Description

Technical Field

[0001] The invention relates to a pedal assembly structure for a vehicle. Background Art

[0002] Japanese Patent Application Laid-Open No. 2011-063197 discloses a technique related to a so-called organ-type accelerator pedal that is provided on a floor in a vehicle cabin and is provided so as to be rotatable with a rear end portion in the vehicle front-rear direction as a fulcrum.

[0003] In Japanese Patent Application Laid-Open No. 2011-063197, a control box is provided at the front end of an accelerator pedal (hereinafter referred to as "pedal") in the vehicle front-rear direction and at the lower side in the vehicle up-down direction. A coupler is mounted on the front surface of the control box, and a wire harness is connected (hereinafter referred to as "connected") to the coupler, thereby connecting the wire harness to the control box.

[0004] That is, in Japanese Patent Laid-Open No. 2011-063197, the wire harness is connected to the coupler from the front side of the control box provided at the front end side of the pedal in the vehicle front and rear direction. The pedal is provided at the front end in the vehicle front and rear direction in the vehicle interior, so when the wire harness is connected from the front side further in the vehicle front and rear direction than the pedal, the connection operation of the wire harness is difficult. Summary of the invention

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a vehicle pedal assembly structure capable of improving the workability when assembling the pedal to the floor side.

[0006] The first embodiment of the present invention provides a pedal assembly structure for a vehicle comprising: a pedal arranged at the front portion of a vehicle interior, having a pedal pad supported and to which a pedal force is applied in a manner that allows rotation around an axis arranged along the vehicle width direction; a wiring harness connected to the pedal and having a relaxed excess length portion on the front side of the pedal in the vehicle front-rear direction; and a guide member that guides the wiring harness in a manner that the wiring harness is routed on the outside of the pedal pad in a plan view.

[0007] In the first embodiment of the present invention, a pedal assembly structure for a vehicle is provided with a pedal, a wiring harness, and a guide member, wherein the pedal is provided at the front portion of the vehicle interior. A pedal pad to which a pedal force is applied is provided on the pedal, and the pedal pad is supported in a manner that allows rotation around an axis provided along the vehicle width direction. The wiring harness is connected to the pedal, and a slack excess length portion is provided on the front side of the pedal in the vehicle front-rear direction. In addition, the guide member guides the wiring harness in a manner that the wiring harness is routed outside the pedal pad in a plan view.

[0008] For example, when assembling the pedal to the floor, the pedal is fixed to the floor with the harness connected (attached) to the pedal. At this time, if the tension of the harness is high, the margin of the harness when assembling the pedal becomes small, so the position of the pedal is restricted, and the workability is poor accordingly. Therefore, in the present invention, considering the workability when assembling the pedal, a slack excess length portion is provided in the harness.

[0009] On the other hand, as a comparative example, for example, when the wiring harness is located inside the pedal pad in a plan view (that is, the wiring harness overlaps the pedal pad in a plan view), the wiring harness may enter the lower side of the pedal, in which case the wiring harness may be broken due to the pedal pad being stepped on.

[0010] Therefore, as described above, when the wire harness has an extra length, the extra length may enter the lower side of the pedal when the pedal is assembled to the floor side. Therefore, for example, when the pedal is assembled to the floor side, it is necessary to avoid the extra length so as to prevent the extra length from entering the lower side of the pedal, which is not easy to work.

[0011] In contrast, in the present invention, the wire harness including the excess length is guided by the guide member so as to be routed outside the pedal pad in a plan view. As a result, the excess length of the wire harness is prevented from entering the lower side of the pedal. Therefore, in the present invention, when assembling the pedal to the floor side, it is not necessary to avoid the excess length in order to prevent the excess length from entering the lower side of the pedal, thereby improving workability.

