Claims

[Scope of utility model registration request]

(1) A flexible outer cylinder, a core wire that is inserted into the outer cylinder and moves relative to the outer cylinder in the axial direction, and an E that engages with an annular groove or a through hole at one end of the core wire. In a traction device consisting of a fixing device such as a ring or a snap bottle, and a disk-shaped stopper through which the core wire passes through a center hole and is held in contact with the outer cylinder side of the fixing device, the stopper is attached to the fixing device. 1. A traction tool characterized in that it is disc-shaped with a diameter longer than the length of the tool, and has a protrusion on the inner peripheral surface of its center hole that projects toward the center and is pressed by the core wire.

(2) The towing tool according to claim 1, wherein the protrusion is parallel to the axial direction and has a mountain-like shape that increases in height from one end toward the other end.

(3) The traction tool according to claim 2, wherein the stopper has a circular recess into which the fixture fits on the side that comes into contact with the fixture.
