り確実に防止することかできる。Next, the operation of this revolving door 1 will be explained with reference to schematic plan cross-sectional views of FIGS. 3(a), 3(b), and 3(c). In other words, when a person enters the clean room R from the air shower area A,
First, as shown in FIG. 3(a), the rotary inlet/outlet 31a is aligned with the inlet/outlet 21a of the wall portion 2 to enter the groove space 4. At this time, the inner entrance/exit 21b is sealed by the rotating wall 3b. Furthermore, by increasing the amount of air supplied to the groove space 4 and making the inside of the door space 4 more positive than the inside of the air shower area A, the air in the air shower area A can be prevented from entering the door space 4. This can be prevented more reliably.

A person enters the clean room R by aligning it with the entrance/exit 21b of the clean room R. At this time, the outer entrance/exit 21a is sealed by the rotating wall 31. Furthermore, by reducing the amount of air supplied to the groove space 4 and making the inside of the door space 4 a negative pressure compared to the inside of the clean room R, it is possible to more reliably prevent the air inside the door space 4 from entering the clean room R. can do.
又、クリーンルームＲから出る場合には上記順序と逆の
順序をたどればよい。Moreover, when leaving the clean room R, the above order may be reversed.
