Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is directed to a door window opening/closing device in a front door of a cab-over type vehicle, and in particular, to a door window opening/closing device for a front door of a cab-over type vehicle. 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 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. be.

In Moeya's double-sliding window, the front and rear window glasses 70 and 71 open and close by sliding in the front-back direction, so there is no need to provide a window glass storage inside the door D, and therefore the height H of the window opening 72 is reduced. However, 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. As a result, the window opening 72 is constrained to have a rectangular 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.
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 one window opening U76 is increased as shown in FIG. Even if the height of the window opening 76 is lowered, the upper edge of the window glass 75 will protrude beyond the waist line 77, and in this case, increasing the height of the window opening 76 is meaningless. As mentioned above, if the waistline 77 is set upward due to the presence of the wheel arches 74, the side visibility from the driver's seat will be narrowed, and it will also be difficult to apply medication to the waistline while driving. Not only that, but when backing up a car, there was a problem in that the driver was unable to stick his or her upper body out of the window opening, making it difficult to check behind the vehicle, which could lead to an accident.

(Object of the Invention) The present invention was made to solve the problems of the conventional art, and its purpose is to provide a sliding window in which the angle of inclination of the windshield glass cannot be taken out of the sky, and a wheel arch part. In contrast to elevating windows where the height of the window opening cannot be adjusted to a large extent due to the presence of windshields, the present invention has a large tilt angle for the windshield glass, making it light and lightweight, while allowing for a large window opening height. To provide a door window opening/closing device for a front door of a cab-over type vehicle, which allows a line to be lowered.

(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 freely openable and closable.