[0012] It should be noted that the term "pedal" includes not only the accelerator pedal but also the brake pedal, the clutch pedal, etc. In addition, "connection" includes not only the electrical connection but also the mechanical connection. Moreover, as mentioned above, the "excess length" is required when the pedal is assembled to the floor side. Therefore, after the pedal is assembled to the floor side, there is a case where the excess length remains in a slack state, but there is also a case where the slack of the excess length disappears depending on the wiring of the harness.

[0013] A vehicle pedal assembly structure according to a second aspect of the present invention is the vehicle pedal assembly structure according to the first aspect, wherein the guide member is set so that the excess length portion is formed on a front side of the pedal pad in the vehicle front-rear direction.

[0014] In the vehicle pedal assembly structure of the second aspect of the present invention, the guide member sets the excess length of the wire harness to the front side of the pedal pad in the vehicle front-rear direction.

[0015] The vehicle pedal assembly structure of the third scheme of the present invention is based on the vehicle pedal assembly structure of the first or second scheme, and the guide member is constructed to include: a clamping member, which is installed on a bolt to hold the wiring harness along the vehicle width direction, and the bolt is arranged on a front panel at the front end portion inside the vehicle compartment to divide the vehicle interior and the exterior of the vehicle compartment; and a stop member, which abuts against the clamping member to limit the rotation of the clamping member.

[0016] In the third aspect of the present invention, the guide member is configured to include a clamping member and a stopper member. A dash panel is provided at the front end of the vehicle interior to partition the interior and exterior of the vehicle interior, and a bolt is provided on the dash panel. The clamping member is mounted on the bolt, and the wire harness is held in the vehicle width direction by the clamping member.

[0017] Generally, the clamping member is configured to be mounted on a bolt provided on the dash panel along the axial direction of the bolt and locked to the male threaded portion, so that the clamping member can rotate relative to the bolt.

[0018] Therefore, in the present invention, a stopper member is further included as a guide member. The stopper member abuts against the clamping member to restrict the rotation of the clamping member, and the wiring state of the wire harness along the vehicle width direction is maintained. As a result, the wire harness can be guided in a manner that the wire harness is routed outside the pedal pad in the pedal width direction when viewed from above.

[0019] The vehicle pedal assembly structure of the fourth scheme of the present invention is based on the vehicle pedal assembly structure of any one of the first to third schemes, and the pedal is configured to also include a main body that supports the pedal pad in a rotatable manner and is provided with a connector component connected to the wiring harness, and the guide component includes a retaining component, which is arranged on the connector component side of the wiring harness to maintain the shape of the wiring harness in such a way that the turning portion for changing the wiring path in the excess length portion is located on the outside of the pedal pad in the pedal width direction and on the front side of the pedal pad in the vehicle front-rear direction when viewed from above.

[0020] In the pedal assembly structure for a vehicle of the fourth scheme of the present invention, the pedal is configured to further include a main body portion that supports the pedal pad in a rotatable manner, and a connector component connected to the wire harness is provided on the main body portion. In addition, a retaining component is included as a guide component. The retaining component is provided on the connector component side of the wire harness, and the shape of the wire harness is maintained in such a manner that the turning portion that changes the wiring path in the excess length portion becomes the outside of the pedal pad in the pedal width direction and the front side of the pedal pad in the vehicle front-rear direction when viewed from above. Therefore, in the present invention, the wire harness can be guided in such a manner that the wire harness is routed on the outside of the pedal pad in the pedal width direction when viewed from above.

[0021] As described above, the vehicle pedal assembly structure according to the first aspect of the present invention has an excellent effect of being able to improve the workability when assembling the pedal to the floor side.

[0022] The vehicle pedal assembly structure according to the second aspect of the present invention has an excellent effect of preventing the excess length of the wire harness from entering the lower side of the pedal pad by arranging the excess length of the wire harness on the front side of the pedal pad in the vehicle front-rear direction.

[0023] The vehicle pedal assembly structure according to the third aspect of the present invention has an excellent effect that the wire harness can be maintained in a state where it is routed in the vehicle width direction by the clamping member and the stopper member.

