Description

Technical Field

[0001] The technology disclosed in this specification relates to a vehicle trunk door and a method for mounting a trunk door interior panel to a trunk door panel. Background Art

[0002] Patent document 1 discloses a vehicle having a vehicle body with a door opening at the rear and a trunk door that opens and closes the door opening. The trunk door has a door panel, which includes an outer panel and an inner panel having a window opening, and the outer peripheries of the two panels and the inner periphery of the window opening extend in a flange shape, and the flange-shaped portions of the outer panel and the inner panel overlap.

[0003] In addition, the interior surface of the door panel is covered by an interior trim panel. The interior trim panel has a plurality of clamps, and is configured to be installed on the door panel by bringing the interior trim panel close to the panel surface of the door panel from a substantially perpendicular direction and sequentially pushing the clamps into the holes provided in the door panel. During the installation operation, since the interior trim panel can cover the overlapping portion of the flange-shaped overlapping portion of the door panel without contacting it, the end of the interior trim panel is arranged at a position inside the overlapping portion in the window opening.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2008-260350 Summary of the invention

[0007] Problem that the invention aims to solve

[0008] In the above-mentioned conventional structure, the rear window glass that closes the window opening at the rear of the vehicle is installed on the outside of the window opening of the outer panel, and a ceramic wire is provided near the periphery of the rear window glass. The ceramic wire is used to hide the end of the interior trim panel arranged near the opening edge in the window opening so that it cannot be seen from the outside of the vehicle. Since such a ceramic wire is painted black, if it is set thick, there is a tendency for the rear field of view to be narrowed when looking from the inside of the vehicle. In addition, sometimes the appearance when looking from the outside of the vehicle is also deteriorated, so it is preferred that the ceramic wire is as thin as possible. In particular, there is a desire to reduce the radius of curvature R of the ceramic wire at the corners of the two ends of the lower side of the window opening.

[0009] However, from the above-mentioned installation direction, the end of the interior panel disposed inside the window opening is disposed inside the window opening edge relative to the overlapping portion to avoid interference with the overlapping portion of the door panel. Therefore, in order to hide the end of the interior panel, the ceramic wire needs to be thicker, and it is difficult to make the ceramic wire thinner.

[0010] The purpose of the technology disclosed in this specification is to provide a method for installing a trunk door and a trunk door interior panel relative to a trunk door panel for a vehicle, which can make the width of the ceramic wire set on the rear window glass, especially the part of the ceramic wire configured at the corner of the window opening, narrower.

[0011] Solutions for solving problems

[0012] The technology disclosed in the present specification is a trunk door for a vehicle, which can open and close a door opening provided at the rear end of the vehicle, wherein the trunk door for the vehicle comprises: a trunk door panel, which comprises a panel body portion and a window frame portion, the window frame portion being frame-shaped, extending from both end portions in the vehicle width direction of the upper end of the panel body portion and having an opening on the inner side thereof; a trunk door interior panel, which is mounted on the inner side of the vehicle interior of the panel body portion; and a rear window glass, which closes the opening in the window frame portion, the panel body portion comprising an inner panel and an outer panel arranged on the outer side of the vehicle exterior of the inner panel, the panel body portion having the inner panel at its upper end The flange portion is overlapped with the end of the outer panel to form a flange-shaped flange portion, and the flange portion is arranged on the inner side of the vehicle interior of the rear window glass. The trunk door interior panel comprises: an interior panel main body, which covers the inner surface of the vehicle interior of the panel main body; and a covering portion, which is connected to the upper end of the interior panel main body and covers the flange portion from above, and the covering portion extending along the upper end of the interior panel main body extending in the vehicle width direction has a rolling portion at least at both ends on the inner side of the opening of the window frame portion, and the rolling portion bypasses the flange portion in a manner of rolling up the flange portion and is inserted between the flange portion and the rear window glass.

