Title:
VEHICLE BODY FRONT STRUCTURE
Document Type and Number:
Japanese Patent JP2004237920
Kind Code:
A
Abstract:

To provide a vehicle body front structure capable of suppressing the rear deformation of an extension member in relation to the input of a load from the front without causing an excessive increase in weight and the deterioration of assembling workability.

The extension rear member 10 of closed cross section structure extending in a vehicle body fore-and-aft direction is provided on the upper side of a floor panel 6. The extension rear member 10 is coupled with the floor panel 6. A floor member 11 is provided on the rear side of a lower side bent part 3a of the extension member 3. The floor member 11 is coupled with the upper side of the extension rear member 10 by being overlapped on the side. By forming the floor member 11 by casting a light alloy and making an upper surface 11a thick, the section modulus and the proof stress moment of the floor member 11 are improved to suppress the rear deformation of the extension member 3 in relation to the load inputted from the front.
