Description

[Technical Field]

[0001] The present invention relates to a railway vehicle having a partition panel facing an aisle of a platform and a ceiling panel. [Background technology]

[0002] Generally, on the deck of a railway car, spaces used for on-board equipment such as a multipurpose room, machinery room, toilet, and washbasin are partitioned off from the aisle by partition panels. In the railway car described in Patent Document 1, the spaces used for on-board equipment are partitioned by assembling a compartment structure on the car that has been separated from on-board work performed on the car body and made into an out-worked compartment.

[0003] The applicant has conventionally installed partition panels on the floor to separate the space used for in-vehicle equipment. There are two methods for installing the partition panels: one is to first fix the ceiling panel to the ceiling side, and then fix the partition panel to the ceiling panel (conventional installation method 1), and the other is to first fix the partition panel to the ceiling side, and then fix the ceiling panel to the partition panel (conventional installation method 2).

[0004] Figure 7(A) is a partial cross-sectional schematic diagram showing the fixing structure of the partition panel and ceiling panel related to conventional installation method 1, and Figure 7(B) is a partial cross-sectional schematic diagram showing the fixing structure of the partition panel and ceiling panel related to conventional installation method 2.

[0005] According to conventional installation method 1, as shown in FIG. 7(A), the ceiling panel 32 is fixed at its outer end in the carbody width direction by a bolt 80 via a spacer 81 to a ceiling frame 40 supported by the roof structure. A connecting member 82 having an L-shaped cross section is fastened at one straight portion between the ceiling panel 32 and the head of the bolt 80. The other straight portion of the connecting member 82 bends downward in the carbody height direction from the inner end in the carbody width direction of the one straight portion. The partition panel 31 is joined to a receiving member 84 at the rear surface on the outer side in the carbody width direction of the upper end. The receiving member 84 is fastened to the other straight portion of the connecting member 82 by a bolt 86 via a liner plate 85. As a result, the partition panel 31 is positioned inward of the outer end of the ceiling panel 32 in the carbody width direction and is installed a predetermined distance below the ceiling panel 32. A gap S8 is formed between the ceiling panel 32 and the upper end of the partition panel 31. However, the bolt 80 is blocked from the gap S8 by the connecting member 82 and the receiving member 84. Therefore, if it is desired to remove the ceiling panel 32, it is necessary to first remove the partition panel 31 by removing the bolt 86 from the gap S8, and then remove the ceiling panel 32 by removing the bolt 80.

[0006] According to conventional installation method 2, as shown in FIG. 7(B), the partition panel 31 is fixed at its upper end on the vehicle exterior side in the vehicle width direction by a bolt 90 via a spacer 91 to a ceiling frame 40 supported by the roof structure. A connecting member 92 with an L-shaped cross section is fastened at one straight portion between the partition panel 31 and the head of the bolt 90. The other straight portion of the connecting member 92 bends from the lower end of the one straight portion toward the vehicle interior side in the vehicle width direction. Meanwhile, the ceiling panel 32 is fastened at its outer end in the vehicle width direction to one of the parallel straight portions of a receiving member 94 with a Z-shaped cross section by a screw 93. The other parallel straight portion of the receiving member 94 is fastened to the other straight portion of the connecting member 92 by a bolt 96 via a liner plate 95. As a result, the ceiling panel 32 is positioned lower than the upper end of the partition panel 31 and is installed a predetermined distance toward the vehicle interior side in the vehicle width direction from the partition panel 31. That is, a gap S9 is formed between the interior end of the partition panel 31 and the ceiling panel 32 in the vehicle width direction. However, the bolt 90 is blocked from the gap S9 by the connecting member 92 and the receiving member 94. Therefore, if it is desired to remove the partition panel 31, it is necessary to first remove the ceiling panel 32 by removing the bolt 96 from the gap S9, and then remove the partition panel 31 by removing the bolt 90.

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-338649 Summary of the Invention [Problem to be solved by the invention]

[0008] As described above, according to conventional installation method 1, when it is desired to remove ceiling panel 32, it is necessary to first remove partition panel 31. On the other hand, according to conventional installation method 2, when it is desired to remove partition panel 31, it is necessary to first remove ceiling panel 32.

[0009] The present invention has been made to solve such problems, and has an object to provide a railway vehicle in which both the partition panel and the ceiling panel can be easily removed. [Means for solving the problem]

[0010] In order to achieve the above object, a railway vehicle according to one aspect of the present invention has the following features.

[0011] (1) A railway vehicle comprising a partition panel that divides an aisle of an access platform, a ceiling panel, and a ceiling frame supported on a roof structure, an end of the partition panel and an end of the ceiling panel are disposed at upper corners of the passage; The ceiling ribs have a flat vertical piece parallel to the vehicle body height direction, and a flat horizontal piece bent at a substantially right angle from an upper end of the vertical piece, the vertical piece is disposed on the rear side of the partition panel relative to the passage; the horizontal piece is disposed on the rear side of the ceiling panel relative to the passageway, The partition panel is detachably fixed to the vertical piece by a partition panel fastener, either directly or via a partition joining member joined to the partition panel; The ceiling panel is characterized in that it is detachably fixed to the horizontal piece by a ceiling panel fastener, either directly or via a ceiling joining member joined to the ceiling panel. According to the aspect described in (1) above, the partition panel is detachably fixed to the vertical piece by the partition panel fastener, either directly or via a partition joint member joined to the partition panel, and the ceiling panel is detachably fixed to the horizontal piece by the ceiling panel fastener, either directly or via a ceiling joint member joined to the ceiling panel. Therefore, the ceiling panel can be removed without removing the partition panel, and the partition panel can be removed without removing the ceiling panel. In other words, removal of both the partition panel and the ceiling panel is easy.

[0012] (2) In the railway vehicle described in (1), a gap may be formed between the end of the partition panel and the end of the ceiling panel at an upper corner of the aisle, and a shielding member may be disposed in the gap to shield the side of the gap opposite the aisle. The aspect described in (2) above can prevent the side opposite the aisle from being exposed through the gap at the upper corner of the aisle. Therefore, it is possible to prevent a decrease in the aesthetic appearance of the inside of the platform. [Effects of the Invention]

[0013] According to the present invention, both the partition panel and the ceiling panel can be easily removed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0015] First Embodiment Next, a railway vehicle according to a first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic plan view of a railway vehicle 1 according to a first embodiment of the present invention (hereinafter referred to as "vehicle 1"), as seen from the interior side of the vehicle. For convenience, in FIG. 1, it is assumed that vehicle 1 travels to the right. In the following description, the right side of vehicle 1 travelling is referred to as the "front side," and the left side opposite the travelling side is referred to as the "rear side." In the following description, the right and left sides of vehicle 1A constituting vehicle 1, looking from the rear side to the front side in the longitudinal direction (car body longitudinal direction) of vehicle body 1A in the width direction (car body width direction), will be referred to as the "right side" and the "left side," respectively. Furthermore, the "outside side" and "inside side" in the car body width direction will be referred to as the "outside side in the width direction" and the "inside side in the width direction." In the following description, the upper and lower sides of vehicle body 1A in the height direction (car body height direction) will be simply referred to as the "upper side" and the "lower side," respectively.

[0016] The vehicle 1 will now be described. The vehicle 1 is a first-class vehicle. The body structure 10 that constitutes the car body 1A of the vehicle 1 comprises an underframe (not shown), a pair of left and right side bodies 11, a pair of front and rear end bodies 12, and a roof body structure (not shown). The body structure 10 has a symmetrical structure in the car body width direction. However, the structure of the body structure 10 can be set appropriately and does not have to be symmetrical in the car body width direction.

[0017] The vehicle 1 has a passenger compartment R1, a rear platform R2, and a front platform R3. From the front, the front platform R3, passenger compartment R1, and rear platform R2 are arranged. The front platform R3 and passenger compartment R1 are separated by a front partition wall 20. The passenger compartment R1 and rear platform R2 are separated by a rear partition wall 21. The front partition wall 20 and the rear partition wall 21 are parallel to the width direction of the vehicle body in a plan view. Note that the vehicle 1 may be composed of a passenger compartment R1 and a rear platform R2, or may be composed of a passenger compartment R1 and a front platform R3.

[0018] The front platform R3 has a passage 37 that is generally T-shaped in plan view. The passage 37 has a first passage 37A that is parallel to the longitudinal direction of the vehicle body and a second passage 37B that is parallel to the width direction of the vehicle body. The first passage 37A is formed in the center of the front platform R3 in the width direction of the vehicle body. The second passage 37B is formed at the rear end of the front platform R3 in the longitudinal direction of the vehicle body.

