Summary of the Invention

Problems to be Solved by the Invention

[0005] In the goods transport vehicle of Patent Document 1, a plate-shaped bracket (equipment support frame 33) is arranged in the storage space. Different electrical equipment (50) can be attached to both sides of this bracket (the side facing the base member and the side facing the cover). Furthermore, through holes (35) are formed in the bracket, and by inserting cables through these through holes (35), the electrical equipment (50) attached to each side of the bracket can be connected to each other.

[0006] Incidentally, multiple cables are housed in the aforementioned enclosure. When there are many cables, or when each cable is relatively long, the arrangement of cables within the enclosure tends to become complicated, and there was room for improvement in terms of space utilization efficiency and the efficiency of wiring work. In addition, if multiple cables are not properly held, and the cover is not installed, the cables tend to sag and stick out from the enclosure, which can easily interfere with the work of installing the cover after wiring and with maintenance work on the control device within the enclosure.

[0007] Therefore, there is a need for a transport vehicle equipped with a body that can appropriately accommodate cables and control devices. [Means for solving the problem]

[0008] The goods transport vehicle relating to this disclosure is a goods transport vehicle that transports goods, It comprises a running section equipped with wheels, and a body supported by the running section and forming a storage section for accommodating the article, The vehicle body includes a target wall portion which is a part that constitutes at least a portion of the wall facing the housing portion, The target wall portion comprises a base member, a cover attached to the base member and forming a housing space between itself and the base member for housing a control device, and a bracket attached to the base member and positioned in the housing space. The control device is attached to at least one of the base member and the bracket. With the control device housed in the housing space, a wiring space is formed between the bracket and the base member, where a portion of the cables housed in the housing space are arranged.

[0009] With this configuration, the control device and cables can be properly housed within the storage space between the base member and the cover in the target wall portion of the vehicle body. Furthermore, with this configuration, a wiring space for cables is formed between the bracket and the base member within the housing space. This allows multiple cables to be placed in the wiring space between the bracket and the base member, preventing them from protruding towards the cover. Consequently, cable wiring work and the assembly of the cover onto the base member after the wiring work are made easier.

[0010] Further features and advantages of the goods transport vehicle will become clear from the following description of exemplary and non-limiting embodiments, which will be illustrated with reference to the drawings. [Brief explanation of the drawing]

[Figure 6] Sectional view of the target wall from VI-VI [Modes for carrying out the invention]

[0012] The following describes an embodiment of the goods transport vehicle based on the drawings. As shown in Figure 1, the goods transport vehicle 1 for transporting goods W comprises a running section 4 equipped with wheels 3, and a vehicle body 2 supported by the running section 4 and forming a storage section 9 for storing goods W. In this embodiment, the goods transport vehicle 1 is configured to transport goods W along a predetermined travel path. In this example, goods W are containers for housing semiconductor substrates (FOUP: Front Opening Unified Pod). The goods transport vehicle 1 transports goods W to an processing device that processes the semiconductor substrates. The goods transport vehicle 1 may also transport goods W to a storage rack or the like that stores goods W. In addition to FOUPs, goods W may also be reticle storage containers (so-called reticle pods) for housing reticles, etc.

[0013] As shown in Figures 1 and 2, the running unit 4 is equipped with a plurality of wheels 3. The wheels 3 roll on a running rail R1 provided along the travel path. The running unit 4 is also equipped with a running motor M1 that rotates the wheels 3. At least one of the plurality of wheels 3 is rotationally driven by the running motor M1, so that the running unit 4 travels along the running rail R1. In this example, the running rail R1 is suspended and supported from the ceiling C, and the travel path is formed along the ceiling C. That is, in this example, the goods transport vehicle 1 is an overhead transport vehicle. The goods transport vehicle 1 may be a transport vehicle other than an overhead transport vehicle (for example, a transport vehicle that travels autonomously on the floor, a transport vehicle that travels guided by rails provided on the floor, an automated sorting cart that sorts goods while traveling inside an automated warehouse, a stacker crane, etc.).