[0013] According to the above structure, at least at both ends inside the opening of the window frame portion, the end (top end) of the rolled-in portion that rolls in the flange portion from above is arranged at a position lower than the end (upper end) of the flange portion, so that the width of the ceramic line provided on the rear window glass in order to hide the end of the trunk door interior panel can be reduced, and at least the width of the ceramic line at the corner between the plate body and the window frame portion can be reduced. In other words, the curvature radius R of the ceramic line at the corner between the plate body and the window frame portion can be set small, so that the field of view when viewed from the inside of the vehicle interior is extended to a position close to the corner (angle), and the appearance of the trunk door (rear window glass) when viewed from the outside of the vehicle exterior is also improved.

[0014] Alternatively, the reel-in portion may include an extension portion that extends outside the vehicle compartment of the window frame portion. According to such a structure, the curvature radius R of the portion of the ceramic wire disposed at the corner between the plate body portion and the window frame portion can be set smaller, thereby further improving the field of vision and appearance.

[0015] Alternatively, the roll-in portion may be bent so that the top end inserted between the flange portion and the rear window glass is directed toward the outer peripheral end of the rear window glass. This makes it possible to simply realize a structure in which the end (top end) of the roll-in portion for rolling in the flange portion from above is arranged at a position lower than the end (upper end) of the flange portion.

[0016] Alternatively, the roll-in portion and the flange portion may overlap in the vertical direction. Alternatively, the roll-in portion and the flange portion may be arranged in a manner that faces each other. This makes it possible to simply realize a structure in which the end (top end) of the roll-in portion that rolls in the flange portion from above is arranged at a position lower than the end (upper end) of the flange portion.

[0017] In addition, another technology disclosed in the present specification is a method for installing the trunk door interior panel of the above-mentioned vehicle trunk door to the trunk door plate, and the installation method performs the following steps: in a state in which the trunk door interior panel is erected in a manner in which the plate surface of the interior panel main body portion intersects with the plate surface of the plate main body portion, the rolled-in portion provided at one end portion of the upper end of the interior panel main body portion is inserted between the rear window glass and the flange portion from the inner surface side of the vehicle interior of the trunk door plate; The other end portion on the opposite side where the rolling-in portion is provided is moved to a position in the window frame portion that is diagonal to the rolling-in portion at the one end portion, and the rolling-in portion at the other end portion is arranged at a position that is closer to the outside of the vehicle interior than the flange portion; the rolling-in portion at the other end portion is brought close to the panel main body portion and inserted between the rear window glass and the flange portion; the interior panel main body portion is rotated in a direction toward the inner surface of the vehicle interior close to the panel main body portion with the rolling-in portion at the one end portion and the rolling-in portion at the other end portion as the rotation center.

[0018] According to the above configuration, the trunk door trim having the rolled-in portion can be attached to the trunk door panel without interfering with the flange portion.

[0019] Effects of the Invention

[0020] According to the technology disclosed in this specification, a method for installing a vehicle trunk door and a trunk door interior panel relative to a trunk door panel can be provided, which can make the width of the ceramic wire set on the rear window glass, especially the part of the ceramic wire arranged at the corner of the opening edge of the window opening, narrower.

[0035] according to Figures 1 to 9In the drawings, arrows FR and RR indicate the front and rear of the vehicle, arrows UP and DW indicate the upper and lower parts of the vehicle, and arrows R and L indicate the right and left parts of the vehicle's travel direction, respectively.

[0036] Figure 1 This is a perspective view of a trunk door (an example of a vehicle trunk door) 20 of a vehicle (an example of a vehicle) 10 of the present embodiment as viewed from the rear (back side) of the vehicle. The trunk door 20 is a hatchback-type trunk door 20 that can be opened and closed by rotating in the vertical direction around a hinge portion provided at its upper end in a door opening at the rear of the vehicle 10. In the following description, the vertical direction is a direction when the trunk door 20 is in a state of closing the door opening.

[0037] The trunk door 20 includes a trunk door panel 21 , a trunk door interior panel 30 , and a rear window glass 40 .

