The vehicle luggage compartment structure described in Patent Document 1 has a structure in which the position of a single board member can be swapped between a bottom position and a position above it, and this swapping can be easily performed. In addition, the vehicle luggage compartment structure described in Patent Document 2 has a structure in which the front seat back of the luggage compartment is folded forward to form a large space, making it easy to carry heavy objects, luggage with wheels, and the like into this space. In addition to these, various forms of vehicle luggage compartment structures are required depending on user needs. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4111178 [Patent Document 2] Patent No. 5209995 [Patent Document 3] JP 2015-166231 A Summary of the Invention [Problem to be solved by the invention]

[0004] In vehicles in which the seatbacks of seats located at the front of the luggage compartment can be folded forward to make the backs approximately horizontal, the floor surface of the luggage compartment may be formed at a height lower than the backs of the folded-down seatbacks in order to ensure the capacity of the luggage compartment. However, some users may place importance on ensuring a large, flat space, as in the vehicle described in Patent Document 3.

[0005] The present invention was made in consideration of such circumstances, and its objective is to provide a vehicle luggage compartment structure that can form a flat space in a vehicle with a large luggage compartment, and also to provide a second deck construction set for a vehicle for forming such a vehicle luggage compartment structure. [Means for solving the problem]

[0006] In order to solve the above problems, the vehicle luggage compartment structure of the present invention comprises: a first deck board provided behind a seat back that can be folded forward until the back surface thereof is substantially horizontal, and installed at a height lower than the back surface of the seat back when folded forward; a second deck board that can be installed in a position overlapping above the first deck board and at the same height as the back of the seat back when folded forward; The present invention is characterized by the following features.

[0007] With this vehicle luggage compartment structure, even in a vehicle where the top surface of the first deck board is lower than the back of the seatback, by installing a second deck board, the seatback and second deck board can form a relatively large, flat space inside the vehicle cabin, improving the flexibility of use of the vehicle cabin.In addition, with this vehicle luggage compartment structure, by installing two-tiered deck boards, the interior of the luggage compartment can be roughly divided into two levels, improving the flexibility of storage.

[0008] In the above configuration, the first deck board may be configured to be housed inside the second deck board in the vehicle width direction when viewed from above.

[0009] With this vehicle luggage compartment structure, the first deck board can be raised or removed from an opening formed when the second deck board is raised or removed starting from the front, making it possible to effectively use the space below the first deck board.

[0010] The above configuration can include a front support that is held against left and right side wall portions inside the vehicle cabin in a position extending in the vehicle width direction and supports the front side of the second deck board, a rear support that is arranged behind the front support in a position extending in the vehicle width direction and supports the rear side of the second deck board, and a pair of holding members that are installed on a floor surface facing upward and located on each of the left and right sides of the first deck board and hold both end portions of the rear support.

[0011] This vehicle luggage compartment structure embodies a configuration for supporting the second deck board, and can easily construct a second deck that is connected to the seat back and flat with the seat back. Also, because no members for supporting the second deck board are installed on top of the first deck board, lifting the second deck board also makes it possible to lift or remove the first deck board, making it possible to effectively utilize the space below the first deck board.

[0012] In the above configuration, the vehicle luggage compartment structure can be configured such that each of the left and right side wall portions has a bulging portion that bulges toward the interior of the vehicle compartment so as to cover a wheel house of the vehicle, the front support body is disposed between the bulging portions of each of the left and right side wall portions, and each of the pair of retaining members fills the space on the left and right sides of the second deck board rearward of the bulging portion and has an upper surface that is flush with the upper surface of the second deck board.

[0013] In this vehicle luggage compartment structure, the upper surfaces of the pair of retaining members are also flush with the upper surface of the second deck board, expanding the flat space and making it possible to effectively utilize the space on the second deck.

[0014] The above configuration can include a front support body that is held against left and right side wall portions inside the vehicle cabin in a position extending in the vehicle width direction and supports the front side of the second deck board, and the front support body can have a free-standing support structure for supporting the rear side of the second deck board in an upright position with the rear side raised.

[0015] In this vehicle luggage compartment structure, the second deck board can be raised without the need for a person to support it, making it easy to load and unload luggage into the space below the second deck board.

