As shown in these drawings, the door of this automobile has an outer plate 4 and an inner plate 5 forming an inner space 3 in which a door glass 2 of a door window 1 is lowered, and a further gap between the inner plate 5 and the inner plate 5. An internal partition plate 7 and a door trim 8 forming a space 6, a door handle 10 arranged in the gap space 6 and operated via an operation port 9 of the door trim 8, a door locking mechanism 11 at a side edge of the door, In order to connect the door handle 10 and the door lock mechanism 11, a link rod 13 and the like arranged via the gap space 6, the through hole 12 of the internal partition plate 7, the internal space 3 and the like are provided.

FIG. 2 shows a conventional door of this type. (1) is a schematic perspective view of a main part with a door trim 8 removed, and (2) is an enlarged plan sectional view of the main part. Although it is a drawing, as shown in these drawings, the through hole 12 provided in the internal partition plate 7 is conventionally provided in a considerably large size. That is, the link rods 13 are arranged so as to be slightly inclined with respect to the inner partition plate 7, the door trim 8, the outer plate 4 and the like, so that the internal partition plate is not hindered in the operation of the link rod 13. The through hole 12 provided in No. 7 has a margin compared with the diameter of the link rod 13 and the like, and is provided with a considerably large diameter.

[0004]

[Problems to be solved by the device]

 By the way, the following problems have been pointed out in such a conventional example. That is, when traveling, a pressure difference is generated between the inside and the outside, and an air flow is easily formed from the outside 14 to the inside 15 (see FIG. 4). Therefore, in a conventional automobile door, the gap 16 between the upper door glass 2 and the outer plate 4 and the inner plate 5 (see FIG. 4), and further, the water between the lower outer plate 4 and the inner plate 5 When air blows into the internal space 3 from the outdoor 14 through a vent hole (not shown) or the like, the wind blows the large gap 17 (see FIG. 2) between the through hole 12 and the link rod 13 described above. Through which it flows into the gap space 6. Then, such a wind is blown into the room 15 through a gap at a mounting portion on the periphery of the door trim 8, a gap at the operation port 9 of the door trim 8, and the like. As described above, when the vehicle is traveling, the air outside the room 14 enters the room 15 as wind, so that cold air or warm air enters the room 15 especially in the winter when the room 15 is being heated or the summer when the room 15 is being cooled. It was a problem.

In view of such circumstances, the present invention has been made to solve the problems of the above-mentioned conventional example, and a predetermined closing member is provided between the through hole of the inner partition plate and the link rod. In this way, it is an object of the present invention to propose a vehicle door that can reliably prevent air from entering the room from the outside when driving.

[0006]

[Means for Solving the Problems]

 The technical means of the present invention for achieving this object are as follows. That is, the door of this automobile forms an inner space in which a door glass of a vertically openable door window can descend, and an outer plate and an inner plate which are arranged to face each other, and a gap space is further formed between the inner plates. Internal partition plate and door trim, a door handle arranged at a predetermined position in the gap space and operated from the inside of the door through an operation port provided in the door trim, and attached to the side edge on the opening / closing side of the door. A door lock mechanism, a link rod arranged through the gap space, the through hole of the internal partition plate, the internal space, etc. to connect the door handle and the door lock mechanism, and a through hole of the internal partition plate. And a linking member which is provided between the link rods and which covers and seals between the link rods.

[0007]

[Action]

 Since the present invention comprises such means, it works as follows. When traveling, air flows easily from the outside to the inside of the room. However, in the present invention, even if the air blows into the internal space from the outside through the gap between the door glass and the outer plate or the inner plate, the air does not flow into the gap space. That is, since the gap between the through hole of the inner partition plate and the link rod is covered and sealed by the expandable and contractible closing member, such wind can be reliably prevented from flowing into the gap space. Therefore, the wind is not blown into the room, and the invasion of air from the outside to the room is reliably prevented.

[0008]

【Example】

 Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings. FIG. 1 shows an embodiment of the present invention, in which (1) is a schematic perspective view of a main part with a door trim 8 removed, and (2) is an enlarged plan sectional view of the main part. Hereinafter, description will be given with reference to FIG. 1 in addition to FIGS. 3 and 4 described above. This automobile door has the following door window 1, outer plate 4, inner plate 5, inner partition plate 7, door trim 8, door handle 10, door locking mechanism 11, link rod 13, closing member 18, and the like. It becomes.

