The partition wall 11h is screwed 12 to the inner peripheral wall 11a-1 of the casing 11a. In the partition wall 11h, the outer peripheral portion 11h-1 of the air mixing nozzle 11c is formed in a hexagonal shape so that the screwing operation at the time of assembly can be facilitated.

In the present invention jetting tool 11, the large-diameter hot water supply pipe 13 on the upstream side is joined to the large-diameter connection port 11f by brazing, and the small-diameter joint port 11f and the small-diameter hot water supply pipe 14 on the downstream side. Are joined by brazing, etc. On the other hand, the jetting device 11 of the present invention has a small diameter hot water supply pipe 14 on the downstream side joined to the small diameter joint 11f by brazing or the like. The large-diameter hot-water supply pipe 13 and the small-diameter hot-water supply pipe 14 are appropriately selected in their inner diameter dimensions so that the amounts of hot water supplied to both of the present invention jetting tools 11, 11 are equal.

When there is an error in the mounting position of the jetting tools 11, 11 and / or an error in the installation position of the bathtub 1, etc., the tips of the hot water supply pipes 13, 14 are introduced from the hot water supply pipe joint openings 11f into the introduction chamber 11e. These errors can be absorbed by adjusting the insertion size. The small-diameter hot water supply pipe 14 has a bellows portion 14a formed in the middle thereof so that it can be easily bent. When the jetting tools 11 and 11 of the present invention are attached so as to cross each other (not shown), they can be easily piped by bending the bellows portion 14a of the hot water supply pipe 14 having a small diameter. The air supply pipe 5 is joined to both of the present invention ejectors 11 and 11.

The large-diameter hot water supply pipe 13 is joined to a suction tool (not shown) provided in the bathtub 1, and a circulation pump (not shown) is arranged in the middle thereof. The hot water supplied by the large-diameter hot water supply pipe 13 due to the activation of the circulation pump is guided to the introduction chamber 11e of the one main ejection device 11, and a part of the hot water is introduced into the aeration nozzle of the one main ejection device 11. 11c, and the rest is distributed to the hot water supply pipe 14 having a small diameter. The hot water distributed to the small-diameter hot water supply pipe 14 is guided to the introduction chamber 11e of the other sprayer 11 of the present invention and is supplied to the air mixing nozzle 11c. Since both of the present invention ejectors 11 and 11 have the same amount of hot water supplied, the amounts of hot water ejected from the ejection ports 11b and 11b are equal. Therefore, with this piping structure, the momentum of the hot water spouted from the spouting tools 11 and 12 of the present invention into the bathtub 1 becomes equal, and the user can enjoy a pleasant bath.

Second Embodiment FIGS. 2 and 3 show a second embodiment of the present invention ejector, FIG. 2 is a partially sectional plan view of the present invention ejector, and FIG. It is the front view which carried out the partial cross section which shows the piping state which was.
