Abstract
A process for producing a vibration isolator. The process involves steps of forming an intermediate product including an axial member, an outside member having a cylinder-shaped portion and a rubber elastic member, and drawing the cylinder-shaped portion with a drawing apparatus provided with a drawing hole at least by pressing the cylinder-shaped portion into the drawing hole. The drawing hole has a predetermined dimensional diameter being smaller than an outer peripheral diameter of the cylinder-shaped portion. Thus, the cylinder-shaped portion is reduced diametrically to plastically deform. The production process can obviate the conventional pressed-in construction in which metallic members contact with each other, can make the manufacture of the vibration isolator easy, and can reduce the manufacturing cost.
