[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-110936 Summary of the Invention [Problem to be solved by the invention]

[0004] The select cable in Patent Document 1 is routed between the engine compartment and the passenger compartment through a through-hole in the panel that separates the engine compartment and the passenger compartment. However, because the select cable is long, inserting the select cable into the through-hole when assembling it is time-consuming, leaving room for improvement in ease of cable assembly.

[0005] Furthermore, because select cables are generally rigid and cannot be bent sharply, routing them perpendicular to the through-hole can result in the select cable protruding significantly from the through-hole and potentially interfering with other components. This places restrictions on the position of the through-hole and the placement of other components, reducing the degree of freedom in routing the select cable. Meanwhile, by inserting the select cable at an angle to the panel, as in Patent Document 1, the select cable can be prevented from protruding significantly from the through-hole, but the insertion direction of the select cable is restricted, leaving room for improvement in the degree of freedom in routing the cable.

[0006] The present invention has been made in consideration of the problems described above, and aims to improve the assembly ease of wiring components and to increase the degree of freedom when wiring the wiring components. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of the present invention is an operation force transmission structure 100 for a vehicle, which includes a link member 140 that is disposed by passing through a vehicle body panel 30 that separates the inside and outside of a vehicle compartment, a first cable 110 that is connected to the link member 140 and routed inside the vehicle compartment 21, and a second cable 120 that is connected to the link member 140 and routed outside the vehicle compartment 21 separated by the vehicle body panel 30. The operation force transmission structure 100 transmits the operation force from the inside of the vehicle compartment 21 to the second cable 120 via the link member 140, thereby transmitting the operation force from the inside of the vehicle compartment 21 to the outside of the vehicle compartment 21 through the vehicle body panel 30. Therefore, the first cable 110 and the second cable 120 can be routed separately inside and outside the vehicle compartment, respectively, thereby improving the ease of assembly of the first cable 110 and the second cable 120. Furthermore, by dividing the cable into the first cable 110 and the second cable 120, it is possible to prevent the cable from being routed in a curved or bent state, thereby improving the degree of freedom when routing the cable. [Example]

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vehicle operation force transmission structure according to the present invention will now be described with reference to the drawings. FIG. 1 is a diagram showing the configuration of a portion of a vehicle 10 equipped with an operating force transmission structure 100. In the drawings including FIG. 1 and the description, the forward direction of the vehicle is referred to as the front, with the operating force transmission structure mounted on the vehicle as the reference, and the front side is indicated by an arrow "front," and the opposite side is referred to as the rear side. The left side is indicated by an arrow "left," and the opposite side is referred to as the right side. The upper side is indicated by an arrow "up," and the opposite side is referred to as the lower side.

[0012] Vehicle 10 has an engine compartment 11 (outside the passenger compartment) in the front, and a passenger compartment 21 extending from the center to the rear. An engine 13 integrally coupled to an automatic transmission 12 is mounted in engine compartment 11. Meanwhile, a shift lever 22 is provided in passenger compartment 21 for the driver to change the shift position. An operating force generated when the driver operates shift lever 22 is transmitted to automatic transmission 12 via operating force transmission structure 100. More specifically, the generated operating force is transmitted by a first cable 110 (described later) connected to shift lever 22 and routed inside passenger compartment 21, a main body 130 (described later), and a second cable 120 (described later) connected to a switching lever (not shown) of automatic transmission 12 and routed within engine compartment 11. Therefore, when the driver operates the shift lever 22 to change the shift position, the operating force is transmitted to the switching lever of the automatic transmission 12 via the operating force transmission structure 100, and the automatic transmission 12 changes gear.

[0013] FIG. 2 is a diagram for explaining the position where the operating force transmission structure 100 is arranged, and is a vertical cross section taken along line II shown in FIG. 1 and seen from the direction of the arrow. As shown in Fig. 2, the inside and outside of the vehicle interior 21 of the vehicle 10 are separated by a vehicle body panel 30. Here, the vehicle body panel 30 is configured to include a dash panel 31 located at the front of the vehicle interior 21 and a floor panel 32 located below the vehicle interior 21. The dash panel 31 separates the engine compartment 11 and the vehicle interior 21 from the front to the rear. Meanwhile, the floor panel 32 separates the interior of the vehicle interior 21 from the space below the vehicle interior 21 from the top to the bottom.

