  Further, since the seat slide lower rail 51 is installed on the vehicle body floor in a state of being inclined forwardly, the seat slide upper rail 52 and the seat cushion 1a of the driver seat 1 are When the vehicle is moved to the front side of the vehicle along the seat slide lower rail 51, the seat cushion 1a is pushed upward in conjunction with this. Conversely, when the seat slide upper rail 52 and the seat cushion 1a of the driver's seat 1 are moved to the rear side of the vehicle body along the seat slide lower rail 51 by the front / rear position adjusting mechanism 2, the seat cushion is interlocked with this movement. 1a descends.

  The seat slide upper rail 52 is provided with an inclination angle adjusting mechanism 3 that changes the inclination angle of the seat cushion 1a of the driver's seat 1. As shown in FIGS. 9 and 10, the inclination angle adjusting mechanism 3 is installed on the cushion frame 61 provided on the left and right side portions of the seat cushion 1 a and the upper surface of the front portion of the seat slide upper rail 52. A front bracket 62 and a front link 63 that support the front end of the frame 61, a rear bracket 64 that is installed on the rear upper surface of the seat slide upper rail 52 and supports the rear portion of the cushion frame 61, and a triangular rear link 65, a connecting shaft 66 that connects the rear end portions of the left and right rear links 65 and the rear lower ends of the cushion frames 61, and the upper surface of the central portion of the seat slide upper rail 52, and is attached to the rear link 65. A central link 67 for transmitting the driving force and a central bracket 68 for supporting the central link 67; A connecting link 69 which connects the upper portion of the central link 67 to the front end of the rear link 65, and a following drive shaft 70, the drive lever 71 and the tilt driving unit 72.

  The central link 67 has a lower end fixed to a drive shaft 70 extending in the vehicle width direction, and is rotatably supported by the central bracket 68 via the drive shaft 70. A drive lever 71 for rotating the drive shaft 70 is fixed to the drive shaft 70. Further, the central bracket 68 provided on one of the pair of left and right seat slide upper rails 52 (the outer side in the vehicle width direction) has a tilt drive unit 72 that drives the drive lever 71 fixed to the drive shaft 70. Is provided.

  As shown in FIGS. 12 and 13, the tilt drive unit 72 includes a screw shaft 74 having a front end portion connected to a tip end portion (lower end portion) of the drive lever 71 via a connection pin 73, and the screw shaft 74. A drive motor 75 and a gear mechanism 76 for rotationally driving, and a guide bracket 77 fixed to the front surface of the gear mechanism 76, and a base end portion of the guide bracket 77 via the support bracket 78. It is supported by. The gear mechanism 76 is provided with a worm gear 79 fixed to the output shaft 75a of the drive motor 75 and a worm nut 80 that is rotationally driven by the worm gear 79. A screw hole that is screwed onto the shaft 74 is formed.

  Then, as the worm nut 80 is rotationally driven by the driving force input from the drive motor 75 via the worm gear 79, the screw shaft 74 screwed with the worm nut 80 is rotated and screw-fed. It has become so. As the screw shaft 74 is screwed, the connecting pin 73 provided at the tip of the screw shaft 74 moves back and forth along the support groove 81 formed in the guide bracket 77, and the driving force thereof is connected to the connecting pin 73. Is transmitted to the drive lever 71 via the rotation, the drive lever 71 is oscillated and displaced, and the drive shaft 70 is rotationally driven.

  Further, as the drive shaft 70 is rotationally driven, the center link 67 is swung and displaced, and the driving force is transmitted to the rear link 65 via the connecting link 69, so that the rear link 65 is swung. In addition to the dynamic displacement, the inclination angle of the seat cushion 1a is adjusted by the swinging displacement of the front link 63 corresponding thereto. 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. 9, the front link 63 and the central link 67 are inclined backward, and the rear link 65 Since the connecting shaft 66 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 by the front / rear adjustment switch is performed, the drive motor 75 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 75 is transmitted through the gear mechanism 76, the screw shaft 74, the connecting pin 73, the driving lever 71 and the driving shaft 70 to the central link. 67, the central link 67 shifts from the rearward tilt state to the standing state shown in FIG. Then, as the central link 67 shifts to the standing state, the driving force is transmitted to the rear link 65 via the connecting link 69, and the front end portion of the rear link 65 is pulled to the front side of the vehicle. The connecting shaft 66 provided at the rear end portion of the rear link 65 is raised, and the rear end portion of the seat cushion 1a is driven to be pushed up accordingly.

