Description

[Technical Field]

[0001] The present invention relates to a movable gate for a vehicle. [Background technology]

[0002] A lightweight truck bed with a small number of parts is known, in which a floor board, floor joists, front board, left side board, right side board, and a plurality of rope hooks provided on each side board are integrally molded from synthetic resin. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 62-86281 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional one-piece synthetic resin cargo beds have left and right side panels, or so-called side gates, that cannot be opened or closed. This significantly impairs the ease of loading cargo into the cargo bed. Therefore, it is preferable for the side gates to be openable and closable.

[0005] Furthermore, if the side gate were simply separated from the integrally molded cargo bed as a separate part to enable it to be opened and closed, the rigidity of the synthetic resin side gate itself may be insufficient. The side gate comes into contact with the cargo loaded onto the cargo bed and absorbs the load from the cargo. In other words, synthetic resin side gates must be both lightweight and highly rigid.

[0006] Furthermore, the cargo hooks that are integrally molded with the synthetic resin cargo bed have room for improvement in terms of strength and rigidity against the load acting from the rope that is wound around them.

[0007] Therefore, an object of the present invention is to provide a movable gate for a vehicle made of synthetic resin that is both lightweight and highly rigid, and can be equipped with a cargo hook that has excellent strength and rigidity. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems, the movable gate of a vehicle of the present invention is a movable gate made of synthetic resin that is mounted on the vehicle bed and can be opened and closed, and has an upper end having a plurality of ribs arranged horizontally at intervals and at least one through hole formed between a pair of adjacent ribs, a lower end that is rotatably connected to the bed, an upper recess formed near the upper end and recessed toward the inside of the bed, and a lower recess formed between the upper recess and the lower end and recessed toward the outside of the bed, and can be fitted with an attachment that includes a bolt shank that can be placed in the through hole, a nut that is placed between the pair of adjacent ribs and can be tightened to the bolt shank, and a hook that is supported by the bolt shank and the nut, hangs down from the outer surface of the upper end of the movable gate, and can be placed in the recess of the upper recess. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a movable gate for a vehicle made of synthetic resin that is both lightweight and highly rigid, and that can be equipped with a cargo hook that is excellent in strength and rigidity. [Brief explanation of the drawings]

[Figure 6] 1 is a perspective view of an attachment for a cab-over vehicle according to the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0011] A cab-over vehicle according to the present invention will be described below with reference to Figures 1 to 6. Note that the same or corresponding components are designated by the same reference numerals throughout the drawings.

[0012] FIG. 1 is a perspective view showing a cab-over vehicle according to the present invention, viewed from the left rear.

[0013] In Figure 1, the solid arrow Fr indicates the fore-and-aft direction of the cab-over vehicle 1. For ease of explanation, hereinafter the cab-over vehicle 1 will be simply referred to as "vehicle 1." The direction in which the tip of the solid arrow Fr points is the front of the vehicle 1, and the opposite direction is the rear of the vehicle 1. In the following explanation, the right side as viewed from the front of the vehicle 1 will be referred to as the right, and the left side will be referred to as the left.

[0014] As shown in Fig. 1, the vehicle 1 according to this embodiment is a flatbed truck. The vehicle 1 includes a cabin 5 having a driver's seat and a deck 6 disposed behind the cabin 5. The cabin 5 is also called a cab. The deck 6 is capable of carrying cargo and is a so-called loading platform.

[0015] The cabin 5 defines a vehicle interior space in which a driver's seat is located. The cabin 5 includes a pair of openable and closable side doors 7 provided on each of the left and right sides in the vehicle width direction of the vehicle 1, a back panel 11 provided on the back of the cabin 5, and a pair of rear panels 12 provided on each of the left and right sides in the vehicle width direction of the vehicle 1 and disposed between the pair of side doors 7 and the back panel 11.

[0016] The back panel 11 covers the back portion 5 a of the cabin 5 .

[0017] The rear panel 12 covers the rear side 5 b of the cabin 5 .

[0018] The rear side portion 5b of the cabin 5 includes a rear panel 12 corresponding to the exterior, a first inner panel covered by the rear panel 12, and a second inner panel covered by the rear panel 12. The rear panel 12 is disposed outward in the vehicle width direction relative to the first inner panel and the second inner panel. The first inner panel is disposed below the second inner panel.

