Description

[Technical Field]

[0001] The present invention relates to a railway vehicle in which a door frame unit, in which a door and a frame body are integrated, is installed inside a platform facing an aisle, and to a method for manufacturing the railway vehicle. [Background technology]

[0002] Previously, when installing doors on a railroad car deck, the applicant directly secured the doors to a receiving member that was integrated with a frame member or the like that was joined to the body structure. Because the doors were equipped with multiple hinges, the fixing position of the doors had to be adjusted based on the position of the hinges when securing the doors to the receiving member. Furthermore, after installing the doors, the position of the door locks had to be adjusted. Because these adjustments were required on the opposite side of the door's passage, installing the doors on the railroad car deck took a long time. Furthermore, because the passageway on the deck was narrow, the time required for installing the doors interfered with other work.

[0003] Incidentally, a railway vehicle has been disclosed in which a door unit, in which the door and the frame are integrated, is installed on the body structure (see Patent Document 1). The door unit in Patent Document 1 is integrated outside the vehicle and then assembled into a through hole in the front body structure. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2022-69772 Summary of the Invention [Problem to be solved by the invention]

[0005] The door unit disclosed in Patent Document 1 is intended to be installed on the front body structure, and so it is not intended to be installed on the platform. Therefore, the relationship between the dimensions of the platform (deck) aisle and the door unit is unclear.

[0006] The present invention has been made to solve such problems, and aims to provide a railway vehicle and a method for manufacturing a railway vehicle that can shorten the time required to install doors facing an aisle inside a platform. [Means for solving the problem]

[0007] In order to achieve the above object, a railway vehicle according to one aspect of the present invention has the following features.

[0008] (1) A railway vehicle comprising a body structure having an opening formed therein and a partition panel that partitions an access platform passage that communicates with the opening, The partition panel includes a door unit that can be carried in through the opening, The door unit has a frame body and a door rotatably supported on the frame body via a hinge, The frame and the door are integrated and indirectly fixed to the body structure. According to the aspect described in (1) above, the frame and door that constitute the door unit are indirectly fixed to the body structure in an integrated state, so that the frame and door can be transported from the outside of the car body to the inside in an integrated state, thereby shortening the time required for the installation work of the door unit inside the car body.

[0009] (2) In the railway vehicle described in (1), the one end of the door may be formed outward from the end of the frame on the same side, and the rotation axis of the door may be formed between the one end of the door and the end of the frame on the same side. According to the aspect described in (2) above, the one end of the door is formed outward from the end of the frame on the same side, and the rotation axis is formed between the one end of the door and the end of the frame on the same side. As a result, for example, while the door is transitioning from a closed state to an open state, the end of the door near the rotation axis continues to cover the end of the frame on the same side. Therefore, it is possible to prevent a decrease in the aesthetic appeal of the interior space of the platform. (3) In the railway vehicle described in (1) or (2), the door units may include a first door unit and a second door unit, wherein the first door unit has a first frame body having a first opening, and a first door rotatably supported on the first frame body via a first hinge and capable of opening and closing the first opening, and the second door unit has a second frame body having a second opening, and a second door rotatably supported on the second frame body via a second hinge and capable of opening and closing the second opening, the first opening and the second opening are connected, and the first door unit in a state where the first frame body and the first door are integrated, and the second door unit in a state where the second frame body and the second door are integrated may be indirectly fixed to the body structure in an integrated state by being joined by the first frame body and the second frame body. According to the aspect described in (3) above, first, when the door unit is indirectly fixed to the body structure, the first frame body and the first door are integrated in the first door unit, and the second frame body and the second door are integrated in the second door unit. Therefore, the first door unit and the second door unit can be individually assembled outside the car body and then transported inside. Therefore, the time required for the door unit installation work inside the car body can be shortened. Furthermore, since the first door unit and the second door unit are indirectly fixed to the body structure in an integrated state by being joined with the first frame body and the second frame body, the first door unit and the second door unit, which are individually transported, can be integrated inside the car body and then fixed to the body structure. Therefore, the time required for the door unit installation work inside the car body can be shortened compared to when the first door unit and the second door unit are individually fixed to the body structure.

[0010] (4) A method for manufacturing a railway vehicle in which a door unit constituting a partition panel that divides an aisle of an access platform is indirectly fixed to a body structure, The door unit has a frame body and a door rotatably supported on the frame body via a hinge, an exterior assembly process of attaching the door to the frame via the hinge outside the vehicle body including the access platform to integrate the door and the frame, thereby assembling the door unit; a carrying-in process of carrying the door unit assembled in the exterior assembly process onto the loading / unloading platform; and a fixing step of indirectly fixing the door unit to the body structure via a predetermined member. According to the aspect described in (4) above, the door is attached to the frame body outside the car body including the access platform to integrate the door and the frame body, and after assembling the door unit, the door unit can be indirectly fixed to the body structure as it is, so that the time required for installing the door unit inside the car body can be shortened. [Effects of the Invention]

[0011] According to the present invention, the time required for installing a door facing the aisle inside the platform can be reduced. [Brief explanation of the drawings]

[0013] First Embodiment Next, a railway vehicle according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1A is a schematic side view of a railway vehicle (hereinafter referred to as "vehicle") according to the first embodiment of the present invention, and FIG. 1B is a view as viewed from the X arrow in FIG. 1A. For convenience, it is assumed that the vehicle 1 shown in FIG. 1A travels to the right, and the right side of the vehicle 1 traveling in the longitudinal direction (car body longitudinal direction) of a car body 10 constituting the vehicle 1 will be referred to as the "front side," and the left side opposite the traveling right side will be referred to as the "rear side." Furthermore, the right and left sides of the vehicle 1 when facing from the rear side in the car body longitudinal direction to the front side in the width direction (car body width direction) of the car body 10 will be referred to as the "right side" and "left side," respectively. Therefore, FIG. 1A is a schematic side view of the vehicle 1 as viewed from the right side, and FIG. 1B is a schematic front view of the vehicle 1 as viewed from the rear side.

[0014] The vehicle 1 will now be described. The vehicle 1 is an express vehicle. The vehicle 1 has a body structure 10A, which forms the framework of the vehicle body 10, and includes an underframe 11, a pair of front and rear end body structures 12, a pair of left and right side body structures 13, and a roof body structure 14. The schematic side view of the vehicle body 10 as viewed from the left side is symmetrical with respect to the longitudinal direction of the vehicle body with respect to the schematic side view shown in FIG. 1A. The schematic front view of the vehicle body 10 as viewed from the front side is the same as the schematic side view shown in FIG. 1B. However, the external shape of the vehicle body 10 can be set as appropriate. Therefore, the schematic side view of the vehicle body 10 as viewed from the left side and the schematic side view of the vehicle body 10 as viewed from the right side do not need to be symmetrical with respect to the longitudinal direction of the vehicle body. The schematic front view of the vehicle body 10 as viewed from the front side and the schematic front view of the vehicle body 10 as viewed from the rear side do not need to be the same.

