Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a door window opening/closing device for a front door of a cab-over type vehicle, and particularly to a door window opening/closing device for a front door of a cab-over type vehicle, in particular a wheel arch formed at the rear of a terrace compartment where the window glass is a window. The present invention relates to a technique for opening and closing a door window that is stored in the front part of the window glass storage part while avoiding the front part of the window glass storage part.

(Prior Art) Conventionally, the door windows installed on the front door of a cab-over type vehicle are generally a sliding window in the front and rear direction as shown in Fig. 9, and an elevating window as shown in Fig. 10. be.

In the former case of double-sliding windows, the front and rear windows are opened and closed by sliding the laths 70 and 71 in the front and rear directions, so there is no need to provide a window glass storage inside the door D', and therefore the window opening 72
However, in order to completely open the rear window glass 71, it is necessary to create enough space to draw the rear window glass 71 toward the front half of the window opening 72. The necessary force to ensure 1 arises, and therefore the window opening 72
is constrained to have no choice but to form a rectangular shape.

If the shape of the upper window opening 72 is rectangular, 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 inclination angle of the windshield 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. do.

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.
The depth width of the window glass storage section 73 is limited by the presence of the window glass storage section 73. As described above, when the depth width of the window glass storage section 73 is limited, the vertical width of the window glass 75 is naturally limited, and this also limits the height of the window opening 76. The lower edge 77 (waistline) must be set upward. Incidentally, even if the height of the window opening 76 is increased as shown in FIG. Even if the window glass 75 is lowered to the maximum, the upper edge of the window glass 75 still protrudes from the waist line 77.
In this case, it is meaningless even if the height of the window opening 76 is greater than 1. As mentioned above, if the waistline 77 is set upward due to the presence of the wheel arch 74, the side visibility from the driver's seat will be narrowed, and it will also be difficult to rest your elbows on the waistline when driving. Not only will it become
When fabricating the back of a car, there was a problem in that it was difficult to maintain a posture such as leaning out of the window opening, making it difficult to check the rear of the car, which could lead to an accident.

(Object of the Invention) The present invention has been made to solve the problems of the conventional art. In contrast to elevating windows where the height of the window opening cannot be made large due to the presence of windows, the present invention allows the front shield glass to have a large inclination angle, and also lowers the waistline while increasing the height of the window opening. The object of the present invention is to provide a door window opening/closing device for a front door of an over-the-counter type shore.

(Structure of the Invention) That is, in order to achieve the above-mentioned object, a door window opening/closing device for a front door of a cab-over type vehicle according to the present invention is attached to a door opening of a vehicle body so as to be openable and closable, and has a door outer panel and a door inner panel.
