SILENCING APPARATUS AND METHOD FOR MANUFACTURING SILENCING APPARATUS

A silencing apparatus (1) is provided with: a shell (2): ventilation pipes (3, 4) that are connected to the inside of the shell (2); insertion holes (5, 6) which are formed to the shell (2) so as to have a size smaller than skirt parts (51, 61) therearound and through which ventilation pipes (3, 4) are loosely inserted; and partitions (7, 8) that divide the inside of the shell (2), wherein at least a sound-absorbing chamber (10) divided by the partition (7) and adjacent to the insertion hole (5) is filled with a sound-absorbing fiber material (9), and a sound-absorbing fiber material filling gap (13) between the insertion hole (5) and the ventilation pipe (3) is closed by an annular closing material (14). Thus, it is possible to provide a silencing apparatus in which the sound-absorbing chamber can be filled with a sound-absorbing fiber material without any space even in the case of a complex structure where the inside of the shell is divided by partitions. 消音器(1)具备：壳体(2)；通气管(3、4)，与壳体(2)的内部连通；插通孔(5、6)，以比周围的下摆
