JP 2012-144126 A

  By the way, the hinge of patent document 1 is attached to a vehicle body in the state in which the rotation part was attached to the door. In order to accurately assemble the door to which the hinge is attached to the vehicle body, it is preferable to fasten the hinge while positioning the base of the hinge on the vehicle body with a jig. In this case, the jig is pressed against the base of the hinge from a location away from the edge of the door.

  Here, the fastening portion is located in a direction away from the end edge portion of the door. Therefore, when a jig for positioning the base portion of the hinge is used, the fastening of the fastening portion is hindered by the jig. As a countermeasure, by reducing the number of fastening parts, it is possible to use the jig while avoiding the fastening parts. However, when the number of fastening parts is reduced, it is difficult to assemble the door in a stable state on the vehicle body. It is possible.

  An object of the present invention is to provide a vehicle body structure in which a door can be assembled to a vehicle body accurately and stably.

  In the invention according to claim 1, the door is rotatably supported by the vehicle body by a hinge so as to open and close an opening provided in the vehicle body, and the door has an outer surface member that forms an outer surface. The outer surface member has an extending portion extending outward from the door outer end portion, and a fastening portion for fastening the hinge to the vehicle body is provided only inside the door from the door outer end portion. It is characterized by being.

  According to a second aspect of the present invention, the vehicle body has a tailgate opening, the tailgate opening has a gate support shaft in a horizontal direction, and the tailgate opening is opened and closed by rotating about the gate support shaft. The door includes a tailgate, the door is provided on the tailgate via the hinge, the hinge includes a door support shaft in a direction orthogonal to the gate support shaft, and the fastening portion is the gate. It is characterized in that a plurality are provided at intervals in a direction orthogonal to the support shaft.

  According to a third aspect of the present invention, the fastening portion includes a fastening member fixed to the vehicle exterior side of the hinge and a member to be fastened to the fastening member from the vehicle interior side of the hinge.

  According to a fourth aspect of the present invention, the garnish is provided on the vehicle body so as to form an outer surface of the vehicle body, and the garnish is formed so as to cover a vehicle outer side of the extension portion.

  According to a fifth aspect of the present invention, the garnish has a leg portion extending in an in-vehicle direction, and the leg portion is attached to a hinge.

  According to a sixth aspect of the present invention, in the leg portion, both one and the other of the hinge are attached to the vehicle body in a direction orthogonal to the gate support shaft.

  According to a seventh aspect of the present invention, the extending portion is provided symmetrically with respect to the extending shaft, with the extending direction of the extending portion serving as an extending shaft.

In the invention which concerns on Claim 1, it has the extension part in the hinge and extended the extension part to the door outward rather than the door outer end part of the outer surface member. Further, the fastening portion is fastened only from the door outer end to the door inner side. Therefore, it is possible to avoid the fastening portion and press the extending portion with the jig.
Thereby, since a fastening part can be fastened in the state which pressed down an extension part with a jig, a door can be assembled to a vehicle body with sufficient accuracy.
Furthermore, it is not necessary to reduce the number of fastening parts by avoiding the fastening parts and pressing the extension part with a jig. As a result, the door can be assembled to the vehicle body in a stable state.

Here, for example, by avoiding the extension part and fastening the fastening part outward from the door outer end part, the fastening part can be fastened with the extension part pressed by a jig. is there. However, when the fastening portion is fastened outward from the door outer end, the hinge becomes large.
On the other hand, as in claim 1, the hinge can be made compact by fastening the fastening portion only inside the door from the door outer end portion.

  In the invention according to claim 2, the gate support shaft is provided in the horizontal direction at the tailgate opening, and the tailgate is rotated about the gate support shaft. That is, the tailgate is opened and closed in the vertical direction about the gate support shaft. This tailgate is provided with a door. Therefore, when the tailgate is opened and closed, the door rotates in the vertical direction together with the tailgate.

