PROBLEM TO BE SOLVED: To provide a water closet device that employs a style in which washing water is supplied to a bowl part by a jet pump and that can suppress noise generated by a tank.SOLUTION: A water closet device FT has flow passage changing means of making change from a first state in which water jetted from a nozzle 310 is supplied from a suction port 331 into a throat pipe 320 and a second state in which the water jetted from the nozzle 310 deviates from the suction port 331 to be supplied into the tank 20. When the water level in the tank 20 lowers, the flow passage changing means makes change from the first state to the second state before the water level lowers to a lower-limit water level LV1 at which air flows in the throat pipe 320 from the suction port 331. |