  In addition, since the front link 63 shifts from the rearward tilted state to the standing state in conjunction with the swinging displacement of the rear link 65, the front end portion of the seat cushion 1a is moved upward 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 rearward movement angle of the seat cushion 1a is set to be larger than the upper movement amount of the front end portion of the seat cushion 1a, so that the rearward inclination angle of the seating surface is increased according to the upward movement of the seat cushion 1a. It changes so that it may become small gradually, and it is comprised so that it may approach a horizontal state. In conjunction with this, the inclination angle of the seat back 1b changes 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 75 of the tilt angle adjustment 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 75 is transmitted to the central link 67 through the gear mechanism 76, the screw shaft 74, the connecting pin 73, the drive lever 71 and the drive shaft 70. As a result, the seat cushion 1a is displaced from the upper position to the lower position shown in FIG. 9, and as the seat cushion 1a moves downward, the rearward tilt angle of the seat surface gradually increases, 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 sitting on the driver's seat 1 with respect to the eye point and the operation pedal also changes. Therefore, the driver who newly sits on the driver's seat 1 holds the steering handle 48 in an appropriate state while maintaining the comfortable posture and, for example, the accelerator pedal 4 including the convex portion 23 of the pedal body 18 and the like. The front / rear position adjustment mechanism 2 and the tilting mechanism are arranged so that the lever ball portion of the pedal operation foot is brought into contact with the proper position of the pedal 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-rear position and the like of the driver seat 1 by operating the angle adjustment mechanism 3.

  There is a possibility that drivers having various heights and shapes from the person with a height of 150 cm or less to a person with a height of 190 cm or more may be seated on the driver seat 1. It is necessary to configure so that the user can sit down and perform a proper driving operation. For example, as a result of statistically analyzing the comfort posture of the average height M, which is considered to be 173 cm, and the average height of the average height M, who is most likely to sit on the driver's seat 1, the following data is obtained. It was.

  The comfortable posture of the occupant seated on the driver's seat 1 means a seating posture that can stably 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. 15, the ankle angle θ1 of the pedal operation foot is about 85 ° to 95 °, the knee angle θ2 is about 120 °, and the upper body and the thigh are folded from the hip to the shoulder. The bending angle θ3 is about 95 °. In the case of the average height person M, the appropriate angle of the rhino angle θ4, which is the angle formed by the thighs with respect to the horizontal line, is a value obtained by adding approximately 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 48 can be properly operated is about 100 ° to 130 °, and the side angle θ6 is about 20 ° to 45 °.

  Accordingly, the average height person M sets the ankle angle θ1 to 90 °, the knee angle θ2 to 120 °, the bending angle θ3 between the upper body and the thigh from the hip to the shoulder, for example, to 95 °, and When sitting on the driver's seat 1 with the rhino angle θ4 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 as described above, the elbow angle θ5 and the side angle θ6 are set within the above range, and the steering handle 48 can be properly gripped. Further, as shown in FIG. 16, the heel portion Km of the pedal operation foot is placed at a predetermined position on the first inclined floor portion 13, and the inclination angle θ7 of the sole surface with respect to the horizontal line is set to about 47 °, for example. In this state, the lever position Bm can be brought into contact with an appropriate position of the accelerator pedal 4, for example, an upper portion of the convex surface portion 23 close to the flat surface portion 24 provided on the pedal body 18. Further, the accelerator pedal 4 is provided. In FIG. 15, Hm is the hip point (sitting reference point) of the average height person M seated on the driver's seat 1. In the present embodiment, as shown by the solid line in FIG. 16, the reference position where the average height person M places the heel part Km of the pedal operation foot is set, for example, on the substantially central part in the front-rear direction of the first inclined floor part 13. Is set.

