Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door sash which guides a rear edge of a door glass which moves in a vertical direction of a vehicle body and extends in a vertical direction of the vehicle body, and a door inner to which a lower end portion of the door sash is connected. The present invention relates to a structure of a rear door including a panel.

[0002]

2. Description of the Related Art As a conventional rear door structure, in particular, as a mounting structure of a door sash for guiding the vertical movement of a door glass, there is a structure as shown in FIGS. 5 and 6, for example.
That is, in the rear door structure shown in these figures, the door sash 2 is attached to the inner panel 10 constituting the rear door 1 via the V-shaped bracket 3.

[0003] More specifically, a corner portion of the inner panel 10 on the rear side of the vehicle body is formed in an arch shape corresponding to the shape of a wheel house. The bracket 3 is connected to the mounting portion 11 formed so as to protrude by a bolt 30. The upright portion 31 of the bracket 3 protruding from the mounting portion 11 has a U-shaped cross section and is open frontward.
Is connected to the lower end portion of the housing by appropriate means such as screws or bolts, or spot welding.

[0004]

However, in the above rear door structure, the bracket 3 and the inner panel 10 are connected at a position offset from the door sash 2 to the rear side of the vehicle body. For this reason, the bracket 3 is likely to vibrate or oscillate in the vehicle width direction, that is, in the direction indicated by the arrow a or b in FIG. In particular, when the rear door is strongly closed, the impact causes the bracket 3 to largely swing in the vehicle width direction. In such a case, since the door sash 2 is open frontward, the door glass 4 may come off.

[0005] In a sports car type vehicle, the door sash 2 is placed on the rear side of the vehicle body in order to improve the appearance by narrowing the area behind the door opening defined by the door sash 2. Tends to be deployed. However, the above-mentioned door opening is often trapezoidal in shape expanding downward (see FIG. 1), and the more the door sash 2 is arranged on the rear side of the vehicle body, the more vertically the rear edge of the door glass becomes. The dimensions must be set small. If the vertical dimension of the rear edge of the door glass is set to be small, the area of the door glass that is inserted into and guided by the door sash 2 becomes small. For this reason, in a vehicle in which the door sash 2 is disposed on the rear side of the vehicle body, the door glass may be more likely to come off due to the vibration caused by the opening and closing of the rear door.

The present invention has been conceived in view of the above circumstances, and enables the door glass to be properly maintained even when the rear door is strongly closed. That is the subject.

[0007]

DISCLOSURE OF THE INVENTION In order to solve the above problems, the present invention employs the following technical means.

That is, according to the present invention, a door sash that guides the rear edge of the door glass that moves in the vertical direction of the vehicle body and extends in the vertical direction of the vehicle body, and the door inner to which the lower end of the door sash is connected. A rear door structure including a panel, wherein the door sash is connected to the door inner panel at a portion of the door sash in a vehicle width direction. .

In the above configuration, the lower end of the door sash is connected to the inner panel directly or via a bracket, but the connecting portion of the inner panel is a portion of the door sash in the vehicle width direction. Therefore, the door sash is configured to be hard to oscillate in the vehicle width direction. Therefore, in the above configuration, even if the rear door is strongly closed and a strong impact is transmitted to the door sash, the door sash does not greatly swing in the vehicle width direction. There is no need to worry about the door glass coming off. In particular, in a vehicle in which the door sash is arranged on the rear side of the vehicle body to improve the appearance of the vehicle, the effect is more remarkably exhibited. Thus, in the rear door structure according to the present invention, the guide state of the door glass can be favorably maintained.

[0010] Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the accompanying drawings.
