PROBLEM TO BE SOLVED: To surely clean the surface of a bowl part and discharge filth by a very small amount of flush water in a siphon jet toilet tool. SOLUTION: As a passage of water from a washing tank 310, a conduit S1 constituted by a flushing water feed hole 40, a flushing water introducing passage 41, a diverging hole 42, a jet conduit 46, a jet hole 22, a rim conduit 43 and a water emitting hole 44 is formed in the interior of this siphon jet toilet stool 10. When flushing water from the flushing tank 310 having a tank actual volume of 4 l in large flushing and a tank actual volume of 3 l in small flushing is supplied through the flushing water feed hole 40 to the flushing water introducing passage 41, the flushing water is favorably distributed to the jet water introducing passage 46 and the rim water introducing passage 43 by the diverging hole 42. As a result, flushing water sufficient to cause a siphon action early and continuously is jetted from the jet hole 22, and flushing water sufficient to wash the surface of the bowl part 20 is discharged from the water emitting hole 44.
