Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rear structure of a vehicle such as an automobile, and more particularly to a rear structure of a vehicle having excellent aerodynamic characteristics.
[0002]
[Prior art]
In order to improve the performance of vehicles such as automobiles, it is preferable to reduce the air resistance of the vehicle body as much as possible while driving. For this reason, for example, "Honda Insight / Prius Comparison Test" in the magazine "CAR GRAPHIC-2001" As described in this article, attempts have been made to make the shape of the body of a station wagon type vehicle into a teardrop type.
[0003]
[Problems to be solved by the invention]
If the shape of the vehicle body is a teardrop shape, the aerodynamic characteristics of the vehicle can be improved by reducing the air resistance of the vehicle body and reducing the negative pressure behind the vehicle. Compared to the shape of the vehicle, the roof at the rear end of the vehicle must be lowered and the rear end must be extended rearward, increasing the overall length and weight of the vehicle, and creating a room at the rear end of the vehicle. There is a problem that a narrow vehicle interior space that is difficult to use effectively is created, and further, the rear visibility of the vehicle is affected.
[0004]
In addition, since the roof at the rear end of the vehicle has to be lowered and the inclination angle has to be increased, an opening is provided at the rear end of the vehicle, and the opening is pivotally attached to the vehicle body at the upper edge. In the case of a vehicle that is opened and closed by a door, it is difficult to secure a sufficiently large back door, and water droplets on the roof are easier to move to the rear of the vehicle than in the conventional case. There is a problem that when the door is opened, water drops easily enter the passenger compartment.
[0005]
The present invention has been made in view of the above-described problems when the shape of a vehicle body is a teardrop type. The main object of the present invention is to make the rear end of the roof of the vehicle body too low. It is to solve the above-mentioned various problems while improving the aerodynamic characteristics of the vehicle by making the shape of the vehicle body as close to the teardrop shape as possible without increasing the inclination angle.

[0007]
According to the configuration of the first aspect, the transparent region has a first surface portion that defines a part of the roof surface of the vehicle and a second surface portion that defines a part of the rear end surface of the vehicle. Therefore, it becomes possible to make the shape of the vehicle body as close as possible to the teardrop shape by the rear end portion and the first surface portion of the roof of the vehicle body without excessively lowering the rear end portion of the roof of the vehicle body, In addition, since the second surface portion defines a part of the rear end surface of the vehicle, an increase in the total length and weight of the vehicle due to the rear end portion of the vehicle being extended rearward is avoided. There is no narrow vehicle interior space that is difficult to use effectively as a living room at the rear end, and further, the rear surface visibility of the vehicle is ensured by the first surface portion that defines a part of the see-through region. .

  And the above claims4With this configuration, the see-through area defines the first surface portion that defines a part of the teardrop-shaped roof surface of the vehicle and the part of the rear end surface of the vehicle as viewed from the side of the vehicle. The second surface portion and a curved connection portion that integrally connects the first and second surface portions, and the upper edge of the first surface portion is higher than the upper edge of the rear view mirror when viewed from the center in the vehicle width direction. In addition, since the lower edge of the first surface portion is lower than the lower edge of the rearview mirror, the same function and effect as in the case of the configuration of claim 1 can be obtained.
[0010]
  And the above claims4According to this configuration, the radius of curvature of the connecting portion is substantially the minimum value within the range of the radius of curvature that can be seen through in the vehicle front-rear direction, so that the rear of the vehicle can be visually recognized through the connecting portion. Therefore, the rear visibility of the vehicle is further improved as compared with the case of the configuration of claim 1.
  According to the configuration of the fifth aspect, in addition to obtaining the operational effect of the configuration of the fourth aspect, the length between the upper edge of the back door and the center of the connecting portion is the center of the connecting portion. Compared to the structure that is set to be larger than the length between the lower edge of the back door, the vehicle interior space at the rear end of the vehicle can be widened to secure the rear seat, It becomes possible to reliably prevent the overall length from becoming longer than necessary and the increase in vehicle weight due to this.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will now be described in detail with reference to a few preferred embodiments with reference to the accompanying drawings.
[0043]
First embodiment
FIG. 1 is a schematic side sectional view showing a first embodiment of the rear structure of a vehicle according to the present invention applied to a two-seat type station wagon type passenger car, and FIG. 2 is a perspective view of the back door of the first embodiment. FIG. 3 is an enlarged partial sectional view of the back door taken along line III-III in FIG. 2, and FIG. 4 is an enlarged partial sectional view of the back door showing the connecting portion shown in FIG. FIG.