[0015] The car body 10 is divided into a passenger compartment RI, a rear platform R2, and a front platform R3. The front platform R3, passenger compartment R1, and rear platform R2 are arranged in this order from the front along the longitudinal direction of the car body. The front platform R3 and passenger compartment R1 are separated by a front partition sidewall 20. The passenger compartment R1 and rear platform R2 are separated by a rear partition sidewall 21. The front partition sidewall 20 and the rear partition sidewall 21 are parallel to the width direction of the car 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.

[0016] A single entry / exit opening 13h is provided in the portion of each side structure 13 that constitutes the rear platform R2 and the portion that constitutes the front platform R3. The entry / exit opening 13h is formed in a vertically elongated rectangular shape. A entry / exit door 22 that can be opened and closed along the longitudinal direction of the car body is installed in the entry / exit opening 13h.

[0017] The end body structure 12 constituting the rear platform R2 and the end body structure 12 constituting the front platform R3 each have a single passage opening 12h. The passage opening 12h is formed in a vertically elongated rectangular shape. A passage door 23 that can be opened and closed along the width direction of the car body is installed in the passage opening 12h.

[0018] Fig. 2 is a schematic plan view showing the interior of the rear platform R2, Fig. 3A is a view taken along the line AA in Fig. 2, and Fig. 3B is a view taken along the line BB in Fig. 2.

[0019] The rear platform R2 has a passage 30 that is generally cross-shaped in plan view. Hereinafter, the portion of the passage 30 that is parallel to the longitudinal direction of the vehicle body will be referred to as the "first passage 30A," and the portion that is parallel to the width direction of the vehicle body will be referred to as the "second passage 30B." The first passage 30A is formed in a straight line in the center of the rear platform R2 in the width direction of the vehicle body. The second passage 30B is formed in a straight line near the front of the rear platform R2.

[0020] The planar shape of the passage 30 formed in the rear platform R2 is not limited to a substantially cross shape and may be changed as appropriate. For example, the planar shape of the passage 30 may be a substantially T-shape or a substantially L-shape. Furthermore, the planar shape of the passage 30 may be, for example, linear, curved, or wavy. When the planar shape of the passage 30 is substantially linear, the passage 30 may be formed on one side of the rear platform R2 in the vehicle width direction, or may be formed in the center of the rear platform R2 in the vehicle width direction.

[0021] The aisle 30 is defined by a floor panel 31, a partition panel 32, and a ceiling panel 33. The floor panel 31 is indirectly fixed to the underframe 11 (not shown in FIGS. 3A and 3B) located directly below. The ceiling panel 33 is indirectly fixed to the roof structure 14 (not shown in FIGS. 3A and 3B) located directly above. The partition panel 32 is disposed between the floor panel 31 and the ceiling panel 33, and is indirectly fixed to the underframe 11 and the roof structure 14, as will be described later. The interior surfaces of the floor panel 31 and the ceiling panel 33 are flat and perpendicular to the height direction of the car body, and the interior surface of the partition panel 32 is perpendicular to the interior surfaces of the floor panel 31 and the ceiling panel 33.

[0022] The partition panels 32 include a front-left partition panel 32A, a front-right partition panel 32B, a rear-left partition panel 32C, and a rear-right partition panel 32D. The front-left partition panel 32A is located in front of and to the left of the intersection of the first passage 30A and the second passage 30B. The front-right partition panel 32B is located in front of and to the right of the intersection of the first passage 30A and the second passage 30B. The rear-left partition panel 32C is located behind and to the left of the intersection of the first passage 30A and the second passage 30B. The rear-right partition panel 32D is located behind and to the right of the intersection of the first passage 30A and the second passage 30B.

[0023] The front left-hand partition panel 32A, the front right-hand partition panel 32B, the rear left-hand partition panel 32C, and the rear right-hand partition panel 32D 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] Hereinafter, the first straight portion, the second straight portion, and the corner portion of the front-left partition panel 32A will be referred to as the "front-left first straight portion 32A1," the "front-left second straight portion 32A2," and the "front-left corner portion 32A3," respectively. Similarly, the first straight portion, the second straight portion, and the corner portion of the front-right partition panel 32B will be referred to as the "front-right first straight portion 32B1," the "front-right second straight portion 32B2," and the "front-right corner portion 32B3," respectively. The first straight portion, the second straight portion, and the corner portion of the rear-left partition panel 32C will be referred to as the "rear-left first straight portion 32C1," the "rear-left second straight portion 32C2," and the "rear-left corner portion 32C3," respectively. The first straight portion, the second straight portion, and the corner portion of the rear-right partition panel 32D will be referred to as the "rear-right first straight portion 32D1," the "rear-right second straight portion 32D2," and the "rear-right corner portion 32D3," respectively.

[0025] Additionally, a first machine room R21 and a second machine room R22 are installed in this order from the rear side on the rear left partition panel 32C opposite the aisle 30 (on the vehicle exterior side). Similarly, a men's toilet room R23, a unisex toilet room R24, and a washbasin room R25 are installed in this order from the rear side on the rear right partition panel 32D opposite the aisle 30 (on the vehicle exterior side).

[0026] The cross section of the first passage 30A perpendicular to the vehicle body longitudinal direction (extension direction) is constant in the vehicle body longitudinal direction, and the cross section has a vertically elongated rectangular shape. That is, the width W1 and height H1 of the first passage 30A are constant in the vehicle body longitudinal direction. Furthermore, the cross section of the second passage 30B perpendicular to the vehicle body width direction (extension direction) is constant in the vehicle body width direction, and the cross section has a vertically elongated rectangular shape. That is, the width W2 and height H2 of the second passage 30B are constant in the vehicle body width direction.

[0027] In the first embodiment, the width W1 of the first passage 30A and the width W2 of the second passage 30B are the same, and the height H1 of the first passage 30A and the height H2 of the second passage 30B are the same. However, the relationship in size between the width W1 of the first passage 30A and the width W2 of the second passage 30B, and the relationship in size between the height H1 of the first passage 30A and the height H2 of the second passage 30B may be set as appropriate.

[0028] The first passage 30A is connected to the passage opening 12h. That is, when the passage door 23 is open, the first passage 30A and the passage opening 12h are in communication with each other. On the other hand, the second passage 30B is connected to the entry / exit openings 13h on both sides. That is, when the entry / exit doors 22 are open, the second passage 30B and the entry / exit openings 13h are in communication with each other. The width W3 and height H3 of the passage opening 12h are shorter than the width W1 and height H1 of the first passage 30A. Similarly, the width W4 and height H4 of the entry / exit opening 13h are shorter than the width W2 and height H2 of the second passage 30B.

[0029] In the first embodiment, the width W3 of the passage opening 12h is the same as the width W4 of the entry / exit opening 13h, and the height H3 of the passage opening 12h is the same as the height H4 of the entry / exit opening 13h. However, the relationship in size between the width W3 of the passage opening 12h and the width W4 of the entry / exit opening 13h, and the relationship in size between the height H3 of the passage opening 12h and the height H4 of the entry / exit opening 13h may be set as appropriate.