  When the driver seated on the driver seat 1 changes from the average height person M to the short height person S such as a female driver as shown by the phantom lines in FIG. 1 and FIG. 15, the short height person S Operates the front / rear position adjustment mechanism 2 and the inclination angle adjustment mechanism 3 so that the eye point Is can be matched with the appropriate line L while ensuring the handle operability and the pedal operability. The seat cushion 1a of the seat 1 is moved forward, and in response to this, an operation of increasing the installation height of the seat cushion 1a and decreasing the inclination angle of the seat cushion 1a with respect to the horizontal line is performed.

  For example, when a short stature person S having a height of 150 cm sits on the driver's seat 1, the hip point Hs located on the seat cushion 1a is set to, for example, 105 mm from the front and rear reference position Hm for the average height person M. In addition to being moved forward, the hip point Hs is moved upward by about 25 mm in conjunction with this, and the tilt angle of the seat cushion 1a is changed so that the rhino angle θ4 is about 12 °. . As a result, the upper body of the short stature S with short arms compared to the average height M can be moved forward to grip the steering handle 48 in an appropriate state, and the sitting height compared to the average height M can be increased. By moving the eye point Is of the low short stature S to the upper front side of the vehicle body, it can be matched with the appropriate line L.

  Further, since the pedal operating foot of the short stature S tends to move upward in the front part of the vehicle body in accordance with the forward movement and upward movement of the seat cushion 1a, the knee angle θ2 is set to about 125 ° correspondingly. In this way, the flat surface of the pedal body 18 of the accelerator pedal 4 is provided with the lever ball portion Bs of the pedal operation foot made of the right foot of the short stature S while maintaining the ankle angle θ1 at an appropriate angle. It is possible to make it abut on an appropriate position composed of an upper portion of the convex surface portion 23 close to the surface portion 24.

  Since the distance (about 155 mm) from the buttocks Ks of the short stature S to the palm ball Bs is about 25 mm shorter than the same distance (about 180 mm) of the average stature M, the short stature S When trying to bring the lever ball portion Bs of the pedal operation foot into contact with the appropriate position of the accelerator pedal 4 while maintaining the sole inclination angle θ7 at the same angle (47 °) as that of the average height person, Ks is positioned about 18 mm (= sin 47 ° × 25 mm) above the buttocks Km of the average tall person M. For this reason, if the short stature S does not allow the pedal-operated foot's heel Ks to float above the floor panel 9, the pedal-operated foot's lion sphere Bs is set to an appropriate value of the convex-shaped portion 23. When the heel portion Ks of the pedal operating foot cannot be accurately brought into contact with the upper portion or the like, and the heel portion Ks of the pedal operation foot is floated above the floor panel 9, a delicate pedal with the heel portion Ks as a fulcrum is used. It becomes difficult to perform the operation properly.

  However, when the inclination angle α of the first inclined floor portion 13 is set to 15 °, as shown by the phantom line in FIG. 16, the short stature person S changes the inclination angle θ7 of the sole of the foot, for example, from 47 ° to 52 °. And by moving the heel part Ks of the pedal operation foot forward by about 28 mm from the reference position on the first inclined floor part 13 (positioning position of the heel part Km of the average height person M). The lever ball Bs is placed on the front portion of the first inclined floor portion 13 located about 7.5 mm above the rear extension portion 13a, and the lever ball portion Bs is placed on the accelerator pedal 4 in the state. The accelerator operation can be performed by abutting at an appropriate position composed of an upper portion of the convex surface portion 23 provided on the surface.

  Note that the ankle angle θ1 of the pedal operation foot tends to be smaller than 90 ° in response to the inclination angle θ7 of the foot sole changing from 47 ° to about 52 °. In response to the increase, the short stature S sets its knee angle θ2 to about 125 ° and extends the knee more easily than the tall stature (see FIG. 1), so that the ankle angle θ1 exceeds the appropriate range. It is possible to prevent it from becoming smaller, for example, 85 ° or less.

