Abstract
An apparatus is provided for regulating air pressure in an internal space of an airtight cabin that accommodates living beings (objects) for transport in a flight craft, comprising: a container; and a moveable partition member that airtightly partitions an internal space of the container into a first space open to the internal space of the airtight cabin and a second space closed to both the internal space of the airtight cabin and an external space of the airtight cabin, and that moves in the container under a force generated by a difference between a pressure of gas in the first space and a pressure of gas in the second space while maintaining the airtight partition between the first space and the second space; wherein as the moveable partition member moves it opens and closes a gas transfer path for flow of gas between the internal space of the airtight cabin and the external space of the airtight cabin.
