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 according to Patent Document 1 (referred to as "opening / closing door 1" in 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 capping 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 capping 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 capping 94 and the door 91 is set to 5 to 10 mm, and the gap between the pillar capping 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 installs the partition panel 90, the installation order of the pillar base 94 and the door 91 is that the door 91 is installed first and the pillar base 94 is installed later. However, since the pillar base 94 is sandwiched between the boarding and alighting door 93 installed at the side entrance and exit and the door 91, it was difficult to install the pillar base 94 under the condition that the joint gap with the door 91 was 5 to 10 mm.

[0007] The present invention has been made to solve such problems, and an object thereof is to provide a railway vehicle capable of shortening the installation work time of a pillar base while suppressing a decrease in the appearance around a door constituting a partition panel in a vestibule.

Means for Solving the Problems

[0008] In order to achieve the above object, a railway vehicle according to an aspect of the present invention has the following features.

[0009] (1) It is provided with a partition panel that partitions the passage in the vestibule and houses the in-vehicle equipment. The partition panel includes a housing having an opening and a door attached to the opening. The door is a railway vehicle rotatably supported by the housing via a hinge having a rotation axis parallel to the vehicle body height direction. The rotation axis is formed at one end of the door in a plan view. The door has a plate-shaped main body portion and a covering portion formed to extend from the tip of the one side of the main body portion in a plan view to the side opposite to the passage. The main body portion is joined to the hinge on the side opposite to the passage. The covering portion faces the hinge in the extending direction of the main body portion in a plan view and covers the hinge. It is characterized in that. According to the aspect described in (1) above, the covering portion formed to extend from one tip on one side in the plan view of the plate-shaped main body portion to the side opposite to the passage faces the hinge joined on the side opposite to the main body portion and the passage, and covers the hinge. Therefore, the portion connecting to the side opposite to the passage of the main body portion including the hinge is shielded. Accordingly, it is possible to suppress a decrease in the appearance around the door. Furthermore, since the portion connecting to the side opposite to the passage of the main body portion including the hinge is shielded in this way, it is possible to install a pillar base at a certain distance from the extending direction of the door when it is closed. As a result, it is possible to shorten the installation work time of the pillar base.

[0010] (2) In the railway vehicle described in (1), the covering portion may be formed in a substantially arc shape centered on the rotation axis in the plan view. According to the aspect described in (2) above, since the covering portion that can be exposed to the outside and can be conspicuous is formed in a substantially arc shape, it is possible to further suppress a decrease in the appearance around the door. (3) In the railway vehicle described in (1) or (2), a pillar Kise is installed, the pillar Kise has a plate-shaped substrate portion formed along the extending direction of the door when it is closed, a plate-shaped intermediate plate portion formed substantially at a right angle from the end portion on the door side of the substrate portion toward the side opposite to the passage, and a plate-shaped door receiving plate portion formed substantially at a right angle from the end portion on the side opposite to the passage of the intermediate plate portion toward the side opposite to the substrate portion. The intermediate plate portion faces the covering portion in a separated state in the extending direction of the door when the door is closed. The door receiving plate portion may face the covering portion in a separated state in the direction orthogonal to the extending direction of the door when the door is closed. According to the aspect described in (3) above, it is possible to suppress a decrease in the appearance between the pillar base and the door. (4) In the railway vehicle described in (3), the separation distance between the intermediate plate portion and the covering portion in the extending direction of the door when the door is closed may be 25 mm or more and 30 mm or less. If the separation 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 deteriorate. On the other hand, if it is too short, it will hinder the installation of the pillar base. Therefore, according to the aspect described in (4) above, it is possible to effectively suppress the deterioration of the appearance around the door while shortening the installation work time of the pillar base.

Effect of the Invention

[0011] According to the present invention, it is possible to shorten the installation work time of the pillar base while suppressing the deterioration of the aesthetic appearance around the door that constitutes the partition panel in the entrance platform.

