PROBLEM TO BE SOLVED: To provide a fluid feeding apparatus for decreasing a load on movement of a carriage while irregular movement of a fluid feeding tube is suppressed. SOLUTION: The fluid feeding apparatus includes a carriage 8 which carries a recording head and moves back and forth in the main scanning direction, an ink feeding tube 13 for feeding ink to the recording head, and a steel belt 21 for supporting the ink feeding tube 13. The ink feeding tube 13 and the steel belt 21 are respectively connected with the carriage 8 on their end parts under a condition of arrangement in stacks, and they are curved into U shapes and the other end parts are connected with the connecting parts 14 of an apparatus main body. As the steel belt 21, a thin sheet member which is elastically deformed into a first equilibrium condition where the cross-section in the width direction is shaped into a gutter-shaped curve and the cross-section in the longitudinal direction is shaped into a straight line, and into a second equilibrium condition where an external force is added to this first equilibrium condition, and the cross-section in the width direction is shaped into a straight line and the cross-section in the longitudinal direction is shaped into a ring as a whole, is used.
