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.

A frictional resistance reducing device of a ship, the frictional resistance reducing device comprising: a gas room provided in a hull to cross a longitudinal frame and to extend in a width direction of the hull;a scattering member arranged in said gas room to cross the longitudinal frame and to extend in the width direction; andan air supply pipe connected with said gas room,wherein air blows into said gas room from said air supply pipe, hits said scattering member and scatters in the width direction, and then blows from an air blowing hole provided in a bottom of said gas room into water,wherein a first opening is provided in a portion of said gas room on a port side from the longitudinal frame to connect an internal space of the hull and an internal space of said gas room,wherein a second opening is provided in another portion of said gas room on a starboard side from the longitudinal frame to connect the internal space of the hull and the internal space of said gas room,wherein a first lid is provided for said first opening, and a second lid is provided for said second opening,wherein a first part of said scattering member which is a part of said scattering member on the port side from the longitudinal frame, and a second part of said scattering member which is a part of said scattering member on the starboard side from the longitudinal frame are separable from said scattering member, andwherein said first part of said scattering member has such a size that said first part of said scattering member is possible to pass through said first opening, and said second part of said scattering member is such a size that said second part of said scattering member is possible to pass through said second opening. 2. The frictional resistance reducing device according to claim 1, wherein said first opening and said second opening are formed in an upper member of said gas room, and said air supply pipe is connected with said first lid or said second lid. 3. The frictional resistance reducing device according to claim 1, wherein said first part of said scattering member is attached to said first lid, and said second part of said scattering member is attached to said second lid. 4. The frictional resistance reducing device of according to claim 1, wherein said first opening and said second opening are formed in a longitudinal side member in a longitudinal direction of said gas room,wherein said longitudinal side member is a side member of said gas room on a bow side or a stern side of said gas room, andwherein said air supply pipe is connected with an upper member of said gas room. 5. The frictional resistance reducing device according to claim 1, wherein a bow side slit hole is formed on a bow side of said scattering member to extend in the width direction,wherein a stern side slit hole is formed on a stern side of said scattering member to extend in the width direction, andwherein the air blows into said gas room from said air supply pipe, passes through the bow side slit hole or the stern side slit hole, and blows from said air blowing hole into the water. 6. A ship comprising a frictional resistance reducing device of a ship, the frictional resistance reducing device comprising: a gas room provided in a hull to cross a longitudinal frame and to extend in a width direction of said hull;a scattering member arranged in said gas room to cross said longitudinal frame and to extend in the width direction; andan air supply pipe connected with said gas room,wherein air blows into said gas room from said air supply pipe, hits said scattering member and scatters in the width direction, and then blows from an air blowing hole provided in a bottom of said gas room into water,wherein a first opening is provided in a portion of said gas room on a port side from said longitudinal frame to connect an internal space of said hull and an internal space of said gas room,wherein a second opening is provided in another portion of said gas room on a starboard side from said longitudinal frame to connect the internal space of said hull and the internal space of said gas room,wherein a first lid is provided for said first opening, and a second lid is provided for said second opening,wherein a first part of said scattering member which is a part of said scattering member on the port side from said longitudinal frame, and a second part of said scattering member which is a part of said scattering member on the starboard side from said longitudinal frame are separable from said scattering member, andwherein said first part of said scattering member has such a size that said first part of said scattering member is possible to pass through said first opening, and said second part of said scattering member is such a size that said second part of said scattering member is possible to pass through said second opening.