Embodiment for Carrying out the Invention

[0013] <First Embodiment> Next, the railway vehicle according to the first embodiment of the present invention will be described with reference to the drawings. Figure 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 convenience, it is assumed that the vehicle 1 travels to the left in FIG. 1, and with respect to the longitudinal direction of the vehicle body 10 (vehicle body longitudinal direction) 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 vehicle body 10 (vehicle body width direction), the right side and the left side in the situation facing from the rear side to the front side in the vehicle body longitudinal direction 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 vehicle body 10 of the vehicle 1 includes a pedestal frame 11 forming the floor surface of the vehicle body 10, a pair of gable structures 12 erected at both ends of the pedestal frame 11 in the vehicle body longitudinal direction, a pair of side structures 13 erected at both ends of the pedestal frame 11 in the vehicle body width direction, and a roof structure 14 disposed at the upper ends of the pair of gable structures 12 and the pair of side structures 13 to form the roof of the vehicle body 10.

[0015] The vehicle body 10 is divided into a passenger compartment R1, a front entrance platform R2, and a rear entrance platform R3. Along the vehicle body longitudinal direction, in order from the front side, it is divided into the front entrance platform R2, the passenger compartment R1, and the rear entrance platform R3. 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 vehicle body longitudinal direction 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] On the front access platform R2, a passage 30 having a substantially cross-shaped plan view is formed. Hereinafter, the portion parallel to the longitudinal direction of the vehicle body in the passage 30 is referred to as "first passage 30A", and the portion parallel to the vehicle body width direction is referred to as "second passage 30B". The first passage 30A is linearly formed at the center in the vehicle body width direction of the front access platform R2. The second passage 30B is linearly formed near the rear side of the front access platform R2.

[0019] Note that the plan view shape of the passage 30 formed on the front access platform R2 is not limited to a substantially cross shape and may be changed as appropriate. For example, the plan view shape of the passage 30 may be a substantially T shape or a substantially L shape. Furthermore, the plan view shape of the passage 30 may be, for example, linear, curved, or wavy. When the plan view shape of the passage 30 is substantially linear, the passage 30 may be formed on one side in the vehicle body width direction of the front access platform R2 or may be formed at the center in the vehicle body width direction of the front access platform R2.

[0020] The passage 30 is partitioned by a floor panel 31, a partition panel 32, and a ceiling panel 33 (see FIG. 3). The floor panel 31 is supported by the underframe 11 located directly below, and the ceiling panel 33 is supported by the roof structure 14 located directly above (see FIG. 3). Also, the partition panel 32 is erected substantially at a right angle to the floor panel 31 and is disposed between the floor panel 31 and the ceiling panel 33 (see FIG. 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 disposed on the front side and the left side of the intersection of the first passage 30A and the second passage 30B. The front right partition panel 32B is disposed on the front side and the right side of the intersection of the first passage 30A and the second passage 30B. The rear left partition panel 32C is disposed on the rear side and the left side of the intersection of the first passage 30A and the second passage 30B. The rear right partition panel 32D is disposed on the rear side and the right side 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 have a straight portion (first straight portion) that faces the first passage 30A in the vehicle body width direction, in other words, that partitions the first passage 30A, a straight portion (second straight portion) that faces the second passage 30B in the vehicle body longitudinal direction, in other words, that partitions the second passage 30B, and a corner portion that connects the first straight portion and the second straight portion in a substantially 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 washbasin room R23 are installed in order from the front side to the rear side. Further, on the side of the front left partition panel 32A opposite the passage 30 and on the rear side of the washbasin room R23, a switchboard M is housed. Also, on the side of the front right partition panel 32B opposite the passage 30, a first machine room R24 and a second machine room R25 are installed in order from the front side to the rear side.

