PROBLEM TO BE SOLVED: To provide, at a low price, a reinforcement structure or tubular member that has superior low extensibility and is free of wire breaking, etc., and superior in mechanical strength according to the present invention so as to solve the problem in which since the tubular member is inserted in advance so as to transport a gas, a liquid, an instrument, etc., to thin piping and a narrow place, and partially extends because of resistance force of a tube wall of an inserted body to cause a decrease in alignment when the tubular member is repeatedly inserted into and extracted from a narrow region of piping etc.SOLUTION: A tubular member has a reinforcement structure characterized in that tubular braiding made of metal wires is provided with at least one or more coil windings as an extension suppressing member at an outer periphery and at least a length-directional part of the tubular braiding.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】 管状部材は、細い配管や狭所へガスや液体、器具類等を搬送するために、予め挿入されるものであり、配管等の細い部位に、管状部材を繰り返し挿入したり、引き抜いたりする場合、被挿入体の管壁との抵抗力により、部材の一部が伸び、位置調整性が低下する問題があり、本発明は、低伸長性に優れ、かつ、断線等の発生がなく機械的強度に優れる補強構造体又は管状部材を、安価に提供することを課題とする。【解決手段】 金属線からなる管状編組において、管状編組の外周かつ長手方向の少なくとも一部に、伸び抑制部材として、少なくとも1本以上のコイル巻きを施すことを特徴とする補強構造体を有する。【選択図】図1
