Description

Technical Field

[0001] The present invention relates to a railway vehicle including a partition panel facing a passage of an access platform and a ceiling panel.

Background Art

[0002] Generally, in the access platform (deck) of a railway vehicle, the space used for in-vehicle facilities such as a multi-purpose room, a machinery room, a toilet, and a washbasin has been partitioned in a manner separated from the passage by a partition panel. In the railway vehicle described in Patent Document 1, the space used for in-vehicle facilities is partitioned by assembling an individual compartment structure that has been outsourced separately from the on-site work performed on the vehicle body to the vehicle.

[0003] By the way, the applicant has conventionally installed a partition panel on the floor surface to partition the space used for in-vehicle facilities. And, as a method of installing the partition panel, there are a method of first fixing the ceiling panel to the ceiling side and then fixing the partition panel to the ceiling panel (conventional installation method 1), and a method of first fixing the partition panel to the ceiling side and then fixing the ceiling panel to the partition panel (conventional installation method 2).

[0004] FIG. 6(A) is a schematic partial cross-sectional view showing a fixing structure of a partition panel and a ceiling panel according to the conventional installation method 1, and FIG. 6(B) is a schematic partial cross-sectional view showing a fixing structure of a partition panel and a ceiling panel according to the conventional installation method 2.

[0005] According to the conventional installation method 1, as shown in FIG. 6(A), the ceiling panel 32 is fixed to the ceiling frame 40 supported by the roof structure via the spacer 81 with bolts 80 at the outer end in the vehicle body width direction. Also, 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 vertically downward from the inner end in the vehicle body width direction of one straight portion. Further, the partition panel 31 is joined to the receiving member 84 at the back on the vehicle outer side in the vehicle body width direction at the upper end. And, the receiving member 84 is fastened to the other straight portion of the connecting member 82 with a bolt 86 via a liner plate 85. As a result, the partition panel 31 is disposed at a position that enters inside from the vehicle outer side tip in the vehicle body width direction of the ceiling panel 32 and is installed at a predetermined distance below the ceiling panel 32. That is, a gap S8 is formed between the ceiling panel 32 and the upper end of the partition panel 31. However, the space between the bolt 80 and the gap S8 is blocked 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 the conventional installation method 2, as shown in FIG. 6(B), the partition panel 31 is fixed to the ceiling joist 40 supported by the roof structure via the spacer 91 by bolts 90 on the outside of the vehicle body in the vehicle width direction at the upper end. Also, a connecting member 92 having 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 inward of the vehicle body in the vehicle width direction from the lower end of one straight portion. On the other hand, the ceiling panel 32 is fastened by screws 93 to one of the mutually parallel straight portions of the receiving member 94 having a Z-shaped cross section at the outside end of the vehicle body in the vehicle width direction. The other of the mutually parallel straight portions of the receiving member 94 is fastened by bolts 96 to the other straight portion of the connecting member 92 via the liner plate 95. As a result, the ceiling panel 32 is disposed below the upper end of the partition panel 31 and is installed at a predetermined distance inward of the vehicle body in the vehicle width direction from the partition panel 31. That is, a gap S9 is formed between the partition panel 31 and the inner end of the ceiling panel 32 in the vehicle width direction. However, the space between the bolt 90 and the gap S9 is blocked by the connecting member 92 and the receiving member 94. Therefore, when 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 bolt 90 to remove the partition panel 31.

FIG. 1 is a schematic view of the railway vehicle (hereinafter referred to as "vehicle") according to the first embodiment of the present invention as seen from the inner side of the vehicle in plan view. In the longitudinal direction of the vehicle body (vehicle longitudinal direction) constituting the vehicle 1, for the sake of convenience, assuming the situation of traveling to the right side in FIG. 1, the right side where the vehicle 1 travels is referred to as the "front side", and the left side opposite to the traveling side is referred to as the "rear side" for explanation. Also, in FIG. 1, the right side is the front side and the left side is the rear side. Further, in the vehicle width direction of the vehicle body constituting the vehicle 1, the right side and the left side facing from the rear side to the front side in the vehicle longitudinal direction are referred to as the "right side" and the "left side", respectively. In FIG. 1, the lower side is the right side and the upper side is the left side.

[0016] The vehicle 1 will be described. The vehicle 1 is a limited express vehicle. The structure 10 constituting the vehicle 1 includes a frame (not shown), a pair of left and right side structures 11, a pair of front and rear roof structures 12, and a roof structure (not shown). Note that the structure 10 has a symmetric structure in the vehicle width direction. However, the structure of the structure 10 can be set as appropriate and may not be symmetric in the vehicle width direction.

[0017] Vehicle 1 has a passenger compartment RI, a rear entrance platform R2, and a front entrance platform R3. In order from the front, the front entrance platform R3, the passenger compartment R1, and the rear entrance platform R2 are arranged. The front entrance platform R3 and the passenger compartment R1 are partitioned by a front partition side wall 20. The passenger compartment R1 and the rear entrance platform R2 are partitioned by a rear partition side wall 21. The front partition side wall 20 and the rear partition side wall 21 are parallel in the vehicle body width direction in plan view. Note that Vehicle 1 may be composed of the passenger compartment R1 and the rear entrance platform R2, or may be composed of the passenger compartment R1 and the front entrance platform R3.

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

[0019] The passage 37 is partitioned by a partition panel 38 perpendicular to the floor surface. The partition panel 38 includes a first partition panel 38A and a second partition panel 38B. The first partition panel 38A is disposed on the front side and the left side of the intersection of the first passage 37A and the second passage 37B. The second partition panel 38B is disposed on the front side and the right side 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 include a straight line portion (first straight line portion) that faces and partitions the first passage 37A in the vehicle body width direction, a straight line portion (second straight line portion) that faces and partitions the second passage 37B in the vehicle body longitudinal direction, and a corner portion that connects the first straight line portion and the second straight line portion in an arc shape.

