That is, at the retracted position where the seat cushion 1a of the driver's seat 1 moves to the rear side of the vehicle body, as shown in FIG. 7, the front link 73 and the central link 77 are tilted backward, and the rear link 75 Since the connecting shaft 76 provided at the rear end of the seat cushion is positioned below, the seat surface of the seat cushion 1a is held in a state of being largely inclined backward.

  In the above configuration, when an operation for moving the driver's seat 1 to the front side of the vehicle is performed by the front / rear adjustment switch, the drive motor 85 of the tilt angle adjustment mechanism 3 is adjusted based on the preset drive characteristics. A control signal for driving the rotation is output from a control means (not shown), and the normal driving force of the driving motor 85 is transmitted through the gear mechanism 86, the screw shaft 84, the connecting pin 83, the driving lever 81 and the driving shaft 80 to the central link. 77, the central link 77 shifts from the rearward tilt state to the standing state shown in FIG. Then, as the central link 77 shifts to the standing state, the driving force is transmitted to the rear link 75 via the connecting link 79, and the front end portion of the rear link 75 is pulled to the front side of the vehicle. The connecting shaft 76 provided at the rear end portion of the rear link 75 is raised, and the rear end portion of the seat cushion 1a is driven to be pushed up accordingly.

  Further, since the front link 73 shifts from the rearward tilted state to the upright state in conjunction with the swinging displacement of the rear link 75, the front end portion of the seat cushion 1a is moved forward while being pushed up accordingly. When driven, the seat cushion 1a is displaced from the lower position to the upper position shown in FIG. Furthermore, the backward movement angle of the seat surface according to the upward movement of the seat cushion 1a is set by setting the upward movement amount of the rear end part larger than the upward movement amount of the front end part of the seat cushion 1a. It changes so that it may become small gradually, and it is constituted so that it may approach a horizontal state. Further, the tilt angle of the seat back 1b changes in conjunction with the tilt displacement of the seat cushion 1a, and is displaced so as to approach the vertical state.

  On the other hand, when an operation for moving the driver's seat 1 to the rear side of the vehicle body is performed by the front / rear adjustment switch, the drive motor 85 of the tilt angle adjusting mechanism 3 is driven in reverse based on a preset drive characteristic. A control signal is output from the control means, and the forward drive force of the drive motor 85 is transmitted to the central link 77 via the gear mechanism 86, the screw shaft 84, the connecting pin 83, the drive lever 81 and the drive shaft 80. As a result, the seat cushion 1a is displaced from the upper position to the lower position shown in FIG. 7, and as the seat cushion 1a moves downward, the rearward tilt angle of the seat surface gradually changes, and the seat The back 1b is configured to be largely inclined backward.

  When the driver sitting on the driver's seat 1 changes to a person with a different height, the driver's seat height, arm length, foot length, etc. change in proportion to the height. Thus, the operability of the driver's eye point seated on the driver's seat 1 and the operation pedal such as the accelerator pedal 4 also changes. Therefore, the driver who newly sits on the driver's seat 1 can grip the steering handle 92 in an appropriate state while maintaining the comfortable posture, and the pedal on the stepping portion 4 a of the movable pedal member 17 constituting the accelerator pedal 4. The front / rear position adjusting mechanism 2 and the tilt angle adjustment so that the lever ball portion of the operation foot can be brought into contact with each other in an appropriate state and the eye point is aligned with the appropriate line L so that the front view can be properly secured. An attempt is made to adjust the front and rear position of the driver seat 1 by operating the mechanism 3.

  Since the driver seat 1 may be seated by drivers having various heights, from a person with a height of 150 cm or less to a person with a height of 190 cm or more, these persons can sit on the driver seat 1 in an easy posture. Therefore, it is necessary to configure so that the driving operation can be performed properly. For example, assuming that the height of the average height person M who is most likely to sit on the driver's seat 1 is 170 cm and statistically analyzing the comfort posture of the average height person M, the following data is obtained. was gotten.