[0019] The rear side surface 5b of the cabin 5 is provided with a rear pillar reinforcement member extending in the vehicle vertical direction along the rear edge of the opening leading to the interior space through which the side door 7 opens and closes, and a rear pillar inner lower panel disposed closer to the center in the vehicle width direction than the lower region of the rear pillar reinforcement member. The rear pillar inner lower panel is disposed further forward of the first inner panel and lower than the second inner panel.

[0020] In a plan view of the vehicle 1, the rear panel 12, the first inner panel, and the rear pillar inner lower panel define a closed cross section in a lower region of the rear side surface 5b of the cabin 5. The rear side surface 5b of the cabin 5 includes a side brace disposed inside the closed cross section.

[0021] In the lower region of the rear side 5b of the cabin 5, the rear end of the brace is sandwiched between the rear end of the rear panel 12 and the rear end of the first inner panel, and the rear end of the brace, the rear end of the rear panel 12, and the first inner panel are joined together.

[0022] In the upper region of the rear side 5b of the cabin 5, the rear end of the brace is sandwiched between the rear end of the rear panel 12 and the side edge of the back panel 11, and the rear end of the brace, the rear end of the rear panel 12, and the side edge of the back panel 11 are joined together by, for example, spot welding.

[0023] The front end of the brace is joined to the rear end of the rear pillar reinforcement. The front end of the brace may be joined to another vehicle body member disposed on the rear side 5b of the cabin 5 instead of the rear pillar reinforcement.

[0024] The structure of the rear side 5b of the cabin 5 is called the rear pillar 15. In other words, the cabin 5 has the rear pillar 15 disposed at the rear side. Note that, except for the rear panel 12 that contributes to the design of the vehicle 1, the specific configuration of the rear pillar 15 is not limited to the above description.

[0025] The deck 6 includes a flat floor surface portion 21 on which luggage is loaded, and a plurality of movable gates 22a, 22b, 22c that can be opened and closed and that surround the left and right sides and rear of the floor surface portion 21.

[0026] The floor surface portion 21 is a metal sheet metal product. The floor surface portion 21 extends rearward from the back portion 5a of the cabin 5. In a plan view of the vehicle 1, the floor surface portion 21 has a rectangular shape that is long in the front-to-rear direction of the vehicle 1. The floor surface portion 21 is surrounded on all four sides, front, rear, left, and right, by the back panel 11 of the cabin 5 and three movable gates 22a, 22b, and 22c. The left and right side edges of the floor surface portion 21 in the vehicle width direction are supported from below by side members of the chassis that extend in the front-to-rear direction of the vehicle 1.

[0027] The movable gates 22a, 22b, and 22c are also called "gates." The left movable gate 22a is called the left gate or left side gate 22a, the right movable gate 22b is called the right gate or right side gate 22b, and the rear movable gate 22c is called the rear gate or rear gate 22c. The left side gate 22a and the right side gate 22b may be collectively or simply referred to as side gates 22a and 22b. The side gates 22a and 22b are located on the side edge 21a of the deck 6 in the vehicle width direction.

[0028] The side gates 22a, 22b are formed by processing metal sheets. In a side view of the vehicle 1, the side gates 22a, 22b have a rectangular shape that is long in the front-rear direction of the vehicle 1. The side gates 22a, 22b extend in the front-rear direction over the entire length of the floor portion 21.

[0029] The deck 6 is provided with hinge mechanisms provided on the left and right side edges 21a of the floor 21 that support the side gates 22a, 22b rotatably relative to the floor 21. In other words, the side gates 22a, 22b are rotatable about the hinge mechanisms between a closed position and an open position. The left side gate 22a stands perpendicular to the floor 21 in the closed position and defines the left edge of the loading space above the floor 21. The right side gate 22b stands perpendicular to the floor 21 in the closed position and defines the right edge of the loading space above the floor 21.

[0030] The side gates 22a, 22b move to the open position by rotating from the closed position around the hinge mechanism so as to tilt outward or to the side of the vehicle 1. In the open position, the left side gate 22a tilts parallel to the floor surface 21, i.e., horizontally, opening the floor surface 21 to the left. In the open position, the right side gate 22b tilts parallel to the floor surface 21, i.e., horizontally, opening the floor surface 21 to the right. The side gates 22a, 22b may open so as to hang downward from the side edges of the floor surface 21.

[0031] The rear gate 22c is a metal sheet metal product. The rear gate 22c has a rectangular shape that is long in the vehicle width direction when viewed from the rear of the vehicle 1. The rear gate 22c extends in the vehicle width direction across the entire width of the floor portion 21.