[0021] On the rear access platform R2, a passage 30 having a substantially cross-shaped configuration in plan view is formed. The passage 30 has a first passage 30A parallel to the longitudinal direction of the vehicle body and a second passage 30B parallel to the width direction of the vehicle body. The first passage 30A is formed at the center in the width direction of the vehicle body of the rear access platform R2. The second passage 30B is formed on the rear side of the center in the longitudinal direction of the vehicle body of the rear access platform R2. Note that the shape of the passage 30 formed in the rear access platform R2 is not limited to a substantially cross-shaped configuration in plan view and may be changed as appropriate. For example, the shape of the passage 30 may be a substantially T-shaped configuration or a substantially L-shaped configuration 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 substantially linear in plan view, the passage 30 may be formed on one side in the width direction of the vehicle body of the rear access platform R2 or at the center in the width direction of the vehicle body of the rear access platform R2.

[0022] The passage 30 is partitioned by a partition panel 31 perpendicular to the floor surface. The partition panel 31 includes 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 disposed on the front side and the left side of the intersection of the first passage 30A and the second passage 30B. The front right partition panel 31B is disposed on the front side and the right side of the intersection of the first passage 30A and the second passage 30B. The rear left partition panel 31C is disposed on the rear side and the left side of the intersection of the first passage 30A and the second passage 30B. The rear right partition panel 31D is disposed on the rear side and the right side of the intersection of the first passage 30A and the second passage 30B.

[0023] 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 each include a straight portion (first straight portion) facing the first passage 30A in the width direction of the vehicle body, that is, partitioning the first passage 30A, a straight portion (second straight portion) facing the second passage 30B in the longitudinal direction of the vehicle body, that is, partitioning the second passage 30B, and a corner portion connecting the first straight portion and the second straight portion in a substantially right angle and in an arc shape.

[0024] In addition, spaces are formed on the side opposite to the passage 30 (the outside of the vehicle) 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. And a multipurpose room R24 is installed on the side opposite to the passage 30 (the outside of the vehicle) of the front left partition panel 31A. Similarly, on the side opposite to the passage 30 (the outside of the vehicle) of the front right partition panel 31B, a washbasin R21, a toilet R22, and a machine room R23 are installed in order from the front side.

[0025] Next, the rear access platform R2 will be described in detail by digging down. FIG. 2 is a schematic diagram mainly showing the allocation of the ceiling panel 32 in the rear access platform R2. In the rear access platform R2, a ceiling panel 32 for partitioning the indoor space of the rear access platform R2 is installed. The ceiling panel 32 includes a passage ceiling panel 32A facing the passage 30 in the vertical direction of the vehicle body, and an equipment ceiling panel 32B facing the floor surface (not shown) on the side opposite to the passage 30 of the partition panel 31.

[0027] The passage ceiling panel 32A is generally formed in a substantially cross shape that is the same as the passage 30 in plan view. However, in plan view, the passage ceiling panel 32A is generally slightly smaller than the passage 30 as a whole. Also, the passage ceiling panel 32A is integrally composed of a plurality of parts, specifically, a first passage ceiling panel 32A1, a second passage ceiling panel 32A2, a third passage ceiling panel 32A3, a fourth passage ceiling panel 32A4, a fifth passage ceiling panel 32A5, a sixth passage ceiling panel 32A6, and a seventh passage ceiling panel 32A7.

[0028] The ceiling panel 32A1 for the first passage, the ceiling panel 32A2 for the second passage, and the ceiling panel 32A3 for the third passage are arranged between the front left partition panel 31A and the front right partition panel 31B in plan view and face the first passage 30A. Also, the ceiling panel 32A1 for the first passage, the ceiling panel 32A2 for the second passage, and the ceiling panel 32A3 for the third passage are arranged side by side without gaps in the front-rear direction. Relatively, the ceiling panel 32A1 for the first passage is arranged at the most front side, and the ceiling panel 32A3 for the third passage is arranged at the most rear side. And the ceiling panel 32A2 for the second passage is connected to each of the ceiling panel 32A1 for the first passage arranged at the front side and the ceiling panel 32A3 for the third passage arranged at the rear side.

[0029] The ceiling panel 32A4 for the fourth passage is arranged between the rear left partition panel 31C and the rear right partition panel 31D in plan view and faces the first passage 30A. The ceiling panel 32A5 for the fifth passage is arranged between the front left partition panel 31A and the rear left partition panel 31C in plan view and faces the second passage 30B. The ceiling panel 32A6 for the sixth passage is arranged between the front right partition panel 31B and the rear right partition panel 31D in plan view and faces the second passage 30B.

[0031] Also, portions other than the connection portions of the ceiling panel 32A7 for the seventh passage with the ceiling panel 32A3 for the third passage, the ceiling panel 32A4 for the fourth passage, the ceiling panel 32A5 for the fifth passage, and the ceiling panel 32A6 for the sixth passage face 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 plan view.

[0032] The ceiling panel 32A1 for the first passage, the ceiling panel 32A2 for the second passage, the ceiling panel 32A3 for the third passage, the ceiling panel 32A4 for the fourth passage, the ceiling panel 32A5 for the fifth passage, and the ceiling panel 32A6 for the sixth passage are formed in a rectangular shape in plan view. Also, the connection portions of the ceiling panel 32A7 for the seventh passage with the ceiling panel 32A3 for the third passage, the ceiling panel 32A4 for the fourth passage, the ceiling panel 32A5 for the fifth passage, and the ceiling panel 32A6 for the sixth passage are formed in a straight line. On the other hand, portions other than the connection portions of the ceiling panel 32A7 for the seventh passage with the ceiling panel 32A3 for the third passage, the ceiling panel 32A4 for the fourth passage, the ceiling panel 32A5 for the fifth passage, and the ceiling panel 32A6 for the sixth passage are 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.

