Abstract
In an incubator, in a state in which a door closes a porthole, a packing prevents an air current flowing between walls of a double-wall of a hood from entering the hood through a porthole in the inner wall. Therefore, the air current does not enter the hood through the porthole in the inner wall. In a state in which the door opens the porthole, because the packing separates from the porthole in the inner wall, the air current flows between the porthole in the inner wall and the porthole in the outer wall. Therefore, an air curtain is formed in the porthole. As a result, a suitable environment in the hood is invariably maintained in both of states in which the door closes and opens the porthole.