[0032] The deck 6 is provided with a hinge mechanism that is provided at the rear edge of the floor 21 and supports the rear gate 22c rotatably relative to the floor 21. In other words, the rear gate 22c is rotatable around the hinge mechanism between a closed position and an open position. In the closed position, the rear gate 22c stands perpendicular to the floor 21 and contacts the rear ends of the left and right side gates 22a and 22b, thereby defining the rear edge of the loading space above the floor 21.

[0033] The rear gate 22c moves to the open position by rotating from the closed position to the outward or rearward position using the hinge mechanism as a base point. In the open position, the rear gate 22c lies parallel to the floor 21, i.e., lies horizontally like the side gates 22a and 22b, opening the floor 21 to the rear. The rear gate 22c may also open by hanging downward from the rear edge of the floor 21.

[0034] The vehicle 1 also includes side lock devices 25a, 25b capable of holding the side gates 22a, 22b in a closed position, rear lock devices 25c1, 25c2 capable of holding the rear gate 22c in a closed position, and a load rest 27 provided on the rear portion 5a of the cabin 5.

[0035] The side lock devices 25a, 25b include a movable handle 31, a latch 32 attached to the handle 31, and a hook 33 provided on the rear pillar 15. The side lock devices 25a, 25b hold the side gates 22a, 22b in the closed position by hooking the latch 32 onto the hook 33.

[0036] The rear locking devices 25c1 and 25c2 include a movable handle 35, a latch 36 attached to the handle 35, and a hook 37 provided on the side gates 22a and 22b. The rear locking devices 25c1 and 25c2 hold the rear gate 22c in the closed position by hooking the latch 36 onto the hook 37.

[0037] The rear gate 22c can be opened by unlocking a pair of left and right rear locking devices 25c1 and 25c2. The left side gate 22a can be opened by unlocking the side locking device 25a and the left rear locking device 25c1. The right side gate 22b can be opened by unlocking the side locking device 25b and the right rear locking device 25c2.

[0038] The load rest 27 can be used as a support against which long cargo such as planks can lean when loading them onto the deck 6.

[0039] Next, the plurality of movable gates 22a, 22b, and 22c will be described. The plurality of movable gates 22a, 22b, and 22c may have a common structure. Therefore, to avoid duplication of explanation, only the left movable gate 22a will be described as a representative.

[0040] FIG. 2 is a first perspective view of a portion of a movable gate of a cab-over vehicle according to the present invention.

[0041] FIG. 3 is a side view of the movable gate of the cab-over vehicle according to the present invention.

[0042] FIG. 4 is a second perspective view of a portion of the movable gate of the cab-over vehicle according to the present invention.

[0043] FIG. 5 is a third perspective view of a portion of the movable gate of the cab-over vehicle according to the present invention.

[0044] 2 and 4 are perspective views showing the front end portion of the movable gate 22a from two different viewpoints outside the deck 6. FIG. 5 is a perspective view showing a part of the upper end portion 41 of the movable gate 22a from a viewpoint inside the deck 6.

[0045] The movable gate 22a of the vehicle 1 according to this embodiment, shown in FIGS. 2 to 5 in addition to FIG. 1, is made of synthetic resin. The movable gate 22a may be a composite material manufactured by adding reinforcing materials such as various fibers and particles, including glass fiber, carbon fiber, and aramid fiber, to synthetic resin. The movable gate 22a is integrally molded, for example, by press molding or injection molding. The movable gate 22a made of synthetic resin is extremely lightweight compared to a typical sheet metal side gate, contributing to a reduction in the weight of the vehicle 1 and thus improving fuel efficiency, and reducing the burden on the user when opening and closing the movable gate 22a. Furthermore, the movable gate 22a made of synthetic resin does not rust like a typical sheet metal side gate, meaning it has excellent corrosion resistance.

[0046] The movable gate 22a is provided on the deck 6 so as to be able to open and close. The movable gate 22a includes an upper end portion 41, a lower end portion 42 rotatably connected to the deck 6, an upper recessed portion 45 provided near the upper end portion 41 and recessed toward the inside of the deck 6 (solid line arrow IS), and a lower recessed portion 46 provided between the upper recessed portion 45 and the lower end portion 42 and recessed toward the outside of the deck 6.

[0047] The movable gate 22a also has a detachable first attachment 48 as a cargo hook.

[0048] Furthermore, the movable gate 22a is provided with a detachable second attachment 49 as a support to be placed under the cargo.

[0049] The movable gate 22a also includes a hinge half 47 that hangs down from the lower end 42 and has a hinge hole 47a in which a pin (shaft) of a hinge mechanism is disposed.

