方のインナーケーブル２１ｂとを連結する部材である。また、ジョイントピース３は、一方のインナーケーブル２１ａと他方のインナーケーブル２１ｂとを連結することにより、一方のインナーケーブル２１ａへ伝達された操作部の操作力を他方のインナーケーブル２１ｂに伝達する。 The cable ends 22 a and 22 b of the inner cables 21 a and 21 b are locked to the locking portion 31 of the joint piece 3 and connected to the joint piece 3. The joint piece 3 is a member that connects one inner cable 21a and the other inner cable 21b. Moreover, the joint piece 3 transmits the operation force of the operation part transmitted to one inner cable 21a to the other inner cable 21b by connecting one inner cable 21a and the other inner cable 21b.
　ジョイントピース３は、操作部の操作力がインナーケーブル２１ａ、２１ｂを介して作動部へ伝達されるように、ケース内４に摺動可能に収容されている。たとえば、インナーケーブル２１ａが操作部により図１中、左側に向かって引き操作されると、インナーケーブル２１ａのケーブルエンド２２ａが係止されたジョイントピース３がインナーケーブル２１ａに引っ張られてケース４内を左側に向かって摺動して、ジョイントピース３にケーブルエンド２２ｂが係止されたインナーケーブル２１ｂも左側に引っ張られる。このように、操作力は、インナーケーブル２１ａ、２１ｂ及びジョイントピース３を介して作動部へ操作力が伝達される。 The joint piece 3 is slidably accommodated in the case 4 so that the operating force of the operating portion is transmitted to the operating portion via the inner cables 21a and 21b. For example, when the inner cable 21a is pulled toward the left side in FIG. 1 by the operating portion, the joint piece 3 to which the cable end 22a of the inner cable 21a is locked is pulled by the inner cable 21a to move inside the case 4. The inner cable 21b sliding to the left side and having the cable end 22b locked to the joint piece 3 is also pulled to the left side. As described above, the operating force is transmitted to the operating portion via the inner cables 21 a and 21 b and the joint piece 3.
　図１では、全体形状が略直方体状のジョイントピース３が示されているが、ジョイントピース３は、インナーケーブル２１ａ、２１ｂを連結することができ、ケース４内を摺動可能な外側形状を有し、軽量化等のために底部にケーブルエンド１０２ａ、１０２ｂが貫通可能な開口を有している。ジョイントピース３の形状は、これらの要素を満たすものであれば使用状況に応じて適宜変形可能であり、例えば、回転可能な方向転換部材にインナーケーブル２１ａ、２１ｂを連結し、操作部による操作力の方向を異なる方向へ変換して作動部へ出力するものであっても良く、特に限定されない。なお、ジョイントピース３の詳細については後述する。 In FIG. 1, a joint piece 3 having a substantially rectangular parallelepiped shape is shown, but the joint piece 3 can connect the inner cables 21 a and 21 b and has an outer shape that can slide inside the case 4. In order to reduce the weight, the cable ends 102a and 102b can be penetrated through the bottom. The shape of the joint piece 3 can be appropriately modified according to the use conditions as long as these elements are satisfied. For example, the inner cables 21a and 21b are connected to a rotatable direction changing member, and the operation force by the operation unit The direction may be changed to a different direction and output to the operating unit, and is not particularly limited. The details of the joint piece 3 will be described later.
　ケース４は、ジョイントピース３を摺動可能に収容する収容部材である。ケース４は、ジョイントピース３が摺動する底面４１と、底面４１から立設された壁部４４とにより形成される収容空間Ｓを有する底面側部材４ａを備えている。収容空間Ｓは、インナーケーブル２１ａ又はインナーケーブル２１ｂが操作されたときに、インナーケーブル２１ｂ又はインナーケーブル２１ａへ操作力を伝達する方向へジョイントピース３が摺動することができるようにされている。本実施形態では、図１に示されるように、ジョイントピース３が直線的に案内されて摺動できるように、ジョイントピース３の幅と同程度の幅を有した、ジョイントピース３の摺動方向に細長い収容空間Ｓが形成されている。また、ケース４の長手方向両端部には、図１に示されるように、インナーケーブル２１ａ、２１ｂが挿通されたアウターケーシング２３ａ、２３ｂのケーブルエンド２２ａ、２２ｂ側の端部が取り付けられている。ケース４の詳細については後述する。 Case 4 is a housing member that slidably houses the joint piece 3. The case 4 includes a bottom surface side member 4 a having an accommodation space S formed by a bottom surface 41 on which the joint piece 3 slides and a wall portion 44 standing from the bottom surface 41. The accommodation space S is configured such that when the inner cable 21a or the inner cable 21b is operated, the joint piece 3 can slide in a direction in which an operating force is transmitted to the inner cable 21b or the inner cable 21a. In the present embodiment, as shown in FIG. 1, the sliding direction of the joint piece 3 having the same width as that of the joint piece 3 so that the joint piece 3 can be linearly guided and slid. A long and narrow accommodation space S is formed. Further, as shown in FIG. 1, end portions on the cable ends 22 a and 22 b side of the outer casings 23 a and 23 b through which the inner cables 21 a and 21 b are inserted are attached to both ends in the longitudinal direction of the case 4. Details of case 4 will be described later.
　つぎに、本発明の連結機構１のジョイントピース３およびケース４の詳細について説明する。 Next, details of the joint piece 3 and the case 4 of the coupling mechanism 1 of the present invention will be described.