[0014] In the examples shown in Figures 1 and 2, a pair of running rails R1 are provided. The running unit 4 also includes guide wheels 41 and auxiliary guide wheels 42. The auxiliary guide wheels 42 abut against the inner sides of the pair of running rails R1. The guide wheels 41 abut against a guide rail R2 that is suspended and supported from the ceiling C. The guide rail R2 is located in branching and merging sections of the running path. The guide wheels 41 are configured to move between a right-guiding position, where they abut the guide rail R2 from the right, and a left-guiding position, where they abut the guide rail R2 from the left. The running unit 4 travels along any running path in branching and merging sections by moving the guide wheels 41 to either the right-guiding position or the left-guiding position.

[0015] The vehicle body 2 is suspended and supported by the running section 4. In this example, the vehicle body 2 is positioned below the running rail R1 (below the running section 4, with the running rail R1 in between). The vehicle body 2 holds the article W and transfers the article W to the transport location. In this embodiment, the vehicle body 2 is equipped with a holding section 8 for holding the article W. The holding section 8 suspends and supports the article W. The holding section 8 is also configured to be able to move up and down relative to the running section 4. When the running section 4 is running, the holding section 8 is positioned in the raised position. When transferring the article W to the transport location, the holding section 8 is positioned in the lowered position. The raised position is the position where the article W held by the holding section 8 is stored in the storage section 9. The lowered position is a position lower than the raised position, and is the position where the holding section 8 receives the article W placed at the transport location or hands over the article W to the transport location. In this example, the vehicle body 2 is equipped with a lifting section 16. The lifting unit 16 comprises a drum, a belt wound around the drum with a holding part 8 connected to its end, and a lifting motor M2 (Figure 1) that rotates the drum and drives the belt. The lifting unit 16 raises and lowers the holding part 8 between the raised position and the lowered position as described above by rotating the drum with the drive of the lifting motor M2.

[0016] Hereinafter, the width direction of the vehicle body 2 of the article carrier 1 (the direction in which the pair of traveling rails R1 are arranged) is defined as the first direction X, the vertical direction along the up-and-down direction is defined as the second direction Z, and the direction orthogonal to the width direction in the up-and-down view, that is, the front-back direction of the vehicle body of the article carrier 1 is defined as the third direction Y. Further, one side of the first direction X is defined as the first side X1 of the first direction, the other side of the first direction X is defined as the second side X2 of the first direction, the rear side of the vehicle body 2 in the third direction Y is defined as the first side Y1 of the third direction, and the opposite side (the front side of the vehicle body 2) is defined as the second side Y2 of the third direction.

[0017] As shown in FIGS. 1 to 3, the vehicle body 2 includes a target wall portion 10 that forms at least a part of the wall facing the storage portion 9. In the present embodiment, the target wall portion 10 is provided so as to be adjacent to one side of the third direction Y with respect to the storage portion 9. Further, the target wall portion 10 is arranged so as to cover the storage portion 9 from one side in the third direction Y. In this example, the target wall portion 10 is arranged on the first side Y1 of the third direction (the rear side of the vehicle body 2) with respect to the storage portion 9. And when the article W is stored in the storage portion 9, the target wall portion 10 overlaps the article W in the third direction Y view.

[0018] As shown in FIGS. 1 to 3, the vehicle body 2 includes a cover portion 14. The cover portion 14 is provided so as to cover the storage portion 9 from both sides and the upper side in the third direction Y. Further, the cover portion 14 is provided so as to cover the lifting portion 16 and the holding portion 8 at the raised position. In this example, the cover portion 14 is arranged below the traveling rail R1.

[0019] The cover part 14 includes a first cover part 14a arranged on the first side Y1 (rear side of the vehicle body 2) in the third direction with respect to the accommodation part 9, a second cover part 14b arranged on the second side Y2 (front side of the vehicle body 2) in the third direction with respect to the accommodation part 9, and a connecting part 20 that connects the first cover part 14a and the second cover part 14b. The connecting part 20 connects the upper end part of the first cover part 14a and the upper end part of the second cover part 14b. In the illustrated example, the connecting part 20 is a member formed in a rectangular shape when viewed in the vertical direction. In this example, the first cover part 14a covers the accommodation part 9 from the first side Y1 in the third direction, the second cover part 14b covers the accommodation part 9 from the second side Y2 in the third direction, and the connecting part 20 covers the accommodation part 9 from above. In addition, in this example, the cover part 14 is not arranged on both outer sides in the first direction X (width direction of the vehicle body 2) with respect to the accommodation part 9 (FIGS. 2 and 3).

