Description

[Technical field]

[0001] The technology disclosed in this specification relates to a vehicle luggage compartment structure. [Background technology]

[0002] Conventionally, there have been proposed techniques for holding a deck board, which constitutes the floor of a vehicle's luggage compartment, in an upright position. For example, Patent Document 1 discloses a configuration in which a pair of grooves are formed on both sides of the inner edge of a sub-trunk disposed in a recess in a floor panel of a trunk room, and when the floor board (deck board) is opened, the lower end of the deck board is inserted into the grooves to hold the floor board upright.

[0003] Furthermore, Patent Document 2 discloses a configuration in which the rear side of the deck board is lifted upward around the front end of the deck board as a rotation center, a hook provided on the underside of the deck board is removed, and this hook is hooked onto a rod provided on the seat, thereby holding the deck board in an upright position.

[0004] [Patent Document 1] JP 2001-63471 A [Patent Document 2] JP 2012-91644 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the technology described in Patent Document 1, items stored in the sub-trunk may get in the way and the floorboard may not be able to be inserted into the groove. In addition, if the groove is shallow, the floorboard may not be able to stand upright. In addition, since the groove is formed in a member disposed below the floorboard, restrictions on the position of the groove are likely to arise due to the relationship with the body and surrounding parts, resulting in low design freedom. Furthermore, when inserting the floorboard into the groove or removing it from the groove, the floorboard needs to be lifted up, which may be a heavy burden on the worker.

[0006] Furthermore, in the configuration described in Patent Document 2, a hook must be provided on the underside of the deck board, which increases the number of parts and makes the configuration complicated. Also, a new mating member must be provided for the hook to be hooked onto.

[0007] The technology disclosed in this specification was developed based on the above-mentioned circumstances, and its object is to provide a vehicle luggage compartment structure that can easily maintain the upright position of the deck board with a simple configuration. [Means for solving the problem]

[0008] The technology disclosed in this specification is a vehicle luggage space structure comprising: a deck board that forms the floor of the luggage space of a vehicle and has a rear end that can be lifted around a rotation center at the front side in the vehicle travel direction; a tonneau board that is arranged at a spaced position above the deck board and can be folded into at least two or more parts by folds extending in the vehicle width direction; and side trim that forms the side surfaces of the luggage space and has support parts that protrude inwardly of the luggage space and can support the side ends of the tonneau board from below, wherein the tonneau board can be held in a mountain-folded state in which it is folded into a mountain shape that protrudes upward by the folds, and the deck board can be held in an upright state by abutting and hooking its rear end against the inner surface of the mountain shape of the tonneau board in the mountain-folded state.

[0009] According to the above-mentioned configuration, the deck board can be easily held in an upright position by simply folding the tonneau board in a mountain-folded state and abutting the rear end of the deck board against the inner surface of the mountain-shaped tonneau board. Also, there is no need for a dedicated holding member for holding the deck board in an upright position as in the conventional method, which reduces the number of parts and simplifies the structure of the luggage compartment.

[0010] The support portion may be in the form of a shelf extending in the fore-aft direction of the vehicle, and the tonneau board may be held in a mountain-folded state at any position on the upper surface of the support portion by friction. With this configuration, the standing angle of the deck board can be freely set within a certain range.

[0011] The rear plate portion of the tonneau board that is disposed on the rear side across the mountain fold may be capable of being installed so as to incline rearward from its lower end to its upper end.

[0012] With the above configuration, the plate portion connected to the rear plate portion and the front side via the fold overlaps the rear plate portion in the up-down direction, so the rear plate portion is in a taut state and the lower end of the rear plate portion is less likely to move rearward compared to when the rear plate portion has a flared mountain-like shape. In other words, even if the deck board is subjected to a force in the direction in which the mountain-folded tonneau board unfolds (the direction in which the rear plate portion moves rearward) due to a force that tries to tip the deck board over, the mountain-like shape of the tonneau board is less likely to collapse and the deck board can be more reliably maintained in an upright state.

[0013] The tonneau board has two of the creases and can be folded into three, and comprises a front plate portion disposed at the front, a central plate portion connected to the front plate portion via one of the creases, and a rear plate portion connected to the central plate portion via the other crease, and the front plate portion is provided with a fixing portion for removably fixing the front plate portion to the support portion, and the central plate portion and the rear plate portion may form a mountain shape.

