摘要：
The present invention aims to provide a muffling structure of a vent pipe and a muffling structure of a case, which is capable of muffling in a wide frequency range and preventing vent resistance in the air pipe or the case from deterioration. Vent holes (11a) are formed in the peripheral wall of the vent pipe (11), a cover (12) is so provided on the peripheral wall of the vent pipe (11) as to cover the vent holes (!1a), and a bag-like body (13) in which activated charcoal (14) is contained is disposed in the space formed by the peripheral wall of the vent pipe (11) and the inner wall of the cover (12).
