Abstract: A flush toilet includes a bowl part, a drainage water trap part that is connected to a bottom part of the bowl part, and a water drainage socket that is connected to the drainage water trap part and includes an upper side water drainage socket that extends downward from the drainage water trap part, a back side R part that is connected to the upper side water drainage socket and changes a flow channel so that a washing water that flows from an upper side is directed to a front side, and a horizontal pipe that extends forward from the back side R part. The back side R part and the horizontal pipe include a water storage part that stores a part of washing water. The water storage part is arranged on a lower side of a back side lower end part of the drainage water trap part.

Abstract: A flush toilet includes a bowl part that includes a waste-receiving surface with a bowl shape that receives waste and a rim part that extends upward on an upper edge part of the waste-receiving surface, a first water-spouting port that spouts a washing water toward the rim part to form a first flow of a washing water that swirls on the waste-receiving surface, a second water-spouting port that spouts a washing water toward the rim part to form a second flow of a washing water that joins the first flow, and a connection part that includes a concave surface that connects the waste-receiving surface and the rim part and is curved to have a curvature that decreases from an upstream side to a downstream side of the first flow just before the first water-spouting port or the second water-spouting port in a flow direction of the first flow.