[0019] The passage 37 is divided by partition panels 38 that are erected vertically on the floor surface F3. The partition panels 38 include a first partition panel 38A and a second partition panel 38B. The first partition panel 38A is disposed in front of and to the left of the intersection of the first passage 37A and the second passage 37B. The second partition panel 38B is disposed in front of and to the right of the intersection of the first passage 37A and the second passage 37B.

[0020] The first partition panel 38A and the second partition panel 38B each have a straight portion (first straight portion) that faces the first passage 37A in the vehicle body width direction, in other words, that defines the first passage 37A, a straight portion (second straight portion) that faces the second passage 37B in the vehicle body longitudinal direction, in other words, that defines the second passage 37B, and a corner portion that connects the first straight portion and the second straight portion in an arc shape.

[0021] The rear platform R2 has a passage 30 that is generally cross-shaped in plan view. The passage 30 includes a first passage 30A that is parallel to the longitudinal direction of the vehicle body and a second passage 30B that is parallel to the width direction of the vehicle body. The first passage 30A is formed in the center of the rear platform R2 in the width direction of the vehicle body. The second passage 30B is formed rearward of the center of the rear platform R2 in the longitudinal direction of the vehicle body. The shape of the passage 30 formed in the rear platform R2 is not limited to a generally cross shape in plan view and may be modified as appropriate. For example, the shape of the passage 30 may be a generally T-shape or a generally L-shape in plan view. Furthermore, the shape of the passage 30 may be, for example, linear, curved, or wavy in plan view. When the shape of the passage 30 is generally straight in plan view, the passage 30 may be formed on one side of the rear platform R2 in the width direction of the vehicle body, or may be formed in the center of the rear platform R2 in the width direction of the vehicle body.

[0022] The aisle 30 is divided by partition panels 31 that are erected perpendicularly to the floor surface F2. The partition panels 31 include a front-left partition panel 31A, a front-right partition panel 31B, a rear-left partition panel 31C, and a rear-right partition panel 31D. The front-left partition panel 31A is located in front of and to the left of the intersection of the first aisle 30A and the second aisle 30B. The front-right partition panel 31B is located in front of and to the right of the intersection of the first aisle 30A and the second aisle 30B. The rear-left partition panel 31C is located behind and to the left of the intersection of the first aisle 30A and the second aisle 30B. The rear-right partition panel 31D is located behind and to the right of the intersection of the first aisle 30A and the second aisle 30B.

[0023] The front left-hand partition panel 31A, the front right-hand partition panel 31B, the rear left-hand partition panel 31C, and the rear right-hand partition panel 31D each have a straight portion (first straight portion) that faces the first passage 30A in the vehicle body width direction, in other words, that defines the first passage 30A, a straight portion (second straight portion) that faces the second passage 30B in the vehicle body longitudinal direction, in other words, that defines the second passage 30B, and a corner portion that connects the first straight portion and the second straight portion at approximately right angles and in an arc shape.

[0024] On the opposite side of the partition panel 31 from the aisle 30, a space in which equipment and the like can be installed is formed. The space on the opposite side of the aisle 30 via this partition panel 31 is referred to as the "equipment space 33." Within the equipment space 33, the space on the opposite side of the aisle 30 from the front left-hand partition panel 31A is referred to as the "front left-hand equipment space 33A," the space on the opposite side of the aisle 30 from the front right-hand partition panel 31B is referred to as the "front right-hand equipment space 33B," the space on the opposite side of the aisle 30 from the rear left-hand partition panel 31C is referred to as the "rear left-hand equipment space 33C," and the space on the opposite side of the aisle 30 from the rear right-hand partition panel 31D is referred to as the "rear right-hand equipment space 33D."

[0025] A multipurpose room R24 is installed in the front left equipment space 33A. A washbasin R21, a toilet R22, and a machine room R23 are installed in this order from the front side in the front right equipment space 33B.

[0026] For convenience, in the entire interior space of the rear entrance platform R2, the side on which the aisle 30 is formed with respect to the direction perpendicular to the extension direction (partition panel extension direction) of each of the partition panels 31A to 31D in a plan view will be referred to as the "inner aisle side," and the side on which the equipment space 33 is formed will be referred to as the "outer aisle side." Furthermore, for the first linear portions of each of the partition panels 31A to 31D, the vehicle body longitudinal direction is the partition panel extension direction, and the vehicle body width direction is the direction perpendicular to the partition panel extension direction. Meanwhile, for the second linear portions of each of the partition panels 31A to 31D, the vehicle body width direction is the partition panel extension direction, and the vehicle body longitudinal direction is the direction perpendicular to the partition panel extension direction.

[0027] Next, the rear platform R2 will be described in detail. Figure 2 is an explanatory diagram mainly for explaining the allocation of ceiling panels 32 in the rear platform R2. Ceiling panels 32 are installed on the rear platform R2. The ceiling panels 32 define the upper side of the interior space of the rear platform R2. The ceiling panels 32 include an aisle ceiling panel 32A facing the aisle 30 and an equipment ceiling panel 32B facing the equipment space 33 in the vehicle body height direction.

[0028] The equipment ceiling panels 32B include a first equipment ceiling panel 32B1 facing the front left equipment space 33A, a second equipment ceiling panel 32B2 facing the front right equipment space 33B, a third equipment ceiling panel 32B3 facing the rear left equipment space 33C, and a fourth equipment ceiling panel 32B4 facing the rear right equipment space 33D.

[0029] The passage ceiling panel 32A is formed in a cross shape in plan view that is generally the same as the passage 30. However, the passage ceiling panel 32A is slightly smaller than the passage 30 in plan view overall.

[0030] In addition, the aisle ceiling panel 32A is integrally formed by a plurality of parts, specifically, a first aisle ceiling panel 32A1, a second aisle ceiling panel 32A2, a third aisle ceiling panel 32A3, a fourth aisle ceiling panel 32A4, a fifth aisle ceiling panel 32A5, a sixth aisle ceiling panel 32A6, and a seventh aisle ceiling panel 32A7.

[0031] The first aisle ceiling panel 32A1, the second aisle ceiling panel 32A2, and the third aisle ceiling panel 32A3 are disposed between the front left partition panel 31A and the front right partition panel 31B in a plan view and face the first aisle 30A in the vehicle body height direction. The first aisle ceiling panel 32A1, the second aisle ceiling panel 32A2, and the third aisle ceiling panel 32A3 are arranged side by side without any gaps in the front-to-rear direction. Relatively, the first aisle ceiling panel 32A1 is disposed at the forefront, and the third aisle ceiling panel 32A3 is disposed at the rear. The second aisle ceiling panel 32A2 is connected to both the first aisle ceiling panel 32A1 disposed at the front and the third aisle ceiling panel 32A3 disposed at the rear.

[0032] The fourth aisle ceiling panel 32A4 is disposed between the rear left partition panel 31C and the rear right partition panel 31D in a plan view and faces the first aisle 30A in the vehicle height direction. The fifth aisle ceiling panel 32A5 is disposed between the front left partition panel 31A and the rear left partition panel 31C in a plan view and faces the second aisle 30B in the vehicle height direction. The sixth aisle ceiling panel 32A6 is disposed between the front right partition panel 31B and the rear right partition panel 31D in a plan view and faces the second aisle 30B in the vehicle height direction.

[0033] The seventh aisle ceiling panel 32A7 is connected to the third aisle ceiling panel 32A3 located at the front, the fourth aisle ceiling panel 32A4 located at the rear, the fifth aisle ceiling panel 32A5 located on the left, and the sixth aisle ceiling panel 32A6 located on the right, and faces the first aisle 30A and the second aisle 30B in the vehicle height direction.

[0034] In addition, except for the connection portions of the seventh aisle ceiling panel 32A7 with the third aisle ceiling panel 32A3, the fourth aisle ceiling panel 32A4, the fifth aisle ceiling panel 32A5, and the sixth aisle ceiling panel 32A6, the seventh aisle ceiling panel 32A7 faces the corner portions of the front left partition panel 31A, the front right partition panel 31B, the rear left partition panel 31C, and the rear right partition panel 31D in a plan view.

