  • Publication number: 20220275627
    Abstract: A flush toilet includes a toilet main body and a control unit. The toilet main body includes a skirt, a rear storage configured to store at least a part of the control unit, and an opening to which a drain pipe is connected is formed penetrating, in a front-rear direction, a portion below a center in a left-right direction of a rear wall of the skirt. The rear storage forms a discharge socket storage on a front side of the opening in a region below a center of the rear storage in the left-right direction. And a side wall surface in the discharge socket storage protrudes more in a center direction of the opening than a side wall surface in the opening, to reduce an opening cross-sectional area of the discharge socket storage to be smaller than an opening cross-sectional area of the opening.