  On the other hand, as shown in FIG. 17, when a tall person T having a height of, for example, 186 cm sits on the driver's seat 1, the hip point Ht located on the seat cushion 1a is used for the average height person M. The seat cushion is moved backward from the front and rear reference position Hm, for example, by about 85 mm, and in conjunction with this, the hip point Hs is moved downward by about 20 mm, and the rhino angle θ4 is set to about 22.0 °. It operates so that the inclination angle of 1a may be changed. As a result, the upper body of the tall person T having a long arm compared to the average tall person M can be moved rearward to hold the steering handle 48 in an appropriate state, and the sitting height is higher than that of the average tall person M. By moving the eye point It of the tall person T to the lower rear side of the vehicle body, it can be matched with the appropriate line L.

  Further, since the pedal operating foot of the tall person T tends to move downward in the rear part of the vehicle body in accordance with the backward movement and downward movement of the seat cushion 1a, the knee angle θ2 is set to about 115 ° correspondingly. By reducing the height, the tall person T prevents the ankle angle θ1 from becoming 95 ° or more, while the lever ball portion Bt of the pedal operation foot is moved from the accelerator pedal 4 including the convex surface portion 23 or the like. It is possible to abut on the proper depression position.

  Since the distance (about 195 mm) from the buttocks Kt of the tall person T to the egg ball part Bt is about 15 mm longer than the same distance (about 180 mm) of the average tall person M, the height of the tall person T When the sole inclination angle θ7 is maintained at the same angle (47 °) of the tall person M and the mounting position of the heel part Kt is set to the same position, the heel against the convex part 23 of the accelerator pedal 4 and the like It is necessary to displace the contact position of the child ball part Bt by about 11 mm (= sin 47 ° × 15 mm) below the average height person M.

  In the above-described embodiment, the sole inclination angle θ7 of the tall person T is changed from, for example, about 47 ° to 44 °, and the heel portion Kt is disposed behind the first inclined floor portion 13 as shown in FIG. Or the rear extension 13a provided on the rear side thereof, the lever ball Bt of the tall person T is properly brought into contact with the appropriate position of the accelerator pedal 4. It is possible to perform a stepping operation. The ankle angle θ1 of the pedal operation foot tends to be larger than 90 ° corresponding to the inclination angle θ7 of the foot sole changing from about 47 ° to about 44 °. The knee angle θ2 is set to a value smaller than 120 °, for example, about 115 °, and the knee is bent (see FIG. 17), so that the ankle angle θ1 increases beyond the appropriate range. For example, it can be prevented that the angle becomes 95 ° or more.

  In the vehicle in which the driver's seat 1 is disposed above the floor panel 9 that forms the bottom of the passenger compartment as described above, and the operation pedal including the accelerator pedal 4 is installed in front of the driver's seat 1. The operation pedal includes a pedal base portion 19 fixed to the floor panel 9 and a pedal body 18 supported so as to be able to swing around a pivot portion including a support shaft 17 provided on the pedal base portion 19. In front of the driver's seat 1, a first inclination in which a buttocks placement area on the floor panel 9 on which the buttocks of the pedal operation feet are placed when the operation pedal is depressed is inclined upward. Since the floor portion 13 is provided and the rear mounting portion 30 for attaching the pedal base 19 to the floor panel is provided in front of the front end portion of the first inclined floor portion 13, the driver seat seat is provided. At if the driver physique seated is variously changed to be an advantage that each can be properly depressing the operation pedal organ type.

  That is, in the said embodiment, since the 1st inclination floor part 13 in which the upper surface inclined upwards was formed in the collar part mounting area | region located in the back side of the operation pedal which consists of the accelerator pedal 4 grade | etc., FIG. As shown in FIG. 1, even if the height of the short S is shorter than that of the average height M, the heel portion Ks of the pedal operation foot is placed on the front portion of the first inclined floor portion 13. In this state, with the heel part Ks positioned relatively upward, while maintaining the ankle angle θ1 and the inclination angle θ7 of the sole, the lever ball part Bs is, for example, an accelerator pedal. The accelerator pedal 4 and the like can be stepped on while being brought into contact with a stepping operation portion made up of the convex surface portion 23 and the like provided in FIG.