[0035] The first passage ceiling panel 32A1, the second passage ceiling panel 32A2, the third passage ceiling panel 32A3, the fourth passage ceiling panel 32A4, the fifth passage ceiling panel 32A5, and the sixth passage ceiling panel 32A6 are formed in a rectangular shape in a plan view. Furthermore, the connection portions of the seventh passage ceiling panel 32A7 with the third passage ceiling panel 32A3, the fourth passage ceiling panel 32A4, the fifth passage ceiling panel 32A5, and the sixth passage ceiling panel 32A6 are formed in a linear shape. On the other hand, except for the connection portions of the seventh aisle ceiling panel 32A7 with the third aisle ceiling panel 32A3, the fourth aisle ceiling panel 32A4, the fifth aisle ceiling panel 32A5, and the sixth aisle ceiling panel 32A6, the seventh aisle ceiling panel 32A7 is formed in an arc shape with a radius of curvature larger than the radius of curvature of the corner portions of the front left partition panel 31A, the front right partition panel 31B, the rear left partition panel 31C, and the rear right partition panel 31D.

[0036] The vehicle width direction lengths of the first aisle ceiling panel 32A1, the second aisle ceiling panel 32A2, the third aisle ceiling panel 32A3, and the fourth aisle ceiling panel 32A4 are shorter than the vehicle width direction length of the first aisle 30A. The first aisle ceiling panel 32A1, the second aisle ceiling panel 32A2, the third aisle ceiling panel 32A3, and the fourth aisle ceiling panel 32A4 are evenly spaced relative to the first aisle 30A in the vehicle width direction in a plan view. The vehicle length directions of the fifth aisle ceiling panel 32A5 and the sixth aisle ceiling panel 32A6 are shorter than the vehicle length direction length of the second aisle 30B. The fifth aisle ceiling panel 32A5 and the sixth aisle ceiling panel 32A6 are evenly spaced relative to the second aisle 30B in the vehicle length direction in a plan view. Therefore, the partition panel 31 and the aisle ceiling panel 32A face each other at a small distance in a direction perpendicular to the extending direction of the partition panel in a plan view. In other words, in a plan view, the outer edge of the aisle ceiling panel 32A is located closer to the aisle than the partition panel 31.

[0037] 3(A) is a schematic diagram of the front-left partition panel 31A as viewed from approximately the center in the vehicle width direction of the first passage 30A, and FIG. 3(B) is a schematic diagram of the front-left partition panel 31A as viewed from approximately the center in the vehicle length direction of the second passage 30B. The front-left partition panel 31A is integrally formed of five parts along the extension direction in a plan view, specifically, a first front-left partition panel 31A1, a second front-left partition panel 31A2, a third front-left partition panel 31A3, a fourth front-left partition panel 31A4, and a fifth front-left partition panel 31A5, which are arranged in order from the front side and connected to each other so as to correspond to the layout of the ceiling panel 32.

[0038] In a plan view, the first front-left partition panel 31A1, the second front-left partition panel 31A2, the third front-left partition panel 31A3, the fourth front-left partition panel 31A4, and the fifth front-left partition panel 31A5 face the first aisle ceiling panel 32A1, the second aisle ceiling panel 32A2, the third aisle ceiling panel 32A3, the seventh aisle ceiling panel 32A7, and the fifth aisle ceiling panel 32A5, respectively, in a direction perpendicular to the respective extension directions. The first front-left partition panel 31A1, the second front-left partition panel 31A2, and the third front-left partition panel 31A3 form the first linear portion and are generally flat. The fifth front-left partition panel 31A5 forms the second linear portion and is generally flat. The fourth front-left partition panel 31A4 forms the corner portion and is generally quarter-cylindrical.

[0039] The first front-left partition panel 31A1, the second front-left partition panel 31A2, the third front-left partition panel 31A3, the fourth front-left partition panel 31A4, and the fifth front-left partition panel 31A5 have the same length (height) in the vehicle body height direction. The first front-left partition panel 31A1, the second front-left partition panel 31A2, the third front-left partition panel 31A3, the fourth front-left partition panel 31A4, and the fifth front-left partition panel 31A5 are formed lower than the aisle ceiling panel 32A. In other words, the upper end of the front-left partition panel 31A is located lower than the aisle ceiling panel 32A.

[0040] The vehicle body height direction length (height) of the front right-side partition panel 31B, the rear left-side partition panel 31C, and the rear right-side partition panel 31D is the same as the vehicle body height direction length (height) of the front left-side partition panel 31A. Therefore, the front right-side partition panel 31B, the rear left-side partition panel 31C, and the rear right-side partition panel 31D are also formed lower than the aisle ceiling panel 32A. In other words, the upper ends of the front right-side partition panel 31B, the rear left-side partition panel 31C, and the rear right-side partition panel 31D are positioned lower than the aisle ceiling panel 32A.

[0041] As described above, in a plan view, the outer edge of the aisle ceiling panel 32A is located closer to the inside of the aisle than the partition panel 31. Furthermore, the upper end of the partition panel 31 is located lower than the aisle ceiling panel 32A. Therefore, in a cross section of the aisle 30 perpendicular to the extending direction of the partition panels, a gap is formed between the upper end of the partition panel 31 and the outer edge of the aisle ceiling panel 32A. This gap is included in the upper corner of the aisle 30. Hereinafter, this gap will be referred to as a "corner gap 30CG."

[0042] Of the corner gaps 30CG, the one relating to the front left-hand partition panel 31A is referred to as the "front left-hand corner gap 30CG1," the one relating to the front right-hand partition panel 31B is referred to as the "front right-hand corner gap 30CG2," the one relating to the rear left-hand partition panel 31C is referred to as the "rear left-hand corner gap 30CG3," and the one relating to the rear right-hand partition panel 31D is referred to as the "rear right-hand corner gap 30CG4." Furthermore, among the front left corner gaps 30CG1, those relating to the front left first partition panel 31A1, the front left second partition panel 31A2, the front left third partition panel 31A3, the front left fourth partition panel 31A4, and the front left fifth partition panel 31A5 are referred to as the "front left first corner gap 30CG11," "front left second corner gap 30CG12," "front left third corner gap 30CG13," "front left fourth corner gap 30CG14," and "front left fifth corner gap 30CG15," respectively.

[0043] In addition, like the front left-hand partition panel 31A, the front right-hand partition panel 31B, the rear left-hand partition panel 31C, and the rear right-hand partition panel 31D are integrally constructed with multiple parts arranged side by side without any gaps along the extension direction in a plan view, corresponding to the layout of the ceiling panel 32.

[0044] The upper corners of the aisle 30 formed by the front-left partition panel 31A, the front-right partition panel 31B, the rear-left partition panel 31C, and the rear-right partition panel 31D and the ceiling panel 32 are referred to as the "front-left corner 30C1," "front-right corner 30C2," "rear-left corner 30C3," and "rear-right corner 30C4," respectively. Furthermore, within the front-left corner 30C1, the parts relating to the first front-left partition panel 31A1, the second front-left partition panel 31A2, the third front-left partition panel 31A3, the fourth front-left partition panel 31A4, and the fifth front-left partition panel 31A5 are referred to as the "first front-left corner 30C11," "second front-left corner 30C12," "third front-left corner 30C13," "fourth front-left corner 30C14," and "fifth front-left corner 30C15," respectively.

[0045] FIG. 4 is a partial cross-sectional schematic diagram that simply shows the fixing structure of the front left first partition panel 31A1 and the first aisle ceiling panel 32A1 in the XX cross section of FIGS. 2 and 3, as well as a structure (shielding structure) that shields the side of the front left first corner gap 30CG11 opposite the first aisle 30A (preventing the outside of the first aisle 30A from being seen through the front left first corner gap 30CG11). In FIG. 4, the left-right direction is the vehicle body width direction, and the up-down direction is the vehicle body height direction. The vehicle body width direction is also the "direction perpendicular to the extending direction of the partition panel."

[0046] 4, a partition unit SU including the front-left first partition panel 31A1 and a ceiling unit TU1 including the first passage ceiling panel 32A1 are each independently detachably fixed to the ceiling frame 41. A shielding member 71 is disposed in the front-left first corner gap 30CG11 formed in the front-left first corner 30C11, and the shielding member 71 shields the front-left first corner gap 30CG11 on the side opposite to the first passage 30A.

[0047] The ceiling ribs 41 have a plate-like vertical piece 41a that extends vertically with a constant width (a constant length in the longitudinal direction of the car body) and a plate-like horizontal piece 41b that is bent at a substantially right angle from the upper end of the vertical piece 41a toward the inside of the car in the width direction (to the left in FIG. 4). Note that multiple ceiling ribs 41 are installed at predetermined intervals along the extension direction of the front left first partition panel 31A1 (the longitudinal direction of the car body). Furthermore, the ceiling ribs 41 are supported by rafters (not shown) that form the roof structure.

