PROBLEM TO BE SOLVED: To provide a flush toilet bowl device which is equipped with a small-sized minute bubble generating device that can uniformly mix gas into flushing water by a gas mixing section, and can uniformly generate minute bubbles by a minute bubble generating section. SOLUTION: According to the structure of the flush toilet bowl device, an inclined peripheral surface 20 is formed on an external peripheral surface of a jet nozzle 14 protruding into a gas mixing chamber 6 so as to be inclined toward the center of a flushing water channel 3 as it goes to a downstream side. Then the gas mixing section 4 is formed by making a gas exit port 13a of a gas feeding passage 13 face a location of the gas mixing camber 6, that corresponds to a maximum diameter portion 20a of the inclined peripheral surface 20 in a flushing water flowing direction, or to a location of the gas mixing chamber 6 that is on the upstream side of the maximum diameter portion 20a of the inclined peripheral surface 20. Further a diameter restricted portion 16 of a venturi tubular channel 15 formed in the flushing water channel 3, is connected to the downstream side of the gas mixing chamber 6, and the minute bubble generating section 5 is formed of a diameter extended section 17 of the venturi tubular channel 15.