[0020] As shown in FIGS. 1 to 6, the target wall part 10 includes a base member 11, a cover 12 attached to the base member 11 and forming an accommodation space S for accommodating the control device H between the cover 12 and the base member 11, and a bracket 5 attached to the base member 11 and arranged in the accommodation space S. The control device H controls the operations of the article transfer vehicle 1 (such as running operation and article W transfer operation). In the present embodiment, the target wall part 10 is a first cover part 14a that covers the accommodation part 9 from the first side Y1 (rear side of the vehicle body 2) in the third direction. Therefore, the first cover part 14a includes the base member 11, the cover 12, and the bracket 5. In addition, the target wall part 10 further includes a bottom part 17 that connects the lower end part of the base member 11 and the lower end part of the cover 12.

[0021] As shown in Figures 3 to 5, the base member 11 is formed in a plate shape and is arranged to extend in the second direction Z (vertical direction) and the first direction X (width direction) perpendicular to the second direction Z. The base member 11 of the target wall portion 10 (here, the first cover portion 14a) is arranged to cover the housing portion 9 from the third direction first side Y1. The base member 11 is also arranged to face the surface of the article W housed in the housing portion 9 that faces the third direction first side Y1. In this example, as shown in Figures 3 to 6, the base member 11 is provided with a stepped portion 15. The stepped portion 15 is a stepped portion of the base member 11 along the second direction Z (vertical direction). Due to this stepped portion 15, the region from the stepped portion 15 to the first direction first side X1 of the base member 11 is arranged in the third direction first side Y1 relative to the region from the stepped portion 15 to the first direction second side X2. In the illustrated example, the base member 11 is formed in a rectangular shape when viewed in the third direction Y. The stepped portion 15 is formed on the first side X1 of the first direction X, rather than the center of the base member 11 in the first direction X. The upper end of the base member 11 is connected to the connecting portion 20. More specifically, the upper end of the base member 11 is fixed to the end of the connecting portion 20 on the first side Y1 of the third direction.

[0022] As shown in Figure 2, the cover 12 is positioned to cover the base member 11 from the third direction, the first side Y1. The cover 12 is configured to be removable from the base member 11. In this example, the cover 12 is attached to both ends of the base member 11 in the first direction X and to the bottom 17 in a removable manner. The housing space S is the space enclosed by the cover 12, the base member 11, and the bottom 17 when the cover 12 is attached. Various electrical equipment and devices, including the control device H, can be housed in this housing space S. In the examples of Figures 2 and 6, the cover 12 is formed in a curved shape that bulges outwards in the third direction, the first side Y1. The bottom 17 is also curved in a shape that bulges outwards in the third direction, the first side Y1, corresponding to the shape of the cover 12.

[0023] As shown in Figures 3, 4, and 6, the bracket 5 comprises a plate-shaped portion 21 and a mounting portion 23 attached to the base member 11, with the plate-shaped portion 21 positioned along the base member 11. The bracket 5 also includes a third fixing portion 26 fixed to the base member 11. In this example, the plate-shaped portion 21 is formed to align with the second direction Z (vertical direction) and the first direction X (width direction) when the bracket 5 is attached to the base member 11, so that the plate-shaped portion 21 is positioned parallel to the surface of the base member 11 facing the front side (third direction first side Y1). In this embodiment, the plate-shaped portion 21 is positioned spaced apart from the base member 11 in the third direction first side Y1 (the side where the cover 12 is positioned). The plate-shaped portion 21 is also positioned to overlap the stepped portion 15 of the base member 11 when viewed in the third direction Y. The mounting portion 23 is the part that is bent relative to the plate-shaped portion 21 and attached to the base member 11. In this example, as shown in Figure 6, the mounting portion 23 is formed by bending from the end of the plate-shaped portion 21 on the first side X1 in the first direction toward the second side Y2 in the third direction (the side where the base member 11 is located). Here, the mounting portion 23 is attached to the base member 11 via the third fixing portion 26. Note that the plate-shaped portion 21 does not have to be arranged parallel to the base member 11 as described above, and may be arranged in a position that is inclined relative to the base member 11. Also, the plate-shaped portion 21 may be formed in a shape that bulges toward the first side Y1 in the third direction, for example. Thus, the orientation and shape of the plate-shaped portion 21 can be changed as needed. Note that the plate-shaped portion 21 may be a mesh-like member, in which case control equipment or the like can be attached to the mesh-like member. Furthermore, by utilizing the mesh portion, it is possible to support one or more cables 7 on the mesh-like member (plate-shaped portion 21) using cable ties or the like.