[0048] The partition unit SU has a front-left first partition panel 31A1 and a partition joint member 51. The partition joint member 51 extends over the entire length of the front-left first partition panel 31A1 in the vehicle body longitudinal direction. A cross section of the partition joint member 51 perpendicular to the vehicle body longitudinal direction (a cross section perpendicular to the longitudinal direction) is generally L-shaped. In this cross section, the partition joint member 51 has a plate-shaped partition vertical piece 51a parallel to the vehicle body height direction and a plate-shaped partition horizontal piece 51b parallel to the vehicle body width direction. The partition horizontal piece 51b is bent at a substantially right angle from the lower end of the partition vertical piece 51a toward the vehicle outer side in the width direction (to the right in FIG. 4).

[0049] The upper end of the first front-left partition panel 31A1 is adhered to the surface of the partition vertical piece 51a on the vehicle interior side in the width direction. In this adhered state, approximately half of the upper side of the partition vertical piece 51a protrudes above the upper end of the first front-left partition panel 31A1.

[0050] The partition unit SU is fixed to the ceiling frame 41 by a partition joint member 51. More specifically, the portion of the partition vertical piece 51a of the partition unit SU that protrudes above the front left first partition panel 31A1 is fixed to the interior surface of the vertical piece 41a of the ceiling frame 41 in the width direction via a spacer 52. This fixation is achieved by fastening with a bolt 53 inserted into the partition vertical piece 51a and vertical piece 41a from the first passage 30A side, and a floating nut 54 arranged on the side of the vertical piece 41a opposite the first passage 30A. In other words, the partition unit SU is detachably fixed to the ceiling frame 41.

[0051] The partition vertical piece 51a and the vertical piece 41a are fixed to each other at the upper end of the partition vertical piece 51a and the lower end of the vertical piece 41a. Therefore, the upper end of the partition vertical piece 51a is located higher than the lower end of the vertical piece 41a. In addition, the upper end of the front-left first partition panel 31A1 and the lower end of the vertical piece 41a are located at approximately the same position in the vehicle body height direction.

[0052] The ceiling unit TU1 has a first passage ceiling panel 32A1. The first passage ceiling panel 32A1 is directly fixed to the ceiling frame 41. More specifically, the first passage ceiling panel 32A1 is fixed to the lower surface of the horizontal piece 41b of the ceiling frame 41 via a spacer 62. This fixing is performed by fastening the first passage ceiling panel 32A1 and the horizontal piece 41b from the first passage 30A side with bolts 63 inserted into the horizontal piece 41b, and with floating nuts 64 arranged on the side of the horizontal piece 41b opposite the first passage 30A. In other words, the ceiling unit TU1 is detachably fixed to the ceiling frame 41.

[0053] The first aisle ceiling panel 32A1 and the horizontal piece 41b are fixed at the outer width end of the first aisle ceiling panel 32A1 and the inner width end of the horizontal piece 41b. Therefore, the outer edge of the first aisle ceiling panel 32A1 is located further outboard in the width direction than the inner width end of the horizontal piece 41b.

[0054] The shielding member 71 is installed in the first front-left corner gap 30CG11. The side of the first front-left corner gap 30CG11 opposite the first passage 30A is shielded by the shielding member 71. In other words, the shielding member 71 prevents the side of the first front-left corner gap 30CG11 opposite the first passage 30A from being exposed.

[0055] The shielding member 71 extends over the entire length of the first aisle ceiling panel 32A1 in the longitudinal direction of the car body. The shielding member 71 is formed by bending a single metal plate at a right angle. That is, the cross section of the shielding member 71 perpendicular to the longitudinal direction of the car body is generally L-shaped. In this cross section, the shielding member 71 has a plate-shaped shielding vertical portion 71a parallel to the height direction of the car body, a plate-shaped shielding horizontal portion 71b parallel to the width direction of the car body, and a shielding bent portion 71c bent in an arc shape to smoothly connect the orthogonally arranged shielding vertical portion 71a and shielding horizontal portion 71b.

[0056] The shielding member 71 is fixed to the partition unit SU. Specifically, the shielding vertical portion 71a of the shielding member 71 is directly fixed to a portion of the partition vertical piece 51a that protrudes above the upper end of the first front-left partition panel 31A1 in the vehicle body height direction. This fixation is achieved by fastening using screws 74 inserted into the shielding vertical portion 71a and the partition vertical piece 51a from the first passage 30A side, and a floating nut (not shown) located on the side of the partition vertical piece 51a opposite the first passage 30A. In other words, the shielding member 71 is detachably fixed to the ceiling frame 41 via the partition unit SU. The lower end of the shielding vertical portion 71a is located immediately above the upper end of the first front-left partition panel 31A1.

[0057] The screw 74 is disposed at approximately the center of the shielding vertical portion 71a in the vehicle body height direction. The head of the screw 74 is exposed in the first passage 30A. That is, the screw 74 faces the first passage 30A in the vehicle body width direction via the first front left corner gap 30CG11. Although not shown, the position of the screw 74 does not overlap the position of the bolt 53 in the vehicle body longitudinal direction, and the bolt 53 is covered by the shielding vertical portion 71a. That is, the location where the partition unit SU and the ceiling frame 41 are fixed by the bolt 53 is shielded from the first passage 30A side by the shielding vertical portion 71a.

[0058] When the shielding member 71 is fixed to the partition unit SU, the inner end of the shielding horizontal portion 71b in the width direction is located closer to the inner side of the vehicle in the width direction than the bolt 63. In addition, the upper surface of the shielding horizontal portion 71b abuts against the outer side end of the first aisle ceiling panel 32A1 in the width direction. Therefore, the shielding member 71 essentially shields the side of the front left first corner gap 30CG11 opposite to the first aisle 30A, and also closes the front left first corner gap 30CG11. Note that the shielding horizontal portion 71b itself is not fixed to the ceiling unit TU1.

[0059] Additionally, the fixing points between the ceiling unit TU1 and the ceiling ribs 41 by the bolts 63 are covered from the first passage 30A side by the shielding horizontal portions 71b. Therefore, the fixing points between the ceiling unit TU1 and the ceiling ribs 41 by the bolts 63 are shielded by the shielding members 71.

[0060] Incidentally, when the shielding member 71 is installed, the bolts 53 for attaching and detaching the partition unit SU to and from the ceiling frame 41 are shielded from the first passage 30A side by the shielding vertical portion 71a of the shielding member 71. Therefore, in this state, it is impossible to come into contact with the bolts 53. On the other hand, when the shielding member 71 is installed, the bolts 63 for attaching and detaching the ceiling unit TU1 to and from the ceiling frame 41 are shielded from the first passage 30A by the shielding horizontal portion 71b of the shielding member 71. Therefore, in this state, it is impossible to come into contact with the bolts 63.

[0061] However, when the shielding member 71 is installed, the screws 74 for attaching and detaching the shielding member 71 face the first passage 30A via the first front-left corner gap 30CG11 in the vehicle body width direction. Therefore, the screws 74 can be easily accessed through the first front-left corner gap 30CG11. In other words, the shielding member 71 can be easily removed from the partition unit SU.

[0062] With the shielding member 71 removed from the partition unit SU, the bolt 53 faces the first passage 30A via the first front-left corner gap 30CG11 in the vehicle body width direction, and the bolt 63 faces the first passage 30A via the first front-left corner gap 30CG11 in the vehicle body height direction. Therefore, the bolt 53 and the bolt 63 can be easily accessed through the first front-left corner gap 30CG11. In other words, the partition unit SU and the ceiling unit TU1 can be easily removed from the ceiling frame 41.

[0063] Furthermore, even after removing the partition unit SU or the ceiling unit TU1, in a state where the shielding member 71 is not installed, the partition unit SU or the ceiling unit TU1 can be easily fixed to the ceiling frame 41 with the bolts 53 or the bolts 63. Furthermore, by subsequently fixing the shielding member 71 to the partition unit SU with the screws 74, the original installation state can be restored.

[0064] In addition, the distance in the vehicle width direction between the outer edge (the outer width end of the first aisle ceiling panel 32A1) and the inner width surface of the front left first partition panel 31A1 in the first embodiment is shorter than the distance in the vehicle width direction between the outer edge (the outer width end of the first aisle ceiling panel 32A1) and the inner width surface of the front left first partition panel 31A1 in the third embodiment described below.

