PROBLEM TO BE SOLVED: To provide a diversion port gate in which a diversion port can be opened/closed easily and a seal member is adhered closely with sufficient pressure, thereby preventing the leakage of water in the case where the diversion port is closed.SOLUTION: A diversion port gate 100 is provided in a diversion port of an agricultural water channel. A guide member 110 comprises: a door body 160 which includes a diversion port hole and gate body lock parts in both side ends, and to which a seal member adhered closely to an edge of the diversion port hole is fixed; a compression coil spring 150 held in the door body 160; a tension plate 140 which is mounted to the compression coil spring 150 so as to be interlocked with an extension/contraction state of the compression coil spring 150, and of which both the ends are supported by the gate body lock parts; a lever 130 which is joined to a substantially central part of the tension plate 140 for controlling the extension/contraction state of the compression coil spring 150; and a lever fixing member 180 which is provided in an upper portion of the door body 160 for fixing and holding a position of the lever 130. The door body 160 closes the diversion port hole with pressure of the compression coil spring. |