[0024] Next, the front left partition panel 32A will be described. The front left partition panel 32A includes a housing 40 erected perpendicular to the floor 31 and a door 41 attached to the housing 40. As shown in FIG. 2, the door 41 is disposed at a portion (second straight portion) of the front left partition panel 32A that faces the second passage 30B. A switchboard M is housed on the side of the door 41 opposite the second passage 30B. That is, the door 41 is installed with respect to the switchboard M. In the following, with reference to the door 41, the side of the door 41 on the second passage 30B side (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] Also, the door 41 is disposed on one side in the extending direction of the front left partition panel 32A in plan view, in other words, at the end closer to the side structure 13 in the vehicle body width direction. And a pillar base 42 is installed between the door 41 and the side structure 13. The door 41 and the pillar base 42 are close to each other in the vehicle body width direction.

[0026] FIG. 3 is a view taken along the line A-A in FIG. 2. FIG. 4A is an end face view of a cross section taken along the line B-B in FIG. 3, and FIG. 4B is an end face view of a cross section taken along the line C-C in FIG. 3.

[0027] An opening 40A that is vertically long and substantially rectangular in a front view is formed in a portion (second straight portion) of the housing 40 that faces the second passage 30B. A door 41 is attached to the opening 40A.

[0028] The door 41 is shaped to be vertically long and substantially rectangular in a front view, and has a main body portion 411 that constitutes most of the door except for the left end portion, and a covering portion 412 that constitutes the left end portion. Further, the door 41 is rotatably supported by a vertical frame 401 that constitutes the housing 40 via a hinge 43 having a rotation axis X1.

[0029] The vertical frame 401 is entirely composed of a steel material having an L-shaped cross section with the vehicle body height direction as the axial direction, and extends in the vehicle body height direction. The vertical frame 401 constitutes an end portion 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 portion of the main body portion 411 is joined to the front surface of the vertical frame 401 via the hinge 43. Note that the vertical frame 401 is fixed to a side entrance pillar 35 described later via a receiving member 46.

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

[0031] Note that the structure of the door-side fixture 44 can be appropriately set within the range where the door 41 and the hinge 43 can be fixed. The door-side fixture 44 includes a main body 441 made of a steel material with an L-shaped cross-section, bolts 442 and 443, and a spacer 444. The main body 441 and the main body portion 411 are fixed by the bolt 442, and the main body 441 and the hinge 43 are fixed via the spacer 444 by the bolt 443.

[0032] Also, the structure of the housing-side fixture 45 can be appropriately set within the range where the housing 40 and the hinge 43 can be fixed. The housing-side fixture 45 includes a main body 451 made of a steel material with a substantially U-shaped cross-section, bolts 452 and 453, and spacers 454 and 455. The main body 451 and the vertical frame 401 are fixed via the spacer 454 by the bolt 452, and the main body 451 and the hinge 43 are fixed via the spacer 455 by the bolt 453.

[0033] The rotation axis X1 of the hinge 43 is parallel to the vehicle body height direction. The door 41 can rotate clockwise and counterclockwise within the range from the position shown by the solid line in Fig. 4A to the position of the two-dot chain line that has advanced 90 degrees clockwise in a plan view around the rotation axis X1. When the door 41 is rotated, the opening 40A is opened and closed.

[0034] Note that the door 41 shown in Figs. 3, 4A, and 4B is in a state of completely closing the opening 40A. Hereinafter, the position of the door 41 shown in Figs. 3, 4A, and 4B with respect to the housing 40 is referred to as the "fully closed position". Also, the position of the two-dot chain line that has advanced 90 degrees clockwise in a plan view from the fully closed position of the door 41 shown in Fig. 4A with respect to the housing 40 is referred to as the "fully open position".

[0035] The pillar keeper 42 extends generally along the vehicle body height direction. There are three major types of cross-sectional shapes (pillar keeper cross-sectional shapes) of the pillar keeper 42 orthogonal to the vehicle body height direction. That is, the pillar keeper cross-sectional shape is different at the upper side, the lower side, and the center. Hereinafter, the upper side of the pillar keeper 42, the lower side of the pillar keeper 42, and the center of the pillar keeper 42 are referred to as "pillar keeper upper side 42U", "pillar keeper center 42C", and "pillar keeper lower side 42D", respectively.