[0030] Next, the rear-left first straight portion 32C1 will be described. The rear-left first straight portion 32C1 includes the door unit TU. FIG. 4 is a view taken along the CC arrow in FIG. 2, including the door unit TU. FIG. 5A is a perspective view of the door unit TU as seen from the front side, and FIG. 5B is a perspective view of the door unit TU as seen from the rear side. Note that, hereinafter, the side of the door unit TU facing the aisle 30 when the door unit TU is installed on the rear access platform R2 will be referred to as the "front side" or "front side," and the side opposite the aisle 30 will be referred to as the "rear side" or "rear side." Furthermore, the left-right and up-down directions of the door unit TU are identified based on the "up," "down," "left," and "right" shown in FIGS. 5A and 5B. However, the relationship between these directions and the orientation of the door unit TU is not limited to the embodiment described below.

[0031] The door unit TU has a single-door unit TU1 and a double-door unit TU2. The shape of the door unit TU when viewed from the front is a substantially horizontally elongated rectangle, while the front shapes of the single-door unit TU1 and the double-door unit TU2 are substantially vertically elongated rectangles. The length of the long side of the single-door unit TU1 is the same as the length of the long side of the double-door unit TU2. The length of the short side of the double-door unit TU2 is approximately twice the length of the single-door unit TU1. In other words, approximately one-third of the left side of the door unit TU is made up of the single-door unit TU1, and approximately two-thirds of the right side of the door unit TU is made up of the double-door unit TU2.

[0032] The single-door unit TU1 and the double-door unit TU2 are adjacent to each other in the left-right direction, and the gap between the single-door unit TU1 and the double-door unit TU2 is closed by a hole closing member 41. The hole closing member 41 is made of an L-shaped steel material, and is adhered across the back surface of the single-door unit TU1 and the back surface of the double-door unit TU2, with its extension direction parallel to the long sides of the single-door unit TU1 and the double-door unit TU2. The upper and lower ends of the hole closing member 41 are aligned at the same height as the upper and lower ends of the single-door unit TU1 and the double-door unit TU2, respectively.

[0033] The double-door unit TU2 also has a double-door left-hand door unit TU21 and a double-door right-hand door unit TU22. The front view shapes of the double-door left-hand door unit TU21 and the double-door right-hand door unit TU22 are substantially vertically elongated rectangles. The long side length of the double-door left-hand door unit is the same as the long side length of the double-door right-hand door unit TU22. The short side length of the double-door left-hand door unit TU21 is substantially the same as the short side length of the double-door right-hand door unit TU22. In other words, approximately half of the left side of the double-door unit TU2 is made up of the double-door left-hand door unit TU21, and approximately half of the right side of the double-door unit TU2 is made up of the double-door right-hand door unit TU22.

[0034] The double-swing left door unit TU21 and the double-swing right door unit TU22 are integrated by an upper connecting member 42 and a lower connecting member 43. The upper connecting member 42 is joined across the back surface of a double-swing left upper frame 61U and a double-swing right upper frame 71U (described later), and is fixed to both upper frames 61U, 71U with bolts. The lower connecting member 43 is joined across the back surface of a double-swing left lower frame 61D and a double-swing right lower frame 71D (described later), and is fixed to both lower frames 61D, 71D with bolts.

[0035] When the door unit TU is installed as part of the rear left first straight portion 32C1, the first machine room R21 is located on the back side of the single door unit TU1, the second machine room R22 is located on the back side of the double door unit TU2, and a partition panel (not shown) that separates the second machine room R22 from the first machine room R21 is located on the back side of the boundary between the single door unit TU1 and the double door unit TU2. In other words, the single door unit TU1 forms the entrance to the first machine room R21, and the double door unit TU2 forms the entrance to the second machine room R22.

[0036] Figure 6A is an exploded oblique view of the single-door unit TU1, the double-door left-hand door unit TU21, and the double-door right-hand door unit TU22 as viewed from the front side of the door unit TU, and Figure 6B is an exploded oblique view of the single-door unit TU1, the double-door left-hand door unit TU21, and the double-door right-hand door unit TU22 as viewed from the back side of the door unit TU.

[0037] 6A and 6B, the single-swing door unit TU1 has a single-swing door 50 and a single-swing frame body 51, the left-hand double-swing door unit TU21 has a left-hand double-swing door 60 and a left-hand double-swing frame body 61, and the right-hand double-swing door unit TU22 has a right-hand double-swing door 70 and a right-hand double-swing frame body 71. In each of the door units TU1, TU21, TU22, the doors 50, 60, 70 are arranged on the front side of the frame bodies 51, 61, 71, respectively.

[0038] Next, the single-swing door unit TU1, the double-swing left-door unit TU21, and the double-swing right-door unit TU22 will be described individually. First, the single-swing door unit TU1 will be described. Fig. 7A is a perspective view of the single-swing frame body 51 as seen from the front side, Fig. 7B is a perspective view of the single-swing frame body 51 as seen from the back side, Fig. 8A is a perspective view of the single-swing door 50 as seen from the front side, and Fig. 8B is a perspective view of the single-swing door 50 as seen from the back side.

[0039] The single-swing frame body 51 has a generally square-shaped front view and includes an upper frame 51U, a lower frame 51D, a left-side vertical frame 51L, and a right-side vertical frame 51R. The left-side vertical frame 51L is connected perpendicularly to the left end of the upper frame 51U and the left end of the lower frame 51D. The right-side vertical frame 51R is connected perpendicularly to the right end of the upper frame 51U and the right end of the lower frame 51D. The upper frame 51U and the lower frame 51D are parallel, and the extension length of the upper frame 51U is the same as the extension length of the lower frame 51D. The left and right vertical frames 51L and 51R of the single-swing door are parallel to each other, and the length of the left and right vertical frames 51L and 51R in the extension direction is the same. The vertically elongated rectangular space surrounded by the upper frame 51U, the lower frame 51D, the left and right vertical frames 51L and 51R is referred to as the "single-swing opening TU1h."

[0040] A buffer member 511, against which the single-wing door 50 abuts when closed, is adhered to the front surface of the single-wing upper frame 51U. The buffer member 511 extends in the left-right direction. Similarly, a buffer member 513, against which the single-wing door 50 abuts when closed, is adhered to the front surface of the single-wing right vertical frame 51R. The buffer member 513 extends in the up-down direction. However, both or one of the buffer member 511 and the buffer member 513 may be adhered to the back surface of the single-wing door 50, against which it abuts when closed.

[0041] On the front of the left-side vertical frame 51L, five single-wing receiving bases 512, to which five single-wing hinges 503 (described later) are respectively joined, are arranged in a row at predetermined intervals in the vertical direction. Each single-wing receiving base 512 has four bolt insertion holes 512h arranged in a row at predetermined intervals in the vertical direction, through which bolts (not shown) are inserted to secure the single-wing hinges 503 to each other.