  For this reason, the load of the direction orthogonal to a gate spindle acts on the fastening part of a hinge. Therefore, a plurality of hinge fastening portions are provided at intervals in a direction orthogonal to the gate spindle. As a result, when the tailgate is opened and closed in the vertical direction, the load generated by the opening and closing can be suitably supported by the plurality of fastening portions, and the door can be securely held on the tailgate.

In the invention which concerns on Claim 3, the fastening member of the fastening part was fixed to the vehicle outer side of the hinge, and the to-be-fastened member was fastened to the fastening member from the vehicle inner side of the hinge. Therefore, the work space for performing the fastening work on the vehicle exterior side of the hinge can be eliminated.
This eliminates the need for a work hole or the like for inserting a fastening tool (such as an impact wrench) on the vehicle outer side than the fastening member, and allows a simple configuration.

  In the invention according to claim 4, the garnish is provided on the vehicle body, and the outer surface of the vehicle body is formed by the garnish. Furthermore, the extension part was covered from the vehicle outer side with garnish. Thereby, since the extension part can be concealed by garnish, the appearance of the vehicle body can be ensured satisfactorily.

In the invention which concerns on Claim 5, the leg part was extended toward the vehicle interior direction from the garnish, and the leg part was attached to the hinge. Therefore, a leg part can be formed in the edge part by the side of the hinge of a garnish.
Here, by extending the legs from the garnish toward the interior of the vehicle, sinking may occur in a portion corresponding to the legs on the outer surface of the garnish when the garnish is molded. Therefore, the leg is formed at the end on the hinge side.

  Therefore, for example, even when sink marks occur in a portion corresponding to the leg portion on the outer surface of the garnish, the sink marks can be adjacent to the end portion (that is, the end edge) on the hinge side. Thereby, compared with the case where sink marks are formed away from the end portion on the hinge side, sink marks on the outer surface can be made inconspicuous, and the appearance of the garnish can be kept good.

  Furthermore, the leg portion was extended toward the interior of the vehicle, and the leg portion was attached to the hinge. Therefore, the distance between the garnish and the vehicle body in the in-vehicle direction can be kept constant, and deterioration of the appearance of the garnish can be further suppressed.

In the invention which concerns on Claim 6, a leg part was attached to the vehicle body in both one and the other of hinges. Therefore, the leg portion can be attached to the vehicle body side over a wide range in the direction orthogonal to the gate support shaft.
Thereby, it can control with a leg part that a garnish shifts in the direction which intersects perpendicularly to a gate spindle.

In the invention which concerns on Claim 7, the fastening part was provided symmetrically with respect to the extension axis | shaft by making the extension direction of the extension part into the extension axis | shaft.
Here, it is conceivable that the fastening portion is not provided symmetrically with respect to the extending axis. In this case, when the door is opened, it is conceivable that the load acts on the fastening portion provided on one side of the extension shaft and the fastening portion provided on the other side of the extension shaft.

Therefore, the extending direction of the extending part is used as an extending axis, and the fastening part is provided symmetrically with respect to the extending axis. Therefore, when the door is opened, a load can be applied so as not to be biased between the fastening portion provided on one side of the extension shaft and the fastening portion provided on the other side of the extension shaft.
Thereby, the load generated when the door is opened can be received evenly in a balanced manner at each fastening portion.

On the other hand, the tailgate 15 is arranged substantially vertically by closing the tailgate 15 downward. In this state, the tailgate opening 13 is closed by the tailgate 15.

  Returning to FIG. 3, the right edge 30 a of the sub door 30 is rotatably supported by the right side 23 of the gate body 16 (that is, the door opening 22) by the upper door hinge 24 and the lower door hinge 25. Therefore, the open end (that is, the left edge) 30b of the sub door 30 can be opened horizontally in the direction of the vehicle exterior 29 with respect to the gate body 16.

As described above, the sub door 30 rotates in the horizontal direction around the upper door hinge 24 and the lower door hinge 25, so that the door opening 22 is opened and closed by the sub door 30.
The sub door 30 includes a door body 31 that is rotatably supported on the right side 23 of the gate body 16 via an upper door hinge 24 and a lower door hinge 25, and a door window glass 32 provided on the upper portion of the door body 31. ing.

