PROBLEM TO BE SOLVED: To provide a flush toilet bowl for enabling floating sewerage in a bowl part to be agitated with reserved water and efficiently discharged into a drainage line, thus improving its sewerage discharging performance.SOLUTION: A flush toilet bowl 1 according to this invention includes a bowl part 8 including a sewerage receiving face 16, a rim portion 18, and a recessed portion 20 formed below the sewerage receiving face, a first rim discharge part 22 for discharging swirl-flow water, a second rim discharge part 24 for discharging swirl-flow water swirling in the same direction, and a drainage line 12 for discharging sewerage. The bowl part is constructed to form a main flow M11 so that washing water discharged from the first discharge part flows from the front side of the bowl part into the recessed portion and to form a flow M2 so that washing water discharged from the second discharge part agitates reserved water in the recessed portion in the vertical direction. In a rear side region of the bowl part, a rear side recessed portion 40 and/or a first induction path 42 are formed to make the washing water discharged from the second rim discharge part and swirling in the bowl part, into flows M21, M22 directed to the bottom face of the recessed portion. |
