を結合するための拡管治具。A cylindrical crimp die inserted into a plurality of tubes that are fitted together to be joined together, a crimp die holder that holds the crimp die, and a tip end of the crimp die divided into multiple parts along the axial direction of the crimp die. A tube expansion die and a tube inner deformation prevention die are formed on the tip side of the crimp die and are formed alternately in the circumferential direction of the crimp die, and a tube expansion die and a tube inner surface deformation prevention die are formed on the tip of the tube expansion die in the radial direction of the crimp die. A ball is fitted into the hole so as to be movable in the same direction as the hole, and is capable of moving in and out of the inner and outer diameter surfaces of the tube expansion die, and is prevented from escaping outward from the outer diameter surface of the tube. and is fitted into the crimp die coaxially and movably in the axial direction of the crimp die, so as to be able to contact the inner diameter surface of the tube inner deformation prevention gouer and the ball, and to move the ball by relative movement with the crimp die. A pipe expansion jig for joining pipes, comprising a taper pin that protrudes and retracts from the outer diameter surface of the pipe expansion die.
