Description

[Technical field]

[0001] The present invention relates to a vehicle side structure. [Background technology]

[0002] For example, there is known a vehicle having a passenger compartment in which seats for passengers are arranged, and a luggage compartment arranged behind the passenger compartment. A deck board is usually arranged in the luggage compartment. For example, a deck board arranged in the luggage compartment has a structure as disclosed in Patent Document 1.

[0003] In the structure of the above example, side members such as interior members are arranged on both sides of the luggage compartment in the vehicle width direction. The side members are provided with support parts that protrude into the vehicle cabin and extend in the front-rear direction of the vehicle. The sides of the deck board are placed on the support parts. In addition, the front part of the deck board can abut against the back of the seat, and the rear part of the deck board abuts against the lower part of the back door opening. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2021-54255 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above example structure, the deck board is placed on supports provided on the side members, so the vertical movement of the deck board is not restricted. Also, because the front part of the deck board abuts against the seat, there is a possibility that the deck board may move in such a way that it presses against the back surface of the seat.

[0006] In addition, in a vehicle having the above-mentioned luggage compartment structure, when an impact load is applied due to a rear-end collision or the like, the side of the vehicle body may be deformed outward. For example, when an impact load is applied to the rear of the vehicle from behind, a member disposed in the rear of the vehicle may be deformed toward the inside of the vehicle cabin (the front side of the vehicle). In this case, in accordance with the deformation of the member, for example, a side body outer panel or the like disposed in the side of the vehicle may be deformed toward the outside of the vehicle (outside in the vehicle width direction).

[0007] When the side body outer panel or the like is deformed outward in the vehicle width direction, the inner panel, the side members, and other interior members may also be deformed outward in the vehicle width direction due to the deformation. In such a case, it may become impossible to maintain the state in which the deck board is placed on the support portion of the side member. Therefore, in the structure of the above example, there is room for improvement in terms of stably supporting the deck board on the side of the luggage compartment.

[0008] The present invention has been made to solve the above-mentioned problems, and its object is to provide a vehicle side structure that can more stably support a deck board placed in the luggage compartment of a vehicle. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the vehicle side structure of the present invention has a body structure that is arranged on the side of the vehicle and constitutes a vehicle side, and a deck board that is arranged transversely on the vehicle inside side of the body structure, the vehicle side structure having a bracket that is joined to the vehicle inside side of the body structure and supports the deck board, the bracket having a joint that faces the outside of the vehicle and is joined to the vehicle inside part of the body structure, and a flat surface that faces upwardly of the vehicle, and the deck board is fixed to the flat surface by a fixing member. Effect of the Invention

[0010] According to the present invention, it is possible to more stably support a deck board arranged in a luggage compartment of a vehicle. [Brief description of the drawings]

[0012] Hereinafter, an embodiment of a vehicle side structure according to the present invention will be described with reference to the drawings (FIGS. 1 to 8). In the drawings, the direction of the arrow Fr indicates the front in the vehicle longitudinal direction. In the description of the embodiment, the "front (front end) and rear (rear end)" correspond to the front and rear in the vehicle longitudinal direction. Additionally, the arrows R and L indicate the right and left sides when an occupant looks forward of the vehicle. Additionally, the arrow U indicates the upward direction in the vehicle vertical direction.

[0013] The vehicle side structure of this embodiment is a structure arranged on the side of a luggage compartment arranged at the rear of the vehicle. A vehicle having this vehicle side structure is not a type of vehicle in which the passenger compartment and the luggage compartment are strictly separated, but a so-called wagon type vehicle in which the passenger compartment and the luggage compartment are arranged within a single vehicle compartment. For example, the luggage compartment of this embodiment is defined as a space behind the driver's seat or a space behind the rear seat. The vehicle side structure will be described below.

[0014] The vehicle side structure of this embodiment has a body structure arranged on the side of the vehicle, and a deck board 10 arranged transversely on the vehicle inner side of the body structure. The vehicle side structure also has a bracket 20 joined to the vehicle inner side of the body structure and supporting the deck board 10, the bracket 20 having a joining portion 24 facing the outer side of the vehicle and joined to the vehicle inner side of the body structure, and a flat portion 21 facing upward of the vehicle, and the deck board 10 is fixed to the flat portion 21 by a fixing member 40. Fixing the deck board 10 to the bracket 20 makes it possible to more stably support the deck board 10. Below, a description will be given of the members and the like that constitute the vehicle side structure.

