  The outer frame 82 and the second outer frame 92, which are substantially L-shaped, are disposed so as to face each other, so that the outer frame 82 and the second outer frame 92 have a substantially rectangular shape. The tip of the second outer flange portion 92c is located on the extension line EL of the outer flange portion 82c.

  Referring also to FIG. 1, the window frame portion 80 and the second window frame portion 90 are provided closer to the driver's seat 12 than the vehicle width center line C <b> 1 of the vehicle body, and the second window frame portion 90 is more than the window frame portion 80. It is provided on the driver's seat 12 side. The effect of the present invention will be described with reference to the following figure.

  As shown in the comparative example in FIG. 6A, the window frame portion 180 having a hat-shaped cross section has a larger width B <b> 1 because the flange portions 182 c and 183 c are arranged along the door window panel 165. The window frame portion 180 hinders the field of view from the vehicle compartment In to the outside of the vehicle. If the width of the window frame portion 180 is large, the field of view is narrowed.

  On the other hand, as shown in the embodiment of FIG. 6C, the inner flange portion 83 c and the outer flange portion 82 c extend in a direction orthogonal to the surface of the door window panel 65. Thereby, width B2 of the window frame part 80 can be made small. Therefore, a wider field of view can be secured as compared with the case where the flange portions 82c and 83c are extended along the panel surface. That is, B1> B2.

  As shown in the comparative example of FIG. 6B, an external force F may be applied to the door window panel 165 from the outside. This external force acts to tilt the window frame 180 toward the passenger compartment. As the height H1 of the window frame portion 180 is smaller, the window frame portion 180 easily falls toward the passenger compartment.

  On the other hand, as shown in the embodiment of FIG. 6 (d), since the flange portions 82c and 83c extend in the direction in which the external force F is transmitted, the height H2 of the window frame portion 80 is increased and falls. Stiffness in the direction is increased. As a result, deformation (falling) of the window frame 80 can be suppressed. That is, H1 <H2.

  Referring also to FIG. 5, an outer flange portion 82c is formed at the tip of the side wall 82b extending in the direction orthogonal to the end of the panel mounting wall 82a. That is, the side wall 82 b and the outer flange portion 82 c extend in a direction orthogonal to the door window panel 65. Thereby, the rigidity in the falling direction is further increased.

  In addition, the outer frame 82 and the second outer frame 92 that are substantially L-shaped are arranged so as to face each other, so that the outer frame 82 and the second outer frame 92 have a substantially rectangular shape. The part exposed in the passenger compartment 25 has a substantially rectangular shape, and a high appearance can be obtained. The width of the second window frame portion 90 can be accommodated in the width of the window frame portion 80.

  Further, the portion where the second inner flange portion 93c and the second outer flange portion 92c are joined to each other is located closer to the vehicle compartment 25 than the portion where the inner flange portion 83c and the outer flange portion 82c are joined to each other. Yes. When viewed from inside the passenger compartment 25, the second inner flange portion 93c and the second outer flange portion 92c extending along the panel surface of the door window panel 65 extend in a direction perpendicular to the door window panel surface. The inner flange portion 83c and the outer flange portion 82c can be covered. By covering with a member extending along the door window panel surface, the design in the passenger compartment 25 can be enhanced.

  In addition, the tip of the second outer flange portion 92c is located on the extension line EL of the outer flange portion 82c. The second inner flange portion 93c and the second outer flange portion 92c extending along the panel surface of the door window panel 65 can be suppressed to the minimum necessary length. Thereby, high visibility can be ensured.

  Referring also to FIG. 3, the second window frame portion 90 is provided in the tailgate 40 attached to the rear surface of the vehicle body 11, the opening 50 is formed in the tailgate 40, and the door 60 is attached. . Here, the portion where the second inner flange portion 93c and the second outer flange portion 92c are joined to each other is located closer to the vehicle compartment 25 than the portion where the inner flange portion 83c and the outer flange portion 82c are joined to each other. ing. That is, since the second window frame 90 extends to a position farther from the door window panel 65 than the window frame 80, the second window frame 90 is closed more than the closed cross-sectional area of the window frame 80. A larger area can be secured. The tailgate 40 is a member that supports the door 60, and higher rigidity is required. By ensuring a large closed cross-sectional area of the second window frame portion 90 provided in the tailgate 40, the rigidity of the tailgate 40 can be increased.

  Referring to FIGS. 1 and 5, the window frame portion 80 and the second window frame portion 90 are provided closer to the driver's seat 12 than the vehicle width center line C1 of the vehicle body. For a driver who sits at a position offset from the center of the vehicle width, the center position of the vehicle width is an easily visible part. In other words, the window frame portion 80 and the second window frame portion 90 are provided so as to avoid a portion that is likely to enter the driver's field of view. By avoiding a part that easily enters the driver's field of view, the driver's field of view can be favorably secured. The same applies to the third outer flange portion 96 and the third inner flange portion 97.

7 and 8, the operation while the vehicles 10 and 110 are traveling will be described.
As shown in the comparative examples of FIGS. 7A and 8A, when the window frame portions 180 and 190 extend in the center of the vehicle width, the window frame portions 180 and 190 travel rearward. Most of the vehicle OC overlaps. Since it overlaps most, it is difficult for the occupant to visually recognize the other vehicle OC through the room mirror 118. In particular, if the distance between the vehicle 110 and another vehicle OC traveling behind is increased, the other vehicle OC may completely overlap the window frame portions 180 and 190 and may not be visible.

  It should be noted that the area shown by diagonal lines between the lines extending from the room mirror 118 shown in FIG. 7A is an area that can be confirmed by the room mirror 118. That is, the area between the areas indicated by diagonal lines is an area in which the field of view is blocked by the window frame portions 180 and 190.

  As shown in the embodiment of FIGS. 7B and 8B, the window frame portion and the second window frame portions 80 and 90 arranged on the right side (driver's seat side) of the vehicle body 11 are rear mirrors. Block a part of the field of view. However, since the window frame portion and the second window frame portions 80 and 90 are moved to the right side, the other vehicle OC traveling behind the vehicle 10 can be confirmed by the room mirror 18.

  In addition, as shown in FIG. 7C, when the other vehicle OC is traveling in the outer lane with reference to the driver's seat, the side vehicle 19 can confirm the following vehicle OC. it can.
