The cover 16c has a length in the front-rear direction sufficient to cover the weather seal 15j of the lift resin glass 15, and the lift resin glass 15 has guide walls 21a1, 22a1 of the upper and lower division bars 21, 22. And the cover 16c of the fixed resin glass 16 extends forward. When the ascending / descending resin glass 15 moves up and down, the weather seal 15j slides on the inner surface of the cover 16c.

  According to the fixing structure of the fixed resin glass 16, since the fixed edge 16d is covered with the guide portion 21a of the upper division bar 21 and is not exposed when viewed from the inside of the vehicle, it is difficult to touch with a hand and the appearance is good. Further, since the shape of the fixed resin glass 16 is simple and easy to mold, and the cover portion 16c also serves as a guide for the flange portion 15f at the rear end of the elevating resin glass 15, the number of components can be reduced. Further, the elevating resin glass can be guided by a part of the fixed resin glass while reducing the width of the division bar in the vehicle width direction.

  In FIG. 22, the length of the fixed edge 16d of the fixed resin glass 16 is shortened to form a gap with the bottom wall of the guide portion 21a having a U-shaped cross section. This is an embodiment in which the portion 15f) is a large-sized portion extending into the gap (approaching the guide wall 21a2 of the upper division bar 21). In other words, the flange portion 15f of the elevating resin glass 15 is located inside the fixed edge 16d. According to this embodiment, the space | interval of the guide walls 21a1 and 21a2 before and behind the upper division bar 21 can be made small (the upper division bar 21 can be reduced in size).

  The characterizing portion of the present invention lies in the relational structure of the rear door elevating resin glass 15, the fixed resin glass 16 and the upper division bar 21 having the overall structure described above. That is, the fixed resin glass 16 is provided with a cover portion 16c located on the outer surface of the division bar 21 on the upper division bar 21 side of the main body portion 16a located in the rear opening 13b. The fixed edge 16d provided at the boundary between the cover 16c extends along the inner surface of the guide wall 21a2 behind the upper division bar 21 and is fixed. For this reason, the guide part 21a of the upper division bar 21 and the fixed edge 16d of the fixed resin glass 16 constitute a guide part of the flange part 15f (gear part 15g) of the lift resin glass 15, and the lift resin glass 15 is I can guide you. Since the weather seal 15j of the elevating resin glass 15 slides on the inner surface of the covering portion 16c, a part of the fixed resin glass 16 can be used as a guide for the elevating resin glass 15. Further, when viewed from the inside of the vehicle, the boundary portion (joint) between the fixed resin glass 16 and the upper division bar 21 is not seen, and the appearance is excellent, and it is difficult to touch with the hand.

  The relationship between the retaining hooks 15a and 15b at the front end portion of the elevating resin glass 15, the guide groove 12e and the notch 12d of the vertical frame portion 12a, and the structure around the division bar assembly 20 is a preferable one for guiding the elevating resin glass 15. Although it is a form, these show an example and this invention is not limited to this. It is not essential that the division bar is divided into upper and lower parts, and a drive mechanism for raising and lowering the elevating resin glass 15 is merely an example.
