[0009] Embodiments of the present invention will now be described in detail with reference to the drawings. In the drawings, arrow Fr indicates the front in the longitudinal direction of the vehicle, and arrow U indicates the upward direction in the vertical direction of the vehicle (hereinafter simply referred to as the vertical direction). Arrow L indicates the left side in the vehicle width direction when the vehicle is viewed from the rear towards the front. In the following description, "front" and "rear" correspond to the front and rear in the longitudinal direction of the vehicle, respectively, and "up" and "down" correspond to the up and down in the vehicle vertical direction, respectively. "Left" and "right" correspond to the left and right in the vehicle width direction when the vehicle is viewed from the rear towards the front.

[0010] Figure 1 is a perspective view of the vehicle cargo compartment structure 1 according to this embodiment, viewed from the left rear. As shown in Figure 1, the vehicle cargo compartment structure 1 is applicable to vehicles such as automobiles in which the passenger compartment S1 and the cargo compartment S2 are arranged within a single passenger compartment. A rear seat 2 is installed at the rear of the passenger compartment S1. The cargo compartment S2 is a space located behind the rear seat 2 within the passenger compartment, and in a plan view from above the vehicle, it is enclosed by the rear seat 2 and the right side wall, left side wall, and rear wall of the vehicle (not shown). Users such as passengers of the vehicle can access the cargo compartment S2, for example, through a back door opening (not shown) that is opened and closed by a back door (not shown).

[0011] The rear seat 2 has seat portions 21a and 22a positioned at intervals above the floor portion 3 that forms the floor surface of the vehicle, with space provided below the seat portions 21a and 22a. A seat rail 4 extending in the longitudinal direction of the vehicle is installed below the rear seat 2, and the seat portions 21a and 22a are attached to the seat rail 4 via a support frame 5 so as to be movable in the longitudinal direction of the vehicle. The rear seat 2 (specifically the seat portions 21a and 22a) can slide along the seat rail 4 in the longitudinal direction of the vehicle between the frontmost position, which is the movable end at the front of the vehicle, and the rearmost position, which is the movable end at the rear of the vehicle. Sliding the rear seat 2 forward expands the cargo area S2 forward of the vehicle. Figure 1 shows the rear seat 2 in the rearmost position.

[0012] In this embodiment, the rear seat 2 has a right seat 21 and a left seat 22 arranged in the vehicle width direction. The right seat 21 has a seat portion 21a and is positioned on the right side. The left seat 22 has a seat portion 22a and is positioned on the left side. The right seat 21 and the left seat 22 (specifically, the seat portions 21a and 22a) can slide independently of each other in the longitudinal direction of the vehicle between the rearmost position and the rearfront position. The seat back 21b of the right seat 21 and the seat back 22b of the left seat 22 can be reclined forward and backward by a reclining mechanism, respectively. Figure 1 shows both seat backs 21b and 22b in the upright position.

[0013] As shown in FIGS. 1 and 2, the vehicle luggage compartment structure 1 includes a luggage box 10 disposed at the lower part of the luggage compartment S2, a luggage board 20 placed on the luggage box 10, a slide board 30 placed on the luggage board 20, and a bracket 40 for attaching the slide wall 10B (described later) and the slide board 30 of the luggage box 10 to the rear seat 2. FIG. 2 is a perspective view of the luggage box 10, the luggage board 20, the slide board 30 and the bracket 40 as seen from the front of the vehicle.

[0014] As shown in FIGS. 3 to 5, inside the luggage box 10, a storage area S2a that is open upward and stores luggage is formed. FIG. 3 is a perspective view of the box body 10A (described later) of the luggage box 10 and the luggage board 20 as seen from the front of the vehicle. FIG. 4 is a perspective cross-sectional view of the luggage box 10 as seen from the left front, and FIG. 5 is a perspective cross-sectional view of the luggage box 10 as seen from the left rear. FIGS. 4 and 5 each show the right half of the luggage box 10.

