PURPOSE:To improve a vibro-damping effect without increase of a weight by making many holes in a vibro-damping member and applying a vibro-damping material as much as a volume of the holes onto an area except the holes for increasing a height. CONSTITUTION:A vibro-damping member shaped like a sheet is closely fit to a panel 1 and many holes 3 are made in a face of said sheet-like vibro-damping plate 2. A vibro-damping material as much as a volume of the holes is uniformly applied onto an area except the holes 3, thereby increasing an entire thickness of the vibro-damping member 2 without increasing an entire volume of the member 2. This provides reduction in weight of a whole vibro-damping structure and achievement of an improved vibro-damping effect. |