[0044]
In these drawings, reference numeral 10 denotes a vehicle body that defines a passenger compartment 12 therein, and reference numerals 14 and 16 denote a driver and a rear seat occupant seated on a driver seat 15 and a rear seat 17, respectively. The vehicle body 10 has a substantially teardrop shape as viewed from the side of the vehicle due to the front nose 18, the windshield 20, the roof 22, and the back door 24. A rear view mirror 26 is attached to the inner surface of the front end of the roof 22. Although not shown in the figure, the roof 22 is highest at the center in the vehicle width direction and gradually lowers toward both sides in the vehicle width direction, as in the case of a normal vehicle.
[0045]
The back door 24 is pivotally attached to the rear edge (rear header 22A) of the roof 22 at the upper edge by a pair of hinge members 28 having a known structure spaced apart from each other in the vehicle width direction. The opening 30 is opened and closed. In the illustrated embodiment, the back door 24 has a metal back door main body 32 having a box shape when viewed from the rear of the vehicle. The back door main body 32 is made of, for example, a press-formed steel plate or an aluminum alloy plate. Is formed. The back door main body 32 is bent so as to form a “<” shape toward the rear and upward of the vehicle as viewed from the side of the vehicle, and the back door main body 32 is first fixed by a mechanical fixing means such as an adhesive or a screw. A transparent plate 34 and a second transparent plate 36 are fixed.
[0046]
As shown in detail in FIGS. 2 to 4, the first transparent plate 34 and the second transparent plate 36 are integrally formed at an obtuse angle with respect to each other by a connecting member 38 extending in the lateral direction of the vehicle. It is connected. The first transparent plate 34 and the second transparent plate 36 are formed of a colorless or colored transparent plate material such as glass or polycarbonate, and cooperate with each other to define the rear window.
[0047]
In particular, in the illustrated embodiment, the connecting member 38 has a substantially bent H-shaped cross-sectional shape, and is formed of a rigid material that cannot be seen through such as reinforced plastic or metal. The first transparent plate 34 and the second transparent plate 36 are integrally connected by having their lower edge and upper edge fitted in the corresponding grooves 38A and 38B of the connecting member 38 and fixed by adhesion or press-fitting. .
[0048]
As shown in detail in FIGS. 2 and 3, the first transparent plate 34 defines a region 40 </ b> A that can be seen through in the vehicle front-rear direction between the upper side 32 </ b> A of the back door body 32 and the connection member 38. Along with the upper side portion 32A of the back door body 32, a part of the teardrop type roof surface of the vehicle is defined. In contrast, the second transparent plate 36 defines a region 40B that can be seen through in the vehicle front-rear direction between the lower side portion 32B of the back door body 32 and the connection member 38, and the lower side portion 32B of the back door body 32. A part of the rear end of the vehicle is defined by working together.
[0049]
Accordingly, since the rear view is possible through either the first transparent plate 34 or the second transparent plate 36, the roof 22 of the vehicle body 10 extends to the position of the connecting member 38, for example, in order to make the vehicle body into a teardrop shape. Compared to the case of the vehicle, the rear visibility of the vehicle can be ensured, and the size of the opening 30 at the rear end of the vehicle body can be increased to enlarge the back door 24. As a result, it is possible to easily take in and out the luggage and the like performed through the back door.
[0050]
As shown in FIG. 1, when viewed in a vertical cross section along the vehicle longitudinal direction at the center in the vehicle width direction, an upper region 40 </ b> A that can be seen through in the vehicle longitudinal direction defined by the first transparent plate 34. The upper edge, more precisely, the upper edge of the region 40A that can be seen through when the driver visually recognizes rearward through the rearview mirror 26 is higher than the upper edge of the rearview mirror 26 and can be seen through in the vehicle front-rear direction. The lower edge of the region 40 </ b> A, that is, the upper edge of the connecting member 38 is lower than the lower edge of the room mirror 26.
[0051]
Therefore, the driver visually recognizes a region higher than the upper edge of the rear-view mirror 26 and a lower region than the lower edge of the rear-view mirror 26 when viewing rearward through the rear-view mirror 26 and the transparent region 40A. In particular, the rear visibility of the vehicle can be improved as compared with the case where the upper edge of the region 40A that can be seen through in the vehicle front-rear direction is lower than the upper edge of the rear-view mirror 26 at the rear of the vehicle.
