[0007]

As described above, in the case of the conventional piping structure in the bubble bath, the main pipe section 101 is substantially horizontal.
Since the two branch pipes 104 are branched from one location, the number of parts required as a piping member is large, which causes a problem of cost increase.

[0008]

The invention of the present application has been made to solve such a problem. Thus, according to the invention of the present application, the bath water inside is taken out from the outlet provided in the bathtub to the outside through the bathwater pipe for extraction, and then is pumped to the bathtub side through the return bathwater pipe by the circulation pump, so that Bubbles which are supplied to two jet ports arranged adjacent to each other on the side wall of the side and suck air into the jet port through an air suction pipe so as to be jetted from the jet port as a jet flow containing bubbles. In the piping structure of the bathtub, the structure of the connection portion of the return bath water pipe to the jet outlet is divided into two branch pipes directly downward from different positions in the axial direction of the substantially horizontal main pipe portion. And the tip of the branch pipe is connected to each of the ejection ports (claim 1).

Another invention of the present application is the one according to claim 1, characterized in that one of the branch pipes is branched downward from a tip position of the substantially horizontal main pipe portion (claim 2).

According to still another aspect of the present invention, in claim 1, the branch pipe on the front end side of the main pipe portion is branched downward from a position retracted by a predetermined distance in the axial direction from the front end position of the main pipe portion. (Claim 3).
