[0017] In this embodiment, the storage device 1 is installed under the floor (not shown) of a railway vehicle, and as shown in Figures 1 to 4, the storage device 1 includes a framework 10, a plate portion 20, a door portion 30, a bottom portion 40, a mounting member 50, and a third connecting member 60. In this embodiment, the length of the storage device 1 in the Y-axis direction is approximately 1 m, the length of the storage device 1 in the X-axis direction is approximately 0.7 m, and the length of the storage device 1 in the Z-axis direction is approximately 0.8 m, but of course the lengths are not limited to these.

[0018] In this embodiment, the direction of travel of the railway vehicle is defined as the Y-axis direction, the width direction of the vehicle is defined as the X-axis direction, and the height direction of the vehicle is defined as the Z-axis direction.

[0019] The underfloor of the railway vehicle (not shown) is located on the positive side of the Z axis as viewed from the storage device 1, and the storage device 1 is attached to the underfloor. The storage device 1 is configured to be able to store various electrical devices depending on the type and car number of the railway vehicle. Furthermore, two storage devices 1 can be arranged in the X-axis direction on one vehicle. In this embodiment, they are arranged in an orientation such that the tubular portion 90, which will be described later, is not exposed, but of course, this is not limited to this.

[0020] [Bottom part] In this embodiment, as shown in Figures 2 to 5, the bottom surface portion 40 has a surface parallel to the X-axis direction (first axis direction) and the Y-axis direction (second axis direction). In this embodiment, the bottom surface portion 40 has a rectangular shape with its short sides in the X-axis direction and its long sides in the Y-axis direction, but of course, this is not limited to this and it may also have a rectangular shape with its long sides in the X-axis direction and its short sides in the Y-axis direction, or a square shape. In this embodiment, the bottom surface portion 40 is made of iron, but of course, this is not limited to this and it may be made of, for example, stainless steel (SUS), or may be made of resin, not limited to metal.

[0021] [Itabe] 1 to 4, the plate portion 20 has a top surface portion 21 that faces the bottom surface portion 40 and is connected to the framework 10 (described later), and a plurality of side surface portions 22, 23 that are parallel to the XZ plane (second plane) orthogonal to the Y-axis direction, face each other, and are connected to the framework 10. In the present embodiment, the plate portion 20 is made of iron, but is not limited to this and may be made of, for example, stainless steel (SUS), or may be made of resin instead of metal.

[0022] (Top part) The top surface portion 21 has a top surface 210 that is parallel to the XY plane and faces the bottom surface portion 40. In this embodiment, the top surface 210 is rectangular with its short sides in the X-axis direction and its long sides in the Y-axis direction, but of course this is not limited to this and the top surface 210 may be rectangular with its long sides in the X-axis direction and its short sides in the Y-axis direction, or it may be square. In this embodiment, the thickness of the top surface portion 21 in the Z-axis direction is approximately 1.6 mm, but of course this is not limited to this.

[0023] The top surface portion 21 has hanging fittings 211-214 for attaching the storage device 1 to the underfloor of a railway vehicle on the positive side of the Z axis. In this embodiment, the hanging fittings 211-214 are provided at the four corners of the rectangular top surface portion 21 (see FIGS. 1-3). The hanging fittings 211-214 are connected to the top surface portion 21 by bolts B and nuts N (see FIG. 7). The bolts B penetrate and connect the hanging fittings 211-214 to the top surface portion 21 and the framework 10, as well as between the hanging fittings 211-214 and the top surface portion 21.

[0024] Furthermore, top surface portion 21 has top surface bends 215 extending in the negative direction of the Z axis from the four sides of top surface 210. Top surface bends 215 are shaped like a square when viewed from the Z axis direction (third axis direction), and are located outside (as viewed from the Z axis direction) the size of the outer frame before top surface portion 21 is fitted (when bottom surface portion 40, framework 10, and multiple side surface portions 22, 23 are combined; see FIG. 3). In other words, when top surface portion 21 is combined, top surface bends 215 are located outermost among multiple side surface portions 22, 23, front surface portion 13, and rear surface portion 14 when viewed from the Z axis direction (see FIGS. 1 and 2).

[0025] 2 and 3, the top surface portion 21 has a plurality of top surface connecting holes 21A through which bolts B pass through the top surface portion 21. In this embodiment, the arrangement of the plurality of top surface connecting holes 21A is such that, as viewed from the Z-axis direction, the plurality of sub-frames 12A, 12B, 12D, and 12E (described later) of the framework 10 are provided so that the bolts B can connect the top surface portion 21 and the framework 10 (pass through them in the Z-axis direction).

[0026] In this embodiment, four upper surface connecting holes 21A are provided along the X-axis direction and arranged in four parallel rows, but this is of course not limiting.

[0027] (side part) The side portions 22, 23 are parallel to the XZ plane (second plane) perpendicular to the Y-axis direction, face each other, and are connected to the framework 10. In this embodiment, the thickness of the side portions 22, 23 in the Y-axis direction is approximately 1.6 mm, but is of course not limited to this.

[0028] (First side portion) The first side surface portion 22 has a first side surface 220 that is a surface parallel to the XZ plane, and is connected to the right side surface of the framework body 10 when viewed from the front surface portion 13 side described later (see FIGS. 1 to 4).

[0029] The first side surface portion 22 also has first side surface bent portions 221 extending in the negative direction of the Y axis from three sides of the first side surface 220. The three sides have one side parallel to the X axis direction and facing the bottom surface portion 40, and two sides parallel to the Z axis direction, forming a "U" shape when viewed from the Y axis direction (see FIGS. 2 to 4).

[0030] When viewed from the Y-axis direction, the first side surface bend portion 221 is located outside the size of the outer frame before the first side surface portion 22 is fitted (when the bottom surface portion 40 and the framework 10 are combined, see FIG. 4). In other words, when the first side surface portion 22 is combined, the first side surface bend portion 221 is located outermost among the front surface portion 13, the rear surface portion 14, and the framework 10 when viewed from the Y-axis direction (see FIGS. 1 to 3).

[0031] 2 to 4, the first side surface 220 has a plurality of first side surface connecting holes 22A through which the first connecting member T passes through the first side surface portion 22. In this embodiment, the first connecting member T connects (passes through in the Y-axis direction) the first side surface portion 22 and the framework 10, so that the plurality of first side surface connecting holes 22A are provided at positions where the plurality of sub-frames 12A, 12F, 12H of the framework 10 are connected to the second main frame 11C as viewed from the Y-axis direction, and at positions on the plurality of sub-frames 12A, 12F, 12H where the second main frame 11C is not positioned as viewed from the Y-axis direction (see FIGS. 6 and 7).