　本発明の連結機構１に用いられるジョイントピース３には、図２（ａ）～（ｃ）に示されるように、接続領域Ｃにおいて、ジョイントピース３の上側において開口する上開口３２と、上開口３２に貫通してジョイントピース３の摺動面３３（図２（ｂ）参照）に開口し、ジョイントピース３の摺動方向に沿って形成された下開口３４と、ケーブルエンド２２ａ、２２ｂが係止する係止部３１とが設けられている。接続領域Ｃとは、ジョイントピース３内においてケーブルエンド２２ａ、２２ｂがジョイントピース３に挿入され、係止部３１へケーブルエンド２２ａ、２２ｂが位置するように変位させることができる範囲である。接続領域Ｃの周縁部の一部において係止部３１が形成され、接続領域Ｃは、少なくとも係止部３１へケーブルエンド２２ａ、２２ｂが係止可能な領域を有していれば良い。 As shown in FIGS. 2 (a) to 2 (c), the joint piece 3 used in the coupling mechanism 1 of the present invention includes an upper opening 32 that opens above the joint piece 3 in the connection region C, and an upper opening. 32 is opened to the sliding surface 33 of the joint piece 3 (see FIG. 2B), and the lower opening 34 formed along the sliding direction of the joint piece 3 is connected to the cable ends 22a and 22b. A locking portion 31 to be stopped is provided. The connection region C is a range in which the cable ends 22 a and 22 b are inserted into the joint piece 3 in the joint piece 3 and can be displaced to the locking portion 31 so that the cable ends 22 a and 22 b are positioned. The engaging part 31 is formed in a part of the peripheral edge of the connection area C, and the connection area C only needs to have an area where the cable ends 22a and 22b can be engaged with at least the engaging part 31.
　上開口３２は、ジョイントピース３の上面３５に形成され、インナーケーブル２１ａ、２１ｂのケーブルエンド２２ａ、２２ｂをジョイントピース３に接続する際に、ケーブルエンド２２ａ、２２ｂが挿入される開口である。なお、本明細書において、「上側」、「上面」、「上開口」における「上」とは、インナーケーブル２１ａ、２１ｂの操作によりケース４の底面４１と摺動するジョイントピース３の摺動面３３を基準として、摺動面３３を下とした場合の相対的な位置をいうものであり、連結機構１が車体等の取り付け対象物に取り付けられたときの、上下をいうものではない。「下開口」における「下」についても、同様である。 The upper opening 32 is formed in the upper surface 35 of the joint piece 3 and is an opening into which the cable ends 22a and 22b are inserted when the cable ends 22a and 22b of the inner cables 21a and 21b are connected to the joint piece 3. In the present specification, “upper” in the “upper side”, “upper surface”, and “upper opening” means the sliding surface of the joint piece 3 that slides on the bottom surface 41 of the case 4 by the operation of the inner cables 21a and 21b. This is a relative position when the sliding surface 33 is on the lower side with reference to 33, and does not mean up and down when the coupling mechanism 1 is attached to an attachment object such as a vehicle body. The same applies to “lower” in “lower opening”.
　上開口３２は、ケーブルエンド２２ａ、２２ｂを係止部３１へ案内できるように、ケーブルエンド２２ａ、２２ｂをジョイントピース３内の接続領域Ｃにおける空間へ挿入することができれば、その形状、大きさは特に限定されるものではない。係止部３１に係止されたケーブルエンド２２ａ、２２ｂからインナーケーブル２１ａ、２１ｂが導出部４５へ導出される部位に対して、上開口３２は、係止部３１側に形成されることが好ましい。これにより、上開口３２から挿入したケーブルエンド２２ａ、２２ｂをスムーズに係止部３１へ係止させることができる。上開口３２は、後述する図２（ａ）に示す形状以外に、ジョイントピース３の摺動方向に直線的に延びるスリット状の開口等であっても構わない。 If the cable ends 22 a and 22 b can be inserted into the space in the connection region C in the joint piece 3 so that the cable ends 22 a and 22 b can be guided to the locking portion 31, the shape and size of the upper opening 32 are It is not particularly limited. The upper opening 32 is preferably formed on the locking portion 31 side with respect to a portion where the inner cables 21a, 21b are led out to the lead-out portion 45 from the cable ends 22a, 22b locked to the locking portion 31. . Thereby, the cable ends 22 a and 22 b inserted from the upper opening 32 can be smoothly locked to the locking portion 31. The upper opening 32 may be a slit-like opening or the like that extends linearly in the sliding direction of the joint piece 3 other than the shape shown in FIG.
　図２（ｂ）においては、下開口３４を見やすくするために、上開口３２を２点鎖線で示している。下開口３４は、図２（ｂ）および（ｃ）に示されるように、ジョイントピース３の摺動面３３において開口しており、上開口３２と貫通している。下開口３４は、図２（ｂ）に示されるように、摺動面３３に、ジョイントピース３の摺動方向に沿って、形成されており、摺動方向と同じ方向に長さを有するようにされている。摺動面３３については、ケース４内でジョイントピース３自体が摺動することができるように形成されていればよく、ジョイントピース３の下側の面において、ケーブルエンド２２ａ、２２ｂが貫通できる下開口３４を有している。これにより、ジョイントピース３がケース４内を摺動するときの摺動抵抗が軽減されるとともに、ジョイントピース３が軽量化される。下開口３４は、摺動面３３の摺動抵抗を減らすことができる形状であれば、その形状は特に限定されないが、摺動面３３の摺動方向に垂直な方向である摺動面３３の幅方向（図２（ｂ）中、上下方向）が摺動方向よりも短く形成されることが好ましい。したがって、図２（ｂ）に示すように、摺動方向に沿って形成された２つの長孔状の下開口３４により、ケース４との接触面積を、摺動方向および幅方向で減らしてもよいし、摺動方向に沿って形成されたより幅広の１つの下開口としてもよいし、より幅広の下開口を摺動方向に２つ設けたものであってもよい。 In FIG. 2B, in order to make the lower opening 34 easier to see, the upper opening 32 is indicated by a two-dot chain line. As shown in FIGS. 2B and 2C, the lower opening 34 opens at the sliding surface 33 of the joint piece 3 and penetrates the upper opening 32. As shown in FIG. 2B, the lower opening 34 is formed on the sliding surface 33 along the sliding direction of the joint piece 3, and has a length in the same direction as the sliding direction. Has been. The sliding surface 33 only needs to be formed so that the joint piece 3 itself can slide in the case 4. The lower surface of the joint piece 3 can be penetrated by the cable ends 22 a and 22 b. An opening 34 is provided. Thereby, the sliding resistance when the joint piece 3 slides in the case 4 is reduced, and the joint piece 3 is reduced in weight. The shape of the lower opening 34 is not particularly limited as long as the sliding resistance of the sliding surface 33 can be reduced, but the shape of the sliding surface 33 that is perpendicular to the sliding direction of the sliding surface 33 is not limited. The width direction (the vertical direction in FIG. 2B) is preferably shorter than the sliding direction. Therefore, as shown in FIG. 2B, even if the contact area with the case 4 is reduced in the sliding direction and the width direction by the two long hole-shaped lower openings 34 formed along the sliding direction. Alternatively, one wider lower opening formed along the sliding direction may be used, or two wider lower openings may be provided in the sliding direction.