As shown in FIGS. 4 and 5, the door body 31 includes a metal inner panel 34 provided on the vehicle interior 28 side, a metal outer panel 37 provided on the vehicle exterior 29 side from the inner panel 34, and an outer panel 37. And a resin-made design member 41 (see FIG. 1) provided on the vehicle exterior 29 side from the lower half of the vehicle.
Further, an upper outer surface member (outer surface member) 38 is formed in the upper half portion of the outer panel 37.
The outer surface of the sub door 30 is formed by the surface of the upper / outer surface member 38 and the surface of the design member 41.

  Hereinafter, in order to facilitate understanding of the configuration of the subdoor 30, the upper half of the outer panel 37 is the upper outer surface member 38, the lower half of the outer panel 37 is the lower outer panel 39, and the upper half of the inner panel 34 is the upper inner panel 35. The lower half of the inner panel 34 will be described as the lower inner panel 36.

As shown in FIG. 4, the hinge side end portion 35a of the upper inner panel 35 and the hinge side end portion (door outer end portion) 38a of the upper outer surface member 38 are crimped by hemming molding. Thereby, the hinge side end portion 35a of the upper inner panel 35 is joined in a state covered with the hinge side end portion 38a of the upper and outer surface member 38.
An end wall portion 35 b is formed adjacent to the hinge side end portion 35 a of the upper inner panel 35, and the end wall portion 35 b is supported by the center 23 a of the right side portion 23 of the gate body 16 via the upper door hinge 24.
The upper / outer surface member 38 is formed flat, and the upper / outer surface member 38 forms the upper door outer surface 38b of the upper half of the door body 31.

An end portion 38c on the upper door hinge 24 side of the upper door outer surface 38b is separated from the door side end portion 18a of the upper gate outer surface member 18 by an interval S1 with an upper separating portion (separating portion) 43 therebetween. Further, the hinge side end portion 38a of the upper and outer surface member 38 is formed in a stepped shape so as to be recessed toward the vehicle interior 28 side with respect to the upper door outer surface 38b.
The hinge-side end portion 38a formed in a step shape is arranged so as to overlap the door-side end portion 18a of the upper gate outer surface member 18 in the vehicle interior / exterior direction (arrow CD direction). As a result, the upper separation portion 43 between the upper outer surface member 38 and the upper gate outer surface member 18 is covered with the hinge side end portion 38 a of the upper outer surface member 38.

  As shown in FIG. 5, the hinge side end (outer surface member side end) 36a of the lower inner panel 36 and the hinge side end (outer surface member side end) 39a of the lower outer panel 39 are crimped by hemming. . As a result, the hinge side end portion 36 a of the lower inner panel 36 is joined in a state covered with the hinge side end portion 39 a of the lower outer panel 39.

The lower inner panel 36 is formed with an end wall portion 36b adjacent to the hinge side end portion 36a. Further, the end wall portion 36 b is supported by the lower portion 23 b of the right side portion 23 of the tailgate 15 via the lower door hinge 25.
A lower door outer surface 41a of the lower half of the door body 31 is formed of a resin design member 41. The lower door outer surface 41a and the upper door outer surface 38b form the door outer surface of the door body 31.

As shown in FIGS. 4 and 6, the upper door hinge 24 includes a fixed portion 45 attached to the center 23 a of the right side portion 23 of the tailgate 15, a hinge extending portion 46 extending from the fixed portion 45, and a fixed portion 45. Are attached to the center 23a of the right side portion 23, a door support shaft 48 that pivotally connects the rotating portion 49 to the fixed portion 45, and a plurality of bolts on the end wall portion 35b of the door body 31. And a rotating part 49 attached with a nut (not shown).
The door support shaft 48 of the upper door hinge 24 is disposed in a direction orthogonal to the gate support shaft 14 (see FIG. 1) of the tailgate 15.