[0042] The back surface of the single-swing upper frame 51U is formed with an upper rod insertion hole 51Uh for single-swing doors, through which an upper rod 502Up for single-swing doors, described later, passes. Similarly, the back surface of the lower frame 51D is formed with a lower rod insertion hole 51Dh for single-swing doors, through which a lower rod 502Dp for single-swing doors, described later, passes. Furthermore, the back surface of the right vertical frame 51R is formed with a right rod insertion hole 51Rh for single-swing doors, through which a right rod 502Rp for single-swing doors, described later, passes.

[0043] The single-swing door 50 has a single-swing door body 501, a single-swing lock 502, and a single-swing hinge 503. The single-swing door body 501 is made up of a plate-like member having a substantially vertically elongated rectangular shape. The shape of the single-swing door body 501 when viewed from the front is the same as the shape of the entire single-swing door 50 when viewed from the front.

[0044] The single swing lock 502 is located at approximately the center in the vertical direction of the right edge of the single swing door body 501, and is exposed on the front and back sides of the single swing door body 501. A single swing keyhole (not shown) is formed on the front side of the single swing lock 502 for opening and closing the single swing lock 502 with a predetermined key (single swing key: not shown).

[0045] An upper rod for single swing 502Up, a lower rod for single swing 502Dp, and a right rod for single swing 502Rp for locking the single swing door 50 are provided on the back side of the single swing lock 502. The extending direction of the upper rod for single swing 502Up and the lower rod for single swing 502Dp is parallel to the long side direction of the single swing door main body 501. The extending direction of the right rod for single swing 502Rp is parallel to the short side direction of the single swing door main body 501.

[0046] The single swing upper rod 502Up, the single swing lower rod 502Dp, and the single swing right rod 502Rp slide integrally along the extending direction by a predetermined operation of the single swing key inserted into the single swing keyhole. In detail, when the single swing door 50 is in a locked state, the single swing upper rod 502Up is inserted into the single swing upper rod insertion hole 51Uh, the single swing lower rod 502Dp is inserted into the single swing lower rod insertion hole 51Dh, and the single swing right rod 502Rp is inserted into the single swing right rod insertion hole 51Rh. Then, by operating the single-swing key to release the lock from that state, the single-swing upper rod 502Up slides downward and comes out of the single-swing upper rod insertion hole 51Uh, the single-swing lower rod 502Dp slides upward and comes out of the single-swing lower rod insertion hole 51Dh, and the single-swing right rod 502Rp slides left and comes out of the single-swing right rod insertion hole 51Rh, making it possible to open the single-swing door 50.

[0047] The five single-leaf hinges 503 are arranged side by side at predetermined intervals in the vertical direction on the back surface of the left edge of the single-leaf door main body 501. Each single-leaf hinge 503 has four bolt insertion holes 503h arranged side by side at predetermined intervals in the vertical direction for fastening to the corresponding single-leaf receiving base 512 with bolts (not shown). Therefore, in the single-leaf door unit TU1, the single-leaf door 50 is rotatably supported on the single-leaf frame body 51 via the five single-leaf hinges 503. The rotation axis X1 of the single-leaf door 50 formed by the five single-leaf hinges 503 (single-leaf door rotation axis X1) is parallel to the vertical direction and is formed near the back surface of the left edge of the single-leaf door main body 501.

[0048] Furthermore, the length of the long side of the single-swing door body 501 is longer than the length of the long side of the single-swing opening TU1h, and the length of the short side of the single-swing door body 501 is longer than the length of the short side of the single-swing opening TU1h. When the single-swing door 50 is closed, it completely blocks the single-swing opening TU1h and abuts against the buffer members 511 and 513.

[0049] Next, the left-hand double door unit TU21 will be described. Fig. 9A is a perspective view of the left-hand double door frame 61 as seen from the front side, Fig. 9B is a perspective view of the left-hand double door frame 61 as seen from the back side, Fig. 10A is a perspective view of the left-hand double door 60 as seen from the front side, and Fig. 10B is a perspective view of the left-hand double door 60 as seen from the back side.

[0050] The left-hand frame 61 for double doors has a U-shape when viewed from the front. The left-hand frame 61 for double doors includes an upper left frame 61U, a lower left frame 61D, and a vertical left frame 61L for double doors. The vertical left frame 61L is connected perpendicularly to the left end of the upper left frame 61U and the left end of the lower left frame 61D. The upper left frame 61U and the lower left frame 61D for double doors are parallel, and the length of the upper left frame 61U in the extension direction is the same as the length of the lower left frame 61D in the extension direction. The vertically elongated rectangular space enclosed by the upper left frame 61U, the lower left frame 61D, and the vertical left frame 61L is referred to as the "left-hand opening TU21h."

[0051] A buffer member 611 is adhered to the front surface of the double-swinging left upper frame 61U, against which the double-swinging left door 60 abuts when closed. The buffer member 611 extends in the left-right direction. However, the buffer member 611 may also be adhered to the back surface of the double-swinging left door 60, against which it abuts when closed.

[0052] A two-door upper rod insertion hole 61Uh is formed on the back side of the two-door upper left frame 61U, through which an upper rod 602Up for two-door doors (described later) passes. Similarly, a two-door lower rod insertion hole 61Dh is formed on the back side of the two-door lower left frame 61D, through which a lower rod 602Dp for two-door doors (described later) passes.

[0053] Five left-hand double door support bases 612, which are respectively connected to five left-hand double door hinges 603 (described later), are arranged vertically at predetermined intervals on the front surface of the left-hand double door vertical frame 61L. Each left-hand double door support base 612 has four bolt insertion holes 612h arranged vertically at predetermined intervals, through which bolts (not shown) are inserted to secure the left-hand double door hinge 603 to each other.

[0054] The left-hand double door 60 has a left-hand double door body 601, a lock for double doors 602, and a left-hand double door hinge 603. The left-hand double door body 601 is made up of a vertically long rectangular plate-like member. The shape of the left-hand double door body 601 when viewed from the front is the same as the shape of the entire left-hand double door 60 when viewed from the front.

[0055] The double door lock 602 is disposed at approximately the center in the vertical direction of the right edge of the left double door body 601, and is exposed on the front and back sides of the left double door body 601. A double door keyhole (not shown) is formed on the front side of the double door lock 602 for opening and closing the double door lock 602 with a predetermined key (not shown).

[0056] An upper rod for double doors 602Up, a lower rod for double doors 602Dp, and a right rod for double doors 602Rp for locking the left-hand double doors 60 are provided on the back side of the double doors lock 602. The extending directions of the upper rod for double doors 602Up and the lower rod for double doors 602Dp are parallel to the long side direction of the left-hand double doors main body 601. The extending direction of the right rod for double doors 602Rp is parallel to the short side direction of the left-hand double doors main body 601.

[0057] The double-swing upper rod 602Up, the double-swing lower rod 602Dp, and the double-swing right rod 602Rp slide integrally along the extending direction by a predetermined operation of the double-swing key inserted into the double-swing keyhole. In detail, when the double-swing left door 60 is locked, the double-swing upper rod 602Up is inserted into the double-swing upper rod insertion hole 61Uh, the double-swing lower rod 602Dp is inserted into the double-swing lower rod insertion hole 61Dh, and the double-swing right rod 602Rp is inserted into the double-swing right rod insertion hole 702Bh, which will be described later. Then, by operating the double-door key to release the lock from that state, the double-door upper rod 602Up slides downward and comes out of the double-door upper rod insertion hole 61Uh, the double-door lower rod 602Dp slides upward and comes out of the double-door lower rod insertion hole 61Dh, and the double-door right rod 602Rp slides left and comes out of the double-door right rod insertion hole 702Bh, making it possible to open the left double-door door 60.