[0036] The pillar keeper upper side 42U has, in a cross-section orthogonal to the vehicle body height direction, a substrate portion 421 that is parallel to the vehicle body width direction and is generally plate-shaped, an intermediate plate portion 422 that is orthogonal to the back side from the right end portion of the substrate portion 421 and is parallel to the vehicle body longitudinal direction and is generally plate-shaped, and a door receiving plate portion 423 that is orthogonal to the right side from the back end portion of the intermediate plate portion 422 and is parallel to the vehicle body width direction and is generally plate-shaped (see FIG. 4A). As for the magnitude relationship of the longitudinal lengths of the respective portions in the extending direction, the longitudinal length of the substrate portion 421 > the longitudinal length of the door receiving plate portion 423 > the longitudinal length of the intermediate plate portion 422.

[0037] The substrate portion 421 is formed in the extending direction of the main body portion 411 when the door 41 is completely closed. The intermediate plate portion 422 is formed away from the covering portion 412 to the left side (the side of the vehicle body width direction side structure 13) when the door 41 is completely closed. The door receiving plate portion 423 is formed in the vehicle body longitudinal direction at the hinge 43, further on the back side than the covering portion 412, and in the vehicle body width direction across the outside of the door 41, the covering portion 412, and the main body portion 411 when the door 41 is completely closed. In this embodiment, the right end portion (inside the vehicle body) of the door receiving plate portion 423 in the vehicle body width direction is further bent at a substantially right angle to provide an end rising portion 4231, maintaining the flatness of the door receiving plate portion 423 and suppressing a decrease in appearance. Further, since the rigidity is enhanced by the end rising portion 4231, even if the pillar keeper 42 is slightly deformed due to temperature change, contact with passengers, etc., the original shape is maintained at the narrow gap portion between the hinge 43 and the door receiving plate portion 423, and contact between the opposing hinge 43 and the covering portion 412 and the door receiving plate portion 423 can be prevented. Therefore, even if the pillar keeper 42 is somewhat deformed due to temperature change, contact with passengers, etc., the original shape is maintained at the narrow gap portion between the hinge 43 and the door receiving plate portion 423, and contact between the opposing hinge 43 and the covering portion 412 and the door receiving plate portion 423 can be prevented.

[0038] In a cross-section orthogonal to the vehicle body height direction, the center 42C of the pillar socket has a substrate 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 protruding portion 424 having a substantially U-shaped cross-section that connects the right end portion of the substrate portion 421 and the left end portion of the door receiving plate portion 423 (see FIG. 4B).

[0039] The substrate portion 421 related to the center 42C of the pillar socket is integrally continuous with the substrate portion 421 related to the upper portion 42U of the pillar socket. However, although the left tip of the substrate portion 421 related to the center 42C of the pillar socket and the left tip of the substrate portion 421 related to the upper portion 42U of the pillar socket are aligned in the vehicle body height direction, the vehicle body width direction length of the substrate portion 421 related to the center 42C of the pillar socket is shorter than the vehicle body width direction length of the substrate portion 421 related to the upper portion 42U of the pillar socket.

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

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

[0042] The intermediate protruding portion 424 related to the center 42C of the pillar socket is formed to protrude toward the back side as a whole, and in a cross-section orthogonal to the vehicle body height direction, has a flat plate portion 424A that is parallel to the vehicle body width direction and is generally plate-shaped, a left connecting portion 424B that connects the flat plate portion 424A and the substrate portion 421, and a right 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 connection portion 424B smoothly connects the left tip of the flat plate portion 424A and the right tip of the substrate portion 421, and is formed in a substantially arc shape that protrudes substantially to the left as a whole. The right connection portion 424C smoothly connects the right tip of the flat plate portion 424A and the left tip of the door receiving plate portion 423, and is formed in a substantially arc shape that protrudes substantially to the right as a whole.

