A flush toilet includes a reservoir tank assembled from above or behind to a predetermined installation position on the rear side of the conduit of a toilet main unit; a connecting pipe member, one end of which is disposed on the conduit of the toilet main unit, and the other end of which is connected to a reservoir tank; a tank-side connecting portion, disposed on the front side of the reservoir tank and connected to a connecting pipe member; and a seal member, connected in a watertight manner between a connecting pipe member and a tank-side connecting portion.

A flush toilet apparatus for discharging waste by a jet pump action is disclosed. The flush toilet apparatus has an overflow portion configured to overflow a portion of flush water flowing from a throat pipe into a water conduit into a reservoir tank so that when the flow rate of water flowing inside the throat pipe exceeds a predetermined specified flow rate, the flow rate of water supplied from the water conduit to a bowl portion is reduced to less than a predetermined specified flow rate.
