The actual situation is that the speaker grill 1 is attached around the opening 5 of the rear parcel shelf 2.

[0005]

As described above, in the conventional mounting structure of the speaker grill 1, although the speaker grill 1 is fixed to the rear parcel shelf 2 as the interior trim, the rear parcel as the vehicle body panel is used. Since it is not directly fixed to the panel 3, as shown in FIG.
When a force F is applied to the front side of the rear parcel shelf 2, the rear parcel shelf 2 is deformed downward, so that the clearance between the speaker grill 1 and the speaker unit 4 cannot be kept constant, and It is pointed out that this causes a decrease in the number.

Further, the speaker grille 1 is screwed into the mounting bosses 6 projecting from the rear surface thereof from the rear side of the rear parcel shelf 2, so that the effective dimensions of the mounting screws 7 are secured. The size of the boss 6 must be set to be long, so that the surface of the speaker grill 1 tends to excessively protrude from the surface of the rear parcel shelf 2, making it difficult to set a thin speaker grill 1.
It has been pointed out that the speaker grill 1 is greatly restricted in the degree of freedom in shaping.

[0007] The present invention has been made in view of such circumstances, and it is possible to always maintain a constant clearance between a vehicle body panel and a speaker grill, to ensure good sound quality, and to improve interior quality. It is an object of the present invention to provide a speaker grill mounting structure that does not cause a gap between the trim and a trim, and that can greatly improve the degree of freedom in modeling.

[0008]

In order to achieve the above-mentioned object, the present invention relates to a resin molded body attached to cover an opening of an interior trim opened corresponding to a speaker unit fixed to a vehicle body panel. In the speaker grill mounting structure, a panel mounting leg and a trim mounting claw are provided at predetermined positions on a rear edge of the speaker grill, and a resin clip mounted on a tip of the panel mounting leg is attached to a vehicle body. The speaker grille is attached to the vehicle body panel and interior trim by fitting it into the mounting hole of the panel by press-fitting and engaging the trim mounting claw with the locking hole provided outside the opening of the interior trim. I do.

Further, according to the present invention, a trim engaging claw is provided on a side surface of a panel mounting leg provided on a back surface of a speaker grill, and the panel mounting leg is inserted through a through hole of an interior trim.
When passed through, the above-mentioned trim locking claw piece is inserted into the through hole of the interior trim.
The panel mounting leg is attached to the interior trim by engaging with the edge .

[0010]

As is apparent from the above configuration, the ends of the panel mounting legs integrally formed on the back surface of the speaker grill are mounted on the vehicle body panel via the resin clips, so that the panel mounting legs serve as stoppers. It functions, and the clearance between the speaker grill and the vehicle body panel can be always kept constant.

In addition, the relationship between the speaker grill and the interior trim is such that a trim mounting claw integrally provided on the rear surface of the speaker grill is engaged with a locking hole of the interior trim, and therefore, as in the prior art, The thickness of the speaker grill can be set to be thin, instead of a screw-fixed configuration.

Further, even when an external force that bends and deforms the interior trim, the speaker grill attached to the interior trim via the trim mounting claw is fixed to the vehicle body panel via the panel mounting leg. Therefore, it is possible to suppress the bending deformation of the interior trim and to prevent the occurrence of a gap between the interior trim and the speaker grill.