[0015] The luggage box 10 has a bottom wall 11, a rear wall 12, a right side wall 13, a left side wall 14 and a front wall 15 that respectively define the lower end, rear end, right end, left end and front end of the storage area S2a. In other words, the storage area S2a is a space surrounded by the bottom wall 11, the rear wall 12, the right side wall 13, the left side wall 14 and the front wall 15. The storage area S2a is continuous in the vehicle front-rear direction from the rear wall 12 to the front wall 15 and continuous in the vehicle width direction from the right side wall 13 to the left side wall 14. The luggage box 10 is arranged so as to occupy substantially the entire area of the luggage compartment S2 in a plan view as seen from above the vehicle. The rear wall 12, the right side wall 13 and the left side wall 14 are respectively arranged adjacent to the rear wall, the right side wall and the left side wall of the vehicle, and the front wall 15 is arranged opposite to the rear wall 12 in the vehicle front-rear direction.

[0016] As shown in FIGS. 3 to 6, in the present embodiment, the luggage box 10 includes a box main body 10A and a slide wall 10B that is separate from the box main body 10A. FIG. 6 is an overall perspective view of the slide wall 10B as seen from the rear of the vehicle. The box main body 10A is installed on the floor portion 3 in the luggage compartment S2. The slide wall 10B is attached to the rear seat 2 from the rear side of the vehicle and is slidable in the vehicle front-rear direction with respect to the box main body 10A integrally with the rear seat 2.

[0017] The box main body 10A has a bottom wall 11, a rear wall 12, a right side wall 13, and a left side wall 14, and the slide wall 10B has a front wall 15. That is, the front wall 15 is separate from the other walls 11, 12, 13, 14 that form the storage area S2a. The front wall 15 extends downward from the rear portions of the seat portions 21a, 22a. By sliding the rear seat 2 in the vehicle front-rear direction, the front wall 15 slides in the vehicle front-rear direction with respect to the rear wall 12, and thereby the position of the front end of the storage area S2a is changed in the vehicle front-rear direction. Therefore, by sliding the rear seat 2 forward in the vehicle, the storage area S2a is expanded forward in the vehicle.

[0018] Specifically, as shown in FIG. 3, the box main body 10A is a box-shaped member that is open above and in front of the vehicle, and is generally rectangular in shape and long in the vehicle width direction in a plan view as seen from above the vehicle. The box main body 10A is formed of a foamed resin such as foamed polypropylene. The bottom wall 11 has a generally rectangular outer shape in a plan view as seen from above the vehicle, is horizontally arranged, and extends in the vehicle front-rear direction and the vehicle width direction. The bottom wall 11 extends forward of the vehicle beyond the position of the front wall 15 when the rear seat 2 is arranged at the frontmost position, and the front edge of the bottom wall 11 is arranged below the seat portions 21a, 22a at the frontmost position. The rear wall 12 extends upward from the rear edge portion of the bottom wall 11 and extends in the vehicle width direction over the entire width along the rear edge portion of the bottom wall 11.

[0019] The right side wall 13 extends upward from the right edge of the bottom wall 11 and extends forward along the right edge of the bottom wall 11 from the right edge of the rear wall 12 to the front edge of the bottom wall 11. The left side wall 14 extends upward from the left edge of the bottom wall 11 and extends forward along the left edge of the bottom wall 11 from the left edge of the rear wall 12 to the front edge of the bottom wall 11. The right side wall 13 and the left side wall 14 have notches that are recessed downward from the top surface, and the luggage board 20 can be placed vertically in the notches.

[0020] To prevent the front of the right side wall 13 from interfering with the right seat 21 at the rearmost position, the height of the upper edge of the front of the right side wall 13 gradually decreases towards the front of the vehicle. In other words, the upper edge of the front of the right side wall 13 slopes downward towards the front of the vehicle. Similarly, the height of the upper edge of the front of the left side wall 14 gradually decreases towards the front of the vehicle. In the illustrated example, in a side view from one side in the vehicle width direction, the right side wall 13 and the left side wall 14 each have a roughly rectangular rear portion with an upper edge of a constant height and a roughly right-angled triangular front portion.

