The present invention relates to an automobile door structure that prevents the generation of flapping noise.

2. Description of the Related Art Conventionally, a door glass disposed on a door of an automobile moves up and down by an operation of a window regulator using an X-shaped arm, for example, as shown in FIG.
As shown in FIG. 5, the X-shaped window regulator 50 is provided in a space between a door outer panel 65 of the automobile door and a door inner panel (not shown for explanation).
The window regulator 50 includes an X-shaped arm 53 in which two arms 51 and 52 are pivotally connected to each other at a substantially central position in the longitudinal direction thereof. One end (referred to as a tip) is slidably provided on a rail 54 extending in the horizontal direction. The rail 54 is provided on the lower end side of the door glass 70, and the lower side of the door glass 70 is supported by the X-shaped arm 53 via the rail 54.

The other end (referred to as the rear end) of one of the X-shaped arms 53 is slidable along a laterally extending rail 55 fixed near the center of a door inner panel (not shown). It is connected to.
The other end (referred to as the rear end) of the other arm 51 is rotatably held by a base plate 63 fixed near the center of the door inner panel (not shown) and next to the rail 55. Yes. The base plate 63 is provided with a rotating shaft 62, and the rear end side of the arm 51 and the fan-shaped driven gear 60 are connected to the rotating shaft 62.
Gear teeth are formed on the fan-shaped arc portion of the driven gear 60. When the motor 61 is driven, the gear 61 of the motor 61 is engaged with the gear teeth, so that the driven gear 60 is rotated. Is rotated about the rotation shaft 62.

For example, when the arm 51 rotates about the rotary shaft 62 and the tip end side thereof rotates upward, the arm 52 connected in an X shape also moves on the rail 55 while the rear end side moves on the rail 55. It rotates as an axis, and its tip side moves upward.
Thereby, the rail 54 is maintained in a parallel state, and the door glass 70 is raised while the load of the door glass 70 is received by the two arms 51 and 52.
Further, when the arm 51 rotates about the rotary shaft 62 and the tip side thereof rotates downward, the arm 52 connected in an X shape also moves on the rail 55 while the rear end side moves on the rail 55. It rotates as a shaft, and its tip side moves downward.
Thereby, the rail 54 is maintained in a parallel state, and the door glass 70 is lowered while the load of the door glass 70 is received by the two arms 51 and 52.

By the way, in the window regulator 50 configured as described above, when the door glass 70 is lowered and fully opened, the door glass 70 includes the front door frame 65a and the rear door. It is supported by a connecting portion between the frame 65b and the rail 54 on the lower side of the glass. That is, the door glass 70 is supported on the three sides of the lower side and the left and right sides.
However, when the door glass 70 is fully opened to open and close the door, even if the three sides of the door glass 70 are supported as described above, there is a problem that abnormal noise (flapping noise) is generated due to vibration of the door glass 70. there were.

In order to solve the above problem, Patent Document 1 discloses a configuration in which the lower end of the window glass is held by a glass holder 80 made of a resin foam as shown in FIG.
The glass holder 80 is provided in the lower part of the space between the door outer panel 65 and the inner panel 66 and includes a fitting recess 81 for holding the lower end of the window glass 70. At that time, the lower end of the glass is fitted into the fitting recess 81 so as to suppress vibration when the door is opened and closed.

In the conventional window regulator 50 described above, when the door glass 70 is lowered to a half-open state, the door glass 70 has a belt shown in FIG. 5 in addition to the lower side and the left and right sides. The outer belt molding portion (not shown) of the line 65c is also supported.
However, the outer belt molding of the belt line 65c has a weak holding force with respect to the door glass 70, and the door glass 70 sometimes flutters in the vehicle width direction even in a half-open state.

In order to deal with such a problem, in Patent Document 2, a guide lip 76 is provided in a glass run 75 (refer to the cross-sectional view of FIG. 7) of the door sash 65d. The structure which touches is disclosed.
That is, the guide grip 76 is elastically contacted with the tip of the door glass 70 to suppress the vibration of the door glass 70, and when the door is closed with the door glass 70 half open, no flapping noise is generated. Yes.
By providing the glass run 75 having such a guide lip 76 on the door frame 65b on the rear side, even when the door glass 70 is fully opened, vibration of the door glass 70 is suppressed when the door is opened and closed. Generation of sound can be prevented.
