That is, at the retracted position where the seat cushion 1a of the driver's seat 1 is moved to the rear side of the vehicle body, the front link 73 and the center link 77 are inclined rearward and the rear link 75 as shown in FIG. 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. 6, 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 20 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. 12, 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. 13, the sole heel part Km of the pedal operation foot is placed at a predetermined position on the inclined surface part 11 formed from the rear part of the upper surface plate 41, and the ankle angle θ1 is set to 90 °. In addition, in a state where the inclination angle θ7 of the sole with respect to the horizontal line is set to about 52 °, for example, the proper position of the stepped portion 20 provided on the movable pedal member 17 of the accelerator pedal 4, that is, the vertical direction of the stepped portion 20 The accelerator pedal 4 is disposed at a position where the palm ball portion Bm on the sole can be brought into contact with the response portion.

  In FIG. 12, Hm is the hip point (sitting reference point) of the average height person M seated on the driver's seat 1. Moreover, in this embodiment, as shown in FIG. 13, the reference position on which the average height person M places the heel part Km of the pedal operation foot is, for example, on the upper surface plate 41 of the movable floor part 36 in the intermediate ascending position. It is set. 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 at the substantially center portion (reference position) in the front-rear direction of the top plate 41. 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 17 stepping portions 20 is about 139 mm (≈176 mm × sin 52 °). The horizontal distance Xm from the average height person M's heel Km to the stepped portion 20 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 changes from the average height M to a tall 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 °.

  In this way, 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 high sitting height compared to the average tall person M is obtained. By moving to the lower rear side of the vehicle body, it can be matched with the appropriate line L, and the steering handle 92 can be gripped in an appropriate state by 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.

  In addition, the back surface of the tall person T tends to rotate clockwise around the lever ball portion Bt in a side view 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 °. It is possible to make the above-mentioned tall ball T's palm ball part Bt abut on the appropriate position of the stepped part 4a of the accelerator pedal 4 while maintaining the height.

  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.

  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, the foot sole of the short stature S tends to rotate counterclockwise as viewed from the side with the lion ball Bs as a fulcrum as the seat cushion 1a moves forward and upward. 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 °). Thus, the short stature S can make the lever ball portion Bs of the operating foot abut on the appropriate position of the stepping portion 4 a of the accelerator pedal 4.

  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 movable floor portion 36 is raised to the uppermost position set about 13 mm above the reference position. Thus, the amount of movement of the movable floor 36 from the lowermost position is set to approximately 25 mm. In this way, the movable floor portion 36 is positioned approximately 13 mm above the reference position for the average stature person M, so that the short stature person S places the heel portion Ks on the movable floor portion 36. In addition, the pedal operation can be properly performed in a state where the lever ball portion Bs of the pedal operation foot is in contact with the stepping portion 4a of the accelerator pedal 4.

  As described above, for a vehicle including a driver's seat 1 installed on a floor panel 9 of a passenger compartment and an operation pedal including an accelerator pedal 4 and the like that is depressed by a driver seated on the driver's seat 1. In the driving posture adjusting device, the driver's heel placement height is adjusted by moving the heel placement area on the floor panel 9 on which the driver's heel portion is placed during the depression operation of the operation pedal. The physique and seating of the driver who sits on the driver's seat 1 with the front / rear width and the front / rear position of the saddle placement region which has the placement height adjustment means 12 and is driven up and down by the saddle placement height adjustment means 12 Since the setting is based on the foremost position and the rearmost position of the buttocks that change depending on the posture, the driver sitting on the driver's seat 1 properly adjusts the operation pedal by appropriately adjusting the driving posture with a simple configuration. Can be operated There is an advantage in that.