[0032] In this embodiment, five of the first side connecting holes 22A are arranged in a row along the X-axis direction, and three sets of five are arranged in a row along the Z-axis direction. Of course, this is not limited to this, and for example, three sets of first side connecting holes 22A may be arranged in a row along the X-axis direction.

[0033] Furthermore, as shown in Figures 1 to 5, the first side surface 220 is connected to a front folding portion 130A (described later) of the front surface portion 13 and a rear folding portion 140A of the rear surface portion 14 by a first connecting member T via the first side surface connecting hole 22A.

[0034] (Second side part) The second side surface portion 23 has a second side surface 230 that is a surface parallel to the XZ plane, and is connected to the left side surface of the framework body 10 when viewed from the front surface portion 13 side described below (see FIGS. 3 and 4).

[0035] The second side surface portion 23 also has second side surface bent portions 231 extending in the positive direction of the Y axis from three sides of the second side surface 230. The three sides have one side parallel to the X axis direction and on the bottom surface portion 40 side, and two sides parallel to the Z axis direction, forming a "U" shape when viewed from the Y axis direction.

[0036] When viewed from the Y-axis direction, the second side surface folding portion 231 is located outside the size of the outer frame before the second side surface portion 23 is fitted (when the bottom surface portion 40 and the framework 10 are combined, see FIG. 4). In other words, when the second side surface portion 23 is combined, the second side surface folding portion 231 is located outermost among the front surface portion 13, the rear surface portion 14, and the framework 10 when viewed from the Y-axis direction (see FIGS. 3 and 4).

[0037] 4, the second side surface 230 has a plurality of second connecting holes 23A through which the first connecting member T penetrates the second side surface portion 23. In this embodiment, the arrangement of the plurality of second side surface connecting holes 23A is such that the first connecting member T connects (penetrates in the Y-axis direction) the second side surface portion 23 to the framework body 10, and the plurality of second side surface connecting holes 23A are provided at positions where the plurality of sub-frames 12E, 12G, 12J of the framework body 10 are connected to the second main frame 11E as viewed from the Y-axis direction, and at positions on the plurality of sub-frames 12E, 12G, 12I where the second main frame 11E is not positioned as viewed from the Y-axis direction (see FIGS. 6 and 7).

[0038] In this embodiment, five of the first side connecting holes 22A are arranged in a row along the X-axis direction, and three sets of five are arranged in a row along the Z-axis direction. Of course, this is not limited to this, and for example, three sets of first side connecting holes 22A may be arranged in a row along the X-axis direction.

[0039] In addition, similar to the first side portion 22, the second side 230 is connected to the front folding portion 130A (described later) of the front portion 13 and the rear folding portion 140A of the rear portion 14 by the first connecting member T via the second side connecting hole 23A.

[0040] In this embodiment, the first side surface 220 and the second side surface 230 are roughly square-shaped, but are not limited to this and may be rectangular in shape with the short side in the X-axis direction and the long side in the Y-axis direction.

The subframe 12A is provided at one end of the first mainframe 11A on the positive side of the Y axis. In this embodiment, the subframe 12A is connected to the mainframe 11 at approximately the center (in the X axis direction) of the subframe 12A.

[0072] The subframe 12A has a plurality of first sub-connecting holes 123A in the first subframe surface 121A for connecting to the upper surface portion 21 with bolts B. The plurality of first sub-connecting holes 123A also serve as through holes for connecting the first subframe surface 121A to the first main frame 11A with the third connecting member 60.

The first connecting member T passes through the first side surface connecting hole 22A and then through the plurality of second sub-corresponding holes 125A. In other words, the first side surface connecting hole 22A and the second sub-corresponding holes 125A are arranged on a straight line in the Y-axis direction.

[0078] The above-described plurality of second sub-connecting holes 124A and plurality of second main connecting holes 113C are used as holes for temporarily fastening the sub-frame 12A and the main frame 11. This is because the main frame 11 and the sub-frame 12 need to be fixed in advance in order to connect them to the plate portion 20, the front surface portion 13, and the rear surface portion 14, which will be described later. In this embodiment, for example, the two second sub-connecting holes 124A and the two second main connecting holes 113C may be fixed in advance with bolts and nuts, rivets, or the like for temporary fastening.

[0079] Furthermore, the subframe 12A may be welded (fillet welded) at the contact points between the first main frame 11A and the second main frame 11C, thereby suppressing rattle when the subframe 12A is fixed to the first main frame 11A and the second main frame 11C.

The multiple first sub-connecting holes 123B provided at the location where the sub-frame 12B and the first main frame 11A are connected are provided so as to be penetrated by the third connecting member 60 in the Z-axis direction, as described above. In this embodiment, a total of six multiple first sub-connecting holes 123B are provided: two on each end side in the X-axis direction and two at the location where the sub-frame 12B is connected to the first main frame 11A, but the number is not particularly limited and may be four or eight.

[0084] The second sub-frame surface 122B has a first cutout portion 124B cut into a U-shape. The first cutout portion 124B is formed at the same position in the X-axis direction as the first sub-connecting hole 123B in the center portion in the X-axis direction, and is fitted to the first main frame 11A. The second sub-frame 12 also has second cutout portions 125B and 126B at both ends in the X-axis direction, and is fitted to the front surface portion 13 and rear surface portion 14, which will be described later.

[0085] Second cutout portion 125B is provided on one end side of subframe 12B in the positive direction of the X axis, and is formed by cutting out a portion of first subframe surface 121B when viewed from the Z axis direction.

Second cutout portion 126B has the same configuration as second cutout portion 125B, but differs in that it is provided on one end side of subframe 12B in the negative direction of the X axis.

[0086] The contact points of the first cutout portions 124B and the first main frame 11A may be welded (fillet welded), which allows for positioning when connecting the upper surface portion 21. Also, rattles can be suppressed when the sub-frame 12B and the first main frame 11A are fixed together.

[0090] The plurality of first sub-connecting holes 123F and the plurality of second main connecting holes 113C provided at the location where the sub-frame 12F and the second main frame 11C are connected (the central portion of the sub-frame 12F in the X-axis direction and the central portion of the second main frame 11C in the Z-axis direction) are provided so as to be penetrated in the Y-axis direction by the third connecting member 60, as described above. In this embodiment, two of the plurality of first sub-connecting holes 123F are provided at the location where the sub-frame 12F and the second main frame 11C are connected.

