摘要： PROBLEM TO BE SOLVED: To provide an interior trimming structure and interior trimming panel device, light-weighted, and restraining the amplitude of a solid sound without narrowing an effective space in the internal space of a structure. SOLUTION: An air permeable interior plate 3 having flowing resistance to prevent the amplitude of the solid sound emitted from a skeleton 1 is disposed opposite to the inner surface of the skeleton 1 of the structure with a gap from the inner surface of the skeleton 1 to vibrate independently. Preferably the interior plate 3 is formed with a plurality of holes or slits for flow resistance penetrating the opposite side surface from the skeleton confronting surface. The size of the hole 4 or slit is set so that the whole of hole 4a or slit serves as a viscosity boundary layer in a primary resonance frequency determined by the mass of the interior plate 3 and the elasticity of the gap. The skeleton confronting surface or opposite side surface of the interior plate 3 may be covered with an air permeable fabric 6, so that the flow resistance may be generated in the hole 4 or slit by the air permeable fabric 6.