[0024] In this embodiment, as shown in Figures 4 and 6, the third fixing portion 26 is provided at the end of the bracket 5 on the first side X1 in the first direction. The third fixing portion 26 is a part that is bent from the mounting portion 23 and fixed to the base member 11. In this example, the third fixing portion 26 is formed by bending from the end of the mounting portion 23 on the second side Y2 in the third direction to the first side X1 in the first direction. The third fixing portion 26 is a plate-shaped member formed along the surface of the base member 11 facing the front side (first side Y1 in the third direction). The third fixing portion 26 is fixed by a fastening member while in contact with the surface of the base member 11 facing the front side. In the example of Figure 4, multiple third fixing portions 26 are provided, each separated in the second direction Z (up and down direction). In the illustrated example, the plate-shaped portion 21, the mounting portion 23, and the third fixing portion 26 are formed integrally, but they do not necessarily have to be formed integrally.

[0025] Here, the control device H is attached to at least one of the base member 11 and the bracket 5. In this embodiment, as shown in Figures 3 to 6, the control device H is attached to both the base member 11 and the bracket 5. The control device H also includes at least one control device. In this example, the control device H includes a plurality of control devices (in the illustrated example, the first control device H1 to the third control device H3). In this embodiment, the control devices are attached to at least one of the surface of the plate-shaped portion 21 that faces the base member 11 (the second surface 21b of the plate-shaped portion) and the base member 11. Here, the first control device H1 is attached to the base member 11, and the second control device H2 and the third control device H3 are attached to the bracket 5. More specifically, the first control device H1 is fixed to the region of the second side X2 in the first direction relative to the stepped portion 15 on the surface of the base member 11 facing the first side Y1 in the third direction. Furthermore, the first control device H1 is positioned on the second side X2 in the first direction relative to the bracket 5 (here, the plate-shaped portion 21). The second control device H2 is fixed to the surface of the plate-shaped portion 21 facing the second side Y2 in the third direction (second surface 21b of the plate-shaped portion). The second control device H2 is also positioned in the gap between the plate-shaped portion 21 and the base member 11 so as to be spaced apart from the base member 11 in the third direction Y. The third control device H3 is fixed to the surface of the plate-shaped portion 21 facing the first side Y1 in the third direction (first surface 21a of the plate-shaped portion). Thus, in this example, multiple control devices can be attached to the surface of the base member 11 facing the first side Y1 in the third direction, the first surface 21a of the plate-shaped portion, and the second surface 21b of the plate-shaped portion. The control devices include control units that control the travel motor M1 and lifting motor M2 of the material transport vehicle 1, control boards for various sensors, motor drivers, sensor drivers, etc. Furthermore, although this example shows a configuration with three control devices, the number of control devices may be one, two, or three or more. Also, one control device may be fixed to both the base member 11 and the bracket 5. In the illustrated example, in addition to the third control device H3, other devices 31 different from control devices are also fixed to the first surface 21a of the plate-like portion.

[0026] As shown in Figures 3, 4, and 6, in this embodiment, the target wall portion 10 further comprises a bridge member 6 arranged to extend along a first direction X. The bridge member 6 is positioned adjacent to the bracket 5 on the second side X2 in the first direction and connects the end of the bracket 5 (specifically, the plate-shaped portion 21) on the second side X2 in the first direction to the end of the base member 11 on the second side X2 in the first direction. The bridge member 6 is also positioned spaced apart from the base member 11 in a third direction Y (Figure 6). In this example, the bridge member 6 connects the upper end (one end in the second direction Z) and the end on the second side X2 in the first direction of the plate-shaped portion 21 to the end of the base member 11 on the second side X2 in the first direction.

