PROBLEM TO BE SOLVED: To obtain high noise insulation performance without impairing productivity of a vehicle when providing a sound absorption material 41 as noise insulation measure for road noise propagated to a vehicle interior space via a wheel house 15.SOLUTION: In a vehicular noise insulation structure, a support part 51 is provided to a trim member 31 so as to project toward a wheel house inner 16 from a back face of the trim member 31 to support the sound absorption material 41 so that the sound absorption material is partially directed along the wheel house inner 16 while being alienated from the back face of the trim member 31.SELECTED DRAWING: Figure 5
【課題】ホイールハウス15を経由して車室内空間に伝播するロードノイズの防音対策として吸音材41を設ける場合に、車両の生産性を悪化させることなく、高い防音性能が得られるようにする。【解決手段】トリム部材31に、該トリム部材31の裏面からホイールハウスインナ16に向かって突出して、吸音材41を、該トリム部材31の裏面から離間させかつホイールハウスインナ16に部分的に沿うように支持する支持部51を設ける。【選択図】図5
