A plurality of base portions 12 of the hook portion 11 shaped along the main body 7 are provided apart from each other in the vehicle width direction together with the abutting portion 13. In order to reduce the gap between the abutting portion 13 and the main body 7, the base portion 12 is combined. During molding of the main body 7 using a resin material, it is necessary to use a split slide mold as a core that secures a space between the hook portion 11 and the main body portion 7.
The sliding direction of the mold is an arrow direction (vehicle longitudinal direction) indicated by a dotted line in FIG. 7 and a direction (vehicle width direction) orthogonal to this direction. Considering the limited gap between them, the split mold becomes complicated, and it is difficult to align with the mold body, which causes burrs.

  In particular, as shown in FIG. 7, the direction of the lip portion 5 during molding and the direction of the top surface 14 are convergent to each other, that is, undercut, so when the mold is slid Even if the elasticity of the lip portion 5 is utilized, there is a limit, which complicates the slide mold and causes burrs.

  Further, when the cowl louver device 4 is attached, since the frame number cover portion 10 is a separate body, the frame number cover portion 10 is attached to the main body 7 and the opening operation of the main body 7 is closed. In addition, it complicates parts management.

  Therefore, this invention makes it the subject which should be solved to eliminate the malfunction of a prior art.

  In order to solve the above-described problems, the present invention allows the lip portion of the cowl louver body and the top surface and the lip of the abutting portion of the hook portion to be spaced substantially parallel to each other so that the mold can be slid horizontally. Use technical means. A lip is provided at the abutment portion of the abutment portion 13 with respect to the windshield to avoid point contact with the windshield.

  The frame number cover part is molded integrally with the cowl louver body or rain catch cover part. At the time of molding, the frame number cover part is tilted forward in front of the opening of the cowl louver body and restored to the front when the opening is closed. The opening is closed by force.

  Preferably, one end of the frame number cover part is coupled to the cowl louver main body or the rain receiving cover part from both sides via an R-grooved part.

  According to the present invention, there is provided a cowl louver device for an automobile that is located between a windshield and a hood and has at least a cowl louver body, and the cowl louver body supports a lip portion and a windshield that can contact the windshield at a rear edge thereof. A hook portion formed integrally with the cowl louver main body and provided with a plurality of base portions spaced apart in the vehicle width direction, and a contact portion extending above the base portion, In the mounted state, the lip portion and the top surface of the abutting portion are in a substantially parallel relationship or a relationship in which the distance increases toward the rear of the vehicle, and a lip is formed along the top surface of the abutting portion. An automobile cowl louver device is provided in which a contact portion supports a windshield.

  The lip portion of the cowl louver main body and the top surface of the abutment portion and the lip are substantially parallel, or the distance increases toward the rear of the vehicle, there is no undercut, and the sliding direction is in the horizontal direction along the top surface. Therefore, the structure of the mold can be simplified and the occurrence of burrs can be prevented.

  Since the lip portion and the lip are elastically deformed and are in close contact with the windshield, the sealing performance is high, and the lip portion and the lip are not subjected to a large elastic deformation at the time of die cutting at the time of molding.

  Forming the frame number cover part integrally with the cowl louver body or rain receiving cover part changes the position of the frame number cover part at the time of molding and the position when the opening of the cowl louver body is closed. The opening can be firmly closed by the restoring force to the position. The opening operation may be performed by elastically deforming a part of the frame number cover part and releasing the engagement between them.

  This configuration simplifies the assembling work, and makes it easy to reduce the number of parts and manage parts.

An automobile cowl louver device 21 according to a preferred embodiment of the present invention has a cowl louver main body, that is, a main body 22, and a rear end portion of the main body 22 is formed to be separated from each other in the vehicle width direction as shown in FIG. 2. It has a hook portion 23 and a lip portion 24 extending in the vehicle width direction. 1 and 2, only one hook portion 23 is shown.
With reference to FIG. 2 and FIG. 3, the structure of the hook part 23 is shown. The hook portion 23 has a base portion 25 that is integral with the main body 22 and a contact portion 26 that extends upward from the rear end of the base portion 25. The top surface 27 of the contact portion 26 is a horizontal plane and is formed substantially parallel to the lip portion 24.

At the front end of the abutting portion 26, a tongue piece or lip 29 extends forward along the top surface 27 via an R-shaped groove 28. The size of the lip 29 is appropriately selected.
Since spaces are formed between the main body 22 and the hook portion 23 and between the lip portion 24 and the contact portion 26, when the main body 22 is molded with synthetic resin, these spaces are secured using a core or the like. There is a need.

  According to the present invention, the top surface 27 and the lip 29 and the lip portion 24 are formed substantially parallel to each other, or the distance between the top surface 27 and the lip portion 24 is increased toward the rear of the vehicle. 3 can be defined as a horizontal direction indicated by a dotted line in FIG. 3 and a direction perpendicular to the horizontal direction (vehicle width direction), and there is no oblique sliding direction as in the prior art. Design can be facilitated and the cost of the mold can be reduced.

  The lip portion 24 extends through the R-grooved groove 30, and when the lip portion 24 contacts the windshield 3, the lip portion 24 is elastically deformed with the groove 30 as a center to enhance the close contact with the windshield 3.

The cowl louver device 21 further includes a rain receiving cover portion 31 and a frame number cover portion 32. The rain receiving cover portion 31 extends along the vehicle body and has an opening 34 facing the opening 33 of the main body 22. The front edge 35 of the rain receiving cover portion 31 is locked to the lower end of the opening 33 of the main body 22.
