  As shown in FIG. 6, the extending portion 40 is positioned to face the mounting bracket 12, and the side portion of the mounting bracket 12 is covered by the flange portion 42 formed on the side portion of the extending portion 40. ing. Here, the flange portion 42 is inserted into the through hole 14 formed in the mounting bracket 12 and covers the inner surface of the through hole 14.

  Further, the blindfold 32 faces the mounting bracket 12 and also faces the front side of the protrusion 15. The ventilation portions 33 are located on both sides of the mounting bracket 12.

  Next, the operation of the front grille F will be described.

  When the vehicle 10 provided with the front grille F as described above travels, the cooling water flowing through the radiator R warms up, and the water temperature rises to a high temperature. At this time, air flows from a large number of ventilation openings 21 formed in the grill main body 20, hits the radiator R located inside the vehicle 10, and cools the radiator R.

  Here, since the grill body 20 is positioned so as to face the upper portion of the radiator R, the air flowing in from the ventilation opening 21 formed in the upper portion of the grill body 20 is disposed on the back surface 20A side of the grill body 20. The air guide plate 30 is deflected downward. The downwardly deflected air is effectively applied to the radiator R and can be efficiently cooled.

At this time, between the upper and lower ends of the grill main body 20, the blindfold 32 and the extension 40 of the air guide plate 30 are bridged, and the lower end 40A of the extension 40 is fixed to the grill main body 20 . The grill main body 20 is supported by the air guide plate 30 at the upper part 22 and the lower part 23. Thereby, the surface rigidity of the grill main body 20 whole can be improved.

  In particular, since the extended portion 40 is formed at the substantially central portion in the left-right direction of the air guide plate 30, the balance of rigidity in the left-right direction is improved, and the surface rigidity of the entire grill body 20 can be further improved.

In addition, since the extended portion 40 fixed to the lower portion 23 of the grill main body 20 faces the mounting bracket 12 that protrudes and extends from the upper surface of the bumper portion B, the extended portion 40 flows into the ventilation opening 21. It is difficult for air to get in the way, and a decrease in air permeability can be suppressed.

  On the other hand, since the ventilation portions 33 having a large number of ventilation holes 33A are formed on both sides of the blindfold portion 32 formed at the substantially central portion in the left-right direction of the air guide plate 30, air flows through the ventilation holes 33A. Can flow backwards.

  For this reason, it becomes difficult to inhibit the flow of air, and more air can be efficiently applied to the radiator R.

Furthermore, the baffle plate 30 towards the projecting, side view S of pre formed so as to protrude toward the extending portion 40 is a vehicle 10 located on the lower side after the blindfold portion 32 is a vehicle 10 located on the upper side Since it is in the shape of a letter, the air hitting the blindfold 32 can flow smoothly backward. As a result, turbulent flow is unlikely to occur in the air striking the air guide plate 30, and air can be efficiently applied to the radiator R, and generation of noise such as wind noise can be suppressed.

  Further, the blindfold 32 and the extension 40 of the air guide plate 30 are bridged between the upper and lower ends of the grill main body 20, so that the wind guide is provided across the upper and lower ends of the grill main body 20 as shown in FIG. 7. The plates 30 will face each other. Thereby, it becomes difficult to see the internal structure of the vehicle 10 from the ventilation opening 21 formed in the grill body 20, and the appearance can be improved.

In particular, the flange portions 42 that cover the side portions of the mounting bracket 12 extending from the bumper portion B are formed on both sides of the extending portion 40, so that even from the side of the vehicle 10. It is possible to make the internal structure difficult to see.

  The best mode for carrying out the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and is designed so as not to depart from the gist of the present invention. Modifications are included in the present invention.

  For example, in the above-described embodiment, the screw N is configured to pass through and fixed. However, the present invention is not particularly limited thereto, and may be fixed by welding, for example.