[0014] According to the above-mentioned configuration, since the front plate can be fixed to the support, it is possible to prevent the tonneau board from moving unnecessarily relative to the support when forming the mountain shape of the tonneau board with the central plate and the rear plate. Also, by folding the tonneau board in three, it is possible to use the space in the luggage compartment more widely compared to when it is folded in two.

[0015] The support portion may be in the form of a flange that protrudes from the side surface of the luggage compartment and extends in the front-rear direction of the vehicle, and the fixing portion may have a main body that protrudes from the underside of the front plate, and a fitting groove that can be fitted into the support portion may be provided in the main body. With this configuration, it is possible to realize an embodiment in which the front plate is fixed to the support portion when the tonneau cover is folded in three.

[0016] The fitting groove may be open toward the outside of the luggage compartment and toward the front, with its rear end being closed by the rear wall, and the support part may be provided with an escape recess that allows the main body part to escape downward from above the support part, cut out from an edge part inside the luggage compartment toward the outside of the luggage compartment, and the front plate part may be moved forward with the main body part escaped into the escape recess, and a part of the support part that is located forward of the escape recess may be fitted into the fitting groove, thereby making it possible to fix the front plate part to the support part. With this configuration, the front plate part can be easily attached to and detached from the support part. Effect of the Invention

[0017] The technology disclosed in this specification makes it possible to provide a vehicle luggage compartment structure that can easily maintain the upright state of the deck board with a simple configuration. [Brief description of the drawings]

[0019] A vehicle luggage compartment structure 1 according to one embodiment will be described with reference to Fig. 1 to Fig. 25. In each figure, the arrows FR and RR indicate the front and rear of the vehicle, respectively, the arrows UP and DW indicate the upper and lower sides of the vehicle, respectively, and the arrows R and L indicate the right and left sides of the vehicle travel direction, respectively.

[0020] 1 is a perspective view of a luggage compartment 10 of this embodiment as viewed obliquely from the rear of the vehicle. The luggage compartment 10 is covered from the rear of the vehicle by a back door (not shown), and by opening the back door, luggage can be loaded and unloaded from the luggage compartment 10.

[0021] The luggage compartment 10 has an accommodation space S1 surrounded by a seat back 11A of a rear seat 11 forming a front wall of the vehicle, a pair of deck side trims 21, 21 forming a side wall 20 and a back side trim 23, 23 arranged above the deck side trims 21, 21, and a deck board 30 forming a floor surface (see FIG. 3). The deck board 30 is in the form of a plate extending horizontally, and luggage and other loadable items can be placed on its upper surface 30A. A plate-shaped tonneau board 40 is provided above the deck board 30 and serves to divide the luggage compartment 10 in the vertical direction and to shield luggage placed in the luggage compartment 10 from the outside.

[0022] As shown in Fig. 2, deck board 30 has a generally rectangular plate shape with both corners of the rear end cut out in a stepped shape, and is configured to be rotatable from a horizontal state to an upright state around a front end portion (hereinafter referred to as front end portion 31) extending in the vehicle width direction as the center of rotation (see Figs. 3 and 4). Specifically, the member disposed in front of deck board 30 has a portion extending in the vehicle width direction and having an L-shaped cross section formed by upright wall portion 12 and bottom wall portion 13, and deck board 30 has rear end portion 32 which is rotatable around front end portion 31 as the center of rotation by pressing front end portion 31 against the inside of this bent portion.

[0023] A storage recess S2 is provided under the deck board 30, and luggage, a spare tire, tools, and other on-board items can also be stored under the floor. When the deck board 30 is in a horizontal position, the storage recess S2 is closed from above (see FIG. 3), and when in an upright position, the storage recess S2 is open (exposed) (see FIG. 4). A foldable grip portion 33 is provided on the upper surface 30A of the deck board 30 for lifting up the rear end portion 32 of the deck board 30 in the horizontal position (see FIG. 2).

[0024] The side walls 20 arranged on the sides of the luggage compartment 10 are mainly composed of a pair of deck side trims 21, 21 and a pair of back side trims 23, 23 arranged above the deck side trims 21, 21. In the following explanation, the right side of both side walls 20 of the luggage compartment 10 in the vehicle travel direction will be explained. The deck side trim 21 and the back side trim 23 are members that extend substantially vertically and in the front-rear direction of the vehicle. The deck side trim 21 and the back side trim 23 are substantially flat plate-shaped following a vehicle panel (not shown) that forms the outer shell of the vehicle.

