<p><P>PROBLEM TO BE SOLVED: To align the axis of a valve in the tube axis direction with the axis of a resin tube without complicating structure. <P>SOLUTION: The tip 11 of the resin tube 10 can be inserted in a receptacle 5 for the connection of a valve box 2 of the valve 1, and an annular protrusion 12 is formed on the outer circumference of the tip 11. The outer circumference of the tip 11 is brought into contact with the inner circumference of the receptacle 5 for connection over the whole circumference, and the annular protrusion 12 abuts on the front end 5a of the receptacle 5 for connection in an insertion state. A hook 6 radially projecting outward is provided around the circumference of the receptacle 5 for connection, and the front end 15a of a tubular fastening member 15 is hooked on the annular protrusion 12. The rear end 15b and the hook 6 are fastened and fixed with a bolt 17 and the nut 18 to bring the annular protrusion 12 into press-contact with the front end 5a. The axes P<SB>2</SB>, P<SB>1</SB>of the receptacle 5 for connection and the resin tube 10 can be fixed to each other with the fastening member 15 so that the axes P<SB>2</SB>, P<SB>1</SB>can be easily aligned without complicating structure. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
