PROBLEM TO BE SOLVED: To provide a water closet apparatus with high designability that improves washability in a narrow toilet booth, storage properties for cleaning tools, and constructability, and achieves size reduction of a tank.SOLUTION: A water closet apparatus includes a jet pump unit 300 in a tank, and the jet pump unit has a throat pipe 320 in an inverted U shape which is connected to an inlet port of a duct through a duct inlet port connection part while one end penetrates an opening, and has a suction port 331 formed at the other end, and a nozzle 310 which induces a jet pump operation by jetting water at a high speed from the suction port into the throat pipe. A valve unit is arranged in the tank, the throat pipe 320 in the inverted U shape has a vertical throat part 351 extending upward substantially vertically from the duct inlet port connection part, and an inclined throat part 330 inclined downward linearly and obliquely from the vertical throat part toward the suction port, and a supply flow rate reduction valve 340 is provided in the tank. |
