PROBLEM TO BE SOLVED: To provide a supporting method of a tube, in which an exposed tube fixed to a bridge or the like is prevented from thermally expanding/contracting caused by change in outside air temperature thereby to prevent the tube from largely meandering or from detaching from a joint caused by tensile force applied on the joint connecting the tubes. SOLUTION: Clamp metal fittings 12 attached to a bridge catch the resin tube 11 at a suitable interval to fix the resin tube. Therefore, a thermal expansion and contraction amount of sections A, B between the clamp metal fittings 12 is reduced and dispersed.