[0038] The trunk door panel 21 includes: a panel body portion 22, which is plate-shaped and forms the main body of the lower portion of the trunk door 20; and a window frame portion 23, which is a substantially rectangular frame-shaped and extends upward from both ends of the panel body portion 22 in the vehicle width direction (see Figure 2 The upper end of the panel body 22 is formed as the lower side of the window frame 23. A rear window glass 40 is arranged inside the window frame 23 to close the opening surrounded by the window frame 23.

[0039] In the state where the trunk door 20 closes the door opening ( Figure 1 In the state of the vehicle, the panel body 22 stands up from the floor of the vehicle in a state close to being substantially vertical. On the other hand, the left and right side portions of the window frame portion 23 extend obliquely upward from the upper end of the panel body 22 toward the front of the vehicle (see Figure 1 ).

[0040] Such a trunk door panel 21 is configured to include an inner panel 26 and an outer panel 27 disposed opposite to the inner panel 26 outside the vehicle interior. The inner panel 26 and the outer panel 27 form a flange portion 25 in which the facing surfaces overlap and engage with each other at their outer peripheral edges and the opening edge of the window frame portion 23 (the portion closed by the rear window glass 40).

[0041] Among them, Figure 3As shown, the flange portion 25 located at the upper end of the plate body portion 22 (inside the window frame portion 23) extends obliquely forward and upward in a manner roughly along the inclination direction of the window frame portion 23. In other words, the flange portion 25 extends toward the opening of the window frame portion 23. In the following description, the flange portion 25 extending from the upper end of the plate body portion 22 toward the opening of the window frame portion 23 is referred to as the inner flange portion 25A of the window frame portion. The inner flange portion 25A of the window frame portion extends in the vehicle width direction. The inner flange portion 25A of the window frame portion is a part of the trunk door panel 21, and is therefore composed of an inner panel 26 and an outer panel 27.

[0042] like Figure 3 As shown in the figure, a step portion 28 is formed on the outer side surface of the outer panel 27 near the upper end of the panel body 22 and below the inner flange portion 25A of the window frame portion. The step portion 28 is a recessed portion that is recessed one level from the main outer surface of the outer panel 27 toward the inner side of the vehicle interior. In addition, by embedding the end portion 40A of the rear window glass 40 in the step portion 28, the outer surface of the rear window glass 40 is connected to the outer surface of the main part of the outer panel 27 below the step portion 28. The rear window glass 40 is entirely overlapped with the outer surface (back side) of the window frame portion 23 facing the vehicle interior.

[0043] Furthermore, according to such a structure, the portion of the outer plate 27 of the plate body 22 that is arranged above the step portion 28 is arranged on the inner side of the vehicle interior of the rear window glass 40. That is, the window frame inner flange portion 25A and the lower portion of the rear window glass 40 are arranged to overlap in the vehicle interior and exterior direction (front and rear direction). In addition, the window frame inner flange portion 25A is arranged on the inner side (front side) of the rear window glass 40 in a state separated from the rear window glass 40.

[0044] The trunk door interior panel 30 is mounted on the inner side of the trunk door panel 21 (inner panel 26) to cover the inner side of the trunk door panel 21. The trunk door interior panel 30 includes an interior panel main body 31 (see FIG. 2 ) which is arranged below the window frame 23 and covers the panel main body 22 from the inner side of the vehicle interior. Figure 2 ).

[0045] The interior panel body 31 is arranged opposite to the panel body 22 (inner panel 26), and a plurality of clamp seats (not shown) on which clamps can be mounted are protrudingly provided on the panel surface on the outside of the vehicle interior (the panel surface opposite to the panel body 22). On the other hand, mounting holes (not shown) for inserting clamps mounted on the clamp seats are provided in the inner panel 26. Therefore, by inserting the clamps into the mounting holes, the interior panel body 31 is fixed to the inner surface of the inner panel 26.

