Description

[Technical Field]

[0001] The present invention relates to a railway vehicle having a side post member disposed near a window frame. [Background technology]

[0002] A railway vehicle is disclosed which has hat-shaped cross-section members 3, 3a, 3b, 3L which have outer flange portions 31, 31a, 31b, 31L joined to the inside surface of the side panel 2 and extend in the rail direction, and hat-shaped cross-section side pillar members 4 which have outer flange portions 41 joined to the inside zenith portions 32, 32a, 32b of the cross-section members 3, 3a, 3b, 3L and extend in the vertical direction of the vehicle (see Patent Document 1).

[0003] The side pillar member 4 described in Patent Document 1 is formed with a notch corresponding to the curved portion 223 of the wainscot 22. The area of ​​the side pillar member 4 where no notch is formed is formed linearly with the same cross-sectional shape in the vertical direction of the vehicle.

[0004] [Patent Document 1] Patent No. 7336580 Summary of the Invention [Problem to be solved by the invention]

[0005] The height (length in the direction of the sleepers) of the cross frame member 3 described in Patent Document 1 is the same regardless of the installation location, but it is possible that the height (length in the direction of the sleepers) of the cross frame member may differ depending on the installation location (for example, when the height of the cross frame member in the headboard section is made lower than the height of the cross frame member in the waistboard section in order to provide a side door opening and closing mechanism), in which case it becomes difficult to abut and weld the side pillar members to the inside-side ceiling portions of all the cross frame members as in Patent Document 1.

[0006] The present invention has been made to solve such problems, and has an object to provide a railway vehicle having side post members that are highly usable. [Means for solving the problem]

[0007] A railway vehicle according to one aspect of the present invention comprises: (1) A railway vehicle including a side post member arranged near a window frame, the side post member being made of a single plate-like member and having a base plate portion, a first flange portion, and a second flange portion formed along the longitudinal direction of the side post member, in a cross section perpendicular to the longitudinal direction of the side post member, the base plate portion, the first flange portion, and the second flange portion are parallel to the longitudinal direction of the car body, the base plate portion is approximately perpendicular to the floor surface over the entire length of the side post member, the first flange portion and the second flange portion are arranged on the car outer side in the car body width direction than the base plate portion, the first flange portion is formed in a first range in the longitudinal direction of the side post member, and the second flange portion is formed in a second range in the longitudinal direction of the side post member, and the distance from the base plate portion to the first flange portion in the car body width direction is different from the distance from the base plate portion to the second flange portion in the car body width direction. In the above-described railway vehicle, the distance from the first flange portion formed in the first region to the base plate portion in the carbody width direction is different from the distance from the second flange portion formed in the second region to the base plate portion, which increases the degree of freedom for the internal structure on the car exterior side relative to the side pillar members, thereby improving the usability of the side pillar members.

[0008] (2) The railway vehicle described in (1), further comprising side outer panels and cross beam members joined to the side outer panels on the outboard sides of the side post members in the carbody width direction, the cross beam members including a first cross beam member having a first length in the carbody width direction and a second cross beam member having a second length in the carbody width direction, the first cross beam member being arranged in a range corresponding to the first range in the longitudinal direction of the side post members, the second cross beam member being arranged in a range corresponding to the second range in the longitudinal direction of the side post members, the first flange portion being joined to an inboard surface of the first cross beam member, and the second flange portion being joined to an inboard surface of the second cross beam member. Since the first flange portion is bonded to the first cross beam member and the second flange portion is bonded to the second cross beam member in correspondence with the first and second cross beam members having different lengths in the carbody width direction, the usability of the side post members is improved and the joining work of the side post members and the cross beam members is facilitated.

[0009] (3) A railway vehicle as described in (1) or (2), wherein the side pillar members further have third flange portions, and in a cross section perpendicular to the longitudinal direction of the side pillar members, the third flange portions are parallel to the longitudinal direction of the carbody, the third flange portions are disposed on the outer side of the car and on the window frame side of the base plate portions, and the distance from the base plate portion to the third flange portions is longer than the distance from the base plate portion to the first flange portions and the distance from the base plate portion to the second flange portions. In addition to the first flange portions and the second flange portions, a third flange portion is also provided, the distance to which is longer than both of the first flange portions and the second flange portions in the carbody width direction. This further increases the degree of freedom in the internal structure of the outer side of the car than the side pillar members. [Effects of the Invention]

[0010] According to the present invention, the usability of the side pillar member can be improved. [Brief explanation of the drawings]

[0012] Next, a railway vehicle system and railway vehicles according to one aspect of an embodiment of the present invention will be described in detail with reference to the drawings. Figures 1A and 1B are schematic side views of a first railway vehicle (hereinafter referred to as the "first vehicle") 1 and a second railway vehicle (hereinafter referred to as the "second vehicle") 2 that constitute a railway vehicle system TS according to one aspect of an embodiment of the present invention. For convenience, the longitudinal direction of the car bodies constituting each vehicle 1, 2 will be described assuming a situation in which the vehicle is traveling to the left in Figures 1A and 1B, with the left side on which vehicles 1, 2 are traveling being referred to as the "front side" and the right side opposite to the traveling side being referred to as the "rear side."

[0013] The first vehicle 1 will now be described. The first vehicle 1 is, for example, a stainless steel car body of a commuter train with three double-door doors. The first vehicle 1 is an A1 type operated by Company A. The body structure 1A constituting the first vehicle 1 includes a front body structure 1A1, a rear body structure 1A2, a pair of left and right side bodies 1A3, a roof body structure 1A4, and an underframe 1A5. The body structure 1A has a symmetrical structure in the width direction of the car body.

[0014] The side structure 1A3 is composed of multiple blocks in the longitudinal direction of the car body. Specifically, in the side structure 1A3, a front window section 10, a door section 13, a middle window section 11, a door section 13, a middle window section 11, a door section 13, and a rear window section 12 are arranged in this order from the front side. The front window section 10, the door section 13, the middle window section 11, the door section 13, the middle window section 11, the door section 13, and the rear window section 12 are joined together with adjacent sections in the longitudinal direction of the car body.

[0015] The front window section 10 is equipped with one front window 102. The middle window section 11 has two middle windows 112 formed at a predetermined interval in the longitudinal direction of the car body. The rear window section 12 is equipped with one rear window 122. The door section 13 is formed with a boarding / alighting opening 13H through which passengers get on and off. The door section 13 is equipped with a side door 132 that opens and closes the boarding / alighting opening 13H. The side door 132 is of a sliding opening and closing type. That is, the side door 132 is a set consisting of a front door 132A located on the front side and a rear door 132B located on the rear side. The front door 132A and the rear door 132B have a symmetrical structure in the longitudinal direction of the car body.

[0016] Although details will be described later, door end post units TU including door end posts 43 which function as vertical frames are erected near the rear side of the front window 102 of the front window section 10, near the rear side of the rear middle window 112 of the middle window section 11, and near the front side of the rear window 122 of the rear window section 12, and near the front side of the front middle window 112 of the middle window section 11. The door end post units TU erected near the rear side of the front window 102 of the front window section 10 and near the rear side of the rear middle window 112 of the middle window section 11 and the door end post units TU erected near the front side of the rear window 122 of the rear window section 12 and near the front side of the front middle window 112 of the middle window section 11 are symmetrical in the longitudinal direction of the vehicle body.

[0017] In the first vehicle 1, a space for storing a side door 132 so that it can be opened and closed is formed on the opposite side of each end door post unit TU from the windows 102, 112, 122 in the vehicle body longitudinal direction. This space is referred to as a "door pocket." Specifically, the door pocket formed on the opposite side (rear side) of the front window 102 of the end door post unit TU of the front window section 10 and the door pocket formed on the opposite side (rear side) of the middle window 112 of the end door post unit TU on the rear side of the middle window section 11 are referred to as the "front door pocket 101" and the "middle rear door pocket 111B," respectively. Similarly, the door pocket formed on the opposite side (front side) of the rear window 122 of the end door post unit TU of the rear window section 12 and the door pocket formed on the opposite side (front side) of the middle window 112 of the end door post unit TU on the front side of the middle window section 11 are referred to as the "rear door pocket 121" and the "middle front door pocket 111A," respectively. The middle front door pocket 111A and the middle rear door pocket 111B are collectively referred to as the "middle door pocket 111."

