PROBLEM TO BE SOLVED: To ease a stress generated in a tube which connects a liquid jetting head and a liquid supply source with each other. SOLUTION: A tube guide 8 is arranged on the outer peripheral side of bending of the tubes 6 in a plan view of parts between an inkjet head and the fixed parts 6a of the four tubes 6. Five ribs 15 are formed to an opposed surface 8a extended in a scan direction and a vertical direction in contact opposingly to the parts of the tubes 6 on the tube guide 8. The five ribs 15 each extend in the scan direction and hold the tubes 6 individually from up and down directions. The rib 15 is made shorter in length with respect to the up-down direction as is away from the fixed part 6a with respect to the scan direction. The rate of change of the length with respect to the vertical direction to change in the scan direction is made larger at the end of the opposite side to the fixed part 6a than at other parts. Thus the interval D1 of the ribs 15 becomes larger as is away from the fixed part 6a with respect to the scan direction. COPYRIGHT: (C)2010,JPO&INPIT |
