PROBLEM TO BE SOLVED: To improve workability by enabling an overturn prevention component, which prevents a transom from overturning to an outdoor side with respect to a mullion, to be easily and reliably attached to the mullion.SOLUTION: A curtain wall includes: mullions; a transom that is attached between right and left mullions; a panel that is attached to an opening frame formed of the mullions and the transom; and an overturn prevention component that is attached to the mullion to support an outdoor-side lower end of the transom. A groove-like part with an opening end is formed in the mullion, and the overturn prevention component has an attachment part that is fitted into the opening end of the groove-like part.SELECTED DRAWING: Figure 3 |
