PROBLEM TO BE SOLVED: To provide a tubular body insertion carriage capable of being mounted on tubular bodies of various outer diameters to be used, and securing sufficient electric insulation. SOLUTION: This tubular body insertion carriage 10 is composed of an upper band 30 composed of a pipe spacer made out of a resin and covering an upper outer periphery of the tubular body 12, and a lower band 40 comprising a roller supporting part 42 covering and supporting a lower outer periphery of the tubular body 12 and rotatably supporting a plurality of axially running rollers 21, 22. The bands are respectively made out of a flexible resin material, provided with flange parts for connection 33, 34, 43 on their circumferential end parts, the sum of inner peripheral lengths of each band is shorter than an outer peripheral length of the tubular body, and the tubular body is fastened and fixed by using the lower band having the peripheral length same as the tubular bodies of various outer diameters and the upper band selected from commercially available standard products of resin pipe spacers. Further a resin reinforcement plate 50 for inhibiting the flexure of the roller supporting part is mounted along the roller supporting part. COPYRIGHT: (C)2004,JPO