  The comfort posture of the occupant seated on the driver's seat 1 is a seating posture that can maintain the seated state for a long period of time and is suitable for handle operation, pedal operation, and the like. Specifically, as shown in FIG. 13, the ankle angle θ1 of the pedal operation foot is about 85 ° to 95 °, the knee angle θ2 is about 115 ° to 135 °, and the upper body and the thigh from the hip to the shoulder. And the bending angle θ4 is about 95 °. In the case of the average height person M, the appropriate angle of the rhino angle θ3, which is the angle formed by the thighs with respect to the horizontal line, is a value obtained by adding about 1.5 ° to the inclination angle of the seat cushion 1a. This has been confirmed by ergonomic experiments. Further, the elbow angle θ5 at which the steering handle 92 can be properly operated is about 100 ° to 130 °, and the side angle θ6 is about 20 ° to 45 °.

  Therefore, for example, the average height person M sets the ankle angle θ1 to 90 °, the knee angle θ2 to 125 °, the bending angle θ4 between the upper body and the thigh from the hip to the shoulder to 95 °, and When sitting on the driver's seat 1 with the rhino angle θ3 set to 17 °, the eye point Im of the average height person M may be made to coincide with the appropriate line L inclined forward and downward at an angle of about 8 °, for example. The front and rear reference position, the vertical reference height, and the reference inclination angle of the seat cushion 1a are set so as to be able to do so.

  In the standard sitting state of the average height person M, the elbow angle θ5 and the side angle θ6 are set within the above range so that the steering handle 92 can be properly gripped. Furthermore, as shown in FIG. 14, the sole heel part Km of the pedal operation foot is placed at a predetermined position on the inclined surface part 14 formed from the rear part of the upper surface plate of the movable floor part 36, and the ankle angle θ1 is set. While being set to 90 ° and the inclination angle θ7 of the sole with respect to the horizontal line being set to about 52 °, for example, the appropriate position of the stepped portion 4a provided on the movable pedal member 17 of the accelerator pedal 4, that is, the stepped portion 4a The accelerator pedal 4 is disposed at a position where the palm ball part Bm of the sole can be brought into contact with the vertical center part.

  In FIG. 13, Hm is the hip point (sitting reference point) of the average height person M seated on the driver's seat 1. Further, in this embodiment, as shown in FIG. 14, the reference position on which the average height person M places the heel part Km of the pedal operation foot is set on the upper surface plate of the movable floor part 36 at the intermediate lift position, for example. is doing. That is, in the state where the installation height of the movable floor portion 36 is set at an intermediate position in the up-and-down movement range, the heel portion Km of the average height person M is placed at a substantially central portion (reference position) in the front-rear direction of the top plate. The movable floor portion 36 is disposed so as to be placed.

  The sole height dimension of the average height person M is about 255 mm, and the distance from the heel part Km to the lion ball part Bm is about 176 mm. Therefore, the movable pedal member from the reference placement position of the heel part Km. The vertical distance Ym to the stepping portion 4a of 17 is about 139 mm (≈176 mm × sin 52 °). Further, a horizontal distance Xm from the average height M's buttocks Km to the stepped portion 4a of the movable pedal member 17 is about 108 mm (≈176 mm × cos 52 °).

  Then, when the driver sitting on the driver's seat 1 is changed from the average height person M to a tall person T having a height of 190 cm, for example, as shown in FIG. The hip point Ht located on the seat cushion 1a is moved about 85 mm backward from the front / rear reference position Hm for the average height person M by operating the outer front / rear position adjustment switch, etc. The hip point Hs is moved downward by about 20 mm and the tilt angle of the seat cushion 1a is changed so that the rhino angle θ3 is about 20.0 °.

  Thus, if the upper body of the tall person T having a long arm compared to the average tall person M is moved backward, the eye point It of the tall person T having a higher sitting height than the average tall person M can be obtained. The steering handle 92 can be gripped in an appropriate state by moving it to the lower rear side so that it can coincide with the appropriate line L and appropriately changing the elbow angle θ5 and the side angle θ6. When a telescopic mechanism and a tilt mechanism that support the installation position and the installation angle of the steering handle 92 are provided, the tall person T greatly changes its elbow angle θ5 and side angle θ6. The steering handle 92 can be gripped without causing the above-mentioned comfort posture.