[0015] First, the vehicle body structure will be described. The vehicle body structure has a plurality of panels arranged on the vehicle inner side of a side body outer panel 2 that constitutes the outermost part of the vehicle body. In this example, as shown in Fig. 5 to Fig. 7, the vehicle body structure has a quarter inner panel 3 arranged on the vehicle width direction inner side of the side body outer panel 2, and a support panel 5 to which a bracket 20 described later is joined. Note that Fig. 5 to Fig. 7 omit illustration of a quarter trim 30 described later.

[0016] The quarter inner panel 3 is a highly rigid part constituting the side of the vehicle body and is made of a metal material. The quarter inner panel 3 is, for example, a panel constituting the side of the vehicle body from the rear of the side door opening 6A to the outer side of the back door opening 7A in the vehicle width direction, and in this example, is disposed on the side of the luggage compartment. That is, the quarter inner panel 3 is a panel disposed so as to connect the rear pillar portion 6 (first pillar portion) disposed at the rear of the side door opening 6A and the back pillar portion 7 (second pillar portion) disposed at the outer side of the back door opening 7A in the vehicle width direction. In addition, a window opening 3a is provided at the upper portion of the quarter inner panel 3 (FIG. 1).

[0017] As shown in Fig. 5 and Fig. 6, the support panel 5 is an inner panel disposed on the vehicle width direction inner side of the side body outer panel 2 and the quarter inner panel 3, disposed in the vehicle vertical direction intermediate portion of the quarter inner panel 3, and extending in the vehicle front-rear direction, and formed of a metal material. The support panel 5 is a highly rigid part capable of reinforcing the vehicle body side portion including the quarter inner panel 3, and is joined to the vehicle width direction inner side of the quarter inner panel 3 by, for example, spot welding. The support panel 5 has an inclined surface 5a that inclines inward in the vehicle width direction toward the vehicle bottom, and an inner surface that extends from the lower end of the inclined surface 5a toward the vehicle bottom. A bracket 20 and the like are joined to the inner surface 5b.

[0018] 1 and 2, a quarter trim 30 is disposed on the inner side in the vehicle width direction of the quarter inner panel 3 and the support panel 5. The quarter trim 30 is made of a resin material and is an interior material that constitutes the side wall of the rear part of the vehicle compartment, in this example, the side wall of the luggage compartment.

[0019] 1, the quarter trim 30 of this embodiment has a plurality of support portions 31, 32, 33 that support the vehicle width direction outer portions of the deck board 10 that is arranged horizontally. In this example, three support portions, namely, a first support portion 31, a second support portion 32, and a third support portion 33, are arranged at intervals from one another in the vertical direction of the vehicle. In this example, the first support portion 31 will be described as an upper support portion, the second support portion 32 as a middle support portion, and the third support portion 33 as a lower support portion.

[0020] As shown in Fig. 2, first support portion 31 protrudes from main surface 35 of quarter trim 30 towards the inside of the vehicle and extends in the front-to-rear direction of the vehicle. Top surface portion 31c of first support portion 31 has a flat surface facing upward of the vehicle, which is a substantially horizontal surface in this example. An outer portion of the underside of deck board 10 is placed on top surface portion 31c. The back side of first support portion 31 (outer side in the vehicle width direction) is recessed towards the inside of the vehicle. In other words, a space portion 30a is formed on the back sides of support portions 31, 32, 33, as shown in Fig. 4.

[0021] 2, the first support portion 31 is provided with a protrusion 31a and a hole 31b. The protrusion 31a is provided on an upper portion of the first support portion 31. In this example, the protrusion 31a protrudes inward in the vehicle width direction from a main surface 35 of the quarter trim 30, and protrudes upward from an upper surface portion 31c of the first support portion 31. The protrusion 31a has a substantially rectangular parallelepiped shape that is integrally formed with the main surface 35 and the upper surface portion 31c.

