摘要： A flush toilet for discharging waste using flush water supplied from a flush water source is disclosed. The flush toilet comprises a bowl portion including a rim portion, and a shelf portion formed between the rim portion and a waste receiving surface; a water discharge path for discharging waste; a water spouting portion for spouting flush water onto the shelf portion of the bowl portion to form a swirl flow; and a water conduit for supplying flush water to the spouting portion. The water spouting portion is formed on the rim portion, and a first swirl trajectory of a first circulation and a second swirl trajectory of a second circulation are mutually different when flush water spouted from the water spouting portion swirls along the rim portion.