The fastening portion 47 includes a stud bolt (fastening member) 54 that is fixed to the outside 29 of the fixing portion 45, and a nut (fastened member) 55 that is fastened to the screw portion 54 a of the stud bolt 54.
The upper door hinge 24 is attached to the door body 31 with a plurality of bolts and nuts, and the fixing portion 45 of the upper door hinge 24 is disposed at the center 23 a of the right side portion 23. In this state, the nut 55 is fastened to the threaded portion 54a of the stud bolt 54 from the interior 28 side of the fixed portion 45, whereby the upper door hinge 24 is attached to the center 23a of the right side portion 23 with a plurality of fastening portions 47.

Thus, the stud bolt 54 is fixed to the outside 29 side of the fixing portion 45, and the nut 55 is fastened to the threaded portion 54a of the stud bolt 54 from the inside 28 side of the fixing portion 45. Therefore, the work space for performing the fastening work on the outside 29 side of the fixed portion 45 (that is, the upper door hinge 24) can be eliminated.
Accordingly, it is not necessary to provide a work hole or the like for inserting a fastening tool (impact wrench or the like) on the vehicle exterior 29 side (that is, the upper / outer surface member 38 side) with respect to the stud bolt 54, and a simple configuration can be achieved. .

In addition, a plurality of fastening portions 47 are provided (offset) at intervals S2 in a direction orthogonal to the gate spindle 14 (see FIG. 1).
Here, by providing the plurality of gate support shafts 14 in the horizontal direction, the tail gate 15 is opened and closed so as to be rotatable in the vertical direction about the plurality of gate support shafts 14. A sub door 30 is provided on the gate body 16 of the tailgate 15. Therefore, when the tailgate 15 is opened and closed, the sub door 30 is also rotated in the vertical direction together with the tailgate 15.

For this reason, the load F <b> 1 in the direction orthogonal to the gate spindle 14 acts on the plurality of fastening portions 47 of the upper door hinge 24. Therefore, a plurality of fastening portions 47 are provided at intervals S2 in a direction perpendicular to the gate spindle 14.
As a result, when the tailgate 15 is opened and closed in the vertical direction, the load F1 generated by the opening and closing can be suitably supported by the plurality of fastening portions 47, and the subdoor 30 can be reliably held on the gate body 16 of the tailgate.

By the way, the plurality of fastening portions 47 are provided symmetrically with respect to the extending shaft 57. The extending shaft 57 is a shaft that extends in the extending direction of the hinge extending portion 46 at the center in the width direction of the hinge extending portion 46.
Here, it is also conceivable that the plurality of fastening portions 47 are not provided symmetrically with respect to the extension shaft 57. In this case, it is considered that when the sub door 30 is opened, the load acts on the fastening portion 47 provided on one side of the extension shaft 57 and the fastening portion 47 provided on the other side of the extension shaft 57 in an uneven manner. It is done.

Therefore, the plurality of fastening portions 47 are provided symmetrically with respect to the extension shaft 57. Therefore, when the sub door 30 is opened, the load F2 is applied so as not to be biased between the fastening portion 47 provided on one side of the extension shaft 57 and the fastening portion 47 provided on the other side of the extension shaft 57. Can do.
Thereby, the load F2 generated when the sub door 30 is opened can be received by each fastening portion 47 evenly in a well-balanced manner.

The hinge extension 46 extends from the end 45a of the fixed part 45 outward (in the direction of arrow B) of the door. By extending the hinge extending portion 46 outward from the door, the hinge extending portion 46 extends outward from the hinge side end 38a of the upper and outer surface member 38.
Further, the plurality of fastening portions 47 are provided only inward of the door (in the direction of arrow A) from the hinge side end portion 38 a of the upper and outer surface members 38.

Therefore, as shown in FIG. 7, it is possible to avoid the plurality of fastening portions 47 (specifically, stud bolts 54) and press the hinge extension portion 46 with the jig 59 (indicated by an imaginary line). As a result, a plurality of fastening portions 47 (specifically, nuts 55) can be fastened with the hinge extension portion 46 pressed by the jig 59, so that the sub door 30 can be assembled to the tailgate 15 with high accuracy. .
Furthermore, it is not necessary to reduce the number of fastening portions 47 by avoiding the plurality of fastening portions 47 and pressing the hinge extending portions 46 with the jig 59. As a result, the sub door 30 can be assembled to the tailgate 15 in a stable state.

