Abstract: A vibration damping structure includes a panel which is a structure and a damping member joined to the panel. The damping member has a plurality of joined portions joined to a mating surface of the panel through respective joined surfaces in the X direction, and a plurality of spacing portions recessed toward the side opposite to the panel in the Z direction between adjacent joined portions. The damping member is formed such that the damping member is higher in damping than the panel and a resonance frequency of the damping member is formed such that it is substantially the same as a primary resonance frequency of the panel.

Abstract: Disclosed is a rear vehicle body structure of a vehicle, which comprises a rear floor panel, and a rear side frame joined to a lower surface of the rear floor panel to extend in a front-rear direction. A bottom wall of the rear side frame has a bottom reinforcing portion formed to protrude upwardly or downwardly, and a standing wall of the rear side frame located on a vehicle-widthwise inner side has a side reinforcing portion formed to protrude outwardly in the vehicle width direction. The bottom reinforcing portion includes a top, an outer inclined section extending from the top obliquely outwardly in the vehicle width direction, and an inner inclined section extending from the top obliquely inwardly in the vehicle width direction, wherein the inner inclined section has an inclination angle less than an inclination angle of the outer inclined section.

Abstract: Floor panel vibration is reduced by suppressing a mode in which an entire region surrounded by a plurality of frame members in a floor panel vibrates. Vehicle-body framework members having closed cross-section structures, and a panel member to which vibration is transmitted from an engine or/and a suspension via the vehicle-body framework members are provided. The panel member includes a flange portion having a planar shape on its outer peripheral edge and to which the vehicle-body framework members are joined along the panel outer peripheral edge; a curved surface portion that is curved such that a place closer to a panel central side bulges out more to a lower side in a continuous manner from a panel-central-side edge portion of the flange portion; and a flat surface portion that extends to the panel central side from the panel-central-side edge portion of the curved surface portion in a continuous manner.
