PROBLEM TO BE SOLVED: To provide a flush closet bowl which reduces the amount of water supply needed for restoring the water level to its initial level after flushing. SOLUTION: The flush closet bowl 1 comprises: a bowl part 2 having a jet hole 6 and a trap entrance; a trap conduit for communicating the trap entrance with a drain path; a rim part 4 for allowing the flush water to flow down to the bowl part 2; a jet flush water tank 8 for storing the flush water for the jet hole 6; a jet drain valve 9 for supplying the flush water to the jet hole 6 and stopping it; a jet water guide path 10 for guiding the flush water from the drain valve 9 to the jet hole 6; a rim flush water tank 11 for storing the flush water for the rim part 4; a rim drain valve 12 for supplying the flush water to the rim part 4 and stopping it; and a rim water guide path 13 for guiding the flush water from the rim drain valve 12 to the rim part 2. The jet water guide path 10 has a substantially horizontal pipe line having a ceiling part which is substantially as high as an upper end part of the trap entrance. COPYRIGHT: (C)2007,JPO&INPIT
