  However, in the above-described technique, when it is required to secure a wide opening area of the outside air intake from the viewpoint of satisfying the air conditioning capability, for example, as shown in FIG. When the cowl louver 110 is composed of panel surfaces (for example, the vertical wall surface 116 and the horizontal wall surface 118 shown in FIG. 7), and the outside air intake ports 116a and 118a are formed on both the panel surfaces 116 and 118, respectively, Since it is necessary to attach the mesh bodies 120, 120 individually to the edges of both the outside air intakes 116a, 118a, there has been a problem that it takes time to attach them. In order to solve this problem, one large net corresponding to the size of these two nets is arranged along a substantially L-shaped bent portion, and the folded net is connected to both outside air intakes. It was also considered to be attached to the edge of. However, in this idea, for example, when the net body is a resin net, an elastic force acts on the net body as it is bent, so that the workability of the attachment is deteriorated, and as a result, the labor required for the attachment is improved. I couldn't.

  The present invention is intended to solve such problems, and an object of the present invention is to provide a method for attaching a resin net to a cowl louver without requiring labor.

The present invention is for achieving the above object, and is configured as follows.
The invention according to claim 1 is a method of attaching a resin net to a cowl louver having at least two panel surfaces connected by a bent portion, and having both outside air inlets formed on both panel surfaces, The resin net is formed with a cut group formed by connecting the cuts in a dotted line in a fashioned manner along the bent portion so as to penetrate the thickness direction , and at least the cuts are located at both ends of the cut group. And a resin net is attached to both panel surfaces so as to cover the outside air intake port in a state where the cut group is bent along the bent portion.
According to this method, since the resin net can be held in a bent state along the notch, the elastic force does not act on the resin net along with the bending as described in the prior art. Thereby, deterioration of workability | operativity of attachment can be prevented and the effort which attachment requires can be improved as a result.

  First, a schematic configuration of the cowl louver 10 according to the first embodiment of the present invention will be described. As shown in FIG. 1, the cowl louver 10 has a recessed portion composed of an inclined surface 12, a bottom surface 14, and a vertical wall surface 16 so that the longitudinal section thereof is substantially U-shaped, and rearward from the vertical wall surface 16 of the recessed portion. This is a cover member that is formed of a lateral wall surface 18 that extends toward the vehicle and extends in the vehicle width direction.

  As is clear from FIG. 1, the horizontal wall surface 18 is formed to bend in a substantially L shape (by the bent portion 10a) with respect to the vertical wall surface 16. This description corresponds to “at least two panel surfaces connected by a bent portion” described in the claims.

  A rectangular outside air inlet 16a is formed in the vertical wall surface 16 along the longitudinal direction (in this case, the vehicle width direction). Further, similarly to the vertical wall surface 16, the lateral wall surface 18 is also formed with a rectangular outside air inlet 18a along the longitudinal direction (in this case, the vehicle width direction). Note that the cowl louver 10 including the inclined surface 12, the bottom surface 14, the vertical wall surface 16, and the horizontal wall surface 18 is integrally formed of, for example, a synthetic resin having rigidity.

  On the inner surfaces of the vertical wall surface 16 and the horizontal wall surface 18, a rectangular resin net (for example, a resin net of 16 mesh / inch with a wire diameter of φ0.3 is provided so as to cover the outside air intake ports 16 a and 18 a. ) 20 is attached (e.g., attached by welding). Here, the resin net 20 will be described in detail with reference to FIG. 2. The resin net 20 is formed with a dotted line-shaped cut 22 penetrating in the thickness direction (in FIG. 2, the thick line is notched). Is shown).

  As described above, when the resin net 20 is welded to the inner surfaces of the vertical wall surface 16 and the horizontal wall surface 18, the notch 22 is shaped along the bent portion 10 a that connects the vertical wall surface 16 and the horizontal wall surface 18. Is formed. The notch 22 is formed so that both ends thereof are notched.

  The resin net 20 is attached to the inner surfaces of the vertical wall surface 16 and the horizontal wall surface 18 so as to cover both the outside air intake ports 16a and 18a in a state where the notch 22 is bent along the bent portion 10a. The cowl louver 10 is configured in this way. In the first embodiment, since the cowl louver 10 is formed along the vehicle width direction, the notch 22 is also formed along the longitudinal direction of the resin net 20.