[0022] Convex portion 31a is disposed inside recesses 12, 13 (described later) of deck board 10, thereby preventing movement of deck board 10. Also, convex portion 31a specifies the position of deck board 10 in the front-to-rear direction of the vehicle. Note that main surface 35 of quarter trim 30 is a design surface facing the vehicle interior.

[0023] 2, the hole 31b of the first support portion 31 is disposed on the upper surface portion 31c of the first support portion 31 at a distance from the protrusion 31a toward the rear of the vehicle. The fixing member 40 can pass through the hole 31b. The hole 31b is circular and formed to pass through the upper surface portion 31c of the first support portion 31, and communicates the space 30a on the rear side of the first support portion 31 with the vehicle cabin. For example, as shown in FIG. 4, the lower portion of the fixing member 40 disposed to pass through the hole 31b is disposed in the space 30a on the rear side of the first support portion 31.

[0024] As shown in FIG. 1, the deck board 10 supported by the first support portion 31 divides the luggage compartment into a space below and a space above the deck board 10. The bottom of the lower space may be formed by the rear floor panel. The second support portion 32 and the third support portion 33 are formed in the same manner as the first support portion 31. That is, like the first support portion 31, the upper surface portion 32c of the second support portion 32 is provided with a convex portion 32a and a hole portion 32b, and the upper surface portion 33c of the third support portion 33 is provided with a convex portion 33a and a hole portion 33b.

[0025] Next, the deck board 10 will be described. As shown in FIG. 1, the deck board 10 is a plate-like member having an upper surface facing upward of the vehicle, and is formed of, for example, a resin material. The outer side of the deck board 10 in the vehicle width direction is supported by the support portions 31, 32, and 33 described above. In this example, the side of the deck board 10 is placed on the upper surface portions 31c, 32c, and 33c of the support portions 31, 32, and 33. The side of the deck board 10 is provided with recesses 12 and 13 that are recessed inward in the vehicle width direction. In this embodiment, the protrusions 31a provided on, for example, the first support portion 31 of the quarter trim 30 are inserted inside the recesses 12 and 13, and the outer side of the lower surface of the deck board 10 in the vehicle width direction is supported in a state of being placed on the upper surface portion 31c of the first support portion 31, and the deck board 10 is supported by the first support portion 31.

[0026] Note that two recesses (front recess 12 and rear recess 13) are provided on one outer side in the vehicle width direction of deck board 10 of this embodiment, and front recess 12 and rear recess 13 are arranged at a distance from each other in the front-to-rear direction of the vehicle. The position of deck board 10 in the front-to-rear direction is determined by engaging one of front recess 12 and rear recess 13 with protrusion 31a. In other words, the front end of deck board 10 of this embodiment can be positioned at two positions.

[0027] Furthermore, in this embodiment, a board through hole 11 that penetrates in the up-down direction is formed in the outer portion of the upper surface of deck board 10 in the vehicle width direction. Board through hole 11 is disposed adjacent to the rear side of front recess 12 and adjacent to the front side of rear recess 13. The opening edge of board through hole 11 is approximately circular. A circular ring member 45 is disposed inside board through hole 11.

[0028] Here, the circular ring member 45 will be described. In this embodiment, as shown in Figs. 3 and 4, the circular ring member 45 is a long member extending in the vertical direction of the vehicle, and is a pipe-shaped member penetrating in the vertical direction, and the outer circumferential surface of the circular ring member 45 is in contact with the inner wall surface of the board through hole 11. The circular ring member 45 is arranged so as to fit into the board through hole 11, and in this example, the circular ring member 45 is press-fitted into the board through hole 11. The upper part of the circular ring member 45 is arranged on the opening edge of the board through hole 11. In this example, the upper end of the circular ring member 45 is arranged so as to correspond to the upper surface of the deck board 10. In addition, an insertion hole 45a extending in the vertical direction is formed in the circular ring member 45.

