Description

  The present invention relates to a vehicle body structure with a tailgate in which an opening (rear opening) is provided at a rear portion of a vehicle body, and a tailgate is supported on an upper portion of the rear opening so as to be rotatable in the vertical direction.

  As a vehicle body structure with a tailgate, a rear opening (main opening) is provided at the rear of the vehicle body, a tailgate is provided at the top of the rear opening so that it can be opened and closed vertically, and a door opening (sub-opening) is provided at the tailgate. In addition, there is known one in which left and right auxiliary doors are provided at the door opening so as to be openable and closable in the lateral direction (vehicle width direction) (for example, see Patent Document 1).

  In this vehicle body structure, the left and right auxiliary doors are opened outward in the vehicle width direction from the center of the vehicle body. That is, the left auxiliary door is disposed adjacent to the left frame portion side of the tailgate with the left auxiliary door open. Further, the right auxiliary door is disposed adjacent to the right frame portion side of the tailgate in a state where the right auxiliary door is opened.

It is conceivable that these left and right sub doors are provided with electrical components. Since the left and right auxiliary doors are opened from the center of the vehicle body to the outside in the vehicle width direction, it is possible to guide the wire harness from the left frame portion and the right frame portion of the tailgate to each auxiliary door.
The wire harness led to each sub door is connected to the electrical component through each sub door.

Utility Model Registration No. 2514650

  Here, in the vehicle body structure of Patent Document 1, the left and right auxiliary doors are opened from the center of the vehicle body to the outside in the vehicle width direction. Therefore, the opened left and right auxiliary doors are arranged outside in the vehicle width direction. For this reason, when getting on and off from the outside in the vehicle width direction, the left auxiliary door and the right auxiliary door on the outside in the vehicle width direction become an obstacle.

As a countermeasure against this, it is conceivable to support the auxiliary door in a freely openable manner via a hinge on the center side of the tailgate in the vehicle width direction. Thereby, it becomes possible to open a subdoor from the vehicle width direction outer side of a tailgate.
In this case, it is preferable that the wire harness is led from the center side in the vehicle width direction of the tailgate (that is, the hinge side) to the secondary door, and the led wire harness is connected to the electrical components of the secondary door.

By the way, in a normal vehicle, a seal member for sealing between the vehicle body and the door is provided on the vehicle compartment side from the wire harness. Therefore, in the area where the wire harness is routed, the seal member is disposed in a recessed state on the vehicle compartment side.
When this seal member is applied to the tailgate, rainwater collects in the recessed portion of the seal member when the tailgate is opened in the rain. For this reason, when closing the tailgate, it is conceivable that the accumulated rainwater is guided downward and falls on the operator of the tailgate.

  An object of the present invention is to provide a vehicle body structure with a tailgate that can make it difficult to collect rainwater when the tailgate is opened in rainy weather.

  According to a first aspect of the present invention, there is provided a vehicle body with a tailgate provided with a tailgate supported by the vehicle body at an upper portion of the opening so as to open and close an opening provided at a rear portion of the vehicle body in a vertical direction. The tailgate is provided with a sub-opening that opens to the tailgate and communicates with the opening, and a sub-door that opens and closes the sub-opening. A separation portion that is separated from the outer surface of the door by a predetermined distance is provided, and either the gate body of the tailgate or the sub door faces the separation portion, and the tailgate A surface portion extending forward of the vehicle body in a closed state is provided, and the surface portion is provided with a harness hole for inserting a harness routed from the gate body to the sub door, and among the surface portions, Harness hole The site after positioned toward the rear of the vehicle body, the seal member for sealing between said gate body and the sub door is being arranged.

  According to a second aspect of the present invention, a door checker that holds the sub door in an open position is interposed between the sub door and the surface portion, and the seal member is disposed behind the door checker in a vehicle body. .

  According to a third aspect of the present invention, the surface portion is formed in a planar shape toward the vehicle body front-rear direction with the tailgate closed, and extends in the vehicle width direction from the plane portion provided with the harness hole. A second surface portion, a third surface portion extending from the second surface portion toward the rear of the vehicle body, and a fourth surface portion extending from the third surface portion in the vehicle width direction, the third surface portion and the third surface portion A square-shaped part is formed in the rear part in the four surface parts, and the sealing member is arranged in the square-shaped part.

  According to a fourth aspect of the present invention, the seal member is disposed along the sub-opening over the entire periphery of the sub-opening.

  According to a fifth aspect of the present invention, a closed cross section is formed by the square-shaped portion.