[0033] The lengths in the vehicle body width direction of the ceiling panel 32A1 for the first passage, the ceiling panel 32A2 for the second passage, the ceiling panel 32A3 for the third passage, and the ceiling panel 32A4 for the fourth passage are shorter than the length in the vehicle body width direction of the first passage 30A. And the ceiling panel 32A1 for the first passage, the ceiling panel 32A2 for the second passage, the ceiling panel 32A3 for the third passage, and the ceiling panel 32A4 for the fourth passage are equally allocated to the first passage 30A in the vehicle body width direction in plan view. Therefore, in plan view, between each of the ceiling panel 32A1 for the first passage, the ceiling panel 32A2 for the second passage, and the ceiling panel 32A3 for the third passage and the front left partition panel 31A, between each of the ceiling panel 32A1 for the first passage, the ceiling panel 32A2 for the second passage, and the ceiling panel 32A3 for the third passage and the front right partition panel 31B, between the ceiling panel 32A4 for the fourth passage and the rear left partition panel 31C, and between the ceiling panel 32A4 for the fourth passage and the rear right partition panel 31D, gaps of the same width along the vehicle body longitudinal direction are formed.

[0034] Hereinafter, the gaps between each of the ceiling panel 32A1 for the first passage, the ceiling panel 32A2 for the second passage, and the ceiling panel 32A3 for the third passage and the front left partition panel 31A are referred to as "front left first gap AT11", "front left second gap AT12", and "front left third gap AT13". The front left first gap AT11, the front left second gap AT12, and the front left third gap AT13 communicate with each other. Also, the gaps between each of the ceiling panel 32A1 for the first passage, the ceiling panel 32A2 for the second passage, and the ceiling panel 32A3 for the third passage and the front right partition panel 31B are referred to as "front right first gap AT21", "front right second gap AT22", and "front right third gap AT23". The front right first gap AT21, the front right second gap AT22, and the front right third gap AT23 communicate with each other. Furthermore, the gaps between the ceiling panel 32A4 for the fourth passage and each of the rear left partition panel 31C and the rear right partition panel 31D are referred to as "rear left first gap AT31" and "rear right first gap AT41".

[0035] Note that the vehicle body width direction lengths (widths) related to the front left first gap AT11, the front left second gap AT12, and the front left third gap AT13, the vehicle body width direction lengths (widths) related to the front right first gap AT21, the front right second gap AT22, and the front right third gap AT23, the vehicle body width direction length (width) related to the rear left first gap AT31, and the vehicle body width direction length (width) related to the rear right first gap AT41 are the same.

[0036] The vehicle body longitudinal lengths of the ceiling panel 32A5 for the fifth passage and the ceiling panel 32A6 for the sixth passage are shorter than the vehicle body longitudinal length of the second passage 30B. And the ceiling panel 32A5 for the fifth passage and the ceiling panel 32A6 for the sixth passage are equally allocated with respect to the second passage 30B in the vehicle body longitudinal direction in plan view. Therefore, in plan view, between the ceiling panel 32A5 for the fifth passage and the front left partition panel 31A, between the ceiling panel 32A5 for the fifth passage and the rear left partition panel 31C, between the ceiling panel 32A6 for the sixth passage and the front right partition panel 31B, and between the ceiling panel 32A6 for the sixth passage and the rear right partition panel 31D, gaps of the same width along the vehicle body width direction are formed.

[0037] Hereinafter, the gaps between the ceiling panel 32A5 for the fifth passage and each of the front left partition panel 31A and the rear left partition panel 31C are referred to as the "front left fifth gap AT15" and the "rear left third gap AT33". Also, the gaps between the ceiling panel 32A6 for the sixth passage and each of the front right partition panel 31B and the rear right partition panel 31D are referred to as the "front right fifth gap AT25" and the "rear right third gap AT43".

[0038] Note that the vehicle body longitudinal length (width) of the front left fifth gap AT15, the front right fifth gap AT25, the rear left third gap AT33, and the rear right third gap AT43 is the same as the vehicle body width direction length (width) such as the front left first gap AT11.

[0039] Also, in plan view, between the ceiling panel 32A7 for the seventh passage and each 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, gaps of the same width are formed along the arc-shaped corner portions of each partition panel 31A, 31B, 31C, 31D in plan view.

[0040] Hereinafter, the gaps between the ceiling panel 32A7 for the seventh passage and each 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 are referred to as the "front left fourth gap AT14", the "front right fourth gap AT24", the "rear left second gap AT32", and the "rear right second gap AT42".

[0041] Note that the length (width) orthogonal to the extending direction in plan view related to the front left fourth gap AT14 (that is, in the curvature radius direction of each corner portion), the length (width) orthogonal to the extending direction in plan view related to the front right fourth gap AT24, the length (width) orthogonal to the extending direction in plan view related to the rear left second gap AT32, and the length (width) orthogonal to the extending direction in plan view related to the rear right second gap AT42 are the same as the vehicle body width direction length (width) such as the front left first gap AT11.

[0042] The front left first gap AT11, the front left second gap AT12, the front left third gap AT13, the front left fourth gap AT14, and the front left fifth gap AT15 communicate with each other. That is, in plan view, a front left gap AT1 of the same width is formed between the ceiling panel 32A for passage and the front left partition panel 31A. Similarly, the front right first gap AT21, the front right second gap AT22, the front right third gap AT23, the front right fourth gap AT24, and the front right fifth gap AT25 communicate with each other. That is, in plan view, a front right gap AT2 of the same width is formed between the ceiling panel 32A for passage and the front right partition panel 31B.

[0043] Furthermore, the rear left first gap AT31, the rear left second gap AT32, and the rear left third gap AT33 communicate with each other. That is, in plan view, a rear left gap AT3 of the same width is formed between the ceiling panel 32A for passage and the rear left partition panel 31C. Similarly, the rear right first gap AT41, the rear right second gap AT42, and the rear right third gap AT43 communicate with each other. That is, in plan view, a rear right gap AT4 of the same width is formed between the ceiling panel 32A for passage and the rear right partition panel 31D.

[0044] Also, in the rear access platform R2, above the ceiling panel 32A for passage, two ducts 34 are installed in parallel. Each duct 34 is formed along the longitudinal direction of the vehicle body. Also, each duct 34 is installed at the same distance from the center in the vehicle body width direction of the rear access platform R2 to the outside of the vehicle. The outer edge in the vehicle body width direction of each duct 34 is disposed above the straight portion (first straight portion) facing the first passage 30A of each partition panel 31A, 31B, 31C, 31D.

