WIPO Patent Application WO/2013/094691

Kind Code:

A1

Abstract:

Provided is a front floor panel composed of a lightweight metal plate which can be reliably press-formed without the load during press-formation becoming excessive, and the desired rigidity and acoustic vibration characteristics can be achieved in all directions because there is little anisotropy of rigidity. A front floor panel (110) of an automobile body comprises a floor tunnel (104a) formed extending longitudinally in the middle of the vehicle width direction, left and right upward flanges (104b) formed in the left and right vehicle-widthwise ends and used for bonding with side sills (105), and left and right flat parts (104c) formed between the left and right upward flanges (104b) and the left and right vertical walls of the floor tunnel (104a). In annular areas including the outer edges of the flat parts (104b), uneven-shaped parts (111) of a specific shape are formed, and the remaining areas excluding the annular areas are formed into flat plate shapes.