  Here, for example, a plurality of fastening portions 47 are fastened by avoiding the hinge extending portions 46 from the hinge side end portions 38a of the upper and outer surface members 38 to the outside of the door (in the direction of arrow B). It is possible to fasten a plurality of fastening portions 47 in a state of being pressed by the jig 59.

However, when the plurality of fastening portions 47 are fastened outward from the hinge-side end portion 38a of the upper / outer surface member 38, the fixing portion 45 protrudes greatly outward from the hinge-side end portion 38a, and the upper door hinge 24 is It will become large.
Therefore, the plurality of fastening portions 47 are fastened only from the hinge side end portion 38a of the upper / outer surface member 38 to the inside of the door. Thereby, the overhang | projection to the door outward of the fixing | fixed part 45 can be suppressed, and the upper door hinge 24 can be made compact.

  Further, as shown in FIG. 4, the vehicle exterior 29 side of the hinge extension 46 is covered with the door side end 18 a of the upper gate outer surface member 18. The upper gate outer surface member 18 is a resin member that forms the outer surface of the gate body 16. By covering the hinge extension portion 46 with the door-side end portion 18a, the hinge extension portion 46 can be hidden by the upper gate outer surface member 18, so that the appearance of the vehicle body can be ensured satisfactorily.

  Furthermore, the upper gate outer surface member 18 has a leg portion 61 on the back surface 18b of the door side end portion 18a. The leg portion 61 extends from the back surface 18b of the door side end portion 18a toward the in-vehicle direction (arrow C direction), and the distal end portion 61a is attached to the hinge extension portion 46. Specifically, the tip 61a is bonded to the hinge extension 46 with an adhesive 63 (see FIG. 8).

  Here, when the upper gate outer surface member 18 is formed by forming the leg portions 61 on the back surface 18b of the upper gate outer surface member 18, it corresponds to the leg portion 61 of the outer surface 18c of the upper gate outer surface member 18. It is conceivable that sink marks occur at the site. Therefore, the leg portion 61 is formed on the door side end portion 18a (that is, the end portion on the upper door hinge 24 side).

  Therefore, for example, even when a sink mark is generated in a portion corresponding to the leg portion 61 of the outer surface 18c, the sink mark can be adjacent to the door side end portion 18a (that is, the edge). Thereby, compared with the case where sink marks are formed away from the door-side end portion 18a, sink marks on the outer surface 18c can be made inconspicuous, and the appearance of the upper gate outer surface member 18 can be kept good.

  Further, by attaching the distal end portion 61a of the leg portion 61 to the hinge extending portion 46, the distance S3 between the upper gate outer surface member 18 and the gate body 16 in the in-vehicle outward direction (arrow CD direction) can be kept constant. The appearance of the upper gate outer surface member 18 can be kept better.

  In addition, as shown in FIG. 8, the tip 61a of the leg 61 is located on one side of the hinge extension 46 in the direction (arrow E direction) orthogonal to the gate support shaft 14 (see FIG. 1). It has a part (one) 61b and a part (the other) 61c on the other side. Both the one side portion 61 b and the other side portion 61 c are attached to the center 23 a of the right side portion 23 of the gate body 16.

  Therefore, the front end portion 61 a of the leg portion 61 can be attached across the hinge extension portion 46 and the right side portion 23 in the direction orthogonal to the gate support shaft 14. Thereby, it is possible to restrict the upper gate outer surface member 18 from being displaced in a direction orthogonal to the gate support shaft 14 by the leg portion 61.

As shown in FIG. 9, the lower door hinge 25 is a member similar to the upper door hinge 24. The lower door hinge 25 includes a fixing portion 65 attached to the lower portion 23b of the right side portion 23 of the tailgate 15, a hinge extension portion 66 extending from the fixing portion 65, and a plurality of attachment portions 65 attached to the lower portion 23b of the right side portion 23. A fastening portion 67, a door support shaft 68 that rotatably connects the rotating portion 69 to the fixed portion 65, and a rotating portion 69 that is attached to the sub door 30 with a plurality of bolts and nuts.
The fastening portion 67 has the same configuration as the fastening portion 47 (see FIG. 4) of the upper door hinge 24, and the same reference numerals as those of the fastening portion 47 are given to the respective constituent members, and detailed description thereof is omitted.

