摘要： A flush toilet includes: a toilet body; a function unit arranged in a rear part of the toilet body; a panel member covering a side surface of the function unit and including a protruding part protruding toward the toilet body; and a holding part causing the toilet body and the panel member to hold to each other by magnetic force. The toilet body includes: a reception part arranged under the protruding part and receiving the protruding part in a state where the panel member is attached to the toilet body; and a protrusion part extending upward from the reception part. When the panel member is attached to the toilet body, the protrusion part is in a position where at least a part of the protrusion part is overlapped with the protruding part in a rear view when the toilet body is viewed from behind.

摘要： The water conduit has: a first water-guiding portion extending from a water supply portion, where the flush water is supplied to the water conduit, to a first spout port located on one of right and left sides of the bowl portion; and a second water-guiding portion extending from the water supply portion to a second spout port located on the other side. The water supply portion is located at a position on the one side. The flush water is supplied to the water supply portion in a direction from the water supply portion toward the first water-guiding portion. A collision wall is provided on a way of the first water-guiding portion such that at least a part of the supplied flush water collides with the collision wall. The at least part of the flush water having collided with the collision wall is supplied to the second water-guiding portion.

摘要： A flush toilet comprises a bowl including a shelf formed on the top edge of a bowl-shaped waste receiving surface, and a rim forming an inner wall surface rising from the outside edge of this bowl; and a rim spout portion for spouting flush water to the inside of the bowl. The rim spout portion is disposed on the bowl rim and forms a single rim spout port over the entire perimeter of the rim for spouting flush water, and the rim spout port is disposed on either the left or right of the front side region, and spouts flush water rearward. The region to the side of the rim spout port in the inner wall surface forms a continuous band over the entire bowl perimeter.

摘要： A flush toilet according to embodiments includes: a toilet body, a function unit, a panel member, and a holding part. The function unit is arranged in a rear part of the toilet body. The panel member covers a side surface of the function unit. The holding part causes the toilet body and a side surface of the panel member to attract and hold to each other by using magnetic force. In a state where being attached to the toilet body, the panel member is formed to be curved toward the toilet body. The holding part is formed such that an attraction surface of a panel-side magnetic material that is provided to the panel member and an attraction surface of a body-side magnetic material that is provided to the toilet body are formed in plane-shaped.

摘要： 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.
