Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control cable and a cable end connecting device used for the control cable. More specifically, the present invention relates to a control cable used for connecting a transmission and an operating lever (shift lever) of an automobile, and a cable end connecting device used for the control cable.

[0002]

2. Description of the Related Art Push-pull control cables for connecting a manual transmission and an operating lever of an automobile include push-pull control cables 51 for shift operation and push-pull control cables for select operation, as shown in FIG. 52 and 2 are installed in one set. In FIG. 7, reference numeral 53 is a transmission side cable end connecting device, and reference numeral 54 is an operating lever side cable end connecting device. As shown in FIG. 8, each of the cables 51 and 52 includes a tube-shaped liner 56, a shield layer 57 provided around the liner, and a conduit 59 including a coating layer 58 provided on the outer periphery thereof, and the liner 56. The inner cable 60 is slidably inserted into the inside of the vehicle, and both ends thereof are connected to the operation lever and the transmission via the cable end connecting devices 53 and 54 of FIG.

As shown in FIG. 7, a general cable end connecting device has a casing cap 62 fixed to both ends of a conduit 59, and a guide pipe 64 provided on the casing cap 62 so as to be rotatable about two axes. , A guide rod 65 slidably provided in the guide pipe and connected to the inner cable 60.

When the above-mentioned two independent cables are used as one set, the two cables are pierced through the panel 66 which separates the engine room from the interior of the cabin. Therefore, two openings must be provided and the respective seals must be provided. I have to. Therefore, for example, the two cables 51 and 52 are preliminarily connected by one grommet 67, and the opening and the seal formed in the panel 66 are formed only at one place. However, even in this case, the cost of two parts, the assembly cost, and the cable installation cost are required, and it is difficult to reduce the weight because of the weight of two cables. Moreover, the grommet is mounted before the cable end connecting device is mounted. It is difficult to handle because it is necessary.

In order to solve such a problem, a transmission operating device (special feature) in which a conduit (or an inner cable) is used as a rotational force transmitting element to perform a shift operation and a select operation with one control cable Kaisho 58-19211
No. 8) is proposed. Further, a second conduit is further provided around the normal first conduit, and the inner cable and the first conduit are independently pushed and pulled, so that the shift operation and the select operation are transmitted by one cable as a whole. Transmission operating device (Japanese Patent Laid-Open No. 62-2381)
No. 20) is also proposed. On the other hand, although not limited to the transmission operating device, a pulling control cable in which two inner cords are inserted into one conduit (actually disclosed in Japanese Utility Model Laid-Open No. 54-8103
No. 5, Japanese Utility Model Publication No. 58-182013), and
Push-pull control cable (Japanese Patent Publication Sho 55-1785)
No. 0) is proposed.

[0006]

The device using the above-mentioned set of two cables is expensive, difficult to reduce in weight, and difficult to handle. Further, in the vicinity of the end, two or more wiring spaces are required to avoid mutual interference. On the other hand, in the above-mentioned device that uses the rotation of the conduit for transmitting the operating force, it is difficult to accurately transmit the operating stroke because the torsional rigidity of the conduit is low. In addition, if an attempt is made to secure sufficient torsional rigidity, the outer diameter of the conduit becomes large, which makes it difficult to install the conduit. Further, in the control cable in which the above-mentioned double conduit is provided, the outer diameter of the second conduit is extremely large, and in the input / output section, an operation space of twice the stroke or more is required in the axial direction of the cable. On the other hand, the conventional control cable in which two inner cords are housed in one conduit has a large cavity between the inner cord and the inner wall of the conduit, so that the stroke loss is large, and the inner cord is also pushed during the pushing operation. Buckling tends to occur, which is not practical. Further, since the control cable of Japanese Patent Publication No. 55-17850 has a flat cross section, it is difficult to install it.

The present invention can handle two or more control cables substantially as easily as one, the outer diameter of the conduit does not become so large, and a space for wiring and an input / output section is not required so much. In other words, the technical issue is to provide a practical control cable with less stroke loss and less buckling of the inner cable. Further, it is a technical object of the present invention to provide a compact cable end connecting device used for the control cable.

