Japanese Unexamined Patent Publication No. 2013-230711

In the structure of Reference 1 shown in FIG. 6, the lower end of the windshield glass 130 and the wiper rain gutter are used to facilitate the assembly of the cowl louver 110 on the vehicle to which the windshield glass 130 and the pivot shaft member 124 are fixed. A first interval D101 of a first predetermined distance or more is indispensable between the 112 and the 112. Further, in order to avoid interference between the front end portion 112S of the wiper rain gutter, which is the tip portion of the wiper rain gutter 112 on the front side of the vehicle, and the upper tip portion 126S of the wiper unit rain gutter 126 on the rear side of the vehicle, a second predetermined distance is provided. The above second interval D102 is also essential. Further, in order to avoid interference between the trailing edge tip 111S of the pivot hole, which is the tip of the rear edge of the pivot hole 111A, and the upper tip 126S of the wiper unit rain gutter 126, a third predetermined distance or more The third interval D103 of is also essential. Therefore, since the first interval D101, the second interval D102, and the third interval D103 in FIG. 6 are all indispensable, the distance from the rear edge portion of the louver main body 111 to the tip end portion 111S of the trailing edge of the pivot hole. The evaluation distance DZ is relatively long.

When the evaluation distance DZ shown in FIG. 6 becomes relatively long, as shown in FIG. 5, at the lower end of the windshield glass 130 on the driver's seat side (on the left side of the paper in the example of FIG. 5) where the pivot shaft member 124 is arranged. It becomes necessary to form the notch 130A. Note that FIG. 5 is a view of the windshield glass 130 when the conventional wiper peripheral structure shown in FIG. 6 is provided, as viewed from above. As shown in FIG. 5, a notch 130A is formed on the driver's seat side (the side on which the pivot shaft member 124 is arranged) of the windshield glass 130 with respect to the symmetrically shaped windshield glass indicated by reference numeral 130B. If this is the case, the windshield glass 130 will have a left-right asymmetrical shape.

In recent years, vehicles for various countries such as right-handed countries and left-handed countries have been produced at various factories, and vehicles for right-handed countries and vehicles for left-handed countries have been produced. At the factory, it is necessary to manage the windshield glass for the country with right-hand traffic and the windshield glass for the country with left-hand traffic, which have different asymmetrical shapes. It takes extra space. Of course, even a factory that manufactures windshield glass must manufacture windshield glass with different left-right asymmetric shapes, one for right-handed national windshield glass and the other for left-handed national windshield glass. It takes time and effort for production control and extra warehouse space. However, if the evaluation distance DZ shown in FIG. 6 can be shortened to less than a predetermined distance, the notch 130A shown in FIG. 5 becomes unnecessary, and the windshield glass 130 has a symmetrical shape as shown by the dotted line of reference numeral 130B. Is possible. If the windshield glass 130 can have a symmetrical shape, labor in production control and warehouse space can be saved, so that it is desired to shorten the evaluation distance DZ. Even if the evaluation distance DZ cannot be shortened until the windshield glass can be made symmetrical, if the evaluation distance DZ can be shortened, the driver's field of view can be widened downward and the cowl louver can be used.