[0021] In this embodiment, a tool storage section 18 is provided at the bottom of the box body 10A. The tool storage section 18 is located below the bottom wall 11 and has a recess 18a that opens into the bottom wall 11 and stores tools (for example, tools for vehicle repair). The user can store tools in the recess 18a and take tools out of the recess 18a through the storage area S2a. A removable luggage carpet 19 is laid on the bottom wall 11. The luggage carpet 19 is a flat plate-shaped member having an outer shape corresponding to the outer shape of the bottom wall 11 and covers the entire bottom wall 11. The luggage carpet 19 is formed from, for example, a flat plate made of corrugated plastic and a cloth covering the surface of the flat plate. The luggage carpet 19 forms the flat bottom surface of the storage area S2a and functions as a lid that closes the tool storage section 18 from above.

[0022] A notch 19a is formed in the edge of the luggage carpet 19 for the user to insert their fingers. In the illustrated example, the notch 19a is formed in the right rear corner of the luggage carpet 19 (see Figures 6 and 7). With the right seat 21 and left seat 22 in the frontmost position, the user can insert their fingers into the notch 19a and lift the luggage carpet 19 to open it upwards and access the recess 18a of the tool storage compartment 18.

[0023] Figure 7 shows the right sliding wall 10B1 (described later), which is attached to the right seat 21, among the sliding walls 10B. The sliding wall 10B is attached from the rear of the vehicle to the lower part of the rear seat 2 (specifically, the rear of the seat portions 21a and 22a) via brackets 40 and stays 6 (described later), etc. As shown in Figure 6, the front wall 15 is roughly rectangular in shape, elongated in the vehicle width direction, when viewed from one side in the vehicle's longitudinal direction. The front wall 15 extends in the vehicle width direction across almost the entire width of the bottom wall 11 and also extends downward from the rear of the seat portions 21a and 22a to the luggage carpet 19 or its vicinity. The front wall 15 closes the space between the rear of the seat portions 21a and 22a and the floor portion 3 from the rear of the vehicle, separating this space from the storage area S2a in the vehicle's longitudinal direction.

[0024] As shown in Figures 4 to 7, in this embodiment, the sliding wall 10B is separate from each other and has a right sliding wall 10B1 and a left sliding wall 10B2 arranged in the vehicle width direction. The right sliding wall 10B1 is located on the right side, and the left sliding wall 10B2 is located on the left side. The right sliding wall 10B1 is attached (fixed) to the rear of the seat portion 21a via a right bracket 41 (described later), etc., and slides integrally with the right seat 21 (specifically the seat portion 21a) in the vehicle longitudinal direction. The left sliding wall 10B2 is attached (fixed) to the rear of the seat portion 22a via a left bracket 42 (described later), etc., and slides integrally with the left seat 22 (specifically the seat portion 22a) in the vehicle longitudinal direction. In Figures 4, 5, and 7, only the right sliding wall 10B1 of the sliding wall 10B is shown. In this embodiment, the right sliding wall 10B1 and the left sliding wall 10B2 have the same structure as each other, except that they are symmetrical to each other.

[0025] The right sliding wall 10B1 has a right front wall 151 and a right intermediate wall 161, which constitute the right part (right half) of the front wall 15. The left sliding wall 10B2 has a left front wall 152 and a left intermediate wall 162, which constitute the left part (left half) of the front wall 15. The right front wall 151 and the left front wall 152 are each generally rectangular in shape when viewed from one side in the longitudinal direction of the vehicle, and extend in the vehicle width direction and the vertical direction. When the right seat 21 and the left seat 22 are positioned at the same position in the longitudinal direction of the vehicle, the right front wall 151 and the left front wall 152 are aligned in the vehicle width direction and form a generally flat front wall 15. When the right seat 21 and the left seat 22 are positioned at offset positions from each other in the longitudinal direction of the vehicle, the right front wall 151 and the left front wall 152 are positioned at offset positions from each other in the longitudinal direction of the vehicle. In Figure 6, the left front wall 152 is positioned offset forward of the vehicle relative to the right front wall 151.

