Description

Technical Field

[0001] The present invention relates to a railway vehicle including a partition panel that partitions a passage of an entrance / exit platform and houses in-vehicle equipment.

Background Art

[0002] Conventionally, a railway vehicle has been disclosed that includes a partition panel that partitions a passage of an entrance / exit platform (deck) and houses in-vehicle equipment (see Patent Document 1). The partition panel (referred to as "opening / closing door 1" in Patent Document 1) according to Patent Document 1 includes a housing having an opening, and a door attached to the opening. The door is rotatably supported by the housing via a hinge having a rotation axis parallel to the vehicle height direction.

[0003] Incidentally, the door constituting the partition panel at the entrance / exit platform may be disposed in the vicinity of the side entrance / exit portion. In this case, for example, as shown in FIG. 5, a side entrance / exit pillar 92 for fixing the partition panel 90 is erected from the floor in the vicinity of the door 91 constituting the partition panel 90, and a pillar base 94 for hiding the side entrance / exit pillar 92 and improving the appearance is installed on the passage side of the side entrance / exit pillar 92 and in the vicinity of the boarding / alighting door 93.

[0004] The pillar base 94 is disposed along the extending direction (vehicle width direction) of the door 91 when the door 91 is closed in plan view. From the viewpoint of aesthetics, the joint gap between the pillar base 94 and the door 91 is set to 5 to 10 mm, and the gap between the pillar base 94 and the door 91 is made as narrow as possible.

Summary of the Invention

Problems to be Solved by the Invention

[0006] When the applicant installed the partition panel 90, the installation order of the column cover 94 and the door 91 was that the door 91 was installed first, followed by the column cover 94. However, since the column cover 94 is sandwiched between the passenger door 93 and the door 91 installed at the side entrance, the installation of the column cover 94 was difficult when the gap between the column cover 94 and the door 91 was 5 to 10 mm.

[0007] The present invention was made to solve the aforementioned problems, and aims to provide a railway vehicle that can shorten the installation time of column covers while suppressing a deterioration in the appearance around the doors that constitute the partition panels on the entrance / exit platform. [Means for solving the problem]

[0008] To achieve the above objective, a railway vehicle according to one aspect of the present invention has the following features.

[0009] (1) Equipped with partition panels that demarcate the passageway of the entrance / exit platform and house the interior equipment, The partition panel comprises a housing having an opening and a door attached to the opening. The aforementioned door is rotatably supported in the housing via a hinge having a pivot axis parallel to the height direction of the vehicle body, in a railway vehicle. The rotation axis is formed at one end of the door in a plan view, The door comprises a plate-shaped main body and the passage from one end of the main body in a plan view. It has a covering portion that extends on the opposite side of the road, The main body is joined to the hinge on the side opposite to the passage, The covering portion is characterized in that it faces the hinge in the extending direction of the main body portion in a plan view and covers the hinge. According to the embodiment described in (1) above, the covering portion formed extending from one end of the plate-shaped main body in a plan view toward the opposite side of the passage faces the hinge joined to the main body on the opposite side of the passage, and covers the hinge, so that the part of the main body including the hinge that connects to the opposite side of the passage is shielded. Therefore, a deterioration in the appearance around the door can be suppressed. Furthermore, since the part of the main body including the hinge that connects to the opposite side of the passage is shielded in this way, the column cover can be installed at a certain distance from the direction of extension of the door when it is closed. As a result, the installation time of the column cover can be shortened.

[0010] (2) In the railway vehicle described in (1), the covering portion may be formed in a substantially arc shape with respect to the axis of rotation in a plan view. In the embodiment described in (2) above, the covering portion that is exposed to the outside and is conspicuous is formed in a substantially arc shape, which further reduces the deterioration of the appearance around the door. (3) In the railway vehicle described in (1) or (2), a column member extending along the height direction of the vehicle body is installed, The cross-section of the column member perpendicular to the vehicle body height direction has a plate-shaped base portion formed along the extending direction of the door when closed, a plate-shaped intermediate plate portion formed substantially perpendicularly from the door-side end of the base portion toward the opposite side of the passage, and a plate-shaped door receiving plate portion formed substantially perpendicularly from the end of the intermediate plate portion opposite to the passage toward the opposite side of the base portion. The intermediate plate portion is positioned opposite the covering portion in a distance in the extending direction of the door when the door is closed. The door receiving plate portion may be positioned opposite the covering portion at a distance in a direction perpendicular to the extending direction of the door when the door is closed. The embodiment described in (3) above makes it possible to suppress the deterioration of the appearance between the column casing and the door. (4) In the railway vehicle described in (3), when the door is closed, the distance between the intermediate plate portion and the covering portion in the extending direction of the door is 25 mm or more, and may be 30 mm or less. If the distance between the intermediate plate portion and the covering portion in the extending direction of the door when the door is closed is too long, the aesthetic appearance around the door will be reduced, while if it is too short, it will be difficult to install the column cover. Therefore, the embodiment described in (4) above makes it possible to effectively reduce the appearance around the door while shortening the installation time of the column cover. [Effects of the Invention]