[0052]
In the illustrated embodiment, the first transparent plate 34 and the second transparent plate 36 have curved surfaces slightly curved upward and rearward, respectively, but at least one of these transparent plates is a vehicle. It may be flat when viewed in the lateral direction. The inclination angle of the first transparent plate 34 with respect to the horizontal direction is the largest at the lower edge, and the inclination angle θd at the lower edge is 15 ° as viewed in the vertical cross section along the vehicle longitudinal direction at the center in the vehicle width direction. The inclination angle θu at the upper edge is set to be equal to or less than the inclination angle θd.
[0053]
Accordingly, even when the vehicle is traveling at high speed, the air flowing toward the rear of the vehicle along the roof 22 of the vehicle body 10 does not peel from the first transparent plate to the lower edge of the first transparent plate 34. Can be reliably prevented from deteriorating the aerodynamic characteristics of the vehicle due to air separation, and the effective vehicle interior space at the rear end of the vehicle can be reduced. Can be wide.
[0054]
Further, when viewed in a vertical cross section along the vehicle longitudinal direction at the center in the vehicle width direction, the length between the upper edge of the back door 24 and the center of the connecting member 38 is the center of the connecting member 38 and the lower edge of the back door 24. The length between the upper edge and the lower edge of the first transparent plate 34 is set to be smaller than the length between the upper edge and the lower edge of the second transparent plate 36. It is set small.
[0055]
Therefore, the length between the upper edge of the back door 24 and the center of the connecting member 38 is set larger than the length between the center of the connecting member 38 and the lower edge of the back door 24. It is possible to widen an effective vehicle interior space at the rear end of the vehicle and secure a rear seat, and to reliably prevent an increase in the total length of the vehicle and an increase in vehicle weight due to this. Can do.
[0056]
Further, as shown in FIG. 3, when the driver of the standard physique 14 is in a standard seating state, the connecting member is viewed when the driver visually recognizes the rear through the room mirror 26 with the eyes 14A. If the blind spot formed by the connection member 38 is the first blind spot 42 and the blind spot formed by the connecting member 38 is the second blind spot 44 when the driver looks back and looks directly behind, The vertical width Wb and the height of the driver's eyes 14A, the rearview mirror 26, and the connecting member 38 are such that the second blind spot 44 is positioned above the lower edge of the first blind spot 42.
[0057]
Accordingly, when the driver visually recognizes the vehicle through the rear mirror 26, the driver can surely recognize the vehicle by turning back and directly viewing at least the lower part of the first blind spot 42 formed by the connecting member 38. The rear visibility of the vehicle can be improved as compared with the case where the height relationship of the connecting member 38 and the like is a relationship in which the first blind spot 42 is included in the second blind spot 44.
[0058]
In particular, in the illustrated embodiment, as shown in FIG. 1, the rear seat (or rearmost seat in the case of a three-row vehicle) 17 is set to the standard position. The upper edge of the lower vehicle front-rear area 40B, that is, the lower edge of the connecting member 38 is more than the straight line 45A connecting the lower edge of the rear mirror 26 and the upper edge of the seat back of the rear seat 17. The lower edge of the region 40B that is located above and can be seen through in the vehicle longitudinal direction on the lower side, that is, the upper edge of the lower side portion 32B of the back door body 32 is located below the straight line 45A.
[0059]
Accordingly, the driver can surely see the rear region of the vehicle close to the vehicle through the rear mirror 26 and the region 40B that can be seen through in the vehicle longitudinal direction on the lower side, and the upper edge of the reflector of the rear mirror 26 and Since the connecting member 38 is shown between the lower edge and the rear edge of the vehicle, the connecting member 38 can be used as a reference when visually checking the distance to the object behind the vehicle, for example, the following vehicle. Compared with the case where the upper edge of the lower side portion 32B of the main body 32 is positioned above the straight line 45A, the visibility of the region behind the vehicle close to the vehicle can be improved.