[0024] The vehicle pedal assembly structure according to the fourth aspect of the present invention has an excellent effect that the shape of the wire harness can be held by the holding member so that the wire harness can be routed outside the pedal pad. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the arrow FR appropriately shown in the following figures indicates the front side in the front-rear direction of the vehicle, and the arrow UP indicates the upper side in the up-down direction of the vehicle. In addition, the arrow RH indicates the right side in the width direction of the vehicle. Hereinafter, when only the front-rear, up-down, and left-right directions are used for description, unless otherwise specified, the front-rear direction of the vehicle, the up-down direction of the vehicle, and the left-right direction of the vehicle (the width direction of the vehicle) are indicated.

[0034] <First Embodiment>

[0035] (Structure of pedal assembly structure for vehicle)

[0036] First, the structure of the vehicle pedal assembly structure according to the first embodiment will be described.

[0037] like Figure 1 As shown, an organ-type accelerator pedal (hereinafter referred to as an "organ-type pedal") 12 to which the pedal assembly structure for a vehicle of the present embodiment is applied is provided on the lower inner side of an instrument panel (not shown) on the driver's seat side provided on the left side of the vehicle 10. That is, the vehicle 10 is a so-called left-hand drive vehicle. Of course, the vehicle 10 may also be a right-hand drive vehicle.

[0038] The accordion pedal 12 is provided above the carpet 14 and includes a pedal pad 16 that the rider steps on with his / her soles (including soles of the rider's feet when wearing shoes) and a base member (main body) 18 that rotatably supports the pedal pad 16 .

[0039] The pedal pad 16 is formed of a metal such as aluminum alloy or stainless steel, and has a substantially rectangular plate shape with the longitudinal direction of the vehicle front-rear direction in a plan view. The pedal pad 16 is formed so that the surface 16A is concave-convex, and the position of the sole of the foot does not deviate relative to the surface 16A of the pedal pad 16 when the pedal pad 16 is stepped on.

[0040] On the other hand, the base member 18 is constructed to include a main body portion 20 which is arranged on the lower side of the pedal pad 16 in a plan view and has a generally rectangular shape with the vehicle front-rear direction as its length direction, a left flange portion 24 which is provided on the left side in the vehicle width direction across the main body portion 20, and a right flange portion 25 which is provided on the right side.

[0041] The left flange portion 24 extends outward in the vehicle width direction from the lower portion of the main body portion 20 and is mounted on the floor 22 side. In addition, the left flange portion 24 is provided with a fastening hole 26, and the left flange portion 24 is fastened to the floor 22 (fastening portion 52) by a bolt (not shown) inserted into the fastening hole 26. Thus, the base member 18 is fixed to the floor 22.

[0042] On the other hand, the right flange portion 25 extends from the upper wall portion 20A of the main body portion 20 , and a connector member 34 described later is arranged on the lower side of the right flange portion 25 .

[0043] Here, Figure 4 1 is a side view showing an accordion pedal 12 to which the pedal assembly structure for a vehicle of the second embodiment is applied, and although it is not relevant in this embodiment, a hard pipe 60 described later is provided. As shown in the figure, a shaft portion 28 is provided on the rear end portion 20B side of the main body portion 20 along the vehicle width direction.

[0044] The shaft portion 28 is supported rotatably (rotatably) relative to the main body portion 20, and the rear end portion 16B of the pedal pad 16 is fixed to the shaft portion 28. In other words, the pedal pad 16 can rotate relative to the main body portion 20 (in the direction of arrow A) around the shaft portion 28 including the rear end portion 16B of the pedal pad 16 and with the front end portion 16C of the pedal pad 16 as a free end.

[0045] The pedal pad 16 is provided with a hole 21 (see FIG. 1 ) formed on the back surface 16D side of the pedal pad 16 so as to allow access to the upper wall 20A of the main body 20. Figure 1 ) is inserted into the pressing member 30. A spring member (not shown) is provided in the main body 20, and the front end of the pressing member 30 abuts against the spring member.