　係止部３１は、ケーブルエンド２２ａ、２２ｂが上開口３２から挿入された後に係止される部位である。係止部３１は、インナーケーブル２１ａ、２１ｂが引き操作されたときに、ケーブルエンド２２ａ、２２ｂが係止部３１に当接して係止され、ジョイントピース３をケース４内で摺動させることができるものであれば、特にその形状は限定されるものではないが、ケーブルエンドの形状に対応したケーブルエンドとの接触面を有していることが好ましい。 The locking portion 31 is a portion that is locked after the cable ends 22 a and 22 b are inserted from the upper opening 32. When the inner cables 21a and 21b are pulled, the locking portion 31 is locked by the cable ends 22a and 22b coming into contact with the locking portion 31 and sliding the joint piece 3 in the case 4. If possible, the shape is not particularly limited, but preferably has a contact surface with the cable end corresponding to the shape of the cable end.
　ケース４が有する底面４１は、図３（ａ）に示されるように、インナーケーブル２１ａ、２１ｂのジョイントピース３への組み付け時等にジョイントピース３が載置される。ケース４は、ジョイントピース３に取り付けられたインナーケーブル２１ａ、２１ｂを操作部および作動部へ導出するための導出部４５を有している。底面４１は、ジョイントピース３の摺動面３３と接触する面であり、インナーケーブル２１ａ、２１ｂの操作時に、ジョイントピース３の摺動面３３と、ケース４の底面４１とが、インナーケーブル２１ａ、２１ｂの操作力を伝達する方向である移動方向に摺動可能に構成されている。底面４１は、ジョイントピース３との摺動の際に摺動面３３の一部と少なくとも接触する摺動領域を有しており、本実施形態においては、ケース４の長手方向に摺動可能に構成されている。また、底面４１は、ケーブルエンド２２ａ、２２ｂの組み付け時にケーブルエンド２２ａ、２２ｂと接触する規制領域とを有しており、ジョイントピース３の上開口３２から前記ケーブルエンド２２ａ、２２ｂを挿入したときに、ケーブルエンド２２ａ、２２ｂが下開口３４から貫通して移動することを規制可能に構成されている。たとえば、底面４１は、本実施形態においては平面として構成されているが、より摺動面３３との接触面積を減らすために、摺動方向に沿って底面４１に設けられたレール状の突出部を設けるなど、立体的な摺動面３３への接触部を前記摺動領域に設けてもよい。また、底面４１を平面とし、立体的な接触部を摺動面３３に設けてもよい。なお、蓋４２を閉じた状態における底面側部材４ａと蓋側部材４ｂにより形成される、軸方向に垂直な断面での内周の形状と、ジョイントピース３の軸方向に垂直な断面での外周形状とが対応した形状となっている場合、ガタつきのない摺動が可能であるため好ましい。 As shown in FIG. 3A, the joint piece 3 is placed on the bottom surface 41 of the case 4 when the inner cables 21 a and 21 b are assembled to the joint piece 3. The case 4 has a lead-out portion 45 for leading the inner cables 21a and 21b attached to the joint piece 3 to the operation portion and the operation portion. The bottom surface 41 is a surface that is in contact with the sliding surface 33 of the joint piece 3, and when the inner cables 21a and 21b are operated, the sliding surface 33 of the joint piece 3 and the bottom surface 41 of the case 4 are connected to the inner cable 21a, It is configured to be slidable in the moving direction, which is the direction in which the operating force of 21b is transmitted. The bottom surface 41 has a sliding region that contacts at least a part of the sliding surface 33 when sliding with the joint piece 3. In the present embodiment, the bottom surface 41 can slide in the longitudinal direction of the case 4. It is configured. Further, the bottom surface 41 has a restriction region that comes into contact with the cable ends 22a and 22b when the cable ends 22a and 22b are assembled, and when the cable ends 22a and 22b are inserted from the upper opening 32 of the joint piece 3. The cable ends 22a and 22b are configured to be able to regulate movement through the lower opening 34. For example, although the bottom surface 41 is configured as a flat surface in the present embodiment, a rail-shaped protrusion provided on the bottom surface 41 along the sliding direction in order to further reduce the contact area with the sliding surface 33. For example, a contact portion to the three-dimensional sliding surface 33 may be provided in the sliding region. Further, the bottom surface 41 may be a flat surface, and a three-dimensional contact portion may be provided on the sliding surface 33. In addition, the shape of the inner periphery in the cross section perpendicular to the axial direction and the outer periphery in the cross section perpendicular to the axial direction of the joint piece 3 formed by the bottom surface side member 4a and the lid side member 4b in the state where the lid 42 is closed. A shape corresponding to the shape is preferable because sliding without backlash is possible.
