  As shown in FIG. 2, in this embodiment, the cowl top panel 10 includes a cowl top front 11 disposed on the front hood 2 side (the vehicle front side), a cowl top inner 12 disposed on the rear side, and a cowl. A cowl top upper 13 disposed on the top of the top inner 12 is formed in a hollow shape. A predetermined gap is secured between the cowl top front 11 and the cowl top upper 13, and the cowl top panel 10 forms an open cross section with the upper side opened in the vehicle width direction. Further, the cowl top upper 13 is disposed below the lower end portion of the windshield glass 1 and supports the windshield glass 1. In addition, although illustration is abbreviate | omitted in the space 14 formed with this cowl top panel 10, a wiper unit etc. are arrange | positioned, for example.

  The deck garnish 20 is fixed to the cowl top panel 10 so as to close the space 14 formed by the cowl top panel 10, that is, close the gap between the cowl top front 11 and the cowl top upper 13. The deck garnish 20 is provided with, for example, a vent hole 20a for taking outside air into an air intake duct of an air conditioner (see FIG. 2). The deck garnish 20 has a rear end (vehicle rear side end) attached to the lower end of the windshield glass 1. The front end (vehicle front side end) of the deck garnish 20 is fixed to the cowl top panel 10 (the cowl top front 11) by a plurality of fixing portions 30 arranged at predetermined intervals in the vehicle width direction (FIG. 1). reference).

  Hereinafter, the structure of the main part of the deck garnish 20 and the cowl top panel 10 of this embodiment and the fixing | fixed part 30 which fixes these is demonstrated in detail.

  As shown in FIGS. 3 and 4, the cowl top front 11 constituting the cowl top panel 10 includes a cowl top wall surface portion 15 erected in the vertical direction, and an upper end portion of the cowl top wall surface portion 15 toward the vehicle front side. An extended cowl top flange portion 16 (a front end portion of the cowl top panel 10). In this embodiment, the cowl top wall 15 is inclined at a predetermined angle so as to be inclined downward from the front to the rear of the vehicle. In each fixing portion 30, the cowl top wall surface portion 15 is provided with an engagement hole 17 in which a locking claw 26 of a deck garnish 20 described later is engaged. That is, the engagement holes 17 are provided in the cowl top wall portion 15 at a predetermined interval in the vehicle width direction. In the present embodiment, the cowl top flange portion 16 extends from the upper end portion of the cowl top wall surface portion 15 toward the vehicle front side in a substantially horizontal direction.

  On the other hand, the deck garnish 20 includes a deck garnish wall surface portion 21 erected in the vertical direction, and a plurality of deck garnishes that extend from the lower end portion of the deck garnish wall surface portion 21 to the vehicle front side and abut against the cowl top flange portion 16. And a flange portion 22 (a front end portion of the deck garnish 20). The deck garnish wall surface portion 21 is provided so as to be inclined so that the angle θ with respect to the deck garnish flange portion 22 is an acute angle. In the present embodiment, the deck garnish wall surface portion 21 is provided in parallel to the cowl top wall surface portion 15.

  Similarly to the cowl top flange portion 16, the deck garnish flange portion 22 extends from the deck garnish wall surface portion 21 toward the vehicle front side in a substantially horizontal direction. A locking portion 23 that protrudes downward from the deck garnish flange portion 22 and is locked to the leading end portion of the cowl top flange portion 16 is provided at the distal end portion of the deck garnish flange portion 22. That is, when the locking portion 23 is locked to the cowl top flange portion 16, the movement of the deck garnish 20 toward the vehicle rear side is restricted.

  A plurality of ribs 24 are provided at predetermined intervals in the vehicle width direction inside the locking portion 23. Actually, the tip end portion of the cowl top flange portion 16 comes into contact with the plurality of ribs 24. These ribs 24 are provided for final adjustment (tuning) when a dimensional error occurs between the cowl top flange portion 16 and the deck garnish flange portion 22, for example. When such a dimensional error occurs, it is necessary to adjust the size of the locking portion 23 by processing a mold for forming the deck garnish 20. At this time, if the rib 24 is provided, only the portion corresponding to the rib 24 of the mold needs to be processed, and the adjustment work can be performed relatively easily. Of course, these ribs 24 are not essential components, and may be provided as necessary.

