Title: Vehicle pedal installation structure

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application is based on and claims priority under 35 USC 119 from Japanese Patent Application No. 2021-001639 filed on Jan. 7, 2021, the disclosure of which is incorporated by reference herein. 
     BACKGROUND 
     Technical Field 
     The present disclosure relates to a pedal installation structure for a vehicle. 
     Related Art 
     Japanese Patent Application Laid-Open (JP-A) No. 2011-063197 discloses a technique relating to a so-called organ-type accelerator pedal that is set above a floor panel in a vehicle cabin interior and is provided so as to be able to pivot with the vehicle longitudinal direction rear end portion thereof being the fulcrum. 
     In JP-A No. 2011-063197, a control box is provided at the vehicle longitudinal direction front end portion and the vehicle vertical direction lower side of the accelerator pedal (hereinafter simply called “pedal”). A coupler is mounted to the front surface of the control box, and a harness is joined (hereinafter called “connected”) to the coupler, and the harness is thereby connected to the control box. 
     Namely, in JP-A No. 2011-063197, the harness is connected to the coupler from the vehicle longitudinal direction front side of the control box that is provided at the vehicle longitudinal direction front end portion side of the pedal. Because the pedal is provided at the vehicle longitudinal direction front end portion of the vehicle cabin interior, the work involved in connecting the harness is difficult in a case in which the harness is connected from further toward the vehicle longitudinal direction front side than the pedal. 
     SUMMARY 
     The present disclosure provides a pedal installation structure for a vehicle that can improve the workability at the time of assembling a pedal to a floor panel side. 
     A first aspect of the present disclosure is a pedal installation structure for a vehicle the pedal installation structure including: a pedal provided at a front portion of a vehicle cabin interior, the pedal having a pedal pad to which stepping force is applied and that is supported so as to be able to pivot around a shaft portion provided along a vehicle transverse direction; a harness connected to the pedal, the harness having, at a vehicle longitudinal direction front side of the pedal, a surplus length portion by which slack is obtained; and a guiding member that guides the harness such that the harness is routed at an outer side of the pedal pad, as seen in a plan view. 
     The pedal installation structure for a vehicle of the first aspect of the present disclosure has the pedal, the harness and the guiding member. The pedal is provided at the front portion of the vehicle cabin interior. The pedal has the pedal pad to which stepping force is applied. The pedal pad is supported so as to be able to pivot around a shaft portion that is provided along the vehicle transverse direction. The harness is connected to the pedal, and has, at the vehicle longitudinal direction front side of the pedal, a surplus length portion by which slack is obtained. Further, the guiding member guides the harness such that the harness is routed at the outer side of the pedal pad as seen in a plan view. 
     For example, at the time when the pedal is assembled to the floor panel side, the pedal is fixed to the floor panel side in a state in which the harness is connected (joined) to the pedal. At this time, in a case in which the tension of the harness is high, there is little slack of the harness at the time of installing the pedal, and therefore, the position of the pedal is restricted, and the workability deteriorates by that much. Accordingly, the surplus length portion by which slack is obtained is provided at the harness in consideration of the workability at the time of installing the pedal. 
     On the other hand, as a comparative example, in a case in which the harness overlaps the inner side of the pedal pad as seen in a plan view, i.e., a case in which the harness overlaps the pedal pad as seen in a plan view, there is the possibility that the harness will enter-in beneath the pedal, and, in this case, there is also the possibility that the harness will break due to the pedal pad being depressed. 
     Accordingly, as described above, in a case in which a surplus length portion is provided at the harness, there is the possibility that the surplus length portion will enter-in beneath the pedal at the time of assembling the pedal to the floor panel side. Therefore, for example, at the time of assembling the pedal to the floor panel side, the surplus length portion must be avoided in order for it to not enter-in beneath the pedal, and, with regard to this point, the workability is poor. 
     In contrast, in the present disclosure, the harness that has the surplus length portion is guided by the guiding member so as to be routed at the outer side of the pedal pad as seen in a plan view. Due thereto, entering-in of the surplus length portion of the harness beneath the pedal is suppressed. Accordingly, in the present disclosure, at the time of assembling the pedal to the floor panel side, there is no need to avoid the surplus length portion in order for the surplus length portion to not enter-in beneath the pedal, and the workability may improve. 