[0045] FIG. 3(A) is a schematic view of the front left partition panel 31A seen from approximately the center in the vehicle width direction of the first passage 30A, and FIG. 3(B) is a schematic view of the front left partition panel 31A seen from approximately the center in the vehicle longitudinal direction of the second passage 30B. The front left partition panel 31A is integrally composed of five parts along the extending direction in plan view, specifically, 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, which are arranged in order from the front side and connected to each other.

[0046] Note that each of 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 faces the ceiling panel 32A1 for the first passage, the ceiling panel 32A2 for the second passage, the ceiling panel 32A3 for the third passage, the ceiling panel 32A7 for the seventh passage, and the ceiling panel 32A5 for the fifth passage, respectively, in the direction orthogonal to each extending direction in plan view. Further, the front left first partition panel 31A1, the front left second partition panel 31A2, and the front left third partition panel 31A3 constitute the above-mentioned first straight portion, and are each formed in a flat plate shape as a whole. The front left fifth partition panel 31A5 constitutes the above-mentioned second straight portion and is formed in a flat plate shape as a whole. The front left fourth partition panel 31A4 constitutes the above-mentioned corner portion and is formed in a semi-cylindrical shape as a whole.

[0047] Further, each of 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 is formed lower than the ceiling surface of the passage ceiling panel 32A. That is, in a front view, a gap is formed between the upper end of each of 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 and the ceiling surface of the passage ceiling panel 32A. And each of these gaps is included in the aforementioned front left first gap AT11, front left second gap AT12, front left third gap AT13, front left fourth gap AT14, and front left fifth gap AT15. Therefore, a three-dimensional front left gap AT1 is formed at the corner of the passage 30 constituted by the front left partition panel 31A and the passage ceiling panel 32A.

[0048] Next, the fixing structure of the partition panel 31 facing the passage 30 and the passage ceiling panel 32A will be described. Note that the fixing structures 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, which are the partition panels 31, are the same, and the fixing structures of the first passage ceiling panel 32A1, the second passage ceiling panel 32A2, the third passage ceiling panel 32A3, the fourth passage ceiling panel 32A4, and the fifth passage ceiling panel 32A5, which are the passage ceiling panels 32A, are the same. Here, the fixing structures of the front left partition panel 31A and the first passage ceiling panel 32A1 will be described as representatives.

[0049] FIG. 4 is a schematic partial cross-sectional view simply showing the fixing structure of the front left partition panel 31A and the ceiling panel 32A1 for the first passage in the X-X cross-section of FIGS. 2 and 3. As shown in FIG. 4, at the corner 30AC of the first passage 30A formed by the front left first partition panel 31A1 and the ceiling panel 32A1 for the first passage, a partition unit SU including the front left first partition panel 31A1 and a ceiling unit TU including the ceiling panel 32A1 for the first passage are detachably fixed to the connecting member 101. The connecting member 101 is fixed to the ceiling frame 40 supported by a purlin (not shown) constituting the roof structure. Therefore, each of the partition unit SU and the ceiling unit TU is detachably fixed to the ceiling frame 40 via the connecting member 101.

[0050] The ceiling frame 40 has a plate-like vertical portion 40a extending in the vertical direction with a constant width (a constant vehicle body longitudinal length), and a plate-like horizontal portion 40b bent substantially at a right angle from the lower end portion of the vertical portion 40a toward the right side (the first passage 30A). The horizontal portion 40b is formed below the ceiling panel 32A1 for the first passage. Note that a plurality of ceiling frames 40 are installed at predetermined intervals along the vehicle body longitudinal direction.

[0051] The cross-sectional shape of the duct 34 orthogonal to the vehicle body longitudinal direction is generally substantially L-shaped as a whole. The duct 34 has an outer wall portion 34A and a bottom plate portion 34B in this cross-sectional shape. The outer wall portion 34A is formed parallel to the vertical direction on the vehicle outer side (left side) in the vehicle body width direction. The bottom plate portion 34B is formed parallel to the vehicle body width direction at substantially the same height as the lower end portion of the outer wall portion 34A. An opening 34h is formed between the vehicle outer side tip of the bottom plate portion 34B in the vehicle body width direction and the outer wall portion 34A. The opening 34h is formed over the entire vehicle body longitudinal length of the duct 34.

[0052] The connecting member 101 extends in the longitudinal direction of the vehicle body. The longitudinal length of the connecting member 101 in the vehicle body longitudinal direction is the same as the longitudinal length of the front left first partition panel 31A1 and the longitudinal length of the first passage ceiling panel 32A1 in the vehicle body longitudinal direction. The connecting member 101 is made of a single metal plate and has a substrate portion 101a, a partition side receiving portion 101b, a ceiling side receiving portion 101c, and a flange portion 101d. The substrate portion 101a is parallel to the vehicle body width direction in a cross section orthogonal to the vehicle body longitudinal direction. The partition side receiving portion 101b is bent downward at a substantially right angle from the left edge portion of the substrate portion 101a. On the other hand, the ceiling side receiving portion 101c is bent downward at a substantially right angle from the right edge portion of the substrate portion 101a. The vertical length of the partition side receiving portion 101b is longer than the vertical length of the ceiling side receiving portion 101c. Further, the flange portion 101d is bent leftward at a substantially right angle from the lower edge portion of the partition side receiving portion 101b.

[0053] The partition unit SU has a front left first partition panel 31A1 and a partition joining member 51. The partition joining member 51 extends over the entire length of the front left first partition panel 31A1 in the vehicle body longitudinal direction. Further, the cross section of the partition joining member 51 orthogonal to the vehicle body longitudinal direction has a partition first joining portion 51a in the form of a plate parallel to the vertical direction, a partition second joining portion 51b in the form of a plate parallel to the vertical direction, and a connecting portion 51c in the form of a substantially plate parallel to the vehicle body width direction, and is formed in an overall J shape. The vertical length of the partition second joining portion 51b is longer than the vertical length of the partition first joining portion 51a. Further, the partition second joining portion 51b is formed at a predetermined interval on the side opposite to the front left first partition panel 31A1 of the partition first joining portion 51a. And the partition first joining portion 51a and the partition second joining portion 51b are connected to the connecting portion 51c at their lower ends. The front left first partition panel 31A1 is joined to the right surface of the partition first joining portion 51a at the outer surface of the upper end portion.