As shown in FIGS. 9 and 10, in order to avoid the lower door hinge 25, the hinge-side end portion 36 a of the lower inner panel 36 and the hinge-side end portion 39 a of the lower outer panel 39 are inflated at locations corresponding to the lower door hinge 25. A protruding portion 74 is formed. The bulging portion 74 is bulged out 29 toward the outside of the vehicle.
In the state where the tailgate 15 is closed, the bulging portion 74 is a flat top portion 75 disposed on the vehicle exterior 29 side of the lower door hinge 25 and an upper portion extended downward from the upper end 75a of the top portion 75. It has an inclined portion 76 and a lower inclined portion 77 that extends downward from the lower end 75b of the top portion 75 toward a downward slope.

The upper inclined portion 76 is an upper outward extending portion (outward extending portion) that extends outward (in the direction of arrow B) from the rotation center 79 of the lower door hinge 25 (that is, the center of the door support shaft 68). ) 76a. Furthermore, the upper / outward extending portion 76a extends so as to extend in the in-vehicle direction (arrow C direction) as it extends outward from the door.
The lower inclined portion 77 has a lower outward extending portion (outward extending portion) 77 a that extends outward from the rotation center 79 of the lower door hinge 25. Furthermore, the lower outward extending portion 77a extends toward the in-vehicle direction as it extends outward from the door.

That is, the upper / outward extending portion 76a and the lower / outward extending portion 77a are extended outward from the door and bent in the vehicle interior / exit direction.
As a result, the outer panel 37 and the inner panel 34 are moved in the vertical direction (that is, with respect to the gate support shaft 14 (see FIG. 1)) at the upper and outer extending portions 76a and the lower and outer extending portions 77a (that is, the bulging portions 74). Thus, the rigidity in the direction of the arrow E orthogonal to the direction of the inside and outside of the vehicle (the direction of the arrow CD) is enhanced.

As shown in FIG. 10, the hinge side end 39a of the lower outer panel 39 of the sub door 30 is located on the vehicle exterior 29 side of the lower door hinge 25, and is inward of the door by a distance L1 from the rotation center 79 of the lower door hinge 25. (Arrow A direction).
Therefore, compared to the case where the hinge-side end 39a of the lower outer panel 39 is positioned outward of the door (in the direction of arrow B) from the rotation center 79 of the lower door hinge 25, the hinge-side end 39a is more open when the sub door 30 is opened. The distance that wraps around the vehicle 28 can be reduced.
Thereby, interference with the lower door hinge 25 (especially fixing | fixed part 65) and the hinge side edge part 39a is prevented, and the subdoor 30 can be opened largely in the arrow direction. Furthermore, since the space 82 in the vicinity of the rotation center 79 can be secured widely, the degree of freedom in designing the hinge layout is improved.

  Further, as shown in FIG. 5, an attachment hole 39 b (attachment part) is formed in the lower outer panel 39, and the attachment hole 39 b is arranged on the vehicle interior 28 side with respect to the rotation center 79 of the lower door hinge 25. The reason why the mounting hole 39b is arranged on the vehicle interior 28 side of the rotation center 79 of the lower door hinge 25 will be described in detail later.

Further, the hinge-side end portion (end portion on the outer surface member side) 41 b of the design member 41 of the sub door 30 and the design member-side end portion 19 a of the lower gate outer surface member 19 are interposed via a lower separation portion (separation portion) 83. They are separated by an interval S4.
The hinge side end 41b of the design member 41 is a right edge on the opposite side of the lower end outer surface 41a of the design member 41 from the open end 30b (see FIG. 1) in the door width direction (arrow AB direction). 30a (see FIG. 1).

