　The flap gate is a backflow prevention gate that moves by natural water pressure with a hinge at the top of the door as a fulcrum and is used for a relatively small gutter pipe。
　The gate leaf which is made of FRP has a specific gravity of about 1/5 that of SS400 and is lightly movable by the the low water level difference , suppresses the water flow obstruction rate when draining, and improves backflow prevention efficiency when water is stopped.