[0011] According to the present invention, it is possible to reduce the installation time of the column cover while suppressing the deterioration of the appearance around the door that constitutes the partition panel in the entrance / exit platform. [Brief explanation of the drawing]

[0012] [Figure 1] This is a schematic side view of the vehicle as seen from the left side. [Figure 2] This is a schematic plan view showing the interior of the front entrance platform. [Figure 3] This is a view along the arrow AA in Figure 2. [Figure 4A] Figure 3 is a cross-sectional end view of BB. [Figure 4B] Figure 3 is a cross-sectional end view of CC. [Figure 5] This is an explanatory diagram illustrating the conventional challenges. [Modes for carrying out the invention]

[0013] <First Embodiment> Next, a railway vehicle according to the first embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a schematic side view of a railway vehicle 1 (hereinafter referred to as "vehicle 1") according to the first embodiment of the present invention. For the sake of convenience, it is assumed in Fig. 1 that the vehicle 1 travels to the left. With respect to the longitudinal direction of the car body 10 (the longitudinal direction of the car body) constituting the vehicle 1, the left side where the vehicle 1 travels is referred to as the "front side", and the right side opposite to the left side where it travels is referred to as the "rear side" for explanation. Also, with respect to the width direction of the car body 10 (the width direction of the car body), the right side and the left side in the situation facing from the rear side to the front side in the longitudinal direction of the car body are referred to as the "right side" and the "left side", respectively. Therefore, Fig. 1 is a schematic side view of the vehicle 1 as viewed from the left side.

[0014] The vehicle 1 will be described. The vehicle 1 consists of a premium vehicle. The structure 10A forming the framework of the car body 10 of the vehicle 1 includes a platform frame 11 forming the floor surface of the car body 10, a pair of gable structures 12 erected at both ends of the platform frame 11 in the longitudinal direction of the car body, a pair of side structures 13 erected at both ends of the platform frame 11 in the width direction of the car body, and a roof structure 14 arranged at the upper ends of the pair of gable structures 12 and the pair of side structures 13 to form the roof of the car body 10.

[0015] The car body 10 is divided into a passenger compartment R1, a front entrance platform R2, and a rear entrance platform R3. It is divided into the front entrance platform R2, the passenger compartment R1, and the rear entrance platform R3 in order from the front along the longitudinal direction of the car body. The front entrance platform R2 and the passenger compartment R1 are partitioned by a front partition side wall 20. The passenger compartment R1 and the rear entrance platform R3 are partitioned by a rear partition side wall 21. Note that the vehicle 1 may be composed of the passenger compartment R1 and the rear entrance platform R3, or may be composed of the passenger compartment R1 and the front entrance platform R2.

[0016] One side entrance portion 13h is provided in the portion of each side structure 13 that constitutes the front entrance platform R2 and the portion that constitutes the rear entrance platform R3. The side entrance portion 13h is formed in a vertically long rectangular shape. A boarding and alighting door 22 that can be opened and closed along the longitudinal direction of the car body is installed in the side entrance portion 13h.

[0017] Next, the interior of the front entrance platform R2 will be described. Fig. 2 is a schematic plan view schematically showing the interior portion of the front entrance platform R2.

[0018] A roughly cross-shaped passageway 30 is formed on the front entrance platform R2 in plan view. Hereinafter, the portion of the passageway 30 parallel to the longitudinal direction of the vehicle body will be referred to as the "first passageway 30A," and the portion parallel to the width direction of the vehicle body will be referred to as the "second passageway 30B." The first passageway 30A is formed in a straight line in the center of the front entrance platform R2 in the width direction of the vehicle body. The second passageway 30B is formed in a straight line towards the rear of the front entrance platform R2.