[0044] Although not shown, the lower side 42D of the pillar base has, in a cross-section orthogonal to the vehicle height direction, as a whole, the substrate portion 421, the intermediate plate portion 422, and the door receiving plate portion 423, similar to the upper side 42U of the pillar base (see FIG. 3). However, the length of the substrate portion 421 in the vehicle width direction becomes shorter as it goes downward. Also, the position of the left end of the substrate portion 421 becomes more to the right as it goes downward.

[0045] Also, a handrail 34 is installed inside the pillar base 42. The handrail 34 extends along the vehicle height direction. And the handrail 34 is disposed on the front side of the flat plate portion 424A in the longitudinal direction of the vehicle body, is exposed at the portion of the center 42C of the pillar base, and is covered by the lower side 42D of the pillar base at the portion of the lower side 42D of the pillar base.

[0046] On the rear side of the pillar base 42 in the longitudinal direction of the vehicle body, specifically, on the rear side of the flat plate portion 424A in the longitudinal direction of the vehicle body, a side entrance pillar 35 with an axial direction parallel to the vehicle height direction stands vertically on the floor 30. A buffer member 36 is interposed between the side entrance pillar 35 and the flat plate portion 424A in a state where both are in close contact with each other.

[0047] A boarding and alighting door 22 is installed at the side entrance portion 13h. Also, outside pillars 37A of the door pocket are arranged on the outside of both outer edges in the longitudinal direction of the vehicle body of the side entrance portion 13h, and inside pillars 37B of the door pocket are arranged on the inside of the vehicle body. The outside pillars 37A of the door pocket and the inside pillars 37B of the door pocket stand vertically on the base frame 11 substantially perpendicularly. And the boarding and alighting door 22 is slidable along the longitudinal direction of the vehicle body between the outside pillars 37A of the door pocket and the inside pillars 37B of the door pocket.

[0048] The inner pillar 37B of the door pocket and the pillar base 42 are installed separately in the longitudinal direction of the vehicle body. The inner pillar 37B of the door pocket is arranged on the rear side of the pillar base 42. Also, the right end of the inner pillar 37B of the door pocket and the left end of the substrate portion 421 of the pillar base 42 are aligned along the longitudinal direction of the vehicle body at substantially the same position. And the pillar base 42 is fixed to the pillar base receiving member 38 fixed to the inner pillar 37B of the door pocket via a buffer member 39 at the left end portion of the back surface of the substrate portion 421. Note that the buffer member 39 is adhered to both the pillar base receiving member 38 and the substrate portion 421.

[0049] Next, the covering portion 412 and the gap S1 between the door 41 and the pillar base 42 will be described. The covering portion 412 is formed at the left end portion of the door 41, in other words, at the end portion closer to the pillar base 42 and the side structure 13 in the extending direction of the door 41 in plan view. In the first embodiment, the portion located on the left side of the plane parallel to the longitudinal direction of the vehicle body including the straight line parallel to the longitudinal direction of the vehicle body passing through the rotation axis X1 of the door 41 constitutes the covering portion 412. Note that the covering portion 412 is formed continuously from the left end portion of the plate-like main body portion 411 which is vertically long in front view and is separated from the main body portion 411 for convenience, but the covering portion 412 and the main body portion 411 are integrally formed.

[0050] The covering portion 412 is formed to extend toward the back side in the longitudinal direction of the vehicle body over the entire length in the vehicle height direction of the main body portion 411. In plan view, the covering portion 412 is housed in a rectangular region having the intermediate plate portion 422 as the short side and the door receiving plate portion 423 as the long side. And in the state where the door 41 is completely closed, the covering portion 412 is entirely opposed to the intermediate plate portion 422 at a distance in the vehicle width direction and is opposed to 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 vehicle width direction.

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

[0052] In plan view, the shape of the covering portion 412 is an arc shape that protrudes toward the pillar base 42 side (left side) with the rotation axis X1 as the center. In a state where the door 41 is completely closed, the shape of the covering portion 412 in plan view is substantially symmetric with respect to a straight line parallel to the vehicle body width direction passing through the rotation axis X1.

