PROBLEM TO BE SOLVED: To provide a jet pump type flush toilet bowl device having improved design quality by improving the washability in a narrow toilet booth, the ability of storing cleaning tools, the workability of a toilet bowl and a water supply pipe, and the ride-in acceptability and easy rotation activity of a wheelchair, while optimizing the structure and arrangement of a jet pump unit and reducing the size of a tank.SOLUTION: The tank is arranged on the rear side upper part of a toilet bowl body 10. Inside the tank, there are arranged a throat pipe 320, a jet pump unit 300 having a nozzle 310 for inducing jet pump operation, and a valve unit VU for supplying/cutting off water to/from the nozzle 310. The tank is formed longer in the horizontal direction of the toilet bowl body 10 than in the longitudinal direction. In a one-side space in the horizontal direction of the tank, the throat pipe 320 is arranged in the horizontal direction in a top view, and in the other-side space, a float 238 is arranged for controlling the valve unit VU. This can reduce the size of the tank while maintaining high jet pump performance. |