[0019] Furthermore, the plan view shape of the passage 30 formed on the front entrance platform R2 is not limited to a roughly cross shape and may be changed as appropriate. For example, the plan view shape of the passage 30 may be roughly T-shaped or roughly L-shaped. Moreover, the plan view shape of the passage 30 may be straight, curved, or wavy, for example. If the plan view shape of the passage 30 is roughly straight, the passage 30 may be formed on one side in the vehicle width direction of the front entrance platform R2, or it may be formed in the center in the vehicle width direction of the front entrance platform R2.

[0020] The passageway 30 is partitioned by a floor panel 31, a partition panel 32, and a ceiling panel 33 (see Figure 3). The floor panel 31 is supported by a base frame 11 located directly below it, and the ceiling panel 33 is supported by a roof structure 14 located directly above it (see Figure 3). The partition panel 32 is erected approximately perpendicular to the floor panel 31 and is positioned between the floor panel 31 and the ceiling panel 33 (see Figure 3).

[0021] The partition panel 32 includes 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 The front right partition panel 32B is located in front of and to the left 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.

[0022] The front left partition panel 32A, the front right partition panel 32B, the rear left partition panel 32C, and the rear right partition panel 32D each include a straight section (first straight section) that faces the first passage 30A in the vehicle width direction, in other words, a straight section (second straight section) that faces the second passage 30B in the vehicle longitudinal direction, in other words, a straight section that defines the second passage 30B, and a corner section that connects the first straight section and the second straight section at a roughly right angle and in an arc shape.

[0023] On the side of the front left partition panel 32A opposite the passage 30, a men's toilet room R21, a unisex toilet room R22, and a washroom R23 are installed in order from front to rear. Furthermore, on the side of the front left partition panel 32A opposite the passage 30, and behind the washroom R23, a distribution panel M is housed. On the side of the front right partition panel 32B opposite the passage 30, the first machine room R24 and the second machine room R25 are installed in order from front to rear.

[0024] Next, the front left partition panel 32A will be described. The front left partition panel 32A comprises a housing 40 erected vertically on the floor 31 and a door 41 attached to the housing 40. As shown in Figure 2, the door 41 is located in the portion of the front left partition panel 32A facing the second passage 30B (the second straight section). The distribution board M is housed on the side of the door 41 opposite the second passage 30B. In other words, the door 41 is installed relative to the distribution board M. In the following, the side of the door 41 facing the second passage 30B (the rear side of the door 41) may be referred to as the "front side," and the side of the door 41 opposite the second passage 30B (the front side of the door 41) may be referred to as the "rear side."

[0025] Furthermore, the door 41 is positioned on one side of the front left partition panel 32A in the direction of extension in a plan view, in other words, at the end closer to the side structure 13 in the vehicle width direction. A pillar cover 42 is installed between the door 41 and the side structure 13. The door 41 and the pillar cover 42 are in close proximity in the vehicle width direction.

[0026] Figure 3 is a view taken along arrow AA in Figure 2. Figure 4A is a cross-sectional end view of BB in Figure 3, and Figure 4B is a cross-sectional end view of CC in Figure 3.

[0027] In the portion of the enclosure 40 facing the second passage 30B (the second straight section), a vertically elongated, roughly rectangular opening 40A is formed when viewed from the front. A door 41 is attached to the opening 40A.

[0028] The door 41 is shaped as a roughly elongated rectangle when viewed from the front, and has a main body portion 411 which makes up the majority of the door except for the left end, and a covering portion 412 which makes up the left end. The door 41 is rotatably supported on the vertical frame 401 which makes up the housing 40 via a hinge 43 which has a pivot axis X1.

[0029] The vertical frame 401 is made of steel with an L-shaped cross-section, with the vehicle height direction as its axial direction, and extends in the vehicle height direction. The vertical frame 401 forms the end on the same side as the door 41 in the extending direction in a plan view of the housing 40, and partitions the left side of the opening 40A. The left end of the main body 411 is joined to the front surface of the vertical frame 401 via a hinge 43. The vertical frame 401 is fixed to the side entrance column 35, which will be described later, via a receiving member 46.