[0018] The front door pocket 101 and the center rear door pocket 111B store the front door 132A. Meanwhile, the rear door pocket 121 and the center front door pocket 111A store the rear door 132B. In a plan view, the front door pocket 101, the center rear door pocket 111B, the rear door pocket 121, and the center front door pocket 111A are mainly partitioned by side outer plates that constitute the side body structure 1A3, interior lining plates (not shown) that separate the interior space of the first vehicle 1, and the door end post unit TU. The front door pocket 101 and the center rear door pocket 111B are open on the rear side (i.e., an opening is formed through which the side door 132 enters and exits). Meanwhile, the rear door pocket 121 and the center front door pocket 111A are open on the front side.

[0019] The open end of each door pocket 101, 111, 121 in the carbody longitudinal direction is located at a position where the inner wall surface of the boarding / alighting opening 13H is formed in the carbody width direction. As will be described in detail later, boarding / alighting opening reinforcing frames 45 are installed at both ends of the door section 13 in the carbody longitudinal direction, on the outer peripheral edge of the boarding / alighting opening 13H in the carbody longitudinal direction. Therefore, strictly speaking, the front door pocket 101 is formed in the carbody width direction across a portion corresponding to the front window section 10 and a portion corresponding to the boarding / alighting opening reinforcing frame 45 of the door section 13 located behind it. Similarly, the rear door pocket 121 is formed in the carbody width direction across a portion corresponding to the rear window section 12 and a portion corresponding to the boarding / alighting opening reinforcing frame 45 of the door section 13 located in front of it. In addition, the middle front door pocket 111A and the middle rear door pocket 111B are formed in the width direction of the vehicle body, spanning the part corresponding to the middle window section 11 and the part corresponding to the boarding / alighting door reinforcing frame body 45 of the door section 13 located in front of and behind it.

[0020] However, in this embodiment, for convenience, the front door pocket 101 is assumed to be configured with a portion corresponding to the front window section 10 in the vehicle body width direction. Similarly, the rear door pocket 121 is assumed to be configured with a portion corresponding to the rear window section 12 in the vehicle body width direction. Furthermore, the middle front door pocket 111A and the middle rear door pocket 111B are assumed to be configured with portions corresponding to the middle window section 11 in the vehicle body width direction. The length L101 in the vehicle body longitudinal direction of the front door pocket 101, the length L121 in the vehicle body longitudinal direction of the rear door pocket 121, the length L111A in the vehicle body longitudinal direction of the middle front door pocket 111A, and the length L111B in the vehicle body longitudinal direction of the middle rear door pocket 111B are all the same.

[0021] The second vehicle 2 will now be described. The second vehicle 2 is a different type of railway vehicle from the first vehicle 1. The second vehicle 2 is, for example, a stainless steel body of a commuter train with four double-door doors. The second vehicle 2 is a B1 type operated by Company B. The body structure 2A constituting the second vehicle 2 includes a front body structure 2A1, a rear body structure 2A2, a pair of left and right side bodies 2A3, a roof body structure 2A4, and an underframe 2A5. The body structure 2A has a symmetrical structure in the width direction of the car body.

[0022] The side structure 2A3 is composed of multiple blocks in the longitudinal direction of the car body. Specifically, in the side structure 2A3, a front window section 20, a door section 23, a center window section 21, a door section 23, a center window section 21, a door section 23, a center window section 21, a door section 23, and a rear window section 22 are arranged in this order from the front side. The front window section 20, the door section 23, the center window section 21, the door section 23, the center window section 21, the door section 23, the center window section 21, the door section 23, and the rear window section 22 are joined together with adjacent sections in the longitudinal direction of the car body.

[0023] The front window section 20 is equipped with one front window 202. The middle window section 21 is equipped with one middle window 212. The rear window section 22 is equipped with one rear window 222. The door section 23 is formed with a boarding / alighting opening 23H through which passengers get on and off. The door section 23 is equipped with a side door 232 that opens and closes the boarding / alighting opening 23H. The side door 232 is of a sliding opening and closing type. That is, the side door 232 is a set consisting of a front door 232A located on the front side and a rear door 232B located on the rear side. The front door 232A and the rear door 232B are symmetrical in the longitudinal direction of the car body.

[0024] As with the first vehicle 1, end post units TU including end posts 43 functioning as vertical frames are erected near the rear side of the front window 202 of the front window section 20, near the rear side of the middle window 212 of the middle window section 21, and near the front side of the rear window 222 of the rear window section 22, and near the front side of the middle window 212 of the middle window section 21. The end post units TU erected near the rear side of the front window 202 of the front window section 20 and near the rear side of the middle window 212 of the middle window section 21 and the end post units TU erected near the front side of the rear window 222 of the rear window section 22 and near the front side of the middle window 212 of the middle window section 21 are symmetrical in the longitudinal direction of the vehicle body.

[0025] In the second vehicle 2, similarly to the first vehicle 1, a front door pocket 201, a rear door pocket 221, a central front door pocket 211A (211), and a central rear door pocket 211B (211) are formed.

[0026] The length L201 of the front door pocket 201 in the longitudinal direction of the vehicle body, the length L221 of the rear door pocket 221 in the longitudinal direction of the vehicle body, the length L211A of the middle front door pocket 211A in the longitudinal direction of the vehicle body, and the length L211B of the middle rear door pocket 211B in the longitudinal direction of the vehicle body are the same.

[0027] Furthermore, the lengths L101, L111, L121 of the door pockets 101, 111, 121 of the first car 1 in the longitudinal direction of the car body are the same as the lengths L201, L211, L221 of the door pockets 201, 211, 221 of the second car 2 in the longitudinal direction of the car body. In addition, a common end post unit TU is used in the first car 1 and the second car 2. However, strictly speaking, the end post unit TU that houses the front doors 132A, 232A and the end post unit TU that houses the rear doors 132B, 232B do not have completely identical structures, but because they are symmetrical in the longitudinal direction of the car body, they are considered to have substantially the same structure. Furthermore, since the tail post unit TU in which the front doors 132A, 232A are housed and the tail post unit TU in which the rear doors 132B, 232B are housed are substantially of the same structure, the tail post 43 associated with the tail post unit TU in which the front doors 132A, 232A are housed and the tail post 43 associated with the tail post unit TU in which the rear doors 132B, 232B are housed are also substantially of the same structure.

[0028] In this way, the lengths L101, L111, L121 of each door pocket 101, 111, 121 in the carbody longitudinal direction, the structure of the door end post 43 (shape and dimensions of each part related to the shape), and the structure of the door end post unit TU of the first car 1 are identical to the lengths L201, L211, L221 of each door pocket 201, 211, 221 in the carbody longitudinal direction, the structure of the door end post 43 (shape and dimensions of each part related to the shape), and the structure of the door end post unit TU of the second car 2. Therefore, the first car 1 and the second car 2 form a railway car system TS in which the lengths of each door pocket in the carbody longitudinal direction, the structure of the door end post 43 (shape and dimensions of each part related to the shape), and the structure of the door end post unit TU are common.

[0029] Next, the structure around the end post unit TU will be described. As mentioned above, the end post units TU installed in the front window section 10, middle window section 11, and rear window section 12 of the first vehicle 1 and the end post units TU installed in the front window section 20, middle window section 21, and rear window section 22 of the second vehicle 2 have a common structure, so here, the structure around the end post unit TU installed in the middle window section 21 of the second vehicle 2 will be used as a representative example for description. Figure 2 is a partial side view of one door section 23 of the second vehicle 2 and the middle window sections 21 joined to both sides of it, as seen from the vehicle interior side.

