PROBLEM TO BE SOLVED: To provide a water closet device that employs a system in which water is made to circle along a rim part formed at an upper edge part of a bowl part and then to flow down from the whole rim part toward the bowl part, and that can prevent the water from overflowing from the rim part while securing high washing performance by being configured to supply washing water to the rim part at a high flow rate by making good use of a jet pump operation.SOLUTION: A water closet device is configured to execute a first stage of supplying water to a discharge part at a first flow rate and a second stage of supplying water to the discharge part at a second flow rate smaller than the first flow rate during a process in which the water is supplied from a tank to the discharge part by a jet pump unit and a water level in the tank falls from a water full level down to a position of a suction port 321. A flow passage switching member 350 switches a flow passage state of the jet pump unit so that a jet pump operation in the second stage is suppressed more than a jet pump operation in the first stage. |