[0029] As shown in Fig. 4, the board through-hole 11 is formed so that a fixing member 40 can pass therethrough. In this embodiment, the fixing member 40 is disposed so as to pass through an insertion hole 45a of a circular member 45 that is press-fitted into the board through-hole 11. By having the fixing member 40 pass through the insertion hole 45a of the circular member 45 of the board through-hole 11, it becomes possible to restrict horizontal translation of the deck board 10. The structure that fixes the position of the deck board 10 will be described later.

[0030] Next, fixing member 40 will be described. As shown in Fig. 4, fixing member 40 is a member that is arranged to pass through board through hole 11 and hole portion 31b of quarter trim 30. Fixing member 40 in this example is a so-called eye bolt, and has an abutment portion 41 that abuts against the upper surface of deck board 10, a cylindrical portion 42 that extends in the vertical direction of the vehicle, and an annular portion 43 provided at the upper end of cylindrical portion 42 of deck board 10.

[0031] The abutment portion 41 is disposed on the upper part of the cylindrical portion 42, protrudes radially and outwardly from the side surface of the cylindrical portion 42, and is provided along the circumferential direction. The abutment portion 41 is formed in a disk shape that surrounds the upper part of the cylindrical portion 42. The lower surface of the abutment portion 41 is able to abut against the surface of the deck board 10, and covers the opening edge of the board through-hole 11 (the upper end of the annular member 45) from above.

[0032] The cylindrical portion 42 can pass through a board through-hole 11 provided in the deck board 10. In this embodiment, the cylindrical portion 42 is disposed inside an insertion hole 45a of a circular member 45. Here, the inner wall surface of the insertion hole 45a of the circular member 45 is disposed so as to surround the cylindrical portion 42 with a radial gap (gap S) therebetween (FIG. 4). A thread groove is formed on the side surface of the cylindrical portion 42. The formation of the gap S prevents the thread groove from coming into direct contact with the inner wall surface of the insertion hole 45a.

[0033] The annular portion 43 is provided on the upper portion of the cylindrical portion 42 and is an annular portion having a hole penetrating in the horizontal direction. For example, the annular portion 43 is capable of hanging a hook or the like.

[0034] Further, the lower part of the fixing member 40 engages with the flat part 21 of the bracket 20 joined to the body structure. The bracket 20 is made of a metal material, and as shown in Figs. 6 and 7, is joined by, for example, spot welding to an inner surface 5b of the vehicle width direction inner part of the support panel 5 constituting the body structure. As shown in Fig. 4, the bracket 20 is disposed, for example, in a space 30a on the rear side of the first support part 31, and the lower part of the fixing member 40 engages therewith. In this example, the lower part of the cylindrical part 42 of the fixing member 40 engages with the bracket 20. Details of the shape of the bracket 20 will be described below.

[0035] As shown in Figures 7 and 8, the bracket 20 is a member that extends overall from the support panel 5 toward the inside in the vehicle width direction, for example to the space portion 30a on the back side of the first support portion 31, and has a planar portion 21, a joint portion 24, a curved portion 25, and a connection surface portion 26.

[0036] The joint 24 is a so-called vertical wall that faces outward in the vehicle width direction (outside the vehicle), and is joined to the vehicle inner side of the body structure. A flange 24a is provided at the end of the joint 24 to increase surface rigidity (FIG. 8). In this embodiment, the joint 24 is joined to the inner side in the vehicle width direction of the support panel 5 by spot welding or the like. The joint 24 also extends from the curved portion 25, inclining toward the rear of the vehicle as it heads downwards.

[0037] Deck board 10 is attached to flat portion 21 via fixing member 40. Flat portion 21 is a portion that is located on the upper part of bracket 20 and on the inner side in the vehicle width direction, and faces upward of the vehicle. Flat portion 21 has a substantially horizontal surface and, for example, abuts against the back side (lower side) of upper surface portion 31c of first support portion 31. Flat portion 21 is formed with bracket through-hole 22 that penetrates in the vertical direction of the vehicle. For example, with deck board 10 placed on upper surface portion 31c of first support portion 31, fixing member 40 is disposed to penetrate insertion hole 45a of annular member 45 inside board through-hole 11, hole portion 31b provided in first support portion 31, and bracket through-hole 22. In addition, flange 21a is provided at the end of flat portion 21 to increase surface rigidity (FIG. 8).