[0054] The ceiling unit TU has a ceiling panel 32A1 for the first passage and a ceiling joining member 61. The ceiling joining member 61 extends over the entire length of the ceiling panel 32A1 for the first passage in the longitudinal direction of the vehicle body. Further, the cross section of the ceiling joining member 61 orthogonal to the longitudinal direction of the vehicle body is generally in an L shape as a whole, and has a plate-shaped ceiling first joining portion 61a parallel to the vehicle body width direction and a plate-shaped ceiling second joining portion 61b parallel to the vertical direction. The ceiling second joining portion 61b is bent upward at a substantially right angle at the left edge portion of the ceiling first joining portion 61a. The ceiling panel 32A1 for the first passage is joined to the lower surface of the ceiling first joining portion 61a on the upper surface near the left edge portion.

[0055] And the connecting member 101 is fastened by a bolt 54 inserted from below and a horizontal portion 40b of the ceiling frame 40 via a spacer 53 at a flange portion 101d. That is, the connecting member 101 is detachably fixed to the ceiling frame 40.

[0056] The partition unit SU is fastened by a bolt 56 inserted from the right side and a partition-side receiving portion 101b of the connecting member 101 via a liner plate 55 at a partition second joining portion 51b. That is, the partition unit SU is detachably fixed to the ceiling frame 40 via the connecting member 101.

[0057] The ceiling unit TU is fastened by a screw 62 inserted from the left side and a ceiling-side receiving portion 101c of the connecting member 101 at a ceiling second joining portion 61b. That is, the ceiling unit TU is detachably fixed to the ceiling frame 40 via the connecting member 101.

[0058] Also, the left front tip of the ceiling panel 32A1 for the first passage is located to the right of the front left first partition panel 31A1. On the other hand, the upper front tip of the front left first partition panel 31A1 is located below the ceiling panel 32A1 for the first passage. That is, a three-dimensional front left first gap AT11 is formed at the corner 30AC of the first passage 30A partitioned by the front left first partition panel 31A1 and the ceiling panel 32A1 for the first passage (where the front left first partition panel 31A1 and the ceiling panel 32A1 for the first passage face each other). And the front left first gap AT11 communicates with the space S1 surrounded by the substrate portion 101a, the partition side receiving portion 101b, and the ceiling side receiving portion 101c.

[0059] Here, the bolt 56 is disposed slightly above the upper end of the front left first partition panel 31A1 and faces the space S1 and the front left first gap AT11 in the vehicle body width direction. Therefore, the bolt 56 can be easily attached and detached through the front left first gap AT11 and the space S1. That is, the front left first partition panel 31A1 can be easily detached from the connecting member 101 without removing the ceiling panel 32A1 for the first passage.

[0060] On the other hand, although the screw 62 is disposed above the ceiling panel 32A1 for the first passage, it is disposed near the left edge of the ceiling panel 32A1 for the first passage and faces the space S1 in the vehicle body width direction. Therefore, the screw 62 can be easily attached and detached through the front left first gap AT11 and the space S1. That is, the ceiling panel 32A1 for the first passage can be easily detached from the connecting member 101 without removing the front left first partition panel 31A1.

[0061] In addition, with the connecting member 101 fixed to the ceiling joist 40, the substrate portion 101a faces the opening 34h of the duct 34 in the vertical direction. Further, in the range of the opening 34h of the duct 34 with respect to the substrate portion 101a in the vertical direction, a communication hole 101h communicating in the vertical direction is formed. Therefore, in the vertical direction, the inside of the duct 34 communicates with the first passage 30A through the opening 34h, the communication hole 101h, the space S1, and the front left first gap AT11.

[0062] In the first embodiment, the planar shape of the communication hole 101h is rectangular and fits within the opening 34h in plan view. Further, the communication holes 101h are arranged in parallel at predetermined intervals along the longitudinal direction of the vehicle body. And between the duct 34 and the ceiling panel 32A1 for the first passage, a left sealing member 63 and a right sealing member 64 for preventing air supplied from inside the duct 34 from leaking between the duct 34 and the ceiling panel 32A1 for the first passage are installed. The left sealing member 63 and the right sealing member 64 are formed over the entire longitudinal length of the vehicle body of the opening 34h of the duct 34. Note that the planar shape of the communication hole 101h can be set as appropriate, and may be a shape other than rectangular, such as oval or circular.

[0063] The left sealing member 63 is connected to the lower end portion of the outer wall portion 34A. A buffer member 65 is attached to the lower end of the left sealing member 63 over the entire longitudinal length of the vehicle body of the left sealing member 63. The buffer member 65 is in close contact with the upper surface of the substrate portion 101a on the left side of each communication hole 101h. On the other hand, the right sealing member 64 is connected to the left edge portion of the bottom plate portion 34B. A buffer member 66 is attached to the lower end of the right sealing member 64 over the entire longitudinal length of the vehicle body of the right sealing member 64. The buffer member 66 is in close contact with the upper surface of the substrate portion 101a on the right side of each communication hole 101h.

[0064] In the first embodiment, the ceiling unit TU and the connecting member 101 are fixed to the ceiling joist 40 in a state where they are integrated by the screws 62. In other words, the ceiling unit TU and the connecting member 101 are pre-assembled, and the pre-assembled integrated ceiling unit TU and connecting member 101 are fixed to the ceiling joist 40. In this case, although not shown in the drawings, also on the front right side first partition panel 31B1 side, similarly, by fixing the integrated ceiling unit TU and connecting member 101 to the ceiling joist 40, the integrated ceiling unit TU and connecting member 101 are supported by the roof structure via the ceiling joist 40.

[0065] Also, it is assumed that the front left side first partition panel 31A1 is appropriately fixed to the floor surface side by a known fixing structure. Therefore, the connecting member 101 is fixed to the ceiling joist 40 via the spacer 53 and is fixed to the floor surface via the partition unit SU. Therefore, even when the ceiling unit TU is removed from the connecting member 101, the connecting member 101 is stably held.