[0030] The middle window section 21 includes a side outer panel 40, a cross member 41, a shear plate 42, and a door end post unit TU including a door end post 43. The door section 23 includes an entrance reinforcing frame 45 for reinforcing the entrance 23H. The entrance reinforcing frame 45 is a rectangular frame that corresponds overall to the entrance 23H.

[0031] The shear plates 42 are joined to the side outer panels 40 between both outer edges of each middle window opening 21H in the longitudinal direction of the car body and both ends of the middle window section 21 in the longitudinal direction of the car body. In addition, a middle window frame 44 for attaching the middle window 212 is attached to the peripheral edge of the middle window opening 21H. The middle window frame 44 is fixed to the end post unit TU.

[0032] The end post unit TU is erected near the entrance 23H side of the middle window opening 21H. The end post unit TU is fitted over the cross frame member 41 from the inside of the vehicle, intersecting the cross frame member 41 at a substantially right angle, and joined by laser welding. The end post unit TU will be described later.

[0033] The cross frame members 41 consist of three upper cross frame members 411, two middle cross frame members 412, and five lower cross frame members 413. The three upper cross frame members 411 are arranged at a predetermined interval in the vertical direction in the area above the middle window opening 21H (the header board portion). The five lower cross frame members 413 are arranged at a predetermined interval in the vertical direction in the area below the middle window opening 21H (the waist board portion). The two middle cross frame members 412 are arranged at a predetermined interval in the vertical direction in the area above the middle window opening 21H. Each upper cross frame member 411 and each lower cross frame member 413 is joined to the interior surface of the side outer panel 40. Each middle cross frame member 412 is joined to the interior surface of the shear plate 42.

[0034] Each transverse bone member 41 is composed of a columnar member having a hat-shaped cross section (orthogonal cross section) perpendicular to the longitudinal direction of the transverse bone member 41 (transverse bone longitudinal direction). The orthogonal cross section of each transverse bone member 41 is constant in the transverse bone longitudinal direction. Figure 3A shows the orthogonal cross section of the upper transverse bone member 411, Figure 3B shows the orthogonal cross section of the middle transverse bone member 412, and Figure 3C shows the orthogonal cross section of the lower transverse bone member 413.

[0035] The orthogonal cross section of the upper cross member 411 has a protrusion 411A and a pair of flanges 411B. The protrusion 411A is U-shaped. More specifically, the protrusion 411A has a top plate 411A1 and a pair of side walls 411A2. In the orthogonal cross section of the upper cross member 411, the side walls 411A2 are bent at approximately a right angle from both ends of the top plate 411A1 at one end. The flanges 411B are bent at approximately a right angle from the other end of each side wall 411A2 facing outward. The lengths of each side wall 411A2 in the extending direction are the same.

[0036] Similar to the upper cross-section member 411, the orthogonal cross-section of the middle cross-section member 412 has a protrusion 412A, a pair of flanges 412B, a top plate 412A1, and a pair of side walls 412A2. Similar to the upper cross-section member 411, the orthogonal cross-section of the lower cross-section member 413 has a protrusion 413A, a pair of flanges 413B, a top plate 413A1, and a pair of side walls 413A2. Note that the orthogonal cross-sections of each cross-section member 411-413 are not limited to the shape shown in FIGS. 3A-3C, in which the top plate 411A1, 412A1, 413A1 and both side walls 411A2, 412A2, 413A2 are substantially perpendicular to each other. For example, the angle formed between the top plate portions 411A1, 412A1, 413A1 and one of the side wall portions 411A2, 412A2, 413A2 may be 120 degrees, and the angle between the top plate portions 411A1, 412A1, 413A1 and the other of the side wall portions 411A2, 412A2, 413A2 may be 60 degrees, as long as the pair of flange portions 411B, 412B, 413B are on the same plane. Furthermore, the orthogonal cross sections of the cross frame members 411-413 may be different from each other.

[0037] In the following, in the orthogonal cross section of each transverse bone member 411, 412, 413, the direction in which the side wall portions 411A2, 412A2, 413A2 extend is referred to as the "transverse bone cross-sectional height direction," and the direction perpendicular to the direction in which the side wall portions 411A2, 412A2, 413A2 extend, in other words, the direction in which the top plate portions 411A1, 412A1, 413A1 and flange portions 411B, 412B, 413B extend, is referred to as the "transverse bone cross-sectional width direction."

[0038] Each of the cross frame members 411, 412, and 413 is formed by bending a single plate-like member of the same thickness. Therefore, the thickness of the flange portion 411B of the upper cross frame member 411, the thickness of the flange portion 412B of the middle cross frame member 412, and the thickness of the flange portion 413B of the lower cross frame member 413 are the same. Furthermore, the length of the protruding portion 411A of the upper cross frame member 411 in the cross frame cross-sectional height direction is shorter than the length of the protruding portion 412A of the middle cross frame member 412 in the cross frame cross-sectional height direction and the length of the protruding portion 413A of the lower cross frame member 413 in the cross frame cross-sectional height direction. This is to ensure space above the middle window opening 21H for arranging devices for opening and closing the side door 132. Furthermore, the length of the protruding portion 413A of the lower transverse member 413 in the transverse bone cross-sectional height direction is longer than the length of the protruding portion 412A of the middle transverse member 412 in the transverse bone cross-sectional height direction by the thickness of the shear plate 42.

[0039] The upper cross frame member 411 is joined to the interior surface of the side outer panel 40 at the surface opposite the top plate portion 411A1 of the pair of flange portions 411B. Similarly, the lower cross frame member 413 is joined to the interior surface of the side outer panel 40 at the surface opposite the top plate portion 413A1 of the pair of flange portions 413B. The middle cross frame member 412 is joined to the interior surface of the shear plate 42 at the surface opposite the top plate portion 412A1 of the pair of flange portions 412B. Therefore, the position of the top plate portion 412A1 of the middle cross frame member 412 in the cross frame cross section height direction is the same as the position of the top plate portion 413A1 of the lower cross frame member 413 in the cross frame cross section height direction.

[0040] Next, we will explain the end post 43 that constitutes the end post unit TU. Figures 4A and 4B are perspective views of the end post 43 seen from different angles. Figures 5A, 5B, and 5C are cross-sectional end views taken along lines AA, BB, and CC in Figure 4B, respectively. This end post unit TU is located near the left side of the inner window opening 21H on the right side in Figure 2.

[0041] The tail post 43 is a columnar member that extends long in one direction overall. The tail post 43 is roughly divided into an upper tail post portion 43A, a middle tail post portion 43B, and a lower tail post portion 43C along its longitudinal direction (the column longitudinal direction). In terms of the column longitudinal length, the middle tail post portion 43B is the longest and the upper tail post portion 43A is the shortest.

[0042] When the end post unit TU is installed, the longitudinal direction of the post is parallel to the vertical direction. Also, when the end post unit TU is installed, in the vertical direction, the end post upper part 43A is located above the middle window opening 21H, the end post lower part 43C is located below the middle window opening 21H, and the end post middle part 43B is located within the middle window opening 21H.

[0043] The tail post 43 is made by bending a single flat plate in various ways. A base plate 431 having the same width over the entire length of the tail post 43 is formed on the tail post 43. That is, the base plate 431 is formed continuously over the tail post upper part 43A, the tail post middle part 43B, and the tail post lower part 43C.

[0044] Hereinafter, the portion of the base plate portion 431 at the door end post upper portion 43A, the portion of the base plate portion 431 at the door end post middle portion 43B, and the portion of the base plate portion 431 at the door end post lower portion 43C will be referred to as the "upper base plate portion 431A," the "middle base plate portion 431B," and the "lower base plate portion 431C," respectively. When the door end post unit TU is installed, the base plate portion 431 is approximately perpendicular to the floor surface. When the door end post unit TU is installed, the width direction of the base plate portion 431 is parallel to the longitudinal direction of the car body. The base plate portion 431 is located at the innermost part of the door end post 43.