[0016] In the above configuration, the second deck board has a shape in which the dimension in the vehicle width direction decreases toward the front of the front end, and each of the left and right sides of the front end is an inclined portion, the front support body includes a longitudinal front support column member on which the second deck board is placed, and a pair of front brackets fixed to both end portions of the front support column member and for attachment to the left and right side wall portions, each of the pair of front brackets has a fitting groove that opens upward and into which the inclined portion of the second deck board fits; The free-standing support structure can be configured to support the second deck board in the upright position by fitting the front end of the second deck board below the front support member and fitting each of the inclined portions into the fitting grooves of the pair of front brackets.

[0017] The vehicle luggage compartment structure of this configuration embodies a structure that supports the second deck board in an upright position, and is capable of supporting the second deck board in an upright position with a simple structure.

[0018] The above configuration can include a rear support body that is arranged in a position extending in the vehicle width direction and supports the rear side of the second deck board, and a pair of retaining members that are located on the left and right sides of the first deck board and installed on the floor surface facing upward and that retain both ends of the rear support body, and the pair of retaining members can be configured to have tonneau cover receiving portions that engage both ends of a retractable tonneau cover that is mounted on the vehicle.

[0019] With this vehicle luggage compartment structure, the tonneau cover, which could not be stored within the first deck board, can be stored between the first and second deck boards, making it possible to effectively utilize the space formed on the second deck board together with the seat backs.

[0020] In the above-described configuration, the tonneau cover storage portion may be formed in the shape of a groove that opens to the interior of the vehicle and extends vertically with the same width.

[0021] Many tonneau covers have a configuration in which both ends can be attached by being tensioned outward using elastic members, and a vehicle luggage compartment structure with this configuration allows the tonneau cover to be stored at a different height. In other words, even if luggage is placed in the luggage compartment, the tonneau cover can be stored above the luggage. Depending on the vehicle specifications, even if the deck side trim forming the side walls of the luggage compartment is made of the same material, the height of the first deck board may differ due to differences in the materials forming the floor, i.e., the height of the first deck board may differ relative to the deck side trim. Even in such cases, a vehicle luggage compartment structure with this configuration allows the tonneau cover to be stored.

[0022] In the above configuration, the vehicle may further include a rear support body that is disposed in a position extending in the vehicle width direction and supports the rear side of the second deck board, and a pair of holding members that are located on each of the left and right sides of the first deck board and are installed on a floor surface that faces upward and that holds both ends of the rear support body, The rear support body can be configured to include a longitudinal rear support member on which the second deck board is placed, and a pair of rear brackets fixed to both end portions of the rear support member for engaging with each of the pair of retaining members, and can be configured to be attachable to and detachable from the pair of retaining members.

[0023] With this vehicle luggage compartment structure, not only the second deck board but also the rear support body can be removed, making it easy to open and close the first deck board and to load and unload luggage into the storage space below the first deck board.

[0024] In the above configuration, the vehicle luggage compartment structure includes a rear partition member that is erected at the rear of the luggage compartment to separate the rear end of the luggage compartment, the rear partition member having an upper end that is lower in height than the second deck board, and each of the pair of rear side brackets having an abutment portion that extends above the rear partition member and abuts against the rear partition member from above.

[0025] In a vehicle luggage compartment structure configured as described above, even if a large force is applied to the rear portion of the second deck board, the second deck board is also supported by the rear partition member via the rear support body, so even if the rear support body is detachable, the second deck board can be firmly supported.

[0026] In the above configuration, each of the pair of retaining members can be configured so that its upper surface is flush with the upper surface of the second deck board, and each of the pair of rear brackets can be configured so that its upper surface is flush with the upper surfaces of the pair of retaining members.

[0027] In this vehicle luggage compartment structure, the seat back, the second deck board, the pair of retaining members, and the pair of rear brackets are all flat, ensuring a large flat space.

[0028] In the above configuration, a rear support body is provided which is disposed in a position extending in the vehicle width direction and which supports a rear side of the second deck board in a placed state, the second deck board has a curved portion at its rear end that bulges rearward, and is supported by the rear support body with the curved portion protruding rearward from the rear support body, The rear support body may be provided with a curved portion support portion at the center in the vehicle width direction, the curved portion support portion extending rearward to support the curved portion of the second deck board.

[0029] The luggage compartment is often accessed from the rear of the vehicle, and the rear end of the second deck board is prone to being subjected to force from above. This vehicle luggage compartment structure can adequately support the force applied to the rear end of the second deck board while maintaining the design of the second deck board.