[0008]

The control cable of the present invention is flexible, having a continuous tubular armor layer and a plurality of liner accommodating holes provided inside the armor layer and adjacent to each other. A conduit including an intermediate member having the intermediate member, a liner accommodated in the liner accommodating holes of the intermediate member so as to be in close contact with each other, and an inner cord slidably accommodated in each liner of the conduit. .

The liner accommodating holes may be substantially communicated with each other in the lengthwise direction, or may be separated from each other without communicating. The armor layer may be a shield layer in which a plurality of metal wires are wound around the surface of the intermediate member in a loose spiral shape, and a coating layer may be provided on the outer peripheral surface of the shield layer. The control cable of the present invention can be used as a pulling control cable, or can be used as a pushing / pulling control cable by being configured so that the pushing / pulling operation of the inner cable can be performed. The intermediate member and the liner can be manufactured by extrusion molding a synthetic resin. Usually, the melting point of the intermediate member is higher than the melting point of the liner, but a material having a lower melting point can be used.

The cord end connecting device of the present invention has a bottomed cylindrical fixing portion fixed to the outer periphery of the end portion of the conduit at one end, and the inner cord inserting hole extends from the inner bottom portion of the fixing portion to the other end. And a casing cap having at least one receiving portion at the opening of the inner cable insertion hole at the other end, and a guide whose base end is rotatably supported around the two axes around the receiving portion. A pipe, a pipe retainer that holds the guide pipe on the other end side of the casing cap, and a rod-shaped element that is combined with the guide pipe and telescopically and that is connected to the casing cap and the end of the inner cable that is passed through the guide pipe. It consists of The receiving portion, the guide pipe, and the rod-shaped element are usually provided for the number of inner lines, but the number may be smaller than that.

When there are two inner cords, the inner cord insertion hole is a flat hole penetrating from the inner bottom portion to the other end side so as to gradually expand, and the other end side of the hole. You may form the receiving part which supports the base part of two guide pipes at the both ends of the flat opening part. However, the inner cord insertion holes may be provided by the number of inner cords. The rod-shaped element can be composed of a pipe portion slidably provided on the surface of the guide pipe, an inner cord fixing portion provided at the tip of the pipe portion, and a connecting portion to a mating member. . The rod-shaped element may be a rope end rod slidably provided inside the guide pipe.

[0012]

Since the control cable of the present invention accommodates a plurality of inner cables in one conduit, the handling at the time of wiring is the same as that of one cable, and only one grommet is required. The function is the same as multiple control cables. That is, when one inner cable is pulled or pushed, only the other end of the inner cable is pulled in or out. Thereby, the operation can be individually transmitted to the other end side. Two or more inner cords separately,
And they can be operated at the same time. The inner cable is housed inside the liner, and the liner is inserted into the liner housing hole of the intermediate member.Therefore, the operation feeling such as sliding resistance of the inner cable is almost the same as that of the independent control cable. Absent.

Furthermore, since the intermediate member is housed inside the armor layer, there is no cavity inside the armor layer, and therefore, even when the control cable is bent and routed, the conduit is unlikely to break, and the inner cable is not broken. Buckling can be sufficiently prevented. The outer diameter of the conduit of the control cable of the present invention is thicker than the conduit for the inner cable used, but it is not necessary to increase the torsional rigidity like the conduit for transmitting the rotational force, and the conduit is doubled. Bending rigidity is much lower than that provided. Therefore, the installation is relatively easy. Moreover, since the inner cord only accommodates a plurality of thin ones, the bending rigidity in the assembled state is unexpectedly low, and of course, the conduit having the same outer diameter and one inner cord inserted therein are used. Lower than the control cable.