[0014] 1 and 2 has a floor tunnel portion 33 that protrudes upward at the center in the vehicle width direction (left-right direction) and extends in the front-rear direction. Here, the main body portion 130 of the operating force transmission structure 100 is disposed in a position on the panel surface 34 of the floor tunnel portion 33 close to the dash panel 31 side. Specifically, a through-hole 35 that penetrates the panel surface 34 of the floor tunnel portion 33 in the up-down direction is formed, and the main body portion 130 of the operating force transmission structure 100 is attached to the through-hole 35. Note that the floor tunnel portion 33 constitutes a part of the floor panel 32, and therefore, in the following description, the floor tunnel portion 33 will be referred to as the floor panel 32.

[0015] 1 and 2, the position where the main body 130 of the operating force transmission structure 100 is attached is adjacent to the instrument panel 36 on the upper side and adjacent to the exhaust pipe 37 and propeller shaft 38 on the lower side. The operating force transmission structure 100 of this embodiment can be assembled without interfering with other components even in such a position where other components are close to it.

[0016] (First Example) First, an example of the configuration of the main body 130 of the operating force transmission structure 100 according to the first embodiment will be described with reference to Figures 3 and 4. Figure 3 is a perspective view showing an example of the configuration of the main body 130 of the operating force transmission structure 100. Figure 4 is a cross-sectional view seen from the front, cut along a line passing through the central axis of a swing arm 141 and the central axis of a swing pin 143, which will be described later. The main body 130 includes a link member 140 , a base member 150 , and a grommet member 160 .

[0017] The link member 140 is disposed through the through-hole 35 of the floor panel 32, and transmits the operating force of the shift lever 22 from the first cable 110 to the second cable 120. Specifically, the link member 140 has a swing arm 141 and a swing pin 143.

[0018] The swing arm 141 is swingable around the swing pin 143 and is swingable around a central axis C that is disposed along the horizontal direction of the swing pin 143. The swing arm 141 is a generally rod-shaped member that is long in the vertical direction and is made of, for example, metal. When the main body 130 is attached to the floor panel 32, the swing arm 141 is disposed in a state in which it penetrates the through-hole 35. The swing arm 141 has a first connecting portion 142a at its upper end (one end) for connecting the first cable 110, and a second connecting portion 142b at its lower end (the other end) for connecting the second cable 120. The first connecting portion 142a and the second connecting portion 142b protrude in a direction (here, leftward) perpendicular to the axial direction of the swing arm 141, their central axes are disposed parallel to the central axis C of the swing pin 143, and their tips are formed in a generally spherical shape. Here, the first cable 110 and the second cable 120 connected to the first connecting portion 142a and the second connecting portion 142b are push-pull cables. Each push-pull cable includes a long inner wire and an outer casing, and the inner wire is slidable within the outer casing. In the push-pull cable, the inner wire and the outer casing each have rigidity, and the inner wire can transmit operating force not only when it slides in one direction along the longitudinal direction relative to the outer casing, but also when it slides in the other direction. The inner wire of the first cable 110 is connected to the first connecting portion 142a, and the inner wire of the second cable 120 is connected to the second connecting portion 142b. The first cable 110 corresponds to an example of a first routing member, and the second cable 120 corresponds to an example of a second routing member.

