Abstract
A water-inflow prevention device is provided by installing a closing lidfor blocking a ductof an air pressure regulating valve, which regulates air pressure inside a cabin. A buoyant bodyis attached to the disc-shaped closing lidinstalled to the ductso as to be rotatable around a rotation shaft. The buoyant bodyreceives a buoyant force from water when immersed in the water. Since the side of the closing lidin which the buoyant bodyis attached is thereby floated in the water, the closing lidautomatically rotates around the rotation shaftso as to close a ventilation port
