<p><P>PROBLEM TO BE SOLVED: To provide a connecting structure of a handrail and a welding fixture for the handrail, which can bring about an excellent appearance by simple working. <P>SOLUTION: In this connecting structure of the handrail, a metal core tube is exposed by removing a resin-coated part, with an arbitrary length from an end surface of a resin-coated metal tube, of the resin-coated metal tube wherein the resin-coated part having almost the same outside diameter as a metal tube is provided on the metal tube and an outer peripheral part of the metal core tube having an outside diameter almost as large as an inside diameter of the metal tube; the exposed metal core tube of the resin-coated tube is inserted into the metal tube, so that the the exposed metal core tube is joined by welding from a hole which is opened in the outer peripheral surface of the metal tube; and a part, near the metal core tube, of the resin-coated part of the resin-coated tube brought into contact with an end surface of the metal tube is formed in such a tapered shape that a diameter is reduced in the direction of the end surface of the metal tube. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
