PROBLEM TO BE SOLVED: To provide a hose joint of a liquid injection recording device capable of preventing the leakage of ink while reducing a manufacturing cost by simplifying a structure of a mold, a liquid injection head, and a liquid injection recording device.SOLUTION: A hose joint of a liquid injection recording device is equipped with a cylindrical joint body 102 in which an ink hose can be inserted; and slip preventive rings 103 and 104 integrally molded in ring-shapes over the whole of an outer peripheral surface of the joint body 102. The outermost diameter portion of the second slip preventive ring 104 formed nearest to on a receiving side of the ink hose is set on a parting line PL1 at molding. The second slip preventive ring 104 is made by integrally molding a first slip preventive piece 105 positioned on the receiving side of the ink hose around the parting line PL1, and a second slip preventive piece 106 positioned on the opposite side to the receiving side.SELECTED DRAWING: Figure 8 |