[0050] The upper end portion 41 has a plurality of upper ribs 51 arranged at intervals in the horizontal direction. The plurality of upper ribs 51 extend toward the inside of the deck 6. The upper end portion 41 has a structure in which a plurality of box-shaped spaces that open toward the inside of the deck 6 are arranged continuously in the horizontal direction. In other words, the upper end portion 41 has a pair of upper and lower upper flanges 52, an upper web 53 connecting the pair of upper flanges 52, and a plurality of upper ribs 51 spanning between the pair of upper flanges 52 and the upper web 53. The upper end portion 41 having such a structure enables the movable gate 22a to achieve both high rigidity and light weight against loads acting from cargo placed on the deck 6 and loads acting on the movable gate 22a due to its own weight when opening and closing the movable gate 22a.

[0051] The upper end portion 41 defines a box-shaped space that is open to the inside of the deck 6, while having a flat outer surface 41a on the outside of the deck 6.

[0052] The upper end portion 41 also has at least one upper through-hole 55 provided between a pair of adjacent upper ribs 51. The upper through-hole 55 functions as a weight reduction hole, and also as a mounting portion to which the first attachment 48 can be attached.

[0053] The lower end portion 42 has a plurality of lower ribs 56 (second ribs) arranged at intervals in the horizontal direction. The lower ribs 56 extend toward the outside of the deck 6. The lower end portion 42 has a structure in which a plurality of box-shaped spaces that are open toward the outside of the deck 6 are arranged continuously in the horizontal direction. In other words, the lower end portion 42 has a pair of upper and lower lower flanges 57, a lower web 58 connecting the pair of lower flanges 57, and a plurality of lower ribs 56 spanning between the pair of lower flanges 57 and the lower web 58.

[0054] The lower end 42 defines a box-shaped space that is open to the outside of the deck 6, while having a flat inner surface 42b on the inside of the deck 6.

[0055] The lower end portion 42 may have at least one lower through-hole 59 provided between a pair of adjacent lower ribs 56. The lower through-hole 59 functions as a weight reduction hole and also as a mounting portion to which the second attachment 49 can be attached.

[0056] In a side view of the movable gate 22a (FIG. 5), the upper recess 45 and the lower recess 46 are continuous and form an S shape as shown by the imaginary line α indicated by the two-dot chain line.

[0057] The upper recess 45 has an upper vertical wall 61 that hangs downward inside the deck 6 further than the outer surface 41a of the upper end 41, and an inclined wall portion 62 that extends continuously from the lower end of the upper vertical wall 61 at a downward incline toward the outside of the deck 6.

[0058] The lower recess 46 has an inclined wall portion 62 shared with the upper recess 45, and a lower vertical wall 63 that hangs down continuously from the lower end of the inclined wall portion 62 and connects to the lower end portion 42 outside the deck 6 further than the outer surface 42a of the lower end portion 42.

[0059] The height Hd of the lower recess 46 is higher than the height Hu of the upper recess 45. Note that the height Hd of the lower recess 46 and the height Hu of the upper recess 45 share the height of the inclined wall portion 62, but may be defined as the height of a portion excluding the height of the inclined wall portion 62. The movable gate 22a having such a shape defines a larger loading space near the bottom of the deck 6, i.e., the floor portion 21. Because cargo is generally loaded from the bottom of the deck 6, the deck 6 equipped with the movable gate 22a can load more cargo near the floor portion 21 and also stabilize the cargo.

[0060] As indicated by the imaginary line β in FIG. 5, the outer surface 41a of the upper end portion 41 is positioned closer to the inside of the deck 6 than the outer surface 45a of the upper recess 45 and the outer surface 46a of the lower recess 46. Therefore, when the first attachment 48 is positioned on the outer surface of the movable guard 22b, the movable gate 22a can be fitted with the first attachment 48 that does not protrude further outward from the deck 6 than the upper recess 45 and the lower recess 46, as shown in FIG. 3. This prevents contact between the first attachment 48 and obstacles around the deck 6 or between the user and the first attachment 48. Furthermore, the aesthetic appearance of the areas around the upper end portion 41 and the first attachment 48 is not impaired.

[0061] The upper vertical wall 61 is disposed more inward on the deck 6 than the lower vertical wall 63. The upper vertical wall 61 may be disposed more inward on the deck 6 than the inner surface 63b of the lower vertical wall 63, or may be disposed more outward on the deck 6 than the inner surface 63b of the lower vertical wall 63.