[0065] As described above, the vehicle 1 according to the first embodiment includes the front left first partition panel 31A1 and the first passage ceiling panel 32A1 that partition the first passage 30A of the rear platform R2, and the ceiling frame 41 supported by the roof structure, and an end of the front left first partition panel 31A1 and an end of the first passage ceiling panel 32A1 are arranged at the front left first corner 30C11 of the first passage 30A, and the ceiling frame 41 has a flat vertical piece 41a that is parallel to the vehicle body height direction and a flat horizontal piece 41b that is bent at a substantially right angle from the upper end of the vertical piece 41a, and the vertical piece 41a is The vertical piece 41a is arranged on the back side of the front-left first partition panel 31A1, which is connected to the first passage 30A, and the horizontal piece 41b is arranged on the back side of the first passage ceiling panel 32A1, which is connected to the first passage 30A. The front-left first partition panel 31A1 is removably fixed to the vertical piece 41a by a bolt 53 and a floating nut 54 (partition panel fixing device) via a partition joining member 51 joined to the front-left first partition panel 31A1, and the first passage ceiling panel 32A1 is directly removably fixed to the horizontal piece 41b by a bolt 63 and a floating nut 64 (ceiling panel fixing device). The front-left first partition panel 31A1 is detachably fixed to the vertical piece 41a via a partition joint member 51 with a bolt 53 and a floating nut 54 (partition panel fastener), and the first aisle ceiling panel 32A1 is detachably fixed directly to the horizontal piece 41b with a bolt 63 and a floating nut 64 (ceiling panel fastener). Therefore, the first aisle ceiling panel 32A1 can be removed without removing the front-left first partition panel 31A1, and the front-left first partition panel 31A1 can be removed without removing the first aisle ceiling panel 32A1. In other words, both the front-left first partition panel 31A1 and the first aisle ceiling panel 32A1 can be easily removed.

[0066] Furthermore, in the vehicle 1 according to the first embodiment, a front-left first corner gap 30CG11 is formed between an end of the front-left first partition panel 31A1 and an end of the first passage ceiling panel 32A1 at the front-left first corner 30C11 of the first passage 30A, and a shielding member 71 is disposed in the front-left first corner gap 30CG11 to shield the side of the front-left first corner gap 30CG11 opposite the first passage 30A. This prevents the side of the first passage 30A opposite the first passage 30A from being exposed through the front-left first corner gap 30CG11 of the front-left first corner 30C11 of the first passage 30A. This prevents a deterioration in the aesthetic appearance of the interior of the rear platform R2.

[0067] Furthermore, in the vehicle 1 according to the first embodiment, the shielding member 71 is formed by bending a single metal plate. Therefore, it is possible to suppress an increase in the cost of the vehicle 1. Furthermore, in the vehicle 1 according to the first embodiment, the distance in the vehicle body width direction between the outer edge (the outer-side end of the width direction) of the first aisle ceiling panel 32A1 and the inner-side surface of the width direction of the front-left first partition panel 31A1 is formed to be shorter than the distance in the vehicle body width direction between the outer edge (the outer-side end of the width direction) of the first aisle ceiling panel 32A1 and the inner-side surface of the width direction of the front-left first partition panel 31A1 in the third embodiment described below. Therefore, it is possible to prevent a decrease in the aesthetic appearance of the interior of the rear access platform R2.

[0068] Second Embodiment Next, a vehicle 1 according to a second embodiment of the present invention will be described. In the following, the second embodiment will be mainly described with respect to differences from the first embodiment. Furthermore, the same reference numerals and terms will be used for the same or similar corresponding configurations as those in the first embodiment.

[0069] 5 is a simplified partial cross-sectional schematic diagram showing the fastening structure of the front-left first partition panel 31A1 and the first aisle ceiling panel 32A1 according to the second embodiment, and the shielding structure of the front-left first corner gap 30CG11, taken along the line XX in FIGS. 2 and 3. In FIG. 5, the left-right direction corresponds to the vehicle body width direction, and the up-down direction corresponds to the vehicle body height direction. The vehicle body width direction is also the "direction perpendicular to the partition panel extension direction."

[0070] 5, a partition unit SU including the front-left first partition panel 31A1 and a ceiling unit TU1 including the first passage ceiling panel 32A1 are each independently detachably fixed to the ceiling frame 42. A shielding member 72 is disposed in the front-left first corner gap 30CG11 formed in the front-left first corner 30C11, and the shielding member 72 shields the front-left first corner gap 30CG11 on the side opposite to the first passage 30A.

[0071] The ceiling rib 42, like the ceiling rib 41 of the first embodiment, has a plate-shaped vertical piece 42a extending vertically with a constant width (a constant length in the longitudinal direction of the vehicle body), and a plate-shaped horizontal piece 42b bent at approximately a right angle from the upper end of the vertical piece 42a toward the inside of the vehicle in the width direction (to the left in Figure 5).

[0072] The structure of the partition unit SU and the structure of the ceiling unit TU1 are the same as those in the first embodiment. Furthermore, the fixing structure between the partition unit SU and the ceiling ribs 42 is the same as the fixing structure between the partition unit SU and the ceiling ribs 41 in the first embodiment. Furthermore, the fixing structure between the ceiling unit TU1 and the ceiling ribs 42 is the same as the fixing structure between the ceiling unit TU1 and the ceiling ribs 41 in the first embodiment. Therefore, the partition unit SU and the ceiling unit TU1 are detachably fixed to the ceiling ribs 42.

[0073] The shielding member 72 is installed in the first front-left corner gap 30CG11. The side of the first front-left corner gap 30CG11 opposite the first passage 30A is shielded by the shielding member 72. In other words, the shielding member 72 prevents the side of the first front-left corner gap 30CG11 opposite the first passage 30A from being exposed.

[0074] The shielding member 72 extends over the entire length of the first aisle ceiling panel 32A1 in the longitudinal direction of the car body. A cross section of the shielding member 72 perpendicular to the longitudinal direction of the car body is generally E-shaped. In this cross section, the shielding member 72 has a plate-shaped shielding vertical piece 72a parallel to the height direction of the car body, and plate-shaped shielding upper horizontal piece 72b1, shielding central horizontal piece 72b2, and shielding lower horizontal piece 72b3 parallel to the width direction of the car body.

[0075] The upper shielding horizontal piece 72b1 is formed at a substantially right angle from the upper end of the shielding vertical piece 72a in the car body height direction toward the vehicle interior in the width direction. The central shielding horizontal piece 72b2 is formed at a substantially right angle from the center of the shielding vertical piece 72a in the car body height direction toward the vehicle interior in the width direction. The lower shielding horizontal piece 72b3 is formed at a substantially right angle from the lower end of the shielding vertical piece 72a in the car body height direction toward the vehicle interior in the width direction.

[0076] In terms of length in the vehicle width direction, the upper shielding horizontal piece 72b1 is longer than the central shielding horizontal piece 72b2 and the lower shielding horizontal piece 72b3. In the vehicle width direction, the distance between the inner-side tip of the upper shielding horizontal piece 72b1 and the inner-side tip of the central shielding horizontal piece 72b2 is approximately the same as the distance between the inner-side tip of the central shielding horizontal piece 72b2 and the inner-side tip of the lower shielding horizontal piece 72b3.

[0077] In addition, in the vehicle body height direction, the distance between the upper shielding horizontal piece 72b1 and the central shielding horizontal piece 72b2 is substantially the same as the distance between the central shielding horizontal piece 72b2 and the lower shielding horizontal piece 72b3.

[0078] The shielding member 72 is fixed to the partition unit SU. More specifically, the shielding vertical piece 72a of the shielding member 72 is fixed via a liner plate 75 to the vehicle-interior-side surface in the width direction of the portion of the partition vertical piece 51a of the partition joint member 51 that protrudes above the front-left first partition panel 31A1. This fixation is achieved by fastening using screws 77 inserted into the shielding vertical piece 72a and the partition vertical piece 51a from the first passage 30A side, and a floating nut (not shown) arranged on the side of the partition vertical piece 51a opposite the first passage 30A. In other words, the shielding member 72 is detachably fixed to the ceiling frame 42 via the partition unit SU.

[0079] The screw 77 is disposed in a portion between the shielding center horizontal piece 72b2 and the shielding lower horizontal piece 72b3 of the shielding vertical piece 72a. The head of the screw 77 is exposed in the first passage 30A. That is, the screw 77 faces the first passage 30A in the vehicle body width direction across the first front left corner gap 30CG11. Although not shown, the position of the screw 77 does not overlap the position of the bolt 53 in the vehicle body longitudinal direction, and the bolt 53 is covered by the shielding vertical piece 72a. That is, the portion where the partition unit SU and the ceiling frame 42 are fixed by the bolt 53 is shielded from the first passage 30A side by the shielding vertical piece 72a.

