Abstract
A flush toilet includes a bowl including a rim formed on the top edge of a bowl-shaped waste receiving surface; and a rim spout portion disposed on the rim for forming a circulating flow by spouting flush water into the bowl. The bowl further includes a shelf between the top edge of the waste receiving surface and the bottom end of the rim, and a connecting surface for connecting the outside edge of this shelf and the bottom end of the rim with a curved surface. The connecting surface is arranged so that the curvature radius of its curved surface in the vertical direction is essentially constant from the bowl front portion across both the left and right sides, and so that its position rises toward the left and right sides from the front portion of the bowl.
