PROBLEM TO BE SOLVED: To provide an air bubbles generating bathtub provided with a jetting nozzle reducing the pressure rise by collision of water streams themselves and of the water stream with the wall surface in the inside of the nozzle, and securing a sufficient air suction by an ejector action while continuously changing jetting directions. SOLUTION: The air bubble generating bath tub is provided with a branched flow-rate control means branching bath water fed from a circulating pump into two directions of a first branched bath-water forcedly-fed flow passage and a second branched bath-water forcedly-fed flow passage and variably adjusting the amount of branched bath water to the respective flow passages, and a controller continuously varying the jetting direction of the jetting nozzle by operating the branched flow-rate control means. The one or more jetting nozzles are respectively connected to both of the first and the second bath-water forcedly-fed flow passages, and one end of an air taken-in part is communicated and connected to each of the first and the second bath-water forcedly-fed flow passages immediately before the first and the second bath-water forcedly-fed flow passages are communicated and connected to the jetting nozzles, and within a range of possibility of suctioning air by the ejector action.
