Detailed Implementation

[0023] The following describes one implementation of the car door.

[0024] <Structure of this embodiment>

[0025] like Figure 1As shown, the door 10 includes a door body 20, a door frame 30, a window frame trim 40, a window frame decorative piece 50, a glass guide channel 60, an end cover 80, a movable panel 90, and a window regulator 100.

[0026] In this embodiment, door 10 is the front door on the right side of the vehicle. Furthermore, door 10 is a swing door that rotates between a fully closed position (fully closed) and a fully open position (fully open). Hereinafter, the thickness direction of door 10 is defined as "thickness direction X," and the extension direction of the rotation axis of door 10 is defined as "vertical direction Z." Further, the portion of door 10 that is rotatably supported on the vehicle body via a door hinge is defined as the front end of door 10. On the other hand, the portion of door 10 that is constrained to the vehicle body via a door lock mechanism is defined as the rear end of door 10.

[0027] In this embodiment, the vertical direction Z of the door 10 aligns with the vertical direction of the vehicle. Furthermore, the longitudinal direction Y of the door 10 in the fully closed position aligns with the longitudinal direction of the vehicle. Additionally, the thickness direction X of the door 10 in the fully closed position aligns with the width direction of the vehicle. Hereinafter, the structure of the door 10 will be described according to the direction of the door 10. That is, the constituent parts of the door 10 will be described using the direction of the door 10.

[0028] <Main Gate 20>

[0029] like Figure 1 As shown, the door body 20 has an inner panel 21 and an outer panel 22. The door body 20 is preferably made of a lightweight and highly rigid metal material. Both the inner panel 21 and the outer panel 22 are plate-shaped. The inner panel 21 and the outer panel 22 are joined together by welding or the like. There is space between the inner panel 21 and the outer panel 22 for accommodating the constituent parts of the door 10.

[0030] <Door frame 30>

[0031] like Figure 2 As shown, the door frame 30 has a rear window frame 31, a front window frame 32, and an upper window frame 33. The door frame 30 is preferably made of a lightweight and rigid metal material. The door frame 30 can be constructed, for example, by joining two panels together, similar to the door body 20.

[0032] The rear window frame 31 has a pillar portion 31a and a window frame portion 31b. The pillar portion 31a is a flat cylindrical component. The long side of the pillar portion 31a is in the vertical direction (Z). The pillar portion 31a overlaps with the center pillar of the vehicle when the door 10 is in the fully closed position. The window frame portion 31b is a cylindrical component. The long side of the window frame portion 31b is in the vertical direction (Z). The length of the window frame portion 31b is longer than the length of the pillar portion 31a. Specifically, the upper end of the window frame portion 31b is the same as the upper end of the pillar portion 31a, but the lower end of the window frame portion 31b is located below the lower end of the pillar portion 31a. The window frame portion 31b is a guide rail component for guiding the lifting and lowering of the movable panel 90. The pillar portion 31a and the window frame portion 31b are integrally formed. The pillar portion 31a is the rear part of the rear window frame 31, and the window frame portion 31b is the front part of the rear window frame 31.

[0033] The front window frame 32 is a cylindrical component. The long side of the front window frame 32 is in the vertical direction (Z). The long side of the front window frame 32 is in approximately the same direction as the window frame portion 31b of the rear window frame 31. The front window frame 32 is located at a distance from the rear window frame 31 in the longitudinal direction (Y). The front window frame 32 extends parallel to the rear window frame 31. The front window frame 32 is a guide rail component for guiding the lifting and lowering of the movable panel 90. The upper window frame 33 is a cylindrical component. The upper window frame 33 connects the upper end of the window frame portion 31b of the rear window frame 31 and the upper end of the front window frame 32 in the longitudinal direction (Y). The upper window frame 33 has a first portion 33a extending in the longitudinal direction (Y) and a second portion 33b that faces downwards as it moves forward from the front end of the first portion 33a. The rear end of the first portion 33a is connected to the rear window frame 31. The front end of the second portion 33b is connected to the upper end of the front window frame 32.

[0034] like Figure 1 As shown, the door frame 30 is connected to the door body 20. In this way, the door frame 30 constitutes the window frame of the car door 10.

