Description

[Technical field]

[0001] The present invention relates to a vehicle door structure. [Background technology]

[0002] A typical vehicle door structure is configured to raise and lower the door glass of a vehicle door in the vertical direction. A single-rail type window regulator is known as a mechanism for raising and lowering this door glass. The single-rail type window regulator has a guide rail that extends in the vertical direction and a carrier plate.

[0003] The carrier plate holds the lower edge of the door glass and is slidably attached to the guide rail. The carrier plate moves up and down on the guide rail via a specified wire by the power of a motor unit located at the lower end of the guide rail. In this way, the single-rail window regulator can raise and lower the door glass in the vertical direction.

[0004] In the vehicle door structure of Patent Document 1, in a sedan-type vehicle in which the front pillars are tilted so as to recede, the front door sash and the roof sash form an obtuse angle, and the window glass, which corresponds to the shape of the door sash, is raised and lowered by a single-rail window regulator. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 6242120 Summary of the Invention [Problem to be solved by the invention]

[0006] In the vehicle door structure of Patent Document 1, the window glass has an obtuse angle portion that corresponds to the obtuse angle formed by the front sash and the roof sash, and furthermore, a glass run is in contact with the front edge of the window glass. The glass run is disposed continuously from the upper end to the lower end of the front sash and guides the raising and lowering of the window glass.

[0007] However, when a door glass having an obtuse angle is raised or lowered by a single-rail window regulator, the obtuse angle of the door glass may come into contact with and get stuck on the glass run, causing a malfunction of the glass lift. If this occurs, the door glass may be pressed strongly against the glass run when the door glass is raised or lowered, causing the glass run to tear, or the door glass may momentarily decrease in lift speed, causing the door glass anti-pinch device to malfunction and cause the door glass to rotate erroneously.

[0008] One possible measure to prevent glass lifting failures is to apply a lubricant such as silicone to the glass run, but this would significantly increase costs.In addition, even if a double-rail or X-arm window regulator were to be used instead of the single-rail type, the components would be larger than those of a single-rail window regulator, resulting in increased weight and reduced freedom of layout within the vehicle door.

[0009] In view of the above problems, the present invention has an object to provide a vehicle door structure that can suppress the jamming behavior of the door glass when the door glass is raised or lowered by a single-rail type window regulator. [Means for solving the problem]

[0010] In order to solve the above problems, a representative configuration of a vehicle door structure according to the present invention is a vehicle door structure including a door glass of a vehicle door and a single-rail type window regulator that raises and lowers the door glass in a vertical direction, the vehicle door structure further including a front glass run that contacts a front edge of the door glass, a rear glass run that contacts a rear edge of the door glass, and a roof glass run that connects upper ends of the front glass run and the rear glass run and forms an obtuse angle with the front glass run, the door glass has an obtuse angle portion that corresponds to the obtuse angle formed by the front glass run and the roof glass run, the window regulator includes a guide rail extending in a vertical direction, a carrier plate that is slidably attached to the guide rail and is pulled by a predetermined wire to slide in a vertical direction on the guide rail, a glass channel that extends in the front-rear direction of the vehicle and holds the lower edge of the door glass, and a protrusion attached to the carrier plate, the protrusion is rotatably fitted into the glass channel, and the glass channel rotates relative to the carrier plate with the protrusion as a fulcrum. Effect of the Invention

[0011] According to the present invention, it is possible to provide a vehicle door structure that can suppress the jamming behavior of the door glass when the door glass is raised or lowered by a single-rail type window regulator. [Brief description of the drawings]

