PROBLEM TO BE SOLVED: To provide an intra-tube inner surface treatment device with which elevated-spot work can be performed without time and efforts or risk even for a vertical type hollow tube, intra-tube washing or adhesive coating can be performed relatively stably and uniformly and further, prior to an adhesion process, ground treatment can be performed on an inner surface relatively uniformly or stably.SOLUTION: An inner surface treatment device comprises an expanded plate 2 which is mounted in a terminal portion or an intermediate portion of a long guide wire that can be led into a tubular body, plate-shaped in such a size as to include a cross-sectional shape of the inside of the tubular body, and expanded around the side. At least an edge part of the expanded plate 2 itself is made of an elastic material and a plurality of slits 2C are formed along with the edge part. The edge part of the expanded plate 2 inserted to the tubular body is pushed with the inner surface of the tubular body and elastically deformed and the expanded plate is moved as a whole within the tubular body while keeping the state where the expanded plate is converged within the tubular body. Therefore, the edge part is slid on the tube inner surface with elastic reaction and tube inner surface treatment is performed. |