[0038] The lower end (lower part of the fixing member 40) of the cylindrical portion 42 of the fixing member 40 that passes through the bracket through-hole 22 is located below the flat portion 21 of the bracket 20. In this example, as shown in FIG. 4, for example, a welded nut 23 is attached to the underside of the flat portion 21, and a threaded portion formed on the cylindrical portion 42 of the fixing member 40 is configured to screw into it. As a result, with the deck board 10, the upper surface portion 31c of the first support portion 31, and the flat portion 21 of the bracket 20 overlapping, the deck board 10 is stably fixed to the upper surface portion 31c of the first support portion 31. As a result, the fixing member 40 is prevented from coming off toward the upper side of the deck board 10.

[0039] The curved portion 25 is a portion that curves from an upper portion of the joint portion 24 toward the inside of the vehicle. The curved portion 25 is connected to an outer portion in the vehicle width direction of the planar portion 21. In other words, the curved portion 25 is a portion that connects the upper portion of the joint portion 24 and the outer end portion of the planar portion 21 in the vehicle width direction.

[0040] The connecting surface portion 26 extends inward in the vehicle width direction from the inner end of the curved portion 25 in the vehicle width direction, and is connected to the outer end of the flat portion 21 in the vehicle width direction.

[0041] In addition, the flat portion 21 may extend at an incline toward the front of the vehicle as it moves inward in the vehicle width direction from the curved portion 25. In this example, the flat portion 21 extends at an incline toward the front of the vehicle as it moves inward in the vehicle width direction from the connection surface portion 26.

[0042] The fixing member 40 is configured to be engageable with the flat portion 21 located forward of the joint portion 24 in the vehicle front-rear direction. In this example, the bracket through-hole 22 provided in the flat portion 21 is located forward of the front end of the joint portion 24.

[0043] Since fixing member 40 is engaged with bracket 20 which is joined to a highly rigid vehicle body structure, it has a predetermined rigidity. Therefore, it is possible to effectively restrict movement of deck board 10. Furthermore, by arranging fixing member 40 as described above, even if deck board 10 attempts to move, the side portion of cylindrical portion 42 of fixing member 40 abuts against the inner wall surface of insertion hole 45a of annular member 45, making it possible to effectively restrict movement of deck board 10 in the vehicle front-rear direction and width direction. Furthermore, because abutment portion 41 of fixing member 40 covers the periphery of board through-hole 11 from above, it is also possible to suppress movement of deck board 10 such that it floats up from first support portion 31.

[0044] In this example, even if deck board 10 attempts to move, the side of cylindrical portion 42 of fixing member 40 abuts against the inner wall surface of insertion hole 45a of circular ring member 45 that fits into board through hole 11, making it possible to effectively restrict movement of deck board 10 in the fore-and-aft direction and width direction of the vehicle.

[0045] In addition, because abutment portion 41 of fixing member 40 covers the surface of deck board 10 located around board through hole 11 from above, it is also possible to suppress movement of deck board 10 such as lifting up from first support portion 31.

[0046] For example, as shown in Fig. 5, when an impact load acts on the vehicle from the rear, a back door (not shown) or the like disposed at the rear of the vehicle may deform toward the vehicle cabin. In this case, in accordance with the deformation of the back door or the like, a side body outer panel 2, a quarter inner panel 3, a support panel 5, or the like disposed at the side of the vehicle may deform outward in the vehicle width direction. In Fig. 5, a dashed line L1 shows a state in which the side body outer panel 2 is deformed outward in the vehicle width direction (in the direction of the arrow X1), and a dashed line L2 shows a state in which the support panel 5 is deformed outward in the vehicle width direction. As the support panel 5 and the like deform outward in the vehicle width direction, the quarter trim 30 may also deform, and the locked state of the deck board 10 may be released.