[0058] The five double-swing left-hand hinges 603 are arranged in a row at predetermined intervals in the vertical direction on the back surface of the left edge of the double-swing left-hand door main body 601. Each double-swing left-hand hinge 603 has four bolt insertion holes 603h arranged in a row at predetermined intervals in the vertical direction for fastening to the corresponding double-swing left-hand receiving base 612 with a bolt (not shown). Therefore, in the double-swing left-hand door unit TU21, the double-swing left-hand door 60 is rotatably supported on the double-swing left-hand frame body 61 via the five double-swing left-hand hinges 603. The rotation axis X21 (double-swing left-hand door rotation axis X21) of the double-swing left-hand door 60 formed by the five double-swing left-hand hinges 603 is parallel to the vertical direction and is formed near the back surface of the left edge of the double-swing left-hand door main body 601.

[0059] Furthermore, the length in the long side direction of the left double-door body 601 is longer than the length in the long side direction of the left double-door opening TU21h, and the length in the short side direction of the left double-door body 601 is longer than the length in the short side direction of the left double-door opening TU21h. When closed, the left double-door body 60 completely blocks the left double-door opening TU21h, and abuts against the buffer member 611 and a buffer member 702C, which will be described later.

[0060] Next, the double-swing right door unit TU22 will be described. Fig. 11A is a perspective view of the double-swing right frame body 71 as seen from the front side, Fig. 11B is a perspective view of the double-swing right frame body 71 as seen from the back side, Fig. 12A is a perspective view of the double-swing right door 70 as seen from the front side, and Fig. 12B is a perspective view of the double-swing right door 70 as seen from the back side.

[0061] The double-door right frame 71 has a U-shape when viewed from the front. The double-door right frame 71 includes an upper right frame 71U, a lower right frame 71D, and a vertical right frame 71R. The vertical right frame 71R is connected perpendicularly to the right end of the upper right frame 71U and the right end of the lower right frame 71D. The upper right frame 71U and the lower right frame 71D are parallel, and the length of the upper right frame 71U and the length of the lower right frame 71D are the same. The vertically elongated rectangular space enclosed by the upper right frame 71U, the lower right frame 71D, and the vertical right frame 71R is referred to as the "double-door right opening TU22h."

[0062] In the double-door unit TU2 in which the double-swing left door unit TU21 and the double-swing right door unit TU22 are integrated, the leading edge of the double-swing left upper frame 61U and the leading edge of the double-swing right upper frame 71U are closely spaced and face each other along the direction of extension, and the leading edge of the double-swing left lower frame 61D and the leading edge of the double-swing right lower frame 71D are closely spaced and face each other along the direction of extension. The double-swing left opening TU21h and the double-swing right opening TU22h are connected to form an integrated "double-swing opening TU2h."

[0063] A buffer member 711 is adhered to the front surface of the double-swing right upper frame 71U, against which the double-swing right door 70 abuts when it is closed. The buffer member 711 extends in the left-right direction. However, the buffer member 711 may also be adhered to the back surface of the double-swing right door 70, against which it abuts when closed.

[0064] Five double-door right-side receiving bases 712, which are respectively connected to five double-door right-side hinges 703 (described later), are arranged vertically at predetermined intervals on the front surface of the double-door right-side vertical frame 71R. Each double-door right-side receiving base 712 has four bolt insertion holes 712h arranged vertically at predetermined intervals, through which bolts (not shown) are inserted to secure the double-door right-side hinge 703 to each other.

[0065] The right-side double-swing door 70 has a right-side double-swing door main body 701, a rod receiving member for double-swing 702, and a right-side double-swing hinge 703. The right-side double-swing door main body 701 is composed of a vertically long rectangular plate-like member. The rod receiving member for double-swing 702 is installed on the back surface of the left edge of the right-side double-swing door main body 701, and has a rod receiving main body for double-swing 702A, a rod receiving member for double-swing 702B, and a buffer member 702C.

[0066] The rod receiving main body portion 702A for double doors is provided over the entire vertical length of the right-side double doors body 701. The rod receiving main body portion 702A for double doors is made of L-shaped steel, and the tip of the shorter straight portion in a cross section perpendicular to the extension direction of the rod receiving main body portion 702A for double doors is adhered to the left end back surface of the right-side double doors body 701, and the longer straight portion extends to the left. In other words, the rod receiving main body portion 702A for double doors protrudes leftward from the left end of the right-side double doors body 701 by a constant width.

[0067] The rod receiving portion 702B for double doors is made of L-shaped steel, and the extension direction of the rod receiving portion 702B for double doors is parallel to the up-down direction. One straight portion of the cross section perpendicular to the extension direction of the rod receiving portion 702B for double doors is bonded to the back surface of the longer straight portion of the rod receiving main body portion 702A for double doors, and the other straight portion of the cross section perpendicular to the extension direction of the rod receiving portion 702B for double doors protrudes toward the back surface while intersecting perpendicular to the back surface of the longer straight portion of the rod receiving main body portion 702A for double doors. A right-side rod insertion hole 702Bh for double doors, through which the right rod 602Rp for double doors is inserted, is formed in the other straight portion.

[0068] The left double-swing door unit TU21 includes a double-swing lock 602, and the right double-swing door unit TU22 includes a double-swing rod receiving portion 702B through which the right double-swing rod 602Rp is inserted. Therefore, in order to completely open the double-swing opening TU2h, it is necessary to open the left double-swing door unit TU21 and then open the right double-swing door unit TU22. Conversely, in order to completely close the double-swing opening TU2h, it is necessary to close the right double-swing door unit TU22 and then close the left double-swing door unit TU21.

[0069] When the double-swing left-hand door unit TU21 and the double-swing right-hand door unit TU22 are closed, the right end of the double-swing left-hand door 60 and the left end of the double-swing right-hand door 70 are close to each other in the direction of their short sides. Therefore, when the double-swing left-hand door unit TU21 and the double-swing right-hand door unit TU22 are closed, the double-swing rod receiving main body 702A is disposed on the back side of the right edge of the double-swing left-hand door 60. A buffer member 702C for the double-swing left-hand door 60 to abut against is adhered to the front surface of the double-swing rod receiving main body 702A. The buffer member 702C extends in the vertical direction.

[0070] The five double-swing right-side hinges 703 are arranged in a row at predetermined intervals in the vertical direction on the back surface of the right edge of the double-swing right-side door main body 701. Each double-swing right-side hinge 703 has four bolt insertion holes 703h arranged in a row at predetermined intervals in the vertical direction for fastening to the corresponding double-swing right-side receiving base 712 with a bolt (not shown). Therefore, in the double-swing right-side door unit TU22, the double-swing right-side door 70 is rotatably supported on the double-swing right-side frame body 71 via the five double-swing right-side hinges 703. The rotation axis X22 of the double-swing right-side door 70 formed by the five double-swing right-side hinges 703 (double-swing right-side door rotation axis X22) is parallel to the vertical direction and is formed near the back surface of the right edge of the double-swing right-side door main body 701.