　つぎに、本発明の連結機構１におけるインナーケーブル２１ａ、２１ｂのジョイントピース３への組み付けについて図４（ａ）～（ｃ）を用いて説明する。なお、以下に説明する組み付け方法はあくまで一例であり、組み付け方法は以下の方法に限定されるものではない。 Next, assembly of the inner cables 21a and 21b to the joint piece 3 in the coupling mechanism 1 of the present invention will be described with reference to FIGS. 4 (a) to 4 (c). The assembly method described below is merely an example, and the assembly method is not limited to the following method.
　図４（ａ）に示されるように、インナーケーブル２１ａ、２１ｂがジョイントピース３に組み付けられる前は、ケース４の底面４１にジョイントピース３の摺動面３３が接触する形で、ケース４にジョイントピース３が載置されている。このケース４の底面４１上に載置されたジョイントピース３の上面３５側から、インナーケーブル２１ａ、２１ｂのケーブルエンド２２ａ、２２ｂを、ジョイントピース３の上開口３２から底面４１に向かって挿入する（図４（ｂ）および図４（ｃ）参照）。ジョイントピース３は、上開口３２におけるケーブルエンド２２ａ、２２ｂが挿入される部位の下方には、下開口３４が形成されているため、上開口３２と下開口３４は垂直方向に連通されている。上開口３２から挿入されたケーブルエンド２２ａ、２２ｂは、ケーブルエンド２２ａ、２２ｂの一部が下開口３４を貫通してケース４の底面４１と接触するため、下開口３４から突き抜けることが規制される。したがって、底面４１は、ジョイントピース３２の上開口３２からケーブルエンド２２ａ、２２ｂを挿入したときに、ケーブルエンド２２ａ、２２ｂが下開口３４から貫通して移動することを規制する。 As shown in FIG. 4A, before the inner cables 21a and 21b are assembled to the joint piece 3, the sliding surface 33 of the joint piece 3 contacts the bottom surface 41 of the case 4 so that the joint is connected to the case 4. Piece 3 is placed. The cable ends 22a and 22b of the inner cables 21a and 21b are inserted from the upper opening 32 of the joint piece 3 toward the bottom surface 41 from the upper surface 35 side of the joint piece 3 placed on the bottom surface 41 of the case 4 ( (Refer FIG.4 (b) and FIG.4 (c)). Since the joint piece 3 has a lower opening 34 formed below the portion of the upper opening 32 where the cable ends 22a and 22b are inserted, the upper opening 32 and the lower opening 34 communicate with each other in the vertical direction. The cable ends 22a and 22b inserted from the upper opening 32 are restricted from penetrating from the lower opening 34 because part of the cable ends 22a and 22b penetrates the lower opening 34 and contacts the bottom surface 41 of the case 4. . Accordingly, the bottom surface 41 restricts the cable ends 22a and 22b from penetrating from the lower opening 34 when the cable ends 22a and 22b are inserted from the upper opening 32 of the joint piece 32.
　ケーブルエンド２２ａは図４（ｂ）に示す状態で、ケース４の底面４１と接触し、ケーブルエンド２２ａと底面４１との接触箇所を支点として、インナーケーブル２１ａを図４（ｂ）中に矢印で示す方向に回転させた後、図４（ｃ）に示すように、ジョイントピース３の係止部３１までケーブルエンド２２ａを移動させる。そして、インナーケーブル２１ａが導出部４５へ向けてジョイントピース３の係合部３１から導出され、インナーケーブル２１ａのジョイントピース３への接続が完了する。同様に、他方のインナーケーブル２１ｂのケーブルエンド２２ｂもジョイントピース３の係止部３１まで移動させ、インナーケーブル２１ｂのジョイントピース３への接続をすればよい。 In the state shown in FIG. 4B, the cable end 22a contacts the bottom surface 41 of the case 4, and the inner cable 21a is indicated by an arrow in FIG. 4B with the contact point between the cable end 22a and the bottom surface 41 as a fulcrum. After rotating in the direction shown, the cable end 22a is moved to the locking portion 31 of the joint piece 3 as shown in FIG. And the inner cable 21a is derived | led-out from the engaging part 31 of the joint piece 3 toward the derivation | leading-out part 45, and the connection to the joint piece 3 of the inner cable 21a is completed. Similarly, the cable end 22b of the other inner cable 21b may be moved to the locking portion 31 of the joint piece 3 to connect the inner cable 21b to the joint piece 3.
　本発明は、図４（ａ）～（ｃ）に示したように、摺動抵抗の低減のためにケーブルエンド２２ａ、２２ｂが突き抜ける幅の下開口３４を有する構造であっても、ジョイントピース３の上開口３２からケーブルエンド２２ａ、２２ｂを挿入したときに、ケース４の底面４１がケーブルエンド２２ａ、２２ｂの下開口３４から貫通する移動を規制して、インナーケーブル２１ａ、２１ｂの組み付け時にケーブルエンド２２ａ、２２ｂの位置が安定して、従来よりも遥かに組み付けやすく構成されている。さらに、上開口３２と下開口３４とが貫通して設けられているので、ジョイントピース３が軽量化され、ジョイントピース３を軽量化することにより、ジョイントピース３の摺動時の摩擦抵抗が小さくなり、インナーケーブル２１ａ、２１ｂの操作がスムーズとなる。 In the present invention, as shown in FIGS. 4A to 4C, the joint piece 3 has a structure having a lower opening 34 with a width through which the cable ends 22a and 22b penetrate to reduce sliding resistance. When the cable ends 22a and 22b are inserted from the upper openings 32, the bottom end 41 of the case 4 is restricted from moving through the lower openings 34 of the cable ends 22a and 22b, and the cable ends are assembled when the inner cables 21a and 21b are assembled. The positions of 22a and 22b are stable and much easier to assemble than before. Further, since the upper opening 32 and the lower opening 34 are provided so as to penetrate, the joint piece 3 is reduced in weight, and by reducing the weight of the joint piece 3, the frictional resistance during sliding of the joint piece 3 is reduced. Thus, the operation of the inner cables 21a and 21b becomes smooth.