[0035] <Window frame trim 40>

[0036] like Figure 2 As shown, the window frame trim 40 has a first trim 40a and a second trim 40b.

[0037] The first trim strip 40a is rod-shaped. The length of the first trim strip 40a is longer than the length of the first part 33a of the upper window frame 33 of the door frame 30. The first trim strip 40a is formed, for example, by rolling a sheet metal.

[0038] like Figures 3-5 As shown, the first trim strip 40a has a fixing plate 41, a decorative plate 42, a lower clamping plate 43, and an upper clamping plate 44.

[0039] The fixing plate 41 intersects the vertical direction Z. The decorative plate 42 intersects the thickness direction X. The lower clamping plate 43 is connected to the lower end of the decorative plate 42. There is a gap between the lower clamping plate 43 and the decorative plate 42 in the thickness direction X. The upper clamping plate 44 is connected to the upper end of the decorative plate 42. There is a gap between the upper clamping plate 44 and the decorative plate 42 in the thickness direction X. In the first trim strip 40a, the decorative plate 42 and the lower clamping plate 43 are aligned with the rear end of the upper clamping plate 44. On the other hand, the front end of the fixing plate 41 is located behind the front ends of the decorative plate 42, the lower clamping plate 43, and the upper clamping plate 44.

[0040] like Figure 1 As shown, the first trim strip 40a is fixed to the door frame 30 along the upper end of the door frame 30. Specifically, the first trim strip 40a is fixed to the first portion 33a of the upper window frame 33 via a fixing plate 41. For example, the first trim strip 40a can be fixed using fasteners such as rivets. With the first trim strip 40a fixed to the upper window frame 33, the rear end of the first trim strip 40a is located rearward compared to the rear end of the first portion 33a of the upper window frame 33. That is, when the door 10 is viewed from the width direction, the first trim strip 40a protrudes rearward from the upper window frame 33. Alternatively, the first trim strip 40a can also be fixed to the pillar portion 31a of the door frame 30. In this case, the first trim strip 40a can be riveted to the pillar portion 31a of the door frame 30.

[0041] like Figure 1 and Figure 2 As shown, the second trim strip 40b is panel-shaped. The second trim strip 40b is formed, for example, by injection molding of resin material. The second trim strip 40b is fixed to the second portion 33b of the upper window frame 33. As an example, the second trim strip 40b can be fixed using fastening components such as double-sided tape and clips.

[0042] <Window Frame Decorations 50>

[0043] like Figure 2 and Figure 3 As shown, the window frame trim 50 has a main body 51 and a locking wall 52. The window frame trim 50 can be made of, for example, resin.

[0044] The main body 51 is a plate-shaped component of the same size as the pillar portion 31a of the rear window frame 31. A locking wall 52 extends from the upper end of the main body 51. The extending direction of the locking wall 52 is consistent with the thickness direction of the main body 51. A window frame trim 50 is installed on the pillar portion 31a of the rear window frame 31. At this time, the window frame trim 50 is located below the rear end of the window frame trim 40. The window frame trim 50 can be glued to the rear window frame 31, or it can be fixed to the rear window frame 31 using fasteners such as double-sided tape and clips.

[0045] <Glass guide channel 60>

[0046] like Figure 2 As shown, the glass guide channel 60 has a rear portion 61, a front portion 62, an upper portion 63, a connecting portion 64, and an extension portion 70. The glass guide channel 60 can be made of an elastomer such as rubber or resin with moderate elasticity. In this case, the glass guide channel 60 can be manufactured by injection molding.

[0047] like Figure 6 As shown, the rear portion 61 has multiple lips. The rear portion 61 is mounted to the window frame portion 31b of the rear window frame 31. Although not shown in the figure, the front portion 62 also has multiple lips, just like the rear portion 61. The front portion 62 and the rear portion 61 are also mounted to the front window frame 32. Figure 7 As shown, the upper portion 63 has multiple lips. The upper portion 63 is mounted on the upper window frame 33 and the window frame trim 40.