[0019] The swing pin 143 is swingably supported by the base member 150. The swing pin 143 is a generally columnar member elongated in the left-right direction and made of, for example, metal. The swing pin 143 is located between the upper and lower ends of the swing arm 141 and is integrally connected to the swing arm 141 by press-fitting or welding. However, the swing arm 141 and the swing pin 143 may be formed as a single component made of metal or synthetic resin by casting or injection molding. When viewed from the direction in which the central axis C of the swing pin 143 extends, the central axis C, the first connecting portion 142a, and the second connecting portion 142b are aligned. As shown in FIG. 4, the distance from the central axis C of the swing pin 143 to the first connecting portion 142a is defined as L1, and the distance from the central axis C of the swing pin 143 to the second connecting portion 142b is defined as L2. In the link member 140 of this embodiment, the distance L1 is substantially the same as the distance L2. That is, the swing pin 143 is located in the approximate center between the first connecting portion 142a and the second connecting portion 142b of the swing arm 141.

[0020] The base member 150 supports the link member 140 so that it can swing. The base member 150 also functions as an attachment portion when attaching the main body portion 130 to the floor panel 32. The base member 150 is a generally plate-shaped member that is more rigid than the grommet member 160 and is made of, for example, metal. The base member 150 is placed on the exterior side of the floor panel 32 and attached to the floor panel 32 with bolts (not shown). When the main body portion 130 is attached to the floor panel 32, the base member 150 is disposed generally parallel to the panel surface 34 of the floor panel 32. The base member 150 has an insertion hole 151 and a pair of support holes 152. The insertion hole 151 is located approximately in the center of the main body portion 130. When the main body portion 130 is attached to the floor panel 32, the insertion hole 151 is disposed below the through hole 35 of the floor panel 32 so as to face the through hole 35 in the up-down direction, and the swing arm 141 is inserted through the insertion hole 151. The pair of support holes 152 are formed in a pair of hanging portions 153 that extend downward from the opening edge of the insertion hole 151. The pair of support holes 152 pivotally support the swing pin 143 so that it can swing. Note that bushings 154 made of synthetic resin are fitted into the pair of support holes 152 so that the swing pin 143 can swing smoothly. Also, stop pins 155 are attached to both ends of the swing pin 143 to prevent the swing pin 143 from slipping out of the support holes 152.

[0021] The grommet member 160 seals the gap between the floor panel 32 and the main body 130 to prevent dust, water, noise, and the like from entering the interior of the vehicle compartment 21 through the through-hole 35 of the floor panel 32. The grommet member 160 is a member that is more flexible than the base member 150 and is made of, for example, rubber. When the main body 130 is attached to the floor panel 32, the grommet member 160 is positioned so as to overlap the upper side of the base member 150. The grommet member 160 has a boot portion 161 and a protrusion 163. The boot portion 161 is generally cylindrical and tapers downward, and is large enough to accommodate a portion of the swing arm 141 and a portion of the swing pin 143 in its internal space. The boot portion 161 protrudes downward from the center of the grommet member 160 through the insertion hole 151 of the base member 150, and its lower end is fixed at a position between the swing pin 143 and the second connecting portion 142b. The boot portion 161 also has a pair of holes 162 through which the swing pin 143 extends from both the left and right sides. The boot portion 161 seals the inside of the vehicle interior 21 to prevent the intrusion of dust, water, noise, etc. through the insertion hole 151 of the base member 150. The boot portion 161 can bend in accordance with the swing of the swing arm 141. The protrusion 163 protrudes from the upper surface of the grommet member 160 and is arranged in an annular shape so as to surround the swing arm 141 when viewed from above. When the main body 130 is attached to the floor panel 32, the protrusion 163 adheres closely to the underside of the floor panel 32, sealing the inside of the passenger compartment 21 from dust, water, noise, etc., which can enter through the through hole 35 of the floor panel 32.