　また、本実施形態では、図１および図３（ａ）～（ｃ）に示されるように、ケース４が開閉可能な蓋４２を備え、蓋４２が、ケーブルエンド２２ａ、２２ｂがジョイントピース３に挿入された状態で、上開口３２を覆ってジョイントピース３からのケーブルエンド２２ａ、２２ｂの離脱を抑制可能に構成されている。したがって、蓋４２を設けることにより、インナーケーブル２１ａ、２１ｂの組み付け時には組み付けやすく、組み付け後は、ケーブルエンド２２ａ、２２ｂの離脱が抑制される連結機構１を提供することができる。 Further, in this embodiment, as shown in FIGS. 1 and 3A to 3C, the case 4 includes a lid 42 that can be opened and closed, and the lid 42 includes the cable ends 22a and 22b as the joint piece 3. In the inserted state, the upper opening 32 is covered so that the detachment of the cable ends 22a and 22b from the joint piece 3 can be suppressed. Therefore, by providing the lid 42, it is possible to provide the coupling mechanism 1 that is easy to assemble when the inner cables 21a and 21b are assembled, and that the detachment of the cable ends 22a and 22b is suppressed after the assembly.
　本実施形態のように、ケース４に開閉可能な蓋４２を設けた場合には、インナーケーブル２１ａ、２１ｂの両端にケーブルエンド２２ａ、２２ｂを鋳込んだ後であっても、ジョイントピース３への組み付けが可能であり、ケース４の収容空間Ｓにジョイントピース３を収容した状態でインナーケーブル２１ａ、２１ｂの組み付けが可能となる。なお、開閉可能な蓋４２は、上開口３２を覆い、ジョイントピース３からのケーブルエンド２２ａ、２２ｂの上開口３２からの離脱を抑制することができるものであればよく、図示した構成に限定されるものではない。 When the case 42 is provided with an openable / closable lid 42 as in the present embodiment, even after the cable ends 22a and 22b are cast on both ends of the inner cables 21a and 21b, Assembling is possible, and the inner cables 21 a and 21 b can be assembled in a state where the joint piece 3 is accommodated in the accommodating space S of the case 4. The lid 42 that can be opened and closed is only required to cover the upper opening 32 and to prevent the cable ends 22a and 22b from being detached from the upper opening 32 from the joint piece 3, and is limited to the illustrated configuration. It is not something.
　なお、本実施形態では、ケース４は、底面４１を有する底面側部材４ａと、蓋４２を有する蓋側部材４ｂとを備え、蓋側部材４ｂが底面側部材４ａに対して開閉可能に構成されている。底面側部材４ａは、摺動面３３と摺動する底面４１と、収容空間Ｓを構成する壁部４４と、ジョイントピース３を収容空間Ｓ内へ挿入する挿入開口部４６とを有する部材であり、インナーケーブル２１ａ、２１ｂの組み付け時にジョイントピース３を収容する部材である。蓋側部材４ｂは、ジョイントピース３を収容した底面側部材４ａの挿入開口部４６を覆う蓋４２と、底面側部材４ａと係合する係合部Ｅ１を有し、底面側部材４ａと係合することで挿入開口部４６を蓋をした状態が維持される。蓋側部材４ｂは、図３（ａ）および（ｃ）に示されるように、底面側部材４ａに対してヒンジＨにより接続されて、底面側部材４ａに対してヒンジＨを中心とした開閉が可能となるように構成されている。蓋側部材４ｂには、図３（ａ）に示されるように、係合爪として示された係合部Ｅ１が形成され、底面側部材４ａに形成された被係合部Ｅ２に係合部Ｅ１が係合して、底面側部材４ａを蓋側部材４ｂにより覆って閉鎖され、閉鎖状態が維持される。なお、蓋側部材４ｂと底面側部材４ａとを係合させる場合、係合部Ｅ１および被係合部Ｅ２は、図示した構造に限定されるものではなく、他の係合構造であっても構わない。 In the present embodiment, the case 4 includes a bottom surface side member 4a having a bottom surface 41 and a lid side member 4b having a lid 42, and the lid side member 4b is configured to be openable and closable with respect to the bottom surface side member 4a. ing. The bottom surface side member 4a is a member having a bottom surface 41 that slides with the sliding surface 33, a wall portion 44 that constitutes the accommodation space S, and an insertion opening 46 that inserts the joint piece 3 into the accommodation space S. This is a member that accommodates the joint piece 3 when the inner cables 21a and 21b are assembled. The lid side member 4b has a lid 42 that covers the insertion opening 46 of the bottom surface side member 4a that houses the joint piece 3, and an engagement portion E1 that engages with the bottom surface side member 4a, and engages with the bottom surface side member 4a. By doing so, the state where the insertion opening 46 is covered is maintained. As shown in FIGS. 3A and 3C, the lid-side member 4b is connected to the bottom-side member 4a by a hinge H, and can be opened and closed around the hinge H with respect to the bottom-side member 4a. It is configured to be possible. As shown in FIG. 3A, the lid-side member 4b is formed with an engaging portion E1 shown as an engaging claw, and is engaged with the engaged portion E2 formed on the bottom-side member 4a. E1 is engaged, the bottom surface side member 4a is covered with the lid side member 4b and closed, and the closed state is maintained. In addition, when engaging the cover side member 4b and the bottom face side member 4a, the engaging part E1 and the to-be-engaged part E2 are not limited to the structure shown in figure, Even if it is another engaging structure. I do not care.
