PROBLEM TO BE SOLVED: To eliminate the problem described below in a water closet having a jet pump, when the duration of syphon is longer than the duration of jet pump, that is, it is longer than the period of rolling-in of water in a storage section due to the design of external appearance, the performance of internal configuration of trap or the like or water supply condition, water in the storage section disappears during the continuation of the syphon, and thus the jet flow becomes weak in the middle of syphon, and the function of supporting the jet current created by the jet pump becomes weak in the middle, and the function to support the dirt ejection by syphon is degraded and the function to support the dirt ejection by syphon is degraded and the dirt ejecting capacity is degraded in some case and this must be eliminated. SOLUTION: Timing for drive completion of the jet pump, that is, the timing for completing the state of turning the washing water prepared for dirt carrying of the ball portion into a fluid to be driven provided for the dirt carrying of the ball portion is located behind the completion timing of the syphon occurring in the water closet.
