Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is directed to a door window opening/closing device for a front door of a cab-over type vehicle, in particular, a door window opening/closing device for a front door of a cab-over type vehicle. , relates to a technique for opening and closing a door window that is stored in the front part of the window glass storage section.

(Prior Art) Conventionally, the door windows provided on the front door of a cab-over type vehicle have generally been a front-rear sliding window as shown in FIG. 9 and an elevating window as shown in FIG. 10. .

In the former sliding window, the front and rear window glasses 70, 7
1 slides in the front and back direction to open and close, there is no need to provide a window glass storage inside the door D, and therefore the height H of the window opening 72 can be set large; On the other hand, in order to completely open the rear window glass 71, it is necessary to secure enough space to draw the rear window glass 71 toward the front half of the window opening 72. It is constrained to have to be formed into a square shape. If the window opening 72 has a rectangular shape as described above, the shape of the door D itself, that is, the shape from the front edge of the door to the upper edge of the door, needs to be rectangular. This also affects the angle of inclination of the glass, making it difficult to maintain a large inclination angle, resulting in large air resistance during driving, and problems such as insufficient upward visibility from the driver's seat.

Regarding the latter elevating window, there is no problem with the inclination angle of the front shield glass described above, but since it is an elevating type, it is necessary to provide a window glass storage section 73 inside the door D. In this case, a wheel arch portion 74 is formed in a substantially arc shape from the rear edge to the lower edge of the door D along the front tire house of the vehicle body. Width will be limited. In this way, the window glass storage section 7
When the depth width of window 3 is limited, the vertical width of the window glass 75 is naturally limited, which also limits the height of the window opening 76, and the lower edge 77 (waistline) of the window opening 76 is limited. You will have to set it upwards. In addition, if the window opening 7 is opened as shown in FIG.
Even if the height of the window glass 75 is increased, the height of the window glass 75 must be increased accordingly.
Therefore, even if the window glass 75 is lowered to the lowest position, the upper edge of the window glass 75 will protrude beyond the waistline 77, and in this case, increasing the height of the window opening 76 is meaningless. As mentioned above, the presence of the wheel arch 74 makes the waistline 7
If 7 is set upward, the side visibility from the driver's seat will be narrowed, and it will be difficult to rest your elbows on the waistline while driving. There was a problem in which it was said that if the upper body was stretched out, it would be difficult to maintain an upright posture, making it difficult to check behind the vehicle, which could lead to an accident.

(Object of the Invention) The present invention has been made to solve the problems of the conventional art, and its purpose is to solve the problems of the conventional sliding window and the wheel arch part. In contrast to elevating windows where the height of the window opening cannot be made large due to the presence of lift windows, the inclination angle of the front shield glass can be made large with the present invention, and the waistline can be lowered even though the height of the window opening is made large. To provide a door window opening/closing device for a front door of a cab-over type vehicle.