  Accordingly, the pedal operation foot of the short stature S is in a state of being separated from the floor surface, so that a delicate pedal operation becomes impossible, or the ankle angle θ1 and the inclination angle of the sole of the foot The short stature S can place the heel portion Ks of the pedal operation foot on the first inclined floor portion 13 without making it difficult to quickly depress the operation pedal due to the great deviation of θ7 from the appropriate angle. There is an advantage that a delicate pedal operation of the accelerator pedal 4 and the like can be performed with the lever ball portion Bs in contact with the appropriate position (convex surface portion 23) of the accelerator pedal 4 while being placed. is there.

  In the case of a tall person T, for example, as shown in FIG. 17, if the foot inclination angle θ7 of the pedal operation foot is decreased and the knee angle θ2 is decreased, the buttocks Kt is moved downward as much. Without this, the lever ball part Bt of the pedal operating foot can be easily and properly brought into contact with the appropriate position (convex surface part 23) of the accelerator pedal 4 or the like. Accordingly, as shown in FIG. 18, the tall person T operates the pedal including the accelerator pedal 4 and the like with the buttocks Kt of the pedal operation foot placed on the rear portion of the first inclined floor portion 13. It is possible to perform the subtle stepping operation properly.

  Then, as described above, the rear mounting portion 30 of the pedal base portion 19 constituting the so-called organ-type accelerator pedal 4 that is supported so as to be swingable about the pivot portion provided at the lower end portion of the pedal body 18 is a first. The pedal operability improving function by providing the first inclined floor portion 13 whose upper surface is inclined forward and upward at a predetermined angle because it is disposed in front of the front end portion of the inclined floor portion 13, that is, placing the heel portion There is an advantage that the pedal base 19 can be stably attached to the bottom of the passenger compartment without impairing the height adjusting function.

  Furthermore, in the above embodiment, the rear mounting portion 30 for attaching the pedal base portion 19 to the floor panel 9 is disposed on the front side of the support shaft 17 that supports the lower end portion of the pedal body 18. While effectively preventing the influence of the impact load input to the installation portion of the rear mounting portion 30 from reaching the buttocks of the pedal operation foot placed on the rear side of the support shaft 17, the pedal base portion 19. Can be stably attached to the bottom of the passenger compartment, and by providing the first inclined floor portion 13, there is an advantage that the height of the driver's buttocks can be adjusted appropriately.

  Further, in the above embodiment, the first inclined floor portion 13 is constituted by the heel pad material 11 and the like separate from the floor panel 9, and the front end portion of the first inclined floor portion 13 is the rear end portion of the pedal base portion. Since the first inclined floor portion 13 can be installed at an appropriate position with a simple configuration, the impact load input when the vehicle collides is affected by the rear of the support shaft 17. There is an advantage that it can be effectively prevented from reaching the buttocks of the pedal operation foot placed on the side.

  In particular, in the above-described embodiment, the rigidity that can stably support the heel when the pedal is depressed while the heel of the pedal operation foot is placed on the first inclined floor 13, and the second The heel pad material is made of a material having a flexibility capable of absorbing an impact load acting on the heel when a collision accident occurs with the heel of the pedal operation foot placed on the inclined floor portion 13. 11 is formed, the pedal operability is lowered due to the heel pad material 11 being too soft, or the impact absorbing function at the time of collision is impaired due to the heel pad material 11 being too hard. Without any problem, the first inclined floor portion 13 can appropriately adjust the driver's buttocks placement height. Then, the rear mounting portion 30 of the pedal base portion 19 is arranged on the front side of the support shaft 17 that supports the lower end portion of the pedal body 18, thereby comprising the locking pin 45 and the like of the rear mounting portion 30. When the rigid member is separated from the heel pad material 11, the impact absorbing function at the time of collision by the heel pad material 11 can be properly maintained.

  Further, as shown in the above embodiment, when the heel pad material 11 constituting the first inclined floor portion 13 is provided with a notch portion 15 into which the rear end portion of the pedal base portion 19 is inserted. By using the pedal base 19 fixed to the floor panel 9 as a positioning member for the heel pad material 11, there is an advantage that the heel pad material 11 can be stably locked to the floor panel 9 with a simple configuration. .