[0030] In order to solve the above problems, the second deck construction set for a vehicle of the present invention comprises: A second deck construction set for a vehicle is provided in a luggage compartment of a vehicle having a first deck mainly composed of a first deck board that is provided behind a seat back that can be folded forward until the back surface of the seat back is approximately horizontal and is installed at a height lower than the back surface of the seat back when folded forward, for constructing a second deck above the first deck at a height position that is the same as the back surface of the seat back when folded forward, A second deck board; a front support body that is held against left and right side wall portions inside the vehicle cabin in a position extending in the vehicle width direction and supports a front side of the second deck board; a rear support body disposed rearward of the front support body and extending in the vehicle width direction, and supporting a rear side of the second deck board; a pair of holding members that are located on the left and right sides of the first deck board and are installed on an upward-facing floor surface, and that hold both ends of the rear support body; The present invention is characterized in that it comprises:

[0031] This second deck construction set for vehicles can easily construct a second deck that is flat with the back of the seat back for vehicles with a luggage compartment where the height of the first deck is lower than the back of the seat back when folded forward. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0034] Hereinafter, as a mode for carrying out the present invention, examples of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following examples, and can be carried out in various forms with various modifications and improvements based on the knowledge of those skilled in the art.

[0035] FIGS. 1 to 5 show a vehicle employing a vehicle luggage compartment structure according to an embodiment of the present invention. FIGS. 2, 4, and 5 are views showing the luggage compartment and surrounding area of ​​the vehicle 10 from a diagonally rearward perspective. Also, FIGS. 2 to 5 omit the illustration of a back door provided at the rear of the luggage compartment that can be opened and closed, and the deck side trim that forms the left side wall of the luggage compartment. Instead, the interior materials constituting the luggage compartment of the vehicle 10 are shown, including the deck side trim 12 that forms the right side wall of the luggage compartment, a finish plate (rear partition member) 13 that forms the rear end of the luggage compartment, and a trunk box 14 installed on the bottom of the luggage compartment. The vehicle 10 is equipped with a second seat 16, and the seatback 17 of the second seat 16 can be folded forward so that the back surface 17a of the seatback 17 is in a substantially horizontal position. In other words, the vehicle 10 allows the space behind the driver's seat and passenger seat, including the space above the second seat 16, to function as a luggage compartment.

[0036] As shown in Fig. 5, the vehicle luggage compartment structure of this embodiment includes a generally rectangular first deck board 18 that can be placed on top of a trunk box 14 that has multiple storage spaces. In the specifications shown in Fig. 5, vehicle 10 is configured so that upper surface 18a of first deck board 18 is placed at a position lower than the height of back surface 17a of seat back 17 of second seat 16, as also shown in Fig. 3, in order to ensure a large luggage compartment.

[0037] On the other hand, there is also a demand for a large, flat space within the vehicle cabin. To meet such demands, the vehicle 10 is capable of being fitted with a second vehicle deck construction set 20, which is an embodiment of the present invention, and by installing the second vehicle deck construction set 20, a vehicle luggage compartment structure according to the embodiment of the present invention is realized. In other words, in addition to the first deck on the first deck board 18 shown in Fig. 5, the vehicle 10 can be fitted with a second deck using the second vehicle deck construction set 20, as shown in Figs. 1 to 4. The second vehicle deck construction set 20 will be described in detail below.

[0038] This second deck construction set 20 for a vehicle (hereinafter sometimes simply referred to as the "deck construction set 20") is comprised of a second deck board 22, a front support 24 that supports the front side of the second deck board 22, a rear support 26 that supports the rear side of the second deck board 22, and a pair of side boards (holding members) 28 that hold the rear support 26. In this deck construction set 20, the second deck is constructed by installing the pair of side boards 28, the front support 24, the rear support 26, and the second deck board 22 in this order. Below, the features and functions of each component will be explained in detail in that order.