[0091] Furthermore, when viewed from the Y-axis direction, a plurality of first side surface connecting holes 22A are arranged at the positions where the plurality of second sub-corresponding holes 127F are provided. The first connecting member T passes through the first side surface connecting hole 22A and then through the plurality of second sub-corresponding holes 127F. In other words, the first side surface connecting hole 22A and the second sub-corresponding holes 127F are arranged on a straight line in the Y-axis direction. In this embodiment, three second sub-corresponding holes 127F are provided along the X-axis direction. As shown in FIG. 7 , the three second sub-corresponding holes 127F are provided in the positive and negative directions of the X-axis, centered on a hole that is located at a position overlapping with the second main corresponding hole 113C′ when viewed from the Y-axis direction.

[0093] The above-described plurality of second sub-connecting holes 123F and plurality of second main connecting holes 113C are used as holes for temporarily fastening the sub-frame 12F and the main frame 11. This is because the main frame 11 and the sub-frame 12 need to be fixed in advance in order to connect them to the plate portion 20, the front surface portion 13, and the rear surface portion 14, which will be described later. In this embodiment, for example, the two second sub-connecting holes 123F and the two second main connecting holes 113C may be fixed in advance with bolts and nuts, rivets, or the like for temporary fastening.

[0094] The first sub-frame surface 121F has a first cutout portion 124F cut into a U-shape. The first cutout portion 124F is fitted to the second main frame 11C.

[0095] The second cutout portion 125F is provided on one end side of the subframe 12F in the positive direction of the X axis, and is formed by cutting out a portion of the second subframe surface 122F when viewed from the Z axis direction. When viewed from the Y axis direction, only the first subframe surface 121F is formed on one end side of the subframe 12F in the positive direction of the X axis. The second cutout portion 126F has the same configuration as the second cutout portion 125F, but differs in that it is provided on one end side of the subframe 12F in the negative direction of the X axis.

[0096] Furthermore, the contact points between the subframe 12F and the second main frame 11C (for example, the contact points between the first notch portions 124F and the second main frame 11C) may be welded (fillet welded), thereby preventing rattling when the subframe 12F and the second main frame 11C are fixed together.

[0097] The sub-frame 12G has a configuration substantially similar to that of the above-described sub-frame 12F, but differs in that the sub-frame 12G is provided in approximately the center of the Y-axis of the second main frame 11E.

[0098] As described above, the framework 10 is formed by the main frame 11 parallel to the YZ plane and the sub-frame 12 extending in the X-axis direction, so that the strength of the storage device 1 can be ensured by the framework 10.

[0099] (Front part) The front surface portion 13 has a front surface 130 that is parallel to the YZ plane and is fixed to one end of each of the plurality of sub-frames 12A to 12J that is on the positive side of the X axis, and first openings 131, 132 provided in the front surface 130 (see FIGS. 1 to 5). In this embodiment, the front surface 13 has a rectangular shape with its short sides extending in the Z axis direction and its long sides extending in the Y axis direction. Of course, the shape is not limited to this, and the front surface 13 may also be a rectangular shape with its long sides extending in the Z axis direction and its short sides extending in the Y axis direction, or a square shape.

[0100] The front surface 130 has front surface bent portions 130A extending in the negative direction of the X-axis from the four sides of the front surface 130. The front surface bent portions 130A are shaped like the Japanese character "Kaku" when viewed from the X-axis direction.

[0101] The front folding portion 130A has a plurality of folding holes 130A' that connect to some of the plurality of first side connecting holes 22A. The folding holes 130A' are provided in the front folding portion 130A, which connects the plurality of sub-frames 12A, 12F, and 12H and the plurality of sub-frames 12E, 12G, and 12I to the front portion 13. In this embodiment, three folding holes 130A' are provided along the Z-axis direction, but this is not limited to this and the number may be four or more, or two or less. Furthermore, the folding holes 130A' are not provided on the same line as the sub-frames 12A, 12F, and 12H in the X-axis direction, but they may be provided on the same line.

[0103] As a result, the mated portions become parallel in the XZ plane. Of course, this is not limited to the subframe 12F, but can also be applied to the subframes 12A to 12J. In other words, the mating portion 1300A is formed so as to be mated with the subframes 12A to 12J and become parallel (flush) with the XY and XZ planes. This makes it possible to eliminate gaps when the upper surface portions 21 are connected.

[0104] The first opening 131 is provided on the positive side of the Y axis, has a rectangular annular opening when viewed from the X axis direction, and has a rectangular shape with its short sides in the Z axis direction and its long sides in the Y axis direction.

[0109] The protruding portion 132A is a rectangular ring-shaped portion provided along the rectangular ring-shaped opening, and the flange portion 132B is formed so as to extend outward from the protruding portion 132A (outward from the opening).

[0110] In this embodiment, the front surface portion 13 has the first opening 131 and the second opening 132, but is not limited to this and may have only one of the openings, or may have three or more openings.

[0111] The front surface portion 13 has a plurality of wiring holes 133 provided so as to penetrate in the X-axis direction (see FIGS. 2 to 5). The plurality of wiring holes 133 are holes for passing external wiring 90 when supplying power supplied from the outside to the electrical device 54.

[0112] The front surface portion 13 also has a plurality of hinge portions 134 between the first opening portion 131 and the plurality of wiring holes 133 in the Z-axis direction.

[0113] In this embodiment, two of the hinge portions 134 are provided along the Y-axis direction, and are configured to allow the door portion 30, which will be described later, to rotate about the Y-axis direction. In other words, the door portion 30 opens in the positive direction of the Z-axis. Of course, this is not limitative, and three or more of the hinge portions 134 may be provided.

[0114] The plurality of hinge portions 134 each have a connecting plate 134A that is connected to the door portion 30, and a rotation support portion 134B that is fixed to the front surface portion 13 and supports the connecting plate 134A so that it can rotate freely.

[0115] (rear part) The rear surface portion 14 has a similar configuration to the front surface portion 13, and includes a rear surface 140 that is parallel to the YZ plane and is fixed to one end of each of the sub-frames 12A to 12J on the negative side of the X axis, and a second opening provided in the rear surface 14A (see FIGS. 1 to 5). In this embodiment, the rear surface 140 has a rectangular shape with its short sides extending in the Z axis direction and its long sides extending in the Y axis direction. Of course, the shape is not limited to this, and the rear surface 140 may also be a rectangular shape with its long sides extending in the Z axis direction and its short sides extending in the Y axis direction, or a square shape.

[0116] The rear surface 140 has rear bent portions 140A that extend in the negative direction of the X-axis from the four sides of the rear surface 140. The rear bent portions 140A are shaped like the Japanese character "Kaku" when viewed from the X-axis direction.