[0046] A covering portion 33 is provided at the upper end of the interior panel main body portion 31 (see Figure 3). The covering portion 33 extends from the upper end of the interior panel main body 31 toward the rear of the vehicle. The trunk door interior panel 30 is arranged in a manner such that the upper end of the interior panel main body 31 and the upper end of the panel main body 22 are opposite to each other. The covering portion 33 extends from the upper end of the interior panel main body 31 in a direction intersecting with the extension direction of the inner flange portion 25A of the window frame portion, and covers the inner flange portion 25A of the window frame portion from above. In addition, the covering portion 33 is in the shape of a long strip extending in the vehicle width direction, and mounting portions 34 are provided at both ends in the vehicle width direction. The mounting portions 34 are used to mount the trunk door interior panel 30 on the inner peripheral surface of the opening edge of the window frame portion 23 (refer to Figure 2 and Figure 3 ).like Figure 5 As shown, the mounting portion 34 stands from the vehicle interior side surface of the covering portion 33 along the left and right side portions of the window frame portion 23 .

[0047] In the present embodiment, the covering portion 33 includes a roll-in portion 35 at both ends (one end and the other end) in the vehicle width direction, which extends so as to roll in the upper end 25B of the flange portion 25A in the window frame portion from above. Figure 3 As shown, the roll-in portion 35 is bent toward the rear at the portion overlapping with the upper end 25B of the inner flange portion 25A of the window frame portion, and extends obliquely downward along the inner flange portion 25A of the window frame portion. The top end 37 of the roll-in portion 35 inserted between the inner flange portion 25A of the window frame portion and the rear window glass 40 is bent toward the end 40A of the rear window glass 40. The top end 37 (lower end) of the roll-in portion 35 is inserted between the inner flange portion 25A of the window frame portion and the rear window glass 40. The top end 37 of the roll-in portion 35 is arranged at a position lower than the upper end 25B of the inner flange portion 25A of the window frame portion. In addition, the roll-in portion 35 and the inner flange 25A of the window frame portion overlap in the up-down direction and are arranged in a face-to-face manner.

[0048] The covering portion 33 of the present embodiment further includes an extension portion 36, which extends from the reel-in portion 35 to the outside in the vehicle width direction at both ends in the vehicle width direction, and covers the lower ends of the left and right side portions of the window frame portion 23 from the outside of the vehicle compartment (the rear and the outside in the vehicle width direction) (see FIG. Figure 4 , Figure 5 The extension portion 36 extends from the reel-in portion 35 to the rear side of the lower end portions of the left and right side portions of the window frame portion 23 and to the outside of the vehicle in the vehicle width direction. In other words, the extension portion 36 is disposed at a portion that is further rearward than the opening edge portion 23A of the window frame portion 23 and to the outside of the vehicle in the vehicle width direction.

[0049] like Figure 1As shown, a ceramic wire 41 is arranged at the peripheral portion of the rear window glass 40. In the present embodiment, the ceramic wire 41 provided at the lower end of the rear window glass 40 can cover the top end portion 37 (the end of the trunk door interior panel 30) of the rolled-in portion 35 and the extended portion 36 from the outside of the vehicle exterior. The ceramic wire 41 is arranged on the vehicle interior surface of the rear window glass 40 in a dark color such as black. The ceramic wire 41 is arranged in a manner to cover the top end portion 37 from the outside of the vehicle exterior, thereby assuming the function of making the top end portion 37 invisible from the outside of the vehicle.

[0050] In this embodiment, the covering portion 33 of the trunk door interior panel 30 has a rolled-in portion 35 and an extended portion 36, thereby being different from the conventional structure that does not have the rolled-in portion 35 and the extended portion 36 (see Figure 10 to Figure 12 ), the top end portion 37 is arranged at a position closer to the end of the rear window glass 40. That is, the ceramic wire 41 for hiding the top end portion 37 of the trunk door interior panel 30 can be retracted to a position closer to the end of the rear window glass 40, thereby reducing the width of the ceramic wire 41. In particular, the inner end of the ceramic wire 41 arranged at the corner 24 formed by the left and right side portions of the interior panel main body 31 and the window frame portion 23 can be made close to the outer edge of the corner of the rear window glass 40 (the curvature radius R of the ceramic wire 41 can be reduced). That is, the width of the ceramic wire 41 at the corner 24 can be reduced. Therefore, the field of vision when viewed from the inside of the vehicle interior is expanded, and the appearance when viewed from the outside of the vehicle interior is also improved (refer to Figure 1 , Figure 5 , Fig.10 as well as Fig.12 ). In addition, in the trunk door 110 of the comparative example, Figure 10 to Figure 12 In the present embodiment, the same structures as those in the above-mentioned embodiment are denoted by the same reference numerals, and the different structures are denoted by the reference numerals of the present embodiment plus 100, and repeated descriptions are omitted.