[0022] Next, a case where the main body 130 of the operating force transmission structure 100 configured as described above is attached to the floor panel 32 will be described. A worker assembling the vehicle 10 inserts the swing arm 141 from below through the through hole 35 of the floor panel 32 and brings the protrusion 163 of the grommet member 160 into close contact with the underside of the floor panel 32. Next, the worker attaches the main body 130 to the floor panel 32 by fastening the base member 150 to the floor panel 32 with fastening members such as bolts. With the main body 130 attached to the floor panel 32, the swing pin 143 is positioned near the through hole 35 of the floor panel 32. Specifically, as shown in FIG. 4 , the swing pin 143 is positioned near the bottom of the through hole 35 of the floor panel 32 so that the distance S between the swing pin 143 and the floor panel 32 in which the through hole 35 is formed is smaller than the distance L1. In addition, the first connecting portion 142a of the swing arm 141 is located inside the vehicle interior 21, and the second connecting portion 142b of the swing arm 141 is located on the opposite side of the floor panel 32 from the inside of the vehicle interior 21, i.e., outside the vehicle interior 21.

[0023] When assembling the first cable 110 and the second cable 120 to the main body 130 attached to the floor panel 32, the first cable 110 and the second cable 120 can be routed individually inside and outside the vehicle interior 21. Specifically, an assembly worker routes the first cable 110 inside the vehicle interior 21 by connecting the inner wire of the first cable 110 to the first connecting portion 142a of the swing arm 141 located inside the vehicle interior 21. Furthermore, the assembly worker routes the second cable 120 outside the vehicle interior 21 by connecting the inner wire of the second cable 120 to the second connecting portion 142b of the swing arm 141 located outside the vehicle interior 21. In this way, the ability to route the cables individually inside and outside the vehicle interior 21 improves the ease of assembling the cables compared to routing a single rigid and non-flexible cable through a through-hole in a vehicle body panel. The assembly worker fixes the outer casings of the first cable 110 and the second cable 120 to the floor panel 32 or the like via brackets (not shown).

[0024] 2, in the operation force transmission structure 100 attached to the floor panel 32, the first cable 110 is routed from the main body 130 toward the rear side parallel to the panel surface 34 of the floor panel 32 and is connected to the shift lever 22. Meanwhile, as shown in FIG. 2, the second cable 120 is routed from the main body 130 toward the front side parallel to the panel surface 34 of the floor panel 32 through the floor tunnel portion 33 and is connected to the shift lever of the automatic transmission 12 in the engine compartment 11. By routing the first cable 110 and the second cable 120 parallel to the panel surface 34 of the floor panel 32 in this way, it is possible to prevent the first cable 110 and the second cable 120 from interfering with other components such as the instrument panel 36, the exhaust pipe 37, and the propeller shaft 38.

[0025] Next, the operation of the operating force transmission structure 100 will be described. Here, it is assumed that the driver operates the shift lever 22, causing the inner wire of the first cable 110 to slide rearward (in the direction of arrow R in FIG. 2) relative to the outer casing. As the inner wire of the first cable 110 slides rearward, the swing arm 141 connected to the inner wire of the first cable 110 swings around the swing pin 143. Specifically, the swing arm 141 swings so that the first connecting portion 142a moves rearward and, conversely, the second connecting portion 142b moves forward. Therefore, the inner wire of the second cable 120 connected to the second connecting portion 142b slides forward (in the direction of arrow F in FIG. 2) relative to the outer casing. When the inner wire of the second cable 120 slides forward, the shift lever of the automatic transmission 12 connected to the inner wire of the second cable 120 moves, and the automatic transmission 12 changes gears.

[0026] On the other hand, when the inner wire of first cable 110 slides forward relative to the outer casing, swing arm 141 swings so that first connecting portion 142a moves forward and second connecting portion 142b moves rearward, causing the inner wire of second cable 120 connected to second connecting portion 142b to slide rearward relative to the outer casing. In this way, the operating force generated by the driver operating shift lever 22 is transmitted to automatic transmission 12 via operating force transmission structure 100.

[0027] As described above, the operating force transmission structure 100 of this embodiment includes the link member 140 that is disposed by inserting through the vehicle body panel 30, the first cable 110 that is connected to the link member 140 and routed inside the vehicle interior 21, and the second cable 120 that is connected to the link member 140 and routed outside the vehicle interior 21. The operating force transmission structure 100 transmits the operating force from the inside of the vehicle interior 21 to the outside of the vehicle interior 21 by transmitting the operating force from the first cable 110 to the second cable 120 via the link member 140.

