The bottom wall portion 5e extends, the front wall portion 5f extends upward from the front edge of the bottom wall portion 5e, and the flange portion 5g extends forward from the upper edge of the front wall portion 5f.

  The upper wall portion 5c extends so as to cover the lower edge portion 3a of the windshield 3, and the rear edge portion 5c 'of the upper wall portion 5c is connected to the rear edge portion 5c' of the windshield 3. A grip portion 5h that grips the lower edge portion 3a is formed at a predetermined interval in the vehicle width direction (see FIG. 3). The upper wall portion 5c and the vertical wall portion 5d are formed with an outside air inlet 5j for introducing traveling wind into the passenger compartment B.

  The vertical wall portion 5d, the bottom wall portion 5e, and the front wall portion 5f form a drainage groove 5i that discharges rainwater and washing water that has entered between the hood 2 and the cowl louver 5 to the outside of the vehicle.

  Further, a seal member 7 is mounted on the flange portion 5g so as to seal the space between the hood 2 and the cowl louver 5 while being pressed against the hood 2.

  A plurality of mounting flange portions 5k are formed on the left and right ends of the cowl body 5a in the vehicle width direction. The left and right mounting flanges 5k are fastened and fixed to the above-described cowl side member.

  The bottom wall portion 5e of the cowl body 5a is fixed to the front flange 1c of the inner panel 1a via an ept sealer 8.

  Four mounting seats 5b are formed in the bottom wall portion 5e of the cowl body 5a with a predetermined interval in the vehicle width direction. Each mounting seat 5b is attached to the front flange 1c of the cowl panel 1 via a clip 10, and has the following structure in detail.

  The clip 10 is engaged with the mounting seat 5b to sandwich the mounting seat 5b, and a clip body 10b that is elastically modified and inserted into and fixed to a mounting hole 1d formed in the front flange 1c. Have

  Each of the mounting seats 5b is formed on the front flange 1c of the cowl panel 1 following the clip mounting hole 5m formed so as to open toward the side in the vehicle width direction and the bottom wall portion 5e of the cowl body 5a. It has a support wall 5n protruding downward so as to face each other and integrally connected to each outer edge portion excluding the clip mounting hole 5m of the mounting seat 5b.

  Among the mounting seats 5b, the clip mounting holes 5m of the left and right mounting seats 5b located on the outer side in the vehicle width direction open inward, and the left and right mounting seats 5b located on the inner side. The clip mounting hole 5m opens outward (see FIG. 2).

  The clip mounting hole 5m is expanded so as to form a circular insertion hole 5p to which the clip 10 is mounted and fixed, and the insertion hole 5p is formed in a generally V shape in the opening direction, and the clip 10 is inserted into the insertion hole 5p. And a guide groove 5q for guiding.

  Each mounting seat 5b is divided into a front side part (one side part) 5r and a rear side part (other side part) 5s by a clip mounting hole 5m, and the divided front side part 5r and rear side part 5s are divided. Is set to a value with different strength against external force.

  In the present embodiment, the strength of the front side portion 5r is smaller than the strength of the rear side portion 5s. Specifically, the strength difference is set by the following structure.

  The support wall 5n of the front side portion 5r of each mounting seat 5b has an opening 5t formed by cutting out most of this. As a result, in the front side portion 5r, the opening end portion of the guide groove 5q is supported by the thin support wall 5n ′.

  Further, the clip mounting holes 5m of the respective mounting seats 5b are offset to the front side by P with respect to the center line b in the vehicle width direction in which the center line a of the mounting holes 5m passes through the center in the front-rear direction of the mounting seat 5b. Formed in position. Thereby, the front-rear direction dimension t1 of the front side part 5r is smaller than the front-rear direction dimension t2 of the rear side part 5s (see FIG. 8B). In this way, the strength of the front side portion 5r is made smaller than the strength of the rear side portion 5s.

  According to the present embodiment, each mounting seat 5b formed integrally with the cowl body 5a is notched and formed with a clip mounting hole 5m that opens laterally in the vehicle width direction, and is formed by the clip mounting hole 5m of the mounting seat 5b. Since the strength against the external force of the divided front side portion 5r and rear side portion 5s is set so that the front side portion 5r is smaller than the rear side portion 5s, when a collision load is applied to the cowl louver 5 due to the fall of the collision object, The front side portion 5r having a small strength of the mounting seat 5b is detached due to the breakage of the support wall 5n ′, and the impact force absorbing function can be enhanced.

  On the other hand, the rear side portion 5s is higher in strength than the front side portion 5r because it is surrounded by the support wall 5n. Therefore, for example, when a load is applied to the cowl louver 5 by hand pressing from above during car washing, the load is borne by the rear side portion 5s having high strength, and the cowl louver 5 can be prevented from being detached or deformed.

  In the present embodiment, the mounting seat 5b is integrally connected to the cowl body 5a by the support walls 5n and 5n 'formed so as to surround the clip mounting hole 5m. , Rigidity can be ensured.

  Further, since the clip mounting hole 5m of the mounting seat 5b is formed so as to open toward the side in the vehicle width direction, the cowl louver 5 can be prevented from coming off the clip 10 due to the load acting on the cowl louver 5. That is, when the clip mounting hole is opened in the front-rear direction, when a load is applied to the cowl louver 5 from above, the vertical wall portion 5d is elastically deformed in the front-rear direction along with the elastic deformation of the cowl body 5a in the vertical direction. There is a risk that the clip 10 may come off. In this embodiment, even if the vertical wall portion 5d is elastically deformed in the front-rear direction, the clip 10 does not come off.

  In the above embodiment, the strength of the front side portion 5r of the mounting seat 5b is made smaller than that of the rear side portion 5s, but the present invention may make the strength of the rear side portion smaller than that of the front side portion. Also in this case, the impact force absorbing function can be enhanced while ensuring the strength and rigidity of the mounting seat.
