Abstract: To provide a floating flap gate that requires an auxiliary force of a counterweight or the like, and in which bending does not occur in a forward end portion of a door body, even in cases in which an installation site has a wide span. A floating flap gate 1 having a forward end portion 2c of a door body 2 that is configured to rotate around a base end portion serving as a fulcrum at a time of a rising water, so as to float upwards, and provided with an upper beam 2d attached to the forward end portion 2c of the door body 2 and a door body suspension member 3 contained within the upper beam 2d, and having two ends each being connected to one end of a wire rope 4. A counterweight 5 is connected to the other end side of the wire rope 4 as a pulling device. Bolts 6b are used as adjusting members interposed between the upper beam 2d and the door suspension member 3, and are inserted into bolt holes 6a provided on an upper surface of the upper beam 2d, so as to exert an opposing force to the tension of the wire rope 4 resulting from the weight of the counterweight 5 acting on the door body suspension member 3, the opposing force being applied uniformly to the upper beam 2d during ordinary use.