[0046] Therefore, when the pedal pad 16 is pressed (when the pedal pad 16 is stepped on by the sole of the foot), the spring member is compressed and deformed by the pressing member 30, and elastic energy is accumulated. Then, when the pressing force on the pedal pad 16 is released (when the sole of the foot is removed), the spring member is restored and the pedal pad 16 returns to its original position (initial state).

[0047] It should be noted that a locking portion (not shown) is provided on the pressing member 30, and a locked portion (not shown) to be locked by the locking portion is formed on the main body 20. The locking portion is locked to the locked portion, and when the spring member is restored, the pressing member 30 is prevented from falling off relative to the main body 20. In other words, the pedal pad 16 maintains a predetermined angle as an initial state when not stepped on by the sole of the foot.

[0048] In addition, in the present embodiment, the structure in which the pressing member 30 is provided on the back surface 16D side of the pedal pad 16 is described, but it is sufficient as long as elastic energy is accumulated in the spring member by pressing the pedal pad 16. Therefore, the pressing member 30 may also be provided on the main body 20 side. In this case, the pressing member 30 moves in the direction of compressing and deforming the spring member by pressing the pedal pad 16.

[0049] Here, when the pedal pad 16 rotates, the shaft 28 to which the pedal pad 16 is fixed rotates together with the pedal pad 16. At this time, although not shown in the figure, the sensor unit detects the rotation amount of the shaft 28 and sends an electrical signal to the engine control unit via the wire harness 32. Through the electrical signal, the opening of the throttle valve of the engine is adjusted according to the rotation amount of the shaft 28. Of course, the opening of the throttle valve can also be mechanically adjusted via the wire harness 32.

[0050] On the other hand, Figure 1 , Figure 2 As shown, a connector member 34 connected to a sensor unit (not shown) is provided on the right side wall portion 20C (on the side of the tunnel portion 56 described later) of the main body portion 20 constituting a part of the base member 18 of the accordion pedal 12. One end portion 32A of the wire harness 32 is connected to the connector member 34, and the other end portion of the wire harness 32 is connected to the engine control unit side, although not shown.

[0051] The engine control unit is disposed in a power unit room provided at the front of the vehicle, for example, and the power unit room and the vehicle interior 36 are partitioned by a dash panel 38. Therefore, a clamping member 40 for holding (retaining) the wire harness 32 is mounted on the dash panel 38 as a part of a guide member 39, and the wire harness 32 is held by the clamping member 40.

[0052] Therefore, the wire harness 32 connected to the connector member 34 provided on the base member 18 of the accordion-type pedal 12 disposed on the vehicle interior 36 side extends from the accordion-type pedal 12 toward the vehicle front side and is routed along the surface side of the dash panel 38. It should be noted that a muffler 42 made of nonwoven fabric having a sound absorbing effect is laid as a sound absorbing and insulating member on the vehicle interior 36 side of the dash panel 38. Therefore, strictly speaking, the wire harness 32 is routed along the surface of the muffler 42.

[0053] Here, a welding bolt 44 is provided on the dash panel 38, and a clamping member 40 is mounted on the welding bolt 44. The clamping member 40 is configured to include a plate-shaped base 46 that abuts against the muffler 42, a mounting portion 48 that is integrally provided with the base 46 and mounted on the welding bolt 44, and a holding portion 50 that is integrally provided with the base 46 and holds (holds) the wire harness 32.

[0054] The mounting portion 48 is formed with, for example, an insertion hole through which the male threaded portion of the welding bolt 44 can be inserted, and a plurality of claws extend from the inner edge of the insertion hole toward the center of the insertion hole. In addition, the claws can be locked to the male threaded portion formed on the welding bolt 44. When the welding bolt 44 is inserted into the insertion hole of the mounting portion 48, the plurality of claws are locked to the male threaded portion of the welding bolt 44, thereby mounting the mounting portion 48 to the welding bolt 44. On the other hand, since the holding portion 50 holds the wire harness 32, the wire harness 32 is routed along the surface side of the front panel 38 via the clamping member 40.

