<P>PROBLEM TO BE SOLVED: To provide a flexible tube capable of maintaining sufficient strength without only depending on welding fixation. <P>SOLUTION: The flexible tube1 1 is provided with: a corrugated hose 2 having an outer circumference whose entire surface is nearly covered with a wire braid 3; a copper tube 4 which is welded, fixed and connected to at least one end of the corrugated hose; and a collar 5 which is fitted and inserted by covering the outer circumference of an end of a connection side of the corrugated hose and the wire braid. The end of the connection side of the copper tube 4 is formed into an enlarged diameter part. The head of the enlarged diameter part is welded, fixed, and connected the corrugated hose, and the end of the copper tube side of the collar is formed into a reduced diameter part so as to cover the outer circumference of the enlarged diameter part. The head of the reduced diameter part is welded, fixed and connected to the copper tube at the enlarged diameter part engageably in the axial direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