[0026] The right intermediate wall 161 extends forward from the inner edge (left edge) in the vehicle width direction of the right front wall 151, and the left intermediate wall 162 extends forward from the inner edge (right edge) in the vehicle width direction of the left front wall 152. As shown in Figure 6, when the left front wall 152 is positioned in front of the vehicle relative to the right front wall 151, the space between the left edge of the right front wall 151 and the right edge of the left front wall 152 is blocked by the right intermediate wall 161. Similarly, when the right front wall 151 is positioned in front of the vehicle relative to the left front wall 152, the space between the left edge of the right front wall 151 and the right edge of the left front wall 152 is blocked by the left intermediate wall 162. Therefore, when the right seat 21 and the left seat 22 are positioned in an offset position, the right intermediate wall 161 or the left intermediate wall 162 prevents luggage from passing through the left edge of the right front wall 151 and the right edge of the left front wall 152 and leaving the storage area S2a.

[0027] In the illustrated example, the rear of the right intermediate wall 161 has the same height dimension as the right front wall 151. The upper edge of the front of the right intermediate wall 161 gradually slopes downward towards the front of the vehicle, similar to the front of the right side wall 13, so as not to interfere with the right seat 21. The rear of the left intermediate wall 162 has the same height dimension as the left front wall 152. The upper edge of the front of the left intermediate wall 162 gradually slopes downward towards the front of the vehicle, similar to the front of the left side wall 14, so as not to interfere with the left seat 22.

[0028] As shown in Figure 3, the luggage board 20 is a flat plate member extending in the vehicle width direction and the vehicle longitudinal direction, and in this embodiment, it is generally rectangular in plan view when viewed from one side in the vertical direction. The luggage board 20 divides the cargo compartment S2 vertically into a storage area S2a and the space above the storage area S2a, and functions as a lid that closes the storage area S2a from above, and as the floor of the space above the storage area S2a. The upper surfaces of the rear wall 12, the rear of the right side wall 13, and the rear of the left side wall 14 of the box body 10A are located at the same position in the vertical direction. The luggage board 20 is placed horizontally on the rear wall 12, the rear of the right side wall 13, and the rear of the left side wall 14, and the rear edge, right edge, and left edge of the luggage board 20 are supported from below by the box body 10A.

[0029] As shown in Figures 1, 2, and 8, the slide board 30 has a length in the vehicle width direction that corresponds to the vehicle width direction length of the luggage board 20. The slide board 30 is attached (fixed) to the rear seat 2 from the rear of the vehicle via a bracket 40 and slides integrally with the rear seat 2 on the luggage board 20 in the vehicle longitudinal direction. When the rear seat 2 is slid forward to expand the storage area S2a, the slide board 30 slides forward relative to the luggage board 20 and covers the expanded portion of the storage area S2a from above. In other words, the slide board 30 works in cooperation with the luggage board 20 to function as a lid for the storage area S2a and as the floor of the space above the storage area S2a.

[0030] In this embodiment, the slide board 30 has a right slide board 31 and a left slide board 32, which are separate from each other. The right slide board 31 is attached (fixed) to the right seat 21 and slides integrally with the right seat 21 in the vehicle's longitudinal direction. The left slide board 32 is attached (fixed) to the left seat 22 and slides integrally with the left seat 22 in the vehicle's longitudinal direction.

[0031] The right slide board 31 has a front portion 31a positioned along the rear surface of the seat back 21b of the right seat 21, a rear portion 31b placed on the right side of the luggage board 20, and a hinge portion 31c provided between the front portion 31a and the rear portion 31b and having a pivot axis extending in the vehicle width direction. The hinge portion 31c has, for example, two PP (polypropylene) hinges arranged in the front-rear direction. The two PP hinges each extend in the vehicle width direction across the entire width of the right slide board 31. The front portion 31a can follow the reclining (tilting and standing) of the seat back 21b by the front PP hinge (front portion 31a side). Figure 8 shows the front portion 31a rotated to a horizontal position. The rear portion 31b can be rotated vertically by the rear PP hinge (rear portion 31b side) to open and close the storage area S2a.