  According to a sixth aspect of the present invention, the gate main body of the tailgate is provided with an outer handle for operating locking / unlocking of the tailgate, and the sub-door is connected with the harness inserted through the harness hole. A door harness hole for leading into the door is provided, and the door harness hole, the outer handle, and the harness hole are provided in this order from the top in the vertical direction.

In the invention which concerns on Claim 1, the surface part was provided in the outer surface of any one of a tailgate or a subdoor, and the harness hole was provided in the surface part. A harness routed from the gate body to the sub door is inserted into the harness hole.
Further, the rear portion of the surface portion is formed behind the harness hole in the vehicle body, and the seal member is arranged at the rear portion.

Therefore, the seal member can be arranged behind the harness hole (that is, the harness) in the vehicle body, and the seal member can be prevented from being recessed toward the vehicle compartment. Thereby, when the tailgate is opened in rainy weather, it is possible to make it difficult to collect rainwater that has entered from the space between the sub door and the gate body.
By making rainwater difficult to collect, when the operator closes the tailgate, it is possible to prevent rainwater from splashing from the lower end of the tailgate and prevent the rainwater from falling on the operator.

Furthermore, by disposing the seal member at the rear of the harness hole in the vehicle body, it is possible to prevent rainwater entering from the separated portion from entering the harness hole when the tailgate is opened.
Thereby, rainwater can be prevented from entering the tail gate (specifically, either the gate body or the sub door) from the harness hole.

In the invention according to claim 2, the seal member is arranged behind the door checker in the vehicle body. Therefore, it is possible to prevent the door checker from being flooded with rainwater or the like.
Thereby, for example, it is possible to prevent rainwater or the like attached to the door checker from freezing and hindering the opening and closing of the sub door.

  In the invention which concerns on Claim 3, the rear part of the surface part was formed in the square shape part, and the sealing member was arrange | positioned in the square shape part. Therefore, the contact area where the seal member contacts the square portion can be reduced. Thereby, the pressing force with respect to the square-shaped part of a sealing member can be raised, and the sealing performance between a sealing member and a square-shaped part can be improved.

Furthermore, the second surface portion can be interposed between the square shape portion and the plane portion by forming the square shape portion with the third surface portion and the fourth surface portion. Therefore, by absorbing the manufacturing tolerance (molding tolerance) at the second surface portion, it is possible to further increase the molding accuracy of the flat surface portion in a state where the molding accuracy of the square-shaped portion is increased.
Thereby, the shaping | molding precision (position precision) of the harness hole formed in a plane part can be ensured, and the harness inserted in the harness hole can be routed with sufficient precision.

  In the invention which concerns on Claim 4, the sealing member was arrange | positioned along the subopening over the perimeter periphery of the subopening. Thereby, it is possible to prevent rainwater from entering the harness hole from the entire circumference of the sub-opening.

In the invention according to claim 5, the closed cross section is formed by the square-shaped portion. The square-shaped portion is formed into a square-shaped portion at the third surface portion and the fourth surface portion. For example, when this square-shaped portion is formed in front of the harness hole in the vehicle body, the closed cross section formed by the square-shaped portion is small. For this reason, it is difficult to ensure the rigidity of the gate body.
Here, a seal member is arranged behind the harness hole in the vehicle body. Therefore, the rectangular portion can be arranged behind the harness hole in the vehicle body. Thereby, the closed cross section formed by the square-shaped portion can be enlarged, and the rigidity of the gate body can be secured.

In the invention according to claim 6, the outer handle is provided in the gate body, and the door harness hole is provided in the sub door. A door harness hole is a hole which guides the harness extended from the harness hole in a subdoor.
Here, the outer handle is configured such that the operator inserts his / her hand inside the outer handle (that is, on the gate body side) to operate locking / unlocking. Therefore, the outer surface of the portion of the gate body where the outer handle is provided is formed in a concave shape, and the thickness dimension is reduced.
On the other hand, since the door harness hole and the harness hole need to be passed through the harness, the opening size becomes large. For this reason, it is difficult to form a door harness hole or a harness hole in a portion where the outer handle is provided and the thickness dimension is reduced.

Therefore, the door harness hole, the outer handle, and the harness hole are provided in this order from the top in the vertical direction. Therefore, the door harness hole and the harness hole can be shifted in the vertical direction from the outer handle.
As a result, the door harness hole and the outer handle can be provided without causing the tailgate to bulge rearward of the vehicle body.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. Note that “front (Fr)”, “rear (Rr)”, “left (L)”, and “right (R)” follow the direction seen from the driver.