[0045] Furthermore, the end post 43 is formed, over the entire longitudinal length of the post, with a door side plate 432 and a window side plate 433 that face each other in a direction perpendicular to the longitudinal direction of the post. In a cross section perpendicular to the longitudinal direction of the post (a cross section perpendicular to the post), the door side plate 432 is bent at a substantially right angle from one widthwise end of the base plate 431, and the window side plate 433 is bent at a substantially right angle from the other widthwise end of the base plate 431. The door side plate 432 and the window side plate 433 are formed continuously over the end post upper part 43A, the end post middle part 43B, and the end post lower part 43C.

[0046] Hereinafter, the portion of the door side panel 432 at the end post upper portion 43A, the portion of the door side panel 432 at the end post middle portion 43B, and the portion of the door side panel 432 at the end post lower portion 43C will be referred to as the "upper door side panel 432A," the "middle door side panel 432B," and the "lower door side panel 432C," respectively. Similarly, the portion of the window side panel 433 at the end post upper portion 43A, the portion of the window side panel 433 at the end post middle portion 43B, and the portion of the window side panel 433 at the end post lower portion 43C will be referred to as the "upper window side panel 433A," the "middle window side panel 433B," and the "lower window side panel 433C," respectively.

[0047] When the end post unit TU is installed, the door side plate portion 432 is approximately perpendicular to the side outer plate 40 and is located closer to the entrance 113 than the base plate portion 431. On the other hand, when the end post unit TU is installed, the window side plate portion 433 is approximately perpendicular to the side outer plate 40 and is located closer to the middle window opening 21H than the base plate portion 431.

[0048] Note that the direction in which the base plate portion 431 extends when viewed in a column orthogonal cross section, in other words, the width direction of the base plate portion 431, is referred to as the "column cross-sectional width direction." Furthermore, the direction perpendicular to the column cross-sectional width direction when viewed in a column orthogonal cross section, in other words, the direction in which the door side panel portion 432 and the window side panel portion 433 extend, is referred to as the "column cross-sectional height direction." Furthermore, in the door end post 43, the side surrounded by the base plate portion 431, the door side panel portion 432, and the window side panel portion 433 is referred to as the "inside," and the side opposite the inside with respect to the base plate portion 431, the door side panel portion 432, and the window side panel portion 433 is referred to as the "outside."

[0049] A door-side flange 434 is formed at the end of the door side plate 432 opposite the base plate 431 in the column cross-sectional height direction. The door-side flange 434 is bent outward at approximately a right angle from the door side plate 432. Furthermore, a window-side flange 435 is formed at the end of the window side plate 433 opposite the base plate 431 in the column cross-sectional height direction. The window-side flange 435 is bent outward at approximately a right angle from the window side plate 433. Therefore, the door-side flange 434 and the window-side flange 435 are parallel to the base plate 431.

[0050] Hereinafter, the portion of the door-side flange portion 434 at the end post upper portion 43A, the portion of the door-side flange portion 434 at the end post middle portion 43B, and the portion of the door-side flange portion 434 at the end post lower portion 43C will be referred to as the "upper door-side flange portion 434A," the "middle door-side flange portion 434B," and the "lower door-side flange portion 434C," respectively. Similarly, the portion of the window-side flange portion 435 at the end post upper portion 43A, the portion of the window-side flange portion 435 at the end post middle portion 43B, and the portion of the window-side flange portion 435 at the end post lower portion 43C will be referred to as the "upper window-side flange portion 435A," the "middle window-side flange portion 435B," and the "lower window-side flange portion 435C," respectively. When the end post unit TU is installed, the door-side flange portion 434 and the window-side flange portion 435 are located closer to the vehicle exterior than the base plate portion 431.

[0051] A closing plate portion 436 is formed at the end of the door-side flange portion 434 opposite the door side plate portion 432 in the column cross-sectional width direction. The closing plate portion 436 is bent at a substantially right angle from the door-side flange portion 434 to the opposite side of the base plate portion 431 in the column cross-sectional height direction. Therefore, the closing plate portion 436 is substantially parallel to the door side plate portion 432 and the window side plate portion 433.

[0052] Hereinafter, the portion of the closing plate 436 at the end post upper portion 43A, the portion of the closing plate 436 at the end post middle portion 43B, and the portion of the closing plate 436 at the end post lower portion 43C will be referred to as the "upper closing plate 436A," the "middle closing plate 436B," and the "lower closing plate 436C," respectively. When the end post unit TU is installed, the closing plate 436 is approximately perpendicular to the side outer panel 40.

[0053] Three upper transverse bone notches 440A are formed in the upper closing plate 436A along the column longitudinal direction. The protruding portions 411A of the upper transverse bone members 411 arranged along the vertical direction are fitted into each upper transverse bone notch 440A. That is, the column longitudinal length of the upper transverse bone notch 440A is the same as the transverse bone cross-sectional width length of the protruding portions 411A of the upper transverse bone member 411. Furthermore, the column cross-sectional height length of the upper transverse bone notch 440A is the same as the transverse bone cross-sectional height length of the protruding portions 411A of the upper transverse bone member 411. Furthermore, the column cross-sectional height length of the upper transverse bone notch 440A is also the same as the column cross-sectional height length of the upper closing plate 436A.

[0054] Two central transverse bone notches 440B are formed in the central covering plate 436B along the column longitudinal direction. The protruding portions 412A of the central transverse bone members 412 arranged along the vertical direction are fitted into each central transverse bone notch 440B formed in the central covering plate 436B. That is, the column longitudinal length of the central transverse bone notch 440B is the same as the transverse bone cross-sectional width length of the protruding portions 412A of the central transverse bone member 412. Furthermore, the column cross-sectional height length of the central transverse bone notch 440B is the same as the transverse bone cross-sectional height length of the protruding portions 412A of the central transverse bone member 412. Furthermore, the column cross-sectional height length of the central transverse bone notch 440B is also the same as the column cross-sectional height length of the central covering plate 436B.

[0055] Five lower transverse bone notches 440C are formed in the lower closing plate 436C along the column longitudinal direction. The protruding portions 413A of the lower transverse bone members 413 arranged along the vertical direction are fitted into each lower transverse bone notch 440C formed in the lower closing plate 436C. That is, the column longitudinal length of the lower transverse bone notch 440C is the same as the transverse bone cross-sectional width length of the protruding portions 413A of the lower transverse bone member 413. Furthermore, the column cross-sectional height length of the lower transverse bone notch 440C is the same as the transverse bone cross-sectional height length of the protruding portions 413A of the lower transverse bone member 413. Furthermore, the column cross-sectional height length of the lower transverse bone notch 440C is also the same as the column cross-sectional height length of the lower closing plate 436C.

[0056] Four middle insertion holes 441B, into which insertion pieces 50B of a window frame support member 50 described below are inserted, are formed at equal intervals along the column longitudinal direction from the middle window side plate portion 433B to the end of the middle base plate portion 431B on the middle window side plate portion 433B side. Furthermore, three middle rivet insertion holes 442B, into which rivets 54 for fastening the door end post 43 and the window frame support member 50 are inserted, are formed near the middle insertion holes 441B in the middle base plate portion 431B (in this embodiment, two are near the middle insertion holes 441B and one is located toward the center of the middle base plate portion 431B, arranged in a triangle).

[0057] A single lower insertion hole 441C is formed from the lower window side panel 433C to the end of the lower base plate 431C on the lower window side panel 433C side, into which an insertion piece 51B of an interior panel receiving member 51, which will be described later, is inserted. Furthermore, three lower rivet insertion holes 442C, into which rivets 55 for fastening the door end post 43 and the interior panel receiving member 51 are inserted, are formed near the lower insertion hole 441C in the lower base plate 431C.

[0058] Next, we will explain the dimensions of each part of the basic cross-sectional shape perpendicular to the height direction of the end post upper part 43A, end post middle part 43B, and end post lower part 43C. Note that the basic cross-sectional shape refers to the cross-sectional shape of the part without any notches or holes. In addition, in the column orthogonal cross section of the end post 43, the length in the column cross-sectional width direction is referred to as "width," and the length in the column cross-sectional height direction is referred to as "height."

