Abstract
A water-inflow prevention device is provided by installing a closing lid 6 for blocking a duct 2 of an air pressure regulating valve 1, which regulates air pressure inside a cabin 101. A buoyant body 9 is attached to the disc-shaped closing lid 6 installed to the duct 2 so as to be rotatable around a rotation shaft 7. The buoyant body 9 receives a buoyant force from water when immersed in the water. Since the side of the closing lid 6 in which the buoyant body 9 is attached is thereby floated in the water, the closing lid 6 automatically rotates around the rotation shaft 7 so as to close a ventilation port 2a.

1-2. (canceled)
A water-inflow prevention device of an aircraft for preventing water inflow from an air pressure regulating valve in an occasion when the aircraft lands on water,
- the air pressure regulating valve being provided in the aircraft to regulate air pressure inside a cabin, and comprising a vent passage for connecting an inside and outside of the aircraft and a valve body installed in an inside of the vent passage,
- wherein the air pressure regulating valve is rendered to be an obstacle with respect to the water inflow without being operated by a pilot of the aircraft, and
- wherein the obstacle gets a motion in an occasion when the aircraft lands on water, and blocks the vent passage.