A vehicle body structure 10 with a tailgate according to an embodiment will be described.
As shown in FIGS. 1 and 2, the vehicle body structure 10 with a tailgate includes a tailgate 15 provided at a rear portion 12 of the vehicle body 11.
The vehicle body 11 includes a rear opening frame portion 13 at a rear portion 12 of the vehicle body 11, and a tailgate 15 is supported by an upper frame portion 13 c of the rear opening frame portion 13.

The rear opening frame portion 13 is formed into a substantially rectangular frame body in the rear view by the left and right frame portions 13a and 13b, the upper frame portion 13c, and the lower frame portion 13d. A rear opening (opening) 14 is formed by the rear opening frame portion 13. The tailgate 15 is supported on the upper part of the rear opening 14 (that is, the upper frame part 13c of the rear opening frame part 13).
The passenger compartment 22 and the vehicle exterior 23 are communicated with each other through the rear opening 14, and passengers can get on and off and take in and out the luggage.

  As shown in FIG. 3, the tailgate 15 is provided on the gate body 16, and the gate body 16 is supported by the upper frame portion 13 c of the rear opening frame portion 13 so as to be rotatable in the vertical direction via a gate hinge. A gate window glass 17, a gate decoration member 18 provided below the gate window glass 17, and a sub door 20 for opening and closing the gate body 16 are provided.

As shown in FIG. 2, when the tailgate 15 is opened, the lower end 15 a of the tailgate 15 is disposed at substantially the same height as the upper end 15 b of the tailgate 15.
However, FIG. 2 shows a state in which the lower end 15a of the tailgate 15 is disposed slightly below the upper end 15b in order to facilitate understanding of the configuration.
By opening the tailgate 15, the tailgate 15 is disposed substantially horizontally at the position of the upper frame portion 13 c of the rear opening frame portion 13. In this state, the rear opening 14 of the rear opening frame 13 is opened, and the passenger compartment 22 and the vehicle exterior 23 are communicated with each other through the rear opening 14.

On the other hand, as shown in FIG. 1, when the tailgate 15 is closed, the lower end 15 a of the tailgate 15 is disposed below the upper end 15 b of the tailgate 15. That is, the tailgate 15 is disposed substantially vertically by closing the tailgate 15.
In this state, the rear opening 14 of the rear opening frame 13 is closed by the tailgate 15.

As shown in FIGS. 2 and 4, the gate body 16 is formed in a substantially rectangular shape so that the rear opening 14 of the rear opening frame 13 can be opened and closed, and the upper end 16 a is the upper frame 13 c of the rear opening frame 13. Is supported so as to be vertically rotatable via a gate hinge.
The gate body 16 is formed in a curved shape so as to bulge toward the outside 23 in the vehicle width direction.

Further, the gate main body 16 includes a window opening frame portion 26 opened substantially in the upper right half of the right side, and a door opening frame portion (periphery of the door opening) 28 opened substantially throughout the left side of the gate main body 16. .
The window inner frame 26 a of the window opening frame portion 26 and the door inner frame 28 a of the door opening frame portion 28 are also used as the partition frame 31. The partition frame 31 extends linearly in the vertical direction from the upper end 16 a to the lower end 16 b of the gate body 16.

  As shown in FIG. 5, the gate body 16 includes an inner panel 34 positioned on the vehicle compartment 22 side, an outer panel 35 positioned on the vehicle exterior 23 side, and a reinforcing member 37 interposed in a part forming the partition frame 31. Prepare.

Returning to FIG. 4, the window opening 27 is formed by forming the window opening frame portion 26 into a substantially rectangular frame.
The door opening frame portion 28 is formed in a substantially rectangular frame body, whereby a door opening (sub-opening) 29 is opened.
The window opening 27 of the window opening frame portion 26 and the door opening 29 of the door opening frame portion 28 are respectively communicated with the rear opening 14 (see FIG. 2) of the rear opening frame portion 13 with the tailgate 15 closed.

As shown in FIG. 5, the outer panel 35 includes an outer partition portion 36 that is positioned behind the inner panel 34 and that forms the outer surface of the partition frame 31.
The inner panel 34 has an inner partition portion 34 a that forms the inner surface of the partition frame 31.
The partition frame 31 is formed by overlapping an outer partition portion 36, an inner partition portion 34a, and a reinforcing member 37. By providing the reinforcing member 37 on the partition frame 31, the partition frame 31 is reinforced by the reinforcing member 37.

