PROBLEM TO BE SOLVED: To simplify the structure of a door body, to reduce processes for totally closing operation and the time required for the totally closing operation and to improve watertightness between an upper flap and the door body. SOLUTION: When the upper flap 50 rises, a pin 54c-1a provided at an upper flat side bracket part 55 slides in a groove part 55b-2 provided in a door body side bracket 54. A flap side trolley wire part watertight rubber 57b is thereby moved together with the upper flap 50 laterally toward the upper flap adjacent part 21-2 side of the door body 21 and joined to a door body side trolley wire part watertight rubber 57a to store a trolley wire 5 in a storage groove 57a-1. The structure of the door body 21 is thereby simplified, the processes for totally closing operation of a watertight gate 1 for a railroad track and the time required for the totally closing operation can be reduced, and watertightness between the upper flap 50 and the door body 21 can be improved.