  Further, the back surface of the tall person T tends to rotate clockwise in the side view with the lion ball Bt as a fulcrum according to the backward movement and the downward movement of the seat cushion 1a. By lowering the movable floor 36 and reducing the knee angle θ2 to about 120 °, the ankle angle θ1 of the pedal operation foot is maintained at 90 ° and the inclination angle θ7 of the sole is an appropriate angle of about 52 °. In this way, the palm ball part Bt of the tall person T can be brought into contact with the appropriate position of the stepped part 4 a of the accelerator pedal 4.

  Specifically, since the sole dimension of the tall person T is about 285 mm and the distance from the heel part Kt to the lion ball part Bt is about 198 mm, as shown in FIG. The vertical distance Yt from the mounting position of the buttocks Kt of the tall person T to the stepped portion 4a of the movable pedal member 17 is about 156 mm (≈198 mm × sin 52 °), and the same distance Ym (139 mm) of the average height M ) About 17 mm longer. That is, the height placement position of the tall person T is about 17 mm lower than the average tall person M. The horizontal distance Xt from the heel portion Kt of the tall person T to the stepped portion 4a of the movable pedal member 17 is about 122 mm (≈198 mm × cos 52 °), and the same distance Xm (108 mm) of the average tall person M. Is about 14 mm longer.

  As described above, there is a difference of about 17 mm between the height placement position of the tall person T and the height placement position of the average height person M, and the position of the height placement position in the front-rear direction of both of them. There is a difference of about 14 mm between them. Therefore, in the state where the tall person T places the heel part Kt of the pedal operation foot on the movable floor portion 36, the lever ball part Bt of the pedal operation foot is accurately set with respect to the appropriate position of the stepping portion 4a. In order to make contact, the movable part is moved based on a difference of 17 mm in the height of the collar part placement and a vertical difference of −5 mm (≈−14 mm × tan 20 °) corresponding to the difference of 14 mm in the longitudinal direction of the collar part placement position. It is necessary to lower the installation position of the floor portion 36 by about 12 mm (≈17 mm−5 mm).

  That is, in the present embodiment in which the inclination angle α of the inclined surface portion 14 is set to 20 °, the movable floor portion 36 is lowered to the vicinity of the lowermost position set about 12 mm below the reference position. As a result, the rising amount of the movable floor portion 36 is set to approximately zero. In this way, the movable floor portion 36 is positioned approximately 12 mm below the reference position for the average height person M, so that the tall person T places the heel part Kt on the movable floor portion 36. In addition, the pedal operation can be appropriately performed in a state where the lever ball portion Bt of the pedal operation foot is in contact with the stepping portion 4a of the accelerator pedal 4.

  Moreover, according to the operation | movement which descends the movable floor part 36 by the said raising / lowering drive part 37, the inclined surface part 14 by the side of the accelerator pedal 4 and the inclined surface part 41 by the side of the footrest 7 will be displaced below simultaneously. In this way, the heel placement heights of the left and right feet are adjusted so that the right foot that operates the accelerator pedal 4 and the like in a side view and the left foot on which the back of the foot is placed on the footrest 7 have the same angle, This prevents the left and right foot angles from becoming unbalanced.

  On the other hand, when the driver sitting on the driver's seat 1 changes from an average stature M to a short stature S, such as a female driver having a height of 150 cm, for example, as shown in FIG. S moves the hip point Hs located on the seat cushion 1a forward by about 105 mm from the front / rear reference position Hm for the average height M by operating a front / rear position adjustment switch (not shown). In conjunction with this, the hip point Hs is moved upward by about 25 mm, and the tilt angle of the seat cushion 1a is changed so that the rhino angle θ3 is about 10.5 °.

  In this way, if the upper body of the short stature S having a short arm compared to the average height M is moved forward, the eye point Is of the short stature S having a low sitting height compared to the average height M is obtained. By moving to the upper front side of the vehicle body, it can be matched with the appropriate line L, and the elbow angle θ5 and side angle θ6 can be appropriately changed, or the telescopic mechanism and tilt mechanism (not shown) can be operated. By changing the installation height and installation angle of the steering handle 92, the steering handle 92 can be gripped in an appropriate state.