[0053] Also, the front side of the main body portion 411 is formed flat. In plan view, the front side surface (outer surface of the main body portion) 411A of the main body portion 411 is parallel to the vehicle body width direction and is continuously formed 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 portion and the outer surface 412A of the covering portion in the vehicle body width direction is substantially the same as the position of the rotation axis X1 in the vehicle body width direction. And the outer surface 412A of the covering portion is formed in an arc shape in the clockwise direction with the rotation axis X1 as the center and the distance in the vehicle body longitudinal direction between the rotation axis X1 and the boundary K1 as the radius r1 from the boundary K1.

[0055] The position of the tip 412AT of the outer surface 412A of the covering portion in the vehicle body width direction is on the pillar base 42 side with respect to the position of the rotation axis X1 in the vehicle body width direction. Specifically, in a state where the door 41 is completely closed, at the center Taking a certain rotation axis X1 as the vertex, the angle formed by the half line connecting the vertex and the tip 412AT of the outer surface 412A of the covering portion and the half line parallel to the vehicle body width direction passing through the rotation axis X1 is about 60 degrees. On the other hand, in a state where the door 41 is completely closed, taking the rotation axis X1 which is the center as the vertex, the angle formed by the half line connecting the vertex and the boundary K1 which is the base end portion of the outer surface 412A of the covering portion and the straight line parallel to the vehicle body width direction passing through the rotation axis X1 is about 90 degrees.

[0056] For the outer surface 412A of the arc-shaped covering portion, the tangent line at the intersection point P1 between the straight line parallel to the vehicle body width direction passing through the rotation axis X1 and the outer surface 412A of the covering portion is parallel to the vehicle body longitudinal direction. Therefore, from the fully closed position to the fully open position of the door 41, the absolute position related to the intersection point P1 in the state where the door 41 is completely closed is always closest to the pillar joint 42 in the vehicle body width direction. That is, from the fully closed position to the fully open position of the door 41, the gap width H1 between the door 41 (covering portion 412) and the pillar joint 42 in the vehicle body width direction is 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. If the gap width H1 becomes too wide, the aesthetic sense will decrease. On the other hand, if the gap width H1 becomes too narrow, it may hinder the installation work of the pillar joint 42. Therefore, the gap width H1 is preferably 20 mm to 35 mm. Further, the gap width H1 is preferably 25 mm to 30 mm.

[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 vehicle body longitudinal direction, but it is the portion closest to the door receiving plate portion 423 among the outer surface 412A of the covering portion. And the distance in the vehicle body longitudinal direction between the tip 412AT of the outer surface 412A of the covering portion and the door receiving plate portion 423 in the state where the door 41 is completely closed is set to be longer than the distance when the distance in the vehicle body longitudinal direction between the outer surface 412A of the covering portion and the door receiving plate portion 423 is the shortest until the door 41 takes the fully open position. This is to prevent the covering portion 412 from contacting the door receiving plate portion 423 and hindering the opening and closing of the door 41.

[0058] When the door 41 rotates from the fully closed state, the outer surface 412A of the covering portion rotates along a locus following an arc in a plan view in the fully closed state. Therefore, the distance in the longitudinal direction of the vehicle body between the outer surface 412A of the covering portion and the door receiving plate portion 423 becomes shorter from the state where the door 41 is fully closed until the door 41 reaches the fully open position. Specifically, the distance in the longitudinal direction of the vehicle body between the outer surface 412A of the covering portion and the door receiving plate portion 423 on a straight line parallel to the longitudinal direction of the vehicle body passing through the rotation axis X1 becomes the shortest. And after the tip 412AT of the outer surface 412A of the covering portion reaches the straight line, the shortest distance in the longitudinal direction of the vehicle body between the outer surface 412A of the covering portion and the door receiving plate portion 423 becomes constant.

[0059] Also, in the state where the door 41 is fully 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 substrate 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 in the state where the door 41 with 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 fully closed, the space between the door 41 and the pillar keel 42 is shielded, and it is prevented that the back side thereof can be seen.