[0028] According to this embodiment, the cable is divided into a first cable 110 and a second cable 120, and the divided first cable 110 and the divided second cable 120 are each connected to a link member 140 that is inserted through the vehicle body panel 30. Therefore, the first cable 110 and the second cable 120 can be routed separately inside and outside the vehicle interior 21, respectively, improving the ease of assembling the cable. Furthermore, by dividing the cable into the first cable 110 and the second cable 120, it is possible to prevent the cable from being routed in a curved or bent state, thereby improving the degree of freedom when routing the cable.

[0029] Furthermore, according to this embodiment, the swing pin 143, which is the center of the swing arm 141 when it swings, is disposed near the through hole 35, thereby making it possible to reduce the stroke amount of the swing arm 141 near the through hole 35. Since the stroke amount of the swing arm 141 is small, it is not necessary to make the through hole 35 large to avoid interference with the swing arm 141, and therefore the through hole 35 can be made smaller. By making the through hole 35 smaller, it is possible to prevent dust, water, noise, and the like from entering the interior of the vehicle compartment 21 through the through hole 35. Furthermore, by making the through hole 35 smaller, it is possible to also make the grommet member 160, which is used to prevent the entry of dust, water, and noise, smaller.

[0030] Furthermore, according to this embodiment, by routing the first cable 110 and the second cable 120 parallel to the panel surface 34 of the vehicle body panel 30, the cables can be prevented from protruding perpendicularly to the panel surface 34, thereby suppressing interference with other components. This improves the degree of freedom when routing the cables and improves the degree of freedom in the arrangement position of the through holes 35. Note that both the first cable 110 and the second cable 120 are not limited to being routed parallel to the panel surface 34 of the vehicle body panel 30, and either the first cable 110 or the second cable 120 may be routed parallel to the panel surface 34 of the vehicle body panel 30.

[0031] Furthermore, according to this embodiment, the swing pin 143 is disposed outside the passenger compartment 21. Therefore, the boot portion 161 is set to have a long length from its upper end to its lower end so that a portion of the swing pin 143 can be accommodated in the inner space. By increasing the length from the upper end to the lower end of the boot portion 161 in this way, it is possible to distribute the force acting on the boot portion 161 when the boot portion 161 bends in accordance with the swing of the swing arm 141, and it is possible to prevent the boot portion 161 from being damaged.

[0032] In the first embodiment, the case where the locking pins 155 are attached to both ends of the swing pin 143 to prevent the swing pin 143 from slipping out of the support hole 152 of the base member 150 has been described, but this can be modified as appropriate. 5 is a diagram showing an example of another retaining structure for swing pin 143. Base member 150 has abutment stopper 156 on the outer side (left side in this case) of left hanging portion 153, against which the left end of swing pin 143 abuts. Meanwhile, by fitting cap member 157 onto the right end of swing pin 143, a configuration can be achieved in which swing pin 143 does not come out of support hole 152 of base member 150.

[0033] (Second Example) Next, an example of the configuration of the main body 230 of the operating force transmission structure 200 according to the second embodiment will be described with reference to Figs. 6 and 7. Fig. 6 is a perspective view showing an example of the configuration of the main body 230 of the operating force transmission structure 200. Fig. 7 is a cross-sectional view seen from the front, cut through the central axis of the swing arm 141 and the central axis of the swing pin 143. Note that components similar to those in the first embodiment will be given the same reference numerals, and descriptions thereof will be omitted where appropriate.

[0034] The main body 230 has a link member 140, a base member 250, a grommet member 260, and a boot member 270. The grommet member 260 of this embodiment does not have the boot portion 161 integrated therewith, and the main body 230 has the boot member 270 that is separate from the grommet member 260. The base member 250 has an engaged portion 254 that engages with an engaging portion 271 (described later) of the boot member 270. The engaged portion 254 protrudes from the lower surface at a position close to the outer periphery of the base member 250, and is arranged in a ring shape so as to surround the swing arm 141 when viewed from below. The grommet member 260 has an insertion hole 264 that communicates with the insertion hole 151 of the base member 250 .