[0039] First, the pair of side boards 28 are placed on the deck side trim 12. More specifically, as shown in Fig. 5, each of the left and right deck side trims 12 has not only side wall portions 12a of the luggage compartment, but also floor surfaces 12b formed on the left and right sides of the first deck board 18 that are flush with the upper surface 18a of the first deck board 18, and the side boards 28 are placed on these floor surfaces 12b. Note that the side wall portions 12a of the deck side trim 12 have bulging portions 12c that bulge out toward the interior of the vehicle so as to cover the wheel houses of the vehicle 10, and a space that extends in the vehicle width direction exists behind the bulging portions 12c, and the floor surfaces 12a form the floor surface of this space. The sideboard 28 is a member that raises the floor surface, and as shown in Figures 1 to 4, 6 and 7, the outer shape of the upper surface 30 facing outside the passenger compartment is formed to match the inner shape of the deck side trim 12, and is placed in contact with the deck side trim 12 with no gaps between them.

[0040] Furthermore, the side board 28 is placed so that the outer edge 32 of its bottom surface facing the interior of the vehicle is located further outward than the outer edge of the floor surface 12b facing the interior of the vehicle, and does not protrude from the floor surface 12b of the deck side trim 12. Meanwhile, the outer edge 30a of its top surface 30 facing the interior of the vehicle protrudes further toward the interior of the vehicle than the outer edge 32 of its bottom surface facing the interior of the vehicle, and is located at approximately the same position (slightly outward) in the vehicle width direction as the outer edge of the floor surface 12b of the deck side trim 12, as shown in Figure 7. When the second deck board 22 is placed on it, the outer edge 30a of the top surface 30 facing the interior of the vehicle comes into contact with the outer edge of the second deck board 22 in the vehicle width direction, as shown in Figures 1 and 3, to prevent the second deck board 22 from shifting in the vehicle width direction.

[0041] 6 and 8, sideboard 28 has a wall surface portion 34 on the interior side of the vehicle compartment that is shaped like a hollow between multiple pillars 34a, thereby expanding the space above first deck board 18 in the vehicle width direction. Also, as shown in Fig. 8, the hollowed-out shape is used to form multiple ribs 36 on the back surface of sideboard 28, ensuring sufficient rigidity.

[0042] Next, the front support body 24 will be described. As shown in FIGS. 9 to 11, the front support body 24 is configured to include a longitudinal front reinforcement (front support member) 40 extending in the vehicle width direction, and a pair of front brackets (front brackets) 42 fixed to both end portions of the front reinforcement 40. As shown in FIG. 11, the pair of front brackets 42 are made up of a metal bracket main body 44 and a resin bracket cover 45 that covers the bracket main body 44. The pair of front brackets 42 are attached to the left and right deck side trims 12, respectively. Specifically, as shown in FIG. 5, the bulging portion 12c is provided with an attachment portion 12d for attaching a hook for hanging luggage in the luggage compartment, and the front bracket 42 is fixed to the deck side trim 12 using the attachment portion 12d. More specifically, the bracket body 44 of each of the left and right front brackets 42 is fastened to the mounting portion 12d with a bolt 46, and the front reinforcement 40 is placed on top of the bracket bodies 44 and fixed with a bolt and nut 47. Then, a bracket cover 45 is placed over the end of the front reinforcement 40 and the bracket body 44 from above and fixed with a clip 48.

[0043] The bracket cover 45 has a claw portion that protrudes downward from the rearward extending portion, and the claw portion is configured to fit into a fitting hole 28a formed in the sideboard 28. With this configuration, the front support body 24 fixes the front end of the sideboard 28 that is simply placed on the floor surface 12b.

[0044] The front support body 24 is fixed to the deck side trim 12 with the structure described above, and can firmly support the second deck board 22 placed on it. As shown in FIGS. 9 to 11, the bracket cover 45 has a shape that includes a standing wall portion 45a that extends in the front-to-rear direction along the outer edge of the outer side of the vehicle compartment, and a protruding portion 45b that is triangular in plan view. Meanwhile, as shown in FIG. 1 and other figures, the second deck board 22 has a shape in which the vehicle width direction dimension decreases toward the front of the front end, and each of the left and right ends of the front end forms an inclined portion 22a that is inclined relative to the front-to-rear direction. As a result, when the second deck board 22 is placed on the front support body 24, as shown in FIG. 12, the inclined portion 22a comes into contact with the protruding portion of the bracket cover 45, and the outer edge of the second deck board 22 in the vehicle width direction that continues from the inclined portion 22a comes into contact with the standing wall portion 45a. Therefore, front support bodies 24 can support placed second deck board 22 in a state that prevents it from shifting forward and in the vehicle width direction. The height of protrusions 45b is set to be approximately equal to the thickness of second deck board 22, and the upper surface of second deck board 22 and the upper surface of protrusions 45b are flush with each other.

