VEHICLE-SUSPENSION SHRINKABLE-TUBE PRODUCING DEVICE AND A SHRINKABLE-TUBE PRODUCTION METHOD USING SAME

A vehicle suspension thermally shrinkable tube of the present invention is formed in a shape corresponding to a vehicle-suspension coil spring having a spiral shape and is formed so as to have a larger diameter than the diameter of the spring so as to allow the spring to be coupled by insertion; and is formed from a material the volume of which shrinks upon applying heat when the spring is coupled by insertion; and, after the spring has been slotted in and coupled, heat is applied and said tube is made to attach intimately to the spring.