[0062] The inner surface 42b of the lower end portion 42 is disposed further inward on the deck 6 than the inner surface 63b of the lower vertical wall 63. In other words, the inner surfaces of the lower recess 46 and the lower end portion 42 form a terraced or stepped portion on which the second attachment 49 can be placed inside the deck 6.

[0063] FIG. 6 is a perspective view of an attachment for a cab-over vehicle according to the present invention.

[0064] As shown in Figure 6 in addition to Figures 2 to 5, the first attachment 48 of the vehicle 1 in this embodiment comprises a bolt shank 71 that can be placed in the upper through hole 55, a nut 72 that is placed between a pair of adjacent upper ribs 51 and can be tightened to the bolt shank 71, and a hook portion 73 that is supported by the bolt shank 71 and the nut 72, hangs down from the outer surface of the upper end portion 41 of the movable gate 22a, and can be placed in a recess in the upper recess 45.

[0065] 6 is fixed using two upper through-holes 55 of the movable gate 22a. That is, the first attachment 48 includes a plurality of bolt shanks 71, a plurality of nuts 72, and an angle portion 75 with an L-shaped cross section that connects the plurality of bolt shanks 71 and a hook portion 73. The first attachment 48 may be fixed using one upper through-hole 55.

[0066] The angle portion 75 has a first portion 75a that covers the outer surface 41a of the upper end portion 41 of the movable gate 22a, and a second portion 75b that covers the upper flange 52 located below the upper end portion 41 and fits into the recess of the upper recess 45.

[0067] The plate thickness of the first portion 75a in the vehicle width direction is preferably equal to or less than the difference between the outer surface 41a of the upper end portion 41 and the outer surface 46a of the lower recess 46. In other words, the outer surface of the first portion 75a is preferably positioned at the same position as the outer surface 46a of the lower recess 46 in the inward / outward direction of the deck 6, or more inward than the outer surface 46a of the lower recess 46.

[0068] The bolt shank 71 and the nut 72 are preferably housed within the box-shaped space defined by the upper end 41 of the movable gate 22a. By doing so, the bolt shank 71 and the nut 72 that support the first attachment 48 do not protrude into the loading space of the deck 6 from the box-shaped upper end 41 that opens toward the inside of the deck 6. In other words, contact between the first attachment 48 and the cargo is prevented.

[0069] Furthermore, the upper end 41 has a flat outer surface 41a on the outside of the deck 6. Therefore, the first attachment 48 can be placed with the first portion 75a in surface contact with any location on the upper end 41 in accordance with the horizontal pitch of the upper through-holes 55, providing excellent convenience. For example, if the upper end 41 has a flat inner surface on the inside of the deck 6 and has a rib extending to the outside of the deck 6, it is necessary to take the trouble of forming a flat surface at the location where the first attachment 48 is attached, which is cumbersome and reduces convenience and freedom of installation location.

[0070] The hook portion 73 is provided on the second portion 75 b of the angle portion 75 and is disposed in a recess in the upper recess 45 .

[0071] The second attachment 49 includes a rib member 81, a bolt shank 82 extending from the rib member 81 and positionable in the lower through-hole 49, and a nut 83 positioned between a pair of adjacent lower ribs 56 and capable of being tightened onto the bolt shank 82. The second attachment 49 may include a bolt having a threaded hole drilled in the rib member 81, capable of being tightened into the threaded hole of the rib member 81 from outside the movable gate 22a, and capable of having the bolt head positioned between a pair of adjacent lower ribs 56.

[0072] The bolt shank 82 and the nut 83 are preferably contained within the box-shaped space defined by the lower end 42 of the movable gate 22a. In this way, the bolt shank 82 and the nut 83 that support the second attachment 49 do not protrude outside the deck 6 from the box-shaped lower end 42 that opens out toward the outside of the deck 6. In other words, it is possible to prevent obstacles around the deck 6 or users from getting caught on the bolt shank 82 and the nut 83.

[0073] Furthermore, the lower end 42 has a flat inner surface 42b on the inside of the deck 6. Therefore, the second attachment 49 can be placed in surface contact with any location on the lower end 42 according to the horizontal pitch of the lower through-holes 49, which is highly convenient. For example, if the lower end 42 has a flat outer surface on the outside of the deck 6 and has a rib extending to the inside of the deck 6, it is necessary to take the trouble of forming a flat surface at the location where the second attachment 49 is attached, which is cumbersome and reduces convenience and freedom of installation location.

