する問題点があった。(c) Problems to be Solved by the Invention In such prior art, when an air-permeable sealant is used to block an exhaust port, in order to prevent the air-permeable sealant from shifting, it is necessary to tape it or use a seal with one-sided adhesive. Taping is difficult to work with, and sealing materials with adhesives have adhesive surfaces that significantly reduce the air venting effect.
There was a problem in that the amount of raw solution consumed was large. Furthermore, since the connecting parts between the inner and outer boxes and the connecting member are separately sealed using a different sealing material, there is a problem in that the workability during foaming is significantly reduced.