  In other words, in the first embodiment, the movable floor portion 36 supported by the floor panel 9 so as to be movable up and down, and the lift drive unit 37 that drives the movable floor portion 36 to move up and down are provided in the heel mounting height adjusting means 12. In addition, the front and rear width and front and rear position of the movable floor portion 36 disposed in the saddle placement region on the floor panel are determined by the driver composed of the tall person T and the short person S who are seated on the driver seat 1. Since it is set based on the foremost position and the rearmost position of the buttocks that change depending on the physique and the sitting posture, the movable floor portion 36 and the It is possible to prevent the raising / lowering drive unit 37 from becoming large and complicating its structure, and what is the short stature S having a smaller sole dimension than the average tall person M or the tall person T having a large sole dimension? Even, there is an advantage that it is possible to perform the proper pedal operation while placing the heel on the inclined surface portion 11 of the movable floor portion 36.

  For example, in the first embodiment, since the rear end position 36b of the movable floor portion 36 is set to a position about 155 mm behind the stepping center point 20a of the accelerator pedal 4, the tall person T having a height of about 190 cm With the sole angle θ7 set to about 52 ° and the buttocks Kt placed on the front side of the rear end position 36b of the upper surface plate 41 provided on the movable floor portion 36, the pedal operation foot The lever pedal Bt can be brought into contact with the stepping portion 20 of the accelerator pedal 4 so that the accelerator pedal 4 can be properly depressed (see FIG. 3).

  Further, as described above, the front end position 36a of the movable floor portion 36 is set to a position about 65 mm behind the stepping center point 20a of the accelerator pedal 4, so that the short stature person S having a height of about 150 cm In a state where θ7 is set to about 52 ° and the collar portion Ks is placed on the rear side of the front end position 36a of the upper surface plate 41 provided on the movable floor portion 36, the lever ball portion Bs of the pedal operating foot is placed. Can be brought into contact with the stepping portion 20 of the accelerator pedal 4 to properly depress the accelerator pedal 4 (see FIG. 5).

  When the front and rear width of the movable floor portion 36 is set to about 90 mm by setting the front end position 36a and the rear end position 36b of the movable floor portion 36 as shown in the first embodiment, the driver seat The movable floor portion 36 does not increase in size and complexity of the movable floor portion and its lifting mechanism as in the case where the foot portion of the seat 1 is displaced up and down over substantially the entire region. Can be easily driven up and down, so that the weight of the vehicle body can be effectively reduced and the manufacturing cost of the vehicle driving posture adjusting device can be reduced.

  Although it is possible to form the upper surface of the basket mounting area on the floor panel 9 in a horizontal plane, as shown in the first embodiment, the rear portion of the upper surface plate 41 provided on the movable floor portion 36. In the case where the inclined surface portion 11 is provided in the heel mounting region by inclining the front side upward, the average height person M is suppressed while suppressing the increase and decrease drive range of the movable floor portion 36 from being increased. If the height of the sole S is small or the height of the sole T is large, the ankle angle θ1 and the inclination angle θ7 of the sole are greatly deviated from appropriate angles. There is an advantage that the pedal can be operated in an appropriate posture without any trouble.

  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 11 is positioned at an angle of about 20 °. In the case of inclining forward, the amount of upward movement can be reduced by about 4 mm (≈13 mm × tan 20 °), compared to the case where the eaves mounting area on the floor panel 9 is formed horizontally. 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 heel placement area on the floor panel 9 is formed horizontally. In comparison with this, the downward movement amount of the inclined surface portion 11 can be reduced by about 5 mm (≈14 mm × tan 20 °).

  Moreover, in the case where the inclined surface portion 11 inclined forward is provided in the heel 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 11. In the state, when the front collision accident occurs, the inclined surface portion 11 can suppress the heel portion of the pedal operation foot from moving forward according to the impact load. There is also an advantage that safety can be effectively improved.

  If the inclination angle α of the upper surface of the inclined surface portion 11 is larger than 23.5 °, the heel portion of the pedal operation foot placed on the inclined surface portion 11 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 11 is less than 13.5 °, an effect of suppressing an increase in the lift drive range of the movable floor portion 36 cannot be sufficiently obtained. It is desirable to set the inclination angle α to 13.5 ° or more.