The design member side end portion 19 a of the lower gate outer surface member 19 is an end portion of the outer surface 19 b of the lower gate outer surface member 19 that faces the hinge side end portion 41 b of the design member 41.
The outer surface 19b of the lower gate outer surface member 19 and the lower door outer surface 41a of the design member 41 are disposed substantially flush with each other. The design member 41 has a design extension portion (extension portion) 85 formed on the hinge side end portion 41b.

  The design extension portion 85 extends from the hinge side end portion 41b of the lower door outer surface 41a of the design member 41 toward the lower gate outer surface member 19 and in the in-vehicle direction (arrow C direction). As a result, the lower separation portion 83 between the lower gate outer surface member 19 and the design member 41 can be hidden by the design extension portion 85, so there is no possibility that the inside of the vehicle body structure is visually recognized from the vehicle exterior 29 side.

Here, the design member 41 is a resin member. That is, even when the design member 41 slightly interferes with the lower door hinge 25 (that is, the fixed portion 65), the plastic deformation of the design member 41 can be suppressed as compared with the case where the metal outer panel interferes with the lower hinge. .
Therefore, even when the design member 41 slightly interferes with the lower door hinge 25, it is possible to prevent the design member 41 (that is, the sub door 30) from being damaged. Thereby, the hinge side end 41b and the design extension 85 of the design member 41 can be extended from the hinge side end 39a of the lower outer panel 39 to the lower gate outer surface member 19 side, and the appearance of the vehicle body 11 is good. Can be secured.

  The design extension 85 extends from the hinge-side end 41b of the design member 41 in the in-vehicle direction (arrow C direction) and from the tip 86a of the vertical extension 86 to the lower gate outer surface member 19. And a lateral extension 87 extending in the direction.

The lateral extension 87 is disposed on the interior 28 side of the design member side end 19a of the lower gate outer surface member 19, and is disposed so as to overlap the design member side end 19a in the interior / exterior direction (arrow CD direction). Has been.
Thereby, the lower separation part 83 between the lower gate outer surface member 19 and the design member 41 can be covered more favorably with the design extension part 85, and the appearance of the vehicle body 11 can be further ensured.

Further, the lateral extension 87 is continued in the vertical direction (that is, the direction of arrow E shown in FIG. 9) orthogonal to both the inside / outside direction of the door (arrow A-B direction) and the inside / outside direction of the vehicle (arrow CD direction). ing. That is, the laterally extending portion 87 is continued in the vertical direction along the upper separating portion 43.
Thereby, it is possible to prevent the internal structure of the vehicle body structure 10 from being viewed from the outside 29 side in a region continuous in the vertical direction.

Furthermore, the hinge side end 39a of the lower outer panel 39 is positioned inward (arrow A direction) in the door inner and outer direction than the hinge side end 41b of the design member 41.
Therefore, the hinge side end 39a of the lower outer panel 39 can be separated from the design extension 85. Thereby, it can prevent that the design extension part 85 and the hinge side edge part 39a of the lower outer panel 39 interfere.

  Returning to FIG. 5, the design member 41 is attached to the attachment hole 39 b of the lower outer panel 39 by a clip (connecting means) 91. Specifically, a pedestal 92 is formed in a portion 41 d of the back surface 41 c of the design member 41 that faces the mounting hole 39 b of the lower outer panel 39. The head portion 91 a of the clip 91 is connected to the pedestal 92, and the clip portion 91 b of the clip 91 is locked in the mounting hole 39 b of the lower outer panel 39.

Here, the mounting hole 39 b of the lower outer panel 39 is disposed on the vehicle interior 28 side of the rotation center 79 of the lower door hinge 25. Therefore, the clip 91 is disposed at a position away from the lower door hinge 25 toward the interior 28 side. The attachment hole 39b of the lower outer panel 39 can be separated from the design member 41 in the in-vehicle direction (arrow C direction) by the distance from the lower door hinge 25.
As a result, a space 94 is secured between the design member 41 and the outer panel in the vehicle interior / exterior direction (arrow CD direction). Therefore, the space 94 for accommodating the base 92 for the clip 91 can be easily secured.