Therefore, as shown in FIG. 4, the partition frame 31 ensures the rigidity of the window opening frame portion 26 and the door opening frame portion 28. A gate window glass 17 is provided on the window opening frame portion 26 from the rear of the vehicle body. Further, a gate decoration member 18 is provided on the outer panel 35 (see FIG. 5) below the window opening frame portion 26 from the rear of the vehicle body.
Further, the sub door 20 is supported on the partition frame 31 of the gate body 16.

The sub door 20 includes a door main body 42 (see also FIG. 5) rotatably supported by the partition frame 31 via upper and lower door hinges 41, and a door window glass 43 provided in the upper half of the door main body 42. The door decoration member 44 provided below the door window glass 43 (that is, the lower half portion of the door main body 42) and the seal member 48 for sealing between the gate main body 16 and the sub door 20 are provided.
Here, a partition frame 31 is provided on the center side in the vehicle width direction of the gate body 16. Therefore, the sub door 20 is supported in the vehicle width direction center of the gate body 16 via the upper and lower hinges 41 so as to be freely opened.

As shown in FIG. 6, by operating the door outer handle 24 (see FIG. 3) of the sub door 20, the sub door 20 is opened in the horizontal direction (arrow A direction). Thereby, the door opening 29 of the vehicle body 11 (rear part 12) is opened.
In this state, the sub door 20 is opened from the outer side in the vehicle width direction of the tailgate 16 (the left frame portion 13a of the rear opening frame portion 13) via the upper and lower hinges 41 at the vehicle width direction center of the gate body 16. Therefore, the opened sub door 20 can be separated from the left frame portion 13a.
Thereby, when getting on and off from the left frame part 13a, the sub door 20 does not get in the way.
By closing the sub door 20, the door opening 29 is closed.

Further, as shown in FIGS. 1 and 3, the outer surface 18a of the gate decoration member 18 and the outer surface 44a of the door decoration member 44 are substantially flush with each other in the vehicle front-rear direction (when the sub door 20 is closed). It is formed substantially flush).
Further, in a state where the sub door 20 is closed, the outer surface 17a of the gate window glass 17 and the outer surface 43a of the door window glass 43 are formed on substantially the same plane (substantially flush) in the vehicle body front-rear direction.

An outer surface 19 of the tailgate 15 is formed by the outer surface 18 a of the gate decoration member 18 and the outer surface 17 a of the gate window glass 17. Further, an outer surface 45 of the sub door 20 is formed by the outer surface 44 a of the door decoration member 44 and the outer surface 43 a of the door window glass 43.
The outer surface 19 of the tailgate 15 and the outer surface 45 of the sub door 20 are formed on substantially the same surface (substantially flush) in the longitudinal direction of the vehicle body.
The outer surface 19 of the tailgate 15 and the outer surface 45 of the auxiliary door 20 form the entire outer surface 47 of the tailgate 15.

As shown in FIG. 5, there is a predetermined gap between the gate side edge 19 a on the sub door 20 side of the outer surface 19 of the tail gate 15 and the door side edge 45 a on the tail gate 15 side of the outer surface 45 of the sub door 20. A separation portion 51 is provided that is separated at a distance L1.
The separation portion 51 is disposed so as to overlap the outer partition portion 36 at the rear of the vehicle body from the outer partition portion 36 of the gate body 16 (partition frame 31) in a state where the tailgate 15 is closed.

The outer partition part 36 has an outer surface part (surface part) 55 that is disposed in front of the vehicle body of the separation part 51 and faces the separation part 51.
Here, the partition frame 31 is formed by overlapping the outer partition portion 36, the inner partition portion 34 a, and the reinforcing member 37. Therefore, a closed section 58 is formed by the outer partition portion 36 and the reinforcing member 37.

  As shown in FIGS. 7 and 8, the outer surface portion 55 is provided at a planar portion 56 formed in a planar shape in the vehicle longitudinal direction with the tailgate 15 closed, and a rear end 56 a of the planar portion 56. And a rear portion 57.

The flat portion 56 extends forward of the vehicle body with the tailgate 15 closed, and is provided with a gate harness hole (harness hole) 61. The harness 62 is passed (inserted) through the grommet through the gate harness hole 61.
By inserting the harness 62 into the gate harness hole 61, the harness 62 is routed from the inside 38 of the gate body 16 to the inside 39 of the sub door 20 (see also FIG. 12).
A rear portion 57 is located behind the gate harness hole 61 in the vehicle body.

