The inside guide part of the channel will be placed at the position where the opening edge of the channel and the outside guide part of the channel are to be fixed by hemming, and the inside guide part of the channel will interfere when setting the hemming type. Become. That is, when applying a bending force to the window opening edge portion of the outer panel of the hemming type, the bending force can be applied only from an oblique direction from the window opening center side with respect to the bending direction, and as a result, the hemming portion Had a possibility that the bending angle could not reach the point where it was completely joined to the channel.

Further, in order to bend the hemming portion to a state where it is completely joined to the channel, it is necessary to divide the hemming die and change the direction with a cam or the like. there were.

Further, as another conventional structure for achieving a flash surface, there is a third structure disclosed in Japanese Utility Model Laid-Open No. 62-65311.
The ones described in the figure are known.

In this conventional structure, the opening edge portions for both windows of the inner panel and the outer panel are joined to each other, and a step portion for joining the opening edge portions for both windows and inserting and lifting the window glass is formed on the outer panel. The edge of the window glass is supported from the inside of the vehicle by the window opening edge of the outer panel, and the edge of the window glass is supported from the outside of the vehicle by the finisher fixed to the outer surface of the outer panel. there were.

However, in such a conventional structure, the finisher is different in material from the outer panel,

It is not necessary to turn back the grass run provided to cover the glass run, so that the turned-back portion of the grass run is covered by the outer panel 20.
The panel outer surface 23 is formed to be almost flat because a step portion for preventing the panel outer surface 23 from protruding is not required.

Thus, in addition to the flat outer surface 23 of the outer panel 20, the glass run 40
However, the outer surface of the outer panel 20 is formed so as not to cover the outer surface of the outer panel 20, and the outer side portion 41 that contacts the inner peripheral surface of the outer panel 20 is thinly formed. The step between the outer surface 51 and the panel outer surface 23 of the outer panel 20 is small.

Further, in the outer panel 20 and the inner panel 30, since all the parts forming the front frame 103, the rear frame 104, and the upper frame 105 are integrally press-molded, the front frame 103, the rear frame 104, and The number of assembling steps such as joining work can be reduced as compared with a case where the upper frame 105 is separate.
Furthermore, since the outer panel 20 is integrated, the dividing line is not exposed on the outer surface 23 of the panel, which is good in appearance.

Further, since the engagement step portions 113 and 123 of the channel 10 and the engagement lips 41 and 42 of the grass run 40 are engaged with each other, the grass run 40 can be reliably prevented from coming off. Further, since the channel 10 is formed by stacking two panels of the vehicle inside member 11 and the vehicle outside member 12, the rigidity of the window frame 106 is increased.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and the present invention can be applied even if there is a design change or the like within a range not departing from the gist of the present invention. included.

For example, in the embodiment, the hinge type door is used for getting on and off, but it may be applied to a sliding door, a back door, or the like. Further, in each of the front side frame, the rear side frame, and the upper side frame, the channel 10 is provided between the inner panel 30 and the outer panel 20, and the channel 10 is formed by the vehicle inside member 11 and the vehicle outside member 12. 12 and 12 may be formed by hemming.

(Effects of the Invention) As described above, in the vehicle window frame structure of the present invention, the flash surface is set such that the outer surface of the window glass and the outer surface of the outer panel are arranged substantially in the same plane. At the same time, the hemming part of the outer panel can be easily formed into a bent state where it is completely joined to the vehicle outer guide part without any hindrance, and without dividing lines on the outer panel surface of the outer panel. As a result, it is possible to obtain an effect that the window frame can be integrally viewed and the appearance can be further improved.

In addition to the above effects, in the embodiment, since the engagement step portions 113 and 123 of the channel 10 and the engagement lips 41 and 42 of the grass run 40 are engaged with each other,
It is possible to reliably prevent the grass run 40 from coming off.