[0047] In contrast, in this embodiment, a restriction structure is provided that can restrict movement of the deck board 10 using a fixing member 40, a bracket 20, etc. In this example, the fixing member 40 passes through board through hole 11 in the side part of the deck board 10, and the lower part of the fixing member 40 engages (screws) with the bracket 20. Therefore, even if the above-mentioned outward deformation occurs, the side part of the fixing member 40 abuts against the inner wall surface of the board through hole 11 of the deck board 10, thereby making it possible to suppress deformation of the vehicle side structure. As a result, it is possible to suppress the release of the locking of the deck board 10, making it possible to more stably support the deck board 10 that is placed in the luggage compartment of the vehicle.

[0048] Furthermore, in this embodiment, bracket 20 curves from joint 24, which is joined to support panel 5 constituting the vehicle body structure, towards deck board 10, and a lower portion of fixing member 40 is engaged with flat portion 21 extending inward in the vehicle width direction. Meanwhile, support panel 5 to which bracket 20 is joined is a highly rigid member, and further, quarter inner panel 3 to which support panel 5 is joined is also a highly rigid member. In other words, bracket 20 is indirectly fixed to the highly rigid vehicle body structure. Therefore, deck board 10 can be stably fixed to the side of the vehicle.

[0049] As described above, the quarter inner panel 3 is disposed so as to connect the rear pillar portion 6 disposed at the rear of the side door opening 6A and the back pillar portion 7 disposed on the outer side of the back door opening 7A in the vehicle width direction. In other words, the quarter inner panel 3 is a panel that is connected to a pillar portion having high rigidity. The bracket 20 is indirectly joined to the quarter inner panel 3, so a predetermined rigidity is ensured. This makes it possible to stably support the deck board 10.

[0050] In this embodiment, the bracket 20 is provided with a curved portion 25. By concentrating stress on the curved portion 25 and deforming the curved portion 25, it is possible to suppress breakage of the bracket 20. In other words, the impact energy generated by an impact load due to a rear-end collision or the like is converted into deformation energy that deforms the bracket 20, absorbing the impact and suppressing breakage of the bracket 20.

[0051] Furthermore, in this embodiment, fixing member 40 is disposed further forward of joint 24. For example, when an impact load acts on the rear of the vehicle from the rear of the vehicle toward the front of the vehicle, joint 24 is displaced toward fixing member 40. The displacement of joint 24 absorbs the impact energy and makes it possible to prevent bracket 20 from breaking. By preventing bracket 20 from breaking, it is possible to maintain the supported state of deck board 10.

[0052] In this embodiment, the flat surface portion 21 and the joint portion 24 extend at an incline as described above. Furthermore, the fixing member 40 extending in the vehicle vertical direction is disposed forward of the joint portion 24. Therefore, when an impact load such as a rear collision acts on the rear of the vehicle, the flat surface portion 21, the connecting surface portion 26, and the curved portion 25 can be deformed so as to rotate around the fixing member 40 as the radial center. In addition, the flat surface portion 21 and the connecting surface portion 26 can be deformed so as to be extended in the vehicle width direction due to the action of the impact load. For example, as shown in the schematic diagram of FIG. 9, when an impact load due to a rear collision acts on the rear of the vehicle, when the joint portion 24 deforms toward the outside in the vehicle width direction (the right side in FIG. 9) and toward the front of the vehicle, the flat surface portion 21 and the connecting surface portion 26 can be deformed so as to be extended in the vehicle width direction. At this time, the movement amount of the bracket through hole 22 can be made smaller than other parts.

[0053] For example, even if side body outer panel 2 etc. deforms outward in the vehicle width direction due to an impact load caused by a rear-end collision and joint portion 24 also deforms outward in the vehicle width direction as a result, flat portion 21 deforms from an inclined state so as to be stretched outward in the vehicle width direction, thereby reducing the amount of movement of fixing member 40. As a result, the engagement between deck board 10 and flat portion 21 can be maintained.

[0054] Furthermore, as described above, fixing member 40 of the present embodiment has a contact portion 41 that abuts against deck board 10, and the upper surface 31c of first support portion 31 and deck board 10 are clamped between abutment portion 41 and the flat surface portion 21 of bracket 20. In this state, the lower portion of fixing member 40 is engaged with flat surface portion 21 of bracket 20, so that abutment portion 41 of fixing member 40 can effectively press deck board 10, making it possible to more effectively restrict movement of deck board 10.