[0025] 1 and 5, the tonneau cover 40 is mainly composed of three plate-shaped board portions 41, 42, 43 that are connected in the fore-and-aft direction of the vehicle. Hereinafter, the three board portions 41, 42, 43 will be referred to as a first board portion (an example of a front board portion) 41, a second board portion (an example of a central board portion) 42, and a third board portion (an example of a rear board portion) 43, in that order from the front.

[0026] Each of the three boards 41, 42, 43 has a rectangular plate shape that is long in the vehicle width direction. The boards 41, 42, 43 are connected together via hinges 44, 45 (an example of a fold), and can be folded along the hinges 44, 45 (see Figs. 6 to 8). In the unfolded state in which the hinges 44, 45 are extended, the tonneau cover 40 is arranged so that the plate surfaces of the boards 41, 42, 43 are arranged side by side along the horizontal direction. In the unfolded state, the front surfaces 41A, 42A, 43A of the boards 41, 42, 43 face upward, and the back surfaces 41B, 42B, 43B face downward (see Fig. 6).

[0027] More specifically, the second board portion 42 is connected to the rear end of the first board portion 41 arranged on the front side of the vehicle in the unfolded tonneau cover 40 via the first hinge portion 44 so as to be able to be folded back between the first board portion 41 and the second board portion 42. As shown in FIG. 6, the first hinge portion 44 is provided on the front side of the first board portion 41 and the second board portion 42 over the entire width of the vehicle in a manner that connects the front surface 41A (upper surface in FIG. 6) of the first board portion 41 and the front surface 42A of the second board portion 42. In other words, the first hinge portion 44 has a thin shape formed by providing a groove-shaped portion that is recessed along the width of the vehicle from the rear surface side of the tonneau cover 40. The first board portion 41 and the second board portion 42 are able to be folded back in a direction in which their front surfaces 41A, 42A face each other, with the first hinge portion 44 as a fold (see FIGS. 7 and 8).

[0028] In addition, the third board portion 43 is connected to the rear end of the second board portion 42 in the unfolded state via the second hinge portion 45 so as to be able to be folded back between the second board portion 42 and the third board portion 43. As shown in FIG. 6, the second hinge portion 45 is provided on the back side of the second board portion 42 and the third board portion 43 over the entire vehicle width direction in a form that connects the back side 42B (the lower surface in FIG. 6) of the second board portion 42 and the back side 43B of the third board portion 43. In other words, the second hinge portion 45 has a thin-walled shape formed by providing a groove-shaped portion that is recessed from the front side of the tonneau cover 40 along the vehicle width direction. The second board portion 42 and the third board portion 43 are able to be folded back in a direction in which their back sides 42B, 43B face each other, with the second hinge portion 45 as a fold (see FIG. 7 and FIG. 8).

[0029] With this configuration, the tonneau board 40 can be folded into a Z shape by folding back the second board portion 42 at the first hinge portion 44 with the first board portion 41 at the bottom, and further folding back the third board portion 43 at the second hinge portion 45 (see Figures 7 and 8).

[0030] The first hinge portion 44 and the second hinge portion 45 can be formed by, for example, covering the base materials for the multiple board portions formed as separate bodies with a continuous flexible skin. Alternatively, they can be formed by integrally molding the base materials of the adjacent board portions and thinning the joint portion. In other words, they can be formed by crushing a part of the base material of the tonneau board in the thickness direction, which is called an integral hinge.

[0031] The first hinge portion 44 and the second hinge portion 45 of this embodiment are a combination of these. Specifically, the tonneau cover 40 of this embodiment is formed by covering the surface (upper surface) of a base material 47 made of synthetic resin such as polypropylene with a skin 48 such as nonwoven fabric or fabric (see FIG. 6). The base materials 47 constituting each of the board portions 41, 42, 43 are integrally molded via a thin portion, and the skin 48 covers the entire surface of each base material 47 at once. With this configuration, the first hinge portion 44 and the second hinge portion 45 are both configured such that the surface side of the thin resin portion is covered with the skin 48. The back surfaces of the first hinge portion 44 and the second hinge portion 45 are not covered with the skin 48, and the base material 47 is exposed. The skin 48 is also configured to wrap around and cover the front end and rear end of the tonneau cover 40 in the unfolded state (see FIG. 6). For convenience, the skin 48 is omitted in FIG.