If the liner accommodating holes are substantially communicated with each other in the lengthwise direction, the work can be easily performed even when the liner is inserted later, the intermediate member itself can be easily manufactured, and the control cable can be easily manufactured. The overall bending stiffness is even lower. When the armor layer is composed of a shield layer in which a plurality of metal wire rods are wound in a loose spiral shape on the surface of the intermediate member, and a coating layer is provided on the outer peripheral surface of the shield layer, the control cable has sufficient flexibility. It is possible to fully support the force in both directions of pushing and pulling the inner rope while maintaining it. Since the push-pull control cable has higher rigidity than the pull-pull control cable and is more difficult to install, the present invention is more advantageous when used for the push-pull control cable. When the melting point of the intermediate member is lower than the melting point of the liner, the intermediate member can be extruded and molded on a plurality of liners.

In the cord end connecting device of the present invention, the fixing portion of the casing cap is fixed to the end portion of the conduit of the control cable having a plurality of inner cords, and the end portion of the inner cord protruding from the liner is rod-shaped. Used by fixing to a member. If the rod-shaped member is pushed and pulled in this state, the rod-shaped member is guided by the guide pipe and linearly slides, and the inner rope can be pushed and pulled. Conversely, if you push and pull the other end of the inner cable,
The rod-shaped member is guided by the guide member and slides back and forth. Therefore, the rope end connecting member can be used as both an input section and an output section. When the number of receiving parts, guide pipes, and rod-shaped elements is equal to the number of inner lines, all the inner lines can be input or output at the end of the conduit.
When the number of inner cords is smaller than the number of inner cords, the inner cords not connected to the rod-shaped element may be guided by another conduit or pipe from the opening of the inner cord insertion hole. In that case, a control cable for branching the inner cable from the middle can be obtained.

In the case of two inner cords, the inner cord insertion hole is one flat hole penetrating from the inner bottom portion so as to gradually expand toward the other end side, and the other end side of the hole. When the receiving portions are formed at both ends of the opening portion, the free ends of the two inner cords can be arranged largely apart from each other, and the guide pipe can easily rotate about the two axes around the receiving portion. Therefore, it is easy to connect with the input lever and the output lever. When the rod-shaped element is composed of a pipe portion slidably provided on the surface of the guide pipe, an inner rope fixing portion provided at the tip of the pipe portion, and a connecting portion to a mating member, Since the base ends of the pipes can be arranged close to each other, a thin conduit can be adopted, and the rope end connecting device can be made compact.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION Next, preferred embodiments of a control cable and a cable end connecting device of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an essential part showing an embodiment of a control cable of the present invention, FIG. 2 is a sectional view of a conduit of the control cable, and FIGS. 3 and 4 are each an embodiment of a cable end connecting device of the present invention. FIG. 5 is a partially cutaway perspective view showing a state before assembling thereof, and FIG. 5 is a partially cutaway plan view showing an embodiment of a transmission cable adopting a control cable and a cable end connecting device of the present invention. FIG. 6 is a plan sectional view showing another embodiment of the rope end connecting device of the present invention.

The control cable A shown in FIG.
The push-pull control cable includes a conduit 1 and two inner cords 2 and 2 slidably provided therein. As shown in FIGS. 1 and 2, the conduit 1 is an intermediate member having a continuous tubular armor layer 3 and two liner accommodating holes 4 and 4 which are provided inside the armor layer and which are adjacent to each other. 5 and a liner 6 accommodated in the liner accommodating holes 4 of the intermediate member so as to be in close contact with each other. The two inner cords 2, 2 are housed in each liner 6, 6.

In this embodiment, the armor layer 3 is formed as a shield layer in which a plurality of metal wires 7 are wound around the surface of the intermediate member 5 in a loose spiral shape, and the outer peripheral surface of the shield layer is covered with a coating layer. 8 are provided. Armor layer 3 consisting of a shield layer
As the coating layer 8 itself, one used in a conventionally known push-pull control cable can be adopted. For example, a metal wire such as a hard steel wire having an outer diameter of about 0.8 mm can be used as the metal wire for the shield layer. Further, the shield layer may be composed of a wire material made of synthetic resin such as fiber reinforced resin (FRP) wire. Further, in the case of the pulling control cable, a spring type armor layer in which one thick metal wire is spirally wound can be adopted. Further, the inner cable for the push-pull control cable and the inner cable for the pull-control cable may be mixed in one control cable, and in that case, an armor layer for the push-pull control cable is adopted. The coating layer 8 can be formed by extruding a thermoplastic resin such as polyethylene, polypropylene, polyamide, or polyester elastomer on the shield layer.