[0117] The rear surface bending portion 140A has a plurality of fold-accommodating holes 140A' that connect with some of the above-described plurality of first side surface connecting holes 22A. The plurality of fold-accommodating holes 140A' are provided in the rear surface bending portion 140A, which connects the plurality of sub-frames 12A, 12F, and 12H with the rear surface portion 14. In this embodiment, three fold-accommodating holes 140A' are provided along the Z-axis direction, but this is not limited to this and the number may be four or more, or two or less. Furthermore, the plurality of fold-accommodating holes 140A' are not provided on the same line as the sub-frames 12A, 12F, and 12H in the X-axis direction, but they may be provided on the same line. A similar configuration is also applied to the plurality of sub-frames 12E, 12G, and 12I.

[0118] The rear surface bent portion 140A has a fitting portion 1300B that fits with the above-mentioned sub-frames 12A to 12J. As shown in Fig. 5, the fitting portion 1300B fits with, for example, the second notch portion 126F of the sub-frame 12F.

[0119] As a result, the mated portions become parallel in the XZ plane. Of course, this is not limited to the subframe 12F, but can also be applied to the subframes 12A to 12J. In other words, the mating portion 1300B is formed so as to be mated with the subframes 12A to 12J and become parallel (flush) with the XY and XZ planes. This makes it possible to eliminate gaps when the upper surface portions 21 are connected.

As shown in Fig. 1, the door section 30 has a first door section 30A and a second door section 30B on the front surface section 13 side. In this embodiment, the length of the door section 30 in the Y-axis direction is approximately 600 mm, but is of course not limited to this.

[0122] Door surface 31A has a rectangular shape with its short sides extending in the Z-axis direction and its long sides extending in the Y-axis direction. Fastening fitting 33A is rotatable about the X-axis direction. Fastening fitting 33A has a hook portion 331A provided on the inside of first door section 30A (on the negative side of door surface 31A along the X-axis). The shape of door surface 31A is not limited to the above, and may be a rectangle with its long sides extending in the Z-axis direction and its short sides extending in the Y-axis direction, or a square.

[0123] When closing the first door portion 30A, the closed door state can be maintained by rotating the fastening fitting 33A while pressing the elastic member 80 described later against the flange 131B, and causing the hook portion 331A to abut (press) against the abutment portion 131C.

[0124] [Elastic member] The elastic member 80 is an annular sealing member that is attached to the first door portion 30A and abuts along the first opening 131 when the door is closed. In this embodiment, the elastic member 80 is formed of a packing, but is not limited to this.

Here, the elastic member 80 is in a state where the elastic member 80 is continuously formed, and is a shape formed by adhering or combining a plurality of elastic members into a rectangular ring shape. Of course, this is not limited to this, and the elastic member 80 may be formed seamlessly and integrally from one member (one piece).

[0126] 12, the elastic member 80 has a bottom portion 81 and a bulging portion 82. The bottom portion 81 is provided in a rectangular ring shape along the flange portion 131B and is bonded to the door surface 31A. The bulging portion 82 is provided on the bottom portion 81 and bulges out toward the negative side of the X-axis.

[0127] As described above, when the first door portion 30A is closed, the bulge portion 82 is closed in a state where it is collapsed toward the positive side of the X-axis, thereby creating a sealed state for the first door portion 30A. As shown in Fig. 12, no hollow space is formed in the cross section of the elastic member 80, but a hollow space may be provided in the bulge portion 82, for example. Of course, this is not a limitation, and the cross section of the elastic member 80 as viewed in the Y-axis direction may be rectangular or square (without a convex shape).

[0128] [Mounting parts] Fig. 13 is a perspective view of mounting member 50, Fig. 14 is a perspective view of support member 50A, Fig. 15 is a perspective view of fastener 50C, Fig. 16 is a perspective view showing how fastener 50C is attached, and Fig. 17 is an enlarged view of fastener 50C and support member 50A.

[0129] The mounting member 50 has a support member 50A that supports a plurality of electrical devices 54, and relay connectors 50B that are provided on the support member 50A and that supply power output from an external power source to each of the plurality of electrical devices 54, and is fixed to the framework 10 by fasteners 50C via a mounting support member 50D. In this embodiment, the mounting member 50 is formed of an aluminum frame.

[0130] (support member) The support member 50A has a plurality of column frames 51 that are parallel to the XZ plane and arranged parallel to each other, and a plurality of support frames 52 that are parallel to the Y axis direction and arranged between the plurality of column frames 51, and a plurality of electrical devices 54 have a three-dimensional shape that is attached to each of the plurality of support frames 52 or between the plurality of support frames 52.

[0131] As shown in Figures 13 and 14, the multiple pillar frames 51 include a first pillar frame 51A extending along the Z-axis direction and having a surface parallel to the XZ plane, and a second pillar frame 51B extending along the Z-axis direction and having a surface parallel to the XZ plane, and facing each other in the Y-axis direction.

[0132] 13 and 14, the multiple support frames 52 are provided to connect the first pillar frame 51A and the second pillar frame 51B, and are "C"-shaped frames with an opening in the negative direction of the Y axis, and include, in order from the positive direction of the Z axis, the first support frame 52A, the second support frame 52B, the third support frame 52C, and the fourth support frame 52D. In this embodiment, the multiple support frames 52 are four frames, but of course, the number is not limited to four and may be three or five.

[0133] First support frame 52A has rectangular first hole 522A on the negative side of the Y axis to which fastener 50C (described later) is attached, and circular second hole 521A on the positive side of first hole 522A along the Y axis. First support frame 52A also has rectangular first hole 523A on the positive side of the Y axis to which fastener 50C is attached, and circular second hole 524A on the negative side of first hole 523A along the Y axis.

[0134] Fourth support frame 52D has a rectangular first hole 522D on the negative side of the Y axis to which fastener 50C is attached, and a circular second hole 521D on the positive side of first hole 522D along the Y axis.Fourth support frame 52D also has a rectangular first hole 523D on the positive side of the Y axis to which fastener 50C is attached, and a circular second hole 524D on the negative side of first hole 523D along the Y axis.

[0135] Furthermore, when first support frame 52A and first mounting support member 501D are fixed together by fastener 50C (described later), a portion of fastener 50C can be seen through second hole 521A. Of course, this is not limited to second hole 521A, but the same is true for second hole 524A, 521D, and 524D.

