拡大を防がなければいけない。[Prior Art] Particular care is taken when entering and exiting contaminated areas at nuclear facilities and the like. When entering the room, an airline suit is worn, and when leaving the room, one or three rooms with low contamination levels are set up, where the contamination level is gradually lowered and the contamination level is measured to ensure that the contamination is removed. After confirming that everything has been completed, leave the room. This is the method used to enter and exit the contaminated room when fishing on a boat, but it is especially important to prevent the spread of contamination by exiting.
[発明が解決しようとする問題点コ

ことにもなる。In addition, there are cases where contamination is being removed in rooms with low contamination levels and measurements are being taken to confirm the decontamination.
In particular, there is a problem in that it takes a lot of time to leave the room. This also leads to a decrease in the efficiency of work that requires repeated entry and exit from the isolation room.
また作業者が退出する毎に脱いだ汚染された作業衣ある
いは使い捨てにされる資材すなわち汚染廃棄物が増える
という問題もある。There is also the problem that each time a worker leaves the facility, the amount of contaminated work clothes removed or disposable materials, ie, contaminated waste, increases.

れる。In the manufacturing process, the screws 5 and 8 are inserted into this space and then a presser 17 is screwed in. If the screw is a right-handed screw, if the screw continues to be rotated clockwise, the screw head 18 will press against the space wall 19. Conversely, if the screw head 18 continues to rotate counterclockwise, the screw head 18 will press against the presser 17. Note that FIG. 4 is an enlarged view of part (a) in FIG. 3. As is clear from the above configuration, if the screws 4 and 5 are continued to be rotated clockwise, lO and 12 will be connected, and at the same time, 7 and 8 will be rotated counterclockwise to connect 11 and 13. Also, at this time, 8 and the lid frame 12 are separated, and at the same time, 5 and the lid 11 are separated.