The intermediate member 5 is peculiar to the control cable of the present invention, and a thermoplastic resin such as polypropylene (PP), polyethylene (PE), polyamide (PA) or polyvinyl chloride (PCV) is shown in FIG. like,
It is extrusion molded into a circular cross-sectional shape having a liner receiving hole 4 in the center. In this embodiment, the liner accommodating hole 4 has a so-called spectacle-like shape in which two holes 4a and 4b having a circular cross section are communicated with each other at adjacent portions. By connecting the liner receiving holes to each other in this way,
There is an advantage that the outer shape of the intermediate member 5 can be reduced. However, in some cases, the liner receiving holes may be separated from each other by a partition wall or the like. Further, when accommodating three to four or more inner cords, the number of liner accommodating holes may be increased accordingly. Also in that case, they may be communicated with each other or may be separated.

As the liners 6, 6, those used in the conventionally known push-pull control cable can be used as they are. For example, polybutylene terephthalate (PBT), polyacetal (POM), polytetrafluoroethylene (PTFE), A product obtained by extruding polyethylene (PE) or the like into a tube shape may be used.
The liner 6 usually has a diameter of 3 to 4 mm and a thickness of 0.3 to
It is about 0.8 mm.

The intermediate member 5 and the liner 6 are usually formed separately from each other and continuously molded, cut into a length suitable for the purpose of use, and then the liner 6 is inserted into the liner accommodating hole 4.
Insert However, as in the case where the material of the liner 6 is polytetrafluoroethylene (PTFE) and the material of the intermediate member 5 is polypropylene (PP), the melting point of the material of the intermediate member 5 is lower than that of the liner 6. In this case, the intermediate member 5 may be extruded and molded on the liner 6, 6 which is molded in advance.

The inner cords 2 and 2 are conventionally known inner cords for push-pull control cables, and are one steel wire, a plurality of steel wires twisted together, and about 15 core wires around one core wire. It consists of a thin steel wire wound around. A synthetic resin coating layer may be provided on the outer circumference of the steel stranded wire or the like.

In the control cable A having a plurality of inner cords constructed as described above, one end side of each of the two inner cords 2, 2 can be operated independently, and the operation force can be transmitted to the other end side. That is, when one of the inner ropes 2 is pushed and pulled, the other inner rope is stationary, and when the other inner rope is pushed and pulled, one inner rope is stationary. It is also possible to push and operate one inner cord while pushing the other inner cord, or to pull one of the inner cords and then pull the remaining inner cords. Furthermore, both inner cords can be pushed or pulled simultaneously. Moreover, manipulating one inner cord does not affect the other inner cord at all.

In this way, the control cable A has substantially the same function as when two ordinary control cables are arranged in parallel. Furthermore, although it is slightly thicker than the case of bundling two control cables, it is substantially in the form of one control cable, so it can be used for parts management, wiring work, and grommet and its The seal may be handled in substantially the same manner as in the case of one control cable. Therefore, compared to the case of using two control cables, it is possible to reduce the parts cost, installation and installation cost, etc., and to reduce the weight of parts and further save the installation space and the input / output section space. You can Since the inner cord accommodates a plurality of thin cords, the bending resistance is directional depending on the case. Therefore, when the installation is performed three-dimensionally, as in the case of bending in the vertical direction and then in the horizontal direction, the installation may be performed with some twist.

An embodiment of the rope end connecting device of the present invention will be described below with reference to FIGS. A cable end connecting device B shown in FIGS. 3 and 4 includes a casing cap 10 fixed to an end portion of a conduit 1 of a control cable A, and a rod-shaped element 11 connected to end portions of two inner cables 2 and 2, respectively. , 11
And guide pipes 12, 12 that slidably guide each rod-shaped element and are rotatably connected to the casing cap 10, and a pipe retainer 13 that holds these guide pipes with respect to the casing cap 10. Has been done.

