In the present invention, preferably a flush toilet for cleaning toilets and discharging filth, a water storage tank for storing wash water, a bowl-shaped filth receiving surface, and an inner peripheral surface formed at the upper edge A rim portion formed so as to rise in an overhanging shape or a substantially vertical direction, a drainage channel having an inlet connected to the lower portion of the bowl portion for discharging dirt, and an inner periphery of the rim portion A toilet body including a rim water spouting portion that spouts washing water to form a swirling flow, and a water conduit that guides the washing water stored in the water storage tank to the rim water spouting portion . waterways, adjustable throttle member as cross-sectional flow area of about the water channel feedwater flow is large decreases in the water tank is provided, the diaphragm member, and is formed in a separate member from the above toilet bowl above Can be attached to and removed from the toilet body , When the water supply flow rate of the water storage tank is smaller than a predetermined value, characterized in that removal.
In the present invention configured as described above, when the water conduit is provided with a throttle member that can be adjusted so that the water flow cross-sectional area of the water conduit becomes smaller as the water supply flow rate of the water storage tank is larger,
The throttle member can be removed when the water supply flow rate of the water storage tank is smaller than a predetermined value, so that an appropriate water supply flow rate for cleaning the toilet bowl is provided even when a water storage tank that generates a relatively small water supply flow rate is attached. Can be supplied to the bowl. Therefore, in the toilet bowl in which the inner peripheral surface of the rim part of the bowl part is formed in an overhang shape or rises in a substantially vertical direction, the water supply flow rate of the wash water discharged from the rim water discharge part is reduced. The momentum of the washing water swirling the portion becomes weak, and it is possible to prevent the bowl portion from being unable to be sufficiently washed.

Claims