[0032] The left slide board 32 has a front portion 32a positioned along the rear surface of the seat back 22b of the left seat 22, a rear portion 32b placed on the left side of the luggage board 20, and a hinge portion 32c provided between the front portion 32a and the rear portion 32b and having a pivot axis extending in the vehicle width direction. The front portion 32a, the rear portion 32b, and the hinge portion 32c have the same structure as the front portion 31a, the rear portion 31b, and the hinge portion 31c, respectively.

[0033] As shown in Figures 2 and 8, the bracket 40 includes a right bracket 41 for attaching the right sliding wall 10B1 to the right seat 21, and a left bracket 42 for attaching the left sliding wall 10B2 to the left seat 22. The right bracket 41 and the left bracket 42 are members formed from sheet metal and have the same structure as each other, except that they are symmetrical. The right bracket 41 includes a front support portion 41a for supporting the right front wall 151, a mounting portion 41b for attaching to the right seat 21, and an intermediate support portion 41c for supporting the right intermediate wall 161.

[0034] The front support portion 41a is attached to the right front wall 151 from the front of the vehicle and fixed to the right front wall 151 by connecting members such as clips or bolts. As a result, the right sliding wall 10B1 is fixed to the right bracket 41. In the illustrated example, the front support portion 41a is rectangular in shape, having dimensions corresponding to the dimensions of the right front wall 151 when viewed from one side in the front-rear direction of the vehicle, and covers almost the entire right front wall 151 from the front of the vehicle. The upper right, upper left, lower right, and lower left of the right front wall 151 are connected (fixed) to the front support portion 41a by clips. With this front support portion 41a, the right front wall 151 is reinforced from the front of the vehicle, and deformation of the right front wall 151 is suppressed when the right front wall 151 is pushed forward by luggage or the like.

[0035] The mounting portion 41b is flange-shaped, extending in the vehicle width direction along the upper edge of the front support portion 41a and protruding forward from the upper edge. As shown in Figure 9, the mounting portion 41b is fixed to a pair of left and right stays 6, 6. The pair of stays 6, 6 are high-rigidity members that extend in the vehicle width direction and extend rearward and upward from the cross member 7 supported by the support frame 5. The slide board 30 is attached to the mounting portion 41b. The intermediate support portion 41c extends forward from the vehicle width direction inner edge of the front support portion 41a and is positioned adjacent to the vehicle width direction outer side of the right intermediate wall 161. The intermediate support portion 41c supports the right intermediate wall 161 when the right intermediate wall 161 is pushed outward (to the right) in the vehicle width direction by luggage or the like, thereby suppressing deformation of the right intermediate wall 161.

[0036] The left bracket 42 has a front support portion 42a that supports the left front wall 152, a mounting portion 42b that is attached to the left seat 22, and an intermediate support portion 42c that supports the left intermediate wall 162. Since the left bracket 42 has a structure that is symmetrical to the right bracket 41, a detailed explanation of the front support portion 42a, the mounting portion 42b, and the intermediate support portion 42c will be omitted.

[0037] As described above, the vehicle luggage compartment structure 1 according to this embodiment is provided with a luggage box 10 located in a luggage compartment S2 behind the rear seat 2 in the passenger compartment, with a storage area S2a formed inside. The luggage box 10 has a bottom wall 11 that extends in the longitudinal and width directions of the vehicle and defines the lower end of the storage area S2a, a rear wall 12 that extends upward from the rear edge of the bottom wall 11 and defines the rear end of the storage area S2a, and a front wall 15 that faces the rear wall 12 in the longitudinal direction of the vehicle and defines the front end of the storage area S2a. The rear seat 2 has seat portions 21a and 22a that are spaced apart above the floor portion 3 of the vehicle and are slidable in the longitudinal direction of the vehicle. Furthermore, the luggage box 10 is installed in the floor portion 3 of the cargo compartment S2 and comprises a box body 10A having a bottom wall 11 and a rear wall 12, and a sliding wall 10B that is attached to the rear seat 2 from the rear side of the vehicle and slides integrally with the rear seat 2 in the front-rear direction of the vehicle. The sliding wall 10B has a front wall 15, which extends downward from the rear of the seat portions 21a and 22a.

