浄水の勢いによってトラップ排水路内にサイホン作用を
起こして汚物を排出するようになっている（第６図）。(Prior art) Conventionally, this type of flush toilet is provided with a rim water passage 4 at an upper end periphery of a ball portion 1 having a trap inlet at a lowermost rear portion,
The rim water outlet 3 is spaced from the bottom wall 4a of the rim water passage 4
The siphon action is generated in the trap drainage channel by the force of the washing water sprayed from each rim water outlet 3 to discharge waste (FIG. 6).
（発明が解決しようとする課題） 上述した水洗便器において洗浄水の給水量を必要最小

こすための相当量（10〜15程度）の給水を必要とし、
節水性に優れているとは言い難いものであった。However, in reality becomes weak cohesion force of wash water tributaries a 1 because variations in the direction of the washing water tributaries a 1 occurs due curvature of the ball surface 1a, thus, a considerable amount for causing the siphon action (10 ~ 15) water supply,
It was hard to say that it was excellent in water saving.
本発明は上述した従来事情に鑑みてなされたものであ
り、その目的とする所は、洗浄水支流の結束力を強くし

ている。1 to 4 are not related to the scope of the claims of the present invention, but are shown as reference examples for explaining the basic structure. In the figure, A is a toilet body having a ball portion 1 and a trap drainage channel 2 provided adjacent to the ball portion 1. Rim water outlet 4 with rim water outlet 3 and ball section 1
Protrude inward and trap drainage channel 2
It has a siphon-type flush toilet structure in which an outlet 6 formed on the rear bottom surface of the toilet main body A is bent in a substantially S-shape to communicate therewith. A dirt drop recess 7 is formed at the rearmost portion of the ball portion 1, and the trap inlet 5 is opened at the rear side surface of the dirt drop recess 7.

がきわめて容易である等、多くの効果を奏する。(Effect of the Invention) Since the present invention is configured as described above, the siphon action is generated in the trap drainage channel by increasing the binding force of the cleaning water tributary sprayed from the forefront side of the rim water channel. Therefore, there is no need for extra water supply to concentrate the momentum of the wash water tributaries that vary widely like conventional toilets, and a water-saving flush toilet with excellent water saving that can reliably generate a siphon action even with a small amount of water supply. Can be provided. Furthermore, since the water passage guide surface can be extended by a simple means of simply attaching a cylindrical member to the rim water outlet, there are many effects, such as extremely easy manufacture.