     Note that “pedal” includes, other than the accelerator pedal, the brake pedal, the clutch pedal and the like. Further, “connect” includes mechanical connection in addition to electrical connection. Moreover, as described above, the “surplus length portion” is needed at the time of assembling the pedal to the floor panel side. Therefore, after the pedal is assembled to the floor panel side, there are cases in which the surplus length portion remains in a state in which there is slack thereat, and there are also cases in which the slack of the surplus length portion is eliminated by the routing of the harness. 
     In a second aspect of the present disclosure, in the first aspect, the guiding member may be set such that the surplus length portion is disposed at a vehicle longitudinal direction front side of the pedal pad. 
     In the pedal installation structure for a vehicle of the second aspect of the present disclosure, the surplus length portion of the harness is disposed at the vehicle longitudinal direction front side of the pedal pad by the guiding member. Due thereto, in the present disclosure, entering-in of the surplus length portion of the harness beneath the pedal may be suppressed. 
     In a third aspect of the present disclosure, in the first or second aspect, the guiding member may include: a clamp member that, at a front end portion of the vehicle cabin interior, is mounted to a bolt provided at a dash panel separating the vehicle cabin interior and a vehicle cabin exterior, and that holds the harness along the vehicle transverse direction; and a stopper member that abuts the clamp member and restricts rotation of the clamp member. 
     In the pedal installation structure for a vehicle of the third aspect of the present disclosure, the guiding member is structured to include a clamp member and a stopper member. The dash panel that separates the vehicle cabin interior and the vehicle cabin exterior is provided at the front end portion of the vehicle cabin interior, and a bolt is provided at the dash panel. The clamp member is mounted to the bolt, and the harness is held along the vehicle transverse direction by the clamp member. 
     Generally, the clamp member is structured so as to be mounted to a bolt, which is provided at the dash panel, along the axial direction of the bolt, and so as to be anchored on the male screw portion. Therefore, the clamp member can rotate with respect to the bolt. 
     Accordingly, the present disclosure further includes the stopper member as the guiding member. Due to the stopper member abutting the clamp member and restricting rotation of the clamp member, the state in which the harness is routed along the vehicle transverse direction is maintained. As a result, the harness may be guided so as to be routed at the pedal width direction outer side of the pedal pad as seen in a plan view. 
     In a fourth aspect of the present disclosure, in any one of the first through third aspects, the pedal may include a main body portion, the main body portion pivotably supporting the pedal pad and having a connector member to which the harness is connected; and the guiding member may include a retaining member that is provided at the connector member side of the harness and that retains a shape of the harness such that a bent portion, which changes a routing path at the surplus length portion, is at a pedal width direction outer side of the pedal pad and at a vehicle longitudinal direction front side of the pedal pad, as seen in a plan view. 
     In the pedal installation structure for a vehicle of the fourth aspect of the present disclosure, the pedal is structured so as to further include a main body portion that pivotably supports the pedal pad. The connector member to which the harness is connected is provided at the main body portion. Further, the maintaining member is included as the guiding member. The maintaining member is provided at the connector member side of the harness, and maintains the shape of the harness such that a bent portion, which changes the routing path at the surplus length portion, is at the pedal width direction outer side of the pedal pad and is at the vehicle longitudinal direction front side of the pedal pad as seen in a plan view. Due thereto, in the present disclosure, the harness may be guided so as to be routed at the pedal width direction outer side of the pedal pad as seen in a plan view. 
     As described above, the pedal installation structure for a vehicle of the first aspect of the present disclosure may improve the workability at the time when a pedal is assembled to a floor panel side. 
     The pedal installation structure for a vehicle of the second aspect of the present disclosure, due to the surplus length portion of the harness being disposed at the vehicle longitudinal direction front side of the pedal pad, entering-in of the surplus length portion beneath the pedal pad may be suppressed. 
     In the pedal installation structure for a vehicle of the third aspect of the present disclosure, the state in which the harness is routed along the vehicle transverse direction may be maintained by the clamp member and the stopper member. 
     In the pedal installation structure for a vehicle of the fourth aspect of the present disclosure, the shape of the harness may be maintained by the maintaining member, and the harness may be routed at the outer side of the pedal pad.