  In the above embodiment, the floor mat member 12 is installed on the floor panel 9 positioned in front of the driver seat 1 and the upper surface of the first inclined floor portion 13 is covered with the floor mat member 12. In addition, while effectively improving the appearance of the bottom of the passenger compartment, the function of adjusting the height of the heel portion by providing the first inclined floor portion 13 whose upper surface is inclined forward and upward at a predetermined angle is not impaired. There is an advantage that the pedal base portion 19 can be stably attached to the bottom of the passenger compartment by the rear attachment portion 30 or the like.

  Further, in the first embodiment, as shown in FIG. 6, since at least the rear part of the floor mat material 12 is fixed to the floor panel 9 by the fastening device 41, the floor mat material 12 is configured with a simple configuration. There is an advantage that it can be installed stably. That is, in a state where the driver's lower limbs are placed on the floor mat material 12, a load acts in a direction in which the floor mat material 12 is mainly pushed forward. Therefore, at least the rear portion of the floor mat material 12 is There is an advantage that a stable installation state can be obtained by effectively restricting the movement of the floor mat member 12 by locking with the fastening tool 41 or the like.

  In the above-described embodiment, on the floor panel 9 on which the buttocks of the pedal operation foot for depressing the so-called suspension pedal type clutch pedal 6 disposed on the side of the operation pedal including the accelerator pedal 4 and the brake pedal 5 is located. The accelerator pedal 4 and the brake pedal are provided in the buttock region because the second inclined floor portion 14 whose upper surface is inclined upwardly at a slant angle, for example, an inclination angle β of about 10 °, compared to the first inclined floor portion 13 is provided. Pedal operation when the clutch pedal 6 is stepped on while preventing a large level difference between the first inclined floor portion 13 and the second inclined floor portion 14 disposed on the rear side of the clutch 5. There is an advantage that it is possible to effectively prevent a sense of incongruity caused by the buttocks of the foot contacting the floor surface.

  In addition, when the inclination angle α of the first inclined floor portion 13 with respect to the horizontal plane is set to a value larger than 15 °, the buttocks of the pedal operation foot placed on the first inclined floor portion 13 slip down. When the inclination angle α of the first inclined floor portion 13 is set to a value smaller than 15 °, the mounting height of the buttocks is adjusted according to the physique of the driver. Since the function cannot be obtained sufficiently, it is desirable to set the inclination angle α of the first inclined floor portion 13 with respect to the horizontal plane to about 15 °.

  When the inclination angle β of the second inclined floor portion with respect to the horizontal plane is set to a value larger than 10 °, the pedal operability of the pedal operation foot comes into contact with the second inclined floor portion 14 and the pedal operability is improved. And when the inclination angle β of the second inclined floor portion 14 is set to a value smaller than 10 °, there is a gap between the first inclined floor portion 13 and the second inclined floor portion 14. Therefore, it is desirable that the inclination angle β of the second inclined floor portion 14 with respect to the horizontal plane is set to about 10 °.

  Moreover, in the said embodiment, the connection part 16 which connects smoothly the upper surface of the 1st inclination floor part 13 by the side of the accelerator pedal 4 and the brake pedal 5 and the upper surface of the 2nd inclination floor part 14 by the side of the clutch pedal 6 is provided. Therefore, the appearance deteriorates due to the formation of a step between the upper surface of the first inclined floor portion 13 and the upper surface of the second inclined floor portion 14 due to the difference between the inclination angles of the two. Can be effectively suppressed, and it is possible to suppress the feeling of discomfort caused by the pedal operating foot coming into contact with the step.