The outer shape of the casing cap 10 is a conventional one.
The casing cap is substantially the same as the casing cap of the control cable for the inner cable, and has a bottomed cylindrical fixing portion 14 fixed to the outer periphery of the conduit 1 by caulking, and the casing cap 10.
It is provided with a flange portion 15 and an annular locking groove 16 formed on the outer periphery of the central portion for attaching itself to a mating member. Further, a receiving portion 17 for supporting the base end of the guide pipe 12 rotatably around two axes like a ball socket joint is formed at the end portion on the opposite side (tip end side) of the fixing portion 14. An inner cable insertion hole 18 extends longitudinally between the inner bottom of the receiving portion 17 and the inner bottom of the fixing portion 14. The casing cap 10 may be a zinc die-cast product or the like as in the conventional case.

In the present embodiment, the inner cable insertion hole 18 has the fixed portion 1
It is a flat hole with an oval cross section that gradually expands from the 4 side toward the tip side. As shown in FIG. 4, the receiving portion 17 is a stepped portion having a spectacle-shaped or oval-shaped cross section that surrounds the opening of the inner cable insertion hole 18. In this way, the inner cable insertion hole 18
By gradually increasing the shape, the inner cords 2, 2 are brought closer to each other and the diameters of the conduit 1 and the control cable A are kept small, while increasing the distance between the two guide pipes 12 and the rod-shaped elements 11 on the tip side. Therefore, the swing space of the guide pipe 12 can be sufficiently secured. Further, since the inner cord insertion hole 18 is configured to allow the two inner cords 2 and 2 to pass through with one hole, it is easy to process. However, one inner cable insertion hole may be provided for each inner cable 2, 2 and the receiving portion 17 may be independently provided for each inner cable 2, 2.

The guide pipe 12 is a thin metal pipe provided with a spherical enlarging portion 19 by bulging at the end and a synthetic resin coating 20 around the tip side. The synthetic resin coating 20 can be manufactured, for example, by covering a surface of a metal pipe with a stretched and formed tubular film of polyolefin, fluoropolymer, or the like and heat-shrinking the film. The inner diameter of the guide pipe 12 is set so that the inner cable 2 can be slidably guided without buckling.
The guide rod is not housed in the inside unlike a general rope end connecting device.

That is, in this embodiment, the rod-shaped member 11 having the pipe portion 21 having the inner periphery that slides with the outer periphery of the guide pipe 12 is adopted instead of the normal guide rod. The rod-shaped member 11 is composed of a pipe portion 21 made of a thin metal pipe, a metallic cylindrical inner cord fixing portion 22 provided at the tip of the pipe portion 21, and a connecting portion 24 for connecting with a ball joint 23 or the like. ing. The end portion of the inner cable 2 is inserted into the inner hole 25 of the inner cable fixing portion 22 and fixed by being caulked from the outer periphery to be integrated. A male screw 26 is formed on the connecting portion 24. In this way the guide pipe 1
A rod-shaped member 1 that is telescopically combined with the outer periphery of 2
By adopting 1, the thickness of the guide pipe 12 can be reduced. Further, as a result, the receiving portions 17 for receiving the two guide pipes 12 can be provided in a small area, and the rope end connecting device B can be made compact.

Even if the size of the control cable A is the same, the space of the receiving portion 17 can be increased by extending the casing cap 10 to the tip side to some extent. Therefore, if necessary, for example, a conventionally known telescopic structure (see FIG. 7) in which a guide rod is slidably inserted in a guide pipe can be adopted.

In the case of this embodiment in which a plurality of receiving portions 17 are provided at the tip of the casing cap 10, the tip of the casing cap is reduced in diameter like a conventional casing cap having one receiving portion. It is difficult to hold the enormous part of the guide pipe. Therefore, in this embodiment, the pipe retainer 13 manufactured separately from the casing cap 10 is used. The pipe retainer 13 is, for example, a bottomed tubular member made of synthetic resin, has an engagement protrusion 28 that engages with an engagement groove 27 formed in the casing cap 10 on the inner periphery of the opening, and an inner protrusion 29 on the bottom 29. Two holes 30, 30 are formed to insert the ropes 2, 2. Each of the two holes 30 has a tapered shape that widens toward the tip side so as to allow the guide pipe 12 to rotate about two axes (swivel motion). In the embodiment of FIG. 3, the casing cap 10
Although the liner 6 of the control cable A is extended to the inside of the inner cable insertion hole 18, the liner 6 may be cut at the end of the conduit 1.

