Abstract: A flush toilet has a reservoir tank, a toilet main unit, a water supply apparatus, a water discharge apparatus, and a control device for controlling flushing of the bowl portion of the toilet main unit; wherein this control device includes a time measurement device for measuring the time after the water discharge apparatus has been driven for a predetermined time to discharge flush water, until the water level rises from a dead water level inside the reservoir tank with the water discharge apparatus in an off state to a predetermined stopped water level prior to start of flush; and the driving time of the water discharge apparatus responsive to pressure losses in the toilet main unit is adjusted by comparing the water level rise time measured by the time measurement device with the water level rise time in a standard toilet.

Abstract: To provide a flush toilet in which: a circulating flow can be formed to uniformly circulate over a waste receiving surface while flushing; localized changes in external appearance of a toilet main body can be inhibited; and impression of a left-right symmetrical external shape can be conveyed to users so that design characteristics thereof are favorably preserved. A rim portion in a flush toilet includes a slit opening portion formed between an upper edge portion of the waste receiving surface formed to be left-right asymmetrical and a rim inside wall formed to be left-right symmetrical. The slit opening portion is formed such that a slit gap on one side, to which a connecting water conduit is directed, is smaller than a slit gap on the other side. A circulating flow is formed on the waste-receiving surface by flush water spouted from the slit opening portion having the different slit gaps.
