<P>PROBLEM TO BE SOLVED: To provide a floor panel structure of a vehicle body, capable of increasing rigidity of an article storage part without the need of other members, controlling a resonance frequency, compatibly reducing weight of the vehicle body and controlling the resonance frequency, and improving an NVH performance. <P>SOLUTION: A floor panel 10 includes: an article storage part 23 formed by being projected downwards at a position separated by a gap at least from frame members 19 and 19 disposed at both sides in a vehicle width direction among frame members; and first connection parts 31 and 31 on both sides in the car with direction, for connecting the upper end part 25a of an article storage wall part 25 and connection parts 10LE and 10RI. An article storage bottom part 24 is a curved surface projected upwards or downwards, the upper end part 25a of the article storage wall part 25 is positioned below, in the vertical direction, the connection parts 10LE and 10RI of the floor panel 10 and the frame members 19 and 19 on both sides in the vehicle width direction, and a large portion of at least one first connection part 31 is formed of a flat surface or a curved surface inclined downwards. <P>COPYRIGHT: (C)2013,JPO&INPIT |