[0030] Multiple hinges 43 (five in the first embodiment) are arranged side by side at approximately equal intervals in the height direction of the vehicle body. Each hinge 43 is fixed to the back of the main body 411 via a door-side fixing device 44 and to the front of the vertical frame 401 via a housing-side fixing device 45. The shape and position of each hinge 43 are configured so that when the door 41 rotates, the tip 412AT of the covering portion 412 (described later) does not interfere with the hinge 43 and the main body 451 (described later).

[0031] The structure of the door-side fixing device 44 can be appropriately set within the range that allows the door 41 and the hinge 43 to be fixed. The door-side fixing device 44 has a main body 441 made of L-shaped steel, bolts 442 and 443, and a spacer 444. The main body 441 and the main body part 411 are fixed by bolt 442, and the main body 441 and the hinge 43 are fixed via the spacer 444 by bolt 443.

[0032] Furthermore, the structure of the housing-side fixing device 45 can be appropriately set within the range that allows the housing 40 and the hinge 43 to be fixed. The housing-side fixing device 45 has a main body 451 made of steel material with a roughly U-shaped cross-section, bolts 452, 453, and spacers 454, 455. The main body 451 and the vertical frame 401 are fixed to each other via spacers 454 by bolts 452, and the main body 451 and the hinge 43 are fixed to each other via spacers 455 by bolts 453.

[0033] The pivot axis X1 of the hinge 43 is parallel to the height direction of the vehicle body. The door 41 can rotate clockwise and counterclockwise within the range from the position shown by the solid line in Figure 4A to the position shown by the dashed line, which is 90 degrees clockwise in a plan view around the pivot axis X1. The opening 40A is opened and closed by the rotation of the door 41.

[0034] Note that the door 41 shown in Figures 3, 4A, and 4B is in a state where the opening 40A is completely closed. Hereafter, the position of the door 41 relative to the housing 40 shown in Figures 3, 4A, and 4B will be referred to as the "fully closed position". Also, the position of the door 41 relative to the housing 40, which is 90 degrees clockwise in a plan view from the fully closed position shown in Figure 4A, will be referred to as the "fully open position".

[0035] The column cover 42 extends along the vehicle height direction overall. The cross-sectional shape of the column cover 42 perpendicular to the vehicle height direction (column cover cross-sectional shape) can be broadly divided into three types along the vehicle height direction. That is, the column cover cross-sectional shape differs at the top, bottom, and center. Hereinafter, the top, bottom, and center of the column cover 42 will be referred to as "upper column cover 42U," "center column cover 42C," and "lower column cover 42D," respectively.

[0036] The upper part 42U of the column cover has, in a cross section perpendicular to the vehicle body height direction, a base plate portion 421 that is generally plate-shaped and parallel to the vehicle body width direction, an intermediate plate portion 422 that is generally plate-shaped and parallel to the vehicle body longitudinal direction, perpendicular to the right end of the base plate portion 421 toward the rear side, and a door receiving plate portion 423 that is generally plate-shaped and parallel to the vehicle body width direction, perpendicular to the right end of the intermediate plate portion 422 (see Figure 4A). The relative lengths of the extension directions of each part are as follows: extension direction length of base plate portion 421 > extension direction length of door receiving plate portion 423 > extension direction length of intermediate plate portion 422.

[0037] The base plate portion 421 is formed on the extending direction of the main body portion 411 when the door 41 is completely closed. The intermediate plate portion 422 is formed to the left of the covering portion 412 (towards the vehicle body width direction side structure 13) when the door 41 is completely closed. The door receiving plate portion 423 is formed on the rear side of the hinge 43 and the covering portion 412 in the longitudinal direction of the vehicle body, and spans the outside of the door 41, the covering portion 412 and the main body portion 411 when the door 41 is completely closed in the vehicle body width direction. In this embodiment, the right end of the door receiving plate portion 423 in the vehicle body width direction (inside the vehicle body) is further bent at approximately a right angle to provide an end rise portion 4231, thereby maintaining the flatness of the door receiving plate portion 423 and suppressing a decrease in appearance. Furthermore, the rigidity is increased by the end rise portion 4231. Therefore, even if the column cover 42 is slightly deformed due to temperature changes or contact with passengers, the original shape is maintained in the narrow gap between the hinge 43 and the door receiving plate 423, preventing contact between the opposing hinges 43 and between the covering portion 412 and the door receiving plate 423.