[0038] With this structure, when the rear seat 2 slides forward, the front wall 15 also slides forward with the rear seat 2, causing the front end of the storage area S2a to be displaced forward and expanding the storage area S2a forward. In this state, the entire area from the rear wall 12 provided at the rear edge of the bottom wall 11 to the front wall 15 attached to the rear of the seat portions 21a and 22a can be used as the storage area S2a in the longitudinal direction of the vehicle. Thus, according to this embodiment, the cargo area S2 behind the sliding rear seat 2 can be fully and effectively utilized as the storage area S2a. In addition, the front wall 15, which extends downward relative to the rear seat 2, separates the storage area S2a from the space below the rear seat 2 in the longitudinal direction of the vehicle. This prevents luggage from moving from the storage area S2a to the space below the rear seat 2.

[0039] Furthermore, in the vehicle cargo compartment structure 1 of this embodiment, the rear seat 2 has a right seat 21 and a left seat 22 that can slide independently of each other. The sliding wall 10B is separate from each other and has a right sliding wall 10B1 and a left sliding wall 10B2 that are attached to the right seat 21 and the left seat 22, respectively. The right sliding wall 10B1 has a right front wall 151 that constitutes the right part of the front wall 15, and the left sliding wall 10B2 has a left front wall 152 that constitutes the left part of the front wall 15. With this structure, the right front wall 151 and the left front wall 152 can be slid independently of each other so that they follow the right seat 21 and the left seat 22, respectively.

[0040] Furthermore, the right sliding wall 10B1 has a right intermediate wall 161 extending forward from the inner edge in the vehicle width direction of the right front wall 151, and the left sliding wall 10B2 has a left intermediate wall 162 extending forward from the inner edge in the vehicle width direction of the left front wall 152. With this structure, when the right seat 21 and the left seat 22 are positioned offset from each other, the right intermediate wall 161 or the left intermediate wall 162 can prevent luggage from passing through the space between the right front wall 151 and the left front wall 152, which are positioned offset in the longitudinal direction of the vehicle, and leaving the storage area S2a.

[0041] Furthermore, in the vehicle luggage compartment structure 1 of this embodiment, the tool storage section 18 of the box body 10A is located below the storage area S2a. With this arrangement of the tool storage section 18, a storage area S2a that is wider in the vehicle width direction and shallower in the vertical direction is formed within the luggage box 10 compared to the case where tool storage sections are provided on the right and left sides of the storage area. When tool storage sections are provided on the right and left sides of the storage area, the storage area becomes narrower and deeper in the vehicle width direction, and its uses become relatively limited. In contrast, according to this embodiment, a storage area S2a that is wide and shallow in the vehicle width direction and has high versatility can be provided.

[0042] Furthermore, the luggage box 10 of this embodiment can be installed in the lower part of the cargo compartment S2 without requiring major design changes to the surrounding parts of the luggage box 10 (for example, the quarter trim and tail end trim). Therefore, the vehicle cargo compartment structure 1 of this embodiment can be applied inexpensively to vehicles with conventional designs.

