摘要： Disclosed is a floor panel structure for an automobile body, which comprises a floor panel (2, 4, 6, 12) joined to a plurality of frame members (22, 24, 27 to 32, etc.) extending in longitudinal and lateral directions of the automobile body so as to make up an automobile floor. At least a part of the floor panel has a panel zone (S1, S2, S4, S5, S6, S8) surrounded by the frame members. The panel zone includes a high-rigid portion (84) formed by deforming a central region thereof to protrude upward or downward, and a low-rigid portion (86) formed around the high-rigid portion. The high-rigid portion is formed with a concavoconvex element, such as a bead (90). The floor panel structure of the present invention can effectively reduce vibrational energy of a floor panel so as to reduce acoustic radiation from the floor panel.

摘要： A floor panel structure of a vehicle body where a vehicle floor has floor panels with their peripheral edges linked to a plurality of frame members that are disposed in a vehicle body lengthwise direction and a vehicle body crosswise direction and linked to an engine or a suspension is disclosed. The floor panel has a joint where at least part of its peripheral edge is joined to the frame member, a groove formed along the entire length of the joint and a high-rigidity area formed within the low-rigidity area. The low-rigidity area forms a vibration blocking area along the entire length of the joint by using a difference in rigidity from the high-rigidity area.