The rear portion 57 includes a second surface portion 64 that extends to the right in the vehicle width direction from the rear end 56a of the flat portion 56, a third surface portion 65 that extends rearward from the right end 64a of the second surface portion 64, and a third surface portion. And a fourth surface portion 66 extending from the rear end 65a to the left side in the vehicle width direction.
A square portion (seal contact portion) 68 is formed in the rear portion 57 by the third surface portion 65 and the fourth surface portion 66. The rectangular portion 68 is disposed behind the gate harness hole 61 in the vehicle body. A closed section 58 is formed by the outer partition 36 having the square-shaped portion 68 and the reinforcing member 37.

Here, when the square-shaped portion 68 is disposed behind the gate harness hole 61 in the vehicle body, the square-shaped portion 68 is disposed at a position away from the left flange 37 a of the reinforcing member 37 toward the rear of the vehicle body.
Thereby, the closed section 58 can be formed larger by the square-shaped portion 68 (specifically, the outer partition 36) and the reinforcing member 37. The rigidity of the partition frame 31 (gate body 16) can be secured by increasing the closed cross section 58.

On the other hand, for example, when the square portion 68 is formed in front of the vehicle body of the gate harness hole 61, the square portion 68 is disposed in the vicinity of the left flange 37a of the reinforcing member 37. Therefore, the closed cross section 58 formed by the square portion 68 (specifically, the outer partition 36) and the reinforcing member 37 is reduced.
For this reason, it is difficult to ensure the rigidity of the partition frame 31 (gate body 16).

Further, the sealing member 48 is brought into contact with the rectangular portion 68 formed by the third surface portion 65 and the fourth surface portion 66. Therefore, compared with the case where the seal member 48 abuts on the flat surface, the contact area where the seal member 48 abuts (contacts) the square-shaped portion 68 can be reduced.
Thereby, the pressing force with respect to the square-shaped part 68 of the seal member 48 can be raised, and the sealing performance between the seal member 48 and the square-shaped part 68 can be improved.

In addition, by forming the square-shaped portion 68 with the third surface portion 65 and the fourth surface portion 66, the second surface portion 64 can be interposed between the square-shaped portion 68 and the flat surface portion 56. Therefore, the manufacturing tolerance (molding tolerance) can be absorbed by the second surface portion 64.
By absorbing the molding tolerance by the second surface portion 64, it is possible to further increase the molding accuracy of the flat surface portion 56 in a state where the molding accuracy of the square-shaped portion 68 is increased. Thereby, the shaping | molding precision (position precision) of the gate harness hole 61 formed in the plane part 56 can be ensured, and the harness 62 inserted in the gate harness hole 61 can be routed accurately.

As shown in FIGS. 4 and 8, the seal member 48 is formed in an endless substantially rectangular frame, and is attached by a plurality of clips 71 along the entire outer peripheral edge 42 a of the sub door 20 (door body 42).
Therefore, in a state where the door opening 29 is closed by the sub door 20, the seal member 48 is brought into contact with the entire circumference of the door opening frame portion 28 along the door opening 29. The door opening frame portion 28 includes a door inner frame 28a, and the door inner frame 28a includes an outer surface portion 55.
When the seal member 48 is brought into contact with the entire periphery of the door opening frame portion 28, rainwater or the like can be prevented from entering the gate harness hole 61 from the entire periphery of the door opening 29.

Here, it is conceivable that a recess toward the passenger compartment 22 is formed in a portion of the seal member 48 that faces the separation portion 51. In this state, as shown in FIG. 2, when the tailgate 15 is opened in the rain, rainwater that has passed through the separating portion 51 accumulates in the recess of the seal member 48.
When the tail gate 15 is closed, the accumulated water is guided along the seal member 48 to the lower side of the tail gate 15, and it is considered that the water splashes vigorously from the lower end 15 a of the tail gate 15.

  Therefore, as shown in FIGS. 9 and 10, the portion 48 a corresponding to the gate harness hole 61 in the seal member 48 is arranged behind the vehicle body of the gate harness hole 61 and the harness 62. Therefore, it can suppress that the sealing member 48 (especially site | part 48a) dents in the compartment 22 side.

  Thereby, when the tailgate 15 is opened in rainy weather, rainwater that has entered from the separation portion 51 between the sub door 20 and the gate body 16 can be hardly accumulated. By making it difficult to collect rainwater, when the operator closes the tailgate 15, it is possible to prevent rainwater from splashing from the lower end 15 a (see FIG. 2) of the tailgate 15 and to prevent the rainwater from falling on the operator.

