Since it is installed close to both ends, the floor board is disposed between the vehicle body floor mat 60 laid along the vertical surface portions 1a and 2a and both ends of the floor board 5 in the vehicle width direction. Regardless of the vertical position of 5, a substantially constant gap is formed.

  The occupant seat 4 is a separate type seat separately installed on the driver seat side and the passenger seat side in the front part of the passenger compartment. The seat cushion 35 that constitutes the seating surface of the occupant, and the seat cushion 35 A seat back 36 that rises upward from the rear end portion and a headrest 37 attached to the upper end portion of the seat back 36, and a seat position adjusting mechanism 38 provided on the vehicle body floor 3, The vertical position and the installation angle with respect to the vehicle body floor 3 are supported in an adjustable manner.

  As shown in FIGS. 8 and 9, the seat position adjusting mechanism 38 includes a pair of left and right guide rails 39 installed on the vehicle body floor 3 in an upwardly inclined state, and a seat cushion 35 along the guide rails 39. Slide drive means 40 that slides in the front-rear direction of the vehicle body, and tilt means 41 that moves the rear end of the seat cushion 35 up and down in conjunction with the forward and backward movement of the seat cushion 35.

  The seat cushion 35 has a cushion frame 42 disposed so as to cover the main body (cushion material) from below, and below the cushion frame 42 is a U-shaped member having an open upper surface. The guide rail 39 is provided. Inside the guide rail 39, a slider 44 having a projecting piece 45 protruding on the upper surface is slidably disposed, and an upper end portion of the projecting piece 45 is connected to a lower portion of the cushion frame 42 via a connecting pin 46. It is pivotally supported. The slider 44 is formed with a screw hole into which the screw shaft 47 of the slide driving means 40 is screwed.

  The screw shaft 47 of the slide drive means 40 is disposed in the guide rail 39, and both front and rear end portions are rotatably supported by bearing members, and the rear end portion is driven via a power transmission cable (not shown). It is connected to the motor. A driving force is transmitted from the drive motor to the screw shaft 47 via a power transmission cable, and the screw shaft 47 is driven to rotate so that the slider 44 is screwed along the guide rail 39. It is configured. A driving cable 48 that transmits a driving force to the lifting drive mechanism 6 of the floor board 5 is connected to the front end portion of the screw shaft 47 via a coupling 49.

  The tilt means 41 of the seat position adjusting mechanism 38 includes a support plate 50 protruding below the rear portion of the cushion frame 42, a guide plate 51 fixed to the side surface of the guide rail 25 and vertically installed, The guide plate 51 has a guide pin 52 projecting from the support plate 50, and the guide plate 51 is formed with a guide groove 53 having an upwardly inclined portion, and the guide pin 52 slides along the guide groove 53. It is supported freely. Then, the slider 44 is screwed by the screw shaft 47 of the slide drive means 40 and the front portion of the seat cushion 35 moves back and forth along the guide rail 25 in the guide groove 53 of the guide plate 51. As the guide pin 52 slides along, the rear portion of the seat cushion 35 is driven up and down.

  For example, when the seat cushion 35 is slid and displaced from the rear position shown in FIGS. 1 and 8 to the front position shown in FIG. 10 by the slide driving means 40, the front portion of the seat cushion 35 extends along the guide rail 39. The guide pin 52 slides to the front side of the vehicle body along the guide groove 53 of the guide plate 51, and the rear end portion of the seat cushion 35 is pushed up to raise the seat cushion 35. Swings and displaces. As a result, according to the forward movement of the seat cushion 35, the inclination angle with respect to the horizontal plane is gradually reduced, and the seat cushion 35 is placed in a nearly horizontal installation state. It will be displaced closer.

  When a short occupant A is seated on the occupant seat 4, the occupant seat 4 is moved to the front side of the vehicle body by operating an operation switch (not shown) to activate the drive motor of the slide drive means 40. When the slide displacement is performed, the front portion of the seat cushion 35 rises along the guide rail 25 and the rear portion of the seat cushion 35 is pushed up as shown in FIG. The hip point representing the movement of the occupant A matches the height of the occupant A so that the line of sight of the occupant A coincides with the appropriate line L. Further, the rear end portion of the seat cushion 35 is pushed up according to the forward movement of the occupant seat 4 so that the installation angle becomes almost horizontal, so that the foot length is shortened according to the height. Since the tall person A is seated in a state where the knee is largely bent and the lower part of the knee is suspended at a predetermined angle, it is possible to prevent the feet from being separated from the floor surface.