[0071] The long side length of the double right door 70 is longer than the long side length of the double right opening TU22h, and the short side length of the double right door 70 is longer than the short side length of the double right opening TU22h. When closed, the double right door 70 completely blocks the double right opening TU22h and abuts against the buffer member 711.

[0072] Next, a description will be given of the positional relationship between the door rotation axes X1, X21, X22, the door main bodies 501, 601, 701, and the frames 51, 61, 71 when the door units TU1, TU21, TU22 are closed. Figure 13 is a view seen from the arrow DD in Figure 4.

[0073] The single-door rotation axis X1 is formed slightly away from the left end 50s of the single-door 50, which is also the left end of the single-door main body 501, towards the center (inside) in the short-side direction. On the other hand, the single-door rotation axis X1 is formed at approximately the same position as the left end 51s of the single-door frame body 51 in the short-side direction. In other words, in the single-door unit TU1, the left end 50s of the single-door 50 is formed further to the left than the left end 51s of the single-door frame body 51 in the left-right direction, and the single-door 50 is formed significantly further left than the single-door frame body 51.

[0074] The double-swing left-hand door rotation axis X21 is formed slightly toward the center (inner) in the short-side direction from the left end 60s of the double-swing left-hand door 60, which is also the left end of the double-swing left-hand door main body 601. On the other hand, the double-swing left-hand door rotation axis X21 is formed in approximately the same position in the short-side direction as the left end 61s of the double-swing left-hand frame 61. In other words, in the double-swing left-hand door unit TU21, the left end 60s of the double-swing left-hand door 60 is located to the left of the left end 61s of the double-swing left-hand frame 61 in the left-right direction, and the double-swing left-hand door 60 is formed farther to the left than the double-swing left-hand frame 61.

[0075] The double-swing right-door rotation axis X22 is formed slightly toward the center (inner) in the short-side direction from the right end 70s of the double-swing right-door 70, which is also the right end of the double-swing right-door main body 701. On the other hand, the double-swing right-door rotation axis X22 is formed in approximately the same position in the short-side direction as the right end 71s of the double-swing right-door frame body 71. In other words, in the double-swing right-door unit TU22, the right end 70s of the double-swing right-door 70 is located to the right of the right end 71s of the double-swing right-door frame body 71 in the left-right direction, and the double-swing right-door 70 is formed farther to the right than the double-swing right-door frame body 71.

[0076] Next, the installation status of the door unit TU will be explained. The door unit TU is indirectly fixed to the underframe 11 and the roof structure 14. Fig. 14 is a view seen from the arrow EE in Fig. 4. As shown in Fig. 14, for example, the single-swing lower frame 51D of the single-swing door unit TU1 is fixed with screws 26 to a lower support member 25 fixed to the floor panel 31, and the single-swing upper frame 51U is fixed with screws 28 to an upper support member 27 fixed to the ceiling panel 33. The floor panel 31 is fixed to floor supports 111 that make up the underframe 11 (not shown in Fig. 14), and the ceiling panel 33 is fixed to ceiling ribs 141 that are fixed to rafters (not shown) that make up the roof structure 14 (not shown in Fig. 14).

[0077] Although not shown, for the double-swinging left door unit TU21, similarly to the single-swinging door unit TU1, the double-swinging left lower frame 61D is fixed with screws 26 to a lower receiving member 25 fixed to the floor panel 31, and the double-swinging left upper frame 61U is fixed with screws 28 to an upper receiving member 27 fixed to the ceiling panel 33. Similarly, for the double-swinging right door unit TU22, the double-swinging right lower frame 71D is fixed with screws 26 to a lower receiving member 25 fixed to the floor panel 31, and the double-swinging right upper frame 71U is fixed with screws 28 to an upper receiving member 27 fixed to the ceiling panel 33.

[0078] Next, the external dimensions of the single-door unit TU1, the left-side double-door unit TU21, and the right-side double-door unit TU22 will be described. Figure 15 is a schematic front view of each of the door units TU1, TU21, TU22 in the closed state.

[0079] In the single-door unit TU1, the upper end of the single-door frame 51 slightly protrudes upward from the upper end of the single-door 50. Furthermore, the left edge of the single-door 50 slightly protrudes leftward from the left end of the single-door frame 51. In the short-side direction of the single-door unit TU1, the right end of the single-door 50 and the right end of the single-door frame 51 are aligned at approximately the same position, and in the long-side direction of the single-door unit TU1, the bottom end of the single-door 50 and the bottom end of the single-door frame 51 are aligned at approximately the same position. Therefore, the short-side length L11 of the single-door unit TU1 is the same as the short-side length of the single-door 50, and the long-side length L12 of the single-door unit TU1 is the same as the long-side length of the single-door frame 51. The short-side length of the single-door 50 is essentially the short-side length of the single-door main body 501.

[0080] In the double-swinging left-hand door unit TU21, the upper end of the double-swinging left-hand frame body 61 protrudes slightly upward from the upper end of the double-swinging left-hand door 60. Also, the left edge of the double-swinging left-hand door 60 protrudes slightly leftward from the left end of the double-swinging left-hand frame body 61. In the short-side direction of the double-swinging left-hand door unit TU21, the right end of the double-swinging left-hand door 60 and the right end of the double-swinging left-hand frame body 61 are aligned at approximately the same position, and in the long-side direction of the double-swinging left-hand door unit TU21, the bottom end of the double-swinging left-hand door 60 and the bottom end of the double-swinging left-hand frame body 61 are aligned at approximately the same position. Therefore, the short-side length L211 of the double-swinging left-hand door unit TU21 is the same as the short-side length of the double-swinging left-hand door 60, and the long-side length L212 of the double-swinging left-hand door unit TU21 is the same as the long-side length of the double-swinging left-hand frame body 61. The length of the short side of the left double door 60 is essentially the length of the short side of the left double door body 601.

[0081] In the double-swinging right-side door unit TU22, the upper end of the double-swinging right-side frame body 71 protrudes slightly upward from the upper end of the double-swinging right-side door 70. Furthermore, the right edge of the double-swinging right-side door 70 protrudes slightly to the right from the right end of the double-swinging right-side frame body 71, and the left edge of the double-swinging right-side door 70 protrudes slightly to the left from the left end of the double-swinging right-side frame body 71. Furthermore, in the long-side direction of the double-swinging right-side door unit TU22, the bottom end of the double-swinging right-side door 70 and the bottom end of the double-swinging right-side frame body 71 are aligned at approximately the same position. Therefore, the short-side length L221 of the double-swinging right-side door unit TU22 is the same as the short-side length of the double-swinging right-side door 70, and the long-side length L222 of the double-swinging right-side door unit TU22 is the same as the long-side length of the double-swinging right-side frame body 71. In addition, the length of the short side of the double-swing right-side door 70 is longer than the length of the short side of the double-swing right-side door body 701 because the double-swing rod receiving body part 702A protrudes leftward from the left end of the double-swing right-side door body 701.

