Description

  The present invention relates to a control cable support device. More specifically, the engine room terminals such as push-pull control cable for automatic transmission operation (hereinafter referred to as AT cable) and push-pull control cable for manual transmission operation (hereinafter referred to as MT cable) are shifted. The present invention relates to a control device for a control cable having an anti-vibration structure suitable for supporting vibration so as not to be transmitted to a lever side, and a control cable with a support device using the same.

JP 2004-84684 A

  As shown in FIG. 8, the AT cable 100 generally includes a terminal support device 120 at an end portion on the transmission side and a terminal support device 110 at an end portion on the shift lever side. The transmission of vibration from the transmission to the shift lever is prevented. The terminal support devices 110 and 120 have a rubber cap mounted on a casing cap that holds a control cable terminal. In particular, the terminal support device 120 on the transmission side has a high anti-vibration performance. This is because if the terminal support device 110 on the shift lever side has a high anti-vibration performance, a loss occurs in the stroke of the inner cable and the stable operability of the AT cable is impaired.

  The terminal support device 110 shown in FIG. 9a includes a casing cap 111 that is caulked to the end of the conduit T, a vibration isolating rubber 113 that is attached around a flange 112 provided at one end of the casing cap, and the vibration isolating rubber 113. Housings 114a and 114b. The housings 114a and 114b are fixed to each other by outsert-molding a bottom cylindrical rear portion 114b into a cylindrical front portion 114a to form a concave / convex fitting structure between the annular groove and the annular projection. A recess 117 is formed at the tip of the anti-vibration rubber 113 to support the swollen spherical portion 116 of the guide pipe 115 so as to freely swing. An annular groove 119 for attaching to the mating member 118 is formed in the front portion 114a of the housing. Thus, on the mission side, the guide pipe 115 is flexibly held at the tip of the anti-vibration rubber 113, but the flexibility is inferior at the portion holding the conduit on the opposite side. This is because if both sides of the anti-vibration rubber 113 are made flexible, the stroke of the inner cable is likely to be lost, and the stable operability of the AT cable is impaired.

  A terminal support device 120 shown in FIG. 9b has a tubular casing cap 122 having a conduit fixing portion 121 for fixing the end of the conduit T of the control cable at one end, a flange 123 at the center portion 122a, and the casing cap of the casing cap. Ring-shaped dampers 124 and 125 arranged on the outer periphery so as to contact the front and rear of the flange 123, and a first holding plate 126 and a first holding plate 126 that pressurize and hold these dampers on the flange 123 side without restricting the periphery. 2 holding plate 127. In FIG. 9b, there is a gap between the first holding plate 126 and the second holding plate 127, but at the time of installation, the dampers 124 and 125 are pressed and held because they are fastened by bolts.

  In order to support the control cable between the engine and the shift lever, and to attenuate the vibration transmitted from the engine side to the shift lever side, the support structure uses a soft member as much as possible so that the vibration is easily damped. It ’s better not to fix it too firmly. However, if the cable is not fixed firmly to some extent, the stroke loss during operation of the inner cable will increase, making it difficult for displacement to be transmitted from the shift lever side to the engine side, resulting in displacement (shift displacement) between the shift lever and the transmission. There is a fear. In this way, vibration attenuation and stroke loss (performance) conflict. Therefore, as in the prior art, various support structures have been studied in order to satisfy these two actions at the same time.

  For example, in the terminal support device 120 shown in FIG. 9b, the elastic member is floating supported as firmly as possible so as to solve the above-described problem. In this case, since the side surface of the elastic member is not covered with the socket, it is easily elastically deformed radially outward with respect to the axial pressure, and the elastic member is firmly held while maintaining the original elasticity. be able to.

  Here, there are the following unsolved problems as factors causing vibration damping. That is, the support device is usually used with a control cable. The control cable is not in a straight line state due to the structure of the vehicle body at the time of routing, but is bent to such an extent that it does not affect the performance of the control cable. Therefore, a reaction force is applied to the terminal support device in which the end portion of the conduit is held to return the conduit to a straight state. The reaction force elastically deforms (initial displacement) the elastic member of the terminal support device, and the amount of displacement of the elastic member necessary for vibration damping is lost. Therefore, the vibration damping performance is reduced. The state in which the control cable is not attached straight to the support device but is attached to the support device at an angle is hereinafter referred to as a “twisted state” (two-dot chain line in FIG. 2).