[0032] The side walls 20 of the luggage compartment 10 are provided with tono board support portions (one example of a support portion) 53 that support both side ends in the vehicle width direction of the tono board 40 from below (see Figs. 6 to 10). The tono board support portions 53 are provided on both the left and right sides of the side walls 20. The tono board support portions 53 are formed by support members 50 attached to the side walls 20.

[0033] Fig. 12 is a perspective view of the support member 50 (for the right side wall), and Fig. 13 is a plan view of the same. The support member 50 includes a vertical wall portion 51 that is in the shape of a belt extending in the front-rear direction and whose plate surface extends in a direction (almost vertical direction) along the side wall 20 of the luggage compartment, a claw portion 52 that protrudes from the outer surface of the vertical wall portion 51 toward the outside of the compartment, a tonneau board support portion 53 that is in the shape of a flange that protrudes from the lower end of the vertical wall portion 51 toward the inside of the compartment and extends in the front-rear direction, and a horizontal wall portion 54 (see Fig. 14) that is the bottom surface of the tonneau board support portion 53 and that extends to the outside of the compartment from the bottom surface that is inclined slightly diagonally downward toward the outside of the compartment and along the bottom surface. The upper surface of the tonneau board support portion 53 extends in the horizontal direction. In addition, a positioning protrusion 55 that protrudes toward the inside of the compartment is provided near the rear end of the vertical wall portion 51. Furthermore, side wall portion 54 is provided with irradiation holes 57 that pass light from an irradiation portion that irradiates open storage recess S2 when the deck board is in an upright position as described below (see FIG. 10).

[0034] 14, the upper end of the support member 50 is fixed to the back side trim 23 by engaging the claw portion 52 with the hole edge of an engaging hole provided in the back side trim 23. Also, the lower end of the support member 50 is fastened and fixed to the upper end of the deck side trim 21 via the intervening member 26 having an L-shaped cross section at the end portion on the outer side of the cabin of the lateral wall portion 54. In other words, the support member 50 is attached to the side wall 20 so as to straddle the back side trim 23 and the deck side trim 21.

[0035] Meanwhile, a board fixing member (one example of a fixing member) 60 is attached to the rear surface 41B of the first board portion 41 of the tonneau cover 40 near corners located at the front end of the vehicle and both ends in the vehicle width direction (see FIG. 5). The board fixing member 60 has a substantially box-shaped main body portion 61 as shown in FIGS. 14 to 19, and is fixed to the rear surface 41B of the first board portion 41 using, for example, screws B within an attachment recess 63 recessed upward from a bottom wall 62 of the main body portion 61.

[0036] The board fixing member 60 has a fitting groove 64 that extends in the front-rear direction on the outer side of the vehicle compartment of the mounting recess 63 and opens toward the outside of the vehicle compartment and toward the front. The rear end of the fitting groove 64 is closed by an abutment wall portion (an example of a rear wall) 65. The groove width (length in the vertical direction) and groove depth (length in the vehicle width direction) of the fitting groove 64 are set to dimensions that allow the above-mentioned flange-shaped tonneau board support portion 53 to be fitted inside (see FIG. 14).

[0037] A downwardly inclined portion 67 is provided on the front end side of the lower wall 66 of the fitting groove 64 (see FIG. 18). In addition, a plurality of ribs 69 are provided on the inner surface of the fitting groove 64, extending in a direction (up-down direction and vehicle width direction) intersecting the extension direction of the fitting groove 64 (front-rear direction).

[0038] Near the front end of the flange-shaped tonneau board support part 53, there is provided an escape recess 56 that is sized to allow the lower portion of the board fixing member 60 to escape below the tonneau board support part 53, cut out from the edge inside the vehicle compartment toward the outside of the vehicle compartment (see Figures 12 and 13). Hereinafter, the portion of the tonneau board support part 53 that is located forward of the escape recess 56 will be referred to as the fitted portion 53A.

[0039] Furthermore, when the tonneau cover 40 is in the unfolded state, the third board portion 43 has a positioning recess 46 recessed from its side edge at a position corresponding to the positioning protrusion 55 described above (see FIG. 5). A fitting member 49 that fits around the positioning protrusion 55 is provided within the positioning recess 46 (see FIGS. 24 and 25). Hereinafter, with regard to the third board portion 43, the end portion that is located on the front side when the tonneau cover 40 is in the unfolded state and that is connected to the second hinge portion 45 will be referred to as the hinge portion side end portion 43C, and the end portion that is located on the rear side and that is disposed opposite the hinge portion side end portion 43C will be referred to as the opposite side end portion 43D.