[0048] like Figure 2 and Figure 3 As shown, the connecting portion 64 extends rearward from the rear end of the upper portion 63. The connecting portion 64 connects the upper portion 63 and the extension portion 70 along the front-rear direction Y. In this embodiment, the cross-sectional shape of the connecting portion 64 orthogonal to the long side direction is different from the cross-sectional shape of the upper portion 63 orthogonal to the long side direction, and also different from the cross-sectional shape of the extension portion 70 orthogonal to the long side direction described later. In other embodiments, the cross-sectional shape of the connecting portion 64 orthogonal to the long side direction may be the same as the cross-sectional shape of the upper portion 63 orthogonal to the long side direction, or it may be the same as the cross-sectional shape of the extension portion 70 orthogonal to the long side direction.

[0049] like Figure 2 and Figure 3 As shown, the extension portion 70 extends rearward from the rear end of the connecting portion 64. In other words, the extension portion 70 extends rearward from the rear end of the upper portion 63 via the connecting portion 64. The cross-sectional shape of the extension portion 70, orthogonal to the long side direction, is the same in that long side direction. Figures 3-5 As shown, the extension part 70 has a main wall 71, an inner wall 72, an outer wall 73, a base lip 74, an inner lip 75, an outer lip 76, a covering lip 77, an inner engaging lip 78a, an outer engaging lip 78b, an inner rib 79a, and an outer rib 79b.

[0050] The main wall 71, inner wall 72, and outer wall 73 are plate-shaped. When the extended portion 70 is viewed from the long side direction, the inner wall 72 extends from the inner end of the main wall 71, and the outer wall 73 extends from the outer end of the main wall 71. The inner wall 72 and outer wall 73 extend from the main wall 71 in approximately the same direction. As a result, the cross-sectional shape of the extended portion 70, orthogonal to the long side direction, is approximately C-shaped. The thickness of the base end of the outer wall 73 is thinner than the thickness of the base end of the inner wall 72. As a result, the outer wall 73 is more prone to bending and deformation relative to the main wall 71 compared to the inner wall 72. The base lip 74, inner lip 75, outer lip 76, and cover lip 77 are plate-shaped. The base lip 74 protrudes from the outer surface of the main wall 71. The inner lip 75 protrudes from the outer surface of the inner wall 72. The outer lip 76 protrudes from the outer surface of the outer wall 73. Here, the outer surfaces of the main wall 71, the inner wall 72, and the outer wall 73 are opposite to the surfaces facing the space surrounded by the main wall 71, the inner wall 72, and the outer wall 73. The covering lip 77 protrudes from the top of the outer wall 73 toward the top of the inner wall 72. The covering lip 77 is a larger lip than the base lip 74, the inner lip 75, and the outer lip 76.

[0051] The inner engaging lip 78a protrudes from the top of the inner wall 72. The protruding direction of the inner engaging lip 78a is opposite to the direction from the inner wall 72 toward the outer wall 73. The outer engaging lip 78b protrudes from the top of the outer wall 73. The protruding direction of the outer engaging lip 78b is opposite to the direction from the outer wall 73 toward the inner wall 72. Compared with the base lip 74, inner lip 75, outer lip 76, and covering lip 77, the inner engaging lip 78a and outer engaging lip 78b are thicker and shorter in the protruding direction. Because of this, the inner engaging lip 78a and outer engaging lip 78b are less prone to deformation compared with the base lip 74, inner lip 75, outer lip 76, and covering lip 77.

[0052] An inner rib 79a protrudes from the outer surface of the inner wall 72. The inner rib 79a is positioned on the inner wall 72 between the positions where the inner lip 75 and the inner engaging lip 78a are formed. The inner rib 79a has a very low height. An outer rib 79b protrudes from the outer surface of the outer wall 73. The outer rib 79b is positioned on the outer wall 73 between the positions where the outer lip 76 and the outer engaging lip 78b are formed. The outer rib 79b has a very low height.

[0053] <End cap 80>

[0054] like Figures 3-5As shown, the end cap 80 includes an upper wall 81, an inner engaging wall 82, an outer engaging wall 83, a clamping wall 84, a guide wall 85, an inner protrusion 86, an outer protrusion 87, and a cap body 88. The end cap 80 may be made of, for example, resin.