  Therefore, the present invention provides a control cable support device that can solve the above-described problems and achieves a vibration-proofing effect with a simple structure even when the cable is in a twisted state, and a control cable with a support device using the support device. It is an issue.

Support equipment control cable of the present invention has a conduit retaining portion end of the conduit of the control cable is fixed to the rear end, a tubular casing cap having a flange on the outer periphery, the flange of the casing cap An elastic member having a hook-like portion surrounding the portion including the flange and covering the periphery of the flange; and a portion including the flange of the casing cap and the elastic member so as to surround the elastic member; A cylindrical socket having an inner wall before and after elastically sandwiching in the axial direction, and a cylindrical socket provided with an attachment portion to a mating member, so that the elastic member abuts on the front and rear inner walls of the socket A plurality of protrusions are formed on the front and rear surfaces of the substrate so as to be spaced apart from each other.

In such a control cable support device, the elastic member has a cylindrical portion that extends back and forth from the bowl-shaped portion and covers the casing cap, and the sockets are respectively continuous from the lower ends of the front and rear inner walls. A plurality of cylindrical small-diameter portions surrounding the outer periphery, and arranged at intervals on the outer periphery of the cylindrical portion of the elastic member so as to contact the inner peripheral surface of the small-diameter portion of the socket what number of projections are formed is not preferable. Further, what it is not preferable that the projections of the front and rear surfaces of the flange portion is formed on the protrusion extending radially outward. Further, the elastic member has an annular rib projecting from substantially the center of the outer periphery of the bowl-shaped part, and the socket has a cylindrical large-diameter part that is continuous from the upper end of the inner wall and surrounds the outer periphery of the bowl-shaped part. and which, what is not preferable that the annular rib of the inner peripheral surface and the flange portion of the large diameter portion of the socket is in contact with. In addition, the cylindrical portions before and after the elastic member have an annular piece formed outward from the peripheral edge of each tip portion, and the annular piece and the inner peripheral surface of the small diameter portion of the socket are in contact with each other. contact thing is not preferable.

The flange of the casing cap, not preferred is what is formed in a tapered shape in which the thickness narrows towards the outside.
Further, the material of the elastic member is ethylene-propylene-diene copolymer rubbers, and the dynamic magnification is not preferred those in which 1.2 to 1.5.

Supporting device with control cable of the present invention is characterized in that it consists a control cable to be passed to the transmission side and the shift lever side, a support device of the above-mentioned control cable arranged at both ends of the conduit.

Support equipment control cable of the present invention, when the conduit of the control cable is held in the conduit holder, a reaction force due to wiring which generally curved from the conduit, respectively from the front and back of the flange portion of the elastic member shaft A plurality of protrusions extending in the direction are supported by elastically contacting the front and rear inner walls of the socket. That is, the protruding portion is elastically deformed and displaced, but the elastic member as a whole is not accompanied by a large displacement, so that it can be assembled with the ability to attenuate vibration isolation. Therefore, even if it is attached at an angle (even if it is in a twisted state), it has a high anti-vibration performance.
Further, since the anti-vibration performance is improved by forming the protrusion that supports the twisted state, there is almost no stroke loss accompanying the improvement of the anti-vibration performance.
Furthermore, vibrations in the axial direction of the control cable can also be attenuated by bending the front and rear projections of the bowl-shaped portion, so that the vibration isolation performance is high.

In such a control cable support device, the elastic member has a cylindrical portion that extends back and forth from the bowl-shaped portion and covers the casing cap, and the socket is continuous from the lower end of the inner wall and surrounds the outer periphery of the cylindrical portion. A plurality of protrusions spaced apart from each other are formed on the outer periphery of the cylindrical portion of the elastic member so as to contact the inner peripheral surface of the small diameter portion of the casing cap. In that case , in addition to the protrusion of the hook-shaped portion described above, the protrusion formed on the surface of the cylindrical portion supports the reaction force caused by the curvature of the conduit by elastically contacting the small-diameter portion of the socket. The anti-vibration performance can be improved without increasing the stroke loss.