[0035] The boot member 270 seals the underside of the base member 250 to prevent dust, water, noise, and the like from entering the interior of the vehicle compartment 21 through the insertion hole 151 of the base member 250 and the insertion hole 264 of the grommet member 260. The boot member 270 is a member that is more flexible than the base member 250 and is made of, for example, rubber. The boot member 270 has a generally cylindrical shape that tapers downward and is large enough to accommodate the swing pin 143 in its internal space. An engagement portion 271 is formed along the edge of the opening at the upper end of the boot member 270, and the engagement portion 271 engages with the engaged portion 254 of the base member 250. Meanwhile, the lower end of the boot member 270 is fixed at a position between the swing pin 143 and the second connecting portion 142b. The boot member 270 is capable of bending in accordance with the swing of the swing arm 141.

[0036] As described above, in the operating force transmission structure 200 of this embodiment, the boot member 270 is separate from the grommet member 260, and seals the underside of the base member 250 so as to cover the swing pin 143 from the outside. Therefore, the boot member 270 can further prevent dust, water, noise, and the like from entering the inside of the vehicle interior 21 through the insertion hole 151 of the base member 250.

[0037] (Third Example) Next, an example of the configuration of the main body 330 of the operating force transmission structure 300 according to the third embodiment will be described with reference to Figs. 8 and 9. Fig. 8 is a perspective view showing an example of the configuration of the main body 330 of the operating force transmission structure 300. Fig. 9 is a cross-sectional view taken along the vertical direction passing through the center of the swing pin 341 and viewed from the front. Note that components similar to those in the first and second embodiments are given the same reference numerals, and descriptions thereof will be omitted where appropriate. The main body portion 330 includes a link member 340 , a base member 350 , and a grommet member 360 .

[0038] The link member 340 is disposed through the through-hole 35 of the floor panel 32, and transmits the operating force of the shift lever 22 from the first cable 110 to the second cable 120. Specifically, the link member 340 has a swing pin 341, a first swing arm 342a, and a second swing arm 342b.

[0039] The swing pin 341 is rotatable around a central axis C along the vertical direction, centered on a support portion 351 (described later) of the base member 350. The swing pin 341 is a generally shaft-shaped member that is long along the vertical direction, and is made of, for example, metal. When the main body portion 330 is attached to the floor panel 32, the swing pin 341 is disposed in a state where it penetrates through the through-hole 35.

[0040] The first swing arm 342a and the second swing arm 342b swing integrally with the swing pin 341 around the central axis C of the swing pin 341. The first swing arm 342a and the second swing arm 342b are generally plate-shaped members that are long in the horizontal direction and are made of, for example, metal. When the main body 330 is attached to the floor panel 32, the first swing arm 342a is located inside the vehicle interior 21, and the second swing arm 342b is located outside the vehicle interior 21.

[0041] The base end of the first swing arm 342a is coupled to the upper end of the swing pin 341. Specifically, a spline portion 343 formed on the upper part of the swing pin 341 is inserted into the base end of the first swing arm 342a, thereby integrating the first swing arm 342a with the swing pin 341. A circlip 344 fitted to the tip of the swing pin 341 prevents the first swing arm 342a from slipping out. The first swing arm 342a extends from the base end toward one side in the left-right direction (here, the right side), and has a first connecting portion 142a at its tip for connecting the first cable 110. The first connecting portion 142a protrudes upward in parallel with the axial direction of the swing pin 341.