[0055] The upper wall 81, inner locking wall 82, outer locking wall 83, clamping wall 84, and guide wall 85 are all rectangular plates. The thickness directions of the upper wall 81 and guide wall 85 are approximately the same. The thickness directions of the inner locking wall 82, outer locking wall 83, and clamping wall 84 are also approximately the same. When the upper wall 81 is viewed from the length direction, the inner locking wall 82 extends downward from the middle of the upper wall 81. On the other hand, when the upper wall 81 is viewed from the long side direction, the outer locking wall 83 extends upward and downward from the outer end of the upper wall 81. In addition, when the upper wall 81 is viewed from the long side direction, the clamping wall 84 extends downward from the inner end of the upper wall 81. Because of this, in the thickness direction X, the inner locking wall 82 is opposite to the outer locking wall 83 and opposite to the clamping wall 84. The lower end of the inner engaging wall 82 is located below the lower ends of the outer engaging wall 83 and the clamping wall 84. The front end of the inner engaging wall 82 coincides with both the front ends of the outer engaging wall 83 and the clamping wall 84. On the other hand, the rear end of the inner engaging wall 82 is approximately the same as the rear end of the clamping wall 84. The rear end of the outer engaging wall 83 is located rearward compared to the rear end of the inner engaging wall 82. The guide wall 85 extends from the lower end of the inner engaging wall 82 along the thickness direction of the inner engaging wall 82. Alternatively, the rear end of the outer engaging wall 83 may be located forward compared to the rear end of the inner engaging wall 82.

[0056] Both the inner protrusion 86 and the outer protrusion 87 are rib-shaped. The inner protrusion 86 protrudes from the inner engaging wall 82 toward the outer engaging wall 83. The inner protrusion 86 is provided along the long side of the inner engaging wall 82. The outer protrusion 87 protrudes from the outer engaging wall 83 toward the inner engaging wall 82. The outer protrusion 87 is provided along the long side of the outer engaging wall 83. In the thickness direction of the upper wall 81, the distance from the upper wall 81 to the inner protrusion 86 is longer than the distance from the upper wall 81 to the outer protrusion 87. Thus, the upper end of the inner protrusion 86 is located below the upper end of the outer protrusion 87.

[0057] The cover body 88 is plate-shaped. The thickness direction of the cover body 88 is orthogonal to the thickness direction of the outer engaging wall 83. The shape of the cover body 88 when viewed from the thickness direction is larger than the shape of the first trim 40a when viewed from the long side. The cover body 88 is located at the rear end of the outer engaging wall 83.

[0058] like Figure 3As shown, the end cap 80 is mounted on the rear end of the first trim strip 40a. Specifically, the outer engaging wall 83 of the end cap 80 is inserted into the first trim strip 40a from the rear. At this time, the outer engaging wall 83 of the end cap 80 is clamped by the decorative panel 42 of the first trim strip 40a, the lower clamping plate 43, and the upper clamping plate 44. Furthermore, the cover body 88 of the end cap 80 contacts and covers the rear end of the first trim strip 40a. Additionally, although not shown in the figure, the door 10 preferably has a front cover that covers the front end of the first trim strip 40a.

[0059] like Figure 1 and Figure 8 As shown, the end cap 80 is located near the upper end of the pillar portion 31a of the rear window frame 31. At this time, the inner engaging wall 82 and the clamping wall 84 of the end cap 80 clamp the upper end of the pillar portion 31a of the door frame 30 in the thickness direction X. In addition, the locking wall 52 of the window frame trim 50 is locked to the guide wall 85 of the end cap 80.

[0060] <Modible Panel 90>

[0061] like Figure 2 As shown, the movable panel 90 has a panel body 91 and a slider 92. The panel body 91 is a window glass. The panel body 91 is preferably made of transparent glass or resin. The slider 92 is a long strip in the shape of a plate. The length of the slider 92 is equal to the length of the rear end of the panel body 91. The slider 92 engages with the inner surface of the panel body 91 along the rear end of the panel body 91. At this time, the slider 92 protrudes rearward relative to the rear end of the panel body 91.

[0062] like Figure 1 As shown, the lower end of the movable panel 90 is supported by the window regulator 100. Thus, the movable panel 90 can be raised and lowered between a fully closed position (with the window opening fully closed) and a fully open position (with the window opening fully open). Furthermore, regardless of the position of the movable panel 90, its rear and front ends are received within the glass guide channel 60. Figure 6 As shown, the slider 92 of the movable panel 90 is housed in the rear portion 61 of the glass guide channel 60. As a result, the rear end of the movable panel 90 is blocked from the rear window frame 31 by the rear portion 61 of the glass guide channel 60. Although not shown in the figure, the front end of the movable panel 90 is housed in the front portion 62 of the glass guide channel 60. As a result, the front end of the movable panel 90 is blocked from the front window frame 32 by the front portion 62 of the glass guide channel 60. On the other hand, the upper end of the movable panel 90 is housed in the glass guide channel 60 when the movable panel 90 is in the fully closed position. Figure 7 As shown, the upper end of the movable panel 90, positioned in the fully closed position, is housed in the upper portion 63 of the glass guide channel 60. As a result, the upper end of the movable panel 90 and the upper window frame 33 are blocked by the upper portion 63 of the glass guide channel 60.

[0063] Furthermore, in the movable panel 90, the portion that contacts the front portion 62 and the upper portion 63 of the glass guide channel 60 is the panel body 91, while the portion that contacts the rear portion 61 of the glass guide channel 60 is the panel body 91 and the slider 92. Therefore, when the movable panel 90 is raised or lowered, the panel body 91 slides along the front portion 62 and the upper portion 63 of the glass guide channel 60, while the panel body 91 and the slider 92 slide along the rear portion 61 of the glass guide channel 60.

[0064] like Figure 6 As shown, the surface of the panel body 91 of the movable panel 90 and the surface of the window frame trim 50 form approximately the same plane. Thus, the movable panel 90 is flush with the window frame trim 50. Furthermore, the gap between the movable panel 90 and the window frame trim 50 is closed by the rear portion 61 of the glass guide channel 60.

[0065] <The function of this implementation method>

[0066] The function of installing the glass guide channel 60 onto the door frame 30 is explained.

[0067] The installation process of the glass guide channel 60 follows the process of installing the first trim strip 40a, which is integrated with the end cover 80, onto the door frame 30. Furthermore, the installation process of the glass guide channel 60 precedes the process of installing the window frame trim 50 and the movable panel 90 onto the door frame 30.

[0068] like Figure 6 As shown, the rear portion 61 of the glass guide channel 60 is pushed into the space defined by the rear window frame 31 of the door frame 30. Although not shown in the figure, the front portion 62 of the glass guide channel 60 is pushed into the space defined by the front window frame 32 of the door frame 30. Figure 7 As shown, the upper portion 63 of the glass guide channel 60 is pushed into the space defined by the upper window frame 33 and the window frame trim 40 of the door frame 30. When the rear portion 61, front portion 62, and upper portion 63 of the glass guide channel 60 are pushed into this space, they temporarily undergo elastic deformation. When the installation of the rear portion 61, front portion 62, and upper portion 63 of the glass guide channel 60 relative to the space is completed, they return to their original positions. Thus, the rear portion 61, front portion 62, and upper portion 63 of the glass guide channel 60 remain within the door frame 30.

[0069] like Figure 9As shown, the extension portion 70 of the glass guide channel 60 is inserted into the space between the inner engaging wall 82 and the outer engaging wall 83 of the end cap 80 (hereinafter referred to as the "receiving space SP"). At this time, the receiving space SP opens downwards in the vertical direction Z and outwards in the thickness direction X. Therefore, as... Figure 9 As indicated by the straight arrow, the extension portion 70 is pushed into the receiving space SP of the end cap 80, facing upwards and inwards in the thickness direction X. At this time, the extension portion 70 of the glass guide channel 60, like other parts of the glass guide channel 60, is pushed into the receiving space SP of the end cap 80 while elastically deforming. Specifically, the extension portion 70 makes sliding contact with the inner engaging wall 82, the outer engaging wall 83, the inner protrusion 86, and the outer protrusion 87 of the end cap 80. When the extension portion 70 is pushed deep into the receiving space SP of the end cap 80, as... Figure 8 As shown, the extension mounting section 70 is installed relative to the end cap 80. In other words, the extension mounting section 70 remains attached to the end cap 80. When the extension mounting section 70 is installed, the window frame trim 50 is installed onto the pillar portion 31a of the rear window frame 31. Additionally, the movable panel 90 is installed to be received in the glass guide channel 60.

[0070] like Figure 8 As shown, with the extension portion 70 installed on the end cap 80, the base lip 74 of the extension portion 70 contacts the upper wall 81 of the end cap 80 in a state of elastic deformation. The inner lip 75 of the extension portion 70 contacts the upper end of the inner engaging wall 82 and the inner protrusion 86 of the end cap 80 in a state of elastic deformation. The outer lip 76 of the extension portion 70 contacts the upper end of the outer engaging wall 83 and the outer protrusion 87 of the end cap 80 in a state of elastic deformation. Because of this, the upper ends of the inner protrusion 86 and the outer protrusion 87 of the end cap 80 are respectively engaged by the inner lip 75 and the outer lip 76 of the extension portion 70.

[0071] Furthermore, the inner rib 79a of the extension portion 70 contacts the inner protrusion 86 of the end cap 80. Similarly, the outer rib 79b of the extension portion 70 contacts the first trim 40a. This restricts the displacement of the extension portion 70 relative to the end cap 80. Further, the inner engaging lip 78a of the extension portion 70 contacts the inner protrusion 86 of the end cap 80 from below, and the outer engaging lip 78b of the extension portion 70 contacts the lower end of the window frame trim 40 from below. Therefore, even if the operator or working device further pushes the extension portion 70, the extension portion 70 cannot move further in that direction.

[0072] like Figure 8As shown, the covering lip 77 of the extended portion 70 contacts the upper end of the window frame trim 50. On the other hand, the outer engaging lip 78b of the extended portion 70 contacts the lower end of the window frame trim 40. Thus, the covering lip 77 and the outer engaging lip 78b of the extended portion 70 completely seal the gap between the window frame trim 40 and the window frame trim 50. In other words, there is no gap between the window frame trim 40 and the window frame trim 50. Because of this, in this embodiment, the covering lip 77 and the outer engaging lip 78b of the extended portion 70 are equivalent to a "closing portion".

[0073] <Effects of this implementation method>

[0074] (1) In the door 10, the covering lip 77 and the outer engaging lip 78b of the extension portion 70 of the glass guide channel 60 close the gap between the window frame trim 40 and the window frame trim 50. Therefore, even if the surfaces of the movable panel 90 and the window frame trim 50 are made flat, gaps between the window frame trim 40 and the window frame trim 50 can be suppressed. As a result, the door 10 can suppress the deterioration of its appearance or the generation of wind noise when the vehicle is in motion. In addition, the extension portion 70 of the glass guide channel 60 is held by the end cap 80 covering the window frame trim 40. Therefore, the door 10 does not require additional structure for holding the extension portion 70 of the glass guide channel 60.

[0075] (2) In the extension portion 70 of the glass guide channel 60, the inner lip 75 contacts the inner engaging wall 82 of the end cover 80 from above, and also contacts the inner protrusion 86 of the end cover 80 from above. Similarly, the outer lip 76 contacts the outer engaging wall 83 of the end cover 80 from above, and also contacts the outer protrusion 87 of the end cover 80 from above. Therefore, the door 10 can prevent the extension portion 70 of the glass guide channel 60 from falling downward from the end cover 80.

[0076] (3) When the extension portion 70 of the glass guide channel 60 is installed on the end cap 80, the extension portion 70 is pushed into the receiving space SP of the end cap 80. In this case, as Figure 9 As shown by the straight arrow, the extension portion 70 is pushed into the end cover 80 in an upward direction as it moves inward toward the door 10. That is, when the extension portion 70 is pushed into the end cover 80, the inner lip 75 is difficult to engage with the inner protrusion 86. Because of this, in the end cover 80 of this embodiment, the upper end of the inner protrusion 86 is located lower than the upper end of the outer protrusion 87. Therefore, when the extension portion 70 is pushed into the end cover 80, the inner lip 75 of the extension portion 70 easily engages with the inner protrusion 86 of the end cover 80. As a result, the door 10 can improve the workability of installing the extension portion 70 of the glass guide channel 60 onto the end cover 80.

[0077] (4) When the extension portion 70 of the glass guide channel 60 is installed onto the end cover 80, the extension portion 70 is pushed into the receiving space SP of the end cover 80. Therefore, when the extension portion 70 is pushed into the end cover 80, the inner engaging lip 78a of the extension portion 70 contacts the inner protrusion 86 of the end cover 80 from below, and the outer engaging lip 78b of the extension portion 70 contacts the window frame trim 40 from below. Moreover, after the extension portion 70 contacts the inner protrusion 86 and the window frame trim 40 of the end cover 80, it is difficult to push the extension portion 70 further in. Therefore, when the extension portion 70 of the glass guide channel 60 is installed onto the end cover 80, the door 10 can suppress excessive pushing of the extension portion 70.

[0078] (5) In the door 10, the extension portion 70 of the glass guide channel 60 contacts the outer engaging wall 83 and the inner engaging wall 82 of the end cover 80 via multiple lips and multiple ribs. Therefore, the door 10 can suppress the posture change of the extension portion 70 inside the end cover 80.

[0079] <Example of Change>

[0080] This embodiment can be modified as follows. This embodiment and the following modifications can be combined and implemented together without technical inconsistencies.

[0081] The shape of the extension portion 70 of the glass guide channel 60 can be appropriately modified. For example, the extension portion 70 may not have at least one of the inner rib 79a and the outer rib 79b. In addition, the extension portion 70 may not have at least one of the inner engaging lip 78a and the outer engaging lip 78b. Furthermore, the extension portion 70 may not have at least one of the base lip 74, the inner lip 75, and the outer lip 76.

[0082] In the glass guide channel 60, the inner rib 79a of the extended part 70 can contact the inner engaging wall 82 of the end cap 80. The outer rib 79b of the extended part 70 can contact the outer engaging wall 83 of the end cap 80, or it can contact the outer protrusion 87 of the end cap 80.

[0083] In the extension portion 70 of the glass guide channel 60, the shape of the covering lip 77 can be appropriately changed. The covering lip 77 can be any shape that can close the gap between the window frame trim 40 and the window frame decorative piece 50.

[0084] The end cap 80 may also not have at least one of the inner protrusion 86 and the outer protrusion 87.

[0085] In the end cap 80, the shapes of the inner protrusion 86 and the outer protrusion 87 can be appropriately modified. In addition, the positional relationship of the inner protrusion 86 and the outer protrusion 87 in the vertical direction Z can be appropriately modified.

[0086] The engagement method between the window frame trim 40 and the end cap 80 can be appropriately changed. For example, the rear end of the window frame trim 40 can be glued relative to the end cap 80.

[0087] Alternatively, the front end of the door 10 in the fully closed position may correspond to the rear end of the door opening, and the rear end of the door 10 in the fully open position may correspond to the front end of the door opening. For example, if the door 10 of the above embodiment is used as the front door, and the door of the above modified example is used as the rear door, the front door and the rear door open opposite each other when the vehicle is viewed from the width direction.

[0088] The door 10 can also be a sliding door that moves between a fully closed position and a fully open position by moving along the longitudinal direction of the vehicle. Alternatively, the door 10 can also be a door that moves between a fully closed position and a fully open position by rotating about an axis extending along the longitudinal direction of the vehicle. The door 10 can also be a door using other opening and closing methods.

[0089] <Summary of this implementation method>

[0090] The door includes: a door frame having a rear window frame, a front window frame, and an upper window frame, the rear window frame and the front window frame being spaced apart in the longitudinal direction and guiding the lifting and lowering of a movable panel, the upper window frame connecting the upper ends of the rear window frame and the upper ends of the front window frame in the longitudinal direction; a glass guide channel having a portion mounted on the rear side of the rear window frame, a portion mounted on the front side of the front window frame, and a portion mounted on the upper side of the upper window frame; a window frame trim strip disposed along the upper end of the door frame; a window frame trim piece covering the rear window frame at a position offset downward relative to the window frame trim strip; and an end cap mounted on the rear end of the window frame trim strip. The glass guide channel has an extension portion extending rearward from the rear end of the upper portion and held by the end cap, the extension portion including a closing portion that closes the window frame trim strip and the window frame trim piece.

[0091] In the door, the closing portion of the extended glass guide channel seals the gap between the window frame trim and the window frame trim. Therefore, even with the surface smoothing of the movable panel and the window frame trim, gaps between them can be suppressed. As a result, the door can prevent aesthetic deterioration caused by such gaps, or suppress wind noise during vehicle operation. Furthermore, the extended glass guide channel is held in place by an end cap covering the window frame trim. Therefore, no additional structure is needed to hold the extended glass guide channel in the door.

[0092] In the aforementioned vehicle door, preferably, the end cover has an inner engaging wall, an outer engaging wall, an inner protrusion, and an outer protrusion. The inner engaging wall and the outer engaging wall are positioned opposite each other with a gap in the thickness direction of the vehicle door. The inner protrusion protrudes from the inner engaging wall toward the outer engaging wall, and the outer protrusion protrudes from the outer engaging wall toward the inner engaging wall. The extended portion has an inner lip and an outer lip. The inner lip contacts the inner engaging wall and contacts the inner protrusion from above, and the outer lip contacts the outer engaging wall and contacts the outer protrusion from above.

[0093] In the extended portion of the glass guide channel, the inner lip not only contacts the inner engaging wall of the end cover but also contacts the inner protrusion of the end cover from above. Similarly, the outer lip not only contacts the outer engaging wall of the end cover but also contacts the outer protrusion of the end cover from above. Therefore, the door can prevent the extended portion of the glass guide channel from falling downward from the end cover.

[0094] In the aforementioned end cover of the vehicle door, preferably, the upper end of the inner protrusion is located below the upper end of the outer protrusion.

[0095] When the extension portion of the glass guide channel is installed onto the end cover, the extension portion is pushed into the space between the inner and outer engaging walls of the end cover. In this case, the extension portion is pushed into the end cover in an upward direction relative to the end cover as it moves inward toward the door. That is, when the extension portion is pushed into the end cover, the inner lip of the extension portion is difficult to engage with the inner protrusion. Because of this, in the above structure, the upper end of the inner protrusion is located below the upper end of the outer protrusion. Therefore, when the extension portion is pushed into the end cover, the inner lip of the extension portion easily engages with the inner protrusion of the end cover. As a result, the workability of installing the extension portion of the glass guide channel onto the end cover is improved.

[0096] In the aforementioned vehicle door, preferably, the lower end of the window frame trim is located below the lower end of the outer locking wall, and the extended portion has an inner locking lip and an outer locking lip, the inner locking lip contacting the inner protrusion from below, and the outer locking lip contacting the lower end of the window frame trim from below.

[0097] When the extended portion of the glass guide channel is installed onto the end cover, the extended portion is pushed into the space between the inner and outer engaging walls of the end cover. Therefore, when the extended portion is pushed in relative to the end cover, the inner engaging lip of the extended portion contacts the inner protrusion of the end cover, and the outer engaging lip of the extended portion contacts the window frame trim. Furthermore, after the extended portion contacts the inner protrusion of the end cover and the window frame trim, it is difficult to push the extended portion further in. Therefore, when the extended portion of the glass guide channel is installed onto the end cover, the door 10 can prevent excessive pushing of the extended portion.

[0098] In the aforementioned door, preferably, the extended portion has an inner rib and an outer rib, the inner rib contacting the inner engaging wall of the end cover, and the outer rib contacting one of the outer engaging wall of the end cover and the window frame trim.

[0099] In the door, the extended portion of the glass guide channel has multiple lips and ribs to serve as a structure for contacting the end cap and window frame trim. Therefore, the door can suppress the posture changes of the extended portion inside the end cap.
