PROBLEM TO BE SOLVED: To provide a curtain wall which prevents the occurrence of a displacement difference in the outward direction in a vertical frame having a projection and a vertical frame having no projection, both of which are adjacent to each other from side to side, when it receives a load directed in the outward direction. SOLUTION: The vertical frame 10 on one side of a frame 4 of a curtain wall unit 1 has a projection 20, and the vertical frame 11 on the other side does not have the projection 20. Then an engagement part 30 is attached across the space between the vertical frame 10 on one side and the vertical frame 11 on the other side, both of which are adjacent to each other from side to side. Thus, both of the vertical frames 10, 11 are prevented from moving relatively in the outward direction. COPYRIGHT: (C)2009,JPO&INPIT