[0082] When the door unit TU is installed on the rear platform R2, it is formed from near the interior surface of the floor panel 31 to near the interior surface of the ceiling panel 33 (see FIG. 4). At least the long-side length L12 of the single-swing door unit TU1, the long-side length L212 of the double-swing left door unit TU21, and the long-side length L222 of the double-swing right door unit TU22 are shorter than the height H1 of the first passage 30A and the height H2 of the second passage 30B, and longer than the height H3 of the passage opening 12h and the height H4 of the entry / exit opening 13h. In addition, the short-side length L11 of the single-swing door unit TU1, the short-side length L211 of the double-swing left door unit TU21, and the short-side length L221 of the double-swing right door unit TU22 are shorter than the height H3 of the passage opening 12h and the height H4 of the entry / exit opening 13h.

[0083] Next, a method for installing the door unit TU will be described. Fig. 16 is a flowchart of a method for manufacturing the vehicle 1, including a method for installing the door unit TU inside the rear platform R2. The method for installing the door unit TU inside the rear platform R2 includes an exterior assembly process S1, an exterior disassembly process S2, a carry-in process S3, an interior integration process S4, and an interior fixing process S5.

[0084] In the exterior assembly process S1, the single-swing door unit TU1 and the double-swing door unit TU2 are individually assembled outside the rear access platform R2. For example, first, for each door unit TU1, TU21, TU22, the positions of the bolt insertion holes 503h, 603h, 703h of each hinge 503, 603, 703 are aligned with the positions of the bolt insertion holes 512h, 612h, 712h of each receiving base 512, 612, 712, and bolts (not shown) are inserted therethrough to fasten the doors 50, 60, 70 and the frames 51, 61, 71 to be integrated. Here, particularly for the single-swing door unit TU1, it is necessary to adjust the positions of the single-swing rods 502Rp, 502Up, 502Dp and the single-swing rod insertion holes 51Rh, 51Uh, 51Dh. Similarly, for the left double-swing door unit TU21, it is necessary to adjust the positions of the double-swing rods 602Up, 602Dp and the double-swing rod insertion holes 61Uh, 61Dh. Next, the double-swing door unit TU2 is assembled. That is, the left double-swing door unit TU21 and the right double-swing door unit TU22 are integrated with the upper connecting member 42 and the lower connecting member 43. At this time, it is necessary to adjust the position of the right double-swing rod 602Rp and the right double-swing rod insertion hole 702Bh.

[0085] In the outside-of-vehicle disassembly step S2, the double-door unit TU2 is disassembled into a left-side double-door unit TU21 and a right-side double-door unit TU22. The outside-of-vehicle disassembly step S2 is performed immediately before the carry-in step S3.

[0086] In the carry-in process S3, the door units TU1, TU21, TU22 are carried into the interior of the rear access platform R2 through the passage opening 12h or the getting-in opening 13h. As mentioned above, the long-side length L12 of the single-swing door unit TU1, the long-side length L212 of the double-swing left-side door unit TU21, and the long-side length L222 of the double-swing right-side door unit TU22 are longer than the height H3 of the passage opening 12h or the height H4 of the getting-in opening 13h, and the short-side length L11 of the single-swing door unit TU1, the short-side length L211 of the double-swing left-side door unit TU21, and the short-side length L221 of the double-swing right-side door unit TU22 are shorter than the height H3 of the passage opening 12h or the height H4 of the getting-in opening 13h. Therefore, in the delivery process S3, the single-door unit TU1, the left-side double-door unit TU21, and the right-side double-door unit TU22 are basically delivered in a state where the short sides of the single-door unit TU1, the left-side double-door unit TU21, and the right-side double-door unit TU22 are parallel to the vehicle height direction.

[0087] In the vehicle interior integration step S4, the left double door unit TU21 and the right double door unit TU22 are integrated with the upper connecting member 42 and the lower connecting member 43 to assemble the double door unit TU2.

[0088] Note that the single-swing door unit TU1, the double-swing left-door unit TU21, and the double-swing right-door unit TU22 are carried in with their respective short sides parallel to the vehicle body height direction. Therefore, in the interior integration step S4, the door units TU1, TU21, and TU22 may be brought into a position where their respective long sides are parallel to the vehicle body height direction. In this case, for example, the door units TU1, TU21, and TU22 may be rotated so that the lower end corners on which the door rotation axes X1, X21, and X22 are formed are raised around rotation fulcrums O1, O21, and O22 (see FIG. 15 ). When performing the interior integration step S4 in this manner, it is preferable to ensure that the outer edges of the door units TU1, TU21, and TU22, when connected to the farthest points from the rotation fulcrums O1, O21, and O22, do not come into contact with the ceiling panel 33 when the line connecting the outer edges of the door units TU1, TU21, and TU22 to the farthest points is perpendicular to the interior surface of the floor panel 31, in order to perform the work smoothly, in other words, to prevent the work from taking too long. For this purpose, it is preferable that the lengths L113, L213, and L223 of the straight lines are shorter than the height H1 of the first passage 30A (see FIG. 15).

[0089] In the vehicle interior fixing step S5, the door unit TU is fixed, for example, with screws 26 to a lower receiving member 25 fixed to a floor panel 31, and is also fixed with screws 28 to an upper receiving member 27 fixed to a ceiling panel 33.

[0090] As described above, the vehicle 1 comprises a body structure 10A in which openings 12h and 13h are formed, and a partition panel 32 that partitions the passage 30 of the rear access platform R2 that communicates with the openings, and the partition panel 32 includes door units TU1, TU21, and TU22 that can be carried in through the openings 12h and 13h, and the door units TU1, TU21, and TU22 have frame bodies 51, 61, and 71 and doors 50, 60, and 70 that are rotatably supported on the frame bodies 51, 61, and 71 via hinges 503, 603, and 70, and are indirectly fixed to the underframe 11 of the body structure 10A and the roof body structure 14 (body structure) in a state in which the frame bodies 51, 61, and 71 and the doors 50, 60, and 70 are integrated. The frame bodies 51, 61, 71 and the doors 50, 60, 70 that constitute the door units TU1, TU21, TU22 are indirectly fixed to the underframe 11 and the roof structure 14 (structure) in an integrated state, so it is possible to adjust in advance the attachment positions of the doors 50, 60, 70 relative to the frame bodies 51, 61, 71 outside the vehicle 1 and then transport the frame bodies 51, 61, 71 and the doors 50, 60, 70 integrated into the rear access platform R2 from the outside to the inside. Therefore, it is possible to shorten the time required to install the door units TU1, TU21, TU22 inside the rear access platform R2.