[0055] When assembling the organ pedal 12, first, one end portion 32A of the harness 32 is connected to the connector member 34 of the organ pedal 12. Next, the base member 18 of the organ pedal 12 is fastened to the floor 22 side. However, when assembling the organ pedal 12, the operator enters the vehicle interior 36 side with only the upper body from the outside of the vehicle to perform the above-mentioned series of operations.

[0056] At this time, for example, when the tension of the harness 32 is high, the margin during assembly of the organ pedal 12 becomes small, so the position of the organ pedal 12 is restricted, and the workability is correspondingly poor. Therefore, in this embodiment, the excess length portion 54 that obtains the slack portion 54A is provided in the harness 32 so that the operator can easily assemble.

[0057] On the other hand, in the dash panel 38, as a portion for obtaining a flat seat surface for mounting the clamping member 40, in the present embodiment, a welding bolt 44 is provided on the front side and the upper side of the accordion pedal 12. The mounting portion 48 of the clamping member 40 is mounted on the welding bolt 44. That is, the excess length portion 54 is provided between the clamping member 40 and the connector member 34.

[0058] Here, a tunnel portion 56 is provided protruding upward at the center portion in the vehicle width direction of the floor panel 22, and the connector member 34 connected to the one end portion 32A of the wire harness 32 is provided on the tunnel portion 56 side of the accordion pedal 12. Therefore, the wire harness 32 gripped by the gripping portion 50 of the clamping member 40 is guided to the side wall portion 56A side of the tunnel portion 56.

[0059] That is, the orientation of the clamping member 40 is set so that the wire harness 32 is routed along the vehicle width direction through the gripping portion 50. When the wire harness 32 reaches the side wall portion 56A of the tunnel portion 56, the wire harness 32 is routed along the vehicle front-rear direction. In this way, by routing the wire harness 32 so as to bypass the lower side of the pedal pad 16, the slack amount of the slack portion 54A formed on the front side of the accordion pedal 12 can be reduced.

[0060] As described above, the orientation of the clamping member 40 is set so that the wire harness 32 is routed along the vehicle width direction through the gripping portion 50. Figure 3B As shown, in the present embodiment, as another part of the guide member 39, a silencer (stop member) 58 as a guide member is further provided on the lower side of the clamping member 40 in which a direction is set so that the wiring harness 32 is routed along the width direction of the vehicle through the holding portion 50, so as to abut against the clamping member 40.

[0061] That is, the silencer 58 is formed by increasing the thickness of the silencer 42 below the clamping member 40, and the silencer 58 is brought into contact with the clamping member 40. Of course, the silencer 58 may be provided separately from the silencer 42.

[0062] (Function and effect of pedal assembly structure for vehicle)

[0063] Next, the operation and effects of the vehicle pedal assembly structure according to the present embodiment will be described.

[0064] like Figure 1 , Figure 2 As shown, in this embodiment, the wire harness 32 is connected to the organ pedal 12, and a surplus length portion 54 having a slack portion 54A is provided on the front side of the organ pedal 12. On the other hand, the guide member 39 guides the wire harness 32 so that the wire harness 32 is routed outside the organ pedal 12 in the pedal width direction in a plan view.

[0065] As described above, when the organ pedal 12 is assembled to the floor 22, the organ pedal 12 is fixed to the floor 22 with the harness 32 connected to the organ pedal 12. Therefore, in the present embodiment, in consideration of the workability during assembly of the organ pedal 12, the excess length portion 54 is provided in the harness 32 to obtain the slack portion 54A.

[0066] Thus, in this embodiment, by providing the excess length portion 54, the organ pedal 12 connected with the wiring harness 32 can be assembled toward the floor 22 while ensuring a margin for the wiring harness 32 when assembling the organ pedal 12, thereby improving the workability during assembly of the organ pedal 12.