[0043] As shown in Figures 4 to 6, in this embodiment, the sliding wall 10B further has inner walls (171, 172) that extend from the outer edge in the vehicle width direction of the front wall 15 toward the rear of the vehicle and are positioned adjacent to the inner side in the vehicle width direction of the side walls (13, 14) of the box body 10A. Specifically, the right sliding wall 10B1 has a right inner wall 171 that extends from the outer edge (right edge) in the vehicle width direction of the right front wall 151 toward the rear of the vehicle and is positioned adjacent to the inner side (left side) in the vehicle width direction of the right side wall 13. The left sliding wall 10B2 has a left inner wall 172 that extends from the outer edge (left edge) in the vehicle width direction of the left front wall 152 toward the rear of the vehicle and is positioned adjacent to the inner side (right side) in the vehicle width direction of the left side wall 14.

[0044] The right inner wall 171 and the left inner wall 172 are generally rectangular in shape when viewed from one side in the vehicle width direction, and extend in the vehicle's longitudinal and vertical directions. The right inner wall 171 extends vertically from near the lower edge to near the upper edge of the rear of the right side wall 13. The left inner wall 172 extends vertically from near the lower edge to near the upper edge of the rear of the left side wall 14. When the right seat 21 is positioned at the rearmost position, the right inner wall 171 overlaps with the rear of the right side wall 13 in the vehicle width direction. When the left seat 22 is positioned at the rearmost position, the right inner wall 171 overlaps with the rear of the left side wall 14 in the vehicle width direction. In this embodiment, the right side wall 13 and the left side wall 14 each correspond to the "outer wall" according to the present invention, and the right inner wall 171 and the left inner wall 172 each correspond to the "inner wall" according to the present invention.

[0045] With this structure, as shown in Figure 10, when the right seat 21 slides forward, the right inner wall 171 slides forward relative to the right wall 13 and is positioned adjacent to the front of the right wall 13 on the inside in the vehicle width direction. This prevents luggage from falling out of the storage area S2a beyond the lower front of the right wall 13. Similarly, when the left seat 22 slides forward, the left inner wall 172 slides forward relative to the left wall 14 and is positioned adjacent to the front of the left wall 14 on the inside in the vehicle width direction. This prevents luggage from falling out of the storage area S2a beyond the lower front of the left wall 14.

[0046] As shown in Figures 4 to 10, in this embodiment, in order to prevent the lower ends of the sliding walls 10B (10B1, 10B2) from rubbing against the luggage carpet 19, the sliding walls 10B (10B1, 10B2) are positioned with a gap above the upper surface of the luggage carpet 19. The sliding wall 10B further has a sealing member 50 that protrudes downward from the lower end of the front wall 15 and is made of an elastic material such as foamed rubber or sponge. It is preferable that the sealing member 50 is provided over the entire width of the front wall 15. In the illustrated example, elongated sealing members 50 extending in the vehicle width direction are attached from the front of the vehicle to the lower edges of the right front wall 151 and the left front wall 152, respectively (see Figure 8). The sealing member 50 lightly contacts the luggage carpet 19 from above and may slide on the luggage carpet 19 when sliding, or it may float slightly above the luggage carpet 19.

[0047] With this structure, the gap between the lower end surface of the front wall 15 (151, 152) and the upper surface of the luggage carpet 19 is sealed by the sealing member 50, thereby preventing small items from passing through the gap and preventing items or the user's fingers from getting caught in the gap. Furthermore, the soft sealing member 50, which is made of an elastic material, elastically deforms when items or fingers come into contact with the sealing member 50. This protects items and fingers.

[0048] The sealing member 50 may also be provided on the lower edges of the intermediate walls 161, 162 and the inner walls 171, 172, so as to protrude downward from their respective lower ends. In the illustrated example, a sealing member 50 is provided on the lower edge of the right slide wall 10B1, extending continuously from the rear end of the right inner wall 171, through the right front wall 151, to the right intermediate wall 161. Similarly, a sealing member 50 is provided on the lower edge of the left slide wall 10B2, extending continuously from the rear end of the left inner wall 172, through the left front wall 152, to the left intermediate wall 162. With such a structure, it is possible to more reliably prevent luggage or other items from getting caught in the gap between the slide wall 10B and the luggage carpet 19.