  In the first embodiment, the operation pedal composed of the accelerator pedal 4 for operating the traveling drive source of the vehicle is moved to the movable pedal member 17 that is depressed by the driver, and the pedal base member that is fixed to the floor panel 9. 15 and an upright displacement area on the floor panel 9 on which the driver's buttocks are placed when the accelerator pedal 4 is depressed. There is an advantage that the accelerator pedal 4 which is desired to be delicately operated with the heel portion of the pedal operation foot placed on the heel placement region on the panel 9 can be appropriately operated with a simple configuration. .

  Further, in the first embodiment, the saddle placement height adjusting means 12 having the support pedestal 13, the movable floor portion 36, the raising / lowering drive portion 37, and the like, the pedal base member 15 of the accelerator pedal 4 including the organ pedal, 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 saddle placement height adjusting means 12 can be performed easily and appropriately.

  In the first embodiment, a 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 20 formed of a convex surface portion that protrudes in an arc shape toward the rear side of the vehicle with a curvature radius of 5 mm is provided, 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 depressed with the predetermined distance from the hinge portion 16) on the rear side of the vehicle body, the abutment position of the shoe back with respect to the depression portion 20 rises and falls as the depression amount 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 arcuate convex surface portion that is curved so that the stepping portion 20 disposed on the upper portion of the movable pedal member 17 protrudes toward the rear side of the vehicle in a side view. In this case, the back of the shoe comes into contact with one point of the stepped portion 20 (for example, the stepped center point 20a) made 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 stepping portion 20 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 stepping portion 20 may roll in accordance with the change in the amount of depression of the accelerator pedal 4, the stepping portion 20 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.

  In the first embodiment, the front / rear position adjusting mechanism 2 and the inclination angle adjustment that move the driver's seat 1 back and forth and reduce the rearward inclination angle of the seat cushion 1a according to the forward movement of the driver's seat 1. Since the seat adjustment mechanism including the mechanism 3 and the like is provided, the driver sitting on the driver's seat 1 appropriately sets the drive characteristics of the front and rear position adjustment mechanism 2 and the inclination angle adjustment mechanism 3 according to the height of the driver. Thus, while maintaining the driver's seating posture, the front and rear positions of the driver's seat 1 and the seat cushion 1a are adjusted so that the eye point is aligned with the appropriate line L, and excellent handle operability and pedal operability are obtained. There is an advantage that the inclination angle and the like can be automatically adjusted.

  When the driver sitting on the driver seat 1 operates the saddle placement height adjusting means 12 in conjunction with the operation of adjusting the front and rear position and the inclination angle of the seat cushion 1a, Regardless of the physique of the driver, the ankle angle θ1 and the inclination angle θ7 of the sole are the angles suitable for the operation of the accelerator pedal 4 and the like with the buttocks placed on the inclined surface portion 11. The driver's heel mounting height can be automatically adjusted so that the driver can ensure pedal operability by bringing the lever ball portion into contact with the stepping portion 20 of the accelerator pedal 4 while maintaining There is an advantage.

  In the first embodiment, the driver's seat 1 is automatically moved back and forth according to the driver's switch operation by the seat adjustment mechanism including the front / rear position adjustment mechanism 2 and the inclination angle adjustment mechanism 3. The example in which the rearward inclination angle of the seat cushion 1a is reduced in accordance with the forward movement of the driver seat 1 has been described. However, the driver can manually operate the front and rear positions of the driver seat 1 and the seat cushion 1a. You may comprise so that a back inclination angle may be changed.

  Further, in the above-described diamond 1 embodiment, an example in which the heel placement area on the floor panel 9 on which the driver's buttock is placed is moved up and down when the accelerator pedal 4 made of an organ pedal is depressed. As described above, as in the second embodiment shown in FIG. 15, the vehicle includes an accelerator pedal 4 ′ composed of a suspension pedal supported swingably with the upper end pivotal support 4 a provided on the dash panel 7 as a fulcrum. Of course, the present invention is applicable. In the vehicle having the accelerator pedal 4 ′ composed of the suspension pedal as described above, it is not necessary to support the accelerator pedal 4 on the support pedestal 13 that supports the movable floor portion 36, so that the structure can be simplified. It is.

  16 and 17 show a third embodiment of the vehicle driving posture adjusting apparatus according to the present invention.