[0080] When the shielding member 72 is fixed to the partition unit SU, the widthwise inboard end of the upper horizontal shielding piece 72b1 is located on the inboard side of the bolt 63, the widthwise inboard end of the central horizontal shielding piece 72b2 is located at substantially the same position as the bolt 63 in the vehicle width direction, and the widthwise inboard end of the lower horizontal shielding piece 72b3 is located on the inboard side of the front-left first partition panel 31A1. Furthermore, in the vehicle height direction, the distance between the upper surface of the upper horizontal shielding piece 72b1 and the lower surface of the first aisle ceiling panel 32A1 and the distance between the lower surface of the lower horizontal shielding piece 72b3 and the upper end of the front-left first partition panel 31A1 are each set to 1 to 10 mm. Therefore, the shielding member 72 essentially shields the side of the front-left first corner gap 30CG11 opposite the first passage 30A and closes the front-left first corner gap 30CG11.

[0081] Furthermore, the fastening points between the ceiling unit TU1 and the ceiling ribs 42 by the bolts 63 are covered from the first passage 30A side by the shielding upper horizontal piece 72b1 and the shielding central horizontal piece 72b2. The distance between the upper surface of the shielding upper horizontal piece 72b1 and the lower surface of the first passage ceiling panel 32A1 in the vehicle body height direction is 1 to 10 mm. Therefore, the fastening points between the ceiling unit TU1 and the ceiling ribs 42 by the bolts 63 are essentially shielded by the shielding member 72.

[0082] Incidentally, when the shielding member 72 is installed, the bolts 53 for attaching and detaching the partition unit SU to and from the ceiling frame 42 are shielded from the first passage 30A by the shielding member 72. Therefore, in this state, it is not possible to come into contact with the bolts 53. On the other hand, when the shielding member 72 is installed, the bolts 63 for attaching and detaching the ceiling unit TU1 to and from the ceiling frame 42 are shielded from the first passage 30A by the shielding member 72. Therefore, in this state, it is not possible to come into contact with the bolts 63.

[0083] However, when the shielding member 72 is installed, the screws 77 for attaching and detaching the shielding member 72 face the first passage 30A via the first front-left corner gap 30CG11 in the vehicle body width direction. Therefore, the screws 77 can be easily accessed through the first front-left corner gap 30CG11. In other words, the shielding member 72 can be easily removed from the partition unit SU.

[0084] With the shielding member 72 removed from the partition unit SU, the bolt 53 faces the first passage 30A via the first front-left corner gap 30CG11 in the vehicle body width direction, and the bolt 63 faces the first passage 30A via the first front-left corner gap 30CG11 in the vehicle body height direction. Therefore, the bolt 53 and the bolt 63 can be easily accessed through the first front-left corner gap 30CG11. In other words, the partition unit SU and the ceiling unit TU1 can be easily removed from the ceiling frame 42.

[0085] Furthermore, even after removing the partition unit SU or the ceiling unit TU1, in a state where the shielding member 72 is not installed, the partition unit SU or the ceiling unit TU1 can be easily fixed to the ceiling frame 42 with the bolts 53 or the bolts 63. Furthermore, by subsequently fixing the shielding member 72 to the partition unit SU with the screws 77, the original installation state can be restored.

[0086] In addition, the distance in the vehicle width direction between the outer edge (the outer width end of the vehicle) of the first aisle ceiling panel 32A1 in the second embodiment and the inner width surface of the front left first partition panel 31A1 is longer than the distance in the vehicle width direction between the outer edge (the outer width end of the vehicle) of the first aisle ceiling panel 32A1 in the third embodiment described below and the inner width surface of the front left first partition panel 31A1.

[0087] As described above, the vehicle 1 according to the second embodiment includes the front left first partition panel 31A1 and the first passage ceiling panel 32A1 that partition the first passage 30A of the rear platform R2, and the ceiling frame 42 supported by the roof structure, and an end of the front left first partition panel 31A1 and an end of the first passage ceiling panel 32A1 are arranged at the front left first corner 30C11 of the first passage 30A, and the ceiling frame 42 has a flat vertical piece 42a that is parallel to the vehicle body height direction and a flat horizontal piece 42b that is bent at a substantially right angle from the upper end of the vertical piece 42a, and the vertical piece 42a is The vertical piece 42a is arranged on the back side of the front-left first partition panel 31A1, which is connected to the first passage 30A, and the horizontal piece 42b is arranged on the back side of the first passage ceiling panel 32A1, which is connected to the first passage 30A. The front-left first partition panel 31A1 is removably fixed to the vertical piece 42a by a bolt 53 and a floating nut 54 (partition panel fixing device) via a partition joining member 51 joined to the front-left first partition panel 31A1, and the first passage ceiling panel 32A1 is directly removably fixed to the horizontal piece 42b by a bolt 63 and a floating nut 64 (ceiling panel fixing device). The front-left first partition panel 31A1 is detachably fixed to the vertical piece 42a via a partition joint member 51 with a bolt 53 and a floating nut 54 (partition panel fastener), and the first aisle ceiling panel 32A1 is detachably fixed directly to the horizontal piece 42b with a bolt 63 and a floating nut 64 (ceiling panel fastener). Therefore, the first aisle ceiling panel 32A1 can be removed without removing the front-left first partition panel 31A1, and the front-left first partition panel 31A1 can be removed without removing the first aisle ceiling panel 32A1. In other words, both the front-left first partition panel 31A1 and the first aisle ceiling panel 32A1 can be easily removed.

[0088] Furthermore, in the vehicle 1 according to the second embodiment, a front-left first corner gap 30CG11 is formed between an end of the front-left first partition panel 31A1 and an end of the first passage ceiling panel 32A1 at the front-left first corner 30C11 of the first passage 30A, and a shielding member 72 is disposed in the front-left first corner gap 30CG11 to shield the side of the front-left first corner gap 30CG11 opposite the first passage 30A. This prevents the side of the first passage 30A opposite the first passage 30A from being exposed through the front-left first corner gap 30CG11 of the front-left first corner 30C11 of the first passage 30A. This prevents a deterioration in the aesthetic appearance of the interior of the rear platform R2.

[0089] Furthermore, in the vehicle 1 of the second embodiment, the upper horizontal shielding piece 72b1, the central horizontal shielding piece 72b2, and the lower horizontal shielding piece 72b3 that constitute the shielding member 72 simulate air conditioning louvers, and the screws 77 are shielded by the central horizontal shielding piece 72b2 and the lower horizontal shielding piece 72b3, thereby preventing a decrease in the aesthetic appearance of the interior of the rear entry / exit platform R2.

[0090] Furthermore, in the vehicle 1 according to the second embodiment, the distance in the vehicle width direction between the outer edge (the outer-side edge in the width direction) of the first aisle ceiling panel 32A1 and the inner-side surface of the front-left first partition panel 31A1 is shorter than the distance in the vehicle width direction between the outer edge (the outer-side edge in the width direction) of the first aisle ceiling panel 32A1 and the inner-side surface of the front-left first partition panel 31A1 in the third embodiment described below. This prevents a decrease in the aesthetic appearance of the interior of the rear access platform R2.

[0091] Third Embodiment Next, a vehicle 1 according to a third embodiment of the present invention will be described. In the following, the third embodiment will be mainly described with respect to differences from the first and second embodiments. Furthermore, the same reference numerals and terms will be used for the same or similar corresponding configurations as those in the first and second embodiments.

[0092] 6 is a simplified partial cross-sectional schematic diagram showing the fastening structure of the front-left first partition panel 31A1 and the first aisle ceiling panel 32A1 according to the third embodiment, and the shielding structure of the front-left first corner gap 30CG11, taken along the line XX in FIGS. 2 and 3. In FIG. 6, the left-right direction corresponds to the vehicle body width direction, and the up-down direction corresponds to the vehicle body height direction. The vehicle body width direction is also the "direction perpendicular to the partition panel extension direction."

[0093] 6, the partition unit SU including the front-left first partition panel 31A1 and the ceiling unit TU2 including the first passage ceiling panel 32A1 are each independently detachably fixed to the ceiling frame 43. A shielding member 73 is disposed in the front-left first corner gap 30CG11 formed in the front-left first corner 30C11, and the shielding member 73 shields the front-left first corner gap 30CG11 on the side opposite to the first passage 30A.