　また、本実施形態では、図３（ａ）および（ｃ）に示されるように、アウターケーシング２３ａ、２３ｂを用いる場合は、底面側部材４ａの、摺動方向における両端に、インナーケーブル２１ａ、２１ｂが挿通されるアウターケーシング２３ａ、２３ｂを固定するアウターケーシング固定部４３を備え、アウターケーシング固定部４３に、アウターケーシング２３ａ、２３ｂが底面側部材４ａから離脱することを防止する離脱防止リブ４３ａが設けられていてもよい。 In the present embodiment, as shown in FIGS. 3A and 3C, when the outer casings 23a and 23b are used, the inner cables 21a and 21b are provided at both ends in the sliding direction of the bottom surface side member 4a.

　アウターケーシング固定部４３は、ジョイントピース３に取り付けられるケーブルエンド２２ａ、２２ｂ側のアウターケーシング２３ａ、２３ｂの端部をケース４に固定する部位である。アウターケーシング固定部４３は、図３（ａ）および（ｃ）に示されるように、アウターケーシング２３ａ、２３ｂの端部が収容される凹部とアウターケーシング２３ａ、２３ｂの外周に係合する離脱防止部とを有している。本実施形態では凹部は、断面が半円状の凹部が形成され、離脱防止部は、凹部の縁からアウターケーシング２３ａ、２３ｂの外周に係合する離脱防止リブ４３ａとして突出して形成されている。離脱防止リブ４３ａは、アウターケーシング２３ａ、２３ｂが収容される凹部の縁から、アウターケーシング２３ａ、２３ｂの軸心方向に向かってわずかに張り出し、アウターケーシング２３ａ、２３ｂの外周側面と係合して、アウターケーシング２３ａ、２３ｂの離脱を防止する。つまり、凹部と離脱防止部とによって、アウターケーシング２３ａ、２３ｂの端部外周が径方向内側へ支持されているため、アウターケーシング２３ａ、２３ｂの径方向外側への移動が規制されることにより離脱を防止することができる。この離脱防止リブ４３ａが設けられていることにより、一度係止されたインナーケーブル２１ａ、２１ｂが係止状態で安定し、インナーケーブル２１ａ、２１ｂのケーブルエンド２２ａ、２２ｂがジョイントピース３の係止部３１から外れにくくなる。したがって、よりジョイントピース３へのインナーケーブル２１ａ、２１ｂの組み付けが容易となる。すなわち、ケーブルエンド２２ａ、２２ｂの係止部３１への取り付けが完了した場合であっても、アウターケーシング２３ａ、２３ｂが固定されていないと、アウターケーシング２３ａ、２３ｂに挿通されたインナーケーブル２１ａ、２１ｂも安定しない。インナーケーブル２１ａ、２１ｂが安定していない場合、ケーブルエンド２２ａ、２２ｂが取り付けられても、インナーケーブル２１ａ、２１ｂが不安定な状態で動いてしまい、取り付けられたケーブルエンド２２ａ、２２ｂが係止部３１から外れてしまう可能性がある。しかしながら、離脱防止リブ４３ａが設けられていることにより、ジョイントピース３への接続が完了した一方のインナーケーブルを安定させ、他方のインナーケーブルの組み付けが容易となる。たとえば、図４（ｃ）に示されるように、アウターケーシング２３ａの離脱が防止されていることにより、ジョイントピース３への組み付けが完了した一方のインナーケーブル２１ａが組み付けられた状態で安定し、ケーブルエンド２２ａが外れにくい。そして、一方のインナーケーブル２１ａのケーブルエンド２２ａが外れにくいため、他方のインナーケーブル２１ｂを組み付ける際に、一方のインナーケーブル２１ａのケーブルエンド２２ａを押さえながら作業したりする必要がなく、一方のインナーケーブル２１ａの外れを気にせずに作業することができる。したがって、他方のインナーケーブル２１ｂの組み付けが容易となる。なお、離脱防止リブ４３ａは、アウターケーシング２３ａ、２３ｂの離脱を防止することができればよく、その形状は、図３（ａ）および（ｃ）に示す形状に限定されるものではない。 The outer casing fixing portion 43 is a portion for fixing the end portions of the outer casings 23 a and 23 b on the cable ends 22 a and 22 b side attached to the joint piece 3 to the case 4. As shown in FIGS. 3 (a) and 3 (c), the outer casing fixing portion 43 includes a recess for accommodating the ends of the outer casings 23a and 23b and a detachment preventing portion that engages with the outer peripheries of the outer casings 23a and 23b. And have. In the present embodiment, the concave portion is formed with a semicircular concave section, and the separation preventing portion is formed to project from the edge of the concave portion as a separation preventing rib 43a that engages with the outer periphery of the outer casing 23a, 23b. The separation preventing rib 43a slightly protrudes from the edge of the recess in which the outer casing 23a, 23b is accommodated toward the axial direction of the outer casing 23a, 23b, and engages with the outer peripheral side surface of the outer casing 23a, 23b. The detachment of the outer casings 23a and 23b is prevented. In other words, since the outer periphery of the end of the outer casing 23a, 23b is supported radially inward by the recess and the separation preventing part, the movement of the outer casing 23a, 23b to the radially outer side is restricted, so that the separation is prevented. Can be prevented. By providing the separation preventing rib 43a, the inner cables 21a, 21b once locked are stabilized in the locked state, and the cable ends 22a, 22b of the inner cables 21a, 21b are the locking portions of the joint piece 3. 31 becomes difficult to come off. Therefore, the assembly of the inner cables 21a and 21b to the joint piece 3 becomes easier. That is, even when the attachment of the cable ends 22a and 22b to the locking portion 31 is completed, if the outer casings 23a and 23b are not fixed, the inner cables 21a and 21b inserted through the outer casings 23a and 23b. Is not stable. When the inner cables 21a and 21b are not stable, even if the cable ends 22a and 22b are attached, the inner cables 21a and 21b move in an unstable state, and the attached cable ends 22a and 22b are locked portions. There is a possibility of deviating from 31. However, the provision of the separation preventing rib 43a stabilizes one inner cable that has been connected to the joint piece 3, and facilitates the assembly of the other inner cable. For example, as shown in FIG. 4 (c), since the outer casing 23a is prevented from being detached, the inner cable 21a, which has been assembled to the joint piece 3, is stably assembled, and the cable The end 22a is difficult to come off. And since the cable end 22a of one inner cable 21a is hard to come off, it is not necessary to work while pressing the cable end 22a of one inner cable 21a when assembling the other inner cable 21b. It is possible to work without worrying about detachment of 21a. Therefore, the other inner cable 21b can be easily assembled. The detachment prevention rib 43a only needs to prevent the detachment of the outer casings 23a and 23b, and the shape thereof is not limited to the shape shown in FIGS. 3 (a) and 3 (c).