[0051] like Fig.11 As shown in FIG. 1 , the covering portion 133 is not bent from the upper end of the interior panel body 131 toward the rear of the vehicle but extends straightly. According to such a structure, since the top end of the covering portion 133 is located away from the outer peripheral end of the rear window glass 140, the width of the ceramic wire 141 increases. In particular, at the corner 124 between the interior panel body 131 and the window frame 23, the width of the ceramic wire 141 increases, and the curvature radius R of the ceramic wire 141 increases (refer to FIG. 1 ). Fig.10 , Fig.12 ). Therefore, the visual field when viewed from the inner side of the vehicle interior becomes narrow, and the appearance when viewed from the outer side of the vehicle exterior is also not good.

[0052] The structure of the vehicle trunk door 20 of the present embodiment is as described above. Next, the installation method of the trunk door interior panel 30 to the trunk door panel 21 will be described. In addition, as described above, the trunk door interior panel 30 of the present embodiment is provided with a roll-in portion 35 in the form of rolling up the inner flange portion 25A of the window frame portion from above, and a protruding portion 36 connected to the roll-in portion 35 and arranged on the outer side of the vehicle exterior of the window frame portion 23 (the rear and the outer side of the vehicle exterior in the vehicle width direction). Therefore, if the interior panel body 31 is installed on the board surface of the board body 22 from a direction perpendicular to the board surface of the board body 22 as in the past, the roll-in portion 35 will interfere with the inner flange portion 25A of the window frame portion, and the protruding portion 36 will interfere with the window frame portion 23, and the installation cannot be performed. Therefore, the installation is performed by the method shown below.

[0053] When installing the trunk door interior panel 30 on the trunk door panel 21, first, in a manner that the panel surface of the interior panel main body 31 and the panel surface of the panel main body 22 intersect, the rear end of the trunk door interior panel 30 is slightly lifted to tilt the trunk door interior panel 30, and one of the two roll-in portions 35 provided at both ends of the upper end of the interior panel main body 31 is inserted from the inner surface side of the trunk door panel 21 between the rear window glass 40 and the inner flange portion 25A of the window frame portion.

[0054] By arranging the interior panel main body 31 in an inclined direction in which its panel surface intersects with the panel surface of the panel main body 22, it is possible to avoid the situation in which the rolled-in portion 35 in a so-called under shape interferes with the inner flange portion 25A of the window frame portion during installation and cannot be arranged between the rear window glass 40 and the inner flange portion 25A of the window frame portion. The so-called under shape is a shape in which the rolled-in portion 35 is bent toward the rear at the portion overlapping with the upper end 25B of the inner flange portion 25A of the window frame portion and extends obliquely downward along the inner flange portion 25A of the window frame portion.

[0055] In addition, at this time, the other of the two rolled-in portions 35 is pre-arranged on the inner side of the panel body portion 22. In this way, the extension portion 36 connected to the one rolled-in portion 35 inserted between the rear window glass 40 and the inner flange portion 25A of the window frame portion can be slid from the inner side of the opening of the window frame portion 23 to the outer side of the window frame portion 23 (from the inner side of the opening to the outer side in the vehicle width direction).

[0056] In this way, when the sliding of the extension portion 36 is completed, the rolled-in portion 35 is arranged between the window frame inner flange portion 25A and the rear window glass 40, and the extension portion 36 is arranged between the window frame portion 23 and the rear window glass 40 (see FIG. Figure 3 and Figure 4 ).

