In this case, as shown in FIG. 8, the normal door glass 100 has a structure in which the upper end portion thereof is inclined toward the vehicle inner side from the lower end portion thereof. Therefore, the lifting force F applied to the lower end side of the door glass 100 generates a component force F2 on the vehicle outer side (arrow OUT side) in addition to the ascending force F1, and the lower end side of the door glass 100 is displaced to the vehicle outer side by this component force F2. Tend to.

Thus, when the lower end side of the door glass 100 is displaced to the vehicle outer side (arrow OUT side) as indicated by a two-dot chain line and the degree thereof is relatively large, the vehicle of the draining channel 130 attached to the upper opening 120 of the door panel 110 is used. A gap t1 is generated between the inner member 140 and the inner member 140.
As described above, when the gap t1 is generated between the inner side surface of the door glass 100 and the member 140 on the vehicle inner side (arrow IN side) of the draining channel 130, the intrusion of wind noise into the vehicle increases, and in some cases Finger penetration may occur and improvements are desired.
The present invention has been made paying attention to the above-described problems, and provides a door glass support structure that can prevent the occurrence of a gap between the door glass and the upper opening of the door panel when the door glass is fully closed. For the purpose.

  According to a fourth aspect of the present invention, in the door glass support structure according to the first, second, or third aspect, the input position where the lifting force from the window regulator of the glass support member is input is an extended surface of the glass center of the door glass. It is characterized by overlapping.

  According to the door glass support structure of claim 1, when the door glass reaches the fully closed position, the protrusion of the glass support member abuts on the outer panel side, so that the displacement of the door glass toward the outside of the vehicle is prevented. Since it can suppress, generation | occurrence | production of the clearance gap between the drainage channel etc. which comprise the vehicle inner side surface of a door glass and the inner edge of the upper opening of a door panel can be suppressed, the penetration | invasion of a wind noise into a vehicle can be prevented and a passenger | crew's finger | toe can be prevented from entering.

  According to the door glass support structure of the second aspect, since the protrusion comes into contact with the reinforcement which is the reinforcing member, the displacement of the door glass to the outside of the vehicle can be reliably received.

  According to the door glass support structure of the third aspect, since the protrusion is formed integrally with the holder, the number of parts and the cost can be reduced.

  According to the support structure of the door glass according to claim 4, the input position where the lifting force from the window regulator is input overlaps the extended surface of the glass center of the door glass, that is, the input position is an extension of the glass center of the door glass. Since it is not offset from the surface, the displacement of the door glass's attitude to the outside of the vehicle and the torsional input to the door glass when raising and lowering can be reduced, and the raising and lowering resistance can be reduced, especially when the protrusion and the outer panel are in contact with each other Excessive pressing of the protrusion can be reduced.

  A door window 17 is formed by the belt line portion at the upper end of the door panel 1, the front and rear vertical portions 201, 201 and the upper sash portion 202 of the sash 2. The front and rear vertical parts 201 and 201 and the upper sash part 202 have a U-shaped cross section, and a U-shaped cross section is a main part inside the run channel 18 which is a buffer member for holding the door glass 3. It is worn.

  As shown in FIG. 3, a window regulator 4 that constitutes an elevating mechanism for the door glass 3 is fastened to the main part of the inner panel 5. The window regulator 4 is provided at a window motor 19 that is driven in accordance with an occupant's opening / closing instruction, a link portion 22 that decelerates the rotational force and replaces it with a peristaltic displacement of the X-type operation arm 21, and a peristaltic end of the operation arm 21. And a roller 24 for applying a lifting force to the rail channel 23 (rail member) on the door glass 3 side.

As shown in FIG. 1, the door glass 3 guided so as to move up and down by the sash 2 is integrally joined with a pair of glass support members 25 in the vicinity of both end portions at the lower end edge thereof.
As shown in FIGS. 1 and 6, the glass support member 25 includes a metal rail channel 23 (rail member) that contacts the roller 24 (see FIG. 3) on the operation arm 21 side of the window regulator 4, and the rail channel 23. And a holder 14 including a main part 27 integrally formed with the lower fastening part 26 and the lower fastening part 26 and integrally joined to the lower edge of the door glass 3.

The rail channel 23 is a laterally long member having a U-shaped cross section in which the roller 24 at the projecting end of the rail channel 23 comes into roller contact within a predetermined sliding range L1 (see FIG. 5) as the operating arm 21 swings. As shown in FIGS. 5 and 6, the left and right ends of the rail channel 23 are formed as U-shaped cross-sections as coupling ends, and the center portion is in addition to the U-shaped cross section, and the upper and lower flange portions that are bent upward and downward from the protruding ends 231 is formed. The upper and lower flange portions 231 prevent the roller 24 from being detached from the rail channel 23.
The holder extension members 31 of the pair of left and right holders 14 are overlapped on the left and right coupling end portions 232 and 233 of the rail channel 23, and through holes 28 (see FIG. 6) are respectively formed therein.

