Claims

[Scope of utility model registration request]

(1) A cylindrical crimp die that has a cylindrical holder and a radially movable pressing part at the tip, and is provided at the tip of the holder with its axis aligned with the axis of the holder. ', a rond having a tapered part at its tip for moving the pressing part in the radial direction of the crimp die and slidably provided on the holder, and a rear end of the rond protruding from the holder. a lever rotatably provided at the lever; and a link having one end rotatably provided at the rear end of the holder and the other end rotatably provided at a midway portion of the lever. A tube expansion jig characterized by the ability to

(2) The crimp die has, at its tip, a goo part for preventing deformation of the inner surface of the tube, in which the tapered part slides into contact with the inner peripheral surface, and a gouer part for expanding the tube, which has a through hole penetrating from the inner peripheral surface to the outer peripheral surface. are formed alternately in the circumferential direction, and the pressing portion is
