欠点があった。2. Description of the Related Art Conventionally, as a flush toilet of this type, a water tapping side of a ball tap provided in a water supply tank is branched into a tank water supply port and a makeup water port, and a makeup water port is overflowed in the water supply tank. While the water is being supplied from the tank water supply port to the water supply tank, the supply water discharged from the water supply port is connected to the overflow pipe and the water supply pipe connecting the water supply tank and the toilet body to the inside of the ball portion. Is known to return the water retained in the ball portion to a predetermined water level after the ball washing is completed (see, for example, FIG. 1 of Japanese Utility Model Laid-Open No. 57-38874). However, in this conventional reservoir supply structure,
The amount of makeup water discharged from the makeup water port is affected by the water pressure fluctuation on the ball tap entrance side, and when the water pressure is low, the water in the ball portion cannot be returned to the predetermined water level, so that a reliable water sealing effect cannot be obtained, On the other hand, when the water pressure is high, there is a disadvantage that the increased water is discharged from the outlet of the ball portion to the outside, which is uneconomical.

なる虞れがあった。In order to solve such an old disadvantage, Japanese Utility Model Laid-Open Publication No. Sho 57-38874 discloses that a part of the water supplied from a water supply tank is stored in a water supply section formed behind a toilet body. In addition to forming a sump chamber for water supply, an extremely small outflow hole is formed at the lowest position of the sump chamber to supply supply water from the water supply tank to the rim water passage through the sump chamber. Along with performing the ball cleaning, a part of the supply water stored in the reservoir is discharged from the outflow hole after the ball cleaning is completed, and the stored water in the ball portion is not affected by the water pressure fluctuation on the ball tap inlet side. It has been proposed to reliably return to a predetermined position. However, according to this prior art, since the supply water from the water supply tank is once stored in the reservoir chamber and then supplied to the rim water passage, the force of the water due to the head pressure in the water supply tank is reduced. Therefore, there is a disadvantage that the power for discharging the waste in the ball portion is weakened. In addition, it is necessary to make the hole diameter of the outflow hole extremely small (10 mm or less in diameter) so that the outflow of makeup water from the outflow hole is performed after the completion of the ball washing. A water film is easily formed, and when used in a cold region or the like, there is a possibility that the water film freezes and the outflow hole is closed, so that the intended purpose cannot be achieved.

ことができる。As described above, the flush toilet of the present invention is constructed as described above, and a part of a predetermined amount of water supplied from a water supply source such as a water supply tank or a flush valve is supplied to a water supply passage (supply water flow passage). Since the water is retained in the water and the water is continuously sprayed after the ball cleaning is completed, the stored water in the ball portion can be reliably returned to the predetermined position without being affected by the water pressure fluctuation of the ball tap inlet side of the water supply tank or the flash valve. Moreover, since the washing water is sprayed onto the ball portion via the rim water passage without receiving any flow resistance, the washing water is not weakened by the supply pressure from the water supply source, in other words, the water by the supply pressure is not affected. By effectively utilizing the momentum, the waste in the ball portion can be reliably discharged. Furthermore, the flow resistance means provided in the makeup water flow path delays the makeup water from reaching the rim water passage so that the makeup water is continuously sprayed from the spray hole after the ball washing is completed. There is no need to separately form holes or separately process specific water injection holes for injection of make-up water. Therefore, a water film is formed on the small-diameter hole, and supply water is not supplied due to freezing due to use in a cold region or the like,
The above-described effects can be obtained while eliminating the drawbacks of the prior art in which the design and processing of the water injection hole requires much time and makes the production troublesome.