　また、ジョイントピース３は、上述したように、インナーケーブル２１ａ、２１ｂのケーブルエンド２２ａ、２２ｂが挿入される上開口３２を有しているが、本実施形態では、図１および図２（ａ）に示されるように、上開口３２は、ジョイントピース３の摺動面３３と反対側の面である上面３５において、摺動方向に延びて開口した係止溝として形成されている。係止溝としての上開口３２は、ジョイントピース３の上面３５に、インナーケーブル２１ａ、２１ｂの摺動方向（図２（ａ）中、左右方向）に沿って延びている。係止溝としての上開口３２は、ジョイントピース３の中央側（ジョイントピース３の摺動方向における中央部）に設けられ、ケーブルエンド２２ａ、２２ｂが挿入される挿入部位３２ａと、挿入部位３２ａからジョイントピース３の端部に向かって、ケーブルエンド２２ａ、２２ｂの大きさよりも小さい、幅の狭い幅狭部位３２ｂと、挿入部位３２ａから挿入され、ケーブルエンド２２ａ、２２ｂ近傍のインナーケーブル２１ａ、２１ｂが幅狭部位３２ｂを通ってケーブルエンド２２ａ、２２ｂが係止され、ジョイントピース３の端部に位置する係止部位３２ｃとを有している。なお、ジョイントピース３の中央側とは、ジョイントピース３の摺動方向における中央近傍の位置をいい、ジョイントピース３の端部とは、ジョイントピース３の両端近傍の位置をいう。挿入部位３２ａは、ケーブルエンド２２ａ、２２ｂが挿入される部位であり、ケーブルエンド２２ａ、２２ｂが挿入可能な大きさ、形状に形成される。幅狭部位３２ｂは、ケーブルエンド２２ａ、２２ｂが挿入部位３２ａから挿入され、係止部３１まで移動する際に、インナーケーブル２１ａ、２１ｂは通ることができるが、ケーブルエンド２２ａ、２２ｂは挿入された状態から幅狭部位３２ｂから上方へ抜け出てジョイントピース３から外れないようにされている。係止部位３２ｃは、ケーブルエンド２２ａ、２２ｂが係止部３１に係止され、インナーケーブル２１ａ、２１ｂが導出部４５へ配置されるようにケース４の底面４１と略平行な状態まで倒されるときに（図４（ｃ）の左側のインナーケーブル２１ａの状態）、インナーケーブル２１ａ、２１ｂのケーブルエンド２２ａ、２２ｂ近傍が導出部４５へ向かって延出する際に通過する部位である。そして、係止部位３２ｃを通過したインナーケーブル２１ａ、２１ｂは、係止部３１からケース４の導出部４５へ向かって延出されるようにジョイントピース３の延出部３６へ配置される。延出部３６は、ジョイントピース３の係止部３１とケース４の導出部４５とを繋ぐ線上に設けられており、係止部３１に係止されたケーブルエンド２２ａ、２２ｂ近傍のインナーケーブル２１ａ、２１ｂが損傷しないようにジョイントピース３からインナーケーブル２１ａ、２１ｂを延出させる部位である。 Further, as described above, the joint piece 3 has the upper opening 32 into which the cable ends 22a and 22b of the inner cables 21a and 21b are inserted. In the present embodiment, the joint piece 3 is shown in FIGS. As shown in FIG. 3, the upper opening 32 is formed as a locking groove that extends in the sliding direction and opens on the upper surface 35 that is the surface opposite to the sliding surface 33 of the joint piece 3. The upper opening 32 as a locking groove extends on the upper surface 35 of the joint piece 3 along the sliding direction of the inner cables 21a, 21b (the left-right direction in FIG. 2A). The upper opening 32 as a locking groove is provided at the center side of the joint piece 3 (the center portion in the sliding direction of the joint piece 3), and the insertion portion 32a into which the cable ends 22a and 22b are inserted, and the insertion portion 32a Toward the end of the joint piece 3, the narrow portion 32b, which is narrower than the size of the cable ends 22a, 22b, and the inner portion 21a, 21b near the cable ends 22a, 22b are inserted from the insertion portion 32a. The cable ends 22 a and 22 b are locked through the narrow portion 32 b and have a locking portion 32 c located at the end of the joint piece 3. In addition, the center side of the joint piece 3 refers to the position near the center in the sliding direction of the joint piece 3, and the end of the joint piece 3 refers to the position near both ends of the joint piece 3. The insertion part 32a is a part into which the cable ends 22a and 22b are inserted, and is formed in a size and shape into which the cable ends 22a and 22b can be inserted. In the narrow portion 32b, the cable ends 22a and 22b are inserted from the insertion portion 32a, and the inner cables 21a and 21b can pass through when the cable ends 22a and 22b move to the locking portion 31, but the cable ends 22a and 22b are inserted. From the state, it is prevented from coming out from the narrow part 32b upward and coming off from the joint piece 3. When the locking portion 32c is tilted to a state substantially parallel to the bottom surface 41 of the case 4 so that the cable ends 22a, 22b are locked to the locking portion 31 and the inner cables 21a, 21b are arranged to the lead-out portion 45. (The state of the inner cable 21a on the left side in FIG. 4C) is a portion through which the vicinity of the cable ends 22a, 22b of the inner cables 21a, 21b passes when extending toward the lead-out portion 45. The inner cables 21 a and 21 b that have passed through the locking portion 32 c are arranged on the extending portion 36 of the joint piece 3 so as to extend from the locking portion 31 toward the lead-out portion 45 of the case 4. The extending portion 36 is provided on a line connecting the locking portion 31 of the joint piece 3 and the lead-out portion 45 of the case 4, and the inner cable 21 a in the vicinity of the cable ends 22 a and 22 b locked to the locking portion 31. , 21b is a part where the inner cables 21a, 21b are extended from the joint piece 3 so as not to be damaged.
