PROBLEM TO BE SOLVED: To obtain a vibration isolation device in which attaines not only a manufacturing cost reduction but also a space-saving as well as an easy detachment brought about by thinning and flattening an abutting member. SOLUTION: A pair of rubber elastic bodies 16A, 16B, each formed in a ring-like shape by using rubber material, is each bonded by means of vulcanization on inner circumferential surfaces in a pair of external tubiform metallic bodies 12A, 12B. An internal tubiform metallic body 18 formed in a cylindrical shape is arranged on an inner circumferential surface of the rubber elastic body 16A located in a downside. A joining member 20 formed in a columnar shape is arranged on an inner circumferential surface of the rubber elastic body 16B located in an upside. A narrow diametrical portion 20A of the joining member 20 is allowed to penetrate into the internal tubiform metallic body 18, and, as a result, one axial ends of the rubber elastic bodies 16A, 16B are allowed to be mutually opposed. Plates 26A, 26B are fixed to both ends of the joining member 20, respectively, and are arranged on the other axial ends of the rubber elastic bodies 16A, 16B. COPYRIGHT: (C)2008,JPO&INPIT |
