PROBLEM TO BE SOLVED: To provide a corrugation movable weir capable of reducing a construction space and preventing the lowest point in the upper edge of a flexible sheet from getting lower than the lowest point in the upper edge of a rigid plate while it is a simple structure. SOLUTION: The corrugation movable weir is equipped with the rigid plate for cutting off the central part of a water-way, the flexible sheet for cutting off the bank of the water-way and a driving means making the rigid plate corrugate to the bottom of the water-way, and a folding section is formed in the vicinity of side edges A<SB>10</SB>and A<SB>11</SB>of the rigid plate. Side edges B<SB>10</SB>and B<SB>11</SB>on one side of the flexible sheet are fixed to the side edges A<SB>10</SB>and A<SB>11</SB>of the folding section, and side edges B<SB>10</SB>and B<SB>12</SB>on the other side of the flexible sheet is fixed to a surface of slope of the bank section of the water-way.