[0038] The central column cover 42C has, in a cross section perpendicular to the vehicle body height direction, a plate-shaped base portion 421 that is parallel to the vehicle body width direction and is generally plate-shaped, a door receiving plate portion 423 that is parallel to the vehicle body width direction and is generally plate-shaped, and an intermediate projection portion 424 with a roughly U-shaped cross section that connects the right end of the base portion 421 and the left end of the door receiving plate portion 423 (see Figure 4B).

[0039] The base plate portion 421 relating to the center 42C of the column cover is integrally continuous with the base plate portion 421 relating to the upper 42U of the column cover. However, although the left end of the base plate portion 421 relating to the center 42C of the column cover and the left end of the base plate portion 421 relating to the upper 42U of the column cover are aligned in the vehicle height direction, the length of the base plate portion 421 relating to the center 42C of the column cover in the vehicle width direction is shorter than the length of the base plate portion 421 relating to the upper 42U of the column cover in the vehicle width direction.

[0040] The door receiving plate portion 423 relating to the center 42C of the column casing is integrally continuous with the door receiving plate portion 423 relating to the upper side 42U of the column casing. However, although the right end of the door receiving plate portion 423 relating to the center 42C of the column casing and the right end of the door receiving plate portion 423 relating to the upper side 42U of the column casing are aligned in the vehicle body height direction, the length of the door receiving plate portion 423 relating to the center 42C of the column casing in the vehicle body width direction is shorter than the length of the door receiving plate portion 423 relating to the upper side 42U of the column casing in the vehicle body width direction.

[0041] Furthermore, the door receiving plate portion 423 related to the center 42C of the column casing is offset from the outside of the door 41 in the vehicle width direction when the door 41 is completely closed, with respect to the longitudinal direction of the vehicle body, and is formed spanning the covering portion 412 and the main body portion 411 of the door 41 when the door 41 is completely closed.

[0042] The intermediate projection 424 related to the center 42C of the column cover is formed to protrude generally toward the rear side, and in a cross section perpendicular to the height direction of the vehicle body, it has a flat plate portion 424A that is parallel to the width direction of the vehicle body and is generally plate-shaped, a left-side connecting portion 424B that connects the flat plate portion 424A and the base plate portion 421, and a right-side connecting portion 424C that connects the flat plate portion 424A and the door receiving plate portion 423.

[0043] The flat plate portion 424A is formed on the rear side of the door receiving plate portion 423 in the longitudinal direction of the vehicle body. The left connecting portion 424B smoothly connects the left end of the flat plate portion 424A and the right end of the base plate portion 421, and is formed in a roughly arc shape that protrudes approximately to the left overall. The right connecting portion 424C smoothly connects the right end of the flat plate portion 424A and the left end of the door receiving plate portion 423, and is formed in a roughly arc shape that protrudes approximately to the right overall.

[0044] Although not shown in the figures, the lower part of the column cover 42D, in a cross section perpendicular to the vehicle height direction, generally has a base plate portion 421, an intermediate plate portion 422, and a door receiving plate portion 423, similar to the upper part of the column cover 42U (see Figure 3). However, the length of the base plate portion 421 in the vehicle width direction becomes shorter as it extends downwards. Also, the position of the left end of the base plate portion 421 moves to the right as it extends downwards.

[0045] Furthermore, a handrail 34 is installed inside the column cover 42. The handrail 34 extends along the height direction of the vehicle body. The handrail 34 is positioned on the front side of the flat plate section 424A in the longitudinal direction of the vehicle body, is exposed at the center 42C of the column cover, and is covered by the lower part 42D of the column cover.

[0046] On the rear side of the column cover 42 in the longitudinal direction of the vehicle body, more specifically on the rear side of the flat plate portion 424A in the longitudinal direction of the vehicle body, a side entrance column 35 is erected perpendicularly to the floor 30, with its axial direction parallel to the vehicle body height direction. A buffer member 36 is tightly fitted between the side entrance column 35 and the flat plate portion 424A. It is intervening in that state.

