PROBLEM TO BE SOLVED: To avoid direct exposure to the eyes when using a carbon dioxide gas supply cylinder, which forms a lotion mixed with carbon dioxide, to wipe off unnecessary awkward feeling and feeling of anxiety and further to effectively work a jetting gas pressure of the carbon dioxide gas supply cylinder for opening/closing of a nozzle part.SOLUTION: In a facial treatment apparatus, carbon dioxide gas guided through a flexible hose P from a carbon dioxide gas supply cylinder B is made to jet out from a jet nozzle at the tip end of a spray body, and then, together with a lotion in a cup, the lotion mixed with carbon dioxide is jetted while being atomized. On the upper side surface of an upper cylindrical body 1, an internal thread is formed in the inner side surface of a mounted circular adjusting knob. Further, on the upper side surface of the upper cylindrical body 1, a boss is stood which has a diameter smaller than the outer diameter of the upper cylindrical body 1. An external thread is formed on the outer periphery of the boss, and threadedly engaged with the internal thread of the circular adjusting knob, and thereby, the circular adjusting knob is rotated and vertically moved. Further, a non-threaded groove is formed between the upper side surface of the upper cylindrical body 1 and the external thread of the boss, and there is formed a fall-off prevention screw, which is screwed from the side face of the circular adjusting knob and in which the tip end is situated in the non-threaded groove. |