[0060]
Further, in the illustrated embodiment, when the rear seat 17 is set at the standard position, the upper edge of the lower region 40B that can be seen through in the vehicle longitudinal direction, that is, the lower edge of the connecting member 38 is The lower edge of the area 40B that is located above the straight line 45B that connects the lower edge of the rear mirror 26 and the upper edge of the headrest of the rear seat 17 and can be seen through in the vehicle longitudinal direction, that is, the back door body 32. The upper edge of the lower side portion 32B is located below the straight line 45B.
[0061]
Therefore, even when the driver visually recognizes the rear of the vehicle through the rear mirror 26 and above the headrest of the rear seat 17, the driver can see the vehicle close to the vehicle through the lower region 40 </ b> B that can be seen through in the vehicle front-rear direction. The rear region can be surely seen, and the visibility of the region behind the vehicle close to the vehicle is higher than when the upper edge of the lower side portion 32B of the back door body 32 is located above the straight line 45B. Can be improved.
[0062]
As shown schematically in FIG. 5, the distance in the vehicle front-rear direction between the rearview mirror 26 and the driver's 14 eyes 14A is L1, and the driver's eyes and the connecting member 38 of the back door 24 are connected to each other. When the distance in the vehicle front-rear direction is L2 and the vertical widths of the rearview mirror and the connecting member are Wa and Wb, respectively, the vertical width Wb ′ of the connecting member reflected on the rearview mirror when the rearview mirror is a plane mirror is It is represented by the following formula 1.
[0063]
Wb '= WbL1 / (L1 + L2) (1)
[0064]
In the illustrated embodiment, the vertical width of the connecting member 38 is set to be less than or equal to half of the vertical width of the room mirror 26, preferably less than or equal to one-third. Generally, L1 / (L1 + L2) is 5 Since the rearview mirror is generally a convex mirror, the vertical width Wb 'of the connecting member reflected on the rearview mirror is about 1/10 or less of the vertical width Wa of the rearview mirror, preferably 1/15. Therefore, it is possible to reliably prevent a connecting member that is substantially non-transparent from becoming a serious obstacle to the rear view of the vehicle by the rearview mirror.
[0065]
In the first embodiment described above, the first transparent plate 34 and the second transparent plate 36 defining the first surface portion and the second surface portion are separate members. As shown in the first modification, the first transparent plate 34 and the second transparent plate 36 are formed of a bent portion 35A as a connecting portion in which one transparent plate member 35 is not transparent in the vehicle longitudinal direction. In that case, the connecting member 38 can be omitted to reduce the number of parts, and the strength of the transparent region of the back door 24 can be improved. .
[0066]
Further, according to the first modification, the vertical width Wb2 of the non-perspective area by the bent portion 35A can be made much smaller than the vertical width Wb of the non-transparent area in the first embodiment. Therefore, the blind spots 42 and 44 formed by the bent portion 35A when the driver visually recognizes backward can be made much smaller than in the case of the first embodiment, and thus in the case of the first embodiment. In comparison, the rear visibility of the vehicle can be improved.
[0067]
Further, in this first modification, the vertical width Wb2 of the region that cannot be seen through and the heights of the driver's eyes 14A, the rearview mirror 26, and the bent portion 35A are as shown in FIG. In the area behind the rear end 10A, the second blind spot 44 is set so as not to overlap the first blind spot 42, so that according to this first modification, the driver can By looking back, the region behind the rear end 10 </ b> A of the vehicle in the blind spot 42 generated when visually recognizing the rear via the rear mirror 26 can be reliably visually recognized rearward.
[0068]
Further, as shown in FIG. 8 as the second modification example, for example, the curvature of the inner surface of the bent portion 35A is set larger than that of the first modification example, so that the flesh pressure of the bent portion 35A is increased in addition to the plate material 35. In this case, the vertical width Wb3 of the invisible region by the bent portion 35A is the vertical width of the invisible region in the first embodiment. While avoiding the increase in Wb, the strength of the transparent region of the back door 24 can be further improved as compared with the case of the first modification.
[0069]
Second embodiment
FIG. 9 is an enlarged partial sectional view showing a back door of a second embodiment of the rear structure of the vehicle according to the present invention applied to a two-seat type station wagon type passenger car, and FIG. 10 is a connection shown in FIG. It is an expanded partial sectional view of the back door which shows a portion. In these drawings, members substantially the same as those shown in FIGS. 1 to 6 are denoted by the same reference numerals as those shown in FIGS.