     DETAILED DESCRIPTION 
     A pedal, to which pedal installation structures for a vehicle relating to present embodiments are applied, is described hereinafter with reference to the drawings. Note that arrow FR that is illustrated appropriately in the following drawings indicates the front side in the vehicle longitudinal direction, and arrow UP indicates the upper side in the vehicle vertical direction. Further, arrow RH indicates the right side in the vehicle transverse direction. Hereinafter, when description is given by using merely longitudinal, vertical, and left-right directions, they refer to the longitudinal of the vehicle longitudinal direction, the vertical of the vehicle vertical direction, and the left and right of the vehicle left-right direction (the vehicle transverse direction), unless otherwise indicated. 
     &lt;First Embodiment&gt; 
     First, the structure of the pedal installation structure for a vehicle relating to a first embodiment is described. 
     As illustrated in  FIG. 1 , an organ-type accelerator pedal (hereinafter called “organ-type pedal”)  12 , to which the pedal installation structure for a vehicle relating to the present embodiment is applied, is provided at the deep side of the lower portion of the portion of the instrument panel (not illustrated) that is at the driver&#39;s seat side that is provided at the left side of a vehicle  10 . Namely, the vehicle  10  is a so-called left-hand drive vehicle. The vehicle  10  may, of course, be a right-hand drive vehicle. 
     The organ-type pedal  12  is provided at the upper side of a floor carpet  14 , and is structured to include a pedal pad  16  that the driver depresses with his/her foot (including the sole when the driver is wearing shoes), and a base member (main body portion)  18  that pivotably supports the pedal pad  16 . 
     The pedal pad  16  is formed of a metal such as, for example, an aluminum alloy, stainless steel or the like, and, as seen in a plan view, is formed in a substantially rectangular plate shape whose length direction is the vehicle longitudinal direction. At the pedal pad  16 , an obverse surface  16 A is formed in a recessed and protruded form. The pedal pad  16  is formed such that, in the state in which the pedal pad  16  is depressed, the position of the foot does not become offset from the obverse surface  16 A of the pedal pad  16 . 
     On the other hand, the base member  18  is structured by: a main body portion  20  that, as seen in a plan view, is disposed at the lower side of the pedal pad  16  and is shaped as a substantial rectangle whose length direction is the vehicle longitudinal direction; and a left flange portion  24  provided at the vehicle transverse direction left side and a right flange portion  25  provided at the right side, with respect to the main body portion  20 . 
     The left flange portion  24  projects-out toward the vehicle transverse direction outer side from the lower portion of the main body portion  20 , and is mounted to a floor panel  22  side. Fastening holes  26  are provided in the left flange portion  24 , and the left flange portion  24  is fastened to the floor panel  22  (fastened portions  52 ) via bolts (not illustrated) that are inserted in the fastening holes  26 . Due thereto, the base member  18  is fixed to the floor panel  22 . 
     On the other hand, the right flange portion  25  projects-out from an upper wall portion  20 A of the main body portion  20 . A connector member  34  that is described later is disposed at the lower side of the right flange portion  25 . 
     Here,  FIG. 4  is a side view illustrating the organ-type pedal  12  to which a pedal installation structure for a vehicle relating to a second embodiment is applied. Although unrelated to the present embodiment, a hard tube  60  that is described later is provided. As illustrated in  FIG. 4 , a shaft portion  28  is provided along the vehicle transverse direction at a rear end portion  20 B side of the main body portion  20 . 
     This shaft portion  28  is rotatably (pivotably) supported with respect to the main body portion  20 , and a rear end portion  16 B of the pedal pad  16  is fixed to the shaft portion  28 . Namely, the pedal pad  16  can pivot (the arrow A direction) with respect to the main body portion  20  around the shaft portion  28  including the rear end portion  16 B of the pedal pad  16 , with a front end portion  16 C of the pedal pad  16  being the free end portion. 
     Further, a pushing member  30 , which can be inserted through a hole portion  21  (see  FIG. 1 ), which is formed in the upper wall portion  20 A of the main body portion  20  for example, is provided at a reverse surface  16 D side of the pedal pad  16 . Although not illustrated, a spring member is provided within the main body portion  20 , and the distal end portion of the pushing member  30  abuts the spring member. 