[0136] The second support frame 52B has a first frame 521B that is arranged on the negative side of the first support frame 52A in the Z-axis direction and extends along the Y-axis direction, a second frame 522B that is arranged on the negative side of the Y-axis of the first frame 521B and extends in the Z-axis direction, a third frame 523B that is arranged on the positive side of the Z-axis of the second frame 522B, connected to the second pillar frame 51B and extending along the Y-axis direction, and a fourth frame 524B that is arranged on the negative side of the Z-axis of the second frame 522B, connected to the second pillar frame 51B and extending along the Y-axis direction.

[0137] 13, a first electric device 54A attached to a first frame 521B and a third electric device 54C attached to a third frame 523B and a fourth frame 524B are attached to the second support frame 52B. An example of a mounting method is a method using a DIN rail D, but this is not limited to this, and other methods such as screw fastening are also possible.

[0138] In this embodiment, the DIN rail D is attached to the third support frame 52C, and the second electric device 54B corresponding to the DIN rail D is attached to the DIN rail D. This reduces the number of screws required for fastening, thereby improving work efficiency.

[0139] 13, the third support frame 52C is provided on the negative side of the second support frame 52B in the Z-axis direction, extends along the Y-axis direction, and is provided between (connected to) the first column frame 51A and the second column frame 51B. A second electric device 54B is attached to the third support frame 52C.

[0140] The first electric device 54A, the second electric device 54B, and the third electric device 54C are not particularly limited, but may be, for example, a circuit breaker.

[0141] (Mounting support member) As shown in FIG. 3, the mounting support member 50D is a frame having a first mounting support member 501D and a second mounting support member 502D.

[0142] As described above, the first mounting support member 501D is a frame that is connected to the mounting member connecting holes 115C, 115D, and 115E. Also, as described above, the second mounting support member 502D is connected to the mounting member connecting holes 116C, 116D, and 116E. The mounting support member 50D is fixed to the second main frames 11C, 11D, and 11E with, for example, bolts and nuts.

[0143] The first mounting support member 501D has corresponding holes 5012D that correspond to the first holes 522A provided in the first support frame 52A. Although not shown, the first mounting support member 501D further has corresponding holes that correspond to the second holes 521A, the first holes 523A, and the second holes 524A.

[0144] The second mounting support member 502D also has holes corresponding to the first hole 522D, the second hole 521D, the first hole 523D, and the second hole 524D provided in the fourth support frame 52D.

[0145] Here, "corresponding" means that the structure is such that it penetrates when viewed from the X-axis direction.

[0146] (Relay connector) 13, the relay connector 50B is attached to the support member 50 (third support frame 52C). The relay connector 50B is a connector for supplying power supplied from an external power source via an external wiring 90 to an electrical device 54 via an internal wiring 53. Here, the external wiring 90 is inserted into the interior through a tubular portion 90A provided in the wiring hole 133.

[0147] Here, the tubular portion 90 has a packing (not shown) that is fitted into the wiring hole 133 and has an external wiring hole through which the external wiring 90 is inserted. In this embodiment, the packing has one external wiring hole, and the external wiring hole is configured to pass an external wiring 90 having an outer diameter equal to or larger than the hole diameter of the external wiring hole. This makes it possible to provide a waterproof structure for the hole through which the external wiring 90 passes. In this embodiment, one external wiring hole is provided per packing, but the present invention is not limited to this, and two or more external wiring holes may be provided depending on the number of external wirings 90 to be inserted.

[0148] The relay connector 50B is configured so that an external wiring 90 having a first connector and an internal wiring 53 having a second connector, both of which are formed in the same shape, are fitted and connected. The first connector (not shown) is fitted and connected from one end of the housing of the relay connector 50B, and the second connector (not shown) is fitted and connected from the other end of the housing of the relay connector 50B. For this reason, insertion openings into which the first connector and the second connector are inserted and fitted are formed at one and the other ends of the housing of the relay connector 50B. The insertion openings provided at one and the other ends of the housing of the relay connector 50B open in a direction parallel to the fitting direction of the first connector and the second connector.

[0149] In this embodiment, power is supplied to the electrical device 54 from the combined two external wirings 90 via the relay connector 50B, the first internal wiring 53A, and the second internal wiring 53B. Of course, the number of external wirings 90 is not limited to this and may be three or four. Furthermore, in this embodiment, power is supplied from the first internal wiring 53A to the first electrical device 54A and from the second internal wiring 53B to the second electrical device 54B. However, this is not limited to this and two internal wirings 53 may be connected to the first electrical device 54A and three internal wirings 53 may be connected to the second electrical device 54B. The location of the relay connector 50B is also not limited to the third support frame 52C and may be the second support frame 52B.

[0150] [Fixing device] 13 to 17, fastener 50C is a panel fastener and includes a mounting plate 501C, a bearing member 502C attached to mounting plate 501C, and a pair of hooks 503C. While fastener 50C attached to first hole 522A will be described below, the present invention is not limited to this, and fastener 50C attached to first hole 524A, 522D, 524D is also similar to first hole 522A.

[0151] The mounting plate 501C has a first mounting surface 5011C, which is a flat surface larger than the first hole 522A. The first mounting surface 5011C is a surface parallel to the YZ side surface and to the first support frame 52A. The mounting plate 501C also has a second mounting surface 5012C on the opposite side to the first mounting surface 5011C.

[0152] The bearing member 502C is attached to the first attachment surface 5011C and rotatably supports a pair of hooks 503C (described later). The bearing member 502C is configured to be smaller than the first hole portion 522A and the first attachment hole 1121A when viewed in the X-axis direction.

[0153] The pair of hooks 503C are supported by the above-mentioned bearing member 502C so as to be rotatable about the Z axis. The pair of hooks 503C are configured to be larger than the first hole portion 522A and the first mounting hole 1121A when viewed from the X axis direction. The pair of hooks 503C are held by a coil in a position protruding from the bearing member 502C when viewed from the Z axis direction.

[0154] When fastener 50C is inserted through first hole portion 522A and first mounting hole 1121A, pair of hooks 503C is inserted while being pressed inward by the frames of first hole portion 522A and first mounting hole 1121A.

[0155] When the first mounting surface 5011C comes into contact with the first support frame 52A, the pair of hooks 503C protrude outward due to the force of the spring. As a result, the pair of hooks 503C are engaged with the first mounting support member 501D, thereby fixing the first support frame 52A to the main frame 11. Furthermore, when the first support frame 52A and the first mounting support member 501D are fixed together by the fastener 50C as described above, the pair of hooks 503C can be seen by an operator through the second hole portion 521A (see FIG. 17).