[0027] As shown in Figures 4 and 6, the bridge member 6 comprises a first fixing portion 24 fixed to the bracket 5 and a second fixing portion 25 fixed to the base member 11. The first fixing portion 24 and the second fixing portion 25 are spaced apart in the first direction X. The second fixing portion 25 is positioned on the second side X2 of the first direction relative to the first fixing portion 24. In this example, the bridge member 6 further comprises a bridge body 33, a bridge inclined portion 34, a bridge rib portion 35, and a bridge mounting portion 32. The bridge member 6 is formed in a long strip (plate) shape in the first direction X by connecting the bridge body 33 and the bridge inclined portion 34 side by side along the first direction X.

[0028] The first fixing portion 24 is formed continuously from the end of the bridge body 33 on the first side X1 in the first direction, and connects the end of the plate-shaped portion 21 on the second side X2 in the first direction to the bridge body 33. In the illustrated example, the first fixing portion 24 is formed by bending from the end of the bridge body 33 on the first side X1 in the first direction, and is fixed to the plate-shaped portion 21 via a fastening member. Here, the bridge body 33 is a strip-shaped member extending in the first direction X, and is arranged parallel to the surface of the base member 11 facing the first side Y1 in the third direction. The bridge inclined portion 34 is formed continuously from the end of the bridge body 33 on the second side X2 in the first direction. The bridge inclined portion 34 is a strip-shaped member that inclins toward the second side Y2 in the third direction (the side of the base member 11) as it moves toward the second side X2 in the first direction. The bridge mounting portion 32 is formed continuously from the end of the bridge inclined portion 34 on the second side X2 in the first direction. In the illustrated example, the bridge body 33 has a plurality of openings 37 that penetrate in the third direction Y. In addition, a plurality of arc-shaped first grooves 36 are formed at the upper end of each opening 37.

[0029] The second fixing portion 25 is formed continuously from the end of the bridge inclined portion 34 on the second side X2 in the first direction, and connects the bridge inclined portion 34 to the end of the base member 11 on the second side X2 in the first direction. In the illustrated example, the second fixing portion 25 is bent from the end of the bridge inclined portion 34 on the second side X2 in the first direction so as to follow the base member 11. The second fixing portion 25 is then fixed by a fastening member while in contact with the surface of the base member 11 facing the second side Y2 in the third direction. In this example, the bridge body 33 and the bridge inclined portion 34 overlap the first control device H1 when viewed in the third direction Y, and are positioned spaced apart from the first control device H1 in the third direction Y (Figure 4).

[0030] The bridge rib portion 35 is formed by bending from the upper end of the bridge body 33 toward the third direction, first side Y1 (the side of the cover 12). The bridge rib portion 35 has a second groove portion 38 that is cut out in the vertical direction and in the third direction, first side Y1. In the illustrated example, the bridge rib portion 35 is formed in a long plate shape in the first direction X. Multiple second groove portions 38 are formed so as to be aligned in the first direction X.

[0031] As shown in Figures 4 to 6, with the control device H housed in the housing space S, a wiring space E is formed between the bracket 5 and the base member 11, where a portion of the cable 7 housed in the housing space S is placed. Here, the cable 7 is connected to the control device H. The cable 7 is, for example, a communication cable or a power supply cable. In this embodiment, at least a portion of the wiring space E is formed in the area enclosed by the plate-shaped portion 21, the base member 11, and the control equipment. Note that the "enclosed area" is not limited to an area completely enclosed (covered) by such members, etc., but also includes an area that is not partially enclosed. In this example, the wiring space E is the space (gap) formed between the plate-shaped portion 21 and the base member 11. Furthermore, the wiring space E is the space enclosed by the second surface 21b of the plate-shaped portion, the stepped portion 15 of the base member 11 and the surface facing the third direction first side Y1, and the first control equipment H1 fixed to the base member 11. Furthermore, when the second control device H2 is attached to the second surface 21b of the plate-like portion, the wiring space E is the space formed between the second control device H2 and the base member 11. Therefore, in this case, at least a portion of the wiring space E is also enclosed by the second control device H2, in addition to the above. In the examples of Figures 5 and 6, the wiring space E can also be described as the space formed between the stepped portion 15 and the first control device H1. As shown in Figures 5 and 6, one or more cables 7 can be accommodated in the wiring space E. For example, the end of the wiring space E on the second side X2 in the first direction is not completely enclosed by the first control device H1, but is open in the first direction X. Therefore, in the wiring space E, multiple cables 7 (dashed lines) connected in the second direction Z (vertical direction) on the first control device H1 can be accommodated using this opening. Furthermore, when accommodating multiple cables 7 wired from the first control device H1, the lower end of the wiring space E can be positioned to correspond to the lower end of the first control device H1.