In the rope end connecting device B constructed as described above, when the connecting portion 24 of one rod-like element 11 is connected to an operating lever or the like and pushed and pulled, the corresponding inner rope 2 follows and reciprocates. Operated. In that case, since the guide pipe 12 is supported by the receiving portion 17 so as to be rotatable about two axes, it can be followed even if the connecting portion 24 with the operation lever or the like moves laterally, and the inner cable 2 Is smoothly guided in the guide pipe 12. Conversely, when the other end side of the inner cable 2 is pushed and pulled, the rod-shaped element 11 is reciprocated. Also in this case, the swinging of the guide pipe 12 can absorb the lateral movement of the mating member.
In this way, the cable end connecting member B can be used on both the input side and the output side. Normally, two rod-shaped elements 11, 11 of one rope end connecting device B are used as one set on either the input side or the output side, but one rod-shaped element 11 is used on the input side, Other rod-shaped elements can also be used on the output side.

FIG. 5 shows the control cable A of FIGS.
3 shows a transmission cable C having the cable end coupling devices B and B of FIGS. 3 to 4 attached to both ends thereof. The transmission cable C is for transmitting shift operation and select operation of a manual shift lever provided in a driver's seat of an automobile to a shift shaft and a select shaft of a transmission in an engine room. That is, conventionally, the control cable is composed of two independent control cables arranged in parallel as shown in FIG. 6, but in the present embodiment, one control cable having the same function as the two cables is provided. A and its control cable A 2
It is composed of a cable end connecting device B that inputs and outputs the inner cable 2 of the book.

Since this control cable has substantially one control cable A, it suffices to provide only one through hole in the partition wall between the driver's seat and the engine room, and one grommet or seal is required. Good. In addition, installation work can be done with one control cable. And the rope end connection device B
Since the rod-shaped elements 11 are separated from each other at their tip sides, the work of connecting the shift lever on the input side and the shift shaft of the transmission on the output side is easy.

In the above embodiment, the control cable A employing two inner cords has been described, but the number of inner cords is not limited to two, and three or four or more may be used. In that case, the cost reduction effect is further enhanced. Further, although the push-pull control cable is basically explained in the above-mentioned embodiment, the present invention can be adopted as the pull control cable, or the push-pull cable and the pull cable can be combined. If necessary, insert an electric cord into one or two liner housing holes.
It is also possible to route and wire by combining a control cable and an electric cable.

Further, in the embodiment of the rope end connecting device B described above,
Two inner cords 2 are taken out from the end of the conduit 1 and are respectively connected to the rod-shaped members 11. However, as shown in FIG. 6, only one inner cord 2a is connected to the rod-shaped element 11 and the other inner cords 2a are connected to each other. The cord 2b may be inserted again into the conduit 31 for one inner cord. Reference numeral 32 is a conduit fixing portion provided on the pipe retainer 13. The free end of the conduit 31 may be connected to a normal one cable end connecting device for inner cable (see FIG. 7). As described above, the cable end connection device of the present invention can also be used as a branching device in a control cable for a plurality of inner cables.

[0038]

Since the control cable of the present invention accommodates a plurality of inner cables in a single conduit, it has the same function as when a plurality of control cables are adopted, and moreover, a plurality of cables. Since the number of parts is smaller than that in the case of using, it is possible to reduce parts cost, management cost, and installation cost. Also, only one grommet or seal is required when passing through the isolation wall. Furthermore, since the inner cord is guided relatively closely by the intermediate layer and the liner, stroke loss is small and buckling of the inner cord is unlikely to occur.

