PROBLEM TO BE SOLVED: To provide a duct structure capable of avoiding direct adjacency of each RoRo compartment by providing a dead space (VOID space) in a tier-shaped stair part ventilation duct where each RoRo compartment adjoins directly in a ventilation duct connected to a fire fighting compartment positioned on a lower layer of an automobile carrier, and capable of avoiding a thermal protection construction into the ventilation duct.SOLUTION: Concerning an air duct b3 for ventilation in a bow lower layer deck fire fighting compartment and in a midslope lower layer deck fire fighting compartment of an automobile carrier, the air duct upper surface is provided with a dead space on an area adjoining to vehicle loading decks 2c, 2d, 2e in the air duct b3, used jointly for the vehicle loading decks (vehicle decks) 2c, 2d, 2e.SELECTED DRAWING: Figure 1

    【課題】自動車運搬船の下層に位置する消火区画に接続される通風ダクトのうちRoRo区画同士が直接隣接するひな壇形状の階段部通風ダクト内に空所(VOIDスペース)を設け、RoRo区画同士の直接の隣接を避け、かつ、当該通風ダクト内への防熱施工を回避することができるダクト構造を提供する。【解決手段】自動車運搬船の船首下層デッキ消火区画及び中腹下層デッキ消火区画の換気用通風ダクトb3であって、当該通風ダクト上面が車両積載甲板(車両デッキ)2c、2d、2eに兼用される当該通風ダクトb3内の前記車両積載甲板2c、2d、2eの隣接域に空所を設けてなる。【選択図】図1