[0059] The width W11 of the upper substrate portion 431A, the width W21 of the middle substrate portion 431B, and the width W31 of the lower substrate portion 431C are the same. That is, the width of the substrate portion 431 of the door end post 43 is constant along the column longitudinal direction. The width W12 of the upper door-side flange portion 434A, the width W22 of the middle door-side flange portion 434B, and the width W32 of the lower door-side flange portion 434C are the same. That is, the width of the door-side flange portion 434 of the door end post 43 is constant along the column longitudinal direction. The width W13 of the upper window-side flange portion 435A, the width W23 of the middle window-side flange portion 435B, and the width W33 of the lower window-side flange portion 435C are the same. That is, the width of the window-side flange portion 435 of the door end post 43 is constant along the column longitudinal direction. The width of the base plate portion 431 is greater than the width of the door-side flange portion 434 and the width of the window-side flange portion 435. The width of the window-side flange portion 435 is smaller than the width of the door-side flange portion 434.

[0060] The width W11 of the upper substrate portion 431A includes the thickness of the upper door side plate portion 432A and the thickness of the upper window side plate portion 433A. The same applies to the width W21 of the middle substrate portion 431B and the width W31 of the lower substrate portion 431C. Furthermore, the width W12 of the upper door flange portion 434A does not include the thickness of the upper door side plate portion 432A, but does include the thickness of the upper closing plate portion 436A. The same applies to the width W22 of the middle door flange portion 434B and the width W32 of the lower door flange portion 434C. Furthermore, the width W13 of the upper window flange portion 435A does not include the thickness of the upper window side plate portion 433A. The same applies to the width W23 of the middle window flange portion 435B and the width W33 of the lower window flange portion 435C.

[0061] The height H11 of the upper door side panel 432A is the same as the height H12 of the upper window side panel 433A. The height H22 of the middle window side panel 433B is longer than the height H21 of the middle door side panel 432B. The height H31 of the lower door side panel 432C is the same as the height H32 of the lower window side panel 433C. Furthermore, the height H21 of the middle door side panel 432B is the same as the height H31 of the lower door side panel 432C and the height H32 of the lower window side panel 433C. The height H21 of the middle door side panel 432B is shorter than the height H11 of the upper door side panel 432A and the height H12 of the upper window side panel 433A. The height H22 of the middle window side panel 433B is longer than the height H11 of the upper door side panel 432A and the height H12 of the upper window side panel 433A. Therefore, the interrelationship between the heights of each part of the door side panel portion 432 and the heights of each part of the window side panel portion 433 can be summarized as follows: height H22 of middle window side panel portion 433B > height H11 of upper door side panel portion 432A = height H12 of upper window side panel portion 433A > height H21 of middle door side panel portion 432B = height H31 of lower door side panel portion 432C = height H32 of lower window side panel portion 433C.

[0062] The height H11 of the upper door side plate portion 432A includes the thickness of the upper base plate portion 431A and the thickness of the upper door flange portion 434A. The same is true for the height H21 of the middle door side plate portion 432B and the height H31 of the lower door side plate portion 432C. The height H12 of the upper window side plate portion 433A includes the thickness of the upper base plate portion 431A and the thickness of the upper window flange portion 435A. The same is true for the height H22 of the middle window side plate portion 433B and the height H32 of the lower window side plate portion 433C.

[0063] With the door end post unit TU installed, the cross-sectional width direction of the pillar is parallel to the longitudinal direction of the car body. The positional relationship of each part of the door end post 43 with respect to the width direction of the car body is based on the position of the base plate portion 431. As a result, as the height of each part of the door side plate portion 432 and the height of each part of the window side plate portion 433 increases, each part of the door-side flange portion 434 and the window-side flange portion 435 becomes closer to the interior surface of the side outer plate 40, and as the height of each part of the door side plate portion 432 and the height of each part of the window side plate portion 433 decreases, each part of the door-side flange portion 434 and the window-side flange portion 435 becomes farther from the interior surface of the side outer plate 40.

[0064] When the end post unit TU is installed, the exterior surface of the upper door-side flange portion 434A and the exterior surface of the upper window-side flange portion 435A abut against the interior surface of the top plate portion 411A1 of the upper cross frame member 411. Furthermore, when the end post unit TU is installed, the exterior surface of the lower door-side flange portion 434C and the exterior surface of the lower window-side flange portion 435C abut against the interior surface of the top plate portion 413A1 of the lower cross frame member 413. Furthermore, when the end post unit TU is installed, the exterior surface of the middle door-side flange portion 434B abuts against the interior surface of the top plate portion 412A1 of the middle cross frame member 412. Meanwhile, when the end post unit TU is installed, the exterior surface of the middle window-side flange portion 435B abuts against the shear plate 42. The end of the middle cross frame member 412 closer to the middle window opening 21H in the longitudinal direction of the car body is located inside the door end post 43, in other words, between the middle door side plate portion 432B and the middle window side plate portion 433B. In this embodiment, the end of the middle cross frame member 412 closer to the middle window opening 21H in the longitudinal direction of the car body is formed up to the vicinity of the middle window side plate portion 433B.

[0065] Here, the end post 43 is made of a single plate-like member, so the thickness of each base plate portion 431A, 431B, 431C is the same as the thickness of each door side plate portion 432A, 432B, 432C, and the thickness of each window side plate portion 433A, 433B, 433C. Furthermore, when the end post unit TU is installed, a shear plate 42 is attached to the area facing the end post middle portion 43B in the vehicle width direction.

[0066] Therefore, the height H22 of the middle window side panel 433B is longer than the height H11 of the upper door side panel 432A and the height H12 of the upper window side panel 433A by the amount obtained by subtracting the thickness of the shear plate 42 from the length of the cross-section height direction of the upper cross frame member 411. Similarly, the height H22 of the middle window side panel 433B is longer than the height H31 of the lower door side panel 432C and the height H32 of the lower window side panel 433C by the amount obtained by subtracting the thickness of the shear plate 42 from the length of the cross-section height direction of the lower cross frame member 413. Furthermore, the height H22 of the middle window side panel 433B is longer than the height H21 of the middle door side panel 432B by the length of the cross-section height direction of the middle cross frame member 412.

[0067] Furthermore, the height H11 of the upper door side panel 432A and the height H12 of the upper window side panel 433A are longer than the height H31 of the lower door side panel 432C and the height H32 of the lower window side panel 433C by the amount obtained by subtracting the length of the cross-section height of the upper cross panel 411 from the length of the cross-section height of the lower cross panel 413. Also, the height H11 of the upper door side panel 432A and the height H12 of the upper window side panel 433A are longer than the height H21 of the middle door side panel 432B by the amount obtained by subtracting the length of the cross-section height of the upper cross panel 411 from the length of the cross-section height of the middle cross panel 412, and then adding the thickness of the shear plate 42. Also, the height H21 of the middle door side panel 432B is the same as the height H31 of the lower door side panel 432C and the height H32 of the lower window side panel 433C.

[0068] As described above, the basic cross-sectional shape of the door end post 43 perpendicular to the post longitudinal direction, particularly the height of the door side plate portion 432 and the height of the window side plate portion 433, vary along the post longitudinal direction depending on the components arranged on the vehicle exterior side (the cross frame member 41 and the shear plate 42). In other words, the heights of the door side plate portion 432 and the window side plate portion 433 vary along the post longitudinal direction depending on the length of the cross frame member 41 in the cross frame cross section height direction and the presence or absence of the shear plate 42. As a result, the door side flange portion 434, which is bent at a substantially right angle to the door side plate portion 432, and the window side flange portion 435, which is bent at a substantially right angle to the window side plate portion 433, have a stepped structure in the vehicle width direction. In other words, the distances from the base plate portions 431A, 431B, 431C of the door-side flange portions 434A, 434B, 434C and the window-side flange portions 435A, 435B, 435C also vary depending on the door side plate portions 432A, 432B, 432C and the window side plate portions 433A, 433B, 433C. The "distance" here refers to the distance from the interior surface of the base plate portions 431A, 431B, 431C to the interior surface of the door-side flange portions 434A, 434B, 434C and the window-side flange portions 435A, 435B, 435C in the car body width direction (pillar cross-sectional height direction). Therefore, each distance is calculated by subtracting the thickness of the door end post 43 from the height of each door side panel portion 432A, 432B, 432C and each window side panel portion 433A, 433B, 433C formed between each base plate portion 431A, 431B, 431C and each door side flange portion 434A, 434B, 434C, and each window side flange portion 435A, 435B, 435C.