[0049] As shown in Figures 4 to 9, in this embodiment, the sliding wall 10B is provided on the lower edge of the front wall 15 and has flange portions 15a (151a, 152a) that protrude toward the rear of the vehicle. The flange portions 15a extend in the vehicle width direction across the entire width of the lower edge of the front wall 15. In this embodiment, the flange portions 15a include a right flange portion 151a provided on the lower edge of the right front wall 151 and a left flange portion 152a provided on the lower edge of the left front wall 152. By providing such flange portions 15a (151a, 152a), the rigidity of the front wall 15 (151, 152) in the front-rear direction is increased, and luggage and other items can be more reliably prevented from entering the gap between the lower end surface of the front wall 15 (151, 152) and the upper surface of the luggage carpet 19.

[0050] In the illustrated example, the sliding wall 10B further includes a flange portion 171a provided on the lower edge of the right inner wall 171 and projecting inward (to the left) in the vehicle width direction, and a flange portion 171a provided on the lower edge of the left inner wall 172 and projecting inward (to the right) in the vehicle width direction (see Figure 6). The provision of such flange portions 171a and 172a increases the rigidity of each inner wall 171 and 172 in the vehicle width direction.

[0051] The upper surface of the flange portion 15a shown in Figures 4 to 9 is a horizontal plane parallel or substantially parallel to the vehicle's longitudinal direction. Alternatively, as shown in Figure 11, the upper surface of the flange portion 15a (151a, 152a) may be an inclined surface that slopes downward as it approaches the rear of the vehicle. As mentioned above, since the sliding wall 10B is positioned above the luggage carpet 19, it is undesirable for a downward load to act on the sliding wall 10B. By having an inclined surface on the upper surface of the flange portion 15a (151a, 152a), when luggage is placed on the flange portion 15a (151a, 152a), part of the luggage rests on the luggage carpet 19, and part of the load of the luggage is distributed to the luggage carpet 19. This reduces the downward load acting on the sliding wall 10B (10B1, 10B2).

[0052] In the example shown in Figure 11, the upper surface of the flange portion 171a of the right inner wall 171 is also an inclined surface that slopes downward as it is directed inward (to the left) in the vehicle width direction. Similarly to the flange portion 171a, the upper surface of the flange portion 172a of the left inner wall 172 may also be an inclined surface that slopes downward as it is directed inward (to the right) in the vehicle width direction. With such a structure, the downward load acting on the sliding wall 10B (10B1, 10B2) when a load is placed on the flange portions 171a, 172a can be reduced.

[0053] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and further modifications and changes are possible based on the technical concept of the present invention.

[0054] For example, in the above embodiment, the rear seat 2 includes a right seat 21 and a left seat 22 that can slide independently of each other, but instead, the rear seat 2 may be a single unit. In this case, instead of two seat portions 21a and 22a, the rear seat 2 has a single seat portion that extends in the vehicle width direction over approximately the entire width of the passenger compartment S1. The sliding wall 10B is formed from a single member having a length in the vehicle width direction corresponding to the length of the bottom wall 11 in the vehicle width direction. Specifically, the sliding wall 10B has a front wall 15 consisting of a single wall having a length in the vehicle width direction corresponding to the length of the bottom wall 11 in the vehicle width direction, and a right inner wall 171 and a left inner wall 172 extending towards the rear of the vehicle from both outer edges (right edge and left edge) in the vehicle width direction of the front wall 15, and does not have intermediate walls 161 and 162. The sliding board 30 is formed from a single board having a length in the vehicle width direction corresponding to the length of the luggage board 20 in the vehicle width direction.

[0055] In the above-described embodiment, a luggage board 20 is provided on top of the luggage box 10, but the luggage board 20 is not necessarily required. If the luggage board 20 is not provided, the rear wall 12, right side wall 13, and left side wall 14 of the luggage box 10 do not need to have high rigidity to support the luggage board 20, so each wall 12, 13, and 14 can be made thinner to expand the storage area S2a in the vehicle's longitudinal and vehicle width directions. In this case, the slide board 30 is also not required. [Explanation of symbols]