　そして、本実施形態では、図１および図２（ａ）に示されるように、幅狭部位３２ｂが、挿入部位３２ａから係止部位３２ｃに向かって、摺動方向に対して略垂直な方向にオフセットしたオフセット部Ｏｓを有している。このオフセットしたオフセット部Ｏｓにより、一度組み付けたインナーケーブル２１ａ、２１ｂが、より抜けにくくなるため、インナーケーブル２１ａ、２１ｂの組み付けがより容易になる。すなわち、挿入部位３２ａから挿入されたインナーケーブル２１ａは、図４（ｂ）に示す状態からケーブルエンド２２ａを支点として左側に倒される。このとき、オフセット部Ｏｓを通るインナーケーブル２１ａは、図２（ａ）に示されるように、組み付けられた状態のインナーケーブル２１ａ（図２（ａ）中に、２点鎖線で示している）が係止される係止部位３２ｃの軸Ｘに対して、軸Ｘに対して摺動方向に対して略垂直な方向（ジョイントピース３の幅方向）にずらされる。その後、図２（ａ）に２点鎖線で示されるように、インナーケーブル２１ａをオフセット部Ｏｓからジョイントピース３の幅方向に向けて再度ずらして、軸Ｘに沿うように係止部位３２ｃに係止させる。したがって、インナーケーブル２１ａが外れるためには、この動きと反対の動きをする必要があり、インナーケーブル２１ａに、軸Ｘに対してジョイントピース３の幅方向にインナーケーブル２１ａをずらす力が加わる必要がある。したがって、インナーケーブル２１ａ、２１ｂが係止部位３２ｃまで移動した後は、インナーケーブル２１ａ、２１ｂがジョイントピース３から抜けにくくなり、インナーケーブル２１ａ、２１ｂの組み付けがより容易となる。なお、上述したインナーケーブル２１ａの組み付け方はあくまで一例であり、本発明を限定するものではない。 In this embodiment, as shown in FIG. 1 and FIG. 2A, the narrow portion 32b extends in a direction substantially perpendicular to the sliding direction from the insertion portion 32a toward the locking portion 32c. The offset portion Os is offset. Due to the offset offset portion Os, the inner cables 21a and 21b once assembled are more difficult to be pulled out, so that the inner cables 21a and 21b are more easily assembled. That is, the inner cable 21a inserted from the insertion site 32a is tilted to the left from the state shown in FIG. 4B with the cable end 22a as a fulcrum. At this time, as shown in FIG. 2A, the inner cable 21a passing through the offset portion Os is an assembled inner cable 21a (indicated by a two-dot chain line in FIG. 2A). The axis X of the locking part 32c to be locked is shifted in a direction substantially perpendicular to the sliding direction with respect to the axis X (the width direction of the joint piece 3). Thereafter, as indicated by a two-dot chain line in FIG. 2A, the inner cable 21a is shifted again from the offset portion Os in the width direction of the joint piece 3, and is engaged with the locking portion 32c along the axis X. Stop. Therefore, in order to disengage the inner cable 21a, it is necessary to move opposite to this movement, and it is necessary to apply a force to the inner cable 21a to shift the inner cable 21a in the width direction of the joint piece 3 with respect to the axis X. is there. Therefore, after the inner cables 21a and 21b have moved to the locking portion 32c, the inner cables 21a and 21b are less likely to be detached from the joint piece 3, and the inner cables 21a and 21b are more easily assembled. The method of assembling the inner cable 21a described above is merely an example, and does not limit the present invention.
　また、オフセット部Ｏｓは、インナーケーブル２１ａ、２１ｂの抜けを抑制することができるように、挿入部位３２ａと係止部位３２ｃとの間で、摺動方向に対して略垂直な方向にオフセットしたものであれば、その形状は図２（ａ）に示す形状に限定されるものではなく、幅狭部位３２ｂを蛇行させたもの等、他の形状であっても構わない。 The offset portion Os is offset in a direction substantially perpendicular to the sliding direction between the insertion portion 32a and the locking portion 32c so that the inner cables 21a and 21b can be prevented from coming off. If so, the shape is not limited to the shape shown in FIG. 2A, and may be another shape such as a meandering narrow portion 32b.
