PROBLEM TO BE SOLVED: To obtain a miniaturized flush toilet bowl and having high economization in water consumption without using a power source in the flush toilet bowl supplying jet flush water jetting toward a trap from a jet hole formed in the bottom of a bowl surface by making use of the water head pressure of water stored in a low tank by supplying bowl flush water for washing the bowl surface by making use of the supply pressure of a water supply pipe when the toilet bowl equipped with a large water storage surface is washed. SOLUTION: In the flush toilet bowl equipped with a first manual operated mechanism opening and closing a bowl flush water valve and a jet flush water valve by the operation energy of a user, the first manual operated mechanism includes a rotational body equipped with a cam driving the bowl flush water valve and the jet flush water valve, a first operating section making a toilet bowl washing operation, a spring storing energy for operating the first operating section, a torque transfer section transferring the energy stored in the spring to the rotational body and a speed setting means connected to the rotational body, varying energy consumption and setting the speed of the rotational body.