[0094] Like the ceiling ribs 41 of the first embodiment, the ceiling ribs 43 have a plate-like vertical piece 43a that extends vertically with a constant width (a constant length in the longitudinal direction of the car body) and a plate-like horizontal piece 43b that is bent at a substantially right angle from the upper end of the vertical piece 43a toward the inside of the car in the width direction (to the left in FIG. 6). However, the length of the vertical piece 43a in the car body height direction according to the third embodiment is longer than the length of the vertical piece 41a in the car body height direction according to the first embodiment and the vertical piece 42a in the car body height direction according to the second embodiment. This is because, as will be described later, the ceiling unit TU2 includes a ceiling joint member 61 that was not included in the ceiling unit TU1 of the first embodiment or the second embodiment.

[0095] The structure of the partition unit SU is the same as that of the first and second embodiments. Furthermore, the fixing structure between the partition unit SU and the ceiling ribs 43 is the same as the fixing structure between the partition unit SU and the ceiling ribs 41, 42 according to the first and second embodiments. Therefore, the partition unit SU is detachably fixed to the ceiling ribs 43.

[0096] The ceiling unit TU2 includes a first passage ceiling panel 32A1 and a ceiling joint member 61.

[0097] The ceiling joint member 61 extends over the entire length of the first aisle ceiling panel 32A1 in the longitudinal direction of the car body. A cross section perpendicular to the longitudinal direction of the ceiling joint member 61 is generally Z-shaped. In this cross section, the ceiling joint member 61 has a plate-shaped first horizontal ceiling piece 61a parallel to the car body width direction, a plate-shaped second horizontal ceiling piece 61b parallel to the car body width direction, and a plate-shaped vertical ceiling piece 61c parallel to the car body height direction.

[0098] The first ceiling horizontal piece 61a is disposed higher than the second ceiling horizontal piece 61b. The first ceiling horizontal piece 61a is bent at a substantially right angle from the upper end of the vertical ceiling piece 61c toward the vehicle exterior in the width direction, and the second ceiling horizontal piece 61b is bent at a substantially right angle from the lower end of the vertical ceiling piece 61c toward the vehicle interior in the width direction.

[0099] The first aisle ceiling panel 32A1 is joined to the lower surface of the second ceiling horizontal piece 61b at its end on the vehicle outer side in the width direction. The second ceiling horizontal piece 61b and the first aisle ceiling panel 32A1 are fastened together with screws 65. In this joined state, the first ceiling horizontal piece 61a is positioned on the vehicle outer side in the width direction with respect to the outer edge of the first aisle ceiling panel 32A1.

[0100] The ceiling unit TU2 is fixed to the ceiling frame 43 with a ceiling joint member 61. In detail, a first ceiling horizontal piece 61a of the ceiling unit TU2 is fixed to the lower surface of the horizontal piece 43b of the ceiling frame 43 via a spacer 62. This fixing is performed by fastening with a bolt 63 inserted into the first ceiling horizontal piece 61a and horizontal piece 43b from the first passage 30A side, and a floating nut 64 arranged on the side of the horizontal piece 43b opposite the first passage 30A. In other words, the ceiling unit TU2 is detachably fixed to the ceiling frame 43.

[0101] The first ceiling horizontal piece 61a and the horizontal piece 43b are fixed at approximately the center of the first ceiling horizontal piece 61a in the width direction and the inboard end of the horizontal piece 43b in the width direction. Therefore, the outboard end of the first ceiling horizontal piece 61a in the width direction is located further outboard than the inboard end of the horizontal piece 43b in the width direction. In addition, the outer edge of the first aisle ceiling panel 32A1 and the inboard end of the horizontal piece 43b in the width direction are in approximately the same position in the car body width direction.

[0102] The shielding member 73 is installed in the front-left first corner gap 30CG11. The shielding member 73 shields the side of the front-left first corner gap 30CG11 opposite the first passage 30A. In other words, the shielding member 73 prevents the side opposite the first passage 30A from being exposed through the front-left first corner gap 30CG11. The shielding member 73 extends over the entire length of the first passage ceiling panel 32A1 in the vehicle body longitudinal direction, and includes a lower shielding member 731 and an upper shielding member 732.

[0103] The cross section orthogonal to the longitudinal direction of lower shielding member 731 is generally Z-shaped. Lower shielding member 731 is made of a single metal plate, and in this cross section has a plate-shaped lower shielding horizontal piece 731a parallel to the vehicle body width direction, a plate-shaped lower shielding first vertical piece 731b parallel to the vehicle body height direction, a plate-shaped lower shielding second vertical piece 731c parallel to the vehicle body height direction, and a lower leaf spring portion 731d.

[0104] The lower shielding first vertical piece 731b is positioned on the vehicle outer side in the width direction than the lower shielding second vertical piece 731c. The lower shielding first vertical piece 731b is bent downward at approximately a right angle from the end of the lower shielding horizontal piece 731a on the vehicle outer side in the width direction. On the other hand, the lower shielding second vertical piece 731c is bent upward at approximately a right angle from the end of the lower shielding horizontal piece 731a on the vehicle inner side in the width direction. Note that the length of the lower shielding first vertical piece 731b in the vehicle body height direction is longer than the length of the lower shielding second vertical piece 731c in the vehicle body height direction. The lower leaf spring portion 731d is provided on the upper surface side of the lower shielding horizontal piece 731a and in the vicinity of the lower shielding second vertical piece 731c. An upper shielding horizontal piece 732a of an upper shielding member 732 (described later) is inserted between the lower leaf spring portion 731d and the lower shielding horizontal piece 731a from the vehicle outer side in the width direction. The upper shielding horizontal piece 732a is sandwiched between the lower leaf spring portion 731d and the lower shielding horizontal piece 731a.

[0105] The cross section orthogonal to the longitudinal direction of the upper shielding member 732 is generally L-shaped. The upper shielding member 732 is made of a single metal plate, and in this cross section has a plate-shaped upper shielding horizontal piece 732a parallel to the width direction of the car body and a plate-shaped upper shielding vertical piece 732b parallel to the height direction of the car body. The upper shielding vertical piece 732b is bent upward at a substantially right angle from the end of the upper shielding horizontal piece 732a on the outer side of the car body in the width direction.

[0106] The upper shielding horizontal piece 732a is erected at approximately the center of the lower shielding horizontal piece 731a in the vehicle width direction, and the upper shielding horizontal piece 732a is inserted between the lower leaf spring portion 731d and the lower shielding horizontal piece 731a with the interior-side edge of the upper shielding horizontal piece 732a facing the interior-side edge of the lower shielding horizontal piece 731a in the vehicle width direction. Therefore, the first lower shielding vertical piece 731b is positioned on the exterior side of the vehicle in the width direction by approximately half the length of the lower shielding horizontal piece 731a in the vehicle width direction. The second lower shielding vertical piece 731c is positioned slightly inward in the vehicle width direction from the interior-side edge of the upper shielding horizontal piece 732a. Therefore, the lower shielding second vertical piece 731c conceals (covers) the inner-vehicle-side tip of the upper shielding horizontal piece 732a in the width direction of the vehicle body.

[0107] The shielding member 73 is fixed to the partition unit SU. More specifically, the lower first shielding vertical piece 731b of the shielding member 73 is fixed via a liner plate 76 to a portion of the partition vertical piece 51a of the partition unit SU that protrudes above the front-left first partition panel 31A1. This fixation is achieved by fastening using screws 78 inserted into the lower first shielding vertical piece 731b and the partition vertical piece 51a from the first passage 30A side, and a floating nut (not shown) arranged on the side of the partition vertical piece 51a opposite the first passage 30A side. The inside-side tip of the screw 78 in the width direction is accessible from the first passage 30A through the front-left first corner gap 30CG11.

[0108] When the shielding member 73 is fixed to the partition unit SU, the surface of the upper shielding vertical piece 732b on the vehicle's inner side in the width direction is in close contact with the surface of the ceiling vertical piece 61c on the vehicle's outer side in the width direction. In addition, the surface of the lower shielding first vertical piece 731b on the vehicle's outer side in the width direction is in close contact with the surface of the partition vertical piece 51a on the vehicle's inner side in the width direction via the liner plate 76. Therefore, the shielding member 73 closes the opposite side of the first passage 30A across the front left first corner gap 30CG11.

[0109] Additionally, the fixing points between the ceiling unit TU2 and the ceiling frame 43 by the bolts 63 are shielded from the first passage 30A by the upper shielding vertical piece 732b, the lower shielding horizontal piece 731a, and the lower shielding first vertical piece 731b.