[0156] The pair of hooks 503C may have marks provided at positions visible through the second hole portions 521A. Here, the marks are, for example, red lines or fluorescent paint. This makes it easier for the worker to see the pair of hooks 503C.

[0157] The fastener 50C has a release portion 504C on the second mounting surface 5012C that accommodates the pair of hooks 503C in the bearing member 502C. The pair of hooks 503C are accommodated in the bearing member 502C by rotating the release portion 504C around the X-axis direction. The release portion 504C is rotated using a handle member or the like for rotating the release portion 504C. This allows the first mounting support member 501D and the mounting member 50 to be attached and detached.

[0158] [Third connecting member] As shown in FIGS. 1 to 4, the third connecting member 60 connects the main frame 11 and the sub-frame 12 together.

[0159] In this embodiment, the third connecting member 60 is a rivet, more specifically, a flat head rivet.

[0160] [Second connecting member] As shown in FIG. 9, the second connecting member 70 connects the plurality of first main frames 11A, 11B and the plurality of second main frames 11C, 11D, 11E.

[0161] The connecting points are a plurality of first bent connecting holes 114A and second bent connecting holes 114C, 113D, and 114E, and a plurality of first bent connecting holes 113B and second bent connecting holes 114C, 113D, and 114E. In this embodiment, the second connecting member 70 is a rivet, more specifically, a round head rivet.

[0162] [First connecting member] As shown in FIGS. 1 to 4, the first connecting member T connects the framework body 10 to the first side surface portion 22 and the second side surface portion 23.

[0163] The first connecting members T are inserted through the plurality of first side surface connecting holes 22A to connect the sub-frames 12A, 12F, 12H and the second main frame 11C to the first side surface portion 22.

[0164] Furthermore, the first connecting members T are inserted through the plurality of second side surface connecting holes 23A to connect the sub-frames 12E, 12G, 12J and the second main frame 11E to the second side surface portion 23.

[0165] In this embodiment, the first connecting member T is a rivet, more specifically, a waterproof rivet, which can improve the airtightness of the storage device 1.

[0166] (Method of manufacturing the storage device) Next, a method for manufacturing the container device 1 of this embodiment configured as above will be described.

[0167] The manufacturing method of the storage device 1 in this embodiment includes the steps of assembling the framework 10, attaching the mounting member 50 to the framework 10, and assembling the plate portion 20 and the door portion 30 to the framework 10 to which the mounting member 50 is attached.

[0168] The steps for assembling the framework 10 will be described (see FIGS. 5 to 9). First, the main frame 11 is assembled (see FIGS. 8 and 9). As described above, the main frame 11 is formed by connecting and fixing the first main frames 11A and 11B and the second main frames 11C, 11D, and 11E with the second connecting members 70. This completes the assembly of the main frame 11 as shown in FIG. 8.

[0169] In this case, the first main frames 11A, 11B and the second main frames 11C, 11D, 11E may be connected not only by the second connecting member 70 but also by fillet welding at the points connected by the second connecting member 70.

[0170] Next, the sub-frame 12 is connected to the main frame 11 (see FIGS. 6 and 7). The main frame 11 and the sub-frame 12 are connected (assembled) and fixed by the third connecting member 60, as described above.

[0171] At this time, fillet welding may be performed at the contact points between the main frame 11 and the sub-frame 12.

[0172] Next, the bottom surface portion 40, the front surface portion 13, and the rear surface portion 14 are connected to the main frame 11 and the sub-frame 12 (see FIG. 5). The main frame 11 and the sub-frame 12 are fixed (connected), welded, or adhered to the bottom surface portion 40 with bolts and nuts, or by welding or with an adhesive. The sub-frame 12 (e.g., second cutout portions 125B, 126B) are also welded to the front surface portion 13 and the rear surface portion 14. The bottom surface portion 40 is fixed (connected), welded, or adhered to the front surface portion 13 and the rear surface portion 14 with bolts and nuts, or by welding or with an adhesive. In this way, the framework 10 is assembled.

[0173] Next, the process of attaching the mounting member 50 to the framework 10 will be described (see Figs. 3, 5, and 13-17). First, the mounting support member 50D is attached to the framework 10 inside the framework 10 in the state shown in Fig. 5 (see Fig. 3; however, in this embodiment, the side portions 22 and 23 are not attached at this stage).

[0174] Next, the mounting member 50 is inserted into the framework 10 in the state shown in Fig. 5. There are no particular limitations on the direction (X-axis direction, Y-axis direction, or Z-axis direction) from which the mounting member 50 is inserted into the framework 10, but in this embodiment, the mounting member 50 is inserted from the X-axis direction (front surface portion 13 or rear surface portion 14).

[0175] Next, the mounting member 50 having the electrical device 54, internal wiring 53, and relay connector 50B is attached to the framework 10 via the mounting support member 50D (see FIGS. 3, 13-17). As described above, the mounting support member 50D and the mounting member 50 are fixed at, for example, four locations with the fasteners 50C. In this way, the mounting member 50 is attached via the mounting support member 50D attached to the framework 10.

[0176] Next, the user checks whether a part of the fastener 50C (the pair of hooks 503C) is visible when viewed from the second hole 521A, as shown in Fig. 17. If a part of the fastener 50C (the pair of hooks 503C) is visible when viewed from the second hole 521A, as shown in Fig. 17, it is determined that the mounting member 50 is attached to the mounting support member 50D (framework body 10).

[0177] Next, the cylindrical portions 90A are attached to the plurality of wiring holes 133, and the external wiring 90 is connected to the relay connector 50B via the cylindrical portions 90A.

[0178] Next, the process of assembling the plate portion 20 and the door portion 30 to the framework 10 to which the mounting member 50 has been attached will be described (see FIGS. 1 to 4). First, the first side portion 22 and the second side portion 23 are connected to the framework 10 by the first connecting member T, as described above.

[0179] Next, the top surface portion 21 is connected to the framework 10 to which the first side surface portion 22 and the second side surface portion 23 have been attached, using the bolts B and nuts N, as described above.

[0180] Next, the door section 30 is attached to the front section 13 and the rear section 14. In this way, the plate section 20 and the door section 30 are assembled to the framework 10, and the storage device 1 is assembled (see FIG. 1).

[0181] As described above, it is possible to attach the mounting member 50 to the framework 10 before connecting the plate portion 20 to the framework 10. Therefore, when attaching the mounting member 50 to the framework 10, a worker (user) can reach in from the Y-axis direction to support the mounting member 50 or align it for connection. This allows multiple people to support the mounting member 50 while performing the installation work, even if the mounting member 50 is heavy, thereby improving the efficiency of the installation work for the mounting member 50.

