ところで、前記従来の取付け構造では、カウルルーバのフロントガラスへの組み付け精度のばらつきにより、該カウルルーバの爪がカウルパネルの取付け孔の縁部に引っ掛かって挿入できない場合がある。特に、近年のフロントガラスは、曲率を大きくしたラウンド形状となっていることから、カウルルーバの挟持部のフロントガラスへの装着荷重が大きくなり、挟持部を奥まで押し込めない場合がある。その結果、カウルルーバ全体が前側にずれることから、爪が取付け孔の前縁部に引っ掛かることとなる。またフロントガラスに挟持部を奥まで装着した場合には、爪が取付け孔の後縁部に引っ掛かる場合があり、組付け時の作業性を高めるために、この点での改善が要請されている。   By the way, in the conventional mounting structure, there are cases where the claw of the cowl louver is caught on the edge of the mounting hole of the cowl panel and cannot be inserted due to variations in the assembly accuracy of the cowl louver on the windshield. In particular, since the windshield in recent years has a round shape with a large curvature, there is a case where the mounting load on the windshield of the clamping portion of the cowl louver increases and the clamping portion cannot be pushed all the way into the windshield. As a result, the entire cowl louver is displaced forward, so that the claw is caught on the front edge of the mounting hole. In addition, when the nipping part is attached to the windshield as far as it will go, the claw may be caught on the rear edge of the mounting hole, and this point is required to improve the workability during assembly. .

本発明は、前記従来の状況に鑑みてなされたもので、組み付け精度のばらつきが生じた場合にも確実に取り付けることができる車両用カウルルーバの取付け構造を提供することを課題としている。   The present invention has been made in view of the above-described conventional situation, and it is an object of the present invention to provide a vehicle cowl louver attachment structure that can be reliably attached even when variations in assembly accuracy occur.

And the non-woven fabric adhered to the sandwiching piece, and the gap between the non-woven fabric and the rear flange portion was set to a value that substantially matches the thickness of the windshield . For example, even if the windshield has a large round shape, the cowl louver clamping portion can be easily attached to the lower edge of the windshield, and the amount of attachment can be made uniform. Assembling accuracy can be increased.

さらにまた、後側挿入ガイド部を、基部の下端部後面を覆う円弧状をなすよう膨出形成したので、後側挿入ガイド部が取付け孔の後縁部に当たると、基部が前側に弾性変形して取付け孔内に誘導されることとなり、組み付け時の作業性を高めることができる。
 Furthermore, since the rear insertion guide portion is formed so as to form an arc shape covering the rear surface of the lower end portion of the base portion, when the rear insertion guide portion hits the rear edge portion of the mounting hole, the base portion is elastically deformed to the front side. Therefore, it is guided into the mounting hole, so that the workability at the time of assembly can be improved.