     Therefore, when the pedal pad  16  is pushed (is stepped upon by the foot), the spring member is compressively deformed by the pushing member  30 , and elastic energy accumulates thereat. Then, when the pushing force on the pedal pad  16  is released (when the foot is removed therefrom), the spring member is restored, and the pedal pad  16  returns to its original position (initial state). 
     Note that, although not illustrated, an anchor portion is provided at the pushing member  30 , and an unillustrated anchored-on portion, which the anchor portion anchors on, is formed at the main body portion  20 . Due to the anchor portion anchoring on the anchored-on portion, at the time when the spring member is restored, the pushing member  30  is prevented from coming out of the main body portion  20 . Namely, in the state in which the pedal pad  16  is not being depressed by the foot, the pedal pad  16  is maintained at a predetermined angle as the initial state thereof. 
     Further, although the present embodiment describes a structure in which the pushing member  30  is provided at the reverse surface  16 D side of the pedal pad  16 , it suffices for elastic energy to accumulate at the spring member due to the pedal pad  16  being pushed. Therefore, the pushing member  30  may be provided at the main body portion  20  side. In this case, due to the pushing of the pedal pad  16 , the pushing member  30  moves in the direction of compressively deforming the spring member. 
     Here, when the pedal pad  16  pivots, the shaft portion  28  to which the pedal pad  16  is fixed pivots integrally with the pedal pad  16 . At this time, although not illustrated, a sensor portion senses the amount of pivoting of the shaft portion  28 , and transmits an electric signal to an engine control unit via a wire harness  32 . Due to this electric signal, the degree of opening of the throttle valve of the engine is adjusted in accordance with the amount of pivoting of the shaft portion  28 . Of course, the degree of opening of the throttle valve may be adjusted mechanically via the wire harness  32 . 
     On the other hand, as illustrated in  FIG. 1  and  FIG. 2 , the connector member  34  that is connected to the unillustrated sensor portion is provided at a right side wall portion  20 C (hereinafter called tunnel portion  56  side) of the main body portion  20  that structures a portion of the base member  18  of the organ-type pedal  12 . One end portion  32 A 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 illustrated. 
     The engine control unit is, for example, disposed within the power unit chamber that is provided at the vehicle front portion. The power unit chamber and a vehicle cabin interior  36  are separated by a dash panel  38 . Therefore, a clamp member  40  for grasping (holding) the wire harness  32  is mounted to the dash panel  38  as a portion of a guiding member  39 , and the wire harness  32  is grasped by this clamp member  40 . 
     Accordingly, the wire harness  32 , which is connected to the connector member  34  provided at the base member  18  of the organ-type pedal  12  that is disposed at the vehicle cabin interior  36  side, extends-out from the organ-type pedal  12  toward the vehicle front side, and is routed along the revers surface side of the dash panel  38 . Note that a silencer  42 , which is made of a non-woven fabric and has a sound-absorbing effect as a sound-insulating member, is laid at the vehicle cabin interior  36  side of the dash panel  38 . Therefore, strictly speaking, the wire harness  32  is routed along the obverse surface of the silencer  42 . 
     Here, a weld bolt  44  is provided at the dash panel  38 , and the clamp member  40  is mounted to the weld bolt  44 . The clamp member  40  is structured to include a base portion  46  that is plate-shaped and abuts the silencer  42 , a mounted portion  48  that is provided integrally with the base portion  46  and is mounted to the weld bolt  44 , and a grasping portion  50  that is provided integrally with the base portion  46  and grasps (holds) the wire harness  32 . 
     For example, an insert-through hole, through which the male screw portion of the weld bolt  44  can be inserted, is formed in the mounted portion  48 , and plural claw portions project-out from the inner edge of the insert-through hole toward the center of the insert-through hole. The claw portions can anchor on the male screw portion that is formed at the weld bolt  44 . When the weld bolt  44  is inserted into the insert-through hole of the mounted portion  48 , the plural claw portions anchor on the male screw portion of the weld bolt  44 , and, due thereto, the mounted portion  48  is mounted to the weld bolt  44 . On the other hand, because the grasping portion  50  grasps the wire harness  32 , the wire harness  32  can be routed along the obverse surface side of the dash panel  38  via the clamp member  40 . 