[0042] The second swing arm 342b has a base end coupled to the lower end of the swing pin 341. Specifically, the base end of the second swing arm 342b is welded to a head 345 formed at the lower end of the swing pin 341, thereby integrating the second swing arm 342b with the swing pin 341. The second swing arm 342b extends from the base end toward the other side in the left-right direction (here, the left side), and has a second connecting portion 142b at its tip for connecting the second cable 120. The second connecting portion 142b protrudes downward in parallel with the axial direction of the swing pin 341. When viewed from the direction in which the central axis C of the swing pin 341 extends, the central axis C, the first connecting portion 142a, and the second connecting portion 142b are positioned on a straight line. 9, if the distance from the central axis C of the swing pin 341 to the first connecting portion 142a is L1 and the distance from the central axis C of the swing pin 341 to the second connecting portion 142b is L2, then in the link member 340 of this embodiment, the distance L1 and the distance L2 are substantially the same.

[0043] The base member 350 supports the link member 340 so that it can swing. The base member 350 also functions as an attachment portion when attaching the main body portion 330 to the floor panel 32. The base member 350 is a substantially plate-shaped member that is more rigid than the grommet member 360 and is made of, for example, metal. When the main body portion 330 is attached to the floor panel 32, the base member 350 is disposed substantially parallel to the panel surface 34 of the floor panel 32. The base member 350 has a cylindrical support portion 351 that is located approximately in the center and extends in the up-down direction. The support portion 351 supports the swing pin 341 within the cylinder so that it can rotate about a central axis C. The support portion 351 is also disposed in a state where it passes through an insertion hole 264 (described later) of the grommet member 360 and a through-hole 35 of the floor panel 32. In order for the support portion 351 to smoothly rotate the swing pin 341, washers 352 are placed on the upper and lower ends of the support portion 351, and a bush 353 made of synthetic resin is fitted between the support portion 351 and the swing pin 341.

[0044] The grommet member 360 seals the gap between the floor panel 32 and the main body 330 to prevent dust, water, noise, and the like from entering the interior of the vehicle compartment 21 through the through-hole 35 of the floor panel 32. When the main body 330 is attached to the floor panel 32, the grommet member 360 is disposed so as to overlap the upper side of the base member 350. The grommet member 360 has a protrusion 163 and an insertion hole 264. When the main body 330 is attached to the floor panel 32, the protrusion 163 comes into close contact with the underside of the floor panel 32, thereby sealing the gap to prevent dust, water, noise, and the like from entering the interior of the vehicle compartment 21 through the through-hole 35 of the floor panel 32.

[0045] The main body 330 of the operating force transmission structure 300 configured as described above can be attached to the floor panel 32, and the first cable 110 and the second cable 120 can be assembled to the main body 330 attached to the floor panel 32 in the same manner as in the first embodiment. Here, it is assumed that the driver operates the shift lever 22, causing the inner wire of the first cable 110 to slide rearward relative to the outer casing. As the inner wire of the first cable 110 slides rearward, the first swing arm 342a connected to the inner wire of the first cable 110 swings around the swing pin 341. Specifically, the first connecting portion 142a of the first swing arm 342a swings rearward, and conversely, the second connecting portion 142b of the second swing arm 342b swings forward. Therefore, the inner wire of the second cable 120 connected to the second connecting portion 142b slides forward relative to the outer casing. As the inner wire of the second cable 120 slides forward, the shift lever of the automatic transmission 12 connected to the inner wire of the second cable 120 moves, causing the automatic transmission 12 to change gears.

[0046] As described above, in the operating force transmission structure 300 of this embodiment, the swing pin 341, which is inserted through the through hole 35 of the floor panel 32, rotates about the central axis C, causing the first swing arm 342a and the second swing arm 342b to swing. Therefore, because the swing pin 341 does not move within the through hole 35, there is no need to make the through hole 35 larger to avoid interference, and the through hole 35 can be made smaller. By making the through hole 35 smaller, it is possible to prevent dust, water, noise, and the like from entering the interior of the vehicle compartment 21 through the through hole 35.