As shown in FIG. 11, a door checker 75 is interposed between the sub door 20 (door body 42) and the outer surface portion 55 (plane portion 56). The door checker 75 is a member that holds the sub door 20 in the open position.
In this door checker 75, an arm 78 is attached to a door inner frame 28a (partition frame 31) via a support bracket 76 and a support pin 77, and a case 79 is attached to the sub door 20 (door body 42).

A seal member 48 is disposed behind the door checker 75 in the vehicle body. Therefore, the seal member 48 can prevent the door checker 75 from getting wet with rainwater or the like.
Thereby, for example, it is possible to prevent rainwater or the like attached to the door checker 75 from freezing and hindering the opening and closing of the sub door 20, and to ensure good operability of the sub door 20.

As shown in FIGS. 9 and 12, the gate body 16 of the tailgate 15 is provided with a gate outer handle (outer handle) 82 for operating the locking and unlocking of the tailgate.
The gate outer handle 82 is configured such that an operator inserts his / her hand inside the gate outer handle 82 (that is, the gate main body 16 side) to operate locking / unlocking.
Therefore, the outer surface 84a of the handle part (part) 84 provided with the gate outer handle 82 in the gate body 16 is formed in a concave shape toward the front of the vehicle body so that a hand can be inserted. Thereby, the thickness dimension T1 of the handle part 84 in the gate body 16 is kept small.

  Further, the sub door 20 is provided with a door harness hole (second harness hole) 86 for guiding the harness 62 inserted through the gate harness hole 61 into the sub door 20. The door harness hole 86 is provided in front of the seal member 48 in the vehicle body. Therefore, it is possible to prevent rainwater or the like that has entered from the separation portion 51 (see FIG. 5) from entering the door harness hole 86.

The door harness hole 86 is a hole that guides the harness 62 extended from the gate harness hole 61 to the inside 39 of the sub door 20.
That is, the harness 62 extended from the gate harness hole 61 is inserted into the door harness hole 86 through the grommet. The harness 62 inserted through the door harness hole 86 is guided to the inside 39 of the sub door 20.

By the way, since the door harness hole 86 and the gate harness hole 61 need to be inserted through the harness 62, the opening size becomes large.
For this reason, it is difficult to form the door harness hole 86 and the gate harness hole 61 in the handle portion 84 where the gate outer handle 82 is provided and the thickness dimension T1 is reduced.

Here, the door harness hole 86, the gate outer handle 82, and the gate harness hole 61 are provided in this order from the top in the vertical direction. Therefore, the door harness hole 86 can be shifted upward from the gate outer handle 82, and the gate harness hole 61 can be shifted downward from the gate outer handle 82.
Accordingly, the door harness hole 86 and the gate outer handle 82 can be provided without causing the tail gate 15 to bulge rearward of the vehicle body.

Next, an example in which rainwater that has entered from the separation portion 51 of the tailgate 15 is prevented from collecting on the seal member will be described with reference to FIG.
As shown in FIG. 13A, rainwater enters the separating portion 51 as shown by an arrow B by opening the tailgate 15 when it rains. Rainwater that has entered the separation portion 51 flows to the seal member 48 (see FIG. 13B) through the separation portion 51.

As illustrated in FIG. 13B, the seal member 48 is disposed behind the gate harness hole 61 and the harness 62 so that the depression of the seal member 48 toward the vehicle compartment 22 is suppressed.
Therefore, the rainwater that has flowed to the seal member 48 side is guided along the seal member 48 toward the lower end 15a of the tailgate 15 (see FIG. 13A). Thereby, it is possible to prevent the rainwater that has entered from the separation portion 51 from collecting on the seal member 48.

In this state, the operator closes the tailgate 15 as shown by the arrow D.
Since rainwater does not collect in the seal member 48, when the tailgate 15 is closed, it is possible to prevent rainwater from scattering from the lower end 15a of the tailgate 15 (see FIG. 13A) and falling on the operator.

Further, by arranging the seal member 48 at the rear of the vehicle body of the gate harness hole 61, when the tailgate 15 is opened, rainwater that enters from the separation portion 51 (see FIG. 13A) reaches the gate harness hole 61. Intrusion can be prevented.
As a result, the sealing member 48 can prevent rainwater from entering the inside 38 of the gate body 16 from the gate harness hole 61.
