Claims

[Scope of Claim for Utility Model Registration] 1. A case that is attached to a mounting opening opened in the tank wall and has an open side facing the tank, and in which an air suction connecting part and a water flow restricting part are sequentially arranged in the rear part, and the case. a nozzle attached to the downstream side of the water flow constriction part via an elastic spring within the nozzle, a flow direction converting body attached so as to be able to slide against the outer peripheral surface of the nozzle, and the flow path direction changing body. and an annular sealing material provided around the inner peripheral surface of the case which is held between the nozzle and the nozzle on which the repulsive force of the repulsive force acts, A spherical guide surface formed, a protruding retaining portion provided around the end opposite to the inside of the tank, a positioning flange provided around the end opposite to the outside of the tank, and an ejection hole penetrating through both the opposite ends. Several types of nozzles with different thicknesses of positioning flanges are prepared with the basic shape as shown in FIG. a cover body having a hemispherical outer shell that has an inward flange that slides in contact with the nozzle at the open end and covers the nozzle through a clamping space between the protruding retaining part and the annular sealing material; and the spout hole of the cover body. 1. A bubble generator for a bathtub, comprising: a flow path conversion hole formed in a portion facing the flow path converting hole; 2. A bubble generating device for a bathtub, characterized in that the nozzle according to claim 1 has a protruding retaining portion having a different thickness instead of having a different positioning flange thickness. 3. A bubble generator for a bathtub, characterized in that one type of nozzle according to claim 1 is used, and several types of flow direction converters having different inward flange thicknesses are prepared.