Also, vibration-proof projections of the front and rear surfaces of the flange portion is if it is formed on the protrusion extending radially outward, the support device, at any angle, be a twist state, a stable It can be equipped with performance.
Further, the elastic member has an annular rib extending in a radial direction from a substantially center of the outer periphery of the bowl-shaped portion, and the socket is continuous from the upper end of the inner wall, and has a cylindrical large-diameter portion surrounding the outer periphery of the bowl-shaped portion. has, that is if the annular rib of the inner peripheral surface and the flange portion of the large diameter portion of the cable song cap is in contact with, it is possible to waterproof the interior of the socket by its ribs, and the ribs The entire cylindrical portion of the elastic member or the entire elastic member can be bent around the center. Therefore, the rib itself is not easily elastically deformed, can continue to exhibit waterproof performance, and hardly affect the deflection of the entire elastic member.

Furthermore, the front and rear cylindrical portions of the elastic member have an annular piece formed outward from the peripheral edge of each tip portion, and the annular piece and the inner peripheral surface of the small-diameter portion of the socket are in contact with each other. If contact can be sealed so as not water entering into the socket.
Moreover, when the flange of the said casing cap is formed in the taper shape which thickness decreases toward an outer side, the load by a prying state is hard to be transmitted to an elastic member from a taper-shaped flange.
In addition, when the elastic member is made of ethylene / propylene / diene copolymer rubber and has a dynamic magnification of 1.2 to 1.5, even if it is used in a high temperature environment, it is vibration proof. Can be demonstrated.

Supporting device with control cable of the present invention, the control cable to be passed to the transmission side and the shift lever side, since composed of a support device of the above-mentioned control cable arranged at both ends of the conduit, the stroke loss is small, High anti-vibration performance. Further, it can be handled as one part, and is easy to assemble or transport.

  Next, an embodiment of a control cable support device of the present invention will be described with reference to the drawings. 1 is a partial sectional side view showing an embodiment of a control cable support device of the present invention, FIG. 2 is a partial side sectional view showing an embodiment of an AT cable using the support device of FIG. 1, and FIG. 3 is an elastic member. 4a is a schematic perspective view showing the elastic member, FIG. 4b is a schematic cross-sectional view taken along the line II of FIG. 1, and FIGS. 5a and 5b show the spring characteristics of the support device in the prying state. FIGS. 6A and 6B are diagrams showing a soundproofing effect due to vibration attenuation of the support device, and FIG. 7 is a diagram showing another embodiment of the elastic member and the socket.

  First, how the control cable support device A (hereinafter referred to as support device A) is used will be described with reference to FIG. The support device A for the AT cable 10 shown in FIG. 2 is attached to an end portion on the transmission side of a conduit T of a control cable connecting the transmission and the shift lever. In this embodiment, the support device A is also used at the end portion on the shift lever side. However, the support device on the shift lever side is slightly different in the shape of the socket depending on the mounting position. Since it is almost the same as the supporting device A, the description thereof is omitted.

  A guide pipe 12 is arranged on the transmission side (left side in FIG. 2) of the support device A, and a rod 11 connected to the transmission is arranged inside the guide pipe 12. The end portion of the inner cable P of the control cable is fixed to the end portion of the rod 11 and is slidably supported by the guide pipe 12. On the other hand, a conduit T that slidably accommodates the inner cable P and guides it toward the shift lever is attached to the other end side of the support device A (the right side in FIG. 2).

  The support device A shown in FIG. 1 includes a cylindrical casing cap 1 having a flange 1a near the center, an elastic member 2 covering an outer periphery including the flange 1a of the casing cap 1, and a flange 1a of the casing cap 1. It comprises a socket 3 that accommodates the part to be contained and the elastic member 2 and is provided with a mounting portion 3a to the mating member. A nut 3e is screwed in front of the attachment portion 3a. When attaching the supporting device A to the mating member, the nut 3e is loosened, and a bracket (not shown) having a U-shaped opening is inserted between the nut 3e and the attaching portion 3a. Next, the nut 3e is screwed so as to sandwich the bracket, and the support device A is fixed to the counterpart member.

  In addition, the “squeezed state” in the present application refers to a state in which the conduit T is fixed to the support device A at an angle α as indicated by a two-dot chain line in FIG. That is, the conduit T is preferably routed in a straight line inside the vehicle body, but is actually routed in an appropriate curved state. Therefore, the end of the conduit T applies a force to return straight to the conduit holding portion 1b of the casing cap. When such a force is applied to the conduit holding portion 1b, the socket 3 having the attachment portion 3a to the vehicle body is left as it is, the casing cap 1 inside thereof is displaced from the axis of the socket 3, and the elastic member 2 is elastically deformed. The initial displacement is given to the elastic member 2. Such a state is called a prying state. Note that the angle α of the twist shown in FIG. 2 is for obtaining an actual measurement value as will be described. For this reason, when the angle is viewed from the top and FIG. 2 is viewed from the side, the axes of the conduit T and the socket 3 are not off.