[0091] Furthermore, according to vehicle 1, when doors 50, 60, 70 are closed, one end of doors 50, 60, 70 (the left end for doors 50, 60, and the right end for door 70) is formed outside the end of the same side of frame bodies 51, 61, 71, and rotation axes X1, X21, X22 are formed between the one end of doors 50, 60, 70 and the end of the same side of frame bodies 51, 61, 71. One end of the doors 50, 60, 70 is formed outward from the end on the same side of the frame bodies 51, 61, 71, and the rotation axes X1, X21, X22 are formed between the one end of the doors 50, 60, 70 and the end on the same side of the frame bodies 51, 61, 71. As a result, for example, while the doors 50, 60, 70 are shifting from the closed state to the open state, the end of the doors 50, 60, 70 near the rotation axes X1, X21, X22 continues to cover the end on the same side of the frame bodies 51, 61, 71. This prevents a decrease in the aesthetic sense of the interior space of the rear access platform R2.

[0092] Furthermore, according to the vehicle 1, the door units TU include a double-swing left door unit TU21 (first door unit) and a double-swing right door unit TU22 (second door unit), and the double-swing left door unit TU21 includes a double-swing left frame body 61 (first frame body) having a double-swing left opening TU21h (first opening), and a double-swing left door 60 (first door) that is rotatably supported on the double-swing left frame body 61 via a double-swing left hinge 603 (first hinge) and can open and close the double-swing left opening TU21h, and the double-swing right door unit TU22 includes a double-swing right frame body 71 (second frame body) having a double-swing right opening TU22h (second opening), The double-swing right door 70 (second door) is rotatably supported on the double-swing right frame body 71 via a double-swing right hinge 703 (second hinge) and can open and close the double-swing right opening TU22h, the double-swing left opening TU21h and the double-swing right opening TU22h are connected, and the double-swing left door unit TU21, in which the double-swing left frame body 61 and the double-swing left door 60 are integrated, and the double-swing right door unit TU22, in which the double-swing right frame body 71 and the double-swing right door 70 are integrated, are joined together by the double-swing left frame body 61 and the double-swing right frame body 71 and are indirectly fixed to the underframe 11 and the roof structure 14 (structure). Therefore, first, when the door units TU21, TU22 are indirectly fixed to the underframe 11 and the roof body structure 14 (body structure), the double-swing left-hand door unit TU21 is in a state in which the double-swing left-hand frame body 61 and the double-swing left-hand door 60 are integrated together, and the double-swing right-hand frame body 71 and the double-swing right-hand door 70 are integrated together in the double-swing left-hand door unit TU21, so the double-swing left-hand door unit TU21 and the double-swing right-hand door unit TU22 can be assembled separately outside the rear access platform R2 and then carried inside. Therefore, the time required for the installation work of the double-swing left-hand door unit TU21 and the double-swing right-hand door unit TU22 inside the rear access platform R2 can be shortened.Furthermore, since the double-swing left-hand door unit TU21 and the double-swing right-hand door unit TU22 are joined together with the double-swing left-hand frame body 61 and the double-swing right-hand frame body 71 and indirectly fixed to the underframe 11 and the roof body structure 14 (body structure), the double-swing left-hand door unit TU21 and the double-swing right-hand door unit TU22, which have been carried in separately, can be integrated inside the vehicle and then indirectly fixed to the underframe 11 and the roof body structure 14 (body structure). Therefore, the time required for the installation work of the double-swing left-hand door unit TU21 and the double-swing right-hand door unit TU22 inside the rear access platform R2 can be shortened compared to when the double-swing left-hand door unit TU21 and the double-swing right-hand door unit TU22 are fixed individually to the underframe 11 and the roof body structure 14 (body structure).

[0093] In addition, the manufacturing method of the vehicle 1 according to the first embodiment includes an exterior assembly process in which the doors 50, 60, 70 are attached to the frame bodies 51, 61, 71 via hinges 503, 603, 703 outside the vehicle body 10 including the rear access platform R2 to integrate the doors 50, 60, 70 with the frame bodies 51, 61, 71, and individually assemble the door units TU1, TU21, TU22; a transport process in which the door units TU1, TU21, TU22 assembled by the exterior assembly process are transported into the rear access platform R2; and a fixing process indirectly fixing the door units TU1, TU21, TU22 to the underframe 11 and the roof structure 14 (structure) via a lower support member 25 and an upper support member 27 (predetermined members). Outside the vehicle body 10 including the rear access platform R2, the doors 50, 60, 70 are attached to the frame bodies 51, 61, 71 to integrate the doors 50, 60, 70 with the frame bodies 51, 61, 71, and after assembling the door units TU1, TU21, TU22, the door units TU1, TU21, TU22 can be indirectly fixed to the frame 11 and the roof structure 14 (structure), thereby shortening the time required to install the door units TU1, TU21, TU22 inside the rear access platform R2.

[0094] <Example of change> Next, a modified example of the vehicle 1 according to the first embodiment will be described. The first embodiment described above can be modified as appropriate without departing from the spirit of the present invention. The door unit TU has a single-door unit TU1 and a double-door unit TU2, but may be configured with only one of them. For example, if the door unit TU is configured with a single-door unit TU1, the vehicle exterior disassembly step S2 and vehicle interior integration step S4 will not be performed in the door unit TU installation method.

[0095] The door unit TU forms the rear left first straight portion 32C1 that defines the first passage 30A, but may also form the rear left second straight portion 32C2 or the rear left corner portion 32C3 that defines the second passage 30B. Alternatively, the door unit TU1 may form the front left partition panel 32A, the front right partition panel 32B, or the rear right partition panel 32D.

[0096] The partition panel 32 including the door unit TU is fixed to the ceiling ribs via the ceiling panel 33, but it may also be fixed to the ceiling ribs without the ceiling panel 33. In this case, the ceiling panel 33 will ultimately be positioned lower than the upper end of the partition panel 32, but the ceiling panel 33 may be fixed to the partition panel 32 after the partition panel 32 is fixed to the ceiling ribs.

[0097] In a front view, the right ends of the single-swing door body 501 and the left-hand double-swing door body 601 are in approximately the same position (aligned) as the right ends of the single-swing frame body 51 and the left-hand double-swing frame body 61, but may be to the right or left of the right ends of the single-swing frame body 51 and the left-hand double-swing frame body 61. Similarly, in a front view, the left end of the right-hand double-swing door body 701 is in approximately the same position (aligned) as the left end of the right-hand double-swing frame body 71, but may be to the left or right of the left end of the right-hand double-swing frame body 71.

[0098] The single-door lock 502 has three rods 502Up, 502Dp, and 502Rp, but the number of rods may be changed as appropriate. For example, the single-door lock 502 may have only the single-door right rod 502Rp. The same applies to the number of rods for the double-door lock 602.

[0099] The door unit TU forms the entrances to the first machine room R21 and the second machine room R22, but the location where the door unit TU forms the entrances is not particularly limited and may be changed as appropriate. For example, the door unit TU may form the entrance to the unisex toilet room R24 or the entrance to a multipurpose room.

[0100] It should be noted that the present embodiment is merely an example and does not limit the present invention in any way. Naturally, the present invention can be modified in various ways without departing from the spirit and scope of the present invention. [Explanation of symbols]
