に巻き込まれる。As shown in FIGS. 7 and 8, the width of the hole 47 on the side of the tubular structure formed by the first end 31 and the second end 32 is 4.
Narrower than the width on the 5th side. Further, since a large number of holes are provided surrounding the tubular structure, the opening area of each hole with respect to the tubular structure is small. Therefore, in this nozzle, when this nozzle L is not used, hot water inside the tubular structure rarely enters the chamber 45 side through these holes 47. Furthermore, the hole 47 is provided near the connecting side of the first end 31, which has an inner diameter larger than the second end 32, as shown in FIG. In other words, since the water flow that enters at a higher flow rate than the second end 32 is provided in the area where it is expanded at this connecting part, the fluid pressure becomes negative on the inner surface of the hole 47 due to the principle of fluid continuity, so that the chamber 45 air is entrained in this water flow.

2万々以上の超音波を発生する。The water stream containing the air is ejected from the opening edge 44 of the front piece 41 into the hot water in the bathtub. The inside of this opening edge 44 is 2
It has a diffuser shape with an angle of inclination of 10° to 10°, and by spreading the jet water flow in this way, when the air caught in the water flow is released into the hot water in the bathtub, it becomes even more fine. Crush and disperse into bubbles. During this crushing and dispersion, more than 20,000 ultrasonic waves are generated.
