  • the rim water outlet (4) is adjusted to direct the tributaries and concentrate the flow of water.
  • the present invention has been made in view of the above-mentioned problems of the prior art, and the object thereof is that even if the size and position of the rim water outlet vary, the variation in the flow direction of the tributary can be reduced. Providing flush toilets that can concentrate the flow of water And to.
  • a ball surface shape of a rear bottom portion of a ball portion of a toilet body is formed to have a substantially V-shaped cross section.

  • the downstream side (32a) of the installation surface is eccentric in the direction of the rising path (33) by the amount of protrusion of the step surface (9).
  • the step surface (9) protrudes in a three-month plane along the inner circumference of the descending path (32) for about half a circumference, and is approximately perpendicular to the flowing direction of the settling water. It protrudes.
  • the trap drainage channel (3) has such a structure that the washing water flowing into the drainage channel (3) and flowing down the descending channel ( ⁇ ) collides with the stepped surface (9) and then downstream. Will flow down in an eccentric state, The upstream side of the step surface in the trap drainage channel (3) can be more reliably filled with water. Therefore, a small amount of water is supplied to quickly cause a siphon action, thereby allowing the dirt in the ball portion to flow out at once.