If the cable end connecting device of the present invention is adopted, the input device or output device of the plural inner cable control cables or the branching device can be made compact.

If the liner accommodating holes are substantially communicated with each other in the lengthwise direction, the work can be easily performed even when the liner is inserted later, the intermediate member itself can be easily manufactured, and the control cable can be easily manufactured. The overall bending stiffness is even lower. When the armor layer is composed of a shield layer in which a plurality of metal wire rods are wound in a loose spiral shape on the surface of the intermediate member, and a coating layer is provided on the outer peripheral surface of the shield layer, the control cable has sufficient flexibility. It is possible to fully support the force in both directions of pushing and pulling the inner rope while maintaining it. Since the push-pull control cable has higher rigidity than the pull-control cable and it is more difficult to install it,
The present invention is more advantageous when applied to a push-pull control cable. When the melting point of the intermediate member is lower than the melting point of the liner, the intermediate member can be extruded and molded on a plurality of liners.

In the case of two inner cords, the inner cord insertion hole is a flat hole penetrating from the inner bottom portion so as to gradually expand toward the other end side, and the other end side of the hole is formed. When the receiving portions are formed at both ends of the opening portion, the free ends of the two inner cords can be arranged largely apart from each other, and the guide pipe can easily rotate about the two axes around the receiving portion.

In this embodiment, the armor layer 3 is formed as a shield layer in which a plurality of metal wire rods 7 are wound around the surface of the intermediate member 5 in a loose spiral shape, and the outer peripheral surface of the shield layer is covered with a coating layer. 8 are provided. As the armor layer 3 made of a shield layer and the coating layer 8 itself, those used for a conventionally known push-pull control cable can be adopted. For example, a metal wire such as a hard steel wire having an outer diameter of about 0.8 mm can be used as the metal wire for the shield layer. Further, the shield layer may be composed of a wire material made of synthetic resin such as fiber reinforced resin (FRP) wire. Further, in the case of the pulling control cable, a spring type armor layer in which one thick metal wire is spirally wound can be adopted. Further, the inner cable for the push-pull control cable and the inner cable for the pull-control cable may be mixed in one control cable, and in that case, an armor layer for the push-pull control cable is adopted. Coating layer 8
Polyethylene, polypropylene, polyamide, may be formed by extruding a thermoplastic resin such as polyester elastomer on the shield layer.

The intermediate member 5 is specific to the control cable of the present invention, polypropylene (PP), polyethylene (PE), polyamide (PA), thermoplastic resins such as polyvinyl chloride (P VC) in FIG. 2 As shown, it is extruded into a circular cross-sectional shape having a liner receiving hole 4 in the center. In this embodiment, the liner accommodating hole 4 has a so-called spectacle-like shape in which two holes 4a and 4b having a circular cross section are communicated with each other at adjacent portions. By connecting the liner accommodating holes to each other in this manner, there is an advantage that the outer shape of the intermediate member 5 can be reduced. However, in some cases, the liner receiving holes may be separated from each other by a partition wall or the like. Further, when accommodating three to four or more inner cords, the number of liner accommodating holes may be increased accordingly. Also in that case, they may be communicated with each other or may be separated.

In the rope end connecting device B constructed as described above, when the connecting portion 24 of one rod-like element 11 is connected to an operating lever or the like and pushed and pulled, the corresponding inner rope 2 follows and reciprocates. Operated. In that case, since the guide pipe 12 is supported by the receiving portion 17 so as to be rotatable about two axes, it can be followed even if the connecting portion 24 with the operation lever or the like moves laterally, and the inner cable 2 Is smoothly guided in the guide pipe 12. Conversely, when the other end side of the inner cable 2 is pushed and pulled, the rod-shaped element 11 is reciprocated. Also in this case, the swinging of the guide pipe 12 can absorb the lateral movement of the mating member.
In this way, the cable end connection device B can be adopted on both the input side and the output side. Normally, two rod-shaped elements 11, 11 of one rope end connecting device B are used as one set on either the input side or the output side, but one rod-shaped element 11 is used on the input side, Other rod-shaped elements can also be used on the output side.