[0066] <Second Embodiment> Next, a second embodiment according to the present invention will be described. In the following, mainly, as the second embodiment, differences from the first embodiment will be described. Also, the same reference numerals and terms will be used for the same configurations or similarly corresponding configurations as those in the first embodiment.

[0067] FIG. 5 is a schematic partial cross-sectional view simply showing the fixing structure of the front left partition panel 31A and the first passage ceiling panel 32A1 in the X-X cross-section of FIGS. 2 and 3. As shown in FIG. 5, each of the partition unit SU including the front left side first partition panel 31A1 and the ceiling unit TU including a part of the first passage ceiling panel 32A1 is detachably fixed to a connecting unit RU including a part of the first passage ceiling panel 32A1. The connecting unit RU is fixed to the ceiling joist 40 supported by a rafter (not shown) of the roof structure. That is, each of the partition unit SU and the ceiling unit TU is detachably fixed to the ceiling joist 40 via the connecting unit RU.

[0068] The ceiling member 40 has a vertical portion 40a and a horizontal portion 40b, similar to the case of the first embodiment. However, the horizontal portion 40b is formed above the first passage ceiling panel 32A1.

[0069] The first passage ceiling panel 32A1 includes an inner ceiling panel 32A11 for the first passage disposed on the vehicle interior side (right side) in the vehicle width direction from the front left first partition panel 31A1 (disposed directly above the passage 30), and an outer ceiling panel 32A12 for the first passage disposed on the vehicle exterior side (left side) in the vehicle width direction from the front left first partition panel 31A1 (not disposed directly above the passage 30).

[0070] The length in the vehicle longitudinal direction and the length in the vehicle width direction of the inner ceiling panel 32A11 for the first passage are the same as the length in the vehicle longitudinal direction and the length in the vehicle width direction of the first passage ceiling panel 32A1 in the first embodiment. And the installation position of the inner ceiling panel 32A11 for the first passage is the same as the installation position of the first passage ceiling panel 32A1 in the first embodiment. Also, the inner ceiling panel 32A11 for the first passage is configured to be removable without removing the partition unit SU, similar to the first passage ceiling panel 32A1 in the first embodiment. Therefore, basically, the inner ceiling panel 32A11 for the first passage is the same as the first passage ceiling panel 32A1 in the first embodiment. However, the length in the vehicle longitudinal direction and the length in the vehicle width direction of the inner ceiling panel 32A11 for the first passage may be different from the length in the vehicle longitudinal direction and the length in the vehicle width direction of the first passage ceiling panel 32A1 in the first embodiment. In other words, the inner ceiling panel 32A11 for the first passage may be configured differently from the first passage ceiling panel 32A1 in the first embodiment.

[0071] Note that the length of the outer ceiling panel 32A12 for the first passage in the vehicle body longitudinal direction is the same as the length of the inner ceiling panel 32A11 for the first passage in the vehicle body longitudinal direction, and the length of the outer ceiling panel 32A12 for the first passage in the vehicle body width direction is shorter than the length of the inner ceiling panel 32A11 for the first passage in the vehicle body width direction. The outer ceiling panel 32A12 for the first passage is configured to be removable only when the partition unit SU is removed.

[0072] The inner ceiling panel 32A11 for the first passage and the outer ceiling panel 32A12 for the first passage are arranged side by side at a predetermined distance in the vehicle body width direction. That is, a ceiling opening 32A1h with a constant length in the vehicle body width direction is formed over the entire length of the first passage ceiling panel 32A1 in the vehicle body longitudinal direction between the inner ceiling panel 32A11 for the first passage and the outer ceiling panel 32A12 for the first passage. Therefore, in the first passage ceiling panel 32A1, the inner ceiling panel 32A11 for the first passage and the outer ceiling panel 32A12 for the first passage are completely separated in the vehicle body width direction.

[0073] Note that the left side surface (the right inner wall surface of the ceiling opening 32A1h) of the inner ceiling panel 32A11 for the first passage is located on the right side of the front left first partition panel 31A1. On the other hand, the right side surface (the left inner wall surface of the ceiling opening 32A1h) of the outer ceiling panel 32A12 for the first passage is located near the upper part of the front left first partition panel 31A1.

[0074] The connecting unit RU extends in the vehicle body longitudinal direction. The connecting unit RU includes a first connecting member 201, a second connecting member 202, and the outer ceiling panel 32A12 for the first passage. The fact that the outer ceiling panel 32A12 for the first passage is included in the connecting unit RU means that the part (the outer ceiling panel 32A12 for the first passage) that cannot be detached unless the partition unit SU is removed in the first passage ceiling panel 32A1 has a function of fixing the part (the inner ceiling panel 32A11 for the first passage) that can be detached without removing the partition unit SU in the first passage ceiling panel 32A1 to the ceiling frame 40.

[0075] The first connecting member 201 connects the first outer ceiling panel 32A12 for the first passage and the ceiling unit TU. The first connecting member 201 extends in the longitudinal direction of the vehicle body as a whole. The length of the first connecting member 201 in the longitudinal direction of the vehicle body is the same as the length of the first partition panel 31A1 on the front left side in the longitudinal direction of the vehicle body and the length of the first outer ceiling panel 32A1 in the longitudinal direction of the vehicle body. The first connecting member 201 has a first receiving portion 201a, a first joint portion 201b, and a first pushing-up portion 201c.

[0076] The first receiving portion 201a and the first joint portion 201b are parallel to each other in the vehicle body width direction in a cross section perpendicular to the longitudinal direction of the vehicle body. The first receiving portion 201a is located above the first joint portion 201b. Also, the first receiving portion 201a is located to the right of the first joint portion 201b. Specifically, the position of the left edge portion of the first receiving portion 201a in the vehicle body width direction is the same as the position of the right edge portion of the first joint portion 201b in the vehicle body width direction. The first pushing-up portion 201c is bent substantially at a right angle downward from the left edge portion of the first receiving portion 201a and bent substantially at a right angle upward from the right edge portion of the first joint portion 201b. That is, the first pushing-up portion 201c connects the first receiving portion 201a and the first joint portion 201b. And the first connecting member 201 is joined to the upper surface of the first outer ceiling panel 32A12 at the lower surface of the first joint portion 201b.