[0047] A passenger door 22 is installed at the side entrance 13h. Furthermore, outer door pocket pillars 37A are positioned on the outer side of both outer edges of the side entrance 13h in the longitudinal direction of the vehicle body, and inner door pocket pillars 37B are positioned on the inner side. The outer door pocket pillars 37A and inner door pocket pillars 37B are erected approximately perpendicularly to the underframe 11. The passenger door 22 is slidable between the outer door pocket pillars 37A and inner door pocket pillars 37B along the longitudinal direction of the vehicle body.

[0048] The door pocket pillar 37B and the pillar cover 42 are installed separately in the longitudinal direction of the vehicle body. The door pocket pillar 37B is positioned behind the pillar cover 42. Furthermore, the right end of the door pocket pillar 37B and the left end of the base portion 421 of the pillar cover 42 are aligned at approximately the same position along the longitudinal direction of the vehicle body. The pillar cover 42 is fixed to the pillar cover receiving member 38, which is fixed to the door pocket pillar 37B, via a buffer member 39 at the left end of the back surface of the base portion 421. The buffer member 39 is bonded to both the pillar cover receiving member 38 and the base portion 421.

[0049] Next, the covering portion 412 and the gap S1 between the door 41 and the column frame 42 will be described. The covering portion 412 is formed at the left end of the door 41, in other words, at the end of the door 41 that is closer to the column frame 42 and the side structure 13 in the direction of extension when viewed from above. In the first embodiment, the covering portion 412 is the portion located to the left of a plane that includes a straight line parallel to the longitudinal direction of the vehicle body passing through the rotation axis X1 of the door 41 and is parallel to the longitudinal direction of the vehicle body. The covering portion 412 is formed continuously from the left end of the main body portion 411, which is vertically elongated rectangular in front view and is generally plate-like. For convenience, it is separated from the main body portion 411, but the covering portion 412 and the main body portion 411 are molded integrally.

[0050] The covering portion 412 is formed to extend to the rear side in the longitudinal direction of the vehicle body along the entire length of the main body portion 411 in the height direction of the vehicle body. In a plan view, the covering portion 412 is housed within a rectangular area with the intermediate plate portion 422 as the short side and the door receiving plate portion 423 as the long side. When the door 41 is completely closed, the covering portion 412 is generally positioned to face the intermediate plate portion 422 at a distance in the width direction of the vehicle body, and to face the door receiving plate portion 423 at a distance in the longitudinal direction of the vehicle body. That is, a gap S1 is formed between the covering portion 412, the intermediate plate portion 422, and the door receiving plate portion 423 in the width direction of the vehicle body.

[0051] Furthermore, the tip of the covering portion 412 extends between the hinge 43 and the door receiving plate portion 423 in the longitudinal direction of the vehicle body. Therefore, in the width direction of the vehicle body, the covering portion 412 almost completely covers the space between the outside and inside of the door 41, including the hinge 43.

[0052] The plan view shape of the covering portion 412 is an arc shape with the rotation axis X1 as its center and projecting toward the pillar cover 42 side (left side). When the door 41 is completely closed, the plan view shape of the covering portion 412 is approximately symmetrical with respect to a straight line parallel to the vehicle width direction passing through the rotation axis X1.

[0053] Furthermore, the front side of the main body portion 411 is formed flat, and in a plan view, the front surface (outer surface of the main body portion) 411A of the main body portion 411 is parallel to the width direction of the vehicle body and is formed continuously with the radially outer surface (outer surface of the covering portion) 412A of the covering portion 412.

[0054] The position of the boundary K1 between the outer surface 411A of the main body and the outer surface 412A of the covering is approximately the same as the position of the rotation axis X1 in the vehicle body width direction. The outer surface 412A of the covering is formed from the boundary K1 in a clockwise arc shape with the rotation axis X1 as the center and the distance between the rotation axis X1 and the boundary K1 in the longitudinal direction of the vehicle body as the radius r1.

[0055] The position of the tip 412AT of the outer surface 412A of the covering portion in the vehicle width direction is closer to the pillar cover 42 than the position of the rotation axis X1 in the vehicle width direction. In detail, when the door 41 is completely closed, at the center With a rotation axis X1 as the vertex, the angle between the half-line connecting the vertex and the tip 412AT of the outer surface 412A of the covering portion and the half-line passing through the rotation axis X1 and parallel to the width direction of the vehicle body is approximately 60 degrees. On the other hand, when the door 41 is completely closed, with the rotation axis X1 as the vertex, the angle between the half-line connecting the vertex and the boundary K1 which is the base end of the outer surface 412A of the covering portion and the straight line passing through the rotation axis X1 and parallel to the width direction of the vehicle body is approximately 90 degrees.