[0045] As shown in FIGS. 4 and 13 , the front support 24 can support the second deck board 22 in an upright position, specifically, in which the rear side of the second deck board 22 is raised. In other words, the front support 24 can be considered to have a free-standing support structure. This free-standing support structure utilizes the aforementioned shape of the front end of the second deck board 22, which narrows toward the front. Specifically, as shown in FIGS. 9 to 11 , the bracket cover 45 is formed with a fitting groove 45c that extends generally in the vehicle width direction and opens upward and toward the interior of the vehicle compartment. The bottom of the fitting groove 45c is inclined downward toward the interior of the vehicle compartment, and the depth direction is inclined toward the front as it approaches the bottom. In other words, by inserting the front end of the second deck board 22 downward and forward into the fitting groove 45c, the inclined portion 22a of the second deck board 22 abuts against the bottom surface of the fitting groove 45c. In this state, the front end of second deck board 22, where the width is reduced, fits under front reinforcement 40. Then, when the user releases second deck board 22, as shown in Figure 14, the upper surface of second deck board 22 abuts against front reinforcement 40 and the lower surface abuts against the surface of fitting groove 45c on the rear side of the vehicle, so that second deck board 22 is supported in an upright position.

[0046] Next, the rear support body 26 will be described. As shown in FIGS. 15 and 16 , the rear support body 26 is configured to include a longitudinal rear reinforcement (rear support member) 50 extending in the vehicle width direction, and a pair of rear brackets (rear brackets) 52 fixed to both ends of the rear reinforcement 50. The rear support body 26 can be placed on the pair of side boards 28 shown in FIGS. 6 and 7 such that each of the pair of rear brackets 52 fits into a recess 28b formed on the rear side of each of the pair of side boards 28. When the rear support body 26 is placed on the pair of side boards 28, the upper surface of the rear bracket 52 is flush with the upper surface 30 of the side board 28. Meanwhile, the rear reinforcement 50 is fixed to the rear bracket 52 at a position such that its upper surface is lower than the upper surface of the rear bracket 52 by the thickness of the second deck board 22. In other words, when second deck board 22 is placed, the upper surface of second deck board 22 is flush with the upper surface of rear bracket 52 and upper surface 30 of side board 28, forming a flat space across almost the entire luggage compartment, as shown in Figures 2 and 3. Rear bracket 52 is configured to simply be placed in recess 28b of side board 28, and rear support body 26 can be easily attached and detached, as shown in Figure 17.

[0047] 1 and 2, second deck board 22 has curved portion 22b that bulges rearward at its rear end to match the shape of finish plate 13. However, because rear reinforcement 50 is straight, curved portion 22b at the rear end of second deck board 22 protrudes rearward from rear reinforcement 50. Therefore, if a force is applied from above to curved portion 22b, there is a risk that the front side of second deck board 22, which is simply placed on top, will rise up with rear reinforcement 50 as a fulcrum as the curved portion lowers, causing the second deck board 22 to become dislodged. In contrast, in this embodiment, as shown in FIGS. 1 and 15 to 17, rear reinforcement 50 is provided with striker (curved portion support portion) 54 that protrudes rearward in the center in the vehicle width direction, which can resist a force applied from above to curved portion 22b and prevent rattling of second deck board 22. Incidentally, the second deck board 22 has a symmetrical shape and can be placed upside down, with the back side remaining made of a resin base material while the front side has carpet material attached.

[0048] Furthermore, in this embodiment, rear support bodies 26 are configured to be able to firmly support a force applied from above to the rear portion of second deck board 22. Specifically, as shown in Figures 15 and 16, rear bracket 52 has protruding portion 52a that protrudes rearward, and when rear support bodies 26 are placed on side board 28, protruding portion 52a extends to a position where it vertically overlaps finish plate 13 and functions as an abutment portion that abuts finish plate 13 from above. Therefore, upward force applied to second deck board 22 is distributed to side board 28 and finish plate 13 via rear support bodies 26, and the vehicle luggage compartment structure of this embodiment can firmly support second deck board 22.

