<p>PROBLEM TO BE SOLVED: To provide a swivel joint unentangling in feeding tubes (hoses) of respective liquid in simultaneous or mixing atomization by supplying the two liquids and carrying out efficient work by reducing these resistance in operation of an atomizing gun body. SOLUTION: A male screw is arranged on the one end side outer periphery of a hollow pipe shaft. A connecting metal fitting for a fluid hose can be installed. A swivel tube coupling metal fitting is installed on the other end side to this. While an air introducing pipe is installed in a central part of the hollow pipe shaft so as to surround the outer periphery, the air introducing pipe has an air hose connecting metal fitting on one end side. Specific clearance is formed between the air introducing pipe and the hollow pipe shaft. Air passed through a valve element is guided and moved in the clearance. A tube ring receiving seat is rotatably installed on the other end side of the air introducing pipe via a ball bearing and an O ring. An air taking-out connecting metal fitting is installed on the tube ring receiving seat.</p> |
