摘要： PROBLEM TO BE SOLVED: To provide a tube end fitting capable of reliably preventing tube material from shifting in the axial direction or falling, in the tube end fitting to be attached to an end part of the tube material in which the inner and outer circumferential surfaces are made to be smooth and a reinforcing core is helically buried.SOLUTION: The tube end fitting includes: a nipple 11 which is internally fitted to an end part of the tube material 1 so as to be connected to other fitting; an elastic packing 12 which is externally fitted to the end part of the tube material 1; and a holder 13 which fastens the elastic packing 12 from the outside, presses the inner circumferential surface of the elastic packing 12 against the outer circumferential surface of the end part of the tube material 1 and, thereby, brings the end part of the tube material 1 into press-contact with the nipple 11. Retaining ribs 22, 22 for being caused to bite into the outer circumferential surface of the end part of the tube material 1 are protrusively disposed on the inner circumferential surface of the elastic packing 12. The retaining ribs 22, 22 are formed to have the same lead length as that of the helix of the reinforcing core 3 and to have a multiple thread shape having the number of threads more than that of the reinforcing core 3.
