Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a flush toilet bowl which can make siphonage occur early and discharge dirt through the use of a small quantity of water, and which can smoothly carry dirt and the like after generation of the siphonage.SOLUTION: An inventive flush toilet bowl 1 has a trap drainage channel 6 including an upright upper pipeline 12 and an upright lower pipeline 14. The flush toilet bowl 1 has a bending pipeline 18 connected to the lower end of the upright upper pipeline 14 of the trap drain 6 and a lateral drain pipeline 20 connected to the downstream end of the bending pipeline 18 and having the downstream side extending to the rear of the toilet bowl. The bending pipeline 18 is formed in such a manner that: in the cross-sectional area of a water passage through which washing water of the bending pipeline 18 flows, the cross-sectional area of a water passage on one side with respect to an axis line A0 of a center in the lateral direction of the bending pipeline 18 is smaller than that of a water passage on the other side. |
