PROBLEM TO BE SOLVED: To provide a tube allowed to be bound up together with a plurality of tubes on a suitable binding position because if the plurality of tubes are bound up on an unsuitable binding position, deflection or tension may be generated in the tubes, a deflected tube may be caught in a movable part or a tense tube may be damaged due to rubbing against a binding band or a device inner structure.SOLUTION: A tube 11 allowing a fluid to flow in its inside includes a binding mark printed on the tube 11 and indicating a binding position allowing the tube to be bound up together with other tubes. Preferably, the binding mark 13 has an asymmetrical shape in right-and-left and/or vertically and the binding mark 13 can identify a direction of the tube 11 when binding up the tube 11 together with other tubes. |