  In each fixing portion 30, the deck garnish flange portion 22 is provided with an engaging projection 25 that extends downward from the lower surface along the surface of the cowl top wall portion 15. A locking claw 26 that protrudes toward the cowl top wall surface 15 and engages with the engagement hole 17 is provided at the distal end of the engagement protrusion 25. That is, a plurality of engaging protrusions 25 and locking claws 26 are provided corresponding to the plurality of engaging holes 17 of the cowl top wall surface portion 15. Further, the engaging protrusion 25 substantially contacts the surface of the cowl top wall surface portion 15 in a state where the locking portion 23 is locked to the tip end portion of the cowl top flange portion 16, and The cowl top flange portion 16 is sandwiched between the two.

  When the front end portion of the deck garnish 20 having such a configuration is attached to the cowl top panel 10, the deck garnish flange portion 22 is locked to the tip end portion of the cowl top flange portion 16 while the deck garnish flange portion 22 is locked. The portion 22 is brought into contact with the cowl top flange portion 16. At this time, in each fixing portion 30, the engaging protrusion 25 including the locking claw 26 slides on the surface of the cowl top wall surface portion 15 while being bent rearward, and each locking claw 26 moves to the cowl top wall surface. It engages with an engagement hole 17 formed in the portion 15.

  Thereby, the front-end part of the deck garnish 20 and the cowl top panel 10 can be fixed favorably. Moreover, the space saving of the front deck part 3 can be achieved by making each fixing | fixed part 30 the above structures. Specifically, the width (width in the front-rear direction of the vehicle) W1 of the cowl top flange portion 16 can be reduced. Accordingly, the width of the deck garnish flange portion 22 can be reduced.

  For example, in the conventional structure in which the front end of the cowl top and the front end of the deck garnish are fixed with a clip or the like, it is necessary to form mounting holes for mounting the clips on the cowl top flange portion and the deck garnish flange portion 22. For this reason, it is necessary to ensure the width of the cowl top flange portion and the deck garnish flange portion relatively wide. Furthermore, it is necessary to ensure the width of the cowl top flange portion and the deck garnish flange portion relatively wide from the viewpoint of securing a space for mounting the clip. In particular, as in the above-described embodiment, when the angle of the deck garnish wall surface portion 21 with respect to the deck garnish flange portion 22 is provided at an acute angle, the insertion locus of the clip or the like and the deck garnish wall surface portion 21 interfere with each other. In order to ensure a sufficient clearance, the width of the cowl top flange or the like in the vehicle front-rear direction needs to be wider. For this reason, it is difficult to make the cowl top flange part small, and the front deck part 3 has been enlarged.

  In the configuration of the present invention, such a problem can be solved and space saving of the front deck portion 3 can be achieved. In each fixing portion 30, a through hole 27 is formed at a position corresponding to the engagement protrusion 25 of the deck garnish flange portion 22. The through hole 27 is formed by a mold (pin) for forming the engaging projection 25 including the locking claw 26 at the time of deck garnish molding. The size is significantly smaller than the seating surface width required for the mounting hole for mounting a clip or the like. In addition, this through-hole 27 is not an indispensable structure, and should just be provided as needed.

  Further, in the configuration of the present embodiment, parts such as a clip are not necessary, and the attachment of the deck garnish 20 to the cowl top panel 10 is facilitated and the working efficiency is improved, so that the manufacturing cost can be reduced.

  Furthermore, the attachment structure of the tip garnish 20 and the cowl top panel 10 as described above improves the effect as an impact absorbing portion that absorbs the impact force when a pedestrian or the like collides with the automobile, for example. I can also expect that. That is, when a large impact is applied to the deck garnish 20 when a pedestrian or the like collides, the locking portion 23 of the deck garnish flange portion 22 is detached from the cowl top panel 10 and falls to the rear of the cowl top wall portion 15. Will deform more greatly. This deformation absorbs the impact and can also be expected to reduce the impact received by the pedestrian.

  In the present embodiment, the deck garnish 20 is provided with draining ribs 28 extending from the deck garnish wall surface portion 21 to below the deck garnish flange portion 22 (see FIG. 4). The draining rib 28 is preferably extended to the lower side of the engagement hole 17, specifically, to the lower side of the extension line L <b> 1 at the lower end of the engagement hole 17. By providing such a draining rib 28, rainwater flowing along the cowl top wall portion 15 is prevented from entering the engine room from the contact surface between the cowl top flange portion 16 and the deck garnish flange portion 22. can do. Furthermore, since the draining rib 28 extends to the lower side of the engagement hole 17, the intrusion of rainwater from the engagement hole 17 in the engine room can be effectively suppressed.

  As mentioned above, although one Embodiment of this invention was described, of course, this invention is not limited to the above-mentioned embodiment, In the range which does not deviate from the meaning, it can change suitably.