[0069] Additionally, the upper closing plate portion 436A abuts against the interior surface of the flange portion 411B of the upper cross frame member 411. The middle closing plate portion 436B abuts against the interior surface of the flange portion 412B of the middle cross frame member 412. The lower closing plate portion 436C abuts against the interior surface of the flange portion 413B of the lower cross frame member 413.

[0070] The height H13 of the upper closing plate 436A is the same as the length of the cross-sectional height of the protruding portion 411A of the upper cross-bone member 411. The height H23 of the middle closing plate 436B is the same as the length of the cross-sectional height of the protruding portion 412A of the middle cross-bone member 412. The height H33 of the lower closing plate 436C is the same as the length of the cross-sectional height of the protruding portion 413A of the lower cross-bone member 413. In other words, the upper closing plate 436A, the middle closing plate 436B, and the lower closing plate 436C close the gaps between the cross-bone members 41 that are arranged side by side in the vertical direction relative to the longitudinal direction of the vehicle body.

[0071] Next, we will explain the gaps formed in the end post 43 where the door-side flange 434 has a stepped structure and where the window-side flange 435 has a stepped structure. Figure 6A is a front view of the end post 43 as seen from the base plate 431 side in the column cross-sectional height direction. Figure 6B is a side view of the end post 43 as seen from the door side plate 432 side in the column cross-sectional width direction. Figure 6C is a side view of the end post 43 as seen from the window side plate 433 side in the column cross-sectional width direction. Hereinafter, the end post upper portion 43A side in the column longitudinal direction will be referred to as the "upper side," and the end post lower portion 43C side in the column longitudinal direction will be referred to as the "lower side." Furthermore, the door side plate 432 side in the column cross-sectional width direction will be referred to as the "door side," and the window side plate 433 side in the column cross-sectional width direction will be referred to as the "window side." Furthermore, the base plate 431 side in the column cross-sectional height direction will be referred to as the "convex side."

[0072] A door-side first step gap 444A is formed near the lower side of the lowermost upper horizontal bone cutout 440A. The door-side first step gap 444A completely separates the upper door-side flange portion 434A and the middle door-side flange portion 434B, and also completely separates the upper door closing plate portion 436A and the middle door closing plate portion 436B. In other words, when viewed from the front from the convex side, a gap of a certain width (shorter than the column cross-sectional width direction length of the upper door-side flange portion 434A and the column cross-sectional width direction length of the middle door-side flange portion 434B) is formed between the upper door-side flange portion 434A and the middle door-side flange portion 434B. In addition, when viewed from the side from the door side, a gap of a certain width (shorter than the column cross-sectional height direction length of the upper blocking plate portion 436A and the column cross-sectional height direction length of the middle blocking plate portion 436B) is formed between the upper blocking plate portion 436A and the middle blocking plate portion 436B.

[0073] A window-side first step gap 445A and a window-side second step gap 445B are formed on the opposite side of the door-side flange portion 434 across the base plate portion 431 of the door end post 43. The window-side first step gap 445A is formed in approximately the same position as the door-side first step gap 444A in the pillar longitudinal direction. On the other hand, the window-side second step gap 445B is formed in the same position as the upper side of the lower horizontal bone notch 440C, which is formed at the uppermost position in the pillar longitudinal direction.

[0074] The window-side first step gap 445A completely separates the upper window-side flange portion 435A and the middle window-side flange portion 435B. That is, when viewed from the front from the convex side, a gap of a constant width (shorter than the column cross-sectional width direction length of the upper window-side flange portion 435A and the column cross-sectional width direction length of the middle window-side flange portion 435B) is formed between the upper window-side flange portion 435A and the middle window-side flange portion 435B. Furthermore, the window-side second step gap 445B completely separates the middle window-side flange portion 435B and the lower window-side flange portion 435C. That is, when viewed from the front from the convex side, a gap of a constant width (shorter than the column cross-sectional width direction length of the middle window-side flange portion 435B and the column cross-sectional width direction length of the lower window-side flange portion 435C) is formed between the middle window-side flange portion 435B and the lower window-side flange portion 435C.

[0075] Next, the tail post unit TU will be described. Fig. 7 is a perspective view of the tail post unit TU. The tail post unit TU includes a tail post 43, a window frame receiving member 50, a lining board receiving member 51, a side door receiving member 52, and a pipe receiving member 53.

[0076] The end post 43 functions as a vertical frame of the middle window section 21 that constitutes the side body structure 2A3, and forms the core of the end post unit TU. The window frame support member 50 is a member for joining the middle window frame 44 and the end post 43. The lining plate support member 51 is a member for joining the end post 43 and an interior lining plate (not shown) that divides the interior space of the vehicle. The side door support member 52 is a member for receiving a buffer member (not shown) provided at the end of the side door 232 facing the end post unit TU when the side door 232 is opened. The piping support member 53 is a member for receiving piping that protects the wiring on the end post 43.

[0077] In this way, the door end post unit TU includes not only the structurally important door end post 43, but also the window frame support member 50, the interior panel support member 51, the side door support member 52, and the pipe support member 53, making the door end post 43 multifunctional as a hub for efficiently installing various interior fittings by consolidating them in one place.

[0078] The window frame support member 50 is made of a plate-like member. The window frame support member 50 has a substantially rectangular main body 50A that is long in one direction, and four insertion pieces 50B that protrude in the short-side direction from one edge of the main body 50A. The long-side length of the window frame support member 50, in other words, the main body 50A, is substantially the same as the column longitudinal length of the end post middle portion 43B. The short-side length of the insertion pieces 50B is 1 / 3 to 1 / 2 of the column cross-sectional width direction length of the middle base plate portion 431B. Each of the four insertion pieces 50B is inserted into a middle insertion hole 441B.

[0079] The window frame receiving member 50 is fixed to the door end post 43 by crimping the insertion pieces 50B inserted into the respective middle insertion holes 441B with the insertion pieces 50B in contact with the inner surface of the middle base plate portion 431B using three rivets 54. Furthermore, when the window frame receiving member 50 is fixed to the door end post 43, the side surface of the main body portion 50A facing the insertion pieces 50B is in contact with the middle window side panel portion 433B. The middle window frame 44 is then joined to the main body portion 50A. Furthermore, when the window frame receiving member 50 is fixed to the door end post 43, the main body portion 50A is formed in approximately the same area as the middle base plate portion 431B in the pillar longitudinal direction of the door end post 43.

[0080] The interior lining plate receiving member 51 is made of a plate-like member. The interior lining plate receiving member 51 has a generally rectangular main body 51A that is long in one direction, and one insertion piece 51B that protrudes in the short-side direction from one edge of the main body 51A. The length of the long side of the interior lining plate receiving member 51, or in other words, the length of the main body 51A, is shorter than the length of the lower end post 43C in the column longitudinal direction. The length of the insertion piece 51B in the short-side direction is 1 / 3 to 1 / 2 of the column cross-sectional width direction length of the lower base plate portion 431C. The insertion piece 51B is inserted into the lower insertion hole 441C.

[0081] The insertion piece 51B inserted into the lower insertion hole 441C is in contact with the inner surface of the lower base plate portion 431C and is fastened with three rivets 55, thereby fixing the lining plate receiving member 51 to the end post 43. Furthermore, when the lining plate receiving member 51 is fixed to the end post 43, the side surface of the insertion piece 51B of the main body portion 51A abuts against the lower window side plate portion 433C. A lining plate (not shown) is then joined to the main body portion 51A. Furthermore, when the lining plate receiving member 51 is fixed to the end post 43, the main body portion 51A is contained within the range of the lower base plate portion 431C in the pillar longitudinal direction of the end post 43.