[0070]
In the second embodiment, as in the case of the first modification shown in FIG. 5, the rear window is a single see-through plate member 35 curved at a curved portion 35B as a connecting portion. However, the radius of curvature R of the curved portion 35B is set to a minimum value within the range of curvature that can be seen through in the vehicle front-rear direction, and other points are described above in the first embodiment. It is configured in the same way.
[0071]
Therefore, according to the second embodiment, in addition to obtaining substantially the same operational effects as those of the first embodiment described above, the blind spot formed by the connecting member 38 in the first embodiment. 42 and 44 do not occur. Therefore, in both cases where the driver visually recognizes rearward through the rearview mirror 26 and where the driver looks backward and visually recognizes backward, the vehicle is more than in the case of the first embodiment described above. The rear visibility of the can be improved.
[0072]
Third embodiment
FIG. 11 is a schematic sectional side view showing a third embodiment of the rear structure of the vehicle according to the present invention applied to a two-seat type station wagon type passenger car, and FIG. 12 is a rear structure of the vehicle according to the third embodiment. FIG. 13 and FIG. 14 are perspective views and plan views showing the back door of the third embodiment, respectively, and FIGS. 15 to 17 are XV-XV and FIG. It is an expanded sectional view of the upper edge part of a back door which follows XVI-XVI and XVII-XVII. In these drawings, members substantially the same as those shown in FIGS. 1 to 6 are denoted by the same reference numerals as those shown in FIGS.
[0073]
In the third embodiment, as in the case of the first modification shown in FIG. 6, the first transparent plate 34 and the second transparent plate 36 are connected to a single transparent plate 35. It is formed by being bent at a bent portion 35A as a portion, and the bent portion 35A extends downward on both sides in the vehicle width direction, whereby both side portions in the vehicle width direction of the first transparent plate 34 are formed. 34C also defines a part of the side surface of the rear end of the vehicle.
[0074]
Accordingly, the driver can visually recognize the oblique rear side of the vehicle through both side portions 34C in the vehicle width direction of the first transparent plate 34, so that the rear side of the vehicle is compared with the cases of the first and second embodiments described above. Visibility can be improved, and the bent portions 35A on both sides in the vehicle width direction can be used as a reference for visual measurement of the distance and direction to an object existing obliquely behind the vehicle.
[0075]
In the third embodiment, the back door main body 32 includes a frame 33 that defines an upper side portion and a side side portion of the back door main body 32, and the frame 33 is formed of a light metal hollow extruded material such as an aluminum alloy. It is formed by being plastically deformed into a shape. The plate member 35 extends slightly to the vehicle front side from the upper side portion 33A of the frame 33 and extends slightly to the outside in the vehicle width direction from the left and right side portions 33C of the frame 33.
[0076]
Accordingly, the frame 33 can be reduced in weight and can be formed at a lower cost than the case where the frame 33 is formed of a press-formed steel plate, and the upper side portion 33A and the left and right side portions 33C of the frame 33 are separated. The strength of the frame 33 can be improved as compared with the case of being formed by the above members and being joined by welding or the like.
[0077]
As shown in FIGS. 12 and 14, the upper edge of the plate member 35 as viewed from above the vehicle has an outer shape curved toward the rear of the vehicle between the pair of hinge members 28. It has an outer shape extending substantially in the lateral direction of the vehicle in the outer region in the width direction. The rear edge of the roof 22 of the vehicle body 10 also has an outer shape corresponding to the upper edge of the plate member 35, so that when the back door 24 is in the closed state, the upper edge of the plate member 35 is substantially the same as the rear edge of the roof 22 of the vehicle body 10. It extends to be parallel to.
[0078]
As shown in FIGS. 15 and 16, the rear end portion of the roof member 46 that defines the roof 22 of the vehicle body 10 is bent and deformed inward of the vehicle in front of the upper side portion 33 </ b> A and the side portion 33 </ b> C of the frame 33. A chamfered portion 48 is formed at a position close to the upper edge of the plate member 35. The lower edge portion of the rear end portion 46A of the roof member 46, which is curved and deformed inwardly, is fixed to the hollow rear header 22A, and the interior ceiling member 50A is fixed to the lower surface of the rear header 22A.
[0079]
A molding member 50 made of a slightly elastically deformable material such as plastic or hard rubber is fixed to the upper edge of the plate member 35. The outer surface of the molding member 50 substantially has a shape that smoothly connects the rear edge of the roof 22 of the vehicle body 10 and the upper edge of the plate member 35 and defines a part of the teardrop-shaped roof surface. When the back door 24 is in the closed state, the front edge of 50 is in light contact with the chamfered portion 48 or is slightly spaced apart therefrom.
[0080]
Therefore, as compared with the conventional structure in which the molding member 50 is not provided, the running resistance caused by the gap between the rear edge of the roof 22 of the vehicle body 10 and the upper edge of the back door 24 when the vehicle runs at high speed. And a wind noise can be reduced, and a portion of the rear end portion of the roof material 46 that is curved and deformed inwardly through a gap between the rear edge of the roof 22 of the vehicle body 10 and the upper edge of the back door 24. The amount of rainwater and dust that enters 46A can be reduced.
[0081]
A protrusion 52 protruding forward and slightly downward is formed on the upper edge of the plate member 35, and the molding member 50 is fixed by being fitted to the protrusion 52. A protrusion 56 is integrally formed on the upper edge of the front end of the upper side 33 </ b> A of the frame 33, and the molding member 50 is press-fitted between the protrusions 52 and 56. As shown in FIG. 16, brackets 58 are integrally formed on both sides of the upper edge of the plate member 35, and the brackets 58 extend in the lateral direction of the vehicle at positions spaced below the protrusions 52. The clip bar 60 is fixed integrally, and the molding member 50 is fitted between the protrusion 52 and the clip bar 60 on both sides of the vehicle.
[0082]
As shown in FIGS. 15 and 16, the pivot 62 of the back door 24 defined by the pair of hinge members 28 is located on the inner side of the roof 22 of the vehicle body 10 (vehicle compartment) at the center in the vehicle width direction. 12 on the both sides of the vehicle width direction on the outside of the roof 22 of the vehicle body 10. When the back door 24 is opened and closed, the back door 24 pivots around the pivot axis 62. When the back door 24 is opened to the fully open position shown in phantom lines in FIGS. The front edge is at least at the center in the vehicle width direction so as to come into close contact with the outer surface of the roof 22 of the vehicle body 10 so as to lightly contact the outer surface of the roof 22 of the vehicle body 10 or prevent the passage of water droplets.
[0083]
In this case, as described above, the upper edge of the plate member 35 as viewed from the upper side of the vehicle has an outer shape curved toward the rear of the vehicle between the pair of hinge members 28, and the rear edge of the roof 22 of the vehicle body 10 is the plate member 35. Since it has an outer shape corresponding to the upper edge, the upper edge of the plate member 35 and the rear edge of the roof 22 of the vehicle body 10 extend linearly in the lateral direction of the vehicle as viewed from above the vehicle, or the front of the vehicle. Compared to the case where the outer shape is curved toward the front, the front edge of the molding member 50 can be in light contact with or close to the outer surface of the roof 22 of the vehicle body 10 over a wide range in the vehicle width direction. It is possible to effectively prevent water droplets from moving between the front edge of the molding member 50 and the outer surface of the roof 22 of the vehicle body 10 and moving rearward over a wide range in the vehicle width direction.
[0084]
As shown in FIGS. 15 and 16, when the back door 24 is in the closed state, the position where the front edge of the molding member 50 abuts or is closest to the chamfered portion 48 is a point P, and at least in the vicinity of the point P. The inclination of the chamfer 48 is set at an angle at which the locus A of the point P around the pivot line 62 does not interfere with the outer surface of the chamfer 48. Therefore, when the back door 24 moves between the closed position and the fully opened position, the front edge of the molding member 50 does not galling the chamfered portion 48, so that dust or the like adheres to the front edge of the molding member 50. Even if it does, it can prevent that the chamfer 48 and the molding member 50 are damaged by opening and closing of the back door 24.
[0085]
Further, a seal member 64 made of an easily elastically deformable material such as rubber is fixed to the outer surface of the lower edge portion of the portion 46A that is curved and deformed inwardly of the vehicle, although not shown in detail in the drawing. The seal member 64 extends over the entire circumference of the opening 30 at the rear end of the vehicle body 10. The portions 46A of the roof member 46 that are curved and deformed inwardly of the vehicle have regions extending horizontally rearwardly of the vehicle on both sides in the vehicle width direction, and the seal member 64 cooperates with the portion 46A to allow water droplets to flow. A fence 66 that prevents entry into the passenger compartment 12 is defined.
