PROBLEM TO BE SOLVED: To provide a pantograph mechanism for flexible partitions for a building, which is hard to cause deformation or damages under wind pressure or the like. SOLUTION: In the pantograph mechanism for the flexible partitions for a building, a plurality of movable links 5, 6 using a square cylindrical pipe comprising a pair of opposite parallel walls and another pair of opposite orthogonal walls are made adjacent to each other, and connected to the parallel walls 5b, 6b of the movable links 5, 6 tiltably through a support shaft 10. A collar 20 is inserted on the support shaft 10 between the parallel walls 5b, 5b of the adjacent movable links 5, 6, and the collar 20 has a size allowing the extension part of the collar to reach the orthogonal walls 5a, 5a of the movable links 5, 6. A reinforcing piece 30 is inserted into the connection part through which the support shaft 10 is inserted, inside the movable links 5, 6. The reinforcing piece 30 has a square cylindrical shape similar to the movable links 5, 6 and also has a size to be tightly adhered to the inner walls of the movable links 5, 6 and formed with a hole through which the support shaft 10 penetrates.