  The rear portion of the casing cap 1 is a thin-walled cylinder, and is a conduit holding portion 1b that fixes and holds the conduit T by caulking from the outer periphery toward the center. The casing cap 1 has a central hole 3f through which the inner cable passes, along the axis. On the other hand, at the front end, the spherical portion 12a at the end of the guide pipe 12 is inserted, and the spherical root vicinity 1c is crimped to such an extent that the rotation of the spherical portion is not hindered and cannot be removed (see FIG. 1).

  From here, it demonstrates using FIG. 3 and FIG. The elastic member 2 surrounds the flange 1a so as to cover the flange 1a, and the cylindrical portion 2a extends outward in the axial direction from the front and rear of the flange 2b and covers the cylindrical portion of the casing cap 1. 2a. The elastic member 2 can be manufactured from a rubber-like polymer elastic body such as natural rubber, synthetic rubber, and synthetic resin elastomer, and ethylene / propylene / diene copolymer synthetic rubber (EPDM) is preferable. The rubber hardness is preferably about JIS Hs 40 ° to 60 °, and more preferably about Hs 45 ° to 55 °.

  First, the flange portion 2b of the elastic member 2 has a thick flange shape or a substantially cylindrical shape. The flanged portion 2b is a portion that mainly attenuates vibrations from the rod 11, the flange 1a of the casing cap 1, the guide pipe 12, and the like. The radius r of the bowl-shaped part 2b is 11 to 13 mm, preferably 11.5 to 12.5 mm. Moreover, the width | variety of front and back is 12-15 mm, Preferably it is 13-14 mm. In addition, the flange portion 2b is provided with an annular rib 2d extending outward from the vicinity of the center in the front-rear direction of the outer periphery in the radial direction. The rib 2d is in contact with the inner peripheral surface of the socket 3 so that water does not enter the conduit T through the gap between the socket 3 and the elastic member 2. Further, when annular pieces 2e, 2e are provided at the front ends of the front and rear cylindrical portions 2a, 2a (see FIG. 7). The outer casing 1b on the shift lever side is greatly twisted during routing, and water can be prevented from entering through the gap between the small diameter portion 3b of the socket on the shift lever side and the cylindrical portion 2a of the casing cap. The annular piece 2e of the cylindrical portion 2a may be formed as a ridge or tapered so as to incline outward toward the tip.

  The length L from the tip of the flange 1a of the casing cap 1 of the tubular part 2a to the front end of the front tubular part 2a (or the length from the rear end of the rear tubular part 2a) is 11 to 13 mm. The thickness is preferably 11 to 12 mm. The length L of the cylindrical portion 2a and the radius r of the flange portion 2b are preferably substantially the same, but the length L of the cylindrical portion can be longer than the radius r of the flange portion. . In this case, the ratio L: r of the length to the radius is about 1.2: 1. When the length L of the cylindrical portion 2a is slightly increased in this way, it is possible to relieve the twisting load applied to the bowl-shaped portion 2b.

  On the outer surface of the cylindrical portion 2a, a plurality of strip-like protrusions 2c (projections) extend in the axial direction at a predetermined interval. The width of the protrusion 2c is 1.7 to 2.3 mm, preferably 1.9 to 2.1 mm. The height is 0.6 to 1.1 mm, preferably 0.8 to 0.9 mm. The number is 28 to 32, preferably about 30. The protrusion 2c makes it possible to form a portion in contact with the socket 3 described later and a portion having a predetermined interval. The protrusion 2c may have a semicircular cross section (see FIG. 3) or a substantially triangular or elliptical shape.

  On the front and rear surfaces of the flange portion 2b, there are a plurality of strip-shaped protrusions (projections) 2c... Extending radially from the vicinity of the center of the flange portion so as to be continuous with the protrusions 2c of the tubular portion 2a. As it is formed and outwards, its width increases. The ridge 2c of the hook-shaped portion 2b has substantially the same shape as that of the cylindrical portion 2a. However, at the outer edge of the hook-shaped portion 2b, the width of the ridge 2c is 3.0 to 3.5 mm, preferably 3. It has reached 2 to 3.4 mm. The height is 1 to 2 mm, preferably 1.3 to 1.7 mm.

  In addition, you may arrange | position so that the edge parts of the protrusion 2c, 2c of the cylindrical part 2a and the collar-shaped part 2b may become alternate, without making the protrusion 2c continue from the cylindrical part 2a. In this embodiment, although it is formed radially, a plurality of circular ridges that gradually increase in radius from the center to the outside may be provided, or the ridge 2c of the bowl-shaped portion 2b may be provided as a cylinder. The shape may be different from the shape of the protrusion 2c. Further, a plurality of ring-shaped protrusions may be provided on the outer periphery of the cylindrical portion 2a.

  The protrusion 2c is preferably housed in the socket 3 in a state in which the protrusion 2c is elastically contacted so as not to lose elasticity to receive the reaction force of the conduit T. Initially, the tip of the protrusion 2c and the inner surface of the socket are The protrusion 2c may be elastically deformed only when a reaction force by the conduit T is applied in a state of contact.

  The socket 3 has small-diameter portions 3b and 3b for accommodating the cylindrical portions 2a and 2a of the elastic member 2, and the small-diameter portions 2b from the small-diameter portions 3b and 3b through the inner walls 3c and 3c (steps). A large-diameter portion 3d is formed for storing the. An attachment portion 3a (see FIG. 1) is formed at a portion corresponding to the outer periphery of the intermediate portion between the small-diameter portion 3b and the large-diameter portion 3d at the front end, and serves as a joint portion with the mating member. The counterpart member is a stay or a holder formed on the shift lever and the transmission. Further, the inner periphery of the large diameter portion 3d is a portion where the tip portion of the rib 2d (see FIG. 2) elastically contacts. Further, the step portion 3c of the large diameter portion 3d abuts the tip of the projection 2c.

  Next, the state of the elastic member 2 inside the support device A when the AT cable 10 (see FIG. 2) is actually incorporated into the vehicle body will be described with reference to FIG. When a reaction force due to the conduit T is applied to the support device A as indicated by a two-dot chain line in FIG. 3, a force is applied to the casing cap 1 so that the casing cap 1 is directed in the same direction as the end of the conduit T. That is, the force is such that the right end of the casing cap 1 is pushed up and the left end is pushed down, and the casing cap 1 is rotated in the direction of arrow R. At that time, the tubular portion 2a on the right side of the elastic member is pushed up by the casing cap 1 so that the upper portion of the tubular portion 2a strongly contacts the inner surface of the small diameter portion 3b of the socket. On the other hand, the lower part of the left cylindrical part 2a strongly contacts the inner surface of the small diameter part 3b of the socket. At this time, the protrusion 2c formed on the surface of the cylindrical portion elastically supports the force, thereby preventing the elastic member 2 from being excessively displaced.

Further, it is preferable that the small diameter portion 3 b and the stepped portion 3 c at the rear end portion of the socket 3 be a separate part washer 3 g that can be detached from the socket 3. Then, the elastic member 2 can be inserted into the socket 3 whose rear end is open, and then the washer 3g can be crimped and fixed in a state where the elastic member 2 is pressed somewhat in the axial direction.
Further, as shown in FIG. 7, the socket 3 may be structured to be divided into front and rear like a plate 4a and a holding plate 4b. Then, the elastic member 2 can be sandwiched and fixed between the separated plate 4a and pressing plate 4b.

  Further, in the bowl-shaped portion 2b, the upper portion of the left surface strongly abuts on the socket step 3c. On the other hand, the lower part of the right surface strongly contacts the socket step 3c. At this time, the protrusion 2c formed on the surface of the bowl-shaped portion elastically supports the force, thereby preventing the elastic member 2 from undergoing elastic deformation. As described above, the force to rotate the casing cap 1 in the R direction can be supported from the upper, lower, left, and right directions, so that the reaction force at the end of the conduit T can be efficiently supported. Further, since the four portions that support the forces in the four directions are located at a distance r or L from the center of rotation of the casing cap 1 in the R direction, the moment of rotation of the casing cap can be stably supported. it can. As described above, when the length L of the cylindrical portion 2a is long, the reaction force of the conduit T is supported more than the flange-shaped portion 2b so that the reaction force from the conduit T does not easily reach the flange-shaped portion 2b. It may be.

Next, the effects of the support device of the present invention will be described with reference to examples and comparative examples.
[Example 1]
The supporting device A shown in FIG. 1 was adopted as an example. The outer diameter of the thin cylindrical portion 2a of the elastic member 2 is 16 mm at the tip of the ridge 2c, 14 mm at the base of the ridge 2c, and the distance between the front end of the front cylindrical portion 2a and the rear end of the rear cylindrical portion 2a. Is 24 mm, the outer diameter of the flanged portion 2 b of the elastic member 2 is 24 mm, the distance between the front end and the rear end of the flanged portion 2 b is 13 mm between the tips of the protrusions 2 c, and 10 mm between the roots of the protrusions 2 c. Twelve strips 2c are formed. The material of the elastic member 2 was ethylene / propylene / diene copolymer synthetic rubber (EPDM) and had a hardness of 50 °.
[Comparative Example 1]
The terminal support device 110 shown in FIG. 9a was attached to the AT cable. The thickness W of the portion of the anti-vibration rubber 113 that is in contact with the flange 112 was 4 mm. However, the outer diameter D was 25 mm and the inner diameter d was 12 mm.

[Comparative Example 2]
The terminal support device 120 shown in FIG. 9b was attached to the AT cable. The outer diameters of the dampers 124 and 125 were 37 mm, the inner diameter was 16 mm, the thickness was 3.5 mm, the material was EPDM, and the rubber hardness was Hs50. The holding plate was tightened by 1.3 mm from the natural thickness of the dampers 124 and 125.

  FIG. 5 shows the relationship between displacement and operation load when the conduit T is attached to the support device in a straight state (angle α is 0 °) and when the angle α (see FIG. 2) is attached at an angle of 2 °. It is a graph to show. 5a and 5b show the support device A of Example 1 and the support device 120 of Comparative Example 2, respectively. The vertical axis of each graph is the operation load (kgf), and the horizontal axis is the displacement (mm). The solid line in the figure indicates the spring characteristic when the angle α is 2 °, and the dotted line indicates the spring characteristic (constant) when the angle α is 0 ° (see FIG. 4).

  As shown in FIGS. 5a and 5b, in Example 1, the relationship between the load and the displacement is constant even when the angle of the conduit T changes. On the other hand, in the comparative example 2, when the angle α is 2 °, the displacement is small even if the operation load is large due to the twisting, that is, the spring constant is large. Vibration performance is low. This is because the initial displacement of the damper is caused by the twisting.

  Note that the static spring characteristic here refers to a load value (N) when a predetermined displacement is applied to the damper. On the other hand, the dynamic spring characteristic indicates a load value / vibration displacement (N / mm) when a predetermined vibration displacement is applied in a state where a predetermined initial displacement is applied to the damper. The test method for the static spring characteristics and dynamic spring characteristics conforms to JIS K 6394. The “dynamic magnification” means a ratio (kd / ks) between the dynamic spring constant (kd) and the static spring constant (ks), and is also called “dynamic magnification”. Table 1 shows the static spring constants ks and dynamic magnification of Example 1, Comparative Example 1, and Comparative Example 2, respectively.

  In FIG. 6, the result of having measured the noise by the vibration of AT cable 10 and the conventional AT cable 100 from the shift lever side is shown. Two kinds of different types of vehicles are used for the measurement results, which are an actual vehicle 1 and an actual vehicle 2, respectively. FIG. 6A shows the measurement result of noise when the actual vehicle 1 is used, and FIG. 6B shows the measurement result of noise when the actual vehicle 2 is used. The horizontal axis of the graph indicates the noise frequency (Hz), and the vertical axis indicates the noise level (dB). The unit of dB is Pa / N (rms). The solid line shows the case of the AT cable 10 in which the support device A of Example 1 is provided on both sides, and the dotted line uses the support device 110 of Comparative Example 1 on the transmission side and the support device 120 of Comparative Example 2 on the shift lever side. The case of the existing AT cable 100 is shown. In addition, arrows d1 and d2 in the figure indicate noise differences between the case where the AT cable 10 is used and the case where the AT cable 100 is used.

  Vibration from the transmission side via the inner cable and the shift lever deteriorates the acoustic environment in the vehicle, for example, by vibrating the dashboard of the vehicle. However, as shown in FIG. 6, when the AT cable 10 is used, an effect of reducing noise of about 18 dB as d1 and about 22 dB as d2 is recognized. Thus, the acoustic environment in the vehicle could be improved and the soundproofing effect could be improved.

  Furthermore, the supporting device A of the first embodiment can be used on both the transmission side and the shift lever side, and in this case, the elastic member can be used as a common component, so that the cost is low.
