The cowl louver 18 is connected to the molding 14 of the windshield with a molding 10. In this way, the connecting structure for a cowl louver and a windshield with a molding 20 is configured as shown in
(19) The windshield 12 is a windscreen, which is to be mounted to a front-side window frame of the vehicle body (not shown) and is made of laminated glass. Specifically, the windshield 12 is configured by bonding two glass plates (first glass plate and second glass plate) 22 and 24 via an Interlayer 26 made of PVB, EVA or the like as shown in
(20) As shown in
(21) As shown in
(22) The first molding portion 30 has an upper surface 30A bonded to an inner side surface 24A of the glass plate 24 by the double sided tape 16 at the lower edge portion 12A of the windshield 12. Although the first molding portion 30 is shown to be formed in a rectangular shape in longitudinal section, the first molding portion 30 may be formed in a shape other than a rectangular shape. The upper surface 30A of the first molding portion 30 may be bonded to the inner side surface 24A of the glass plate 24 by a known adhesive, such as an acrylic resin-based adhesive, a urethane resin-based adhesive or an epoxy resin-based adhesive.
(23) The second molding portion 32 is configured to extend upward from the first molding portion 30 along an end surface 12B of the lower edge portion 12A of the windshield. The end surface 12B means lower end surfaces of the glass plates 22, 24 and the interlayer 26. The second molding portion 32 is preferred to be apart from the end surface 12B by a gap (which means that the second molding portion 32 is not brought into contact with the end surface 12B). In a case where the second molding portion 32 is brought into contact with the end surface 12B, when there are variations in the external dimensions of the glass plates 22, 24, the assembling position of the molding 14 to the windshield varies. When the assembling position of the molding 14 to the windshield varies, the connection between the molding 14 and the cowl louver 18 could not be made at a desired position. To the contrary, in a case where there is a gap between the second molding portion 32 and the end surface 12B, even when there are variations in the external dimensions of the glass plates 22, 24, the presence of the gap between the second molding portion 32 and the end surface 12B can absorb variations in the external dimensions of the glass plates 22, 24. When the gap between the second molding portion 32 and the end surface 12B is at least 1.0 mm and at most 3.0 mm, it is possible to absorb variations in the external dimensions of the glass plates 22, 24.
(24) The third molding portion 34 has an upper surface 34A configured to extend from the second molding portion 32 in substantially parallel with an imaginary extension 22B of an outer side surface 22A of the glass plate 22, in other words, extend toward a front direction of the vehicle body, the imaginary extension being indicated by a double-dashed line. The third molding portion 34 is formed in a rectangular shape in longitudinal section so as to be engageable with the rear end portion 18A of the cowl louver 18, which is formed in a U-shape in section. Further, the upper surface 34A of the third molding portion 34 is disposed at a lower position than the imaginary extension 22B of the outer side surface 22A of the glass plate 22.

In other words, the third molding portion 34 and the rear end portion 18A are formed in a simpler shape than those of the connecting structure disclosed in Patent Document 2.
(37) In the connecting structure disclosed in Patent Document 2, it is difficult to produce the rib of the cowl louver and the snap-in recess of the molding with good accuracy since the rib and snap-in recess are formed in an extremely complicated shape. This makes it difficult in many cases to connect the cowl louver to the molding with good accuracy with respect to the connecting structure disclosed by Patent Document 2, being affected by the production accuracy of the rib and the snap-in recess.
(38) In contrast, in the connecting structure according to the first embodiment, fine adjustment can be easily made to the connection position of the cowl louver 18 to the molding 14 since the connection can be carried out by merely fitting the third molding portion 34 in a rectangular shape in longitudinal section into the rear end portion 18A in a U-shape in longitudinal section. By this arrangement, it is possible to connect the cowl louver 18 to the molding 14 with good accuracy without being affected by the production accuracy for each of the third molding portion 34 and the rear end portion 18A. Thus, the connecting structure 20 for a cowl louver and a windshield with a molding according to the first embodiment, it is possible to solve the problem of the production accuracy for each of the molding and the cowl louver, which is involved in the connecting structure according to Patent Document 2.
(39) As described above, In accordance with the windshield with a molding 10 of the first embodiment, it is possible to simultaneously solve the problems of abnormal noise and glass breakage caused by a foreign matter, and the problem of workability in connection of a cowl louver 18 to the windshield 12.