     By the way, at the time of installing the organ-type pedal  12 , first, the one end portion  32 A of the wire harness  32  is connected to the connector member  34  of the organ-type pedal  12 . Next, the base member  18  of the organ-type pedal  12  is fastened to the floor panel  22  side. At the time of installing the organ-type pedal  12 , the worker sticks only the upper half of his/her body into the vehicle cabin interior  36  side from the vehicle outer side, and carries out the above-described series of operations. 
     At this time, for example, in a case in which the tension of the wire harness  32  is high, there is little slack (play) at the time of installing the organ-type pedal  12 , and therefore, the position of the organ-type pedal  12  is restricted, and the workability deteriorates by that much. Thus, in the present embodiment, a surplus length portion  54  by which a slack portion  54 A is obtained is provided at the wire harness  32  in order to facilitate installation for the worker. 
     On the other hand, at the dash panel  38 , the weld bolt  44  is provided at the front side and the upper side of the organ-type pedal  12  in the present embodiment, as a region at which a flat seat surface for mounting the clamp member  40  is obtained. The mounted portion  48  of the clamp member  40  is mounted to this weld bolt  44 . Namely, the surplus length portion  54  is provided between the clamp member  40  and the connector member  34 . 
     Here, the tunnel portion  56  is provided at the vehicle transverse direction central portion of the floor panel  22  so as to project-out toward the upper side. The connector member  34 , to which the one end portion  32 A of the wire harness  32  is connected, is provided at the tunnel portion  56  side of the organ-type pedal  12 . Therefore, the wire harness  32 , which is grasped by the grasping portion  50  of the clamp member  40 , is guided toward a side wall portion  56 A side of the tunnel portion  56 . 
     Namely, the orientation of the clamp member  40  is set such that the wire harness  32  is routed along the vehicle transverse direction by the grasping portion  50 . Then, when the wire harness  32  reaches the side wall portion  56 A of the tunnel portion  56 , the wire harness  32  is routed along the vehicle longitudinal direction. In this way, by routing the wire harness  32  so as not to pass the lower side of the pedal pad  16 , the amount of slack of the slack portion  54 A that is formed at the front side of the organ-type pedal  12  can be reduced. 
     As described above, the orientation of the clamp member  40  is set such that the wire harness  32  is routed along the vehicle transverse direction by the grasping portion  50 . As illustrated in  FIG. 3B , in the present embodiment, silencers (stopper members)  58  that serve as a guiding member are further provided as another portion of the guiding member  39 , so as to abut the clamp member  40  at the lower side of the clamp member  40  whose orientation is set such that the wire harness  32  is routed along the vehicle transverse direction by the grasping portion  50 . 
     Namely, at the lower side of the clamp member  40 , the plate thickness of the silencer  42  is made to be thick, and the silencers  58  are formed. The silencers  58  are made to abut the clamp member  40 . Of course, a silencer may be provided separately from the silencer  42 . 
     Operation of the pedal installation structure for a vehicle relating to the present embodiment are described next. 
     As illustrated in  FIG. 1  and  FIG. 2 , in the present embodiment, the wire harness  32  is connected to the organ-type pedal  12 , and the surplus length portion  54  that has the slack portion  54 A is provided at the front side of the organ-type pedal  12 . On the other hand, the guiding member  39  guides the wire harness  32  such that, as seen in a plan view, the wire harness  32  is routed at the outer side in the pedal width direction of the organ-type pedal  12 . 
     As described above, at the time of assembling the organ-type pedal  12  to the floor panel  22  side, the organ-type pedal  12  is fixed to the floor panel  22  side in the state in which the wire harness  32  is connected to the organ-type pedal  12 . Therefore, in the present embodiment, the surplus length portion  54  by which the slack portion  54 A is obtained is provided at the wire harness  32  in consideration of the workability at the time of installing the organ-type pedal  12 . 
     In this way, in the present embodiment, by providing the surplus length portion  54 , the organ-type pedal  12  to which the wire harness  32  is connected can be assembled to the floor panel  22  side upon ensuring slack of the wire harness  32  at the time of installing the organ-type pedal  12 . Therefore, an improvement in workability at the time of installing the organ-type pedal  12  may be devised. 