[0067] On the other hand, as a comparative example, Figure 6 As shown in FIG. 1 , when the excess length 100A of the wire harness 100 is located inside the pedal pad 102 in the pedal width direction when viewed from above (that is, the wire harness 100 overlaps the pedal pad 102 when viewed from above), the wire harness 100 may enter the lower side of the accordion pedal 104. In this case, the wire harness 100 may be broken due to the pedal pad 102 being stepped on.

[0068] In contrast, in this embodiment, if Figure 2 As shown, the wire harness 32 is routed along the vehicle width direction by the guide member 39 including the clamp member 40 and the muffler 58. Thus, in the present embodiment, the wire harness 32 is routed outside the pedal pad 16 in a plan view.

[0069] As a result, in the present embodiment, it is possible to prevent the harness 32 from entering the lower side of the organ pedal 12. Therefore, in the present embodiment, it is possible to prevent the harness 32 from being disconnected due to the pedal pad 16 being stepped on.

[0070] In addition, in the present embodiment, since the entry of the wire harness 32 to the lower side of the organ pedal 12 is suppressed, when the organ pedal 12 is assembled to the floor 22 side, there is no need to avoid the wire harness 32 in a manner to avoid the entry of the wire harness 32 to the lower side of the organ pedal 12, thereby improving workability.

[0071] In addition, in the present embodiment, the wire harness 32 is routed along the vehicle width direction by the clamping member 40, and is routed along the vehicle front-rear direction after reaching the side wall portion 56A of the tunnel portion 56 of the floor 22. Since the connector member 34 to which the one end portion 32A of the wire harness 32 is connected is provided at the right side wall portion 20C of the main body portion 20 of the accordion pedal 12, the wire harness 32 can be routed along the side wall portion 56A of the tunnel portion 56 in the vehicle front-rear direction.

[0072] That is, in the present embodiment, the wire harness 32 can be guided so as to be routed outside the pedal pad 16 in a plan view. In this way, by routing the wire harness 32 so as to bypass the lower side of the pedal pad 16, the slack amount of the slack portion 54A formed on the front side of the accordion pedal 12 can be reduced.

[0073] In this embodiment, a muffler 58 is provided on the lower side of the clamping member 40, and the muffler 58 abuts against the clamping member 40. Since the mounting portion 48 of the clamping member 40 locks the claw portion relative to the male thread portion of the welding bolt 44, if an external force (for example, dead weight) exceeding the friction force generated between the male thread portion of the welding bolt 44 and the claw portion acts on the clamping member 40, the Figure 3A As shown, the clamping member 40 is rotated relative to the weld bolt 44 .

[0074] Therefore, in this embodiment, if Figure 3B As shown, the muffler 58 is provided in the direction in which the weight of the wire harness 32 acts, and the muffler 58 abuts against the clamp member 40 to restrict the rotation of the clamp member 40. That is, in this embodiment, the wire harness 32 can be maintained in a state of being routed in the vehicle width direction.

[0075] Thus, in the present embodiment, the muffler 58 (muffler 42) is used to restrict the rotation of the clamping member 40. Since the muffler 42 is laid on the dash panel 38, by making use of the muffler 42, there is no need to separately provide a member for restricting the rotation of the clamping member 40. However, as long as the rotation of the clamping member 40 can be restricted by abutting against the clamping member 40, other members other than the muffler 58 may be used.

[0076] <Second Embodiment>

[0077] Next, the structure of the pedal assembly structure for a vehicle of the second embodiment is described. It should be noted that the basic structure of the pedal assembly structure for a vehicle in this embodiment is substantially the same as the structure of the pedal assembly structure for a vehicle in the first embodiment. Therefore, in this embodiment, the contents different from the first embodiment are described.

[0078] In this embodiment, if Figure 4 As shown in FIG. 1 , the hard tube (holding member) 60 is externally inserted on the one end portion 32A (connector member 34 ) side of the wire harness 32 . Thus, the wire harness 32 can be routed along the shape of the hard tube 60 .