  Further, when the operation pedal including the accelerator pedal 4 and the brake pedal 5 is depressed as described above, the front ascending portion provided in the buttock mounting region on the floor panel 9 on which the buttock of the pedal operation foot is mounted. The upper surface of the first inclined floor portion 13 that is inclined to the rear is inclined rearwardly downward and exceeds the buttock placement region where the heel portion of the pedal operation foot is placed when the operation pedal is depressed. In the case where the rear extension 13a extending rearward is provided, the state is changed from a state where the tall person T slowly depresses the accelerator pedal 4 or the brake pedal 5 to a sudden operation state in which the amount of depression is suddenly increased. It is possible to effectively prevent the driver from feeling uncomfortable due to the sliding resistance acting on the rear end portion of the first inclined floor portion 13 when the heel portion of the pedal operating foot contacts the rear end portion of the first inclined floor portion 13. Benefits That.

  For example, the rear extension portion 13a is omitted, and the floor panel 9 on which the heel portion of the pedal operation foot is placed when the operation pedal including the accelerator pedal 4 and the brake pedal 5 is depressed as shown in FIG. It is also conceivable to adopt a structure in which a horizontal floor surface 131 is installed at the rear part of the first inclined floor part 13 that is inclined forwardly and is provided in the heel part mounting area. However, when configured in this manner, a tall person T having a large sole dimension places the heel portion Kt of the pedal operation foot on the horizontal floor surface 131 and the foot portion of the accelerator pedal 4 There is a case where the pedal operation is performed in a state where the pedal is in contact with the stepping operation portion (convex surface portion 24). In this state, when shifting to the sudden operation state in which the amount of depression of the accelerator pedal 4 or the like is suddenly increased, the first inclined floor portion 13 is moved by moving the heel portion Kt of the pedal operation foot forward. And the horizontal floor surface 131 abuts on the boundary portion 132 to cause sliding resistance, which may cause the driver to feel uncomfortable.

  On the other hand, as shown in FIG. 18 and the like, when a rear extension 13a whose upper surface is inclined downward is provided at the rear of the first inclined floor 13, the tall person T is placed on the rear extension 13a. From the slow operation state where the pedal operation foot is operated slowly by placing the heel portion Kt of the pedal operation foot and bringing the foot tip portion into contact with the stepping operation portion (convex surface portion 24) of the accelerator pedal 4 When shifting to a sudden operation state in which the amount of depression of the accelerator pedal 4 or the like is suddenly increased, the pedal operation foot heel Kt is smoothly slid forward along the rear extension 13a, thereby the pedal. There is an advantage that it is possible to effectively prevent a sense of incongruity during operation.

  Moreover, as shown in the said embodiment, the installation height of the back extension part 13a is located below the floor surface F of the circumference | surroundings, By this, the rear part of the said inclination floor part 13 is more than the floor surface F of the circumference | surroundings. When the recessed portion 49 is also recessed downward, the floor surface F is installed as in the case where the installation height of the floor surface F is set to the same height as the rear end portion of the rear extension 13a. The tall person T feels uncomfortable when the pedal is operated without the height becoming excessively low, or conversely, the front end portion of the inclined floor portion 13 projecting greatly upward from the floor surface F. There is an advantage that can be effectively prevented.

  Moreover, in the said embodiment, the accelerator pedal 4 requested | required to perform delicate pedal operation in the state which mounted the buttocks of the pedal operation leg | foot on the upper side of the floor panel 9 of a compartment is fixed to the floor panel 9. A pedal base 19 and a so-called organ-type pedal including a pedal body 18 that is pivotably supported by a pivot portion including a support shaft 17 provided on the pedal base 19. Since the first inclined floor portion 13 is disposed in the buttock placement region on the floor panel 9 on which the heel of the foot is placed, regardless of the physique of the driver seated on the driver seat 1 There is an advantage that the pedal operation of the accelerator pedal 4 can be appropriately performed with a simple configuration.

  Further, as shown in the above-described embodiment, the accelerator pedal is provided with a convex surface portion 23 formed of a curved surface having a curvature radius R1 of, for example, about 100 mm to 200 mm that bulges to the driver's seat side (rear side) in a side view. In the case of the structure, the pressing position of the accelerator pedal 4 can be changed smoothly and continuously by rolling the contact position of the shoe back surface along the convex surface portion 23. Accordingly, the lever ball portion of the accelerator pedal 4 is separated from the installation portion of the support shaft 17 provided at the lower end portion of the pedal body 18 of the accelerator pedal 4. Even if the convex portion 23 is displaced in the vertical direction according to the stepping operation, it is possible to effectively prevent the driver from feeling uncomfortable.

