To provide a sound isolation door capable of further reducing noise.
The sound isolation door 28 to close an opening part comprises a door body and a seal mechanism 40. The seal mechanism 40 has a roller 44, means 42, 43 to support the roller 44 movably in a predetermined area, and a means 46 to press an outer circumferential surface of the roller 44 against an opening edge 64 of the opening part closed by the sound isolation door 28. In the sound isolation door 28, the pressing means 46 presses the outer circumferential surface of the roller 44 against the opening edge 64 of the opening part to be closed by the sound isolation door 28 while the supporting means 42, 43 of the seal mechanism 40 support the roller 44 movably in the predetermined area. Thus, the roller 44 is moved to the position at which the outer circumferential surface is tightly fitted to the opening edge 64, and stabilized in the state. Noise is further reduced thereby.