[0047] In the third embodiment, when viewed from the direction in which the central axis C of the swing pin 341 extends, the central axis C, the first connecting portion 142a, and the second connecting portion 142b are positioned on a straight line, but this can be changed as appropriate. For example, the second swing arm 342b1 may extend from the base end toward one side in the front-rear direction (here, the front side) as shown by the two-dot chain line in Fig. 8. In this case, when viewed from the direction in which the central axis C of the swing pin 341 extends, the angle formed by the direction in which the first swing arm 342a extends from the base end and the direction in which the second swing arm 342b1 extends from the base end is approximately 90 degrees.

[0048] Furthermore, the second swing arm 342b2 may extend toward one side in the left-right direction (here, the right side) as shown by the two-dot chain line in Fig. 8. In this case, when viewed along the central axis C of the swing pin 341, the first swing arm 342a and the second swing arm 342b2 are positioned overlapping each other, and the angle formed between the direction in which the first swing arm 342a extends from the base end and the direction in which the second swing arm 342b2 extends from the base end is approximately 0 degrees. In this case, since the swing directions of the first swing arm 342a and the second swing arm 342b2 are always the same, when the driver operates the shift lever 22 to slide the inner wire of the first cable 110 rearward, the inner wire of the second cable 120 also slides rearward. Therefore, such a structure in which the first swing arm 342a and the second swing arm 342b2 overlap each other can be applied as is to existing vehicles in which an operating force is transmitted by a single cable.

[0049] (Variation) In the first to third embodiments described above, the distance L1 from the central axis C of the swing pins 143, 341 to the first connecting portion 142a and the distance L2 from the central axis C of the swing pins 143, 341 to the second connecting portion 142b are substantially the same. However, the distances L1 and L2 can be configured to be different. By making the distances L1 and L2 different in this way, the stroke amount transmitted to the second cable 120 is different from the stroke amount of the first cable 110. For example, when the distance L1 is longer than the distance L2, the driver can reduce the operating force required to slide the first cable 110 relative to the stroke amount or force required for the second cable 120, compared to when the distances L1 and L2 are substantially the same. On the other hand, when distance L2 is longer than distance L1, compared to when distance L1 and distance L2 are approximately the same, the stroke amount when the driver slides first cable 110 can be made shorter relative to the stroke amount or force required for second cable 120. Therefore, the stroke amount or operating force of first cable 110 when operated by the driver can be adjusted relative to the stroke amount or force required for second cable 120.

[0050] The above describes the embodiments and modifications of the present invention, but the present invention is not limited to the above-described embodiments and modifications, and modifications are possible within the scope of the present invention, and the configurations of the embodiments and modifications can be combined or substituted as appropriate.

[0051] The operation force transmission structures 100 to 300 of the above-described embodiments have been described as being used to transmit the operation force of the shift lever 22 to the automatic transmission 12, but the present invention is not limited to this and can be used to transmit the operation force of various operation levers to the outside of the passenger compartment 21. The operation force transmission structures 100 to 300 may also be used, for example, as a structure for unlocking a door for accessing an engine compartment, a motor compartment, a trunk compartment, a fuel filler opening, a charging port, etc. Specifically, the operation force transmission structures 100 to 300 can be used to transmit the operation force of an operation lever provided inside the passenger compartment 21 to a locking mechanism of the door via the operation force transmission structures 100 to 300.

[0052] In the above-described embodiment, a case where a push-pull cable is used as the routing member is described, but this is not limited to this. The routing member may be, for example, a cable that can transmit operating force in only one direction along the length of the cable. Furthermore, the routing member is not limited to a cable and may be, for example, a rigid rod member. In the above-described embodiment, the operating force transmission structures 100 to 300 are described as being arranged in the floor tunnel section 33, but this is not limited to this case, and they may also be arranged in other vehicle body panels 30 such as the floor panel 32 or dash panel 31 other than the floor tunnel section 33.

[0053] In the above-described embodiments, the bracket for fixing the outer casing of the first cable 110 or the second cable 120 may be integrally formed with the base member 150, 250, 350, or a separate bracket may be provided and connected to the base member 150, 250, 350 so as to be integral therewith. In the above-described embodiments, the base members 150, 250, 350 may be integrally formed with the body panel 30. [Explanation of symbols]
