PROBLEM TO BE SOLVED: To provide a float glass manufacturing apparatus capable of preventing a glass ribbon from cracking in an interface unit.SOLUTION: A manufacturing apparatus of float glass includes a shaping unit 10 for shaping a tabular glass ribbon G on molten metal M in a bath 11, an annealing unit 20 for annealing the glass ribbon G, and an interface unit 30 for connecting the shaping unit 10 and the annealing unit 20. The interface unit 30 is equipped with lift-out-rolls 33-1, 33-2, 33-3 for drawing up the glass ribbon G from the molten metal M and conveying it toward the annealing unit 20, a cooling member 36 for cooling the downstream end 11a of the bath 11, and an insulation member 37 for blocking cold radiation to the glass ribbon G from the cooling member 36.SELECTED DRAWING: Figure 1 【課題】インターフェース装置でのガラスリボンの割れを防止できるフロートガラス製造装置を提供する。【解決手段】浴槽１１内の溶融金属Ｍ上において板状のガラスリボンＧを成形する成形装置１０と、前記ガラスリボンＧを徐冷する徐冷装置２０と、前記成形装置１０と前記徐冷装置２０とを接続するインターフェース装置３０とを備え、前記インターフェース装置３０は、前記溶融金属Ｍから前記ガラスリボンＧを引き上げると共に前記徐冷装置２０に向けて搬送するリフトアウトロール３３−１，３３−２，３３−３と、前記浴槽１１の下流端部１１ａを冷却する冷却部材３６と、前記冷却部材３６による前記ガラスリボンＧの冷輻射を遮る断熱部材３７とを有する、フロートガラス製造装置。【選択図】図１
