Patent number: 7322091Abstract: This invention relates to a vibration isolating bushing, for example, built into a suspension system, an inside diameter of one edge (4) of an inner cylinder (1) being made larger than that of the other edge (6). The outside diameter of the thinner edge (4) is enlarged by applying pressure with a pressure forming jig (26) to the thicker edge surface (25), with the thinner edge surface (20) of the inner cylinder (1) abutted on a base (23). After completion of enlargement of the outside diameter of the thinner edge (4), the outside diameter of the thicker edge (6) is enlarged by further pressure with the pressure forming jig (26), this process thus capable of enlarging the outside diameter of both edges (4), (6) with one continuous working step.Type: GrantFiled: July 11, 2001Date of Patent: January 29, 2008Assignee: Toyo Tire & Rubber Co., Ltd.Inventors: Akihiko Katoh, Tadayuki Suzuki