[0077] Also, a communication hole 201h that communicates in the vertical direction is formed in the first receiving portion 201a, similar to the substrate portion 101a according to the first embodiment. And the left inner wall of the communication hole 201h is located slightly to the right of the right tip of the first outer ceiling panel 32A12 for the first passage.

[0078] The first passage outer ceiling panel 32A12 and the partition unit SU are connected by the second connecting member 202. The second connecting member 202 extends in the longitudinal direction of the vehicle body as a whole. The longitudinal length of the second connecting member 202 in the vehicle body longitudinal direction is the same as the longitudinal length of the front left first partition panel 31A1 in the vehicle body longitudinal direction and the longitudinal length of the first passage ceiling panel 32A1 in the vehicle body longitudinal direction. Further, the cross-section of the second connecting member 202 perpendicular to the vehicle body longitudinal direction is generally in an L shape as a whole, and has a plate-like second receiving portion 202a parallel to the vertical direction and a plate-like second connecting portion 202b parallel to the vehicle body width direction.

[0079] The second connecting portion 202b is bent approximately at a right angle to the left at the upper end portion of the second receiving portion 202a. And the second connecting member 202 is joined to the lower surface of the first passage outer ceiling panel 32A12 on the upper surface of the second connecting portion 202b.

[0080] Note that the first joining portion 201b is joined on the right side of the center in the vehicle body width direction of the first passage outer ceiling panel 32A12. On the other hand, the second connecting portion 202b is joined approximately on the left side of the center in the vehicle body width direction of the first passage outer ceiling panel 32A12. And in the vertical direction, the first joining portion 201b and the second connecting portion 202b do not overlap.

[0081] The ceiling unit TU has a first passage inner ceiling panel 32A11 and a ceiling connecting member 67. The ceiling connecting member 67 extends in the longitudinal direction of the vehicle body as a whole. The longitudinal length of the ceiling connecting member 67 in the vehicle body longitudinal direction is the same as the longitudinal length of the first passage inner ceiling panel 32A11 in the vehicle body longitudinal direction. The ceiling connecting member 67 has a ceiling connecting portion 67a, a ceiling joining portion 67b, and a ceiling pushing-up portion 67c.

[0082] The ceiling connecting portion 67a and the ceiling joint portion 67b are parallel in the vehicle body width direction in a cross section orthogonal to the vehicle body longitudinal direction. The ceiling connecting portion 67a is located above the ceiling joint portion 67b. Also, the ceiling connecting portion 67a is located to the left of the ceiling joint portion 67b. Specifically, the position of the right edge portion of the ceiling connecting portion 67a in the vehicle body width direction is the same as the position of the left edge portion of the ceiling joint portion 67b in the vehicle body width direction. The ceiling pushing-up portion 67c is formed by bending downward at a substantially right angle from the right edge portion of the ceiling connecting portion 67a and upward at a substantially right angle from the left edge portion of the ceiling joint portion 67b. That is, the ceiling pushing-up portion 67c connects the ceiling connecting portion 67a and the ceiling joint portion 67b. And the ceiling connecting member 67 is joined to the upper surface of the inner ceiling panel 32A11 for the first passage at the lower surface of the ceiling joint portion 67b. Also, the left tip of the ceiling connecting portion 67a is located slightly to the left of the left tip of the inner ceiling panel 32A11 for the first passage.

[0083] Also, in the ceiling opening 32A1h of the ceiling panel 32A1 for the first passage, louvers 36 are installed over the entire length of the ceiling panel 32A1 for the first passage in the vehicle body longitudinal direction. The louvers 36 are in contact with the bottom surfaces of the left edge portion of the inner ceiling panel 32A11 for the first passage and the right edge portion of the outer ceiling panel 32A12 for the first passage, which are both edges of the ceiling opening 32A1h. Note that the louvers 36 are removably supported by hanging tools 69 that are fixed to the bottom surface of a portion where the communication hole 201h of the first receiving portion 201a is not formed and extend downward. A plurality of the hanging tools 69 are installed at predetermined intervals along the vehicle body longitudinal direction.

[0084] And the connecting unit RU is fastened by a bolt 54 inserted from below and the horizontal portion 40b of the ceiling frame 40 via a spacer 53 at a portion to the left of the first connecting member 201 of the outer ceiling panel 32A12 for the first passage. Note that a second connecting portion 202b of the second connecting member 202 is joined to the side opposite to the spacer 53 of the outer ceiling panel 32A12 for the first passage in the vertical direction, and the bolt 54 integrally fastens the second connecting portion 202b, the outer ceiling panel 32A12 for the first passage, the spacer 53, and the horizontal portion 40b from below.

[0085] The partition unit SU is fastened by a bolt 56 inserted from the right side to the second receiving portion 202a of the second connecting member 202 via a liner plate 55 at the second partition joint portion 51b. That is, the partition unit SU is detachably fixed to the ceiling joist 40 via the connecting unit RU. In a state where the partition unit SU is fixed to the ceiling joist 40, the front left first partition panel 31A1 is located below the right edge of the first passage outer ceiling panel 32A12, in other words, below the outer edge of the ceiling opening 32A1h.

[0086] The ceiling unit TU is fastened by a screw 68 inserted from below to the first receiving portion 201a of the first connecting member 201 at the ceiling connecting portion 67a. That is, the ceiling unit TU is detachably fixed to the ceiling joist 40 via the connecting unit RU. In a state where the ceiling unit TU is fixed to the ceiling joist 40, the left inner wall of the communication hole 201h of the first receiving portion 201a and the left tip of the ceiling connecting portion 67a are aligned in the vertical direction. Also, the screw 68 is fastened in the vicinity of the communication hole 201h of the first receiving portion 201a.