     On the other hand, as a comparative example, as illustrated in  FIG. 6 , in a case in which a surplus length portion  100 A of a wire harness  100  is at the inner side in the pedal width direction of a pedal pad  102  as seen in a plan view, i.e., in a case in which the wire harness  100  overlaps the pedal pad  102  as seen in a plan view, there is the possibility that the wire harness  100  will enter-in beneath an organ-type pedal  104 . In this case, there is also the possibility that the wire harness  100  will break due to the pedal pad  102  being depressed. 
     In contrast, in the present embodiment, as illustrated in  FIG. 2 , the wire harness  32  is routed along the vehicle transverse direction by the guiding member  39  that includes the clamp member  40  and the silencers  58 . Due thereto, in the present embodiment, the wire harness  32  is routed at the outer side of the pedal pad  16  as seen in a plan view. 
     As a result, in the present embodiment, it can be made such that the wire harness  32  does not enter-in beneath the organ-type pedal  12 . Accordingly, in the present embodiment, breakage of the wire harness  32  that arises due to the pedal pad  16  being depressed may be prevented. 
     Further, in the present embodiment, because entering-in of the wire harness  32  beneath the organ-type pedal  12  is suppressed, at the time when the organ-type pedal  12  is assembled to the floor panel  22  side, there is no need to avoid the wire harness  32  in order for the wire harness  32  to not enter-in beneath the organ-type pedal  12 , and the workability improves. 
     Further, in the present embodiment, the wire harness  32  is routed along the vehicle transverse direction by the clamp member  40 , and, when the wire harness  32  reaches the side wall portion  56 A of the tunnel portion  56  of the floor panel  22 , the wire harness  32  is routed along the vehicle longitudinal direction. Because the connector member  34 , to which the one end portion  32 A of the wire harness  32  is connected, is provided at the right side wall portion  20 C of the main body portion  20  of the organ-type pedal  12 , the wire harness  32  can be routed in the vehicle longitudinal direction along the side wall portion  56 A of the tunnel portion  56 . 
     Namely, in the present embodiment, the wire harness  32  can be guided so as to be routed at the outer side of the pedal pad  16  as seen in a plan view. In this way, by routing the wire harness  32  so as not to pass the lower side of the pedal pad  16 , the amount of slack of the slack portion  54 A that is formed at the front side of the organ-type pedal  12  can be reduced. 
     By the way, in the present embodiment, the silencers  58  are provided at the lower side of the clamp member  40 , and abut the clamp member  40 . At the mounted portion  48  of the clamp member  40 , the claw portions anchor on the male screw portion of the weld bolt  44 . Therefore, when external force (e.g., self-weight), which exceeds the frictional force arising between the male screw portion of the weld bolt  44  and the claw portions, acts on the clamp member  40 , as illustrated in  FIG. 3A , the clamp member  40  rotates with respect to the weld bolt  44 . 
     Therefore, in the present embodiment, as illustrated in  FIG. 3B , by providing the silencers  58  in the direction in which the self-weight due to the wire harness  32  is applied, and causing the silencers  58  to abut the clamp member  40 , rotation of the clamp member  40  is restricted. Namely, in the present embodiment, the state in which the wire harness  32  is routed along the vehicle transverse direction may be maintained. 
     In this way, in the present embodiment, rotation of the clamp member  40  is restricted by using the silencers  58  (the silencer  42 ). Because the silencer  42  is laid at the dash panel  38 , by utilizing the silencer  42 , there is no need to separately provide a member for restricting rotation of the clamp member  40 . However, because it suffices to be able to restrict rotation of the clamp member  40  by abutting the clamp member  40 , another member other than the silencers  58  may, of course, be used. 
     &lt;Second Embodiment&gt; 
     The structure of a pedal installation structure for a vehicle relating to a second embodiment is described next. The basic structure of the pedal installation structure for a vehicle in the present embodiment is substantially the same as the structure of the pedal installation structure for a vehicle of the first embodiment. Therefore, in the present embodiment, contents which differ from the first embodiment are described. 
     In the present embodiment, as illustrated in  FIG. 4 , the hard tube (holding member)  60  is placed on the exterior of the one end portion  32 A (the connector member  34 ) side of the wire harness  32 . Due thereto, the wire harness  32  can be routed along the shape of the hard tube  60 . 