[0074] The upper ribs 51 and the lower ribs 56 of the left movable gate 22a are aligned in the front-to-rear direction of the vehicle 1. The upper ribs 51 and the lower ribs 56 of the right movable gate 22a are also aligned in the front-to-rear direction of the vehicle 1. The upper ribs 51 and the lower ribs 56 of the rear movable gate 22c are aligned in the vehicle width direction.

[0075] The movable gates 22a, 22b, 22c of the vehicle 1 according to this embodiment, which are configured as described above, are made of synthetic resin and include an upper end 41 having a plurality of upper ribs 51 spaced apart horizontally and at least one upper through-hole 55 provided between each pair of adjacent upper ribs 51, a lower end 42 rotatably connected to the deck 6, an upper recess 45 provided near the upper end 41 and recessed into the inside of the deck 6, and a lower recess 46 provided between the upper recess 45 and the lower end 42 and recessed outward from the deck 6. These movable gates 22a, 22b, 22c can be removably fitted with a first attachment 48 which includes a bolt shank 71 which can be placed in the upper through hole 55, a nut 72 which can be placed between a pair of adjacent upper ribs 51 and tightened to the bolt shank 71, and a hook portion 73 which is supported by the bolt shank 71 and the nut 72, hangs down from the outer surface of the upper end portion 41 of the movable gates 22a, 22b, 22c, and can be placed in a recess in the upper recess 45.

[0076] As a result, the movable gates 22a, 22b, and 22c are extremely lighter than typical side gates made of sheet metal, contributing to a reduction in the weight of the vehicle 1 and thereby improving fuel efficiency, and reducing the burden on users when opening and closing the movable gates 22a, 22b, and 22c. Furthermore, the movable gates 22a, 22b, and 22c made of synthetic resin are extremely corrosion-resistant compared to typical side gates made of sheet metal. Furthermore, the movable gates 22a, 22b, and 22c can achieve both high rigidity and light weight against loads acting on the movable gates 22a, 22b, and 22c from cargo loaded on the deck 6 and loads acting on the movable gates 22a, 22b, and 22c due to their own weight when opening and closing the movable gates 22a, 22b, and 22c. In addition, the bolt shaft 71 and nut 72 that support the first attachment 48 are positioned so that the movable gates 22a, 22b, and 22c do not protrude into the loading space of the deck 6 from the box-shaped upper end 41 that opens toward the inside of the deck 6, thereby preventing contact between the first attachment 48 and the cargo.

[0077] Furthermore, the movable gates 22a, 22b, and 22c of the vehicle 1 according to this embodiment include an upper end portion 41 having a plurality of upper ribs 51 extending toward the inside of the deck 6. Therefore, the movable gates 22a, 22b, and 22c are highly convenient because the first attachment 48 can be positioned at any location on the upper end portion 41 according to the horizontal pitch of the upper through-holes 55. Furthermore, the movable gates 22a, 22b, and 22c of the vehicle 1 according to this embodiment include a lower recess 46 that is higher than the height of the upper recess 45. Therefore, the movable gates 22a, 22b, and 22c can load more cargo near the floor portion 21 of the deck 6, and can also stabilize the cargo.

[0078] Furthermore, the movable gates 22a, 22b, and 22c of the vehicle 1 according to this embodiment include an upper end portion 41 having an outer surface 41a that is positioned more inward on the deck 6 than the outer surface 45a of the upper recessed portion 45 and the outer surface 46a of the lower recessed portion 46. Therefore, the movable gates 22a, 22b, and 22c can be fitted with a first attachment 48 that does not protrude further outward on the deck 6 than the upper recessed portion 45 and the lower recessed portion 46, thereby preventing contact between the first attachment 48 and obstacles around the deck 6 or between the user and the first attachment 48. Furthermore, the aesthetic appearance of the areas around the upper end portion 41 and the first attachment 48 is not impaired.

[0079] Furthermore, the movable gates 22a, 22b, 22c of the vehicle 1 according to this embodiment include a lower end portion 42 having a plurality of lower ribs 56 that are arranged at intervals in the horizontal direction and extend outward from the deck 6. Therefore, the movable gates 22a, 22b, 22c are highly convenient because the second attachment 49 can be arranged at any location on the lower end portion 42 according to the pitch of the lower through-holes 99 in the horizontal direction.

[0080] Therefore, the movable gates 22a, 22b, 22c of the vehicle 1 according to the present invention can be made both lightweight and highly rigid, and can be equipped with cargo hooks that are excellent in strength and rigidity.
