Abstract
A gas room is arranged in a hull to cross a longitudinal frame and extend in a width direction. A scattering member is arranged in the gas room to cross the longitudinal frame and extend in the width direction. Air blown into the gas room from an air supply pipe hits the scattering member to scatter in the width direction, and is blown from an air blowing hole formed in a bottom of the gas room into water. Because the gas room crosses the longitudinal frame and extends in the width direction, an air bubble flow with a wide width forms in the width direction by the single gas room. Therefore, the number of gas rooms for air bubble flow which covers the whole width of a ship bottom is reduced, and the number of air supply pipes which are provided to every gas room is reduced.