     The one end portion  32 A side of the wire harness  32  is, together with the hard tube  60 , routed along the vehicle longitudinal direction in the state in which the hard tube  60  is placed on the exterior of the one end portion  32 A. The length of the hard tube  60  is set such that, as seen in a plan view, a distal end  60 A of the hard tube  60  does not project-out from the distal end of the pedal pad  16 . On the other hand, at the surplus length portion  54  of the wire harness  32 , a routing path  62  along which the wire harness  32  is routed is changed by bent portions  62 A,  62 B. 
     Here, the bent portion  62 A is provided in a vicinity of the distal end  60 A of the hard tube  60 , and, after the routing path  62  heads toward the vehicle rear side due to the bent portion  62 A, the routing path  62  heads toward the vehicle front side (the clamp member  40  side) due to the bent portion  62 B. Moreover, the bent portions  62 A,  62 B are respectively set so as to be at the front side of the organ-type pedal  12 . Due thereto, in the present embodiment, the shape of the wire harness  32  can be maintained such that the wire harness  32  is at the front side of the organ-type pedal  12  as seen in a plan view. 
     By respectively setting the bent portions  62 A,  62 B of the routing path  62  so as to be at the front side of the organ-type pedal  12  by the hard tube  60  in this way, in the present embodiment, the surplus length portion  54  of the wire harness  32  is disposed at the front side of the organ-type pedal  12 . Due thereto, in the present embodiment, it can be made such that the surplus length portion  54  of the wire harness  32  does not enter-in beneath the organ-type pedal  12 . 
     Note that, although the hard tube  60  is used in the present embodiment, because it suffices to be able to route the wire harness  32  along the vehicle longitudinal direction, the present disclosure is not limited to the hard tube  60 . Effects that are similar to those of the hard tube  60  may be obtained provided that there is provided a member that can hold the wire harness  32  such as, for example, a connector cover  34 A, a wound tape portion  64  at which a tape such as a vinyl tape or the like is wound, or the like. Further, the present embodiment can be applied together with the first embodiment. 
     Further, in the present embodiment, the hard tube  60  is placed on the exterior of the one end portion  32 A side of the wire harness  32 . However, it suffices for the distal end  60 A of the hard tube  60  to project-out from the distal end of the pedal pad  16  as seen in a plan view. Therefore, depending on the place at which the connector member  34  is disposed, it is not absolutely necessary to place the hard tube  60  at the exterior of the one end portion  32 A side of the wire harness  32 . 
     For example, as illustrated in  FIG. 5  as a modified example of the present embodiment, in a case in which the connector member  34  is provided at the vehicle longitudinal direction rear portion side of the organ-type pedal  12 , if the length of the hard tube  60  is set such that the distal end  60 A thereof projects-out from the distal end of the pedal pad  16  as seen in a plan view, the length of the hard tube  60  becomes long. 
     Therefore, the hard tube  60  is fixed by providing a holder  66  at the right side wall portion  20 C of the main body portion  20  of the organ-type pedal  12 , and holding the hard tube  60  by this holder  66 . In this case, the one end portion  32 A side of the wire harness  32  may be exposed. Due thereto, the hard tube  60  can be set to the minimum length needed. 
     Further, the pedal pad  16 , which relates to a vehicle floor structure having the organ-type pedal relating to the present embodiment, is described as the pedal pad  16  of the organ-type pedal  12 . However, the present disclosure is not limited to this, and may be applied to the pedal pad of an organ-type brake pedal or the like. 
     Moreover, in the present embodiment, the organ-type pedal  12  is structured to include the pedal pad  16  and the base member  18  that supports the pedal pad  16  pivotably. However, because it suffices for the pedal pad  16  to be pivotably supported, the base member  18  is not absolutely necessary. 
     The vehicle floor structure that has the organ-type pedal relating to the present embodiment is not limited to a vehicle that runs by the driving force of an engine, and may be applied to an electric vehicle at which the vehicle runs by the driving force of a motor. 
     Although embodiments of the present disclosure have been described above, the present disclosure is not limited to the above, and, of course, can be implemented by being modified in various ways other than the above within a scope that does not depart from the gist thereof.