[0057] Then, if Figure 6 As shown in FIG. 1 , the tailgate door trim panel 30 is tilted so that the other end 31R of the trim panel main body 31 having the other roll-in portion 35 is located above the one end 31L having the one roll-in portion 35 disposed between the window frame inner flange portion 25A and the rear window glass 40. That is, the other end 31R of the trim panel main body 31 is moved to a position diagonally opposite to the one end 31L in the substantially rectangular window frame 23 (a position in the window frame 23 opposite to the panel main body 22) (see FIG. 1 ). Figure 6 ). After that, the other rolled-in portion 35 and the extended portion 36 are arranged at a position on the outside (rear) of the vehicle interior in the vehicle interior and exterior direction (front-rear direction) of the upper end 25B (top end) of the flange portion 25A in the window frame portion and the window frame portion 23 through the opening of the window frame portion 23. By moving the other end 31R of the interior panel main body 31 to a position away from the panel main body 22 and to a position diagonal to the one end 31L in the window frame portion 23, the other rolled-in portion 35 and the extended portion 36 in the upper end of the trunk door interior panel 30 having a width dimension longer than the opening width of the window frame portion 23 can be arranged from the vehicle interior side surface of the panel main body 22 to a position on the outside (rear) of the vehicle exterior than the upper end 25B of the flange portion 25A in the window frame portion and the window frame portion 23 through the opening of the window frame portion 23.

[0058] Next, the other end portion 31R is lowered so that the other rolled-in portion 35 and the extended portion 36 on the other end portion 31R side, which are arranged on the outside (rearward) of the vehicle interior than the upper end 25B of the window frame inner flange portion 25A and the window frame portion 23, are brought closer to the panel body portion 22. Then, the other rolled-in portion 35 on the other end portion 31R side is inserted between the window frame inner flange portion 25A and the rear window glass 40, and the extended portion 36 is inserted between the window frame portion 23 and the rear window glass 40 (see FIG. 2 ). Figure 7 ). Thus, two left and right rolled-in portions 35 are arranged on the vehicle exterior side (rear side) of the window frame inner flange portion 25A arranged in the opening of the window frame portion 23 in the panel body portion 22, and two extended portions 36 are arranged on the vehicle exterior side of the window frame portion 23. In this state, the interior panel body portion 31 is still arranged to be inclined in the front-rear direction in a manner that its panel surface intersects with the panel surface of the panel body portion 22.

[0059] Finally, the lower end of the interior panel body 31 is rotated toward the lower end of the panel body 22 with the upper end (the two ends 31R and 31L forming the rolled-in portion 35) as the rotation center. Thus, the clamp protruding toward the outer surface of the interior panel body 31 is inserted into the mounting hole of the panel body 22, and the interior panel body 31 is mounted on the panel body 22 (see FIG. Figure 2 and Fig. 9 ).

[0060] In addition, the operation of installing the trunk door interior panel to the trunk door plate is currently performed as described below. The trunk door plate integrally connected by means of a hinge portion provided at an opening edge portion above the door opening of the vehicle body is flipped up to open the door opening, and the trunk door interior panel is installed relative to the trunk door plate in the flipped-up state. In the past, the structure was such that the interior panel main body portion was arranged so that the surfaces were opposite to each other and parallel with respect to the plate main body portion, and the interior panel main body portion was vertically close to the plate main body portion. Therefore, when installing the interior panel main body portion relative to the trunk door plate (plate main body portion) in a state where the installation surface is facing downward with respect to the flipped-up state, in order to prevent the trunk door interior panel from falling, the trunk door interior panel must be supported above the head while the clamp is pushed in, and such installation operation is not easy.