As shown in FIG. 6, the embedded nut 29 is integrally embedded in the lower fastening portion 310 of the holder extending member 31. A fastening bolt 26 inserted through the through hole 28 is screwed into the screw hole 291 of the embedded nut 29, whereby the left and right ends of the rail channel 23 and the left and right holders 14 are fastened.
The lower edge of the door glass 3 and the vicinity of the left and right ends thereof are integrally coupled to the main portion 27 of the left and right holders 14, whereby the rail channel 23 is integrally fastened to the lower edge of the door glass 3.
As shown in FIG. 6, the holder 14 has a U-shaped longitudinal groove 271 in the center and a main part 27 that is a resin-molded thick member, and the main part 27 is resin-molded integrally with the main part 27 by resin welding. And a holder extension member 31.
The lower edge portion of the door glass 3 is fitted into the U-shaped vertical groove 271 of the main portion 27 and is integrally coupled to each other with an adhesive.

  As shown in FIG. 6, the vehicle width direction position P <b> 1 (substantially input position) of the rail channel 23 is set so as to substantially overlap the downward extending surface fc of the door glass center surface 32. Accordingly, the upward and downward lifting force F from the roller 24 is set to be applied to the door glass 3 almost accurately. Particularly, since the input position P1 is not offset from the glass center of the door glass 3, the displacement of the posture of the door glass 3 toward the outside of the vehicle and the torsional input to the door glass 3 during raising and lowering can be reduced, and the raising and lowering resistance can be reduced. The durability of the regulator 4 and the run channel on the sash side can be improved.

Next, the holder 14 is formed with a vehicle outer wall surface 312 projecting from a side portion 311 of the holder extension member 31, and three longitudinally projecting ribs 15 project at substantially equal intervals on the vehicle outer wall surface 312. Has been. Each rib 15 is formed so as to be positioned on the outermost side of the vehicle in a state where the holder 14 is coupled to the door glass 3.
As shown in FIG. 6, front and rear vehicle facing walls 13 are formed at two locations near the front and rear ends of the upper outer reinforcement 11 (belt line reinforcement). Front and rear vehicle facing surfaces fg are formed on the two front and rear vehicle facing walls 13. When the door glass 3 rises and reaches the fully closed position Pc (see FIG. 1), the front-rear interior facing surface fg is positioned so as to face the rib 15 on the holder 14 side integral with the door glass 3 via a predetermined gap ts. Pre-formed.

This gap ts is set to be sufficiently smaller than the maximum width T of the displacement toward the vehicle outer side (arrow OUT side in FIG. 1) in the vehicle width direction on the lower side of the door glass 3.
Here, with respect to the door glass 3 side, the X-type operating arm 21 that swings up and down and the other members of the window regulator 4 are located on the vehicle inner side (arrow IN side in FIG. 3). In this case, the shape and position of the X-type operation arm 21 are set in advance so that the X-type operation arm 21 does not interfere with the door glass 3 when it is swung up and down.

The lifting force F from the window regulator 4 arranged in this way is applied to the vehicle width direction position P1 (substantially input position) of the rail channel 23 located on the vehicle outer side (arrow OUT side in FIG. 1) from the window regulator 4. Here, as shown in FIG. 1, the upper end of the door glass 3 is inclined toward the vehicle inner side from the lower end thereof, and the lifting force F applied to the vehicle width direction position P <b> 1 (substantially input position) from the roller 24 is substantially the door. If it is applied in the direction of the extended surface fc of the glass 3, the main part of the lifting force F is a vertical component force Fh, and a part works as a vehicle external component force Fs.
When the door glass 3 receives the lifting force F from the window regulator 4 and comes into contact with the upper part of the sash 2, that is, at the fully closed position Pc that reaches the closed state, Slightly increase.

  The component force Fs in the vehicle exterior direction at this time moves from the position a to the position b as shown in FIG. 6 and displaces the holder 14 below the door glass 3 in the vehicle exterior direction (arrow OUT side in FIG. 1). At this time, as shown in FIGS. 1 and 6, the rib 15 located at the vehicle outer end of the holder 14 is relatively in contact with the two front and rear vehicle facing walls 13 on the upper outer reinforcement 11 arranged opposite to each other. They are displaced by a small gap ts (see FIG. 6) and contact. Even if the vehicle component Fs in the vehicle outward direction of the lifting force F from the side of the window regulator 4 is further applied from the window regulator 4 by the ribs 15 coming into contact with the front and rear vehicle facing walls 13, the outside of the vehicle below the door glass 3. The displacement to is reliably suppressed.