  As described above, a flat surface portion having a radius of curvature larger than that of the convex portion 23, for example, a flat surface extending linearly obliquely upward in a side view when the radius of curvature is set to infinity. Instead of the above-described embodiment in which the convex portion 24 is connected to the upper end portion of the convex portion 23, the entire upper portion of the pedal body 18 constituting the accelerator pedal 4 is a convex surface formed of a curved surface having a predetermined radius of curvature. It is also possible to make a part. However, according to this configuration, when a tall person T whose foot sole size is large and whose toe portion is separated above the pedal body 18 depresses the accelerator pedal 4 with the pedal operation foot. In addition, since the toe portion and the lower portion are largely separated from the upper portion of the pedal body 18, it is impossible to perform the stepping operation in a state where the foot back surface is in contact with the pedal body 18 in a side view. In some cases, the driver may feel uneasy when operating the pedal.

  On the other hand, as shown in the above-described embodiment, when the flat surface portion having a larger radius of curvature than the convex surface portion 23 is provided at the upper end portion of the convex surface portion 23, the tall person The driver can rest assured that the pedal can be depressed in a state in which the sole of the foot is brought into contact with both the convex surface portion 23 and the flat surface portion 24 of the pedal body 18 to contact the surface. The accelerator pedal 4 can be depressed with a feeling.

  In place of the above-described embodiment in which the first inclined floor portion 13 is provided at the installation portion of the accelerator pedal 4 and the brake pedal 5, as shown in FIG. 20, the pedal operation foot that operates the brake pedal 5 is depressed. A second inclined floor portion 14 that is inclined forward and upward at an angle β is provided in the flange mounting area on the floor panel 9 on which the section is mounted and the flange area on the clutch pedal 6 side. The inclination angle β of the portion 14 may be set to a gentler angle than the inclination angle α of the first inclined floor portion 13 located on the accelerator pedal 4 side.

  Moreover, in the said embodiment, while moving the driver's seat 1 back and forth, the front-back position adjustment mechanism 2 and the inclination angle adjustment mechanism 3 which reduce the back inclination angle of the seat cushion 1a according to the front movement of this driver's seat 1. Therefore, the driver sitting on the driver's seat 1 appropriately sets the driving characteristics of the front / rear position adjusting mechanism 2 and the inclination angle adjusting mechanism 3 according to the height of the driver's seat 1 so that the driver's sitting posture While maintaining the above, the front and rear positions of the driver's seat 1 and the inclination angle of the seat cushion 1a are automatically adjusted so that the eye point coincides with the appropriate line L, and excellent handleability and pedal operability can be obtained. There is an advantage that it can be adjusted.

  Even when the seating position or the like of the driver seated on the driver seat 1 changes according to the adjustment operation of the front and rear position of the driver seat 1 and the inclination angle of the seat cushion 1a, the driver seat 1 is positioned at the feet of the driver. By forming the first inclined floor portion 13 and the like on the floor panel 9 to be performed, a short stature S having a short sole dimension places the heel portion Ks of the pedal operation foot on the first inclined floor portion 13 and the like. In this state, while maintaining the ankle angle θ1 and the inclination angle θ7 of the sole of the foot at an angle suitable for the operation of the accelerator pedal 4 or the like, the above-mentioned palm ball portion Bs of the short stature S is formed in the convex shape of the accelerator pedal 4. There is an advantage that the pedal operability can be ensured by contacting the portion 23.

  In the above embodiment, the driver's seat 1 is automatically moved back and forth according to the driver's switch operation by the front / rear position adjusting mechanism 2 and the tilt angle adjusting mechanism 3, and the driver seat 1 is moved forward. In the example described above, the rearward tilt angle of the seat cushion 1a is reduced. However, the front / rear position of the driver's seat 1 and the rearward tilt angle of the seat cushion 1a are changed by the driver's manual operation. It may be configured.