[0061] In contrast, according to the trunk door 20 of the present embodiment, first, the trunk door trim panel 30 is brought close to the plate surface of the plate main body 22 in an inclined manner so that the plate surface of the trim panel main body 31 intersects with the plate surface of the plate main body 22 of the trunk door panel 21 in a state where the door opening is open. Then, by inserting a roll-in portion 35 provided at one end portion 31L between the window frame inner flange portion 25A and the rear window glass 40, the roll-in portion 35 can be hooked with respect to the window frame inner flange portion 25A. In other words, the following state is achieved: in the state where the roll-in portion 35 is inserted between the window frame inner flange portion 25A and the rear window glass 40, even if the hand is released from the trunk door trim panel 30, the trim panel main body 31 is not easy to fall from the plate main body 22. Therefore, compared with the conventional structure, the installation operation of the trunk door trim panel 30 with respect to the trunk door panel 21 can be easily performed.

[0062] The trunk door 20 of the present embodiment enables the door opening provided at the rear end of the vehicle 10 to be opened and closed, and comprises: a trunk door panel 21, which comprises a panel body portion 22 and a window frame portion 23, the window frame portion 23 being frame-shaped, extending from both ends in the vehicle width direction of the upper end of the panel body portion 22 and having an opening on the inner side thereof; a trunk door interior panel 30, which is mounted on the inner side of the panel body portion 22 for the vehicle interior; and a rear window glass 40, which closes the opening in the window frame portion 23, the panel body portion 22 comprising an inner panel 26 and an outer panel 27 arranged on the outer side of the inner panel 26 for the vehicle interior, the panel body portion 22 having a flange-shaped window frame portion inner end formed by overlapping the ends of the inner panel 26 and the outer panel 27 at its upper end. The flange portion 25A, the inner flange portion 25A of the window frame portion is arranged on the inner side of the rear window glass 40 in the vehicle cabin, and the trunk door interior panel 30 has: an interior panel main body portion 31, which covers the inner surface of the panel main body portion 22 in the vehicle cabin; and a covering portion 33, which is connected to the upper end of the interior panel main body portion 31 and covers the inner flange portion 25A of the window frame portion from above. The covering portion 33 extending along the upper end of the interior panel main body portion 31 extending in the vehicle width direction has a rolling portion 35 at both ends on the inner side of the opening of the window frame portion 23. The rolling portion 35 bypasses the inner flange portion 25A of the window frame portion in a manner of rolling up the inner flange portion 25A of the window frame portion and is inserted between the inner flange portion 25A of the window frame portion and the rear window glass 40.

[0064] In addition, the reeled portion 35 includes an extended portion 36 that is wound around the vehicle interior outer side of the window frame portion 23. According to such a structure, the curvature radius R of the portion of the ceramic wire 41 disposed at the corner portion 24 between the panel body portion 22 and the side portion of the window frame portion 23 can be set smaller, thereby further improving the field of vision and appearance.

[0065] In addition, the mounting method of the trunk door interior panel 30 of the present embodiment for mounting the trunk door panel 21 of the trunk door 20 is a mounting method that performs the following steps: in a state where the trunk door interior panel 30 is erected in a configuration in which the plate surface of the interior panel main body 31 intersects with the plate surface of the plate main body 22, a reel-in portion 35 provided at one end portion 31L is inserted between the rear window glass 40 and the flange portion 25A inside the window frame portion from the inner surface side of the vehicle interior of the trunk door panel 21; and a portion of the interior panel main body 31 opposite to the one end portion 31L in the vehicle width direction is arranged so that The other end 31R of the window frame portion 23, which is provided with another rolling portion 35, is moved to a position diagonally opposite to a rolling portion at one end 31L, and the other rolling portion 35 is arranged at a position closer to the outside of the vehicle interior than the inner flange portion 25A of the window frame portion; the other rolling portion 35 is brought close to the panel main body 22 and inserted between the rear window glass 40 and the inner flange portion 25A of the window frame portion; the interior panel main body 31 is rotated in the direction of the vehicle interior surface close to the panel main body 22 with one rolling portion 35 and the other rolling portion 35 as the rotation center.

[0066] According to the above configuration, the trunk door trim 30 having the rolled-in portion 35 can be attached to the trunk door panel 21 without interfering with the window frame inner flange portion 25A.