[0060] As described above, according to the vehicle 1, (1) it includes a partition panel 32 that partitions the passage 30 of the front entrance platform R2 and houses in-vehicle equipment. The front left partition panel 32A in the partition panel 32 includes a housing 40 having an opening 40A and a door 41 attached to the opening 40A. The door 41 is rotatably supported by a vertical frame 401 of the housing 40 via a hinge 43 having a rotation axis X1 parallel to the vehicle height direction. The rotation axis X1 is formed at an end on one side (the left side in the vehicle width direction) of the door 41 in a plan view. And further in the vehicle 1, the door 41 has a plate-shaped main body portion 411 and a covering portion 412 formed to extend from the tip on one side (the left side in the vehicle width direction) of the main body portion 411 in a plan view to the back side (the side opposite to the second passage 30B), and the main body portion 41 1 is joined to the hinge 43 on the back side (opposite side to the second passage 30B), and the covering portion 412 faces the hinge 43 in the extending direction of the main body portion 411 in a plan view and covers the hinge 43. Here, the covering portion 412 formed by extending from the tip of one side (left side in the vehicle body width direction) of the plate-shaped main body portion 411 in a plan view to the back side (opposite side to the second passage 30B) faces the hinge 43 joined to the main body portion 411 on the back side (opposite side to the second passage 30B) and covers the hinge 43. Therefore, the portion connecting to the back side (opposite side to the second passage 30B) of the main body portion 411 including the hinge 43 is shielded. Accordingly, it is possible to suppress a deterioration in the appearance around the door 41. Furthermore, since the portion connecting to the back side (opposite side to the second passage 30B) of the main body portion 411 including the hinge 43 is shielded in this way, the pillar base 42 can be installed at a certain distance with respect to the extending direction of the door 41 when it is closed. As a result, even when the pillar base 42 is installed behind the door 41, it is possible to shorten the installation work time of the pillar base 42.

[0061] Also, according to the 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 that can be exposed to the outside and be conspicuous is formed in an arc shape, it is possible to further suppress a deterioration in the appearance around the door 41.

[0062] Furthermore, according to the vehicle 1, a pillar base 42 (pillar member) extending along the vehicle body height direction is installed. The cross-section of the pillar base 42 (pillar member) orthogonal to the vehicle body height direction is formed by a plate-like substrate portion 421 formed along the extending direction of the door 42 when it is closed, a plate-like intermediate plate portion 422 formed at a substantially right angle from the end of the substrate portion 421 on the door 41 side toward the back side (opposite side to the second passage 30B), and a plate-like door receiving plate portion 423 formed at a substantially right angle from the end of the intermediate plate portion 422 on the back side (opposite side to the second passage 30B) toward the side opposite to the substrate portion 421. The intermediate plate portion 422 faces the covering portion 412 in a separated state in the extending direction of the door 41 when the door 41 is closed, and the door receiving plate portion 423 faces the covering portion 412 in a separated state in the direction orthogonal to the extending direction of the door 41 when the door 41 is closed. Therefore, it is possible to suppress a decrease in the appearance between the pillar base 42 (pillar member) and the door 41. 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 aesthetics around the door 41 will deteriorate, while if it is too short, it will hinder the installation of the pillar base 42 (pillar member). Therefore, according to the 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 it is possible to effectively suppress a decrease in the appearance between the door 41 and the pillar base 42 (pillar member) while shortening the installation work time of the pillar base 42 (pillar member).

[0063] <Modification example> Next, a modification example of the vehicle 1 according to the first embodiment will be described. The above-described first embodiment can be appropriately modified without changing the gist of the present invention.

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

[0065] The planar shape of the covering portion 412 may also be changed as appropriate. For example, compared with the case of the first embodiment, the tip of the covering portion 412 may be further extended along an arc shape or may be shortened. Alternatively, the planar 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 contact the door receiving plate portion 423 when the door 41 rotates between the fully closed position and the fully open position.

[0066] Note that this embodiment is merely an example and does not limit the present invention in any way. Therefore, the present invention can naturally be variously modified without departing from the gist thereof.
