[Problems to be solved by the invention]
By the way, usually, when the elevating window of the vehicle door is at the lowest position where it descends to the lowest, the upper edge of the elevating window is covered by the upper end of the door panel.
[0006]
However, in the structure in which the window area is enlarged by using the step structure as described above, since the outside portion of the vehicle compartment at the upper end of the door panel is stepped, the window is retracted when the window is lowered to the lowest state. The upper edge is exposed to the outside (outside) of the vehicle as it is. That is, the upper edge of the lifting window is exposed to the outside.
[0007]
For this reason, when the window is stored, an object can easily come into contact with the upper edge of the elevating window from the outside. In particular, since most of the elevating windows are formed of a glass member, the upper edge of the elevating window may be damaged by an applied impact or load.
[0008]
In addition, the upper part of the door panel has a stepped part outside the cabin, so that the upper edge of the elevating window must be exposed in order to prevent the upper edge from being exposed. It is necessary to reduce the area of the opening under the window to enhance the visibility of the camera, and it is difficult to achieve compatibility with the visibility.
[0009]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle door structure capable of preventing damage to an elevating window and ensuring sufficient lateral visibility of a door.
[0010]
[Means for Solving the Problems]
According to the first aspect of the present invention, in order to achieve the above object, an intermediate window portion is provided in which an upper end portion of a door panel portion is cut out and a window portion formed by a window frame portion is extended downward. Is configured to move up and down from the lowest position where the upper edge is located between the intermediate window and the window to the highest position where the window is closed. A structure is adopted in which a partition is provided so as to partition between the window and the intermediate window while covering the edges from both sides in the vehicle interior and exterior.
[0011]
With this configuration, the upper edge of the elevating window when the window is retracted at the most lowered position is protected by the partition, both the upper edge on the vehicle interior side and the upper edge on the outer side of the vehicle interior. The edge does not have to come into contact with external objects. In addition, since the window area of the intermediate window portion can be independently determined by forming the partition portion, the window area can be enlarged. That is, the visibility of the side of the door is improved while preventing the breakage of the window.
[0012]

An elongated partition section 30 is provided along the upper end of the door panel section 13 which does not have a partition. As shown in FIGS. 2 and 3, the partition portion 30 straddles the outside of the arms 16 and 17 sandwiching the hoistway 24 of the elevating window panel 25, for example, between panel surfaces on the outer side of the arms 16 and 17. The garnish, for example, a belt line garnish 31, is combined with a slender interior portion 32 that also straddles the inside of the arms 16 and 17, for example, between the panel surfaces on the inner side of the arms 16 and 17. Specifically, for example, as shown in FIGS. 2 and 3, the belt line garnish 31 is provided between the arm portions 16 and 17 (in the front-rear direction), following the upper end of the lifting window panel 25 at the lowest position. ), And a structure having a weatherstrip 34 attached to the upper end of the back surface of the decorative portion 33 is used. In addition, the decorative surface (design surface) 35 formed on the outer surface of the decorative portion 33 faces outside the vehicle compartment. The interior part 32 has, for example, a cross section extending between the arm portions 16 and 17 (front-back direction) following the upper end of the elevating window panel 25 at the lowest position as shown in FIGS. A substantially U-shaped elongated reinforce member 37, a weatherstrip 38 attached to the upper end of a wall on the back side of the reinforce member 27, and a trim covering the front side (inside the vehicle) of the reinforce member 37 The structure combined with the portion 39 is used. The belt line garnish 31 and the interior part 32 (the reinforcement member 37 and the trim part 39) are arranged in parallel so that the weather strip 34 and the weather strip 38 face each other with the hoistway 24 interposed therebetween. Further, the decorative portion 33, the reinforcement member 37, and the trim portion 38 all have a width dimension enough to cover the upper edge portion of the elevating window panel 25 at the lowest position. At both ends of the reinforcement member 37, substantially L-shaped seats 41 are formed so as to overlap the front and rear panel portions of the arms 16 and 17, respectively. As shown in FIG. 2, the belt line garnish 31 and the reinforcement member 37 are connected to each of the arm portions 16 and 17 from both ends of the reinforcement member 37 by avoiding the run channel 8. (The outer panel part 6 and the inner panel part 9) are penetrated and screwed into the boss part 42 formed on the back surface of the decorative part 33 so that the arm parts 16 and 17 can be detached from the indoor and outdoor side parts, respectively.