[Diagram 3] FIG. 3 is a perspective view showing the window regulator of FIG. 2(a) as viewed from the outside of the vehicle. [Figure 4] 3A to 3C are diagrams illustrating behavior of a door glass in the vehicle door structure of FIG. 1B when the door glass is raised or lowered. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] A representative configuration of a vehicle door structure according to one embodiment of the present invention is a vehicle door structure including a door glass of a vehicle door and a single-rail type window regulator that raises and lowers the door glass in a vertical direction, the vehicle door structure further including a front glass run that contacts a front edge of the door glass, a rear glass run that contacts a rear edge of the door glass, and a roof glass run that connects upper ends of the front glass run and the rear glass run and forms an obtuse angle with the front glass run, the door glass has an obtuse angle portion that corresponds to the obtuse angle formed by the front glass run and the roof glass run, the window regulator includes a guide rail extending in a vertical direction, a carrier plate that is slidably attached to the guide rail and is pulled by a predetermined wire to slide in a vertical direction on the guide rail, a glass channel that extends in the front-rear direction of the vehicle and holds the lower edge of the door glass, and a protrusion attached to the carrier plate, the protrusion is rotatably fitted into the glass channel, and the glass channel rotates relative to the carrier plate with the protrusion as a fulcrum.

[0014] The window regulator of the above configuration has a carrier plate that slides up and down on the guide rail, as well as a glass channel that holds the lower edge of the door glass, and the glass channel rotates relative to the carrier plate, using a single protrusion attached to the carrier plate as a fulcrum.

[0015] Therefore, when the obtuse angle portion comes into contact with the front glass run during the raising and lowering of the door glass and the door glass is pushed by the front glass run, the glass channel rotates relative to the carrier plate, using one protrusion attached to the carrier plate as a fulcrum. As a result, the door glass rotates together with the glass channel relative to the carrier plate, and rotates around the center of gravity or the vicinity of the center of gravity of the door glass. As a result, not only does the obtuse angle portion of the door glass come into contact with the front glass run, but the corner of the rear lower end comes into contact with the rear glass run. This corner of the rear lower end is located diagonally to the obtuse angle portion and is the corner where the rear edge and the lower edge of the door glass intersect.

[0016] In other words, in the above configuration, when the obtuse angle portion comes into contact with the front glass run and the door glass rotates when the door glass is raised or lowered, the door glass comes into contact with the glass run at two points: the obtuse angle portion and the corner portion diagonally opposite the obtuse angle portion. Therefore, even if the obtuse angle portion of the door glass comes into contact with the front glass run, a moment that offsets the catching behavior is generated by the normal force and frictional force generated by the contact between the corner portion at the lower rear end and the rear glass run, and the catching behavior of the door glass can be suppressed.

[0017] This prevents the door glass from being pressed hard against the front glass run when the door glass is raised or lowered, causing the front glass run to tear, or prevents the door glass anti-pinch device from malfunctioning and erroneously reversing due to a momentary decrease in the raising and lowering speed of the door glass.

[0018] The above-mentioned protrusion is a roller, the carrier plate extends toward the outside of the vehicle toward the glass channel and has a pin that penetrates the roller to support the roller, the glass channel has a support portion that holds the lower edge of the door glass, and a rail that extends in the fore-and-aft direction of the vehicle and is attached to the underside of the support portion, the rail includes a side wall that faces the end of the pin, an upper wall that is bent from the upper edge of the side wall toward the inside of the vehicle, a lower wall that is bent from the lower edge of the side wall toward the inside of the vehicle, and a convex portion formed so as to convex from the side wall toward the outside of the vehicle, the end of the pin is located in the convex portion of the rail, and the roller is surrounded by the side wall, upper wall and lower wall of the rail and is supported by the pin to rotate within the rail.

[0019] In this way, the roller as a protrusion rotates while being supported by a pin within a rail surrounded by the side walls, upper wall, and lower wall of the rail extending in the vehicle front-rear direction of the glass channel. The rail has a C-shaped cross section formed by the side walls, upper wall, and lower wall. The pin is slidable in the vehicle front-rear direction relative to the rail. Therefore, the rail of the glass channel can not only rotate with respect to the carrier plate, but also move in the vehicle front-rear direction. Therefore, the support part that holds the lower edge of the door glass can not only rotate with the rail relative to the carrier plate, but also move in the vehicle front-rear direction. Furthermore, by forming a convex part on the side wall of the rail, the rigidity of the rail can be improved. Furthermore, the space of the convex part makes it possible to set the end of the pin large not only in the vertical direction but also in the vehicle width direction. This improves the force that clamps the roller, and the rattle of the roller can be suppressed. Furthermore, by the end of the pin being located on the convex part of the rail, it becomes easier to guide the rail so that the rail rotates with respect to the carrier plate and moves in the vehicle front-rear direction, and rattle during rotation and movement in the vehicle front-rear direction can be suppressed.

[0020] Therefore, when the obtuse angle portion comes into contact with the front glass run during the raising and lowering of the door glass and the door glass is pushed by the front glass run, the glass channel not only rotates with respect to the carrier plate but also moves toward the rear of the vehicle, rotating around the center of gravity of the door glass or near the center of gravity. This ensures that the corner portion diagonally opposite the obtuse angle portion of the door glass comes into contact with the rear glass run, generating a moment that offsets the jamming behavior, and thus sufficiently suppressing the jamming behavior of the door glass.

[0021] In addition, because the support and the rail of the glass channel overlap vertically, the rigidity in the vertical direction is increased, and the support force of the door glass can be improved. Furthermore, because the roller rotates within the rail surrounded by the side walls, upper wall, and lower wall of the rail, the position of the roller is restricted by the rail, and rattle can be eliminated.

[0022] The above-mentioned window regulator further has a pulley section attached to the upper end of the guide rail and around which a wire is wound, and a motor unit located at the lower end of the guide rail and which raises and lowers a carrier plate on the guide rail via the wire by the rotational force of a drum rotated by the regulator motor, the carrier plate has a first fixed portion which fixes one end of the wire wound around the pulley section, and a second fixed portion which fixes the other end of the wire which is wound around the drum of the motor unit and extends along the guide rail, and the roller is provided on the front or rear side of the vehicle relative to the first fixed portion and the second fixed portion.

[0023] In this way, the carrier plate is provided with a first fixing portion and a second fixing portion for fixing one end and the other end of the wire, respectively, so that the carrier plate can slide up and down on the guide rail by being pulled by the wire.

[0024] Furthermore, when the roller attached to the carrier plate is provided further forward of the first and second fixing parts, the roller is located forward of the center of gravity of the door glass. Therefore, the corner diagonally opposite the obtuse angle of the door glass is more reliably brought into contact with the rear glass run, generating a moment that offsets the catching behavior, thereby more sufficiently suppressing the catching behavior of the door glass. Even if the vehicle door structure is applied to a rear door and the roller is provided further rearward of the vehicle than the first and second fixing parts, the door glass is in contact with the glass run at two points, the obtuse angle and the corner diagonally opposite the obtuse angle, thereby more sufficiently suppressing the catching behavior of the door glass.

[0025] The roller, the first fixed portion and the second fixed portion are located closer to the shorter vertical side of the door glass than the center of gravity of the door glass, which makes it possible to suppress vibrations of the door glass when it is raised and lowered.

[0026] The roller is a damping material that dampens vibrations. If the roller is made of a damping material such as rubber, the roller can absorb vibrations even if the obtuse angle portion comes into contact with the front glass run when the door glass is raised or lowered. This can prevent the door glass entrapment prevention device from malfunctioning and erroneously reversing. EXAMPLES

[0027] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific values ​​shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same functions and configurations are given the same reference numerals to avoid repeated explanations, and elements not directly related to the present invention are not shown.

[0028] Fig. 1 is a diagram showing a vehicle door structure 100 according to an embodiment of the present invention. The vehicle door structure 100 in Fig. 1(a) is applied to a front door on the right side of a vehicle, and shows a state seen from the inside of the vehicle. Fig. 1(b) is a diagram showing a main part of the vehicle door structure 100 in Fig. 1(a).

[0029] In the following drawings, the front and rear directions of the vehicle are indicated by arrows FRONT and BACK, the left and right directions of the vehicle width are indicated by arrows LEFT and RIGHT, and the up and down directions of the vehicle are indicated by arrows UP and DOWN. In the following description, the vehicle door structure 100 on the right side of the vehicle in FIG. 1 is illustrated, but the present invention is not limited to this, and the present embodiment may be applied to a front door on the left side of the vehicle, or a rear door on the right side or left side of the vehicle.

[0030] As shown in Fig. 1(a), the vehicle door structure 100 includes a door glass 104 of a vehicle door 102. The vehicle door 102 has a door outer panel 106 that serves as an exterior, and a door inner panel 108 that is connected to the door outer panel 106 from the inside of the vehicle. The door glass 104 can be stored between these panels. Fig. 1(b) shows the vehicle door structure 100 in a state where the door inner panel 108 in Fig. 1(a) is omitted. It has become like this.

[0031] The door glass 104 is a so-called power window that is electrically raised and lowered. The vehicle door structure 100 includes a single-rail window regulator 110 shown in FIG.

[0032] The door glass 104 is surrounded by a door sash 112, which is a window frame shown in Fig. 1(a). The door sash 112 is provided with a front glass run 114, a rear glass run 116, and a roof glass run 118 shown in Fig. 1(b), and the door glass 104 moves up and down along the front glass run 114 and the rear glass run 116. These glass runs are elastic sealing members made of resin or rubber, and seal the gap between the door sash 112 and the door glass 104.

[0033] The front glass run 114 is in contact with a leading edge 120 of the door glass 104. The rear glass run 116 is in contact with a trailing edge 122 of the door glass 104. The roof glass run 118 connects an upper end 124 of the front glass run 114 and an upper end 126 of the rear glass run 116, and as shown in FIG. 1(b), its leading end 128 is inclined so as to form an obtuse angle with the upper end 124 of the front glass run 114. The leading edge 120 and the trailing edge 122 of the door glass 104 are vertical sides of the door glass 104, and the leading edge 120 is shorter than the trailing edge 122.

[0034] For this reason, the door glass 104 has an obtuse angle portion 130 that corresponds to the obtuse angle formed by the front glass run 114 and the roof glass run 118. Here, when the door glass 104 having the obtuse angle portion 130 is raised or lowered, the obtuse angle portion 130 of the door glass 104 may come into contact with and get stuck on the front glass run 114, which may cause a failure in raising or lowering the glass.

[0035] Therefore, the vehicle door structure 100 employs a configuration that can suppress the jamming behavior of the door glass 104 when the door glass 104 is raised or lowered by the single-rail type window regulator 110.

[0036] 1(b), the window regulator 110 has a guide rail 132, a carrier plate 134, a glass channel 136, a pulley unit 138, and a motor unit 140. The guide rail 132 is installed on the door inner panel 108 and extends in the vertical direction.

[0037] The carrier plate 134 is slidably attached to the guide rail 132, and is pulled by a wire 142 to slide vertically on the guide rail 132. The glass channel 136 extends in the front-rear direction of the vehicle and holds a lower edge 144 of the door glass 104.

[0038] The pulley unit 138 is attached to an upper end 146 of the guide rail 132, and the wire 142 is wound around it. The motor unit 140 is located at a lower end 148 of the guide rail 132, and has a regulator motor 150 and a drum 152. The motor unit 140 raises and lowers the carrier plate 134 on the guide rail 132 via the wire 142 by the rotational force of the drum 152 rotated by the regulator motor 150.

[0039] Fig. 2 is a diagram showing a main part of the window regulator 110 in Fig. 1(b). Fig. 2(a) is an enlarged view of a part of the window regulator 110 in Fig. 1(b). Fig. 2(b) is a cross-sectional view taken along line AA in Fig. 2(a). Fig. 3 is a perspective view showing the window regulator 110 in Fig. 2(a) as viewed from outside the vehicle.

[0040] The carrier plate 134 has a first fixing portion 154 and a second fixing portion 156 shown in Fig. 2(a). The first fixing portion 154 fixes one end 142a of the wire 142 wound around the pulley portion 138. The second fixing portion 156 fixes the other end 142b of the wire 142. The other end 142b of the wire 142 is wound around a drum 152 of the motor unit 140 shown in Fig. 1(b) and extends along the guide rail 132.

[0041] The window regulator 110 further has a roller 158 as one protrusion shown in Fig. 2(b). Also, the carrier plate 134 has a pin 159 that supports the roller 158 as shown in Fig. 2(b). The roller 158 has a cylindrical shape and is attached to the carrier plate 134. Note that the roller 158 may be made of a damping material such as a rubber member that dampens vibrations.

[0042] The glass channel 136 has a support portion 160 and a rail 162. The support portion 160 and the rail 162 extend in the front-rear direction of the vehicle and are stacked vertically as shown in Figures 2(a) and 3(a). Note that Figure 3(a) shows the window regulator 110 without the door glass 104.

[0043] 2(b), the support part 160 includes side walls 164a, 164b facing the lower edge 144 of the door glass 104, and a bottom wall 166 connecting the side walls 164a, 164b, which form a groove part 168 that holds the lower edge 144 of the door glass 104. As a result, the lower edge 144 of the door glass 104 is held in the groove part 168 of the support part 160, and is further fixed by a bottom channel 170 made of adhesive or rubber.

[0044] The rail 162 is attached to the underside of the support portion 160, and includes a side wall 172 located on the vehicle exterior side, an upper wall 174, a lower wall 176, and a protruding portion 178 as shown in FIG. 2(b). The upper wall 174 is a wall that is bent from an upper edge 172a of the side wall 172 toward the vehicle interior side. The lower wall 176 is a wall that is bent from a lower edge 172b of the side wall 172 toward the vehicle interior side. In this manner, the side wall 172, the upper wall 174, and the lower wall 176 form a C-shaped cross section of the rail 162. The protruding portion 178 is a portion that is formed so as to protrude from the side wall 172 toward the vehicle exterior side.

[0045] The roller 158 is fitted into the rail 162 surrounded by the side wall 172, the upper wall 174 and the lower wall 176 of the rail 162 as shown in FIG. 2(b). The pin 159 supporting the roller 158 includes a shaft portion 180 shown in FIG. 2(b) and FIG. 3(b). Note that FIG. 3(b) shows a state in which the glass channel 136 and the roller 158 are omitted from the window regulator 110 of FIG. 3(a). The shaft portion 180 of the pin 159 extends toward the outside of the vehicle toward the inside of the rail 162 of the glass channel 136 as shown in FIG. 2(b) and penetrates the roller 158. The roller 158 is fitted into the rail 162 and is slidable in the front-rear direction of the vehicle relative to the rail 162. This allows the glass channel 136 to move in the front-rear direction of the vehicle relative to the carrier plate 134.

[0046] The roller 158 is rotatably attached to the carrier plate 134 via a gap 184 (see FIG. 2(b)) around the shaft portion 180 of the pin 159. However, the present invention is not limited to this, and the roller 158 having a cylindrical shape may be attached to the shaft portion 180 of the pin 159 so as not to rotate. In this case, the roller 158 does not rotate with respect to the carrier plate 134. The roller 158 is rotatably fitted in the rail 162 of the glass channel 186.

[0047] Therefore, the glass channel 160 can not only move in the longitudinal direction of the vehicle relative to the carrier plate 134 with the pin 159 as an axis in accordance with the rotation of the roller 158, or can rotate along the cylindrical shape of the roller 158 when the roller 158 itself does not rotate. In other words, the glass channel 160 can not only rotate in the longitudinal direction of the vehicle relative to the carrier plate 134 with the roller 158, which is a protruding part attached to the carrier plate 134, as a fulcrum.

[0048] In addition, the protrusion 178 is formed on the side wall 172 of the rail 162, thereby improving the rigidity of the rail 162. Furthermore, the end 182 of the shaft 180 of the pin 159 is located on the protrusion 178 of the rail 162. Therefore, the space of the protrusion 178 makes it possible to set the end 182 of the shaft 180 of the pin 159 large not only in the vertical direction but also in the vehicle width direction. This improves the force that pinches the roller 158, and can suppress rattling of the roller 158. Furthermore, since the end 182 of the shaft 180 of the pin 159 is located on the protrusion 178 of the rail 162, it becomes easier to guide the rail 162 so that the rail 162 of the glass channel 136 rotates relative to the carrier plate 134 or moves in the vehicle longitudinal direction, and rattling during rotation or movement in the vehicle longitudinal direction can be suppressed.

[0049] 2(a), the roller 158 is provided on the vehicle front side of the first fixing portion 154 and the second fixing portion 156 of the carrier plate 134. Furthermore, as shown in FIG. 1(b), the carrier plate 134 is disposed on the vehicle front side of the center of gravity G, which is the center of area of ​​the door glass 104. Therefore, the roller 158 rotatably attached to the carrier plate 134, and the first fixing portion 154 and the second fixing portion 156 provided on the carrier plate 134 are also set on the vehicle front side of the center of gravity G of the door glass 104.

[0050] Fig. 4 is a diagram showing the behavior of the door glass 104 of the vehicle door structure 100 in Fig. 1(b) when it is raised or lowered. Fig. 4(a) and Fig. 4(b) respectively show the behavior of the door glass 104 when it is raised by the above-mentioned window regulator 110 and the window regulator 110A of the comparative example.

[0051] The window regulator 110A of the comparative example has a carrier plate 134A. The carrier plate 134A has a pair of holders 188a, 188b that hold the lower edge 144 of the door glass 104. This allows the carrier plate 134A to slide up and down on the guide rail 132 together with the pair of holders 188a, 188b in the window regulator 110A of the comparative example. However, the window regulator 110A does not have the glass channel 136 and rollers 158 described above.

[0052] When the door glass 104 is raised by the window regulator 110A, if the obtuse angle portion 130 comes into contact with the front glass run 114 at point B, a downward force indicated by an arrow C acts on the obtuse angle portion 130. The door glass 104 is then pushed by the front glass run 114 and rotates counterclockwise around point D as indicated by an arrow E. This rotation center D is the fitting position of the carrier plate 134A and the guide rail 132 as shown in the figure. Therefore, when the door glass 104 rotates, only the obtuse angle portion 130 comes into contact with the front glass run 114, and other portions do not come into contact with the glass run.

[0053] In other words, when the door glass 104 is raised or lowered by the window regulator 110A of the comparative example, the door glass 104 contacts the glass run at only one point, and a jamming behavior of the door glass 104 occurs due to the moment balance between the normal force and the frictional force.

[0054] 4(a) has a carrier plate 134 that slides up and down on the guide rail 132, a glass channel 136 that holds the lower edge 144 of the door glass 104, and a roller 158. Furthermore, the glass channel 136 rotates relative to the carrier plate 134 in accordance with the rotation of one roller 158 attached to the carrier plate 134, or along the cylindrical shape of the roller 158. As described above, since the roller 158 is slidable in the front-rear direction of the vehicle relative to the rail 162, the glass channel 136 can also move in the front-rear direction of the vehicle relative to the carrier plate 134.

[0055] In the vehicle door structure 100, when the obtuse angle portion 130 contacts the front glass run 114 at point B while the door glass 104 is rising, a downward force indicated by an arrow C acts on the obtuse angle portion 130. As a result, the door glass 104 is pushed by the front glass run 114, and the glass channel 136 rotates relative to the carrier plate 134 as indicated by arrows F and H. In addition to this rotational motion, the glass channel 136 slides toward the rear of the vehicle relative to the carrier plate 134 as indicated by an arrow I.

[0056] As a result, the door glass 104 rotates counterclockwise around point J as indicated by arrow K. This rotation center J is at or near the center of gravity G of the door glass 104 shown in FIG. 1(b). As a result, not only does the obtuse angle portion 130 of the door glass 104 come into contact with the front glass run 114, but a corner 190 at the rear lower end of the door glass 104 comes into contact with the rear glass run 116 at point L. This corner 190 at the rear lower end is a corner where the rear edge 122 and lower edge 140 of the door glass 104 intersect, and is located diagonally from the obtuse angle portion 130.

[0057] That is, in the vehicle door structure 100, when the obtuse angle portion 130 comes into contact with the front glass run 114 and the door glass 104 rotates during raising and lowering of the door glass 104, the door glass 104 comes into contact with the glass run at two points, the obtuse angle portion 130 and the corner portion 190 diagonally positioned to the obtuse angle portion 130. Therefore, even if the obtuse angle portion 130 of the door glass 104 comes into contact with the front glass run 114, a moment that offsets the jamming is generated by the normal force and frictional force generated by the contact between the corner portion 190 at the lower rear end and the rear glass run 116, and the jamming behavior of the door glass 104 can be suppressed.

[0058] This prevents the door glass 104 from being pressed hard against the front glass run 114 when the door glass 104 is raised or lowered, causing the front glass run 114 to tear, or prevents the anti-pinch device of the door glass 104 from malfunctioning and reversing erroneously due to an instantaneous decrease in the raising and lowering speed of the door glass 104.

[0059] Thus, in the vehicle door structure 100 , the roller 158 is attached to the carrier plate 134 , and further, the roller 158 is rotatably fitted within the rail 162 of the glass channel 136 .

[0060] Therefore, when the obtuse angle portion 130 comes into contact with the front glass run 114 and the door glass 104 is pressed against the front glass run 114 during lifting and lowering of the door glass 104, the glass channel 136 can rotate relative to the carrier plate 134 along with the rotation of the roller 158 or along the cylindrical shape of the roller 158. In the glass channel 136, the support portion 160 that holds the lower edge 144 of the door glass 104 also rotates together with the rail 162.

[0061] This ensures that the corner 190 diagonally opposite the obtuse angle portion 130 of the door glass 104 comes into contact with the rear glass run 116, generating a moment that offsets the jamming, thereby sufficiently suppressing the jamming behavior of the door glass 104.

[0062] In addition, since the glass channel 136 has the support portion 160 and the rail 162 overlapping each other vertically, the rigidity in the vertical direction is increased, and the supporting force for the door glass 104 can be improved.

[0063] Furthermore, roller 158 is surrounded by side wall 172, upper wall 174, and lower wall 176 that form the C-shaped cross section of rail 162, and is fitted into rail 162, so that roller 158 rotates within rail 162. Therefore, the position of roller 158 is restricted by rail 162, and rattle can be eliminated.

[0064] The carrier plate 134 is provided with a first fixing portion 154 and a second fixing portion 156 for respectively fixing one end 142a and the other end 142b of the wire 142. Therefore, the carrier plate 134 can slide up and down on the guide rail 132 by being pulled by the wire 142.

[0065] Furthermore, the roller 158 rotatably attached to the carrier plate is provided further forward of the first fixing portion 154 and the second fixing portion 156, and is therefore located forward of the center of gravity G (see FIG. 1(b)) of the door glass 104. This makes it possible to suppress vibrations caused when the door glass 104 is raised and lowered. Even if the roller 158 is provided further rearward of the first fixing portion 154 and the second fixing portion 156, it is possible to suppress vibrations caused when the door glass 104 is raised and lowered.

[0066] Further, the roller 158, the first fixing portion 154, and the second fixing portion 156 are set closer to the shorter vertical side of the door glass 104 (the vehicle front side) than the center of gravity G of the door glass 104. Therefore, when the obtuse angle portion 130 contacts the front glass run 114 when the door glass 104 is raised or lowered, the door glass 104 pressed by the front glass run 114 is likely to rotate around the center of gravity G, and the jamming behavior of the door glass 104 can be sufficiently suppressed. Even if the vehicle door structure 100 is applied to a rear door and the roller 158 is provided closer to the shorter vertical side of the door glass of the rear door (the vehicle rear side) than the first fixing portion 154 and the second fixing portion 156 and is positioned on the obtuse angle side of the center of gravity G, the door glass 104 contacts the glass run at two points, the obtuse angle portion 130 and the corner portion 190, and the jamming behavior of the door glass 104 can be more sufficiently suppressed.

[0067] Furthermore, if the roller 158 is made of a damping material such as a rubber member that dampens vibrations, the vibrations can be absorbed even if the obtuse angle portion 130 comes into contact with the front glass run 114 when the door glass 104 is raised or lowered. This makes it possible to prevent the trap prevention device of the door glass 104 from malfunctioning and erroneously reversing. Furthermore, unintended slippage between the rail 162 and the roller 158 can be suppressed, thereby suppressing vibrations caused by friction. This makes it possible to reliably perform the desired rotation of the door glass 104, which can suppress the jamming behavior of the door glass 104.

[0068] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such an embodiment. It is clear that a person skilled in the art can think of various modifications or alterations within the scope of the claims, and it is understood that these also naturally belong to the technical scope of the present invention.