As a result, as shown in FIG. 1, a gap is generated between the vehicle inner side surface of the door glass 3 and the piece-shaped inner seal portion 162 of the draining channel 16 attached to the vehicle inner edge portion 9 of the upper opening 7. Can be regulated.
That is, here, when the door glass 3 reaches the fully closed position Pc and is held in a state in which no displacement occurs in the vehicle width direction Y, the two positions on the rib 15 on the holder 14 side and the upper outer reinforcement 11 are preliminarily maintained. The clearance t1 between the front and rear vehicle interior facing walls 13 is set to an interval within a range in which it is possible to reliably control the generation of a clearance between the drainage channel 16 and the piece-shaped inner seal portion 162.
It is assumed that the door glass 3 is held at the fully closed position Pc while the vehicle equipped with the door D having the support structure for the door glass 3 in FIG. 1 is traveling.

In this case, since the rib 15 on the holder 14 side maintains a contact state with the in-vehicle facing wall portion 13 of the upper outer reinforcement 11, there is a gap between the piece-like inner seal portion 162 of the draining channel 16 and the door glass 3. It does not occur, and wind noise can be reliably prevented from entering the vehicle. In addition, since no gap is formed between the piece-like inner seal portion 162 of the draining channel 16 and the door glass 3, it is possible to prevent the occupant's fingers from entering the portion and prevent the intrusion, and the occupant's safety. Can be secured.
Further, since the holder 14 is integrally formed with the rib 15 (projection) located at the outer end of the vehicle, the number of parts can be reduced and the cost can be reduced.

  Furthermore, the input position P1 to which the lifting force F from the window regulator 4 is input overlaps with the extension surface fc of the glass center surface 32 of the door glass 3, that is, the input position P1 is the extension surface of the glass center surface 32 of the door glass 3. Since it is not offset with fc, the displacement of the posture of the door glass 3 toward the vehicle exterior and the torsion input to the door glass 3 at the time of raising and lowering are reduced, and the raising and lowering resistance can be reduced. In this case, in particular, since the displacement of the posture of the in-car facing wall portion 13 of the upper outer reinforcement 11 and the door glass 3 reaching the position facing the same is small, the preset rib 15 (projection) and the in-car facing wall The gap of the portion 13 can be set relatively small, and accordingly, the amount of displacement of the door glass 3 to the outside of the vehicle can be made smaller, and the wind noise can be prevented from entering the vehicle more reliably. Further, drag at the time of contact between the rib 15 and the in-vehicle facing wall portion 13 and excessive pressing of the rib 15 can be reduced.

  Furthermore, since two (plurality) holders 14 are used, the degree of freedom of the arrangement positions of the ribs 15 (protrusions) that come into contact with the interior wall 13 of the upper outer reinforcement 11 (fixing member) can be increased. More precisely, the generation of a gap between the inner side surface of the door glass 3 and the draining channel 16 forming the inner edge of the upper opening 7 of the door panel 1 can be reliably suppressed over the entire glass surface, and wind noise can be prevented from entering the vehicle. , Can prevent the intrusion of occupants' fingers.

  In the above description, the holder 14 has three vertically projecting ribs 15 (see FIG. 4) provided on the outer wall surface 312 of the holder extension member 31 at regular intervals. As shown in FIG. 7A, a triangular prism shaped protrusion 15a may be formed. Or you may form the cylindrical protrusion 15b as shown in FIG.7 (b). Even when these protrusions 15a and 15b are formed, the same effect as the rib 15 of FIG. 1 can be obtained.

Furthermore, as shown in FIG. 7C, a protrusion that can variably adjust the protrusion amount h1 may be formed.
In this case, the holder 14 with the protruding amount variable portion 40 is formed by embedding a nut 41 in the holder extending member 31. The embedded nut 41 is screwed with a bolt 43 having a resinous cylindrical protrusion 15c on the head. In addition, in this case, a washer 44 for adjusting the protrusion amount is sandwiched between the columnar protrusion 42 and the outer wall surface 312 of the holder extension member 31. The bolt 43 and the washer 44 constitute the protruding amount variable portion 40 here. In this case, by adjusting the thickness of the washer 44, the gap ts between the cylindrical protrusion 15c and the in-vehicle facing surface fg (see FIG. 6) of the upper outer reinforcement 11 (fixing member) can be finely adjusted.

  Thereby, an individual error of the door D, that is, an assembly error between products can be absorbed, and an optimal gap setting can be performed. As a result, it is possible to reliably suppress the occurrence of a gap between the interior surface of the door glass 3 and the draining channel 16 that forms the inner edge of the upper opening 7 of the door panel, prevent wind noise from entering the vehicle, Can be prevented.

In the above description, the main portion 27 and the holder extending member 31 of the holder 14 are welded and integrated. However, the main portion 27 and the holder extending member 31 may be integrally formed with resin.
In the above description, the holder 14 is integrally coupled to the lower end of the door glass 3 at two front and rear positions, and the rail channel 23 is integrally coupled via the two holders 14. A structure in which one main portion and two holder extending members are integrated may be formed so that the door glass and the rail channel are integrally coupled (not shown). In this case, ribs are formed as protrusions at two locations before and after the integrated holder.
