PROBLEM TO BE SOLVED: To improve the ride comfort of an occupant and heat insulation by disposing a sound absorption sheet in a space between a vehicle roof and a molding ceiling positioned inside the vehicle roof to effectively reduce noise in a vehicle room.SOLUTION: A panel-shaped molding ceiling member 3 is disposed on the vehicle room inside of the roof panel R of a vehicle V. On the outer surface 3a of the molding ceiling member 3, a laminate molding 10 is molded so that the shape of the vehicle inside is roughly the same as that of the vehicle room outside of the molding ceiling member 3, and the shape of the vehicle room outside is roughly the same as that of the vehicle room inside of the roof panel R. The laminated molding 10 is configured by including a slab urethane layer 11, a film-like sheet layer 12 stacked on the vehicle room inside surface on the vehicle room outside surface of the slab urethane layer 11, and a mold urethane layer 13 stacked on the vehicle room inside surface on the vehicle room outside surface of the film-like sheet layer 12, and the vehicle room outside is pressed into contact with the vehicle room inside of the roof panel R in the fitted state to the roof panel R.SELECTED DRAWING: Figure 3

    【課題】車両のルーフと、この車両内方側に位置する成形天井との空間に吸音シートを配設して、更に車室内の騒音を効果的に低減して乗員の乗り心地感を向上させ、断熱性を高める。【解決手段】車両VのルーフパネルRの車室内方側にパネル状の成形天井部材3が配設されている。成形天井部材3の車室外側面3aには、積層成形体10がその車室内側の形状を成形天井部材3の車室外側の形状と略等しく、且つ、その車室外側の形状をルーフパネルRの車室内側の形状と略等しくするように成形されている。積層成形体10は、スラブウレタン層11と、スラブウレタン層11の車室外側面に、車室内側面で積層されたフィルム状シート層12と、フィルム状シート層12の車室外側面に、車室内側面で積層されたモールドウレタン層13とを備えてなり、ルーフパネルRに取り付けた状態で、車室外側がルーフパネルR車室内方側に圧接するようになっている。【選択図】図3
