PROBLEM TO BE SOLVED: To improve durability of a rubber elastic body without causing an increase in manufacturing cost. SOLUTION: An inner cylinder assembly 33 is comprised of an inner cylinder 21, an auxiliary outer cylinder 35, and a thick rubber elastic body 23 linking them. An outer cylinder assembly 34 is comprised of an outer cylinder 22, auxiliary inner cylinders 38 and 39, and thin rubber elastic bodies 24 and 26 linking them. The thin rubber elastic bodies 24 and 26 of the outer cylinder assembly 34 are inclined in advance in a direction in which the inner cylinder invades during assembling of the inner and outer cylinder assemblies 33 and 34, and formed. When the inner and outer rubber assemblies 33 and 34 are assembled, the thin rubber elastic bodies 26 and 24 are compressed and deformed so as to orient in a substantially vertical direction to the outer cylinder 22, and the inner cylinder 21 is pressed in the auxiliary inner cylinders 39 and 38, and is fixed. |