  Further, since the back surface of the short stature S tends to rotate counterclockwise around the lever ball portion Bs in a side view according to the forward movement and the upward movement of the seat cushion 1a, it corresponds to this. By raising the movable floor 36 and increasing the knee angle θ2 to about 130 °, the ankle angle θ1 of the operating foot is maintained at 90 °, and the inclination angle θ7 of the sole is set to an appropriate angle (52 °). The short stature person S can make the lever ball portion Bs of the operating foot abut on the appropriate position of the stepped portion 4a of the accelerator pedal 4 while maintaining the above.

  Specifically, since the sole dimension of the short stature S is about 225 mm and the distance from the heel part Ks to the lion ball part Bs is about 155 mm, as shown in FIG. The vertical distance Ys from the placement position of the buttocks Ks of the tall person S to the stepped portion 4a of the movable pedal member 17 is about 122 mm (≈155 mm × sin 52 °), and the same distance Ym (139 mm) of the average height person M. ) By 17 mm. Correspondingly, the height of the buttocks on the short stature S is 17 mm higher than the average stature M. Note that the horizontal distance Xs from the buttocks Ks of the short stature S to the stepped portion 4a of the movable pedal member 17 is about 95 mm (≈155 mm × cos 52 °), and the same distance Xm ( 108 mm) is about 13 mm shorter.

  There is a difference of about 17 mm between the height of the buttocks S of the short stature S and the height of the average height M of the buttocks. There is a difference. Therefore, in the state where the short stature S places the heel part Ks of the pedal operation foot on the movable floor part 36, the lever ball part Bs of the pedal operation foot is accurately set to the appropriate position of the stepping part 4a. In order to make contact with the flange, the height difference of 17 mm and the vertical difference of −4 mm (≈−13 mm × tan 20 °) corresponding to the difference between the front and rear of the flange placement position of 13 mm are as described above. It is necessary to raise the installation position of the movable floor portion 36 by about 13 mm (= 17 mm-4 mm).

  That is, in the present embodiment in which the inclination angle α of the inclined surface portion 14 is set to 20 °, the uppermost position of the movable floor portion 36 is about 13 mm above the reference position and from the accelerator pedal 4. Is set to be slightly lower than the lower end position (lower end hinge portion 16) of the operation pedal, so that the lift amount of the movable floor portion 36 from the lowermost position shown in FIG. 3 to the uppermost position shown in FIG. Yes. Then, the movable floor portion 36 is raised to the uppermost position and is positioned about 13 mm above the reference position for the average height person M, so that the short stature person S is placed on the movable floor portion 36. The pedal operation can be appropriately performed in a state where the portion Ks is placed and the lever ball portion Bs of the pedal operation foot is in contact with the stepping portion 4a of the accelerator pedal 4.

  Moreover, by raising the movable floor portion 36 by the elevating drive portion 37, the inclined surface portion 14 on the accelerator pedal 4 side and the inclined surface portion 41 on the footrest 7 side can be simultaneously displaced upward. Therefore, the support state of the non-pedal operating foot by the footrest 7 can be changed so that the installation angle of the left foot placed on the footrest 7 is the same angle as the pedal operating foot (right foot). It is possible to prevent the foot angle from becoming unbalanced.

  In the vehicular driving posture adjusting apparatus in which the operation pedal including the accelerator pedal 4 and the like operated by the driver is disposed in front of the driver seat 1 installed on the floor panel 9 of the passenger compartment as described above. The floor portion height that adjusts the driver's buttocks placement height by moving up and down the buttocks placement region on the floor panel 9 on which the driver's buttocks are placed when the operation pedal is depressed. The operation pedal includes a pedal base member 18 that is fixed to the floor panel 9 and a movable pedal member 17 that is pivotally supported by the pedal base member 18 and is stepped on by the driver. Further, the pivotal support portion of the movable pedal member 17, that is, the lower-end hinge portion 16 is located in front of the buttocks placement region (movable floor portion) 36 that is driven up and down by the floor height adjusting means 15. Because you provided, by properly adjusting the driving position with a simple structure, the operating pedal by the driver can operate properly.

  That is, in the first embodiment, the floor height adjusting means 15 is provided with the movable floor portion 36 that is supported by the floor panel 9 so as to be movable up and down, and the lift drive portion 37 that drives the movable floor portion 36 up and down. Since the movable floor portion 36 is displaced up and down by the elevating drive unit 37, the height of the heel portion of the pedal operation foot is adjusted, so that the sole size is smaller than that of the average height person M. It is desirable to perform a delicate pedal operation with the buttocks of the pedal operation foot (right foot) placed on the floor surface, regardless of whether the height S or the tall person T having a large sole size. There is an advantage that the accelerator pedal 4 can be appropriately operated with a simple configuration.

  Then, as shown in FIG. 3, when the movable floor portion 36 in the buttocks placement region of the pedal operation foot for stepping on the movable pedal member 17 constituting the accelerator pedal 4 comprising an organ pedal is lowered, It is inevitable that the lower end hinge portion 16 of the movable pedal member 17 and the heel portion of the pedal operation foot are separated from each other in the vertical direction. For this reason, when the movable pedal member 17 is stepped on, the movable pedal member 17 and the pedal operation foot may swing and displace along different paths, and the front surface of the buttocks may come into contact with the movable pedal member 17. As described above, by disposing the lower end hinge portion 16 of the movable pedal member 17 in front of the movable floor portion 36 of the floor height adjusting means 15, the heel portion of the pedal operation foot is placed on the movable floor portion 36. It is possible to effectively prevent the front surface of the collar from coming into contact with the accelerator pedal 4 when the accelerator pedal 4 is stepped on in a state where the accelerator pedal 4 is placed.

  Further, as shown in FIG. 5, when the movable floor portion 36 is raised for the short stature person S, the front portion of the heel portion becomes the movable pedal member 17 because the heel portion Ks is positioned on the front side. Although there is a tendency to come into contact with each other, as described above, the lower person S of the short stature S can move by arranging the lower end hinge portion 16 of the movable pedal member 17 in front of the movable floor portion 36 of the floor height adjusting means 15. It is possible to effectively prevent the front surface of the buttocks from coming into contact with the accelerator pedal 4 when the accelerator pedal 4 is stepped on with the buttocks of the pedal operation foot placed on the movable floor portion 36. Therefore, while ensuring the operability of the accelerator pedal 4 composed of the organ-type pedal, the floor portion height adjusting means 15 can appropriately adjust the buttocks placement position of the pedal operation foot according to the physique of the driver. There are advantages.

  In particular, as shown in the first embodiment, it is positioned at the lower end of the accelerator pedal 4 above the uppermost position of the movable floor 36 that is driven up and down by the up and down drive 37 of the floor height adjustment means 15. In the case where the lower end hinge portion 16 is disposed, this does not cause a situation in which the up-and-down displacement of the movable floor portion 36 is hindered due to interference with the operation pedal comprising the accelerator pedal 4. The movable floor portion 36 can be appropriately moved up and down.

  Moreover, in the said 1st Embodiment, when the said movable floor part 36 raises with the skin material 12 of the floor mat 13 installed so that the upper surface of the movable floor part 36 driven up and down by the floor part height adjustment means 15 may be covered. Since foreign matter intrusion prevention means for preventing foreign matter from entering below is configured, foreign matter such as an empty bottle is provided below the gap formed between the floor mat 13 and the movable floor 36 as it rises. Can be reliably prevented from entering and biting. Therefore, even though the fixed floor portion composed of the floor panel 9 that forms the bottom surface of the passenger compartment and the movable floor portion 36 are provided in the heel mounting region of the pedal operating foot as described above, the foreign matter is provided. There is an advantage that it is possible to effectively prevent the lifting and lowering operation of the movable floor portion 36 from being hindered due to the biting.

  Furthermore, when the elastic member 48 that expands and contracts according to the up-and-down displacement of the movable floor 36 is provided in the skin material 12 of the floor mat 13 as in the first embodiment, wrinkles are formed on the skin material 12. By extending or contracting the expansion / contraction part 48 in accordance with the up-and-down displacement of the movable floor part 36 without causing a situation such as the skin material 12 being forcibly stretched, between the movable floor part 36 and the floor mat 13 There is an advantage that it is possible to prevent the formation of a gap and prevent foreign matter from entering below the movable floor portion 36 when it is raised.

  Moreover, in the said 1st Embodiment, it is in the buttock mounting area | region on the floor panel 9 in which a driver | operator's buttock is mounted at the time of depression operation of the accelerator pedal 4 which consists of an organ type pedal which operates the driving drive source of a vehicle. Since the movable floor portion 36 is arranged to be moved up and down, it is desirable to perform a delicate pedal operation with the heel portion of the pedal operation foot placed on the buttock placement region on the floor panel 9. There is an advantage that the operation pedal including the accelerator pedal 4 can be appropriately operated with a simple configuration.

  It is possible to form the upper surface of the buttocks placement area on the floor panel 9 in a horizontal plane, but as shown in the first embodiment, the rear portion of the upper surface plate provided on the movable floor portion 36. In the case where the inclined surface portion 14 is provided in the rear region of the buttock mounting region by suppressing the upward and downward displacement amount of the movable floor portion 36 from increasing, The ankle angle θ1 and the inclination angle θ7 of the sole are greatly deviated from the appropriate angle for any of the short stature S having a smaller sole dimension than the average height M and the tall person T having a large sole dimension. There is an advantage that the height of placing the heel portion of the pedal operation foot can be adjusted so that the pedal operation can be performed in an appropriate posture without causing the above situation.

  That is, as shown in the first embodiment, the heel portion placement position of the short stature S is positioned about 13 mm forward compared to the average stature M, and the inclined surface portion 14 is about 20 °. When tilted forward at an angle, the amount of upward movement can be reduced by about 4 mm (≈13 mm × tan 20 °) compared to the case where the buttock mounting region on the floor panel 9 is formed horizontally. it can. Further, in the case of a tall person T configured to position the buttock placement position about 14 mm rearward compared to the average height person M, the buttock placement area on the floor panel 9 is formed horizontally. Compared to the case, the downward movement amount of the inclined surface portion 14 can be reduced by about 5 mm (≈14 mm × tan 20 °), and between the short stature person S and the high stature person T, the buttocks placement area is horizontal. Compared with the case where it forms in, up and down movement amount can be reduced 9 mm in total.

  In addition, according to the structure in which the inclined surface portion 14 that is inclined forward and upward is provided in the buttock mounting region on the floor panel 9 as described above, the heel portion of the pedal operation foot is mounted on the inclined surface portion 14. Thus, when a frontal collision occurs, the inclined surface portion 14 can suppress the heel portion of the pedal operation foot from moving forward in accordance with the impact load. There is an advantage that it is possible to effectively improve the performance and to more effectively prevent the front surface of the collar from coming into contact with the operation pedal.

  When the inclination angle α of the upper surface of the inclined surface portion 14 is larger than 23.5 °, the heel portion of the pedal operation foot placed on the inclined surface portion 14 slides backward according to the reaction force during the pedal operation. Since there is a tendency to fall easily, by setting the inclination angle α to 23.5 ° or less, it is possible to prevent slippage of the flange Ks and obtain a stable mounting state of the flange. desirable. In addition, when the inclination angle α of the upper surface of the inclined surface portion 14 is less than 13.5 °, an effect of suppressing an increase in the amount of displacement of the movable floor portion 36 is not sufficiently obtained. It is desirable to set the inclination angle α to 13.5 ° or more.

  Furthermore, in the said 1st Embodiment, the floor part height adjustment means 15 which has the support base 19, the movable floor part 36, the raising / lowering drive part 37 grade | etc., And the pedal base member 18 of the accelerator pedal 4 which consists of said organ type pedal. Since it is unitized so that it can be integrally assembled to the vehicle body, there is an advantage that the assembling work of the accelerator pedal 4 and the floor height adjusting means 15 can be performed easily and appropriately.

  As shown in the above embodiment, when the inclined surface 41 serving as the footrest adjusting means for adjusting the foot support state by the footrest 7 is provided on the left side portion of the movable floor portion 36 located on the rear side of the footrest 7. In a side view by simultaneously raising and lowering both the inclined surface portion 14 on the accelerator pedal 4 side and the inclined surface portion 41 on the footrest 7 side in accordance with the above-described operation of moving the movable floor portion 36 up and down by the elevating drive unit 37. It is possible to simultaneously adjust the hip placement heights of the left and right feet so that the left foot for operating the accelerator pedal 4 and the like and the foot angle of the left foot on which the back of the foot is placed on the footrest 7 are the same angle. Accordingly, the installation angle of the pedal operation foot (right foot) Rl indicated by the solid line in FIG. 16 and the installation angle of the non-pedal operation foot (left foot) indicated by the broken line Ll can be prevented from being left-right unbalanced. There are advantages such as being able to prevent a sense of incongruity.

  In particular, in the first embodiment, as shown in FIG. 2 and FIG. 4, the recessed portion 40 that is recessed downward is formed in the rear side portion of the clutch pedal 6 that is located at the center in the vehicle width direction of the movable floor portion 36. Since the structure is provided, the tilted surface portion 14 on the accelerator pedal 4 side and the tilted surface portion 41 on the footrest 7 side are moved up and down at the same time according to the above-described operation of moving the movable floor portion 36 up and down by the lift driving unit 37. Nevertheless, when the driver depresses the clutch pedal 6 with the left foot, it is possible to prevent the pedal operation from being hindered when the buttocks abut against the movable floor portion 36.

  Further, in the first embodiment, the region where the driver's sole palm ball part (for example, Bm) abuts on the movable pedal member 17 of the accelerator pedal 4 and the stepping operation is performed is predetermined as viewed from the side. Since the stepped portion 4a is formed of a convex surface portion that protrudes in an arc shape toward the rear side of the vehicle with a radius of curvature of the vehicle, the driver uses the pivot portion (lower end) of the pedal portion of the pedal operation foot (for example, Km). When the accelerator pedal 4 is stepped on with a predetermined distance from the hinge part 16), the contact position of the back of the shoe with respect to the stepped part 4a is raised and lowered as the amount of stepping changes. There is an advantage that it is possible to effectively prevent the driver from feeling uncomfortable even in the case where a situation that shifts occurs.

  That is, the stepped portion of the movable pedal member 17 may be formed in a straight line shape or may be curved so as to protrude toward the front side of the vehicle in a side view according to the shoe back surface. However, in the case of such a structure, the contact of the back of the shoe with the pedal tread as the stepping amount of the movable pedal member 17 increases with the stepped portion and the back of the shoe in contact with each other. Since the position changes while intermittently slipping to the toe side, it is inevitable that this change is clearly perceived by the driver and feels uncomfortable.

  On the other hand, as shown in the first embodiment, the stepped portion 4a disposed on the upper portion of the movable pedal member 17 is curved so as to protrude toward the rear side of the vehicle in a side view. In this case, the back surface of the shoe abuts against one point (for example, a step center point) of the stepped portion 4a formed of the convex surface portion in a line-contact state. Therefore, if a tall person T or the like steps on the accelerator pedal 4 with the buttocks Kt of the pedal operation foot positioned on the rear side of the vehicle body by a predetermined distance from the pivotal support portion of the movable pedal member 17, As the amount changes, the contact position of the shoe back with respect to the stepped portion 4a changes smoothly and continuously so as to roll, effectively preventing the driver from feeling uncomfortable. Can do. In addition, in order to change smoothly and continuously so that the contact position of the shoe back surface with respect to the stepped portion 4a rolls in accordance with the change in the amount of depression of the accelerator pedal 4, the stepped portion 4a is configured. It is desirable to set the radius of curvature of the arcuate convex surface portion within the range of 120 mm to 200 mm, and the most preferable radius of curvature is around 150 mm.