[0049] As described above, by installing the deck construction set 20 of this embodiment, a luggage compartment structure is realized in which the second deck board 22, which is at the same height as the back surface 17a of the seat back 17, is installed above the first deck board 18, which is located lower than the back surface 17a of the seat back 17 when the seat back 17 is folded forward. In other words, the vehicle luggage compartment structure of the present invention is realized. This makes it possible to form a relatively large, flat space within the vehicle cabin by the second deck, which is mainly composed of the second deck board 22 and above the back surface 17a of the seat back 17. Note that the deck construction set 20 of this embodiment allows the second deck to be constructed without any modification to the original vehicle luggage compartment structure shown in FIG. 5. Furthermore, the vehicle luggage compartment structure of this embodiment has not only a storage space below the first deck board 18, but also a storage space formed between the first deck board 18 and the second deck board 22. In other words, the storage space is divided into two levels, allowing for a high degree of storage flexibility.

[0050] Next, other functions of the vehicle luggage compartment structure of this embodiment, which are realized by the second deck construction set 20 for the vehicle, will be described. As previously mentioned, in this vehicle luggage compartment structure, none of the components of the second deck construction set 20 are placed on the first deck board 18. Furthermore, as shown in Figures 7 and 17, the dimension of the first deck board 18 in the vehicle width direction is slightly smaller than the distance between the pair of side boards 28. In other words, the dimension of the first deck board 18 in the vehicle width direction is approximately the same as that of the second deck board 22, and the first deck board 18 is configured to fit inside the second deck board 22 in the vehicle width direction in a top view. Furthermore, because the rear support body 26 is easily detachable, removing the rear support body 26 makes it possible to raise or remove the first deck board 18 from its front end as a starting point, as shown in Figures 18 and 19. Therefore, even if second deck board 22 is located above first deck board 18, the storage space below first deck board 18 can be effectively utilized.

[0051] The vehicle 10 of this embodiment is also equipped with a tonneau cover device 60 for covering the upper portion of the luggage compartment. The tonneau cover device 60 is a retractable tonneau cover device comprising a flexible, sheet-like tonneau cover body 62 and a retracting section 64 consisting of a shaft for retracting the tonneau cover body 62 and a case for accommodating the shaft. While the tonneau cover device 60 is not shown in use, Figure 3 and other figures show an attachment recess 66 for attaching the retracting section 64 of the tonneau cover device 60 and an engagement groove 68 for engaging the rear end of the extended tonneau cover body 62. Note that no space is provided below the first deck board 18 for storing the tonneau cover device 60. In this vehicle luggage compartment structure, the second vehicle deck construction set 20 can accommodate the tonneau cover device 60.

[0052] Specifically, as shown in FIGS. 20-22, each of the pair of sideboards 28 is provided with a tonneau cover storage compartment 70 that stores both ends of the tonneau cover device 60. As shown in FIGS. 21 and 22, the tonneau cover storage compartment 70 is formed as a groove that opens toward the interior of the vehicle and extends vertically. The upper portion of the tonneau cover storage compartment 70 is continuous with the recess 28b and also opens upward. The lower portion of the tonneau cover storage compartment 70 extends almost to the bottom end of the sideboard 28. Each end of the winding section 64 is biased outward in the longitudinal direction by an elastic member, allowing the tonneau cover device 60 to be held in a longitudinally stretched state. Therefore, the tonneau cover device 60 is inserted from above into the tonneau cover storage compartment 70 of each of the pair of sideboards 28 while extending in the vehicle width direction, and can be stored with both ends biased outward. Therefore, the tonneau cover device 60 can be stored at any vertical height. In other words, as shown in Figure 22, the tonneau cover device 60 can be stored not only when placed on the first deck board 18, but also, as shown in Figure 23, it can be stored above luggage 72 when the luggage 72 is stored on the first deck board 18.

[0053] Furthermore, in the vehicle 10 of this embodiment, the height at which the first deck board 18 is installed relative to the deck side trim 12 varies depending on the vehicle specifications, resulting in the height positions shown in Figures 24 and 25. As mentioned above, the second deck construction set 20 for a vehicle is installed relative to a pair of deck side trims 12, so it can be installed in the same way even if there are differences in specifications as described above. Furthermore, because the tonneau cover storage section 70 is formed in the shape of a groove extending in the vertical direction, it can store the tonneau cover device 60, as shown in Figures 24 and 25, regardless of the specifications.
