DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cowl louver disposed in a vehicle width direction between a windshield and a hood covering an upper part of an engine room, on the upper surface side of the cowl provided below the windshield.

[0002]

2. Description of the Related Art Conventionally, a cowl louver of this type has been disclosed in, for example, Japanese Utility Model Publication No. 4-10091, in which the workability at the time of assembling the vehicle body is improved, and the mold removability at the time of manufacturing with a synthetic resin is improved. Divide the louver divided part from the middle part in the width direction of the vehicle into two louver divided pieces for the purpose of improving the condition, and assemble them together with the divided end faces of the louver divided parts facing each other and attach them to the upper side of the louver. ing.

[0003]

However, according to the above-described cowl louvers, when the louver divided pieces are assembled in a butt shape, these louver divided pieces are formed of thin plate-shaped members. It is difficult to accurately abut the end faces of the pieces and the workability is poor. In addition, since the butted end faces of the louver divided pieces made of a thin plate-like member are in a line contact state, the rigidity of the butted end face portions is weak. Become.

[0004] It is an object of the present invention to improve the operability by easily and accurately abutting the end faces of the louver divided pieces, despite the formation of the cowl louver, and to improve the workability. The point is that the rigidity of the end face portion can be enhanced.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, the louver divided pieces 5 and 6 divided at the intermediate portion in the vehicle width direction are integrally assembled in a butt shape to form a cowl. 2 is a cowl louver that covers the upper surface of the louver 2, wherein each of the louver split pieces 5, 6 has a concave groove 56, 6 extending in the vehicle width direction.
6, the openings of the concave grooves 56, 66 are closed at the abutting portions of the rain guide portions 52, 62 in the louver divided pieces 5, 6, respectively.
In addition, vertical walls 57 and 67 are provided so as to face each other when the louver divided pieces 5 and 6 abut against each other.

[0006]

According to the first aspect of the present invention,
Rain guide parts 52, 6 provided on each louver divided piece 5, 6
Since the vertical walls 57 and 67 are provided on the opening side of the concave grooves 56 and 66 formed in the rain guide portions 52 and 62 at the abutting portion 2, the louver divided pieces 5 and 6 are abutted and assembled integrally. By attaching the vertical walls 57 and 67 to each other, the louver divided pieces 5 and 6 can be easily and accurately assembled in a butt shape to improve workability. By forming the concave grooves 56 and 66 in the 52 and 62 and providing the vertical walls 57 and 67 on the opening side, the rigidity of the butted portions of the louver divided pieces 5 and 6 can be increased. Further, the respective rain guide portions 52, 6
By forming the vertical walls 57, 67, which are closed at the abutting portions of the grooves 2 and 66 at the opening sides of the grooves 56, 66 and face each other in a face-to-face manner during assembly, the grooves 56, 66 are formed.
It is also possible to prevent rainwater and the like flowing into the water from leaking downward from the abutting portion on the opening side thereof, and also to drain the rainwater and the like through the concave grooves 56 and 66 in a laterally distributed manner.
