摘要

PROBLEM TO BE SOLVED: To provide a multiple window opening device which has sufficient water cutoff performance and draining performance while reducing the number of members. SOLUTION: The multiple window opening device is provided with: a frame body which is installed along a building opening, a plurality of panels attached to the frame body; and a connecting frame provided between panels of the plurality of panels. The connecting frame is provided with: a seal part provided in at least a part of the connecting frame; an internal conduction path extending through the connecting frame and conducting with at least the part of the connecting frame where the seal part is provided; and an internal drain port provided in at least a part of the internal conduction path. The frame body is provided with: a hollow part provided within the frame body; and an external drain port penetrating through the frame body from the hollow part to the outside of the frame. The connecting frame is combined with the frame body so that the internal conduction path of the connecting frame communicates with the hollow part of the frame body through the internal drain port.