[0182] Since the main frame 11 and the sub-frame 12 are connected by the third connecting member 60, it is possible to eliminate the welding process. This makes it possible to easily fix the main frame 11 and the sub-frame 12 together.

[0183] The first main frames 11A, 11B and the second main frames 11C, 11D, 11E are connected by the second connecting member 70, which makes it possible to reduce the number of welding steps. This makes it possible to easily fix the first main frames 11A, 11B and the second main frames 11C, 11D, 11E together.

[0184] Furthermore, the framework 10 and the plate portions 20 are fixed together with rivets. This reduces the need for welding, making it easier to fix the framework 10 and the plate portions 20 together. The first main frames 11A, 11B and the second main frames 11C, 11D, 11E are also fixed together with rivets in the same manner. This reduces the need for fastening work using bolts and nuts or welding, making it easier to fix the framework 10 and the plate portions 20 together.

[0185] When attaching the mounting member 50 to the mounting support member 50D (framework 10), the worker can easily determine whether the mounting member 50 is securely attached to the mounting support member 50D (framework 10) by checking whether the pair of hooks 503C are visible through the second hole portions 521A. Furthermore, because the mounting member 50 is attached to the mounting support member 50D (framework 10) with fasteners 50C (panel fasteners), the mounting member 50 can be easily attached to the mounting support member 50D (framework 10) without using bolts and nuts.

[0186] Since the framework 10 and the plate portion 20 are connected by the bolts B and the first connecting members T, it is possible to eliminate the welding process. This makes it possible to easily fasten the framework 10 and the plate portion 20 together. Caulking material may also be applied between the framework 10 and the plate portion 20, for example, using a caulking gun. In this case, the material is applied to the areas where the framework 10 and the plate portion 20 come into contact. This improves airtightness. Of course, the method is not limited to a caulking gun, and adhesive tape may also be used.

[0187] The mounting member 50 also has a relay connector 50B for supplying the power output from the external power source to each of the plurality of electrical devices 54. This eliminates the need to wire the external wiring 90 to each of the electrical devices 54, and it is sufficient to simply connect the external wiring 90 to the relay connector 50B, thereby improving the efficiency of wiring work.

[0188] Furthermore, since the mounting member 50 having the electric device 54 with the internal wiring 53 arranged therein is attached to the framework 10, there is no need to perform the work of attaching the electric device 54 inside the framework 10. In other words, since it is possible to attach the electric device 54 and the internal wiring 53 to the support member 50A in advance, and then attach the electric device 54 to the framework 10, the worker can efficiently perform the work of attaching the electric device 54.

[0189] Furthermore, as described above, the mounting member 50 is composed of the column frame 51 and the support frame 52, which increases the degree of freedom in arranging the electric devices 54. For example, a plate parallel to the XZ plane can be attached between the third frame 523B and the fourth frame 524B, and multiple pieces of second electric devices 54C can be arranged on both sides of the plate. In other words, because the mounting member 50 has a three-dimensional structure, the electric devices 54 can be arranged in a three-dimensional manner, and more electric devices 54 can be accommodated.

[0190] Furthermore, as described above, the mounting member 50 is made up of the column frame 51 and the support frame 52, so that a plurality of electrical devices 54 of different sizes can be easily arranged (see FIG. 13).

[0191] The mounting member 50 is formed from an aluminum frame, which allows for weight reduction and cost reduction compared to when a metal plate is used and processed and painted.

[0192] Furthermore, since the elastic member 80 is provided on the door section 30 side and is a single piece, it is possible to easily attach the elastic member 80. Furthermore, since the bulging portion 82 of the elastic member 80 abuts against the flange portion 131B, the door section 30 can be closed easily (compared to, for example, a case where a gasket is provided on the front surface section 13 side and the door bending portion 32A is pressed against the gasket).

[0193] Furthermore, in the storage device 1, the strength of the box can be maintained by the framework 10 described above, and therefore the thickness of the plate portion 20 can be made thin, thereby reducing manufacturing costs.

[0194] <Variation 1> 18 is a schematic vertical cross-sectional view showing the configuration of the door section 300A according to Modification 1. The following mainly describes configurations that differ from the first embodiment, and configurations that are similar to those of the door section 30A of the first embodiment are given the same reference numerals, and descriptions thereof will be omitted or simplified.

[0195] In this modification, front surface portion 13A has a protrusion 1340B that protrudes in the positive direction of the X axis from front surface 130. Protrusion 1340B is provided on the upper side (positive direction of the Z axis) of door portion 300A, and is provided at an angle of approximately 45 degrees diagonally from front surface 130 toward the X axis direction.

[0196] In this modification, the door section 300A has a first hook section 1340A that is roughly L-shaped when viewed in the Y-axis direction. The first hook section 1340A has a first hook surface 1341A provided on the negative side of the X-axis from the door surface 31A, and a second hook surface 1343A that has a first protrusion hole 1342A. The above-mentioned protrusion section 1340B penetrates the first protrusion hole 1342A, engaging the door section 300A and the front surface 13A. Of course, this is not a limitation, and a first protrusion hole may be provided in the protrusion section 1340B, and the first hook section 1340A may be provided to penetrate the first protrusion hole.

[0197] This allows the door section 300A to be closed without using fastening members such as bolts, thereby improving the efficiency of the installation work of the door section 300A.

[0198] <Variation 2> 19 is a schematic vertical cross-sectional view showing the configuration of the door section 300B according to Modification 1. The following mainly describes configurations that differ from the first embodiment, and configurations that are similar to those of the door section 30A of the first embodiment are given the same reference numerals, and descriptions thereof will be omitted or simplified.

[0199] Furthermore, in this modification, door section 300B is provided on the negative side of door surface 31A along the X axis, and has door bending section 320A that engages with first opening 131. Door bending section 320A is provided on the negative side of door surface 31A along the X axis, and is bent so as to engage with (hook onto) first opening 131 (flange section 132A).

[0200] This allows the door section 300B to be closed without using fastening members such as bolts, thereby improving the efficiency of the installation work of the door section 300B.

[0201] <Variation 3> 20 is a schematic vertical cross-sectional view showing the configuration of the door section 300C according to Modification 1. The following mainly describes configurations that differ from the first embodiment, and configurations that are similar to those of the door section 30A of the first embodiment are given the same reference numerals, and descriptions thereof will be omitted or simplified.

