  FIG. 1 shows a radiator grille mounting structure according to the present invention. A front bumper facer 11 is provided on the upper part of the front bumper, and a flat part 12 is formed on the upper part of the front bumper facer 11. The flat portion 12 is formed with a step hole 13 whose rear side is higher than the front side in the vehicle longitudinal direction. In FIG. 1, the left side is the front of the vehicle and the right side is the rear of the vehicle. Although not shown in the drawing, the step hole 13 has a rectangular shape when viewed from above.

  A radiator grille 14 is disposed above the front bumper fascia 11, and the bottom part of the radiator grille 14 is attached to the flat part 12 of the front bumper fascia 11. Further, a blindfold plate 15 protruding rearward is provided on the upper portion of the radiator grille 14, and the attachment portion between the radiator grille 14 and the front bumper fascia 11 is blindfolded by the blindfold plate 15.

  A rib 16 bent backward is provided at the bottom end of the radiator grill 14, and the rib 16 is disposed along the flat portion 12 of the front bumper fascia 11.

  The blindfold plate 15 and the ribs 16 are made of synthetic resin and are provided integrally with the radiator grille 14.

  A mounting member 17 is provided at the bottom rear end of the radiator grille 14. A bent portion 17A that is bent in a crank shape is provided at the front portion of the mounting member 17, and an engaging protrusion that engages with the step hole 13 of the flat portion 12 of the front bumper fascia 11 at the lower end of the bent portion 17A. 18 is attached. Here, the attachment member 17 is fixed to the bottom rear end of the radiator grille 14 and forms a part of the radiator grille 14.

  In this embodiment, the engagement protrusion 18 is attached to the bent portion 17A of the attachment member 17. However, since the attachment member 17 is a part of the radiator grille 14 as described above, the engagement protrusion 18 is the radiator grille. 14 is attached to the bottom surface.

  As shown in FIG. 4, the engaging protrusion 18 is entirely formed of a synthetic resin. As shown in FIG. 4, a plate-like member 19 disposed along the vehicle width direction and both left and right ends of the plate-like member 19 (along the vehicle width direction). Fixed guides 20 and 21 provided at both ends). The distance from the side surface of the fixed guide 20 to the side surface of the fixed guide 21 (that is, the width of the engagement protrusion 18) is substantially equal to the width of the step hole 13 along the vehicle width direction.

  The fixed guides 20 and 21 have the same shape. When viewed from the side (in the direction of the arrow A1 or A2 in the figure), the fixed guides 20 and 21 are narrow at the bottom and wide at the top, and on the rear side, the inclined surfaces 20A and 20A, 21A is formed. When the engaging protrusion 18 is inserted into the step hole 13, the inclined surfaces 20 </ b> A and 21 </ b> A guide the engaging protrusion 18 and fix it to the step hole 13.

  Further, on the front surfaces of the fixed guides 20 and 21 (surfaces opposite to the inclined surfaces 20A and 21A), stepped portions 20B and 21B that protrude forward are formed. These step portions 20B and 21B come into contact with the front edge portion 13A of the step hole 13 provided in the front bumper fascia 11 when the engaging protrusion 18 is inserted into the step hole 13 (see FIG. 5).

  Further, a claw support 22 is formed at the center of the plate-like member 19 of the engaging protrusion 18. Only the base 22A of the nail support 22 is connected to the plate-shaped member 19 main body, and between the left and right side surfaces of the nail support 22 and the plate-shaped member 19 main body, and the upper surface of the nail support 22 and the plate-shaped member 19 main body. Gap G is formed between the two. For this reason, when a force in the direction of arrow B is applied, the claw support 22 is elastically deformed forward with the base 22A as the center.

  A claw portion 23 is formed on the rear surface of the claw support 22 (the rear surface along the vehicle front-rear direction). The claw portion 23 has a substantially right-angled triangular cross section, and an inclined surface 23A is provided at a portion locked to the rear edge 13B of the step hole 13 (see FIG. 5).

  Next, the operation at the time of removing the radiator grille 14 from the front bumper fascia 11 in the radiator grille mounting structure having the above configuration will be described.

  First, when the engagement protrusion 18 on the bottom surface of the radiator grille 14 is engaged with the step hole 13 of the front bumper fascia 11, the engagement protrusion 18 is formed on the inclined surface 23A of the claw portion 23 as shown in FIG. Comes into contact with the rear edge 13B of the step hole 13, and the contact resistance S acts on the contact point S in the downward assembly state. As a result, the engagement protrusion 18 is locked in the step hole 13.

  When removing the radiator grille 14 from the front bumper fascia 11, when the worker stands in front of the vehicle and starts pulling up the blindfold 15 toward the front side (in the direction of arrow C in FIG. 1), the engagement protrusion 18 Rotate about the initial rotation center O1 of the front ends of the step portions 20B and 21B. When the engaging projection 18 rotates about the initial rotation center O1, the rear edge 13B of the step hole 13 pushes the inclined surface 23A of the claw part 23 obliquely, and the rear edge 13B The surface resistance Q at the time of rotation generated between the inclined surface 23A can be reduced.

  When the blindfold 15 is further pulled in the direction of arrow C as shown in FIG. 2, the elastic claw support 22 is slightly deformed forward around the base 22A, and the rear edge 13B of the step hole 13 is Then, it is pushed up by the inclined surface 23A of the claw portion 23 and slightly deformed upward. In this state, when the blindfold plate 15 is continuously pulled up in the direction of arrow C, the front ends of the step portions 20B and 21B of the engagement protrusion 18 are separated from the front side edge portion 13A of the step hole 13, and the entire radiator grill 14 is at the tip of the rib 16. Starts to rotate around the rotation center O2.

  When the entire radiator grille 14 is further rotated about the rotation center O2, the rear edge 13B of the step hole 13 is disengaged from the inclined surface 23A of the claw 23 as shown in FIG. Moreover, the nail | claw holding | maintenance part 22 of the engagement protrusion 18 returns to an original position as shown with a broken line in the figure with the elastic force. Thereby, the engagement state of the engagement protrusion 18 by the step hole 13 is released, and the radiator grille 14 can be removed from the front bumper fascia 11. FIG. 3 shows a state where the radiator grille 14 is removed from the front bumper fascia 11.

  According to the present embodiment, in the fixed guides 20 and 21 at both ends of the engagement protrusion 18, the wide portions are positioned above the step portions 20 </ b> B and 21 </ b> B, respectively. When rotated around O1, the step hole 13 can be expanded by the fixed guides 20 and 21, and the engaging protrusion 18 can be easily pulled out of the step hole 13.

  Further, since the blindfold plate 15 is provided on the upper portion of the radiator grille 14, the operator simply pulls up the blindfold plate 15 without directly touching the claw portion 23 of the engagement protrusion 18 so that the radiator grille 14 is moved to the front bumper fascia. 11 can be easily removed. Moreover, since there is the blindfold board 15, it contributes to the appearance improvement.

  Further, the operation of pulling up the front end portion of the blindfold plate 15 and removing the radiator grille 14 from the front bumper fascia 11 is engaged with the front end portion of the blindfold plate 15 as the point of action and the rotation center O2 at the end of the rib 16 as a fulcrum. The so-called lever principle using the protrusion 18 and the step hole 13 as an action point is used. Therefore, the radiator grille 14 can be detached from the front bumper fascia 11 with a small operating force.

  In addition, according to the present embodiment, since it is not necessary to insert a jig or the like between the radiator grille 14 and the front bumper fascia 11, a gap of about 1 mm is provided between the radiator grille 14 and the front bumper fascia 11. Just do it.