  On the other hand, when the tall occupant B is seated on the occupant seat 4, if the occupant seat 4 is slid to the rear side of the vehicle body by the slide drive means 40, as shown in FIG. The front portion of the seat cushion 35 is lowered along the guide rail 25 and the rear portion of the seat cushion 35 is pushed down. Therefore, the hip point representing the seating center of the occupant B with respect to the seat cushion 35 corresponds to the height of the occupant B. Then, the line of sight of the occupant B coincides with the appropriate line L by moving downward in the rear part. Further, when the seat cushion 35 is in a forwardly inclined state in accordance with the rearward movement of the occupant seat 4, the tall person B whose leg length increases according to the height decreases the knee bending angle. Then, since the lower part of the knee is extended forward, a stable seating posture can be obtained.

  The driving cable 48 for transmitting the driving force of the slide driving means 40 to the lifting / lowering driving mechanism 6 of the floor board 5 is made of a cable material rotatably supported by a flexible outer cylinder, and its distal end portion 11 is introduced into the first transmission box 61 as shown in FIG. In the first transmission box 61, as shown in FIG. 12, a worm gear 62 that is connected to the tip end portion of the drive cable 48 and rotates integrally therewith, and a worm wheel 63 that is rotationally driven by the worm gear 62 are provided. The worm wheel 63 is formed with an engagement hole into which a spline shaft 65 projecting from the lower second transmission box 64 is inserted and engaged. The rotational force of the drive cable 48 is transmitted to the worm wheel 63 via the worm gear 62, whereby the worm wheel 63 is rotationally driven and the rotational force is transmitted to the second transmission via the spline shaft 65. It is transmitted to the box 64.

  In the second transmission box 64, a first bevel gear 66 that rotates integrally with the spline shaft 65, and a second bevel gear 67 that is rotationally driven by the first bevel gear 66 are disposed. The second bevel gear 67 is fixed so that the drive cable 33 of the elevating drive mechanism 6 rotates integrally, so that the rotational force of the second bevel gear 67 is applied to the drive cable 33 of the elevating drive mechanism 6. It is configured to be transmitted. Note that a reduction mechanism comprising the worm gear 62 and the worm wheel 63 is disposed between the drive cable 48 of the slide drive means 40 and the drive cable 33 of the elevating drive mechanism 6 so that the slide drive means. When the rotational drive force is transmitted from the 40 drive cables 48 to the drive cable 33 of the lift drive mechanism 6, the rotational speed is reduced to about 1/10.

  The second transmission box 64 is disposed on the front side of the cross member 24 disposed on the front side of the occupant seat 4 and is fixed to the vehicle body floor 3 with mounting bolts. In a state where the one transmission box 61 is overlaid, these are integrally connected by a connecting bolt. Further, when the second transmission box 64 and the first transmission box 61 are bolted, the spline shaft 65 is inserted into the engagement hole of the worm wheel 63 provided in the first transmission box 61. By doing so, they are connected together.

  When the slider 44 is screwed by the slide driving means 40 and the seat cushion 35 is moved back and forth along the guide rail 25, the driving force is applied to the driving cable 48 and the first and second transmission boxes 61 and 64. , The drive cable 33 and the screw shaft 32 are driven to rotate, and the slide block 34 is screwed in the longitudinal direction of the vehicle body. 31 is configured to shift from the lying state to the standing state, or from the standing state to the lying state, and the rear side portion of the front board 15 is driven up and down.

  For example, when the short stature person A sits on the occupant seat 4, when the occupant seat 4 is moved to the front side of the vehicle body, the drive link 31 shifts from the lying state to the standing state in conjunction with this, The rear side portion of the front board 15 of the floor board 5 is displaced to the raised position shown in FIGS. On the other hand, when the tall person B is seated on the occupant seat 4, when the occupant seat 4 is moved to the rear side of the vehicle body, the drive link 31 shifts from the standing state to the lying state in conjunction with this, The rear side of the front board 15 of the floor board 5 is displaced to the lowered position shown in FIG. Thus, the installation height of the floor board 5 on which the occupant's buttocks are placed is adjusted to a position suitable for the length of the legs of the occupants A and B.