[0202] In this modification, opening 131' has a second hook portion 1340B' on the bottom surface portion 40 side that protrudes in the positive direction of the X axis and is L-shaped when viewed from the Y axis direction. Also, handle portion 33A is provided on the top surface portion 21 side. Second hook portion 1340B' protrudes in the positive direction of the X axis and is bent in the positive direction of the Z axis.

[0203] In this modification, the door section 300C has a door bending section 320B having a second protrusion hole 321B provided on the negative side of the X axis from the door surface 31A. The above-mentioned second hook section 1340B' passes through the second protrusion hole 321B, and engages the door section 300C with the front surface section 13B.

[0204] This allows the door section 300C to be closed without using fastening members such as bolts, thereby improving the work efficiency of the installation work of the door section 300C. Furthermore, because the handle section 33A is provided on the top surface section 21 side, it is possible to prevent the door section 300C from closing under its own weight (i.e., preventing it from falling) while the door section 300C is open and work is being carried out.

[0205] <Second embodiment> Next, a second embodiment of the present invention will be described. Fig. 21 is a perspective view of a storage device 1' in the second embodiment, with the door section 30 and the top surface section 21 removed and the side sections 22 and 23 also removed. Fig. 22 is a perspective view of a main frame 11' in the second embodiment. Fig. 23 is a diagram of a first curtain rail section 51R in the second embodiment, where (A) is a cross-sectional view of the first curtain rail section 51R and (B) is a perspective view of the first curtain rail section 51R. Fig. 24 is a perspective view of a support member 50A' and the first curtain rail section 51R in the second embodiment. Below, configurations different from the first embodiment will be mainly described, and configurations similar to those in the first embodiment will be assigned the same reference numerals and their description will be omitted or simplified.

[0206] The storage device 1' of this embodiment differs from the first embodiment in that a curtain rail unit 50R is attached to a main frame 11'. The mounting member 50 includes the curtain rail unit 50R, which extends along the Y-axis direction and is arranged parallel to each other and fixed to the main frame 11' by a fastener B0, a first bolt B1 that is attached to the curtain rail unit 50R and movable in the Y-axis direction, and a first nut N1 that fits with the first bolt B1.

[0207] The main frame 11' also has rail connecting holes 115C', 116C', 115D', 116D', 115E', and 116E' through which the fasteners B0 pass (see FIG. 22).

[0208] In this embodiment, the curtain rail unit 50R is provided between the second main frames 11C' and 11D' of the main frame 11'. In this embodiment, the curtain rail unit 50R includes two curtain rails: a first curtain rail unit 51R and a second curtain rail unit 52R. The first curtain rail unit 51R extends along the Y-axis direction, with one end in the Y-axis direction connected to the second main frame 11D' and the other end in the Y-axis direction connected to the second main frame 11C'. The second curtain rail unit 52R extends along the Y-axis direction, with one end in the Y-axis direction connected to the second main frame 11D' and the other end in the Y-axis direction connected to the second main frame 11C', and faces the first curtain rail unit 51R in the Z-axis direction.

[0209] Here, a method for fixing the curtain rail unit 50R to the main frame 11 will be described using the first curtain rail unit 51R and the second main frame 11D'.

[0210] 21 to 23(A), one end (negative side of the Y axis) of the first curtain rail portion 51R is fixed to the second main frame 11D' via a fastener B0. In this embodiment, the fastener 50C' is a bolt and nut (not shown), but is not limited to this and may of course be a rivet.

[0211] The second main frame 11D' has a rail connecting hole 115D through which the fastener B0 passes. As shown in FIGS. 21 to 23(A), the other end (the positive side of the Y axis) of the first curtain rail section 51R is similarly fixed to the second main frame 11C' via the fastener B0. The second main frame 11C' also has a rail connecting hole 115C' through which the fastener B0 passes. The rail connecting holes 115C' and 115D' are aligned in the Y axis direction.

[0212] That is, the first curtain rail section 51R is fixed to the second main frames 11C' and 11D' by passing the fastener B0 through the first curtain rail section 51R and the rail connecting holes 115C' and 115D'.

[0213] The second curtain rail section 52R is fixed to the main frame 11 in the same manner as the first curtain rail section 51R.

[0214] Next, a method for fastening the curtain rail unit 50R and the support member 50A' will be described. The first curtain rail unit 51R has a first groove 501R on the positive side of the X axis (front surface 13 or support member 50A') through which the first bolt B1 can move. The second curtain rail unit 52R has a second groove 502R on the positive side of the X axis (front surface 13 or support member 50A') through which the first bolt B2 can move.

[0215] The first groove 501R and the second groove 502R extend along the Y-axis direction and are provided at positions that overlap with fastening holes 501A' and 502A', which will be described later, when viewed from the X-axis direction. The head of a first bolt B1 is provided in the first groove 501R so as to be slidable in the Y-axis direction. The head of a second bolt B2 is provided in the second groove 502R so as to be slidable in the Y-axis direction.

[0216] The support member 50A' is a rectangular support plate having a surface parallel to the Y-axis direction and supporting the electrical device 54, and has multiple fastening holes 501A' at the four corners of the rectangle. As shown in Fig. 21 , the multiple fastening holes 501A' are provided at positions that overlap with the first groove portion 501R and second groove portion 502R described above when viewed from the X-axis direction.

[0217] The first bolts B1, B2 can be slid through the multiple fastening holes 501A', and the support member 50A' can be fixed using the first bolts B1, B2 and first nuts N1, N2.

[0218] As described above, because the first bolts B1 and B2 are configured to be movable (slidable), there is no need to increase the precision of the spacing between the multiple fastening holes 501A' compared to when the bolts are fixed in position. This improves the efficiency of the work involved in fixing the support member 50A' (mounting member) to the main frame 11'.

[0219] In this embodiment, the first bolts B1 and B2 are fixed by passing through the multiple fastening holes 501A', but this is not limited to this. For example, the multiple fastening holes 501A' may be cut out in the Y-axis direction. This can further improve the efficiency of the work when fixing.

[0220] Furthermore, in this embodiment, the support member 50A' is a support plate, but of course it is not limited to this and may be the support member 50A (see FIG. 14).

[0221] Furthermore, in this embodiment, the curtain rail unit 50R is provided between the second main frames 11C' and 11D', but this is not limiting, and the curtain rail unit 50R may be provided between the second main frames 11D' and 11E'.

[0222] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and various modifications can be made, and the configurations of the respective embodiments and modifications can be combined. For example, in the present embodiment, the storage device 1 installed under the floor of a railway vehicle has been described, but it may also be installed in, for example, a railway vehicle floor-mounted device, an indoor / outdoor switchboard / distribution box, an equipment room, etc. [Explanation of symbols]