[0087] Also, the left tip of the first passage inner ceiling panel 32A11 is located on the right side of the front left first partition panel 31A1. On the other hand, the upper tip of the front left first partition panel 31A1 is located below the first passage inner ceiling panel 32A11. That is, a three-dimensional front left first gap AT11 is formed at the corner portion 30AC of the first passage 30A partitioned by the front left first partition panel 31A1 and the first passage inner ceiling panel 32A11. And the front left first gap AT11 communicates with the space S2 surrounded by the first receiving portion 201a, the ceiling connecting portion 67a, the first pushing-up portion 201c, and the ceiling pushing-up portion 67c.

[0088] Here, the bolt 56 is disposed between the front left first partition panel 31A1 and the first passage outer ceiling panel 32A12 in the vertical direction, and faces the front left first gap AT11 in the vehicle body width direction. Therefore, the bolt 56 can be easily attached to and detached from the front left first gap AT11. That is, the front left first partition panel 31A1 can be easily removed from the connection unit RU without removing the first passage inner ceiling panel 32A11.

[0089] On the other hand, the screw 68 faces the space S2 and the front left first gap AT11 in the vertical direction, but the space between the space S2 and the front left first gap AT11 is blocked by the louver 36. However, since the louver 36 can be removed, the screw 68 can be easily attached to and detached from the front left first gap AT11 and the space S2 by removing the louver 36. That is, the first passage inner ceiling panel 32A11 can be easily removed from the connection unit RU without removing the front left first partition panel 31A1.

[0090] Further, in a state where the connection unit RU is fixed to the ceiling frame 40, the communication hole 201h faces the opening 34h of the duct 34 in the vertical direction. Therefore, in the vertical direction, the inside of the duct 34 communicates with the first passage 30A through the opening 34h, the communication hole 201h, the space S2, the ceiling opening 32A1h, and the front left first gap AT11.

[0091] Moreover, in the second embodiment, a louver 36 is installed in the ceiling opening 32A1h. As a result, the internal structure above the ceiling panel 32A1 for the first passage is hidden, so the aesthetic appearance of the railway vehicle 1 is improved.

[0092] Also, in the second embodiment as well, similar to the case of the first embodiment, the left blocking member 63 and the right blocking member 64 are installed, and the left blocking member 63 and the right blocking member 64 shield the outside and inside of the vehicle in the vehicle body width direction of the communication hole 201h.

[0093] In the second embodiment, the ceiling unit TU and the connecting unit RU are fixed to the ceiling joist 40 in a state of being integrated by screws 68. In other words, the ceiling unit TU and the connecting unit RU are pre-assembled, and the pre-assembled integrated ceiling unit TU and connecting unit RU are fixed to the ceiling joist 40. In this case, although not shown, on the front right side first partition panel 31B1 side as well, by similarly fixing the integrated ceiling unit TU and connecting unit RU to the ceiling joist 40, the integrated ceiling unit TU and connecting unit RU will be supported by the roof structure via the ceiling joist 40.

[0094] Also, in the second embodiment, although the ceiling opening 32A1h is blocked by the louver 36, a decorative plate having air permeability may be fitted into the inner ceiling panel 32A11 for the first passage and the outer ceiling panel 32A12 for the first passage to block the ceiling opening 32A1h.

[0095] As described above, according to the railway vehicle 1 according to the first embodiment and the second embodiment, the front left first partition panel 31A1 facing the first passage 30A of the rear side access platform R2, the ceiling panel 32A1 for the first passage, and the inner ceiling panel 32A11 for the first passage (hereinafter, the ceiling panel 32A1 for the first passage, etc.) are provided. The upper end of the front left first partition panel 31A1 and the end on the front left first partition panel 31A1 side of the ceiling panel 32A1 for the first passage, etc. form the corner 30AC of the first passage 30A. It further includes a ceiling frame 40 supported by the roof structure and connecting means (connecting member 101, connecting unit RU) supported by the ceiling frame 40. The connecting means (connecting member 101, connecting unit RU) is arranged on the side opposite to the first passage 30A of the corner 30AC. The front left first partition panel 31A1 is detachably fixed to the connecting means (connecting member 101, connecting unit RU) by bolts 56, and the ceiling panel 32A1 for the first passage, etc. is detachably fixed to the connecting means (connecting member 101, connecting unit RU) by screws 62, 68. A front left first gap AT11 is formed at the corner 30AC, and the bolts 56 are arranged so as to be contactable from the front left first gap AT11, and the screws 62, 68 are arranged so as to be contactable from the front left first gap AT11. By the connecting means (connecting member 101, connecting unit RU), the front left first partition panel 31A1 is detachably fixed by bolts 56, and the ceiling panel 32A1 for the first passage, etc. is detachably fixed by screws 62, 68. The bolts 56 and the screws 62, 68 can be individually contacted through the front left first gap AT11 communicating with the first passage 30A. Therefore, it is possible to remove the ceiling panel 32A1 for the first passage, etc. without removing the front left first partition panel 31A1, and it is also possible to remove the front left first partition panel 31A1 without removing the ceiling panel 32A1 for the first passage, etc. Therefore, it becomes easy to remove both the front left first partition panel 31A1 and the ceiling panel 32A1 for the first passage, etc.

[0096] In addition, connection holes 101h and 201h are formed in the connection members 101 and 201, and the connection holes 101h and 201h communicate with a duct 34 disposed above a ceiling panel 32A1 for the first passage or the like and a front left first gap AT11. Therefore, the corner portion 30AC of the first passage 30A partitioned by the front left first partition panel 31A1 and the ceiling panel 32A1 for the first passage or the like is effectively utilized, and the space above the ceiling panel 32A1 for the first passage can be made compact.

[0097] Furthermore, in the first embodiment, since the corner portion 30AC is open, the number of parts can be reduced and the time required for the installation work around the corner portion 30AC can be shortened. On the other hand, in the second embodiment, since the ceiling opening 32A1h that forms a part of the corner portion 30AC is blocked by the louver 36, the aesthetic property is improved.

[0098] Note that this embodiment is merely an example and does not limit the present invention in any way. Therefore, the present invention can naturally be variously modified without departing from the gist thereof.
