To provide a light-weight silencer for vehicle which includes a fiber material and partially has the high rigidity.SOLUTION: A silencer 1 for vehicle comprises a press-molded fiber material 100 and is installed between a vehicle body panel 80 and a skin material (50) having a rear surface 51. The fiber material 100 includes a general part 20 which has a surface 21 along the rear surface 51 of the skin material (50) and an uneven part 30. The uneven part 30 includes a concave surface 32 which is recessed toward a direction apart from the rear surface 51 of the skin material (50) between a first apex 31a along the rear surface 51 of the skin material (50) and a second apex 31b along the rear surface 51 of the skin material (50). The concave surface 32 includes: a bottom part 33; a first inner side surface 34 between the first apex 31a and the bottom part 33; and a second inner side surface 35 between the second apex 31b and the bottom part 33. The uneven part 30 has a clearance CL1 between the first inner side surface 34 and the second inner side surface 35.SELECTED DRAWING: Figure 2
【課題】繊維材を含み部分的に高い剛性を有する軽量の車両用サイレンサーを提供する。【解決手段】車両用サイレンサー1は、プレス成形された繊維材100を含み、車体パネル80と、裏面51を有する表皮材(50)と、の間に設置される。繊維材100は、表皮材(50)の裏面51に沿った表面21を有する一般部20、及び、凹凸部30を備える。凹凸部30は、表皮材(50)の裏面51に沿った第一の頂部31aと、表皮材(50)の裏面51に沿った第二の頂部31bと、の間で表皮材(50)の裏面51から離れる向きに凹んだ凹面32を有する。凹面32は、底部33、第一の頂部31aと底部33との間にある第一の内側面34、及び、第二の頂部31bと底部33との間にある第二の内側面35を含む。凹凸部30は、第一の内側面34と第二の内側面35との間に隙間CL1を有する。【選択図】図2