[0056] For the arc-shaped outer surface 412A of the covering portion, the tangent line at the intersection P1 of a straight line parallel to the vehicle width direction passing through the rotation axis X1 and the outer surface 412A of the covering portion is parallel to the longitudinal direction of the vehicle body. Therefore, from the fully closed position to the fully open position, the absolute position of the door 41 with respect to the intersection P1 when the door 41 is completely closed is always closest to the pillar cover 42 in the vehicle width direction. That is, from the fully closed position to the fully open position, the gap width H1 between the door 41 (covering portion 412) and the pillar cover 42 in the vehicle width direction remains constant. In the first embodiment, the gap width H1 is set to 28 mm. However, the gap width H1 is not limited to 28 mm, but if the gap width H1 is too wide, the aesthetic appeal will decrease, and if the gap width H1 is too narrow, it may interfere with the installation work of the pillar cover 42, so the gap width H1 is preferably 20 mm to 35 mm. Furthermore, the gap width H1 is preferably 25mm to 30mm.

[0057] When the door 41 is completely closed, the tip 412AT of the outer surface 412A of the covering portion is away from the door receiving plate portion 423 in the longitudinal direction of the vehicle body, but is the part of the outer surface 412A of the covering portion that is closest to the door receiving plate portion 423. Furthermore, the distance between the tip 412AT of the outer surface 412A of the covering portion and the door receiving plate portion 423 in the longitudinal direction of the vehicle body when the door 41 is completely closed is set to be longer than the shortest distance between the outer surface 412A of the covering portion and the door receiving plate portion 423 in the longitudinal direction of the vehicle body when the door 41 is in the fully open position. This is to prevent the covering portion 412 from contacting the door receiving plate portion 423 and causing interference with the opening and closing of the door 41.

[0058] When the door 41 rotates from a completely closed position, the outer surface 412A of the covering rotates along a trajectory that follows the arc shape it had when completely closed, in a plan view. Therefore, as the door 41 moves from the fully closed position to the fully open position, the distance between the outer surface 412A of the covering and the door receiving plate 423 in the longitudinal direction of the vehicle body becomes even shorter than when the door 41 is completely closed. Specifically, the distance between the outer surface 412A of the covering and the door receiving plate 423 in the longitudinal direction of the vehicle body is shortest on a straight line parallel to the longitudinal direction of the vehicle body passing through the rotation axis X1. After the tip 412AT of the outer surface 412A of the covering reaches this straight line, the shortest distance between the outer surface 412A of the covering and the door receiving plate 423 in the longitudinal direction of the vehicle body remains constant.

[0059] Furthermore, when the door 41 is completely closed, the door receiving plate portion 423 extends to the right of the straight line connecting the boundary K2 between the outer surface 421A of the base plate portion 421 and the outer surface 422A of the intermediate plate portion 422, and the tip 412AT of the outer surface 412A of the covering portion. Therefore, even when the door 41, which has the largest distance in the longitudinal direction of the vehicle body between the tip 412AT of the outer surface 412A of the covering portion and the door receiving plate portion 423, is completely closed, the space between the door 41 and the pillar cover 42 is shielded, preventing its rear side from being seen.

