Abstract

To shorten the longitudinal length of a flush toilet with a sure siphonage. A connection drain pipe constitutes a drain flow passage extending from a toilet bowl drain port (2d) communicating with a first water sealing part (4a) formed in the bowl (2) of a toilet bowl body (1) to a floor drain port (70a) formed in a floor drain pipe (70) raised from a floor surface (F). The connection pipe body (65) of the drain pipe comprises a first downstream flow passage (65a), a re-upstream flow passage (65b), and a second downstream flow passage (65c). The first downstream flow passage (65a), the re-upstream flow passage (65b), and the second downstream flow passage (65c) are spirally formed while keeping the positional relation of a first position A and a second position C.