[0040] When attaching the tonneau board 40 to the luggage compartment 10 (support member 50), first, the tonneau board 40 is folded (folded in three), the board fixing member 60 fixed to the underside 41B of the first board portion 41 of the tonneau board 40 is fitted into the escape recess 56 from above the tonneau board support portion 53, and the first board portion 41 (the tonneau board 40 in the folded state) is placed on the upper surface of the tonneau board support portion 53 (see Figures 20 and 22). Next, the first board portion 41 is slid forward (see Figures 21 and 23). This causes the fitted portion 53A of the tonneau board support portion 53 to enter the fitting groove 64 of the board fixing member 60 from the front, and the board fixing member 60 can be fixed to the tonneau board support portion 53, and ultimately the tonneau board 40 can be fixed to the side wall 20.

[0041] At this time, since the front portion of the fitting groove 64 is provided with an inclined portion 67 that is inclined in a direction widening toward the front, the fitted portion 53A of the tonneau board support portion 53 is smoothly guided into the correct position relative to the fitting groove 64. Also, a plurality of ribs 69 provided on the inner surface of the fitting groove 64 are set to abut against the fitted portion 53A from above and below, which reduces rattling of the board fixing member 60 relative to the tonneau board support portion 53, and ultimately rattling of the tonneau board 40 relative to the side wall 20.

[0042] When the fitted portion 53A of the tonneau cover support portion 53 penetrates to the depth of the fitting groove 64 of the board fixing member 60 and the rear end surface of the fitted portion 53A abuts against the rib 69 provided on the abutment wall portion 65 of the fitting groove 64, the forward movement of the first board portion 41 (tonno cover 40) relative to the side wall 20 is restricted, and the abutment between the rear end surface of the fitted portion 53A and the rib 69 of the abutment wall portion 65 of the fitting groove 64 gives the worker a sense of restraint. In other words, the worker can recognize that the first board portion 41 has reached the correct mounting position. In this way, the first board portion 41 of the tonneau cover 40 is positioned and fixed relative to the side wall 20 of the luggage compartment 10.

[0043] In this state, when the tonneau cover 40 is changed from the folded state to the unfolded state by moving the folded third board portion 43 rearward, the positioning protrusions 55 of the support members 50 fit into the fitting members 49 provided in the positioning recesses 46 of the third board portion 43, and the third board portion 43 is positioned relative to the side walls 20 (see Figures 24 and 25). This allows the unfolded tonneau cover 40 to stably maintain its shape and installed position.

[0044] Next, a method for holding the deck board 30 upright will be described. When placing the deck board 30 in an upright state, first, the rear end 32 of the deck board 30 is lifted using the gripping portion 33, and the rear end 32 is moved upward with the front end 31 as the center of rotation. At the same time, the positioning recess 46 (fitting member 49) of the third board portion 43 of the tonneau board 40 in the unfolded state is removed from the positioning protrusion 55, and the opposite end 43D of the third board portion 43 is moved forward along the tonneau board support portion 53 so that the second hinge portion 45 is bent in a mountain shape protruding upward, while the second board portion 42 and the third board portion 43 are raised in a mountain shape. Alternatively, the second board portion 42 and the third board portion 43 of the tonneau board 40 in the folded state are raised in a mountain shape.

[0045] Next, the opposite end 43D of the third board portion 43 in the standing state is lifted slightly upward from the tono board support portion 53, the rear end 32 of the lifted deck board 30 is placed inside the mountain-shaped portion of the tono board 40 (between the second board portion 42 and the third board portion 43), and the opposite end 43D of the lifted third board portion 43 is placed again on the upper surface of the tono board support portion 53 as shown in Fig. 9. Alternatively, the tono board 40 in the folded state may be lifted at this point and raised in a mountain shape so as to cover the rear end 32 of the deck board 30. When the deck board 30 is released in this state or when the deck board 30 is tilted backward, the rear end 32 of the deck board 30 comes into contact with the rear surface 43B of the third board portion 43 in the standing state from the front side, and the deck board 30 is hooked on the third board portion 43 so as not to fall backward. Alternatively, tonneau board 40 may be raised in a mountain shape so as to cover rear end 32 of deck board 30, and third board portion 43 may be brought close to and in contact with rear end 32 of deck board 30 from the rear side (see FIG. 10). In this way, rear end 32 of deck board 30 is supported by the inner surface of the mountain shape of tonneau board 40 in a mountain-folded state (rear surface 43B of third board portion 43), thereby making it possible to maintain deck board 30 in an upright state.