[0110] Although not shown, in the longitudinal direction of the vehicle body, the positions of the screws 78 and the bolts 53 do not overlap, and the bolts 53 are covered by the lower shielding first vertical piece 731b. In other words, the fixing points of the partition unit SU and the ceiling frame 43 by the bolts 53 are shielded from the first passage 30A side by the lower shielding first vertical piece 731b.

[0111] Furthermore, the screw 65 is covered by the lower shielding horizontal piece 731a from below in the height direction of the car body, and the lower shielding second vertical piece 731c is disposed on the vehicle interior side in the width direction of the screw 65. Therefore, the screw 65 is hidden from the first passage 30A side by the shielding member 73. The distance between the upper end of the lower shielding second vertical piece 731c and the first passage ceiling panel 32A1 is set to, for example, 3 to 10 mm.

[0112] Here, when the shielding member 73 is installed, the bolt 53 for attaching and detaching the partition unit SU to and from the ceiling frame 43 is covered by the lower first shielding vertical piece 731b of the shielding member 73. Therefore, in this state, it is impossible to contact the bolt 53. On the other hand, when the shielding member 73 is installed, the bolt 63 for attaching and detaching the ceiling unit TU2 to and from the ceiling frame 43 is located on the opposite side of the first passage 30A via the front left first corner gap 30CG11, and the front left first corner gap 30CG11 is blocked by the shielding member 73. Therefore, in this state, it is impossible to contact the bolt 63.

[0113] However, when the shielding member 73 is installed, the screws 78 for attaching and detaching the shielding member 73 face the first passage 30A via the first front-left corner gap 30CG11 in the vehicle body width direction. Therefore, the screws 78 can be easily accessed through the first front-left corner gap 30CG11. In other words, the shielding member 73 can be easily removed from the partition unit SU.

[0114] With the shielding member 73 removed from the partition unit SU, the bolt 53 faces the first passage 30A via the first front-left corner gap 30CG11 in the vehicle body width direction, and the bolt 63 faces the first passage 30A via the first front-left corner gap 30CG11 in the vehicle body height direction. Therefore, the bolt 53 and the bolt 63 can be easily accessed through the first front-left corner gap 30CG11. In other words, the partition unit SU and the ceiling unit TU2 can be easily removed from the ceiling frame 43.

[0115] Furthermore, even after removing the partition unit SU or the ceiling unit TU2, in a state where the shielding member 73 is not installed, the partition unit SU or the ceiling unit TU2 can be easily fixed to the ceiling frame 43 with the bolts 53 or the bolts 63. Furthermore, by subsequently fixing the shielding member 73 to the partition unit SU with the screws 78, the original installation state can be restored.

[0116] As described above, the vehicle 1 according to the third embodiment includes the front-left first partition panel 31A1 and the first-passage ceiling panel 32A1 that partition the first passage 30A of the rear platform R2, and the ceiling frame 43 that is supported by the roof structure, and an end of the front-left first partition panel 31A1 and an end of the first-passage ceiling panel 32A1 are arranged at the front-left first corner 30C11 of the first passage 30A, and the ceiling frame 43 has a flat vertical piece 43a that is parallel to the vehicle body height direction and a flat horizontal piece 43b that is bent at a substantially right angle from the upper end of the vertical piece 43a, and the vertical piece 43a is arranged to define the front-left first partition panel 31A1 relative to the first passage 30A. The horizontal piece 43b is arranged on the back side of the first aisle ceiling panel 32A1 relative to the first aisle 30A, the front left first partition panel 31A1 is removably fixed to the vertical piece 43a by a bolt 53 and a floating nut 54 (partition panel fixing device) via a partition joint member 51 joined to the front left first partition panel 31A1, and the first aisle ceiling panel 32A1 is removably fixed to the horizontal piece 43b by a bolt 63 and a floating nut 64 (ceiling panel fixing device) via a ceiling joint member 61 joined to the first aisle ceiling panel 32A1. The front-left first partition panel 31A1 is detachably fixed to the vertical piece 43a via a partition joint member 51 with a bolt 53 and a floating nut 54 (partition panel fastener), and the first aisle ceiling panel 32A1 is detachably fixed to the horizontal piece 43b via a ceiling joint member 61 with a bolt 63 and a floating nut 64 (ceiling panel fastener). Therefore, the first aisle ceiling panel 32A1 can be removed without removing the front-left first partition panel 31A1, and the front-left first partition panel 31A1 can be removed without removing the first aisle ceiling panel 32A1. In other words, both the front-left first partition panel 31A1 and the first aisle ceiling panel 32A1 can be easily removed.

[0117] Furthermore, in the vehicle 1 according to the third embodiment, a front-left first corner gap 30CG11 is formed between an end of the front-left first partition panel 31A1 and an end of the first passage ceiling panel 32A1 at the front-left first corner 30C11 of the first passage 30A, and a shielding member 73 is disposed in the front-left first corner gap 30CG11 to shield the side of the front-left first corner gap 30CG11 opposite the first passage 30A. This prevents the side of the first passage 30A opposite the first passage 30A from being exposed through the front-left first corner gap 30CG11 of the front-left first corner 30C11 of the first passage 30A. This prevents a deterioration in the aesthetic appearance of the interior of the rear platform R2.

[0118] Furthermore, in the vehicle 1 according to the third embodiment, the lower shielding member 731 and the upper shielding member 732 that constitute the shielding member 73 are formed by bending a single metal plate. This prevents an increase in the cost of the vehicle 1. Furthermore, in the vehicle 1 according to the third embodiment, the distance in the vehicle width direction between the outer edge (the outer-side edge in the width direction) of the first aisle ceiling panel 32A1 and the inner-side surface of the front-left first partition panel 31A1 is longer than the distance in the vehicle width direction between the outer edge (the outer-side edge in the width direction) of the first aisle ceiling panel 32A1 and the inner-side surface of the front-left first partition panel 31A1 in the first and second embodiments. This reduces the time required for inspection of the side opposite the first front-left corner 30C11 of the first aisle 30A and for installation of the front-left first partition panel 31A1 and the first aisle ceiling panel 32A1.

[0119] (Variation) The present invention has been described above based on the first to third embodiments. These embodiments are merely examples, and it will be understood by those skilled in the art that various modifications are possible in the combination of the respective components, and that such modifications are also within the scope of the present invention.

[0120] For example, in the first to third embodiments, the partition panel 31 is removably fixed to the ceiling ribs 41 to 43 via the partition joint member 51, but it may also be removably fixed directly to the ceiling ribs 41 to 43 like the ceiling panel 32 in the first embodiment.

[0121] In the first to third embodiments, shielding members 71 to 73 are arranged in each corner gap 30CG1 to 30CG4, but it is also possible to position the end of the partition panel 31 and the end of the ceiling panel 32 as close as possible to each other so as not to arrange members such as shielding members 71 to 73 that shield the side opposite the passage 30 via each corner gap 30CG1 to 30CG4.

[0122] In the first to third embodiments, the shielding members 71 to 73 are detachably fixed to the partition unit SU, but they may also be detachably fixed to the ceiling units TU1 and TU2. In this case, from the viewpoint of preventing a decrease in aesthetic appeal, it is preferable to detachably fix the shielding members 71 to 73 to the ceiling joint member 61 rather than the ceiling panel 32. Furthermore, the shielding members 71 to 73 may also be detachably fixed to both the partition unit SU and the ceiling units TU1 and TU2.

[0123] In the first embodiment, using Figure 4, in the second embodiment, using Figure 5, and in the third embodiment, using Figure 6, the fixing structure of the front left first partition panel 31A1 and the first aisle ceiling panel 32A1, and the shielding structure related to the front left first corner gap 30CG11 have been described, but these fixing structures and shielding structures are also applied to the fixing structures of the other front left partition panels 31A (partition panels 31A2 to 31A5) and other aisle ceiling panels 32A (second aisle ceiling panel 32A2 to fifth aisle ceiling panel 32A5), and the shielding structures related to the other front left corner gaps 30CG1 (front left second corner gap 30CG12 to front left fifth corner gap 30CG15). Furthermore, the fixing structure and the shielding structure are also applied to the fixing structures of other partition panels 31 (partition panels 31B to 31D) and other aisle ceiling panels 32A (second aisle ceiling panel 32A2 to seventh aisle ceiling panel 32A7), as well as to the shielding structures related to other corner gaps 30CG (front right corner gap 30CG2, rear left corner gap 30CG3, rear right corner gap 30CG4).

[0124] The shape and structure of the shielding members 71 to 73 may be modified as appropriate within the scope that can prevent passengers and the like in the aisle 30 from being able to see the corner gap on the side opposite to the aisle 30. [Explanation of symbols]