[0082] The side door receiving member 52 has a main body 52A, a pair of legs 52B, and a receiving portion 52C. The main body 52A is a rectangular flat plate. Each of the pair of legs 52B is also a rectangular flat plate. Each of the pair of legs 52B is formed in a state where it is bent at a substantially right angle at an edge on one side of the main body 52A. The receiving portion 52C is formed in a state where it is bent at a substantially right angle slightly outside the edge on one side of the main body 52A on the opposite side to the pair of legs 52B.

[0083] Between the pair of leg portions 52B, a gap 52D is formed which has the same shape as the center horizontal bone notch 440B formed on the lower side. Then, the main body portion 52A is joined to the middle door-side flange portion 434B from the outside of the door end post 43, and the pair of leg portions 52B are joined to the middle closing plate portion 436B so that the gap 52D and the center horizontal bone notch 440B formed on the lower side overlap in the column cross-sectional width direction. In other words, the side door receiving member 52 is installed so as to surround the middle horizontal bone notch 440B formed on the lower side.

[0084] The side door receiving member 52 is fixed to the tail post 43 by fastening it to bolts 56 at four locations. When the side door receiving member 52 is fixed to the tail post 43, the receiving portion 52C is positioned slightly outside the middle closing plate portion 436B in the cross-sectional width direction of the tail post 43, facing the middle door side plate portion 432B and parallel to the middle door side plate portion 432B. When the tail post unit TU is installed, the side door 232 that has performed the opening operation comes into contact with the receiving portion 52C. In other words, the receiving portion 52C locks the side door 232 that has performed the opening operation. Therefore, the side door 232 does not move toward the middle window 212 from the receiving portion 52C along the vehicle body longitudinal direction of the middle window portion 21. In other words, in the vehicle body longitudinal direction of the middle window portion 21, the outer surface of the receiving portion 52C in the cross-sectional width direction of the column forms the boundary with the middle door pocket 211.

[0085] The pipe receiving member 53 is a columnar member extending in one direction with a constant cross section. The longitudinal length of the pipe receiving member 53 is approximately the same as the longitudinal length of the end post middle portion 43B. The pipe receiving member 53 is installed within the range of the middle window side panel portion 433B so that its longitudinal direction is parallel to the longitudinal direction of the end post 43.

[0086] The pipe receiving member 53 has a joint portion 53A and a receiving portion 53B. The receiving portion 53B is configured to be able to store a pipe that protects the wiring. FIG. 8 is a partial cross-sectional end view taken along the line YY in FIG. 7. In a cross section perpendicular to the longitudinal direction of the pipe receiving member 53, the joint portion 53A is formed in a relatively short, straight line. In addition, in a cross section perpendicular to the longitudinal direction of the pipe receiving member 53, the receiving portion 53B is formed to be curved at an obtuse angle outward from the tip of one side of the joint portion 53A. Furthermore, the receiving portion 53B is generally curved and bulged in a direction perpendicular to the joint portion 53A.

[0087] The pipe receiving member 53 is joined to the middle window side plate 433B on the surface of the joint 53A opposite to the side on which the receiving portion 53B is formed. When the pipe receiving member 53 is joined to the middle window side plate 433B, a space 53D is formed between the middle window side plate 433B and the receiving portion 53B, in which a pipe protecting the wiring is arranged along the column longitudinal direction. Furthermore, in the direction in which the receiving portion 53B bulges, a gap 53E is formed between the tip of the receiving portion 53B and the joint 53A. Therefore, when the pipe receiving member 53 is joined to the middle window side plate 433B, the tip side of the receiving portion 53B is open. The pipe receiving member 53 is joined to the middle window side plate 433B by welding.

[0088] Furthermore, in a cross section perpendicular to the longitudinal direction of the pipe receiving member 53, the overall length in the direction along the joint 53A is set to fit between the window frame receiving member 50 fixed to the end post 43 and the middle window-side flange portion 435B. In addition, in a cross section perpendicular to the longitudinal direction of the pipe receiving member 53, the overall length in the direction perpendicular to the joint 53A is slightly shorter than the length of the middle window-side flange portion 435B in the column cross-sectional width direction, but is roughly the same. Therefore, a space in which the pipe receiving member 53 is installed, and ultimately a space for piping, is formed in the column cross-sectional width direction of the end post middle portion 43B.

[0089] Next, a method for assembling the end post unit TU will be described. Fig. 9 is a partially exploded perspective view of the end post unit TU.

[0090] A floating nut 50C for fastening the middle window frame 44 is pre-attached to the surface of the main body 50A of the window frame support member 50 opposite the surface that joins with the middle base plate 431B. The floating nut 50C is attached near the boundary between the main body 50A and each insertion piece 50B. Each insertion piece 50B has three window frame support rivet insertion holes for inserting rivets 54, each at a position corresponding to the middle rivet insertion holes 442B formed in the middle base plate 431B. Each insertion piece 50B is then inserted into each middle insertion hole 441B. Rivets 54 are then driven into each of the communicating window frame support rivet insertion holes and each middle rivet insertion hole 442B to secure the window frame support member 50 to the door end post 43.

[0091] A floating nut 51C for fastening a lining plate (not shown) is pre-attached to the surface of the main body 51A of the lining plate receiving member 51 opposite the surface that joins with the lower base plate 431C. The floating nut 51C is attached to the main body 51A near the boundary with the insertion piece 51B. The insertion piece 51B also has three lining plate frame support rivet insertion holes for inserting rivets 55 at positions corresponding to the lower rivet insertion holes 442C formed in the lower base plate 431C. The insertion pieces 51B are then inserted into each of the lower insertion holes 441C. Rivets 55 are then driven into each of the communicating lining plate frame support rivet insertion holes and each of the lower rivet insertion holes 442C to secure the lining plate receiving member 51 to the door end post 43.

[0092] The main body 52A is brought into contact with the middle door-side flange 434B and the pair of legs 52B are brought into contact with the middle closing plate 436B from the outside of the end post 43 so that the gap 52D overlaps with the middle horizontal bone notch 440B formed on the lower side in the column cross-sectional width direction. Then, the side door receiving member 52 is fixed to the end post 43 by fastening the main body 52A and the middle door-side flange 434B with bolts 56 and fastening the pair of legs 52B and the middle closing plate 436B with bolts 56.

[0093] As described above, according to the railway vehicle system TS, the first vehicle 1 includes a side structure 1A3 in which the door end posts 43 that approach the side door 132 as the door opens are erected near the windows 102, 112, and 122, and the second vehicle 2 includes a side structure 2A3 in which the door end posts 43 that approach the side door 232 as the door opens are erected near the windows 202, 212, and 222, and the door end posts 43 associated with the side structure 1A3 are erected near the windows 102, 112, and 122 in the longitudinal direction of the car body. Door pockets 101, 111, and 121 capable of accommodating a side door 132 are formed on the opposite side of the windows 202, 212, and 122 from the end posts 43 of the side body structure 2A3, and door pockets 201, 211, and 221 capable of accommodating a side door 232 are formed on the opposite side of the windows 202, 212, and 222 in the longitudinal direction of the carbody from the end posts 43 of the side body structure 2A3. The longitudinal lengths of the door pockets 101, 111, and 121 and the longitudinal lengths of the door pockets 201, 211, and 221 are standardized. This standardizes the structure for mounting interior components such as equipment, wiring, and piping around the door pockets, facilitating the design and manufacture of the surrounding structure of the door pockets. Furthermore, according to the railway vehicle system TS, the structure of the end posts 43 of the side body structure 1A3 and the structure of the end posts 43 of the side body structure 2A3 are standardized. This further facilitates the design and manufacture of the surrounding structure of the door pockets.