  As described above, according to the above configuration, the upper surface of the floor board 5 installed on the vehicle body floor 3 so as to be movable up and down is configured separately from the vehicle body floor mat 60 covering the upper surface of the vehicle body floor 3. Since the floorboard mat 23 is covered, the floorboard mat 23 that independently covers only the floorboard 5 can easily follow the raising / lowering operation of the floorboard 5. As a result, the floor mat (the vehicle body floor mat 60 and the floor board mat 23) is laid on both the vehicle body floor 3 and the floor board 5 to improve the appearance of the floor portion and to smoothly move the floor board 5 up and down. It becomes possible to make it compatible without problems.

  Further, as in the above embodiment, the area located below the floor board 5 on the upper surface of the vehicle body floor 3 is also covered with the vehicle body floor mat 60, and the area is continuously covered with the other areas. In this case, it is possible to prevent a large opening of the vehicle body floor mat 60 from being formed at a position below the floor board 5, and gravel between the vehicle body floor mat 60 and the vehicle body floor 3 through the opening. There is an advantage that it is possible to effectively prevent a situation where a foreign object enters.

  Further, as in the above embodiment, the insulator 62 is installed only on the lower surface of the vehicle body floor mat 60, and the insulator 62 is not installed on the lower surface of the floorboard mat 23 that overlaps the vehicle body floor mat 60 in plan view. In such a case, the upper surface of the floor board mat 23 (the mounting surface of the feet of the occupant) is caused by the double installation of the insulator 62 while ensuring sufficient sound insulation of the floor portion. ) Can be prevented from becoming unnecessarily high, and there is an advantage that the comfort and riding comfort in the passenger compartment can be maintained in a good state.

  Further, as in the above-described embodiment, the floor board 5 is raised and lowered in the vertical direction when viewed from the front, and along the vertical surface portions 1a and 2a extending in the substantially vertical direction in proximity to both ends of the floor board 5 in the vehicle width direction. When the vehicle body floor mat 60 is laid, the floor board 5 can be raised and lowered while maintaining a small gap between the vehicle body floor mat 60 and both ends of the floor board 5. Therefore, there is an advantage that it is possible to effectively prevent a foreign matter such as dust from entering through the gap and to maintain a good appearance of the floor portion.

  Further, as in the above embodiment, the side sill 1 of the vehicle body and the side walls of the floor tunnel 2 are installed so as to extend in a substantially vertical direction, and the vertical surface portions 1 a and 2 a are formed by the side wall surface portions of the side sill 1 and the floor tunnel 2. In this case, both end portions of the floor board 5 installed so as to cover substantially the entire width direction between the side sill 1 and the floor tunnel 2, and the side wall surface portions (vertical surface portions 1a, 2a) of the side sill 1 and the floor tunnel 2 are used. The floor board 5 can be lifted and lowered while maintaining a small gap with the vehicle body floor mat 60 laid along the line. That is, when the floor tunnel 2 is formed in a constricted shape similar to a floor tunnel in a conventional vehicle, the gap between the side wall surface portion of the floor tunnel 2 and the floor board 5 increases as the floor board 5 rises. As a result, there is an increased risk of foreign matter such as dust entering from the enlarged gap, and the appearance of the floor portion is also impaired. Even in this case, for example, if the width dimension of the floor board 5 is enlarged by protruding the side portion of the floor board 5 sideways as the floor board 5 is raised, the above problem can be solved. However, the mechanism for enlarging the width dimension of the floor board 5 becomes complicated, and problems such as an increase in cost occur. On the other hand, according to the above-described embodiment, the gap between both ends of the floor board 5 can be maintained at a small value with a simple and rational configuration, and foreign matter can be prevented from entering from the gap and the appearance can be improved. It can be planned.

  Moreover, in the said embodiment, the floor board 5 is comprised from the front side board 15 and the rear side board 17 connected so that bending was possible, and it is the above-mentioned while folding in the mountain fold shape from the connection part of both these boards 15 and 17 as the starting point. Since the floor board 5 is moved up and down, the installation height of the floor board 5 does not occur without causing a situation that the front end portion or the rear end portion of the floor board 5 is greatly moved up and down and a large gap is generated in the portion. Can be adjusted easily and appropriately.
