PURPOSE: To be enabled to diminish the force necessary for winding on and pulling out by making possible to winding on a rubber tube, forming a scroll along a winding spool with the revolution of a winding-on bar in a winding-on device for rubber tubes of gas.

CONSTITUTION: When a rubber tube 1 is pulled with a pulling force F which is applied against the force of a twist-and-press spring 7, a winding-on bar 3 is transported to the direction of a bottom board 12 along a spiral groove 5, and said rubber tube 1 is forced to be bent toward the direction of an outlet 8 for said rubber tube from the direction along said groove 5 successively and pulled out. And when the pulling force F and said spring force are ballanced, the pulling-out of said rubber tube is stopped. In the case of winding-on of said rubber tube 1, by the removal of said pulling force F, said rubber tube 1 is wound on with a spring 7, transporting said winding-on bar 3 to the reverse direction forming a spiral. Therefore, the pulling amount of said rubber tube 1 can be varied by controlling said pulling force F. Moreover, the force necessary for winding-on and pulling out can be diminished as only said winding-on bar is transported without the revolution of said winding spool.
