DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a luggage room structure for a vehicle.

[0002]

2. Description of the Related Art A luggage room of an automobile has a double floor structure in which a space is actively formed between a floor board placed on the rear floor panel by setting a low area on the rear floor panel. (See Japanese Patent Application Laid-Open No. 6-286671 as a similar technique). A lower spare tire pan is recessed in the lower area of the rear floor panel, and a spare tire is stored in the spare tire pan. The spare tire is fixed to the bottom surface of the spare tire pan, so that the spare tire does not jump out of the spare tire pan even when subjected to vibration during traveling. Low area of floorboard and rear floor panel (top of spare tire)
The space between them is used for storing small items and for storing the vehicle-mounted unit.

[0003]

However, in such a conventional technique, since a space is provided between the floorboard and a low area of the rear floor panel, the bending rigidity of the floorboard is ensured. For this purpose, a reinforcing member must be provided on the lower surface of the floorboard and a bracket having a predetermined height for receiving the reinforcing member must be provided in a low area of the rear floor panel, resulting in an increase in the number of parts.

Further, since a heavy spare tire is fixed to the bottom surface of the spare tire pan, due to the inertia of the spare tire, the entire rear floor panel vibrates up and down when the vehicle runs and the low frequency is uncomfortable. Generates a vibrating sound. In particular, such a membrane vibration of the rear floor panel is likely to occur in a wagon-type vehicle having a long rear overhang. In order to prevent such film vibration, it can be prevented to some extent by increasing the thickness of the rear floor panel and increasing the rigidity of the rear floor panel itself.However, this causes an increase in the weight of the vehicle body and the press formability of the rear floor panel. It is not preferable because it worsens. Further, there is a method of forming a leg for preventing film vibration of the rear floor panel on the lower surface of the floorboard. However, this method is not preferable because the structure of the floorboard is complicated.

The present invention has been made by paying attention to such a conventional technique, and it is possible to improve the flexural rigidity of a floorboard without increasing the number of parts and to suppress the membrane vibration of a rear floor panel. A luggage room structure.