[0094] The second car 2 also includes a door end post 43 located near the middle window frame 44. A pipe receiving member 53 is provided on the middle window frame 44 side of the door end post 43 to receive wiring or piping that runs along the longitudinal direction of the door end post 43. Therefore, the wiring and piping can be installed stably and reliably. As a result, the design and manufacture of the surrounding structure of the door pocket can be facilitated. Furthermore, the pipe receiving member 53 is provided over the entire length of the middle window frame 44 in the vertical direction. Therefore, the wiring or piping can be installed without creating cutouts in the middle window frame 44 or the door end post 43. As a result, the design and manufacture of the surrounding structure of the door pocket can be facilitated. Furthermore, the pipe receiving member 53 is open on the inside side of the car body in the width direction in a plan view. Therefore, even after installation, the wiring and piping can be easily inspected.

[0095] The second vehicle 2 also has a door end post 43 arranged near a middle window frame 44, the door end post 43 extending in the longitudinal direction of the door end post 43 and having a base plate portion 431 whose cross section perpendicular to the longitudinal direction of the door end post 43 is parallel to the longitudinal direction of the car body, a plate-shaped window frame support member 50 is fixed to the base plate portion 431 with rivets 54 so as to be parallel to the longitudinal direction of the car body, and the middle window frame 44 is fixed to the window frame support member 50. Therefore, in the work of attaching the window frame support member 50 to the door end post 43, a decrease in the strength of the door end post 43 is prevented, and the time required for the attachment work can be shortened by eliminating the need to correct distortion due to welding work or remove spatter after welding. Furthermore, the door end post 43 further has a window side panel portion 433 that extends in the longitudinal direction of the door end post 43 and is formed by bending at a substantially right angle from the end of the base plate portion 431 that is closer to the middle window frame 44 towards the outside of the vehicle in the width direction of the car body, and an intermediate insertion hole 441B is formed in the window side panel portion 433 near the base plate portion 431, and the window frame support member 50 has an insertion piece 50B that is inserted into the intermediate insertion hole 441B, and the insertion piece 50B is inserted into the intermediate insertion hole 441B and fixed to the base plate portion 431 by a rivet 54. Therefore, the distance between the middle window opening 21H and the door end post 43 can be shortened, and stress at the corner of the middle window opening 21H can be reduced. The window frame support member 50 also has a main body portion 50A extending in one direction, with the insertion piece 50B formed to protrude outward from one edge of the main body portion 50A, and a floating nut 50C provided on the main body portion 50A, with the middle window frame 44 being fixed to the window frame support member 50 via the floating nut 50C. Therefore, the door end post 43, more specifically the window side panel portion 433, and the window frame support member 50 are fixed in close proximity in the longitudinal direction of the vehicle body, which results in a shorter distance between the middle window opening 21H and the door end post 43 and reduces stress at the corners of the middle window opening 21H.

[0096] The second vehicle 2 also has a door end post 43 arranged near the middle window frame 44, and the door end post 43 is made of a single plate-shaped member and has a base plate portion 431 formed along the longitudinal direction of the door end post 43, an upper door side flange portion 434A, an upper window side flange portion 435A, a lower door side flange portion 434C, and a lower window side flange portion 435C, and in a cross section perpendicular to the longitudinal direction of the door end post 43, the base plate portion 431, the upper door side flange portion 434A, the upper window side flange portion 435A, the lower door side flange portion 434C, and the lower window side flange portion 435C are parallel to the longitudinal direction of the car body, and the base plate portion 431 is approximately perpendicular to the floor surface over the entire length of the base plate portion 431, and the upper door side flange portion 434C is parallel to the longitudinal direction of the car body. The flange portion 434A, the upper window side flange portion 435A, the lower door side flange portion 434C, and the lower window side flange portion 435C are positioned on the outer side of the vehicle in the vehicle width direction than the base plate portion 431, the upper door side flange portion 434A and the upper window side flange portion 435A are formed at the upper part of the door end post 43 in the longitudinal direction, and the lower door side flange portion 434C and the lower window side flange portion 435C are formed at the lower part of the door end post 43 in the longitudinal direction, and the distance in the vehicle width direction from the base plate portion 431 to the upper door side flange portion 434A and the upper window side flange portion 435A is different from the distance in the vehicle width direction from the base plate portion 431 to the lower door side flange portion 434C and the lower window side flange portion 435C. That is, in the door end post 43 made of a single plate-like member, the base plate portion 431, the upper door-side flange portion 434A, the upper window-side flange portion 435A, the lower door-side flange portion 434C, and the lower window-side flange portion 435C have a stepped structure in the vehicle body width direction. Therefore, the usability of the door end post 43 is improved.

[0097] Furthermore, the second vehicle 2 further includes a side outer panel 40 and a cross frame member 41 joined to the side outer panel 40 on the vehicle outer side of the door end post 43 in the vehicle width direction, and the cross frame member 41 includes an upper cross frame member 411 having a first length in the vehicle width direction and a lower cross frame member 413 having a second length in the vehicle width direction, and the upper cross frame member 411 is located above the door end post 43 in the longitudinal direction of the door end post 43, in other words, above the middle window opening 21H. The lower cross member 413 is positioned in a range corresponding to the lower part of the end post 43 in the longitudinal direction of the end post 43, in other words, below the middle window opening 21H, and the upper door-side flange portion 434A and the upper window-side flange portion 435A are joined to the interior surface of the upper cross member 411, while the lower door-side flange portion 434C and the lower window-side flange portion 435C are joined to the interior surface of the lower cross member 413. This makes it easy to join the end post 43 and the cross member 41. In the second vehicle 2, the door end post 43 further has a middle window-side flange portion 435B, and in a cross section perpendicular to the longitudinal direction of the door end post 43, the middle window-side flange portion 435B is parallel to the longitudinal direction of the car body, and is located further outward from the base plate portion 431 and on the middle window frame 44 side, and the distance from the base plate portion 431 to the middle window-side flange portion 435B is longer than the distance from the base plate portion 431 to the upper door-side flange portion 434A and upper window-side flange portion 435A in the car body width direction and the distance from the base plate portion 431 to the lower door-side flange portion 434C and lower window-side flange portion 435C in the car body width direction. Therefore, the usability of the door end post 43 is further improved.

[0098] It should be noted that this embodiment is merely an example and does not limit the present invention in any way. Naturally, therefore, the present invention can be modified in various ways without departing from the spirit of the present invention. Therefore, modifications of this embodiment will be described. It should be noted that the modifications described below can also be combined as appropriate.

[0099] The railway vehicle system TS is composed of a first vehicle 1 and a second vehicle 2, but the railway vehicle system TS may also be composed of a different vehicle and the first vehicle 1 and the second vehicle 2. In other words, the railway vehicle system TS may be composed of three or more different vehicles. Furthermore, the railway vehicle system TS may be composed of two or more different vehicle types operated by a single railway company.

[0100] The window frame support member 50 is a columnar member extending in one direction, but may be configured with a length that is extremely short compared to the vertical length of the middle window frame 44. Furthermore, multiple such short window frame support members 50 may be installed at predetermined intervals along the longitudinal direction of the end post 43. Furthermore, the cross-sectional shape of the window frame support member 50 may be changed as appropriate as long as the piping can be accommodated in the cross section. For example, the cross-sectional shape of the window frame support member 50 may be hook-shaped. Alternatively, the cross-sectional shape of the window frame support member 50 may be U-shaped to close the opening.

[0101] The pipe receiving member 53 receives pipes that protect the wiring, but may also receive the wiring directly. Furthermore, the body structure 1A and the body structure 2A are configured by being divided into multiple sections in the longitudinal direction of the car body, but the division allocation of either or both of the body structure 1A and the body structure 2A may be modified as appropriate. Furthermore, either or both of the body structure 1A and the body structure 2A may not be configured by being divided into multiple sections in the longitudinal direction of the car body. Furthermore, for example, members other than the window frame receiving member 50, the interior panel receiving member 51, the side door receiving member 52, and the pipe receiving member 53, such as members for fixing seats, may be attached to the door end post 43.