[0060] As described above, vehicle 1 has (1) a partition panel 32 that demarcates the passage 30 of the front entrance platform R2 and houses the interior equipment, and the front left partition panel 32A of the partition panel 32 has a housing 40 having an opening 40A and a door 41 attached to the opening 40A, and the door 41 is rotatably supported on the vertical frame 401 of the housing 40 via a hinge 43 having a rotation axis X1 parallel to the height direction of the vehicle body, and the rotation axis X1 is formed at the end of one side (left side in the width direction of the vehicle body) of the door 41 in a plan view. Furthermore, in vehicle 1, the door 41 has a plate-shaped main body portion 411 and a covering portion 412 that is formed extending from the tip of one side (left side in the width direction of the vehicle body) of the main body portion 411 in a plan view to the rear side (opposite side from the second passage 30B), and the main body portion 41 Part 1 is joined to the hinge 43 on the rear side (opposite side of the second passage 30B), and the covering part 412 faces the hinge 43 in the extending direction of the main body part 411 in a plan view, and covers the hinge 43. Here, the covering part 412, which is formed by extending from the tip of one side (left side in the vehicle width direction) of the plate-shaped main body part 411 in a plan view to the rear side (opposite side of the second passage 30B), faces the hinge 43 which is joined to the main body part 411 on the rear side (opposite side of the second passage 30B), and covers the hinge 43, so the part of the main body part 411 that connects to the rear side (opposite side of the second passage 30B), including the hinge 43, is shielded. Therefore, the deterioration of the appearance around the door 41 can be suppressed. Furthermore, since the portion of the main body 411 including the hinge 43 that connects to the rear side (opposite side of the second passage 30B) is shielded in this way, the column cover 42 can be installed at a certain distance from the extending direction of the door 41 when it is closed. As a result, even when the column cover 42 is installed behind the door 41, the installation time for the column cover 42 can be reduced.

[0061] Furthermore, according to vehicle 1, the covering portion 412 is formed in a substantially arc shape centered on the rotation axis X1 in a plan view. Since the covering portion 412, which is exposed to the outside and can be conspicuous, is formed in an arc shape, the deterioration of the appearance around the door 41 can be further suppressed.

[0062] Furthermore, according to vehicle 1, a column cover 42 (column member) extending along the height direction of the vehicle body is installed, and the cross section of the column cover 42 (column member) perpendicular to the height direction of the vehicle body has a plate-shaped base plate portion 421 formed along the extending direction of the door 42 when it is closed, a plate-shaped intermediate plate portion 422 formed at approximately a right angle from the end of the base plate portion 421 on the door 41 side toward the rear side (opposite side of the second passage 30B), and a plate-shaped door receiving plate portion 423 formed at approximately a right angle from the end of the intermediate plate portion 422 on the rear side (opposite side of the second passage 30B) toward the opposite side of the base plate portion 421, the intermediate plate portion 422 facing the covering portion 412 at a distance in the extending direction of the door 41 when the door 41 is closed, and the door receiving plate portion 423 facing the covering portion 412 at a distance in a direction perpendicular to the extending direction of the door 41 when the door 41 is closed. Therefore, the deterioration in appearance between the column cover 42 (column member) and the door 41 can be suppressed. Also, if the gap width H1 (separation distance) between the intermediate plate portion 422 and the covering portion 412 in the extending direction of the door 41 when the door 41 is closed is too long, the aesthetic appearance around the door 41 will deteriorate, while if it is too short, it will interfere with the installation of the column cover 42 (column member). Therefore, according to vehicle 1, the gap width H1 (separation distance) between the intermediate plate portion 422 and the covering portion 412 in the extending direction of the door 41 when the door 41 is closed is 25 mm or more and 30 mm or less, so that the deterioration in appearance between the door 41 and the column cover 42 (column member) can be suppressed effectively, while shortening the installation time of the column cover 42 (column member).

[0063] <Example of changes> Next, we will describe some examples of modifications to the vehicle 1 according to the first embodiment. The first embodiment described above can be modified as appropriate without altering the essence of the present invention.

[0064] The installation position of the door 41 may be changed as appropriate. For example, the door 41 may be placed at the opposite end (longitudinal direction of the vehicle body) in the direction of extension of the front left partition panel 32A in a plan view. Also, similar to the installation on the front left partition panel 32A, the door 41 may be installed on partition panels 32 located at other locations on the front entrance platform R2 (front right partition panel 32B, rear left partition panel 32C, rear right partition panel 32D).

[0065] The plan view shape of the covering portion 412 may also be changed as appropriate. For example, the tip of the covering portion 412 may be further extended along an arc shape compared to the first embodiment, or it may be shortened. Alternatively, the plan view shape of the covering portion 412 may be a shape that is not an arc shape centered on the rotation axis X1. However, in this case, it is preferable that the covering portion 412 does not come into contact with the door receiving plate portion 423 when the door 41 rotates between the fully closed position and the fully open position.

[0066] This embodiment is merely illustrative and does not limit the present invention in any way. Therefore, the present invention can naturally be modified in various ways without departing from its essence. [Explanation of Symbols]