[0046] At this time, since the opposite end 43D of the third board portion 43 is rolled up by the cover 48, the rear end of the tonneau board 40 (the opposite end 43D of the third board portion 43) which stands up in a mountain shape is held in any position relative to the tonneau board support portion 53 by the frictional force between the cover 48 and the tonneau board support portion 53. In other words, the frictional force between the cover 48 and the tonneau board support portion 53 is made greater than the component of force that pushes the third board portion 43 rearward when the tonneau board 40 falls over due to gravity.

[0047] In addition, at this time, the third board portion 43 in the upright state is preferably installed so as to be inclined rearward from its lower end (opposite end 43D) to its upper end (hinge portion side end 43C) as shown in Fig. 10. By raising the third board portion 43 at such an angle, the second board portion 42 wraps over the third board portion 43 and holds down the third board portion 43 from above, so that the opposite end 43D of the third board portion 43 is less likely to move rearward than when the third board portion 43 is in a mountain shape with a wide base as shown in Fig. 9. Moreover, since the first board portion 41 is fixed to the tonneau board support portion 53, the third board portion 43 is in a taut state even when pushed rearward by the deck board 30, and the opposite end 43D of the third board portion 43 is more difficult to move rearward. In other words, even if the deck board 30 is subjected to a force trying to tip over in a direction in which the folded tonneau board 40 unfolds (the direction in which the opposite end 43D of the third board portion 43 moves rearward), the mountain shape of the tonneau board 40 is unlikely to collapse, and the upright state of the deck board 30 can be more reliably maintained.

[0048] The vehicle luggage compartment structure 1 of this embodiment is as described above, and its operation and effect will be described below. The vehicle luggage compartment structure 1 of this embodiment comprises a deck board 30 which constitutes the floor surface of the luggage compartment 10 of the vehicle and whose rear end 32 can be lifted around a pivot center at the front side (front end 31) in the vehicle travel direction, a tonneau board 40 which is arranged at a spaced position above the deck board 30 and can be folded into three by a first hinge portion 44 and a second hinge portion 45 which extend in the vehicle width direction, and a hinge member 45 which constitutes the side wall 20 of the luggage compartment 10 and protrudes inward of the luggage compartment 10 to support the side end of the tonneau board 40 from below. The tonneau board 40 can be held in a mountain-folded state in which it is bent into a mountain shape that protrudes upward by the second hinge portion 45, and the deck board 30 can be held in an upright state by having its rear end portion 32 abut and hooked against the inner surface of the mountain shape of the tonneau board 40 (the back surface 43B of the third board portion 43).

[0049] According to the above configuration, deck board 30 can be easily held in an upright position by simply folding tonneau board 40 and abutting rear end 32 of deck board 30 against the inner surface (rear surface 43B of third board portion 43) of mountain-shaped tonneau board 40. Also, there is no longer a need for a dedicated holding member for holding deck board 30 in an upright position as in the past, which reduces the number of parts and simplifies the structure of luggage compartment 10.

[0050] Tonoboard support portion 53 is shaped like a shelf extending in the front-to-rear direction of the vehicle, and tonoboard 40 can be held in a mountain-folded state by friction at any position on the upper surface of tonoboard support portion 53. With this configuration, the erect angle of deck board 30 can be freely set within a certain range.

[0051] The third board portion 43, which is disposed on the rear side of the second hinge portion 45 that is folded in a mountain shape, can be installed so as to be inclined toward the rear side from its lower end (opposite end portion 43D) to its upper end (hinge portion side end portion 43C). With this configuration, the second board portion 42, which is connected to the front side of the third board portion 43 via the second hinge portion 45, overlaps the third board portion 43 in the up-down direction, so that the third board portion 43 is in a taut state, and the lower end (opposite end portion 43D) of the third board portion 43 is less likely to move rearward compared to when the third board portion 43 is in a mountain shape with a wide base. In other words, even if the deck board 30 receives a force in a direction in which the mountain-folded tono board 40 unfolds (the direction in which the third board portion 43 moves rearward) due to a force that tries to tip the deck board 30, the mountain shape of the tono board 40 is less likely to collapse, and the upright state of the deck board 30 can be more reliably maintained.

