A more detailed structure will be described based on cross-sectional views of the respective parts.
FIG. 5 is a cross-sectional view taken along line 5-5 of FIG. 4, and a cowl box 34 disposed along the lower edge of the windshield 11 for introducing outside air into the vehicle interior, and the upper surface of the cowl box 34 are covered. And a cowl top garnish 16 having a vent hole 22... With the upper garnish 13 whose front edge 35 abuts on the cowl top garnish 16. It is characterized by wearing a cowl top garnish 16 including it.

17 is a clip for attaching the front edge 35 of the upper garnish 13 to the cowl top garnish 16, and 36 is a clip for attaching the rear part of the cowl top garnish 16 to the box top plate 37.
Reference numeral 38 denotes a sealing material extended from the cowl top garnish 16 in order to maintain the sealing performance with the hood 12. Reference numeral 39 denotes a space between the front wall lower flange 40 of the cowl top garnish 16 and the front wall upper flange 41 of the cowl box 34. It is a sealing material interposed between the two.

As shown by arrows A and B, outside air can be introduced into the cowl box 34 through the air holes 22.
When rainwater is introduced together with the outside air, it can be accumulated at the bottom of the cowl box 34 and moved to the front and back of the drawing to be discharged.

  By the way, when the sealing performance of the sealing material 38 is lowered, there is a risk that hot air leaks from the engine room. Even in that case, the leaked hot air flows on the upper garnish 13 as indicated by an arrow C. That is, since the air holes 22... Are under the upper garnish 13, there is no fear that hot air enters the air holes 22. Therefore, fresh outside air can be introduced into the cowl box 34 through the vent holes 22.

  In addition, since the ventilation holes 22 are covered with the upper garnish 13, the ventilation holes 22 are not visible from the outside, and the appearance can be improved.

  Furthermore, since the upper garnish 13 is attached not to the hood 12 but to the cowl top garnish 16, it can be easily brought close to the windshield 11 or the like.

  6 is a cross-sectional view taken along line 6-6 in FIG. 4. The rib 46 is extended from the lower surface of the upper garnish 13, and the lower end of the rib 46 is brought into contact with the cowl top garnish 16. FIG. The rib 46 can increase the rigidity of the upper garnish 13, and the rib 46 can maintain a constant distance between the upper garnish 13 and the cowl top garnish 16, thereby ensuring an air passage below the upper garnish 13. Can do.

The rib 46 may be integrally formed with the upper garnish 13.
However, in the present invention, the rib 46 is a separate part from the upper garnish 13, and both are integrated with a screw 50 as a connecting means.
By forming the rib 46 as a separate part, molding becomes easy. That is, the upper garnish 13 can be easily molded, the molding die is simplified, and the molding cost can be reduced.

  It should be noted that rainwater that has entered the lower part of the cowl top garnish 16 accumulates on the box top plate 37 that forms the upper surface of the cowl box 34 having a substantially U or U-shaped cross section. The accumulated water moves in the direction of the front and back of the drawing and falls to the cowl box 34, but remains on the box top plate 37 until then. A sealing material 47 is interposed between the front edge of the box top plate 37 and the front edge of the cowl top garnish 16 so that the accumulated water does not leak.

However, there is a possibility that the sealing effect of the sealing material 47 is weakened due to various factors such as vibration and aging deterioration, and the accumulated water leaks and falls into the engine room 48. As a countermeasure, in the present invention, the flange member 19 is suspended from the front edge of the cowl top garnish 16 using a pin 49.
The eaves member 19 has a substantially U-shaped cross section. That is, the gutter member 19 includes a hang part 51, a wall part 52 depending from the hang part 51, and a floor part 53 extending from the lower end of the wall part 52. The floor portion 53 extends substantially in parallel to the joint portion 56 that inclines forward and descends toward the rear of the vehicle body. As a result, water is collected in the valley portion 54 and flows in the direction of the front and back of the drawing.

  When the lower wall 40a is lowered from the front edge of the front wall lower flange 40 of the cowl top garnish 16, water may be sucked up by capillary action if the wall 52 and the lower wall 40a are brought close to each other. Therefore, the gap t between the two is determined to be 1 to 3 mm, preferably 2 mm. Thereby, the phenomenon of sucking up water can be prevented.

The pin 49 will be described in detail.
If the cowl top garnish 16 is made of a thermoplastic resin, the pins 49 can be integrally molded simultaneously during injection molding. The hang part 51 is passed through the projecting pin 49, and the head of the pin 49 projecting from the hang part 51 is melted and crushed by a heat caulking jig such as a soldering iron, and flattened. This eliminates the worry that the hang part 51 comes off from the pin 49.

  The pin 49 is made of a relatively soft metal, the metal pin is planted in the cowl top garnish 19, the hang portion 51 is passed through the protruding pin 49, and the head of the pin 49 protruding from the hang portion 51 is mechanically caulked. Crush and flatten with a jig. This eliminates the worry that the hang part 51 comes off from the pin 49.

In either the heat caulking or the mechanical caulking, the head of the pin 49 is crushed, so that the protrusion of the pin 49 is eliminated and the mounting structure of the flange member 19 can be made compact. Therefore, the collar member 19 can be attached in a narrow space. In addition, if caulking is used, a mounting seat such as other fixing means is not required, and the size can be reduced.
Further, the coupling means described for the pins 49 may be clips, bolts, or screws in addition to resin pins and metal pins. Furthermore, an adhesive may be used.

  FIG. 7 is a view taken in the direction of arrow 7 in FIG. 6 and shows that the eaves member 19 is suspended from the lower portion 40 of the front wall of the cowl top garnish 16. Since the horizontal direction in the drawing corresponds to the vehicle width direction, the flange member 19 extends in the vehicle width direction.

  FIG. 8 is a sectional view and action diagram of the eaves member according to the present invention. The front wall lower flange 40 of the cowl top garnish 16 and the front edge of the box top plate 37 are aligned, and a sealing material 47 is interposed therebetween. A flange member 19 that receives water leaked from the joint portion 56 is provided at a position above the electrical component 18 in the joint portion 56 and at a position where the joint portion 56 wraps in the longitudinal direction of the vehicle body. No. 16 is characterized in that the floor portion 53 thereof is inclined in the vehicle width direction and the lowermost end of the floor portion 53 is extended to a position where it does not overlap the electrical component 18 in the vehicle width direction.

And the floor 53 of the gutter member 19 is inclined in the vehicle width direction. The inclination angle is preferably 3 ° to 20 °, and more preferably 13 ° to 16 °.
Further, the standing wall 58 is preferably set up at the starting point of the slope to prevent water leakage in the right direction in the figure, and the hanging wall 59 is suspended from the lowermost end, which is the end point of the slope. Was prevented from wrapping around.

  By attaching the gutter member 19, the water 60 leaking through the joint 56 can be moved in the vehicle width direction like water 61 and water 62 and dropped to a place where it does not overlap with the electrical component 18. Can be protected from water wetting.

By the way, if the electrical component 18 is simply protected, there is a method of covering the electrical component 18 side with a protective cover. In this case, when the electrical component 18 is inspected, the protective cover must be removed each time, and the attachment may be forgotten after the inspection.
In this regard, according to the present invention, there is no hindrance to the inspection of the electrical component 18, and no forgetting to attach it occurs.
In addition, since the eaves member 19 is a part with a very simple shape, it can be manufactured at a low cost and exhibits an effect that the protective cover does not have.

  The cowl structure of the present invention is suitable for a passenger car, but may be applied to other types of vehicles such as trucks and jeeps.

  The present invention is suitable for a cowl structure at the front of a passenger car.