[0055] Furthermore, in this embodiment, quarter trim 30 is provided with protruding portions 31a, 32a, 33a that protrude in the vehicle width direction, and deck board 10 has side portions with recessed portions 12, 13 into which protruding portions 31a, 32a, 33a engage. By fitting recessed portions 12, 13 into protruding portion 31a, it becomes possible to easily position deck board 10, and furthermore, movement of deck board 10 in the fore-and-aft direction becomes more easily restricted (FIG. 2).

[0056] Furthermore, in this embodiment, fixing member 40 engages with deck board 10 located between front recess 12 and rear recess 13. In other words, fixing member 40 engages with flat surface portion 21 of bracket 20 at a position adjacent to the recess in the front-to-rear direction. By arranging recesses 12, 13, which restrict the movement of deck board 10 and position it, near fixing member 40, which firmly restricts the movement of deck board 10, and flat surface portion 21, it becomes possible to stably position deck board 10.

[0057] As shown in FIG. 4, a board through hole 11 is formed on the outer side of deck board 10 in the vehicle width direction, through which fixing member 40 can pass, and abutment portion 41 of fixing member 40 is positioned so as to cover the opening edge of board through hole 11 and the upper end of circular member 45 from above.

[0058] Furthermore, in this embodiment, as described above, the outer peripheral surface of the cylindrical portion 42 and the inner wall surface of the insertion hole 45a are arranged to form a gap S. Providing the gap S makes it possible to absorb variations in the dimensional accuracy of each component. For example, even if variations occur in the position of the board through hole 11 of the deck board 10, the outer diameter dimension of the deck board 10, etc., it is possible to pass the fixing member 40 through the board through hole 11 via the annular member 45. As a result, manufacturing of the part becomes easier.

[0059] As a result, when the deck board 10 unintentionally moves parallel to the surface due to an impact load or the like, the load acting on the inner wall surface of the board through hole 11 can be easily dispersed around the periphery of the inner wall surface. Furthermore, if the annular member 45 is configured to fit into the board through hole 11, it is also possible to increase the rigidity of the board through hole 11. As a result, the deck board 10 can be fixed more stably by the fixing member 40 and the bracket 20.

[0060] Furthermore, because the circular ring member 45 is fitted into the board through hole 11, the screw grooves provided in the cylindrical portion 42 of the fixing member 40 are configured not to come into direct contact with the inner wall surface of the board through hole 11. In this example, a gap S is formed between the screw grooves and the inner wall of the insertion hole 45a of the circular ring member 45. This makes it possible to prevent the inner wall surface of the board through hole 11 and the inner wall surface of the insertion hole 45a of the circular ring member 45 from being damaged due to contact with the screw grooves, allowing the deck board 10 to be used for a long period of time. Note that, because the circular ring member 45 is a separate member from the deck board 10, even if the inner wall of the circular ring member 45 is damaged, only the circular ring member 45 needs to be replaced.

[0061] The description of the present embodiment is merely an example for explaining the present invention, and does not limit the invention described in the claims. Furthermore, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications are possible within the technical scope described in the claims.

[0062] In addition, in this embodiment, the engaging portion is the bracket 20 joined to the support panel 5, but this is not limited thereto. The bracket 20 may be configured to be joined to the quarter inner panel 3. In addition, in this embodiment, the quarter trim 30 is provided with the protruding portions 31a, 32a, 33a, but this is not limited thereto. For example, a recessed portion may be provided. In this case, it is sufficient to provide a protruding portion on the side portion of the deck board 10.

[0063] Furthermore, while fixing member 40 is configured to pass through board through hole 11 provided in deck board 10, this is not limiting. For example, fixing member 40 may be disposed inside a recess provided in deck board 10.

[0064] Furthermore, in this embodiment, the fixing of deck board 10 when deck board 10 is placed on first support portion 31 has been described, but this is not limited to the above. By changing the position of bracket 20, deck board 10 can also be fixed to second support portion 32 or third support portion 33. [Explanation of symbols]