[0052] The tonneau board 40 has a first hinge portion 44 and a second hinge portion 45 and can be folded into three, and comprises a first board portion 41 arranged at the front, a second board portion 42 connected to the first board portion 41 via the first hinge portion 44, and a third board portion 43 connected to the second board portion 42 via the second hinge portion 45. The first board portion 41 is provided with a board fixing member 60 for removably fixing the first board portion 41 to the tonneau board support portion 53, and the second board portion 42 and the third board portion 43 form a mountain shape.

[0053] According to the above configuration, the first board portion 41 can be fixed to the tono board support portion 53, so that when the tono board 40 is formed into a mountain shape by the second board portion 42 and the third board portion 43, it is possible to prevent the tono board 40 from moving unnecessarily relative to the tono board support portion 53. Furthermore, by folding the tono board 40 in three, the space of the luggage compartment 10 can be used more widely than when it is folded in two.

[0054] The tonneau board support portion 53 is shaped like a flange that protrudes from the side surface of the luggage compartment 10 and extends in the front-to-rear direction of the vehicle, and the board fixing member 60 has a main body portion 61 that protrudes toward the rear surface 41B of the first board portion 41, and the main body portion 61 is provided with a fitting groove 64 that can fit into the tonneau board support portion 53. This configuration makes it possible to realize an embodiment in which the first board portion 41 is fixed to the tonneau board support portion 53 when the tonneau board 40 is folded in three.

[0055] The fitting groove 64 opens toward the outside of the luggage compartment and toward the front, and its rear end is closed by abutment wall portion 65, and the tonneau board support portion 53 is provided with an escape recess 56 that allows the main body portion 61 to escape downward from above the tonneau board support portion 53, cut out from the edge inside the luggage compartment toward the outside of the luggage compartment, and with the main body portion 61 escaped into the escape recess 56, the first board portion 41 is moved forward and the fitted portion 53A, which is the portion of the tonneau board support portion 53 disposed forward of the escape recess 56, is fitted into the fitting groove 64, thereby making it possible to fix the first board portion 41 to the tonneau board support portion 53. With this configuration, the first board portion 41 can be easily attached to and detached from the tonneau board support portion 53.

[0056] <Other embodiments> The technology disclosed in this specification is not limited to the embodiments described above and illustrated in the drawings, and for example, the following embodiments are also included within the technical scope.

[0057] (1) In the above embodiment, the tonneau cover 40 is folded into three, but the tonneau cover may be folded in two or into four or more. Even when folded into three, the tonneau cover is not limited to the above embodiment, and may be configured such that the first board portion 41 and the second board portion 42 form a mountain shape and the rear end portion 32 of the deck board 30 abuts against the second board portion 42.

[0058] (2) In the above embodiment, a configuration has been disclosed in which the rear end (opposite end 43D) of the third board portion 43 of the tonneau board 40 in a mountain-folded state is held on the upper surface of the tonneau board support portion 53 by frictional force, but the method of holding the tonneau board 40 in a mountain-folded state is not limited to frictional force. For example, a groove into which the opposite end 43D of the third board portion 43 is fitted may be formed on the upper surface of the tonneau board support portion 53, thereby holding the position of the opposite end 43D of the third board portion 43.

[0059] (3) The mountain-fold shape of the tonneau cover 40 may be flared at the bottom.

[0060] (4) The board fixing member 60 of the tonneau cover 40 may be omitted.

[0061] (5) In the above embodiment, the tonneau cover support portion 53 is flange-shaped. However, a tonneau cover support portion having a stepped (shelf-shaped) shape like a staircase is also within the technical scope of the invention.

[0062] (6) In the above embodiment, a relief recess 56 is provided in the flange-shaped tono board support portion 53, and the mating portion 53A of the tono board support portion 53 is engaged with the mating groove 64 while the main body portion 61 of the board fixing member 60 is allowed to escape into the relief recess 56. However, the form in which the tono board support portion and the mating groove are engaged is not limited to the above embodiment; for example, the relief recess may be omitted and the mating groove may be engaged from the rear end of the tono board support portion.