[0032] In this example, the housing space S, surrounded by the base member 11, the cover 12, and the bottom 17, has multiple spaces (first space F1 to fourth space F4) separate from the wiring space E. As shown in Figures 5 and 6, the first space F1 is formed between the first control device H1 and the bridge member 6. Here, the first space F1 is the space surrounded by the wiring space E and the third space F3 and fourth space F4, which will be described later.

[0033] The second space F2 is formed between the second surface 21b of the plate-like portion and the region X1 on the first side in the first direction relative to the stepped portion 15 of the base member 11. The second space F2 is also the space adjacent to the wiring space E on the first side in the first direction relative to the wiring space E. The third space F3 is formed between the upper end of the base member 11 and the upper end of the cover 12. The third space F3 is also the space above the wiring space E, the second space F2, and the fourth space F4 described later. In the example shown in Figures 3 to 5, the target wall portion 10 (here, the first cover portion 14a) further includes a support plate 13. The support plate 13 is a plate-like member that follows a horizontal plane. The support plate 13 is fixed in a cantilevered manner to the base member 11 at a position above the bracket 5 and the first control device H1. In the illustrated example, the third space F3 is the space above the support plate 13 in the accommodation space S.

[0034] The fourth space F4 is formed in the accommodation space S on the third direction, first side Y1, relative to the bracket 5 and bridge member 6. In the illustrated example, the fourth space F4 is the space surrounded by the bracket 5, bridge member 6, bottom 17, and support plate 13.

[0035] In this example, one or more cables 7 can be housed in the wiring space E along the second direction Z (vertical direction), and the housed cables 7 can be supported by the support plate 13. Specifically, a connector 43 (Figure 5) can be placed on the support plate 13 and connected to the wiring located in the third space F3. Therefore, for example, by housing multiple cables 7 connected to the control boards of control equipment (here, the first control equipment H1 to the third control equipment H3) together in the wiring space E, and connecting each cable 7 to the corresponding connector 43 attached to the support plate 13, it is easier to avoid the cables 7 interfering with the control equipment, and it is also easier to avoid the multiple wires connected via the connector 43 becoming entangled with each other. Furthermore, by housing multiple cables 7 in the wiring space E, it is possible to prevent these cables 7 from protruding beyond the plate-shaped portion 21 of the bracket 5 towards the cover 12. Furthermore, since the cables 7 can be accommodated using the stepped section 15, it is easier to avoid, for example, some of the cables 7 moving over the stepped section 15 to the second space F2 while the goods transport vehicle 1 is in motion, and as a result, it is less likely that these cables 7 will be arranged haphazardly.

[0036] Furthermore, for example, by routing the cable 7 connected to the third control device H3 and other devices 31 attached to the first surface 21a of the plate-like portion along the bridge member 6, it becomes easier to avoid the cable 7 interfering with the first control device H1 or becoming entangled with other cables 7 connected to the first control device H1 or the second control device H2. When routing the cable 7 to the bridge member 6, the opening 37 formed in the bridge body 33, the first groove 36, and the second groove 38 formed in the bridge rib portion 35 can be utilized. Specifically, when arranging the cable 7 along the bridge body 33 and securing it together with the bridge body 33 using cable ties, the cable 7 can be firmly fixed by the bridge member 6 by passing the cable tie through the opening 37 and hooking it into the first groove 36 and the second groove 38. Therefore, the cable 7 arranged along the bridge member 6 can be prevented from bending and sticking out towards the cover 12. The ends of the cables 7 arranged along the bridge member 6 may, for example, be positioned on the side of the support plate 13 to connect to a connector 43 attached to the support plate 13.