[0086]
The seal member 64 located at the upper edge of the back door 24 is pressed against the lower edge of the portion 46A by the upper side 33A of the frame 33 when the back door 24 is in the closed state, Similarly, the seal member 64 positioned is pressed by the frame 33, thereby sealing between the opening 30 at the rear end of the vehicle body 10 and the back door 24.
[0087]
When the back door 24 is in the open state, the seal member 64 has a balloon shape in cross section indicated by an imaginary line in FIGS. In particular, the seal members 64 on both sides in the vehicle width direction are such that when the back door 24 is in the open state, water droplets travel along the roof 22 of the vehicle body 10 as shown by an arrow B in FIG. Even if it moves, the water droplet is prevented from falling into the passenger compartment 12 by receiving the water droplet, and at the same time, it cooperates with the portion 46A of the roof member 46 that is curved and deformed inward of the vehicle, so that the water droplet is removed from the vehicle side. To the outside of the vehicle.
[0088]
As described above, the upper edge of the plate member 35 as viewed from above the vehicle has an outer shape curved toward the rear of the vehicle between the pair of hinge members 28, and the front edge of the molding member 50 is also corresponding to the rear of the vehicle. When the back door 24 is opened to the fully open position, the lower edge of the back door 24 that is turned upside down is higher in the center of the vehicle width and goes toward both sides. The state gradually decreases.
[0089]
Accordingly, the water droplets adhering to the outer surface of the central portion in the vehicle width direction of the back door move to the lower edge of the back door 24 turned upside down when the back door 24 is opened to the fully open position. 24, it moves to both sides in the vehicle width direction along the lower edge of the vehicle 24 and falls to the ridge 66 at both sides in the vehicle width direction, so that the possibility of water drops falling into the vehicle compartment 12 can be reduced. The size of the ridge 66 at the center in the vehicle width direction can be made smaller than the size at both sides.
[0090]
In the illustrated embodiment, as described above, the size of the collar 66 may be smaller at the center in the vehicle width direction than at both sides, so that it will be understood from a comparison between FIG. 15 and FIG. As described above, the distance in the vertical direction and the front-rear direction between the chamfered portion 48 of the roof material 46 and the lower edge of the portion 46A curved and deformed inward in the vehicle gradually decreases from both sides in the vehicle width direction toward the center. Is set.
[0091]
Therefore, at least as compared with the case where the distance in the vertical direction and the front-rear direction between the chamfered portion 48 of the roof material 46 and the lower edge of the portion 46A curved and deformed inward of the vehicle is a substantially constant large value. The height of the lower edge of the portion 46A that is curved and deformed inward in the vehicle width direction can be increased at the center in the vehicle width direction. In this case, the upper limit of the rear viewable range can be increased.
[0092]
As shown in FIGS. 15 and 16, except for the region where the hinge member 28 is provided, the portions of the upper side 33A and the side 33C of the frame 33 that face the seal member 64 are slightly facing the seal member. Convex curved surface. In particular, the seal member 64 positioned at the upper edge of the back door 24 is in contact with the upper part of the inclined side surface portion of the upper side portion 33A at the center in the vehicle width direction, and the upper side at both sides in the vehicle width direction. It comes into contact with the lower part of the inclined side surface portion of the portion 33A. The seal member 64 is configured to come into contact with the bottom surface portion of the substantially planar upper side portion 33A at the position of the hinge member 28, but the bottom surface portion may also be curved.
[0093]
Therefore, compared with the case where the contact surface of the upper side portion 33A of the frame 33 with respect to the seal member 64 is a flat surface, the dimensional accuracy required for the upper side portion 33A of the frame 33 is relaxed, and a hollow extrusion having a constant cross section as shown in the figure. By plastically deforming the material into a staple shape, the upper side and both sides of the back door body 32 can be easily and inexpensively formed.
[0094]
In the third embodiment as well, the inclination angle of the first transparent plate 34, the upper edge of the back door 24 when viewed in a vertical section along the vehicle longitudinal direction at the center in the vehicle width direction, and The relationship between the length between the bent portion 35A and the length between the bent portion 35A and the lower edge of the back door 24, the vertical width Wb of the region that cannot be seen through, the driver's eyes 14A, the room mirror 26, the connection The height and the like of the member 38 are set in the same manner as in the first and second embodiments described above, and therefore the same effects as the effects of the first and second embodiments can be obtained. .