[0079] One end portion 32A of the wire harness 32 is routed along the vehicle front-rear direction together with the hard tube 60 in a state where the hard tube 60 is externally inserted. The length of the hard tube 60 is set so that the front end 60A of the hard tube 60 protrudes from the front end of the pedal pad 16 in a plan view. On the other hand, in the excess length portion 54 of the wire harness 32, the routing path 62 for routing the wire harness 32 is changed by the turning portions 62A and 62B.

[0080] Here, a turning portion 62A is provided near the front end 60A of the hard tube 60, and the wiring path 62 is set so as to face the rear side of the vehicle through the turning portion 62A and then face the front side of the vehicle (the clamping member 40 side) through the turning portion 62B. Moreover, the turning portions 62A and 62B are respectively set so as to face the front side of the accordion pedal 12. Thus, in the present embodiment, the shape of the wire harness 32 can be maintained so as to face the front side of the accordion pedal 12 in a plan view.

[0081] In this way, by using the hard tube 60, the turning parts 62A and 62B of the wiring path 62 are respectively set so as to be on the front side of the accordion pedal 12. In the present embodiment, the excess length part 54 of the wire harness 32 is set so as to be arranged on the front side of the accordion pedal 12. Therefore, in the present embodiment, it is possible to prevent the excess length part 54 of the wire harness 32 from entering the lower side of the accordion pedal 12.

[0082] It should be noted that in this embodiment, the hard tube 60 is used, but as long as the wire harness 32 can be routed along the front-rear direction of the vehicle, it is not limited to the hard tube 60. For example, if the connector cover 34A, the tape winding portion 64 wound with a tape such as a polyvinyl chloride tape, etc. can hold the wire harness 32, the same effect as the hard tube 60 can be obtained. In addition, this embodiment can also be applied together with the first embodiment.

[0083] In addition, in the present embodiment, the hard tube 60 is externally inserted on the one end 32A side of the wire harness 32, but it is sufficient to set it so that the front end 60A of the hard tube 60 protrudes from the front end of the pedal pad 16 in a plan view. Therefore, depending on the arrangement location of the connector member 34, it is not necessarily necessary to externally insert the hard tube 60 on the one end 32 side of the wire harness 32.

[0084] For example, as a variation of this embodiment, Figure 5 As shown, when the connector member 34 is arranged on the rear side of the accordion pedal 12 in the vehicle front-rear direction, if the length of the hard tube 60 is set in a manner so that the front end 60A of the hard tube 60 protrudes from the front end of the pedal pad 16 in a plan view, the length of the hard tube 60 will become longer.

[0085] Therefore, a holder 66 is provided on the right side wall portion 20C of the main body portion 20 of the accordion pedal 12, and the hard tube 60 is fixed by holding the hard tube 60 with the holder 66. In this case, the one end portion 32A side of the wire harness 32 may also be exposed. Thus, the hard tube 60 can be set to the minimum necessary length.

[0086] Furthermore, the pedal pad 16 according to the vehicle floor structure including the accordion pedal of the present embodiment is described as the pedal pad 16 of the accordion pedal 12 , but is not limited thereto and may be applied to a pedal pad of an accordion brake pedal or the like.

[0087] Furthermore, in the present embodiment, the organ pedal 12 includes the pedal pad 16 and the base member 18 that rotatably supports the pedal pad 16 . However, the base member 18 is not necessarily required as long as the pedal pad 16 is rotatably supported.

[0088] The vehicle floor structure including the accordion pedal of the present embodiment is not limited to vehicles that run by the driving force of an engine, but can also be applied to electric vehicles that run by the driving force of an electric motor.

[0089] As mentioned above, although one embodiment of the present invention has been described, the present invention is not limited to the above, and it is needless to say that the present invention can be implemented with various modifications other than the above within the scope not departing from the gist of the present invention.