[0037] Furthermore, one or more cables 7 can be accommodated in the second space F2. For example, by accommodating a different type of cable 7 (such as a cable 7 connected to a different control device) in the second space F2 than the cable 7 accommodated in the wiring space E, less related cables 7 can be accommodated separately. In addition, because a stepped portion 15 is provided, it is easier to avoid the cables 7 accommodated in the second space F2 and the wiring space E moving and becoming entangled with each other while the goods transport vehicle 1 is in motion. Furthermore, one or more cables 7 can also be accommodated in the first space F1. In this case, the bridge member 6 makes it possible to prevent the cable 7 placed in the first space F1 from extending beyond the bridge member 6 and protruding towards the cover 12. Here, in the example of Figures 3 and 4, a connecting member 27 is provided that connects the lower end of the plate-shaped portion 21 and the end on the second side X2 in the first direction to the end on the second side X2 in the first direction of the base member 11. The connecting member 27 is oriented along the first direction X and is positioned parallel to the bridge member 6. Furthermore, the connecting member 27 is spaced apart from the first control device H1 in the third direction Y. Therefore, by using the connecting member 27 as a retaining member in addition to the bridge member 6, it is possible to more effectively prevent the cable 7 housed in the first space F1 from protruding beyond the bridge member 6 (and the connecting member 27) towards the cover 12.

[0038] Furthermore, the third space F3 can accommodate other cables connected to the cables 7 wired from each control device (first control device H1 to third control device H3). It also prevents these cables from extending beyond the support plate 13 into the wiring space E or the first space F1. In addition to cables and control devices H, other necessary equipment can be placed in the first spaces F1 to the fourth spaces F4 as needed.

[0039] As shown in Figures 2 and 3, in this example, the second cover portion 14b is configured to include a base member 11, a cover 12, and a bottom portion 17, similar to the first cover portion 14a (Figures 2 and 3). On the other hand, in this example, the second cover portion 14b is not designated as the target wall portion 10, and therefore does not include the bracket 5 or bridge member 6 described above. However, it is also possible to designate the second cover portion 14b as the target wall portion 10, in which case the second cover portion 14b can have the same configuration as the first cover portion 14a described above. Furthermore, the connecting portion 20 can also be designated as the target wall portion 10. Moreover, there may be multiple target wall portions 10. For example, the connecting portion 20, the first cover portion 14a, and the second cover portion 14b can each be designated as the target wall portion 10.

[0040] [Other Embodiments] Next, other embodiments of the goods transport vehicle 1 will be described.

[0041] (1) In the above embodiment, the control device H was described as being able to be attached to both the base member 11 and the bracket 5 as an example, but the invention is not limited to this. For example, the control device H may be able to be attached to only one of the base member 11 and the bracket 5.

[0042] (2) In the above embodiment, the bracket 5 was described as having a plate-shaped portion 21 as an example, but it is not limited to this. For example, the bracket 5 does not have to have a plate-shaped portion 21. In this case, the bracket 5 can use a member that replaces the plate-shaped portion 21.

[0043] (3) In the above embodiment, a configuration in which the first direction X is the width direction of the vehicle body 2, the second direction Z is the vertical direction, and the third direction Y is the front-rear direction of the vehicle body of the goods transport vehicle 1 was described as an example, but the invention is not limited to this. For example, the first direction X can be the front-rear direction of the vehicle body of the goods transport vehicle 1, the second direction Z can be the vertical direction, and the third direction Y can be the width direction of the vehicle body 2. In this case, the cover portion 14 is arranged so as to cover the storage portion 9 from the width direction of the vehicle body 2. Therefore, the target wall portion 10 is arranged so as to cover the storage portion 9 from at least one side in the width direction. Thus, the position in which the target wall portion 10 is arranged can be changed as needed.

[0044] (4) In the above embodiment, the third fixing portion 26 was described as being provided at the end of the bracket 5 on the first side X1 in the first direction, but the embodiment is not limited to this. For example, the third fixing portion 26 may be provided at a location other than the end of the bracket 5 on the first side X1 in the first direction.

[0045] (5) The configurations disclosed in each of the embodiments described above can be applied in combination with configurations disclosed in other embodiments (including combinations of embodiments described as other embodiments), as long as no inconsistencies arise. With regard to other configurations, the embodiments disclosed in this specification are merely illustrative in all respects. Therefore, various modifications can be made as appropriate without departing from the spirit of this disclosure.