First, referring to FIG. 3 and FIG. 4, the door window 1 is provided with a single door glass 2 that is vertically closed, and is arranged at the upper part of the door. The outer plate 4 and the inner plate 5 are also referred to as outer panel and inner panel, respectively, and form an inner space 3 in which the door glass 2 can descend via a gap 16 in the upper part, and are arranged facing each other inside and outside to form a bag structure. . Further, the internal partition plate 7 and the door trim 8 further form a gap space 6 with respect to the inner plate 5. That is, the center of the inner plate 5 is largely opened via the stepped portion, and is tightly closed by an inner partition plate 7 also called a door inside hole cover. The inner space 3 is formed by closely partitioning the outer plate 4 on the 14 side, and a concave space is formed on the room 15 side. This concave space is a plate-like shape attached from the room 15 side. It is closed by a door trim 8 to form a gap space 6. The door trim 8 is attached to the inner plate 5 at the peripheral edge thereof, but in consideration of the ease of inspection and maintenance of the internal link rods 13 and the like and the attachment cost, the attachment structure is easier to attach and detach than before. There is often a gap between the inner plate 5 and the inner plate 5 that is not hermetically sealed.

Next, the door handle 10 is arranged at a predetermined position in the gap space 6 as an inside handle, and is operated from the room 15 side through the operation port 9 provided in the door trim 8. Further, the door lock mechanism 11 is attached to the side edge opposite to the side edge where the door is hinged to the cab, that is, the side edge on the opening / closing side of the door, and correspondingly, to the lock receiving side attached to the cab side. The door can be locked with (not shown). The link rod 13 is arranged laterally through the gap space 6, the through hole 12 of the internal partition plate 7, the internal space 3 and the like so as to connect the door handle 10 and the door lock mechanism 11 to each other. Since the link rod 13 is arranged in this way, it is inevitably tilted structurally, and from the gap space 6 side to the inner space 3 side, that is, although it is horizontal in the horizontal direction, to the room 15 side. It is slightly inclined between the outdoor sides 14 (see FIGS. 1 and 4), and is slightly moved in the lateral direction by operating the handle of the door handle 10. Therefore, such a through hole 12 through which the link rod 13 penetrates is provided with a large diameter with a margin so as not to hinder the operation of the link rod 13. In many cases, the through hole 12 is in the shape of a horizontally elongated hole. There is a large gap 17 between it and 13 (see Fig. 1).

The closing member 18 is disposed between the through hole 12 of the internal partition plate 7 and the link rod 13 as described above, covers the gap 17 between them and seals the same, and can absorb the operation of the link rod 13. It consists of a flexible member (see Fig. 1). As such a closing member 18, for example, a substantially lantern-shaped bellows member is used, and its tip end is closely joined to the penetrating link rod 13 and its base end is a through hole. 12 It is closely joined to the inner partition plate 7 around it by welding or the like. The closing member 18 may be integrally formed with the internal partition plate 7.

Since the present invention is configured as described above, it is as follows. First, when the vehicle is traveling, a pressure difference is generated between the inside and the outside, and air flows easily from the outside 14 to the inside 15. However, in the automobile door of the present invention, the gap 16 between the door glass 2 of the upper door window 1 and the outer plate 4 and the inner plate 5 (see FIG. 4), and further the lower outer plate 4 and the inner plate 5 Even if the air blows from the outside 15 into the inside space 3 through the drain holes (not shown) between the plates 5, the wind does not flow into the gap space 6. That is, the large gap 17 between the through hole 12 provided in the internal partition plate 7 that divides the internal space 3 and the gap space 6 and the link rod 13 is covered and sealed by the expandable closing member 18. (See Figure 1). Therefore, the air blown into the internal space 3 as described above is reliably prevented from flowing into the gap space 6. Therefore, even if there is a gap in the mounting location on the periphery of the door trim 8 and the operation port 9, the air blown into the internal space 3 in this way is reliably blocked by the internal partition plate 7 and the closing member 18. Therefore, such wind does not blow into the interior 15, and the invasion of air from the exterior 14 into the interior 15 during traveling or the like is reliably prevented.

[0013]

[Effect of the device]

 As described above, the vehicle door according to the present invention exhibits the following effects by providing the predetermined closing member between the through hole of the inner partition plate and the link rod. In other words, when a car is traveling, air is not blown from the outside to the inside, and air is reliably prevented from entering the inside from the outside, especially in the winter when the room is heated or the summer when the room is cooled. Ingress of cold or warm air is avoided. In this way, the effects of the present invention are remarkably large, such as the problems existing in this type of conventional example are eliminated.
