Claims

[Scope of Claim for Utility Model Registration] A nozzle casing whose front end is connected to the side wall of the bathtub body in a watertight manner, a throat which is swingably disposed at the front part within the nozzle casing, and a throat disposed in the middle part of the nozzle casing. A cylindrical body for forming a valve seat equipped with a valve seat, an aeration space interposed between the valve seat and the throat and communicating with the air intake section, and an aeration space provided at the rear of the nozzle casing and communicating with the aeration space through the valve seat. A bubble-generating bathtub is equipped with a bath water inflow space, a valve body disposed in the bath water inflow space so as to be able to move toward and away from a valve seat, and a nozzle valve body opening/closing motor that moves the valve body forward and backward. In the nozzle structure, a water-sealing gasket is interposed between the outer circumferential surface of the valve seat forming cylinder and the inner circumferential surface of the nozzle casing, and between the air mixing space and the bath water inflow space. A jet nozzle structure in a bubble-generating bathtub characterized by:
